By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

+ Parsing the Base Configuration Metadata + + + The first thing BitBake does is parse base configuration + metadata. + Base configuration metadata consists of your project's + bblayers.conf file to determine what + layers BitBake needs to recognize, all necessary + layer.conf files (one from each layer), + and bitbake.conf. + The data itself is of various types: + + Recipes: + Details about particular pieces of software. + + Class Data: + An abstraction of common build information + (e.g. how to build a Linux kernel). + + Configuration Data: + Machine-specific settings, policy decisions, + and so forth. + Configuration data acts as the glue to bind everything + together. + + + + + The layer.conf files are used to + construct key variables such as + BBPATH + and + BBFILES. + BBPATH is used to search for + configuration and class files under the + conf and classes + directories, respectively. + BBFILES is used to locate both recipe + and recipe append files + (.bb and .bbappend). + If there is no bblayers.conf file, + it is assumed the user has set the BBPATH + and BBFILES directly in the environment. + + + + Next, the bitbake.conf file is located + using the BBPATH variable that was + just constructed. + The bitbake.conf file may also include other + configuration files using the + include or + require directives. + + + + Prior to parsing configuration files, Bitbake looks + at certain variables, including: + + + BB_ENV_WHITELIST + + + BB_ENV_EXTRAWHITE + + + BB_PRESERVE_ENV + + + BB_ORIGENV + + + BITBAKE_UI + + + The first four variables in this list relate to how BitBake treats shell + environment variables during task execution. + By default, BitBake cleans the environment variables and provides tight + control over the shell execution environment. + However, through the use of these first four variables, you can + apply your control regarding the + environment variables allowed to be used by BitBake in the shell + during execution of tasks. + See the + "Passing Information Into the Build Task Environment" + section and the information about these variables in the + variable glossary for more information on how they work and + on how to use them. + + + + The base configuration metadata is global + and therefore affects all recipes and tasks that are executed. + + + + BitBake first searches the current working directory for an + optional conf/bblayers.conf configuration file. + This file is expected to contain a + BBLAYERS + variable that is a space-delimited list of 'layer' directories. + Recall that if BitBake cannot find a bblayers.conf + file, then it is assumed the user has set the BBPATH + and BBFILES variables directly in the environment. + + + + For each directory (layer) in this list, a conf/layer.conf + file is located and parsed with the + LAYERDIR + variable being set to the directory where the layer was found. + The idea is these files automatically set up + BBPATH + and other variables correctly for a given build directory. + + + + BitBake then expects to find the conf/bitbake.conf + file somewhere in the user-specified BBPATH. + That configuration file generally has include directives to pull + in any other metadata such as files specific to the architecture, + the machine, the local environment, and so forth. + + + + Only variable definitions and include directives are allowed + in BitBake .conf files. + Some variables directly influence BitBake's behavior. + These variables might have been set from the environment + depending on the environment variables previously + mentioned or set in the configuration files. + The + "Variables Glossary" + chapter presents a full list of variables. + + + + After parsing configuration files, BitBake uses its rudimentary + inheritance mechanism, which is through class files, to inherit + some standard classes. + BitBake parses a class when the inherit directive responsible + for getting that class is encountered. + + + + The base.bbclass file is always included. + Other classes that are specified in the configuration using the + INHERIT + variable are also included. + BitBake searches for class files in a + classes subdirectory under + the paths in BBPATH in the same way as + configuration files. + + + + A good way to get an idea of the configuration files and + the class files used in your execution environment is to + run the following BitBake command: + + $ bitbake -e > mybb.log + + Examining the top of the mybb.log + shows you the many configuration files and class files + used in your execution environment. + + + + + You need to be aware of how BitBake parses curly braces. + If a recipe uses a closing curly brace within the function and + the character has no leading spaces, BitBake produces a parsing + error. + If you use a pair of curly braces in a shell function, the + closing curly brace must not be located at the start of the line + without leading spaces. + + + + Here is an example that causes BitBake to produce a parsing + error: + + fakeroot create_shar() { + cat << "EOF" > ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh + usage() + { + echo "test" + ###### The following "}" at the start of the line causes a parsing error ###### + } + EOF + } + + Writing the recipe this way avoids the error: + + fakeroot create_shar() { + cat << "EOF" > ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh + usage() + { + echo "test" + ######The following "}" with a leading space at the start of the line avoids the error ###### + } + EOF + } + + + +
+ +
+ Locating and Parsing Recipes + + + During the configuration phase, BitBake will have set + BBFILES. + BitBake now uses it to construct a list of recipes to parse, + along with any append files (.bbappend) + to apply. + BBFILES is a space-separated list of + available files and supports wildcards. + An example would be: + + BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend" + + BitBake parses each recipe and append file located + with BBFILES and stores the values of + various variables into the datastore. + + Append files are applied in the order they are encountered in + BBFILES. + + For each file, a fresh copy of the base configuration is + made, then the recipe is parsed line by line. + Any inherit statements cause BitBake to find and + then parse class files (.bbclass) + using + BBPATH + as the search path. + Finally, BitBake parses in order any append files found in + BBFILES. + + + + One common convention is to use the recipe filename to define + pieces of metadata. + For example, in bitbake.conf the recipe + name and version are used to set the variables + PN and + PV: + + PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}" + PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}" + + In this example, a recipe called "something_1.2.3.bb" would set + PN to "something" and + PV to "1.2.3". + + + + By the time parsing is complete for a recipe, BitBake + has a list of tasks that the recipe defines and a set of + data consisting of keys and values as well as + dependency information about the tasks. + + + + BitBake does not need all of this information. + It only needs a small subset of the information to make + decisions about the recipe. + Consequently, BitBake caches the values in which it is + interested and does not store the rest of the information. + Experience has shown it is faster to re-parse the metadata than to + try and write it out to the disk and then reload it. + + + + Where possible, subsequent BitBake commands reuse this cache of + recipe information. + The validity of this cache is determined by first computing a + checksum of the base configuration data (see + BB_HASHCONFIG_WHITELIST) + and then checking if the checksum matches. + If that checksum matches what is in the cache and the recipe + and class files have not changed, Bitbake is able to use + the cache. + BitBake then reloads the cached information about the recipe + instead of reparsing it from scratch. + + + + Recipe file collections exist to allow the user to + have multiple repositories of + .bb files that contain the same + exact package. + For example, one could easily use them to make one's + own local copy of an upstream repository, but with + custom modifications that one does not want upstream. + Here is an example: + + BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb" + BBFILE_COLLECTIONS = "upstream local" + BBFILE_PATTERN_upstream = "^/stuff/openembedded/" + BBFILE_PATTERN_local = "^/stuff/openembedded.modified/" + BBFILE_PRIORITY_upstream = "5" + BBFILE_PRIORITY_local = "10" + + + The layers mechanism is now the preferred method of collecting + code. + While the collections code remains, its main use is to set layer + priorities and to deal with overlap (conflicts) between layers. + + +
+ +
+ Providers + + + Assuming BitBake has been instructed to execute a target + and that all the recipe files have been parsed, BitBake + starts to figure out how to build the target. + BitBake looks through the PROVIDES list + for each of the recipes. + A PROVIDES list is the list of names by which + the recipe can be known. + Each recipe's PROVIDES list is created + implicitly through the recipe's + PN variable + and explicitly through the recipe's + PROVIDES + variable, which is optional. + + + + When a recipe uses PROVIDES, that recipe's + functionality can be found under an alternative name or names other + than the implicit PN name. + As an example, suppose a recipe named keyboard_1.0.bb + contained the following: + + PROVIDES += "fullkeyboard" + + The PROVIDES list for this recipe becomes + "keyboard", which is implicit, and "fullkeyboard", which is explicit. + Consequently, the functionality found in + keyboard_1.0.bb can be found under two + different names. + +
+ +
+ Preferences + + + The PROVIDES list is only part of the solution + for figuring out a target's recipes. + Because targets might have multiple providers, BitBake needs + to prioritize providers by determining provider preferences. + + + + A common example in which a target has multiple providers + is "virtual/kernel", which is on the + PROVIDES list for each kernel recipe. + Each machine often selects the best kernel provider by using a + line similar to the following in the machine configuration file: + + PREFERRED_PROVIDER_virtual/kernel = "linux-yocto" + + The default + PREFERRED_PROVIDER + is the provider with the same name as the target. + Bitbake iterates through each target it needs to build and + resolves them and their dependencies using this process. + + + + Understanding how providers are chosen is made complicated by the fact + that multiple versions might exist for a given provider. + BitBake defaults to the highest version of a provider. + Version comparisons are made using the same method as Debian. + You can use the + PREFERRED_VERSION + variable to specify a particular version. + You can influence the order by using the + DEFAULT_PREFERENCE + variable. + + + + By default, files have a preference of "0". + Setting DEFAULT_PREFERENCE to "-1" makes the + recipe unlikely to be used unless it is explicitly referenced. + Setting DEFAULT_PREFERENCE to "1" makes it + likely the recipe is used. + PREFERRED_VERSION overrides any + DEFAULT_PREFERENCE setting. + DEFAULT_PREFERENCE is often used to mark newer + and more experimental recipe versions until they have undergone + sufficient testing to be considered stable. + + + + When there are multiple “versions†of a given recipe, + BitBake defaults to selecting the most recent + version, unless otherwise specified. + If the recipe in question has a + DEFAULT_PREFERENCE + set lower than the other recipes (default is 0), then + it will not be selected. + This allows the person or persons maintaining + the repository of recipe files to specify + their preference for the default selected version. + Additionally, the user can specify their preferred version. + + + + If the first recipe is named a_1.1.bb, then the + PN variable + will be set to “aâ€, and the + PV + variable will be set to 1.1. + + + + Thus, if a recipe named a_1.2.bb exists, BitBake + will choose 1.2 by default. + However, if you define the following variable in a + .conf file that BitBake parses, you + can change that preference: + + PREFERRED_VERSION_a = "1.1" + + + + + + It is common for a recipe to provide two versions -- a stable, + numbered (and preferred) version, and a version that is + automatically checked out from a source code repository that + is considered more "bleeding edge" but can be selected only + explicitly. + + + + For example, in the OpenEmbedded codebase, there is a standard, + versioned recipe file for BusyBox, + busybox_1.22.1.bb, + but there is also a Git-based version, + busybox_git.bb, which explicitly contains the line + + DEFAULT_PREFERENCE = "-1" + + to ensure that the numbered, stable version is always preferred + unless the developer selects otherwise. + + +
+ +
+ Dependencies + + + Each target BitBake builds consists of multiple tasks such as + fetch, unpack, + patch, configure, + and compile. + For best performance on multi-core systems, BitBake considers each + task as an independent + entity with its own set of dependencies. + + + + Dependencies are defined through several variables. + You can find information about variables BitBake uses in + the Variables Glossary + near the end of this manual. + At a basic level, it is sufficient to know that BitBake uses the + DEPENDS and + RDEPENDS variables when + calculating dependencies. + + + + For more information on how BitBake handles dependencies, see the + "Dependencies" section. + +
+ +
+ The Task List + + + Based on the generated list of providers and the dependency information, + BitBake can now calculate exactly what tasks it needs to run and in what + order it needs to run them. + The + "Executing Tasks" section has more + information on how BitBake chooses which task to execute next. + + + + The build now starts with BitBake forking off threads up to the limit set in the + BB_NUMBER_THREADS + variable. + BitBake continues to fork threads as long as there are tasks ready to run, + those tasks have all their dependencies met, and the thread threshold has not been + exceeded. + + + + It is worth noting that you can greatly speed up the build time by properly setting + the BB_NUMBER_THREADS variable. + + + + As each task completes, a timestamp is written to the directory specified by the + STAMP variable. + On subsequent runs, BitBake looks in the build directory within + tmp/stamps and does not rerun + tasks that are already completed unless a timestamp is found to be invalid. + Currently, invalid timestamps are only considered on a per + recipe file basis. + So, for example, if the configure stamp has a timestamp greater than the + compile timestamp for a given target, then the compile task would rerun. + Running the compile task again, however, has no effect on other providers + that depend on that target. + + + + The exact format of the stamps is partly configurable. + In modern versions of BitBake, a hash is appended to the + stamp so that if the configuration changes, the stamp becomes + invalid and the task is automatically rerun. + This hash, or signature used, is governed by the signature policy + that is configured (see the + "Checksums (Signatures)" + section for information). + It is also possible to append extra metadata to the stamp using + the [stamp-extra-info] task flag. + For example, OpenEmbedded uses this flag to make some tasks machine-specific. + + + + Some tasks are marked as "nostamp" tasks. + No timestamp file is created when these tasks are run. + Consequently, "nostamp" tasks are always rerun. + + + + For more information on tasks, see the + "Tasks" section. + +
+ +
+ Executing Tasks + + + Tasks can be either a shell task or a Python task. + For shell tasks, BitBake writes a shell script to + ${T}/run.do_taskname.pid + and then executes the script. + The generated shell script contains all the exported variables, + and the shell functions with all variables expanded. + Output from the shell script goes to the file + ${T}/log.do_taskname.pid. + Looking at the expanded shell functions in the run file and + the output in the log files is a useful debugging technique. + + + + For Python tasks, BitBake executes the task internally and logs + information to the controlling terminal. + Future versions of BitBake will write the functions to files + similar to the way shell tasks are handled. + Logging will be handled in a way similar to shell tasks as well. + + + + The order in which BitBake runs the tasks is controlled by its + task scheduler. + It is possible to configure the scheduler and define custom + implementations for specific use cases. + For more information, see these variables that control the + behavior: + + + BB_SCHEDULER + + + BB_SCHEDULERS + + + It is possible to have functions run before and after a task's main + function. + This is done using the [prefuncs] + and [postfuncs] flags of the task + that lists the functions to run. + +
+ +
+ Checksums (Signatures) + + + A checksum is a unique signature of a task's inputs. + The signature of a task can be used to determine if a task + needs to be run. + Because it is a change in a task's inputs that triggers running + the task, BitBake needs to detect all the inputs to a given task. + For shell tasks, this turns out to be fairly easy because + BitBake generates a "run" shell script for each task and + it is possible to create a checksum that gives you a good idea of when + the task's data changes. + + + + To complicate the problem, some things should not be included in + the checksum. + First, there is the actual specific build path of a given task - + the working directory. + It does not matter if the working directory changes because it should not + affect the output for target packages. + The simplistic approach for excluding the working directory is to set + it to some fixed value and create the checksum for the "run" script. + BitBake goes one step better and uses the + BB_HASHBASE_WHITELIST + variable to define a list of variables that should never be included + when generating the signatures. + + + + Another problem results from the "run" scripts containing functions that + might or might not get called. + The incremental build solution contains code that figures out dependencies + between shell functions. + This code is used to prune the "run" scripts down to the minimum set, + thereby alleviating this problem and making the "run" scripts much more + readable as a bonus. + + + + So far we have solutions for shell scripts. + What about Python tasks? + The same approach applies even though these tasks are more difficult. + The process needs to figure out what variables a Python function accesses + and what functions it calls. + Again, the incremental build solution contains code that first figures out + the variable and function dependencies, and then creates a checksum for the data + used as the input to the task. + + + + Like the working directory case, situations exist where dependencies + should be ignored. + For these cases, you can instruct the build process to ignore a dependency + by using a line like the following: + + PACKAGE_ARCHS[vardepsexclude] = "MACHINE" + + This example ensures that the PACKAGE_ARCHS variable does not + depend on the value of MACHINE, even if it does reference it. + + + + Equally, there are cases where we need to add dependencies BitBake + is not able to find. + You can accomplish this by using a line like the following: + + PACKAGE_ARCHS[vardeps] = "MACHINE" + + This example explicitly adds the MACHINE variable as a + dependency for PACKAGE_ARCHS. + + + + Consider a case with in-line Python, for example, where BitBake is not + able to figure out dependencies. + When running in debug mode (i.e. using -DDD), BitBake + produces output when it discovers something for which it cannot figure out + dependencies. + + + + Thus far, this section has limited discussion to the direct inputs into a task. + Information based on direct inputs is referred to as the "basehash" in the + code. + However, there is still the question of a task's indirect inputs - the + things that were already built and present in the build directory. + The checksum (or signature) for a particular task needs to add the hashes + of all the tasks on which the particular task depends. + Choosing which dependencies to add is a policy decision. + However, the effect is to generate a master checksum that combines the basehash + and the hashes of the task's dependencies. + + + + At the code level, there are a variety of ways both the basehash and the + dependent task hashes can be influenced. + Within the BitBake configuration file, we can give BitBake some extra information + to help it construct the basehash. + The following statement effectively results in a list of global variable + dependency excludes - variables never included in any checksum. + This example uses variables from OpenEmbedded to help illustrate + the concept: + + BB_HASHBASE_WHITELIST ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH DL_DIR \ + SSTATE_DIR THISDIR FILESEXTRAPATHS FILE_DIRNAME HOME LOGNAME SHELL TERM \ + USER FILESPATH STAGING_DIR_HOST STAGING_DIR_TARGET COREBASE PRSERV_HOST \ + PRSERV_DUMPDIR PRSERV_DUMPFILE PRSERV_LOCKDOWN PARALLEL_MAKE \ + CCACHE_DIR EXTERNAL_TOOLCHAIN CCACHE CCACHE_DISABLE LICENSE_PATH SDKPKGSUFFIX" + + The previous example excludes the work directory, which is part of + TMPDIR. + + + + The rules for deciding which hashes of dependent tasks to include through + dependency chains are more complex and are generally accomplished with a + Python function. + The code in meta/lib/oe/sstatesig.py shows two examples + of this and also illustrates how you can insert your own policy into the system + if so desired. + This file defines the two basic signature generators OpenEmbedded-Core + uses: "OEBasic" and "OEBasicHash". + By default, there is a dummy "noop" signature handler enabled in BitBake. + This means that behavior is unchanged from previous versions. + OE-Core uses the "OEBasicHash" signature handler by default + through this setting in the bitbake.conf file: + + BB_SIGNATURE_HANDLER ?= "OEBasicHash" + + The "OEBasicHash" BB_SIGNATURE_HANDLER is the same as the + "OEBasic" version but adds the task hash to the stamp files. + This results in any metadata change that changes the task hash, automatically + causing the task to be run again. + This removes the need to bump + PR + values, and changes to metadata automatically ripple across the build. + + + + It is also worth noting that the end result of these signature generators is to + make some dependency and hash information available to the build. + This information includes: + + BB_BASEHASH_task-taskname: + The base hashes for each task in the recipe. + + BB_BASEHASH_filename:taskname: + The base hashes for each dependent task. + + BBHASHDEPS_filename:taskname: + The task dependencies for each task. + + BB_TASKHASH: + The hash of the currently running task. + + + + + + It is worth noting that BitBake's "-S" option lets you + debug Bitbake's processing of signatures. + The options passed to -S allow different debugging modes + to be used, either using BitBake's own debug functions + or possibly those defined in the metadata/signature handler + itself. + The simplest parameter to pass is "none", which causes a + set of signature information to be written out into + STAMPS_DIR + corresponding to the targets specified. + The other currently available parameter is "printdiff", + which causes BitBake to try to establish the closest + signature match it can (e.g. in the sstate cache) and then + run bitbake-diffsigs over the matches + to determine the stamps and delta where these two + stamp trees diverge. + + It is likely that future versions of BitBake will + provide other signature handlers triggered through + additional "-S" parameters. + + + + + You can find more information on checksum metadata in the + "Task Checksums and Setscene" + section. + +
+ +
+ Setscene + + + The setscene process enables BitBake to handle "pre-built" artifacts. + The ability to handle and reuse these artifacts allows BitBake + the luxury of not having to build something from scratch every time. + Instead, BitBake can use, when possible, existing build artifacts. + + + + BitBake needs to have reliable data indicating whether or not an + artifact is compatible. + Signatures, described in the previous section, provide an ideal + way of representing whether an artifact is compatible. + If a signature is the same, an object can be reused. + + + + If an object can be reused, the problem then becomes how to + replace a given task or set of tasks with the pre-built artifact. + BitBake solves the problem with the "setscene" process. + + + + When BitBake is asked to build a given target, before building anything, + it first asks whether cached information is available for any of the + targets it's building, or any of the intermediate targets. + If cached information is available, BitBake uses this information instead of + running the main tasks. + + + + BitBake first calls the function defined by the + BB_HASHCHECK_FUNCTION + variable with a list of tasks and corresponding + hashes it wants to build. + This function is designed to be fast and returns a list + of the tasks for which it believes in can obtain artifacts. + + + + Next, for each of the tasks that were returned as possibilities, + BitBake executes a setscene version of the task that the possible + artifact covers. + Setscene versions of a task have the string "_setscene" appended to the + task name. + So, for example, the task with the name xxx has + a setscene task named xxx_setscene. + The setscene version of the task executes and provides the necessary + artifacts returning either success or failure. + + + + As previously mentioned, an artifact can cover more than one task. + For example, it is pointless to obtain a compiler if you + already have the compiled binary. + To handle this, BitBake calls the + BB_SETSCENE_DEPVALID + function for each successful setscene task to know whether or not it needs + to obtain the dependencies of that task. + + + + Finally, after all the setscene tasks have executed, BitBake calls the + function listed in + BB_SETSCENE_VERIFY_FUNCTION2 + with the list of tasks BitBake thinks has been "covered". + The metadata can then ensure that this list is correct and can + inform BitBake that it wants specific tasks to be run regardless + of the setscene result. + + + + You can find more information on setscene metadata in the + "Task Checksums and Setscene" + section. + +

+ The Download (Fetch) + + + BitBake takes several steps when fetching source code or files. + The fetcher codebase deals with two distinct processes in order: + obtaining the files from somewhere (cached or otherwise) + and then unpacking those files into a specific location and + perhaps in a specific way. + Getting and unpacking the files is often optionally followed + by patching. + Patching, however, is not covered by this module. + + + + The code to execute the first part of this process, a fetch, + looks something like the following: + + src_uri = (d.getVar('SRC_URI') or "").split() + fetcher = bb.fetch2.Fetch(src_uri, d) + fetcher.download() + + This code sets up an instance of the fetch class. + The instance uses a space-separated list of URLs from the + SRC_URI + variable and then calls the download + method to download the files. + + + + The instantiation of the fetch class is usually followed by: + + rootdir = l.getVar('WORKDIR') + fetcher.unpack(rootdir) + + This code unpacks the downloaded files to the + specified by WORKDIR. + + For convenience, the naming in these examples matches + the variables used by OpenEmbedded. + If you want to see the above code in action, examine + the OpenEmbedded class file base.bbclass. + + The SRC_URI and WORKDIR + variables are not hardcoded into the fetcher, since those fetcher + methods can be (and are) called with different variable names. + In OpenEmbedded for example, the shared state (sstate) code uses + the fetch module to fetch the sstate files. + + + + When the download() method is called, + BitBake tries to resolve the URLs by looking for source files + in a specific search order: + + Pre-mirror Sites: + BitBake first uses pre-mirrors to try and find source files. + These locations are defined using the + PREMIRRORS + variable. + + Source URI: + If pre-mirrors fail, BitBake uses the original URL (e.g from + SRC_URI). + + Mirror Sites: + If fetch failures occur, BitBake next uses mirror locations as + defined by the + MIRRORS + variable. + + + + + + For each URL passed to the fetcher, the fetcher + calls the submodule that handles that particular URL type. + This behavior can be the source of some confusion when you + are providing URLs for the SRC_URI + variable. + Consider the following two URLs: + + http://git.yoctoproject.org/git/poky;protocol=git + git://git.yoctoproject.org/git/poky;protocol=http + + In the former case, the URL is passed to the + wget fetcher, which does not + understand "git". + Therefore, the latter case is the correct form since the + Git fetcher does know how to use HTTP as a transport. + + + + Here are some examples that show commonly used mirror + definitions: + + PREMIRRORS ?= "\ + bzr://.*/.* http://somemirror.org/sources/ \n \ + cvs://.*/.* http://somemirror.org/sources/ \n \ + git://.*/.* http://somemirror.org/sources/ \n \ + hg://.*/.* http://somemirror.org/sources/ \n \ + osc://.*/.* http://somemirror.org/sources/ \n \ + p4://.*/.* http://somemirror.org/sources/ \n \ + svn://.*/.* http://somemirror.org/sources/ \n" + + MIRRORS =+ "\ + ftp://.*/.* http://somemirror.org/sources/ \n \ + http://.*/.* http://somemirror.org/sources/ \n \ + https://.*/.* http://somemirror.org/sources/ \n" + + It is useful to note that BitBake supports + cross-URLs. + It is possible to mirror a Git repository on an HTTP + server as a tarball. + This is what the git:// mapping in + the previous example does. + + + + Since network accesses are slow, Bitbake maintains a + cache of files downloaded from the network. + Any source files that are not local (i.e. + downloaded from the Internet) are placed into the download + directory, which is specified by the + DL_DIR + variable. + + + + File integrity is of key importance for reproducing builds. + For non-local archive downloads, the fetcher code can verify + SHA-256 and MD5 checksums to ensure the archives have been + downloaded correctly. + You can specify these checksums by using the + SRC_URI variable with the appropriate + varflags as follows: + + SRC_URI[md5sum] = "value" + SRC_URI[sha256sum] = "value" + + You can also specify the checksums as parameters on the + SRC_URI as shown below: + + SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d" + + If multiple URIs exist, you can specify the checksums either + directly as in the previous example, or you can name the URLs. + The following syntax shows how you name the URIs: + + SRC_URI = "http://example.com/foobar.tar.bz2;name=foo" + SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d + + After a file has been downloaded and has had its checksum checked, + a ".done" stamp is placed in DL_DIR. + BitBake uses this stamp during subsequent builds to avoid + downloading or comparing a checksum for the file again. + + It is assumed that local storage is safe from data corruption. + If this were not the case, there would be bigger issues to worry about. + + + + + If + BB_STRICT_CHECKSUM + is set, any download without a checksum triggers an + error message. + The + BB_NO_NETWORK + variable can be used to make any attempted network access a fatal + error, which is useful for checking that mirrors are complete + as well as other things. + +
+ +
+ The Unpack + + + The unpack process usually immediately follows the download. + For all URLs except Git URLs, BitBake uses the common + unpack method. + + + + A number of parameters exist that you can specify within the + URL to govern the behavior of the unpack stage: + + unpack: + Controls whether the URL components are unpacked. + If set to "1", which is the default, the components + are unpacked. + If set to "0", the unpack stage leaves the file alone. + This parameter is useful when you want an archive to be + copied in and not be unpacked. + + dos: + Applies to .zip and + .jar files and specifies whether to + use DOS line ending conversion on text files. + + basepath: + Instructs the unpack stage to strip the specified + directories from the source path when unpacking. + + subdir: + Unpacks the specific URL to the specified subdirectory + within the root directory. + + + The unpack call automatically decompresses and extracts files + with ".Z", ".z", ".gz", ".xz", ".zip", ".jar", ".ipk", ".rpm". + ".srpm", ".deb" and ".bz2" extensions as well as various combinations + of tarball extensions. + + + + As mentioned, the Git fetcher has its own unpack method that + is optimized to work with Git trees. + Basically, this method works by cloning the tree into the final + directory. + The process is completed using references so that there is + only one central copy of the Git metadata needed. + +
+ +
+ Fetchers + + + As mentioned earlier, the URL prefix determines which + fetcher submodule BitBake uses. + Each submodule can support different URL parameters, + which are described in the following sections. + + +
+ Local file fetcher (<filename>file://</filename>) + + + This submodule handles URLs that begin with + file://. + The filename you specify within the URL can be + either an absolute or relative path to a file. + If the filename is relative, the contents of the + FILESPATH + variable is used in the same way + PATH is used to find executables. + If the file cannot be found, it is assumed that it is available in + DL_DIR + by the time the download() method is called. + + + + If you specify a directory, the entire directory is + unpacked. + + + + Here are a couple of example URLs, the first relative and + the second absolute: + + SRC_URI = "file://relativefile.patch" + SRC_URI = "file:///Users/ich/very_important_software" + + +

+ HTTP/FTP wget fetcher (<filename>http://</filename>, <filename>ftp://</filename>, <filename>https://</filename>) + + + This fetcher obtains files from web and FTP servers. + Internally, the fetcher uses the wget utility. + + + + The executable and parameters used are specified by the + FETCHCMD_wget variable, which defaults + to sensible values. + The fetcher supports a parameter "downloadfilename" that + allows the name of the downloaded file to be specified. + Specifying the name of the downloaded file is useful + for avoiding collisions in + DL_DIR + when dealing with multiple files that have the same name. + + + + Some example URLs are as follows: + + SRC_URI = "http://oe.handhelds.org/not_there.aac" + SRC_URI = "ftp://oe.handhelds.org/not_there_as_well.aac" + SRC_URI = "ftp://you@oe.handhelds.org/home/you/secret.plan" + + + + Because URL parameters are delimited by semi-colons, this can + introduce ambiguity when parsing URLs that also contain semi-colons, + for example: + + SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git;a=snapshot;h=a5dd47" + + Such URLs should should be modified by replacing semi-colons with '&' characters: + + SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&a=snapshot&h=a5dd47" + + In most cases this should work. Treating semi-colons and '&' in queries + identically is recommended by the World Wide Web Consortium (W3C). + Note that due to the nature of the URL, you may have to specify the name + of the downloaded file as well: + + SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&a=snapshot&h=a5dd47;downloadfilename=myfile.bz2" + + +
+ +
+ CVS fetcher (<filename>(cvs://</filename>) + + + This submodule handles checking out files from the + CVS version control system. + You can configure it using a number of different variables: + + FETCHCMD_cvs: + The name of the executable to use when running + the cvs command. + This name is usually "cvs". + + SRCDATE: + The date to use when fetching the CVS source code. + A special value of "now" causes the checkout to + be updated on every build. + + CVSDIR: + Specifies where a temporary checkout is saved. + The location is often DL_DIR/cvs. + + CVS_PROXY_HOST: + The name to use as a "proxy=" parameter to the + cvs command. + + CVS_PROXY_PORT: + The port number to use as a "proxyport=" parameter to + the cvs command. + + + As well as the standard username and password URL syntax, + you can also configure the fetcher with various URL parameters: + + + + The supported parameters are as follows: + + "method": + The protocol over which to communicate with the CVS + server. + By default, this protocol is "pserver". + If "method" is set to "ext", BitBake examines the + "rsh" parameter and sets CVS_RSH. + You can use "dir" for local directories. + + "module": + Specifies the module to check out. + You must supply this parameter. + + "tag": + Describes which CVS TAG should be used for + the checkout. + By default, the TAG is empty. + + "date": + Specifies a date. + If no "date" is specified, the + SRCDATE + of the configuration is used to checkout a specific date. + The special value of "now" causes the checkout to be + updated on every build. + + "localdir": + Used to rename the module. + Effectively, you are renaming the output directory + to which the module is unpacked. + You are forcing the module into a special + directory relative to + CVSDIR. + + "rsh" + Used in conjunction with the "method" parameter. + + "scmdata": + Causes the CVS metadata to be maintained in the tarball + the fetcher creates when set to "keep". + The tarball is expanded into the work directory. + By default, the CVS metadata is removed. + + "fullpath": + Controls whether the resulting checkout is at the + module level, which is the default, or is at deeper + paths. + + "norecurse": + Causes the fetcher to only checkout the specified + directory with no recurse into any subdirectories. + + "port": + The port to which the CVS server connects. + + + Some example URLs are as follows: + + SRC_URI = "cvs://CVSROOT;module=mymodule;tag=some-version;method=ext" + SRC_URI = "cvs://CVSROOT;module=mymodule;date=20060126;localdir=usethat" + + +
+ +
+ Subversion (SVN) Fetcher (<filename>svn://</filename>) + + + This fetcher submodule fetches code from the + Subversion source control system. + The executable used is specified by + FETCHCMD_svn, which defaults + to "svn". + The fetcher's temporary working directory is set by + SVNDIR, + which is usually DL_DIR/svn. + + + + The supported parameters are as follows: + + "module": + The name of the svn module to checkout. + You must provide this parameter. + You can think of this parameter as the top-level + directory of the repository data you want. + + "path_spec": + A specific directory in which to checkout the + specified svn module. + + "protocol": + The protocol to use, which defaults to "svn". + If "protocol" is set to "svn+ssh", the "ssh" + parameter is also used. + + "rev": + The revision of the source code to checkout. + + "scmdata": + Causes the “.svn†directories to be available during + compile-time when set to "keep". + By default, these directories are removed. + + "ssh": + An optional parameter used when "protocol" is set + to "svn+ssh". + You can use this parameter to specify the ssh + program used by svn. + + "transportuser": + When required, sets the username for the transport. + By default, this parameter is empty. + The transport username is different than the username + used in the main URL, which is passed to the subversion + command. + + + Following are three examples using svn: + + SRC_URI = "svn://myrepos/proj1;module=vip;protocol=http;rev=667" + SRC_URI = "svn://myrepos/proj1;module=opie;protocol=svn+ssh" + SRC_URI = "svn://myrepos/proj1;module=trunk;protocol=http;path_spec=${MY_DIR}/proj1" + + +
+ +
+ Git Fetcher (<filename>git://</filename>) + + + This fetcher submodule fetches code from the Git + source control system. + The fetcher works by creating a bare clone of the + remote into + GITDIR, + which is usually DL_DIR/git2. + This bare clone is then cloned into the work directory during the + unpack stage when a specific tree is checked out. + This is done using alternates and by reference to + minimize the amount of duplicate data on the disk and + make the unpack process fast. + The executable used can be set with + FETCHCMD_git. + + + + This fetcher supports the following parameters: + + "protocol": + The protocol used to fetch the files. + The default is "git" when a hostname is set. + If a hostname is not set, the Git protocol is "file". + You can also use "http", "https", "ssh" and "rsync". + + "nocheckout": + Tells the fetcher to not checkout source code when + unpacking when set to "1". + Set this option for the URL where there is a custom + routine to checkout code. + The default is "0". + + "rebaseable": + Indicates that the upstream Git repository can be rebased. + You should set this parameter to "1" if + revisions can become detached from branches. + In this case, the source mirror tarball is done per + revision, which has a loss of efficiency. + Rebasing the upstream Git repository could cause the + current revision to disappear from the upstream repository. + This option reminds the fetcher to preserve the local cache + carefully for future use. + The default value for this parameter is "0". + + "nobranch": + Tells the fetcher to not check the SHA validation + for the branch when set to "1". + The default is "0". + Set this option for the recipe that refers to + the commit that is valid for a tag instead of + the branch. + + "bareclone": + Tells the fetcher to clone a bare clone into the + destination directory without checking out a working tree. + Only the raw Git metadata is provided. + This parameter implies the "nocheckout" parameter as well. + + "branch": + The branch(es) of the Git tree to clone. + If unset, this is assumed to be "master". + The number of branch parameters much match the number of + name parameters. + + "rev": + The revision to use for the checkout. + The default is "master". + + "tag": + Specifies a tag to use for the checkout. + To correctly resolve tags, BitBake must access the + network. + For that reason, tags are often not used. + As far as Git is concerned, the "tag" parameter behaves + effectively the same as the "rev" parameter. + + "subpath": + Limits the checkout to a specific subpath of the tree. + By default, the whole tree is checked out. + + "destsuffix": + The name of the path in which to place the checkout. + By default, the path is git/. + + + Here are some example URLs: + + SRC_URI = "git://git.oe.handhelds.org/git/vip.git;tag=version-1" + SRC_URI = "git://git.oe.handhelds.org/git/vip.git;protocol=http" + + +
+ +
+ Git Submodule Fetcher (<filename>gitsm://</filename>) + + + This fetcher submodule inherits from the + Git fetcher and extends + that fetcher's behavior by fetching a repository's submodules. + SRC_URI + is passed to the Git fetcher as described in the + "Git Fetcher (git://)" + section. + + Notes and Warnings + + You must clean a recipe when switching between + 'git://' and + 'gitsm://' URLs. + + + + The Git Submodules fetcher is not a complete fetcher + implementation. + The fetcher has known issues where it does not use the + normal source mirroring infrastructure properly. Further, + the submodule sources it fetches are not visible to the + licensing and source archiving infrastructures. + + + +
+ +
+ ClearCase Fetcher (<filename>ccrc://</filename>) + + + This fetcher submodule fetches code from a + ClearCase + repository. + + + + To use this fetcher, make sure your recipe has proper + SRC_URI, + SRCREV, and + PV settings. + Here is an example: + + SRC_URI = "ccrc://cc.example.org/ccrc;vob=/example_vob;module=/example_module" + SRCREV = "EXAMPLE_CLEARCASE_TAG" + PV = "${@d.getVar("SRCREV", False).replace("/", "+")}" + + The fetcher uses the rcleartool or + cleartool remote client, depending on + which one is available. + + + + Following are options for the SRC_URI + statement: + + vob: + The name, which must include the + prepending "/" character, of the ClearCase VOB. + This option is required. + + module: + The module, which must include the + prepending "/" character, in the selected VOB. + + The module and vob + options are combined to create the load rule in + the view config spec. + As an example, consider the vob and + module values from the + SRC_URI statement at the start of this section. + Combining those values results in the following: + + load /example_vob/example_module + + + + proto: + The protocol, which can be either http or + https. + + + + + + By default, the fetcher creates a configuration specification. + If you want this specification written to an area other than the default, + use the CCASE_CUSTOM_CONFIG_SPEC variable + in your recipe to define where the specification is written. + + the SRCREV loses its functionality if you + specify this variable. + However, SRCREV is still used to label the + archive after a fetch even though it does not define what is + fetched. + + + + + Here are a couple of other behaviors worth mentioning: + + + When using cleartool, the login of + cleartool is handled by the system. + The login require no special steps. + + + In order to use rcleartool with authenticated + users, an "rcleartool login" is necessary before using the fetcher. + + + +
+ +
+ Perforce Fetcher (<filename>p4://</filename>) + + + This fetcher submodule fetches code from the + Perforce + source control system. + The executable used is specified by + FETCHCMD_p4, which defaults + to "p4". + The fetcher's temporary working directory is set by + P4DIR, + which defaults to "DL_DIR/p4". + + + + To use this fetcher, make sure your recipe has proper + SRC_URI, + SRCREV, and + PV values. + The p4 executable is able to use the config file defined by your + system's P4CONFIG environment variable in + order to define the Perforce server URL and port, username, and + password if you do not wish to keep those values in a recipe + itself. + If you choose not to use P4CONFIG, + or to explicitly set variables that P4CONFIG + can contain, you can specify the P4PORT value, + which is the server's URL and port number, and you can + specify a username and password directly in your recipe within + SRC_URI. + + + + Here is an example that relies on P4CONFIG + to specify the server URL and port, username, and password, and + fetches the Head Revision: + + SRC_URI = "p4://example-depot/main/source/..." + SRCREV = "${AUTOREV}" + PV = "p4-${SRCPV}" + S = "${WORKDIR}/p4" + + + + + Here is an example that specifies the server URL and port, + username, and password, and fetches a Revision based on a Label: + + P4PORT = "tcp:p4server.example.net:1666" + SRC_URI = "p4://user:passwd@example-depot/main/source/..." + SRCREV = "release-1.0" + PV = "p4-${SRCPV}" + S = "${WORKDIR}/p4" + + + You should always set S + to "${WORKDIR}/p4" in your recipe. + + +
+ +
+ Repo Fetcher (<filename>repo://</filename>) + + + This fetcher submodule fetches code from + google-repo source control system. + The fetcher works by initiating and syncing sources of the + repository into + REPODIR, + which is usually + DL_DIR/repo. + + + + This fetcher supports the following parameters: + + + "protocol": + Protocol to fetch the repository manifest (default: git). + + + "branch": + Branch or tag of repository to get (default: master). + + + "manifest": + Name of the manifest file (default: default.xml). + + + Here are some example URLs: + + SRC_URI = "repo://REPOROOT;protocol=git;branch=some_branch;manifest=my_manifest.xml" + SRC_URI = "repo://REPOROOT;protocol=file;branch=some_branch;manifest=my_manifest.xml" + + +

+ Setting Up the BitBake Environment + + + First, you need to be sure that you can run BitBake. + Set your working directory to where your local BitBake + files are and run the following command: + + $ ./bin/bitbake --version + BitBake Build Tool Core version 1.23.0, bitbake version 1.23.0 + + The console output tells you what version you are running. + + + + The recommended method to run BitBake is from a directory of your + choice. + To be able to run BitBake from any directory, you need to add the + executable binary to your binary to your shell's environment + PATH variable. + First, look at your current PATH variable + by entering the following: + + $ echo $PATH + + Next, add the directory location for the BitBake binary to the + PATH. + Here is an example that adds the + /home/scott-lenovo/bitbake/bin directory + to the front of the PATH variable: + + $ export PATH=/home/scott-lenovo/bitbake/bin:$PATH + + You should now be able to enter the bitbake + command from the command line while working from any directory. + +
+ +
+ The Hello World Example + + + The overall goal of this exercise is to build a + complete "Hello World" example utilizing task and layer + concepts. + Because this is how modern projects such as OpenEmbedded and + the Yocto Project utilize BitBake, the example + provides an excellent starting point for understanding + BitBake. + + + + To help you understand how to use BitBake to build targets, + the example starts with nothing but the bitbake + command, which causes BitBake to fail and report problems. + The example progresses by adding pieces to the build to + eventually conclude with a working, minimal "Hello World" + example. + + + + While every attempt is made to explain what is happening during + the example, the descriptions cannot cover everything. + You can find further information throughout this manual. + Also, you can actively participate in the + + discussion mailing list about the BitBake build tool. + + + + This example was inspired by and drew heavily from + Mailing List post - The BitBake equivalent of "Hello, World!". + + + + As stated earlier, the goal of this example + is to eventually compile "Hello World". + However, it is unknown what BitBake needs and what you have + to provide in order to achieve that goal. + Recall that BitBake utilizes three types of metadata files: + Configuration Files, + Classes, and + Recipes. + But where do they go? + How does BitBake find them? + BitBake's error messaging helps you answer these types of questions + and helps you better understand exactly what is going on. + + + + Following is the complete "Hello World" example. + + + + Create a Project Directory: + First, set up a directory for the "Hello World" project. + Here is how you can do so in your home directory: + + $ mkdir ~/hello + $ cd ~/hello + + This is the directory that BitBake will use to do all of + its work. + You can use this directory to keep all the metafiles needed + by BitBake. + Having a project directory is a good way to isolate your + project. + + Run Bitbake: + At this point, you have nothing but a project directory. + Run the bitbake command and see what + it does: + + $ bitbake + The BBPATH variable is not set and bitbake did not + find a conf/bblayers.conf file in the expected location. + Maybe you accidentally invoked bitbake from the wrong directory?

+ Introduction + + + Fundamentally, BitBake is a generic task execution + engine that allows shell and Python tasks to be run + efficiently and in parallel while working within + complex inter-task dependency constraints. + One of BitBake's main users, OpenEmbedded, takes this core + and builds embedded Linux software stacks using + a task-oriented approach. + + + + Conceptually, BitBake is similar to GNU Make in + some regards but has significant differences: + + + BitBake executes tasks according to provided + metadata that builds up the tasks. + Metadata is stored in recipe (.bb) + and related recipe "append" (.bbappend) + files, configuration (.conf) and + underlying include (.inc) files, and + in class (.bbclass) files. + The metadata provides + BitBake with instructions on what tasks to run and + the dependencies between those tasks. + + + BitBake includes a fetcher library for obtaining source + code from various places such as local files, source control + systems, or websites. + + + The instructions for each unit to be built (e.g. a piece + of software) are known as "recipe" files and + contain all the information about the unit + (dependencies, source file locations, checksums, description + and so on). + + + BitBake includes a client/server abstraction and can + be used from a command line or used as a service over + XML-RPC and has several different user interfaces. + + + +
+ +
+ History and Goals + + + BitBake was originally a part of the OpenEmbedded project. + It was inspired by the Portage package management system + used by the Gentoo Linux distribution. + On December 7, 2004, OpenEmbedded project team member + Chris Larson split the project into two distinct pieces: + + BitBake, a generic task executor + OpenEmbedded, a metadata set utilized by + BitBake + + Today, BitBake is the primary basis of the + OpenEmbedded + project, which is being used to build and maintain Linux + distributions such as the + Angstrom Distribution, + and which is also being used as the build tool for Linux projects + such as the + Yocto Project. + + + + Prior to BitBake, no other build tool adequately met the needs of + an aspiring embedded Linux distribution. + All of the build systems used by traditional desktop Linux + distributions lacked important functionality, and none of the + ad hoc Buildroot-based systems, prevalent in the + embedded space, were scalable or maintainable. + + + + Some important original goals for BitBake were: + + + Handle cross-compilation. + + + Handle inter-package dependencies (build time on + target architecture, build time on native + architecture, and runtime). + + + Support running any number of tasks within a given + package, including, but not limited to, fetching + upstream sources, unpacking them, patching them, + configuring them, and so forth. + + + Be Linux distribution agnostic for both build and + target systems. + + + Be architecture agnostic. + + + Support multiple build and target operating systems + (e.g. Cygwin, the BSDs, and so forth). + + + Be self contained, rather than tightly + integrated into the build machine's root + filesystem. + + + Handle conditional metadata on the target architecture, + operating system, distribution, and machine. + + + Be easy to use the tools to supply local metadata and packages + against which to operate. + + + Be easy to use BitBake to collaborate between multiple + projects for their builds. + + + Provide an inheritance mechanism to share + common metadata between many packages. + + + Over time it became apparent that some further requirements + were necessary: + + + Handle variants of a base recipe (e.g. native, sdk, + and multilib). + + + Split metadata into layers and allow layers + to enhance or override other layers. + + + Allow representation of a given set of input variables + to a task as a checksum. + Based on that checksum, allow acceleration of builds + with prebuilt components. + + + BitBake satisfies all the original requirements and many more + with extensions being made to the basic functionality to + reflect the additional requirements. + Flexibility and power have always been the priorities. + BitBake is highly extensible and supports embedded Python code and + execution of any arbitrary tasks. + +
+ +
+ Concepts + + + BitBake is a program written in the Python language. + At the highest level, BitBake interprets metadata, decides + what tasks are required to run, and executes those tasks. + Similar to GNU Make, BitBake controls how software is + built. + GNU Make achieves its control through "makefiles", while + BitBake uses "recipes". + + + + BitBake extends the capabilities of a simple + tool like GNU Make by allowing for the definition of much more + complex tasks, such as assembling entire embedded Linux + distributions. + + + + The remainder of this section introduces several concepts + that should be understood in order to better leverage + the power of BitBake. + + +
+ Recipes + + + BitBake Recipes, which are denoted by the file extension + .bb, are the most basic metadata files. + These recipe files provide BitBake with the following: + + Descriptive information about the + package (author, homepage, license, and so on) + The version of the recipe + Existing dependencies (both build + and runtime dependencies) + Where the source code resides and + how to fetch it + Whether the source code requires + any patches, where to find them, and how to apply + them + How to configure and compile the + source code + Where on the target machine to install the + package or packages created + + + + + Within the context of BitBake, or any project utilizing BitBake + as its build system, files with the .bb + extension are referred to as recipes. + + The term "package" is also commonly used to describe recipes. + However, since the same word is used to describe packaged + output from a project, it is best to maintain a single + descriptive term - "recipes". + Put another way, a single "recipe" file is quite capable + of generating a number of related but separately installable + "packages". + In fact, that ability is fairly common. + + +
+ +
+ Configuration Files + + + Configuration files, which are denoted by the + .conf extension, define + various configuration variables that govern the project's build + process. + These files fall into several areas that define + machine configuration options, distribution configuration + options, compiler tuning options, general common + configuration options, and user configuration options. + The main configuration file is the sample + bitbake.conf file, which is + located within the BitBake source tree + conf directory. + +
+ +
+ Classes + + + Class files, which are denoted by the + .bbclass extension, contain + information that is useful to share between metadata files. + The BitBake source tree currently comes with one class metadata file + called base.bbclass. + You can find this file in the + classes directory. + The base.bbclass class files is special since it + is always included automatically for all recipes + and classes. + This class contains definitions for standard basic tasks such + as fetching, unpacking, configuring (empty by default), + compiling (runs any Makefile present), installing (empty by + default) and packaging (empty by default). + These tasks are often overridden or extended by other classes + added during the project development process. + +
+ +
+ Layers + + + Layers allow you to isolate different types of + customizations from each other. + While you might find it tempting to keep everything in one layer + when working on a single project, the more modular you organize + your metadata, the easier it is to cope with future changes. + + + + To illustrate how you can use layers to keep things modular, + consider customizations you might make to support a specific target machine. + These types of customizations typically reside in a special layer, + rather than a general layer, called a Board Support Package (BSP) + Layer. + Furthermore, the machine customizations should be isolated from + recipes and metadata that support a new GUI environment, for + example. + This situation gives you a couple of layers: one for the machine + configurations and one for the GUI environment. + It is important to understand, however, that the BSP layer can still + make machine-specific additions to recipes within + the GUI environment layer without polluting the GUI layer itself + with those machine-specific changes. + You can accomplish this through a recipe that is a BitBake append + (.bbappend) file. + +
+ +
+ Append Files + + + Append files, which are files that have the + .bbappend file extension, extend or + override information in an existing recipe file. + + + + BitBake expects every append file to have a corresponding recipe file. + Furthermore, the append file and corresponding recipe file + must use the same root filename. + The filenames can differ only in the file type suffix used + (e.g. formfactor_0.0.bb and + formfactor_0.0.bbappend). + + + + Information in append files extends or + overrides the information in the underlying, + similarly-named recipe files. + + + + When you name an append file, you can use the + wildcard character (%) to allow for matching recipe names. + For example, suppose you have an append file named + as follows: + + busybox_1.21.%.bbappend + + That append file would match any busybox_1.21.x.bb + version of the recipe. + So, the append file would match the following recipe names: + + busybox_1.21.1.bb + busybox_1.21.2.bb + busybox_1.21.3.bb + + If the busybox recipe was updated to + busybox_1.3.0.bb, the append name would not + match. + However, if you named the append file + busybox_1.%.bbappend, then you would have a match. + + + + In the most general case, you could name the append file something as + simple as busybox_%.bbappend to be entirely + version independent. + +
+
+ +
+ Obtaining BitBake + + + You can obtain BitBake several different ways: + + Cloning BitBake: + Using Git to clone the BitBake source code repository + is the recommended method for obtaining BitBake. + Cloning the repository makes it easy to get bug fixes + and have access to stable branches and the master + branch. + Once you have cloned BitBake, you should use + the latest stable + branch for development since the master branch is for + BitBake development and might contain less stable changes. + + You usually need a version of BitBake + that matches the metadata you are using. + The metadata is generally backwards compatible but + not forward compatible. + Here is an example that clones the BitBake repository: + + $ git clone git://git.openembedded.org/bitbake + + This command clones the BitBake Git repository into a + directory called bitbake. + Alternatively, you can + designate a directory after the + git clone command + if you want to call the new directory something + other than bitbake. + Here is an example that names the directory + bbdev: + + $ git clone git://git.openembedded.org/bitbake bbdev + + Installation using your Distribution + Package Management System: + This method is not + recommended because the BitBake version that is + provided by your distribution, in most cases, + is several + releases behind a snapshot of the BitBake repository. + + Taking a snapshot of BitBake: + Downloading a snapshot of BitBake from the + source code repository gives you access to a known + branch or release of BitBake. + + Cloning the Git repository, as described earlier, + is the preferred method for getting BitBake. + Cloning the repository makes it easier to update as + patches are added to the stable branches. + + The following example downloads a snapshot of + BitBake version 1.17.0: + + $ wget http://git.openembedded.org/bitbake/snapshot/bitbake-1.17.0.tar.gz + $ tar zxpvf bitbake-1.17.0.tar.gz + + After extraction of the tarball using the tar utility, + you have a directory entitled + bitbake-1.17.0. + + Using the BitBake that Comes With Your + Build Checkout: + A final possibility for getting a copy of BitBake is that it + already comes with your checkout of a larger Bitbake-based build + system, such as Poky. + Rather than manually checking out individual layers and + gluing them together yourself, you can check + out an entire build system. + The checkout will already include a version of BitBake that + has been thoroughly tested for compatibility with the other + components. + For information on how to check out a particular BitBake-based + build system, consult that build system's supporting documentation. + + + +
+ +
+ The BitBake Command + + + The bitbake command is the primary interface + to the BitBake tool. + This section presents the BitBake command syntax and provides + several execution examples. + + +
+ Usage and syntax + + + Following is the usage and syntax for BitBake: + + $ bitbake -h + Usage: bitbake [options] [recipename/target recipe:do_task ...] + + Executes the specified task (default is 'build') for a given set of target recipes (.bb files). + It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which + will provide the layer, BBFILES and other configuration information. + + Options: + --version show program's version number and exit + -h, --help show this help message and exit + -b BUILDFILE, --buildfile=BUILDFILE + Execute tasks from a specific .bb recipe directly. + WARNING: Does not handle any dependencies from other + recipes. + -k, --continue Continue as much as possible after an error.

The exact options + available depend on the metadata. Some examples might + be 'compile' or 'populate_sysroot' or 'listtasks' may + give a list of the tasks available. + -C INVALIDATE_STAMP, --clear-stamp=INVALIDATE_STAMP + Invalidate the stamp for the specified task such as + 'compile' and then run the default task for the + specified target(s). + -r PREFILE, --read=PREFILE + Read the specified file before bitbake.conf. + -R POSTFILE, --postread=POSTFILE + Read the specified file after bitbake.conf. + -v, --verbose Enable tracing of shell tasks (with 'set -x'). Also + print bb.note(...) messages to stdout (in addition to + writing them to ${T}/log.do_<task>). + -D, --debug Increase the debug level. You can specify this more + than once. -D sets the debug level to 1, where only + bb.debug(1, ...) messages are printed to stdout; -DD + sets the debug level to 2, where both bb.debug(1, ...) + and bb.debug(2, ...) messages are printed; etc. + Without -D, no debug messages are printed. Note that + -D only affects output to stdout. All debug messages + are written to ${T}/log.do_taskname, regardless of the + debug level. + -q, --quiet Output less log message data to the terminal. You can + specify this more than once. + -n, --dry-run Don't execute, just go through the motions. + -S SIGNATURE_HANDLER, --dump-signatures=SIGNATURE_HANDLER + Dump out the signature construction information, with + no task execution. The SIGNATURE_HANDLER parameter is + passed to the handler. Two common values are none and + printdiff but the handler may define more/less. none + means only dump the signature, printdiff means compare + the dumped signature with the cached one. + -p, --parse-only Quit after parsing the BB recipes. + -s, --show-versions Show current and preferred versions of all recipes. + -e, --environment Show the global or per-recipe environment complete + with information about where variables were + set/changed. + -g, --graphviz Save dependency tree information for the specified + targets in the dot syntax. + -I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED + Assume these dependencies don't exist and are already + provided (equivalent to ASSUME_PROVIDED). Useful to + make dependency graphs more appealing + -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS + Show debug logging for the specified logging domains + -P, --profile Profile the command and save reports. + -u UI, --ui=UI The user interface to use (knotty, ncurses or taskexp + - default knotty). + --token=XMLRPCTOKEN Specify the connection token to be used when + connecting to a remote server. + --revisions-changed Set the exit code depending on whether upstream + floating revisions have changed or not. + --server-only Run bitbake without a UI, only starting a server + (cooker) process. + -B BIND, --bind=BIND The name/address for the bitbake xmlrpc server to bind + to. + -T SERVER_TIMEOUT, --idle-timeout=SERVER_TIMEOUT + Set timeout to unload bitbake server due to + inactivity, set to -1 means no unload, default: + Environment variable BB_SERVER_TIMEOUT. + --no-setscene Do not run any setscene tasks. sstate will be ignored + and everything needed, built. + --setscene-only Only run setscene tasks, don't run any real tasks. + --remote-server=REMOTE_SERVER + Connect to the specified server. + -m, --kill-server Terminate any running bitbake server. + --observe-only Connect to a server as an observing-only client. + --status-only Check the status of the remote bitbake server. + -w WRITEEVENTLOG, --write-log=WRITEEVENTLOG + Writes the event log of the build to a bitbake event + json file. Use '' (empty string) to assign the name + automatically. + --runall=RUNALL Run the specified task for any recipe in the taskgraph + of the specified target (even if it wouldn't otherwise + have run). + --runonly=RUNONLY Run only the specified task within the taskgraph of + the specified targets (and any task dependencies those + tasks may have). + + +
+ +
+ Examples + + + This section presents some examples showing how to use BitBake. + + +
+ Executing a Task Against a Single Recipe + + + Executing tasks for a single recipe file is relatively simple. + You specify the file in question, and BitBake parses + it and executes the specified task. + If you do not specify a task, BitBake executes the default + task, which is "buildâ€. + BitBake obeys inter-task dependencies when doing + so. + + + + The following command runs the build task, which is + the default task, on the foo_1.0.bb + recipe file: + + $ bitbake -b foo_1.0.bb + + The following command runs the clean task on the + foo.bb recipe file: + + $ bitbake -b foo.bb -c clean + + + The "-b" option explicitly does not handle recipe + dependencies. + Other than for debugging purposes, it is instead + recommended that you use the syntax presented in the + next section. + + +
+ +
+ Executing Tasks Against a Set of Recipe Files + + + There are a number of additional complexities introduced + when one wants to manage multiple .bb + files. + Clearly there needs to be a way to tell BitBake what + files are available and, of those, which you + want to execute. + There also needs to be a way for each recipe + to express its dependencies, both for build-time and + runtime. + There must be a way for you to express recipe preferences + when multiple recipes provide the same functionality, or when + there are multiple versions of a recipe. + + + + The bitbake command, when not using + "--buildfile" or "-b" only accepts a "PROVIDES". + You cannot provide anything else. + By default, a recipe file generally "PROVIDES" its + "packagename" as shown in the following example: + + $ bitbake foo + + This next example "PROVIDES" the package name and also uses + the "-c" option to tell BitBake to just execute the + do_clean task: + + $ bitbake -c clean foo + + +
+ +
+ Executing a List of Task and Recipe Combinations + + + The BitBake command line supports specifying different + tasks for individual targets when you specify multiple + targets. + For example, suppose you had two targets (or recipes) + myfirstrecipe and + mysecondrecipe and you needed + BitBake to run taskA for the first + recipe and taskB for the second + recipe: + + $ bitbake myfirstrecipe:do_taskA mysecondrecipe:do_taskB + + +
+ +
+ Generating Dependency Graphs + + + BitBake is able to generate dependency graphs using + the dot syntax. + You can convert these graphs into images using the + dot tool from + Graphviz. + + + + When you generate a dependency graph, BitBake writes three files + to the current working directory: + + + recipe-depends.dot: + Shows dependencies between recipes (i.e. a collapsed version of + task-depends.dot). + + + task-depends.dot: + Shows dependencies between tasks. + These dependencies match BitBake's internal task execution list. + + + pn-buildlist: + Shows a simple list of targets that are to be built. + + + + + + To stop depending on common depends, use the "-I" depend + option and BitBake omits them from the graph. + Leaving this information out can produce more readable graphs. + This way, you can remove from the graph + DEPENDS from inherited classes + such as base.bbclass. + + + + Here are two examples that create dependency graphs. + The second example omits depends common in OpenEmbedded from + the graph: + + $ bitbake -g foo + + $ bitbake -g -I virtual/kernel -I eglibc foo + + +

+ Basic Syntax + + + This section provides some basic syntax examples. + + +
+ Basic Variable Setting + + + The following example sets VARIABLE to + "value". + This assignment occurs immediately as the statement is parsed. + It is a "hard" assignment. + + VARIABLE = "value" + + As expected, if you include leading or trailing spaces as part of + an assignment, the spaces are retained: + + VARIABLE = " value" + VARIABLE = "value " + + Setting VARIABLE to "" sets it to an empty string, + while setting the variable to " " sets it to a blank space + (i.e. these are not the same values). + + VARIABLE = "" + VARIABLE = " " + + + + + You can use single quotes instead of double quotes + when setting a variable's value. + Doing so allows you to use values that contain the double + quote character: + + VARIABLE = 'I have a " in my value' + + + Unlike in Bourne shells, single quotes work identically + to double quotes in all other ways. + They do not suppress variable expansions. + + +
+ +
+ Line Joining + + + Outside of + functions, BitBake joins + any line ending in a backslash character ("\") + with the following line before parsing statements. + The most common use for the "\" character is to split variable + assignments over multiple lines, as in the following example: + + FOO = "bar \ + baz \ + qaz" + + Both the "\" character and the newline character + that follow it are removed when joining lines. + Thus, no newline characters end up in the value of + FOO. + + + + Consider this additional example where the two + assignments both assign "barbaz" to + FOO: + + FOO = "barbaz" + + FOO = "bar\ + baz" + + + BitBake does not interpret escape sequences like + "\n" in variable values. + For these to have an effect, the value must be passed + to some utility that interprets escape sequences, + such as printf or + echo -n. + + +
+ +
+ Variable Expansion + + + Variables can reference the contents of other variables + using a syntax that is similar to variable expansion in + Bourne shells. + The following assignments + result in A containing "aval" and B evaluating to "preavalpost". + + A = "aval" + B = "pre${A}post" + + + Unlike in Bourne shells, the curly braces are mandatory: + Only ${FOO} and not + $FOO is recognized as an expansion of + FOO. + + The "=" operator does not immediately expand variable + references in the right-hand side. + Instead, expansion is deferred until the variable assigned to + is actually used. + The result depends on the current values of the referenced + variables. + The following example should clarify this behavior: + + A = "${B} baz" + B = "${C} bar" + C = "foo" + *At this point, ${A} equals "foo bar baz"* + C = "qux" + *At this point, ${A} equals "qux bar baz"* + B = "norf" + *At this point, ${A} equals "norf baz"* + + Contrast this behavior with the + immediate variable expansion + operator (i.e. ":="). + + + + If the variable expansion syntax is used on a variable that + does not exist, the string is kept as is. + For example, given the following assignment, + BAR expands to the literal string + "${FOO}" as long as FOO does not exist. + + BAR = "${FOO}" + + +
+ +
+ Setting a default value (?=) + + + You can use the "?=" operator to achieve a "softer" assignment + for a variable. + This type of assignment allows you to define a variable if it + is undefined when the statement is parsed, but to leave the + value alone if the variable has a value. + Here is an example: + + A ?= "aval" + + If A is set at the time this statement is parsed, + the variable retains its value. + However, if A is not set, + the variable is set to "aval". + + This assignment is immediate. + Consequently, if multiple "?=" assignments + to a single variable exist, the first of those ends up getting + used. + + +
+ +
+ Setting a weak default value (??=) + + + It is possible to use a "weaker" assignment than in the + previous section by using the "??=" operator. + This assignment behaves identical to "?=" except that the + assignment is made at the end of the parsing process rather + than immediately. + Consequently, when multiple "??=" assignments exist, the last + one is used. + Also, any "=" or "?=" assignment will override the value set with + "??=". + Here is an example: + + A ??= "somevalue" + A ??= "someothervalue" + + If A is set before the above statements are parsed, + the variable retains its value. + If A is not set, + the variable is set to "someothervalue". + + + + Again, this assignment is a "lazy" or "weak" assignment + because it does not occur until the end + of the parsing process. + +
+ +
+ Immediate variable expansion (:=) + + + The ":=" operator results in a variable's + contents being expanded immediately, + rather than when the variable is actually used: + + T = "123" + A := "${B} ${A} test ${T}" + T = "456" + B = "${T} bval" + C = "cval" + C := "${C}append" + + In this example, A contains + "test 123" because ${B} and + ${A} at the time of parsing are undefined, + which leaves "test 123". + And, the variable C + contains "cvalappend" since ${C} immediately + expands to "cval". + +
+ +
+ Appending (+=) and prepending (=+) With Spaces + + + Appending and prepending values is common and can be accomplished + using the "+=" and "=+" operators. + These operators insert a space between the current + value and prepended or appended value. + + + + These operators take immediate effect during parsing. + Here are some examples: + + B = "bval" + B += "additionaldata" + C = "cval" + C =+ "test" + + The variable B contains + "bval additionaldata" and C + contains "test cval". + +
+ +
+ Appending (.=) and Prepending (=.) Without Spaces + + + If you want to append or prepend values without an + inserted space, use the ".=" and "=." operators. + + + + These operators take immediate effect during parsing. + Here are some examples: + + B = "bval" + B .= "additionaldata" + C = "cval" + C =. "test" + + The variable B contains + "bvaladditionaldata" and + C contains "testcval". + +
+ +
+ Appending and Prepending (Override Style Syntax) + + + You can also append and prepend a variable's value + using an override style syntax. + When you use this syntax, no spaces are inserted. + + + + These operators differ from the ":=", ".=", "=.", "+=", and "=+" + operators in that their effects are deferred + until after parsing completes rather than being immediately + applied. + Here are some examples: + + B = "bval" + B_append = " additional data" + C = "cval" + C_prepend = "additional data " + D = "dval" + D_append = "additional data" + + The variable B becomes + "bval additional data" and C becomes + "additional data cval". + The variable D becomes + "dvaladditional data". + + You must control all spacing when you use the + override syntax. + + + + + It is also possible to append and prepend to shell + functions and BitBake-style Python functions. + See the + "Shell Functions" and + "BitBake-Style Python Functions + sections for examples. + +
+ +
+ Removal (Override Style Syntax) + + + You can remove values from lists using the removal + override style syntax. + Specifying a value for removal causes all occurrences of that + value to be removed from the variable. + + + + When you use this syntax, BitBake expects one or more strings. + Surrounding spaces are removed as well. + Here is an example: + + FOO = "123 456 789 123456 123 456 123 456" + FOO_remove = "123" + FOO_remove = "456" + FOO2 = "abc def ghi abcdef abc def abc def" + FOO2_remove = "abc def" + + The variable FOO becomes + "789 123456" and FOO2 becomes + "ghi abcdef". + + + + Like "_append" and "_prepend", "_remove" + is deferred until after parsing completes. + +
+ +
+ Override Style Operation Advantages + + + An advantage of the override style operations + "_append", "_prepend", and "_remove" as compared to the + "+=" and "=+" operators is that the override style + operators provide guaranteed operations. + For example, consider a class foo.bbclass + that needs to add the value "val" to the variable + FOO, and a recipe that uses + foo.bbclass as follows: + + inherit foo + + FOO = "initial" + + If foo.bbclass uses the "+=" operator, + as follows, then the final value of FOO + will be "initial", which is not what is desired: + + FOO += "val" + + If, on the other hand, foo.bbclass + uses the "_append" operator, then the final value of + FOO will be "initial val", as intended: + + FOO_append = " val" + + + It is never necessary to use "+=" together with "_append". + The following sequence of assignments appends "barbaz" to + FOO: + + FOO_append = "bar" + FOO_append = "baz" + + The only effect of changing the second assignment in the + previous example to use "+=" would be to add a space before + "baz" in the appended value (due to how the "+=" operator + works). + + Another advantage of the override style operations is that + you can combine them with other overrides as described in the + "Conditional Syntax (Overrides)" + section. + +
+ +
+ Variable Flag Syntax + + + Variable flags are BitBake's implementation of variable properties + or attributes. + It is a way of tagging extra information onto a variable. + You can find more out about variable flags in general in the + "Variable Flags" + section. + + + + You can define, append, and prepend values to variable flags. + All the standard syntax operations previously mentioned work + for variable flags except for override style syntax + (i.e. "_prepend", "_append", and "_remove"). + + + + Here are some examples showing how to set variable flags: + + FOO[a] = "abc" + FOO[b] = "123" + FOO[a] += "456" + + The variable FOO has two flags: + [a] and [b]. + The flags are immediately set to "abc" and "123", respectively. + The [a] flag becomes "abc 456". + + + + No need exists to pre-define variable flags. + You can simply start using them. + One extremely common application + is to attach some brief documentation to a BitBake variable as + follows: + + CACHE[doc] = "The directory holding the cache of the metadata." + + +
+ +
+ Inline Python Variable Expansion + + + You can use inline Python variable expansion to + set variables. + Here is an example: + + DATE = "${@time.strftime('%Y%m%d',time.gmtime())}" + + This example results in the DATE + variable being set to the current date. + + + + Probably the most common use of this feature is to extract + the value of variables from BitBake's internal data dictionary, + d. + The following lines select the values of a package name + and its version number, respectively: + + PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}" + PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}" + + + Inline Python expressions work just like variable expansions + insofar as the "=" and ":=" operators are concerned. + Given the following assignment, foo() + is called each time FOO is expanded: + + FOO = "${@foo()}" + + Contrast this with the following immediate assignment, where + foo() is only called once, while the + assignment is parsed: + + FOO := "${@foo()}" + + + For a different way to set variables with Python code during + parsing, see the + "Anonymous Python Functions" + section. + +
+ +
+ Unseting variables + + + It is possible to completely remove a variable or a variable flag + from BitBake's internal data dictionary by using the "unset" keyword. + Here is an example: + + unset DATE + unset do_fetch[noexec] + + These two statements remove the DATE and the + do_fetch[noexec] flag. + + +
+ +
+ Providing Pathnames + + + When specifying pathnames for use with BitBake, + do not use the tilde ("~") character as a shortcut + for your home directory. + Doing so might cause BitBake to not recognize the + path since BitBake does not expand this character in + the same way a shell would. + + + + Instead, provide a fuller path as the following + example illustrates: + + BBLAYERS ?= " \ + /home/scott-lenovo/LayerA \ + " + + +
+
+ +
+ Exporting Variables to the Environment + + + You can export variables to the environment of running + tasks by using the export keyword. + For example, in the following example, the + do_foo task prints "value from + the environment" when run: + + export ENV_VARIABLE + ENV_VARIABLE = "value from the environment" + + do_foo() { + bbplain "$ENV_VARIABLE" + } + + + BitBake does not expand $ENV_VARIABLE + in this case because it lacks the obligatory + {}. + Rather, $ENV_VARIABLE is expanded + by the shell. + + It does not matter whether + export ENV_VARIABLE appears before or + after assignments to ENV_VARIABLE. + + + + It is also possible to combine export + with setting a value for the variable. + Here is an example: + + export ENV_VARIABLE = "variable-value" + + In the output of bitbake -e, variables + that are exported to the environment are preceded by "export". + + + + Among the variables commonly exported to the environment + are CC and CFLAGS, + which are picked up by many build systems. + +
+ +
+ Conditional Syntax (Overrides) + + + BitBake uses + OVERRIDES + to control what variables are overridden after BitBake + parses recipes and configuration files. + This section describes how you can use + OVERRIDES as conditional metadata, + talks about key expansion in relationship to + OVERRIDES, and provides some examples + to help with understanding. + + +
+ Conditional Metadata + + + You can use OVERRIDES to conditionally select + a specific version of a variable and to conditionally + append or prepend the value of a variable. + + Overrides can only use lower-case characters. + Additionally, underscores are not permitted in override names + as they are used to separate overrides from each other and + from the variable name. + + + Selecting a Variable: + The OVERRIDES variable is + a colon-character-separated list that contains items + for which you want to satisfy conditions. + Thus, if you have a variable that is conditional on “armâ€, and “arm†+ is in OVERRIDES, then the “armâ€-specific + version of the variable is used rather than the non-conditional + version. + Here is an example: + + OVERRIDES = "architecture:os:machine" + TEST = "default" + TEST_os = "osspecific" + TEST_nooverride = "othercondvalue" + + In this example, the OVERRIDES + variable lists three overrides: + "architecture", "os", and "machine". + The variable TEST by itself has a default + value of "default". + You select the os-specific version of the TEST + variable by appending the "os" override to the variable + (i.e.TEST_os). + + + + To better understand this, consider a practical example + that assumes an OpenEmbedded metadata-based Linux + kernel recipe file. + The following lines from the recipe file first set + the kernel branch variable KBRANCH + to a default value, then conditionally override that + value based on the architecture of the build: + + KBRANCH = "standard/base" + KBRANCH_qemuarm = "standard/arm-versatile-926ejs" + KBRANCH_qemumips = "standard/mti-malta32" + KBRANCH_qemuppc = "standard/qemuppc" + KBRANCH_qemux86 = "standard/common-pc/base" + KBRANCH_qemux86-64 = "standard/common-pc-64/base" + KBRANCH_qemumips64 = "standard/mti-malta64" + + + Appending and Prepending: + BitBake also supports append and prepend operations to + variable values based on whether a specific item is + listed in OVERRIDES. + Here is an example: + + DEPENDS = "glibc ncurses" + OVERRIDES = "machine:local" + DEPENDS_append_machine = " libmad" + + In this example, DEPENDS becomes + "glibc ncurses libmad". + + + + Again, using an OpenEmbedded metadata-based + kernel recipe file as an example, the + following lines will conditionally append to the + KERNEL_FEATURES variable based + on the architecture: + + KERNEL_FEATURES_append = " ${KERNEL_EXTRA_FEATURES}" + KERNEL_FEATURES_append_qemux86=" cfg/sound.scc cfg/paravirt_kvm.scc" + KERNEL_FEATURES_append_qemux86-64=" cfg/sound.scc cfg/paravirt_kvm.scc" + + + Setting a Variable for a Single Task: + BitBake supports setting a variable just for the + duration of a single task. + Here is an example: + + FOO_task-configure = "val 1" + FOO_task-compile = "val 2" + + In the previous example, FOO + has the value "val 1" while the + do_configure task is executed, + and the value "val 2" while the + do_compile task is executed. + + + Internally, this is implemented by prepending + the task (e.g. "task-compile:") to the value of + OVERRIDES + for the local datastore of the do_compile + task. + + You can also use this syntax with other combinations + (e.g. "_prepend") as shown in the + following example: + + EXTRA_OEMAKE_prepend_task-compile = "${PARALLEL_MAKE} " + + + + +
+ +
+ Key Expansion + + + Key expansion happens when the BitBake datastore is finalized + just before BitBake expands overrides. + To better understand this, consider the following example: + + A${B} = "X" + B = "2" + A2 = "Y" + + In this case, after all the parsing is complete, and + before any overrides are handled, BitBake expands + ${B} into "2". + This expansion causes A2, which was + set to "Y" before the expansion, to become "X". + +
+ +
+ Examples + + + Despite the previous explanations that show the different forms of + variable definitions, it can be hard to work + out exactly what happens when variable operators, conditional + overrides, and unconditional overrides are combined. + This section presents some common scenarios along + with explanations for variable interactions that + typically confuse users. + + + + There is often confusion concerning the order in which + overrides and various "append" operators take effect. + Recall that an append or prepend operation using "_append" + and "_prepend" does not result in an immediate assignment + as would "+=", ".=", "=+", or "=.". + Consider the following example: + + OVERRIDES = "foo" + A = "Z" + A_foo_append = "X" + + For this case, A is + unconditionally set to "Z" and "X" is + unconditionally and immediately appended to the variable + A_foo. + Because overrides have not been applied yet, + A_foo is set to "X" due to the append + and A simply equals "Z". + + + + Applying overrides, however, changes things. + Since "foo" is listed in OVERRIDES, + the conditional variable A is replaced + with the "foo" version, which is equal to "X". + So effectively, A_foo replaces A. + + + + This next example changes the order of the override and + the append: + + OVERRIDES = "foo" + A = "Z" + A_append_foo = "X" + + For this case, before overrides are handled, + A is set to "Z" and A_append_foo + is set to "X". + Once the override for "foo" is applied, however, + A gets appended with "X". + Consequently, A becomes "ZX". + Notice that spaces are not appended. + + + + This next example has the order of the appends and overrides reversed + back as in the first example: + + OVERRIDES = "foo" + A = "Y" + A_foo_append = "Z" + A_foo_append = "X" + + For this case, before any overrides are resolved, + A is set to "Y" using an immediate assignment. + After this immediate assignment, A_foo is set + to "Z", and then further appended with + "X" leaving the variable set to "ZX". + Finally, applying the override for "foo" results in the conditional + variable A becoming "ZX" (i.e. + A is replaced with A_foo). + + + + This final example mixes in some varying operators: + + A = "1" + A_append = "2" + A_append = "3" + A += "4" + A .= "5" + + For this case, the type of append operators are affecting the + order of assignments as BitBake passes through the code + multiple times. + Initially, A is set to "1 45" because + of the three statements that use immediate operators. + After these assignments are made, BitBake applies the + "_append" operations. + Those operations result in A becoming "1 4523". + +
+
+ +
+ Sharing Functionality + + + BitBake allows for metadata sharing through include files + (.inc) and class files + (.bbclass). + For example, suppose you have a piece of common functionality + such as a task definition that you want to share between + more than one recipe. + In this case, creating a .bbclass + file that contains the common functionality and then using + the inherit directive in your recipes to + inherit the class would be a common way to share the task. + + + + This section presents the mechanisms BitBake provides to + allow you to share functionality between recipes. + Specifically, the mechanisms include include, + inherit, INHERIT, and + require directives. + + +
+ Locating Include and Class Files + + + BitBake uses the + BBPATH + variable to locate needed include and class files. + Additionally, BitBake searches the current directory for + include and require + directives. + + The BBPATH variable is analogous to + the environment variable PATH. + + + + + In order for include and class files to be found by BitBake, + they need to be located in a "classes" subdirectory that can + be found in BBPATH. + +
+ +
+ <filename>inherit</filename> Directive + + + When writing a recipe or class file, you can use the + inherit directive to inherit the + functionality of a class (.bbclass). + BitBake only supports this directive when used within recipe + and class files (i.e. .bb and + .bbclass). + + + + The inherit directive is a rudimentary + means of specifying functionality contained in class files + that your recipes require. + For example, you can easily abstract out the tasks involved in + building a package that uses Autoconf and Automake and put + those tasks into a class file and then have your recipe + inherit that class file. + + + + As an example, your recipes could use the following directive + to inherit an autotools.bbclass file. + The class file would contain common functionality for using + Autotools that could be shared across recipes: + + inherit autotools + + In this case, BitBake would search for the directory + classes/autotools.bbclass + in BBPATH. + + You can override any values and functions of the + inherited class within your recipe by doing so + after the "inherit" statement. + + If you want to use the directive to inherit + multiple classes, separate them with spaces. + The following example shows how to inherit both the + buildhistory and rm_work + classes: + + inherit buildhistory rm_work + + + + + An advantage with the inherit directive as compared to both + the + include and + require directives + is that you can inherit class files conditionally. + You can accomplish this by using a variable expression + after the inherit statement. + Here is an example: + + inherit ${VARNAME} + + If VARNAME is going to be set, it needs + to be set before the inherit statement + is parsed. + One way to achieve a conditional inherit in this case is to use + overrides: + + VARIABLE = "" + VARIABLE_someoverride = "myclass" + + + + + Another method is by using anonymous Python. + Here is an example: + + python () { + if condition == value: + d.setVar('VARIABLE', 'myclass') + else: + d.setVar('VARIABLE', '') + } + + + + + Alternatively, you could use an in-line Python expression + in the following form: + + inherit ${@'classname' if condition else ''} + inherit ${@functionname(params)} + + In all cases, if the expression evaluates to an empty + string, the statement does not trigger a syntax error + because it becomes a no-op. + +
+ +
+ <filename>include</filename> Directive + + + BitBake understands the include + directive. + This directive causes BitBake to parse whatever file you specify, + and to insert that file at that location. + The directive is much like its equivalent in Make except + that if the path specified on the include line is a relative + path, BitBake locates the first file it can find + within BBPATH. + + + + The include directive is a more generic method of including + functionality as compared to the + inherit directive, + which is restricted to class (i.e. .bbclass) + files. + The include directive is applicable for any other kind of + shared or encapsulated functionality or configuration that + does not suit a .bbclass file. + + + + As an example, suppose you needed a recipe to include some + self-test definitions: + + include test_defs.inc + + + The include directive does not + produce an error when the file cannot be found. + Consequently, it is recommended that if the file you + are including is expected to exist, you should use + require + instead of include. + Doing so makes sure that an error is produced if the + file cannot be found. + + +
+ +
+ <filename>require</filename> Directive + + + BitBake understands the require + directive. + This directive behaves just like the + include directive with the exception that + BitBake raises a parsing error if the file to be included cannot + be found. + Thus, any file you require is inserted into the file that is + being parsed at the location of the directive. + + + + The require directive, like the include directive previously + described, is a more generic method of including + functionality as compared to the + inherit directive, + which is restricted to class (i.e. .bbclass) + files. + The require directive is applicable for any other kind of + shared or encapsulated functionality or configuration that + does not suit a .bbclass file. + + + + Similar to how BitBake handles + include, + if the path specified + on the require line is a relative path, BitBake locates + the first file it can find within BBPATH. + + + + As an example, suppose you have two versions of a recipe + (e.g. foo_1.2.2.bb and + foo_2.0.0.bb) where + each version contains some identical functionality that could be + shared. + You could create an include file named foo.inc + that contains the common definitions needed to build "foo". + You need to be sure foo.inc is located in the + same directory as your two recipe files as well. + Once these conditions are set up, you can share the functionality + using a require directive from within each + recipe: + + require foo.inc + + +
+ +
+ <filename>INHERIT</filename> Configuration Directive + + + When creating a configuration file (.conf), + you can use the + INHERIT + configuration directive to inherit a class. + BitBake only supports this directive when used within + a configuration file. + + + + As an example, suppose you needed to inherit a class + file called abc.bbclass from a + configuration file as follows: + + INHERIT += "abc" + + This configuration directive causes the named + class to be inherited at the point of the directive + during parsing. + As with the inherit directive, the + .bbclass file must be located in a + "classes" subdirectory in one of the directories specified + in BBPATH. + + Because .conf files are parsed + first during BitBake's execution, using + INHERIT to inherit a class effectively + inherits the class globally (i.e. for all recipes). + + If you want to use the directive to inherit + multiple classes, you can provide them on the same line in the + local.conf file. + Use spaces to separate the classes. + The following example shows how to inherit both the + autotools and pkgconfig + classes: + + INHERIT += "autotools pkgconfig" + + +
+
+ +
+ Functions + + + As with most languages, functions are the building blocks that + are used to build up operations into tasks. + BitBake supports these types of functions: + + Shell Functions: + Functions written in shell script and executed either + directly as functions, tasks, or both. + They can also be called by other shell functions. + + BitBake-Style Python Functions: + Functions written in Python and executed by BitBake or other + Python functions using bb.build.exec_func(). + + Python Functions: + Functions written in Python and executed by Python. + + Anonymous Python Functions: + Python functions executed automatically during + parsing. + + + Regardless of the type of function, you can only + define them in class (.bbclass) + and recipe (.bb or .inc) + files. + + +
+ Shell Functions + + + Functions written in shell script and executed either + directly as functions, tasks, or both. + They can also be called by other shell functions. + Here is an example shell function definition: + + some_function () { + echo "Hello World" + } + + When you create these types of functions in your recipe + or class files, you need to follow the shell programming + rules. + The scripts are executed by /bin/sh, + which may not be a bash shell but might be something + such as dash. + You should not use Bash-specific script (bashisms). + + + + Overrides and override-style operators like + _append and + _prepend can also be applied to + shell functions. + Most commonly, this application would be used in a + .bbappend file to modify functions in + the main recipe. + It can also be used to modify functions inherited from + classes. + + + + As an example, consider the following: + + do_foo() { + bbplain first + fn + } + + fn_prepend() { + bbplain second + } + + fn() { + bbplain third + } + + do_foo_append() { + bbplain fourth + } + + Running do_foo + prints the following: + + recipename do_foo: first + recipename do_foo: second + recipename do_foo: third + recipename do_foo: fourth + + + Overrides and override-style operators can + be applied to any shell function, not just + tasks. + + You can use the bitbake -e recipename + command to view the final assembled function + after all overrides have been applied. + +
+ +
+ BitBake-Style Python Functions + + + These functions are written in Python and executed by + BitBake or other Python functions using + bb.build.exec_func(). + + + + An example BitBake function is: + + python some_python_function () { + d.setVar("TEXT", "Hello World") + print d.getVar("TEXT") + } + + Because the Python "bb" and "os" modules are already + imported, you do not need to import these modules. + Also in these types of functions, the datastore ("d") + is a global variable and is always automatically + available. + + Variable expressions (e.g. ${X}) + are no longer expanded within Python functions. + This behavior is intentional in order to allow you + to freely set variable values to expandable expressions + without having them expanded prematurely. + If you do wish to expand a variable within a Python + function, use d.getVar("X"). + Or, for more complicated expressions, use + d.expand(). + + + + + Similar to shell functions, you can also apply overrides + and override-style operators to BitBake-style Python + functions. + + + + As an example, consider the following: + + python do_foo_prepend() { + bb.plain("first") + } + + python do_foo() { + bb.plain("second") + } + + python do_foo_append() { + bb.plain("third") + } + + Running do_foo prints + the following: + + recipename do_foo: first + recipename do_foo: second + recipename do_foo: third + + You can use the bitbake -e recipename + command to view the final assembled function + after all overrides have been applied. + +
+ +
+ Python Functions + + + These functions are written in Python and are executed by + other Python code. + Examples of Python functions are utility functions + that you intend to call from in-line Python or + from within other Python functions. + Here is an example: + + def get_depends(d): + if d.getVar('SOMECONDITION'): + return "dependencywithcond" + else: + return "dependency" + SOMECONDITION = "1" + DEPENDS = "${@get_depends(d)}" + + This would result in DEPENDS + containing dependencywithcond. + + + + Here are some things to know about Python functions: + + Python functions can take parameters. + + The BitBake datastore is not + automatically available. + Consequently, you must pass it in as a + parameter to the function. + + The "bb" and "os" Python modules are + automatically available. + You do not need to import them. + + + +
+ +
+ Bitbake-Style Python Functions Versus Python Functions + + + Following are some important differences between + BitBake-style Python functions and regular Python + functions defined with "def": + + + Only BitBake-style Python functions can be + tasks. + + + Overrides and override-style operators can only + be applied to BitBake-style Python functions. + + + Only regular Python functions can take arguments + and return values. + + + Variable flags + such as [dirs], + [cleandirs], and + [lockfiles] can be used + on BitBake-style Python functions, but not on + regular Python functions. + + + BitBake-style Python functions generate a separate + ${T}/run.function-name.pid + script that is executed to run the function, and also + generate a log file in + ${T}/log.function-name.pid + if they are executed as tasks. + + + Regular Python functions execute "inline" and do not + generate any files in ${T}. + + + Regular Python functions are called with the usual + Python syntax. + BitBake-style Python functions are usually tasks and + are called directly by BitBake, but can also be called + manually from Python code by using the + bb.build.exec_func() function. + Here is an example: + + bb.build.exec_func("my_bitbake_style_function", d) + + + bb.build.exec_func() can also + be used to run shell functions from Python code. + If you want to run a shell function before a Python + function within the same task, then you can use a + parent helper Python function that starts by running + the shell function with + bb.build.exec_func() and then + runs the Python code. + + + To detect errors from functions executed with + bb.build.exec_func(), you + can catch the bb.build.FuncFailed + exception. + + Functions in metadata (recipes and classes) should + not themselves raise + bb.build.FuncFailed. + Rather, bb.build.FuncFailed + should be viewed as a general indicator that the + called function failed by raising an exception. + For example, an exception raised by + bb.fatal() will be caught inside + bb.build.exec_func(), and a + bb.build.FuncFailed will be raised + in response. + + + + + + + Due to their simplicity, you should prefer regular Python functions + over BitBake-style Python functions unless you need a feature specific + to BitBake-style Python functions. + Regular Python functions in metadata are a more recent invention than + BitBake-style Python functions, and older code tends to use + bb.build.exec_func() more often. + +

+ Anonymous Python Functions + + + Sometimes it is useful to set variables or perform + other operations programmatically during parsing. + To do this, you can define special Python functions, + called anonymous Python functions, that run at the + end of parsing. + For example, the following conditionally sets a variable + based on the value of another variable: + + python () { + if d.getVar('SOMEVAR') == 'value': + d.setVar('ANOTHERVAR', 'value2') + } + + An equivalent way to mark a function as an anonymous + function is to give it the name "__anonymous", rather + than no name. + + + + Anonymous Python functions always run at the end + of parsing, regardless of where they are defined. + If a recipe contains many anonymous functions, they + run in the same order as they are defined within the + recipe. + As an example, consider the following snippet: + + python () { + d.setVar('FOO', 'foo 2') + } + + FOO = "foo 1" + + python () { + d.appendVar('BAR', ' bar 2') + } + + BAR = "bar 1" + + The previous example is conceptually equivalent to the + following snippet: + + FOO = "foo 1" + BAR = "bar 1" + FOO = "foo 2" + BAR += "bar 2" + + FOO ends up with the value "foo 2", + and BAR with the value "bar 1 bar 2". + Just as in the second snippet, the values set for the + variables within the anonymous functions become available + to tasks, which always run after parsing. + + + + Overrides and override-style operators such as + "_append" are applied before + anonymous functions run. + In the following example, FOO ends + up with the value "foo from anonymous": + + FOO = "foo" + FOO_append = " from outside" + + python () { + d.setVar("FOO", "foo from anonymous") + } + + For methods you can use with anonymous Python functions, + see the + "Functions You Can Call From Within Python" + section. + For a different method to run Python code during parsing, + see the + "Inline Python Variable Expansion" + section. + +
+ +
+ Flexible Inheritance for Class Functions + + + Through coding techniques and the use of + EXPORT_FUNCTIONS, BitBake supports + exporting a function from a class such that the + class function appears as the default implementation + of the function, but can still be called if a recipe + inheriting the class needs to define its own version of + the function. + + + + To understand the benefits of this feature, consider + the basic scenario where a class defines a task function + and your recipe inherits the class. + In this basic scenario, your recipe inherits the task + function as defined in the class. + If desired, your recipe can add to the start and end of the + function by using the "_prepend" or "_append" operations + respectively, or it can redefine the function completely. + However, if it redefines the function, there is + no means for it to call the class version of the function. + EXPORT_FUNCTIONS provides a mechanism + that enables the recipe's version of the function to call + the original version of the function. + + + + To make use of this technique, you need the following + things in place: + + + The class needs to define the function as follows: + + classname_functionname + + For example, if you have a class file + bar.bbclass and a function named + do_foo, the class must define the function + as follows: + + bar_do_foo + + + + The class needs to contain the EXPORT_FUNCTIONS + statement as follows: + + EXPORT_FUNCTIONS functionname + + For example, continuing with the same example, the + statement in the bar.bbclass would be + as follows: + + EXPORT_FUNCTIONS do_foo + + + + You need to call the function appropriately from within your + recipe. + Continuing with the same example, if your recipe + needs to call the class version of the function, + it should call bar_do_foo. + Assuming do_foo was a shell function + and EXPORT_FUNCTIONS was used as above, + the recipe's function could conditionally call the + class version of the function as follows: + + do_foo() { + if [ somecondition ] ; then + bar_do_foo + else + # Do something else + fi + } + + To call your modified version of the function as defined + in your recipe, call it as do_foo. + + + With these conditions met, your single recipe + can freely choose between the original function + as defined in the class file and the modified function in your recipe. + If you do not set up these conditions, you are limited to using one function + or the other. + +
+
+ +
+ Tasks + + + Tasks are BitBake execution units that make up the + steps that BitBake can run for a given recipe. + Tasks are only supported in recipes and classes + (i.e. in .bb files and files + included or inherited from .bb + files). + By convention, tasks have names that start with "do_". + + +
+ Promoting a Function to a Task + + + Tasks are either + shell functions or + BitBake-style Python functions + that have been promoted to tasks by using the + addtask command. + The addtask command can also + optionally describe dependencies between the + task and other tasks. + Here is an example that shows how to define a task + and declare some dependencies: + + python do_printdate () { + import time + print time.strftime('%Y%m%d', time.gmtime()) + } + addtask printdate after do_fetch before do_build + + The first argument to addtask + is the name of the function to promote to + a task. + If the name does not start with "do_", "do_" is + implicitly added, which enforces the convention that + all task names start with "do_". + + + + In the previous example, the + do_printdate task becomes a + dependency of the do_build + task, which is the default task (i.e. the task run by + the bitbake command unless + another task is specified explicitly). + Additionally, the do_printdate + task becomes dependent upon the + do_fetch task. + Running the do_build task + results in the do_printdate + task running first. + + If you try out the previous example, you might see that + the do_printdate task is only run + the first time you build the recipe with + the bitbake command. + This is because BitBake considers the task "up-to-date" + after that initial run. + If you want to force the task to always be rerun for + experimentation purposes, you can make BitBake always + consider the task "out-of-date" by using the + [nostamp] + variable flag, as follows: + + do_printdate[nostamp] = "1" + + You can also explicitly run the task and provide the + -f option as follows: + + $ bitbake recipe -c printdate -f + + When manually selecting a task to run with the + bitbake recipe -c task + command, you can omit the "do_" prefix as part of the + task name. + + + + + You might wonder about the practical effects of using + addtask without specifying any + dependencies as is done in the following example: + + addtask printdate + + In this example, assuming dependencies have not been + added through some other means, the only way to run + the task is by explicitly selecting it with + bitbake recipe -c printdate. + You can use the + do_listtasks task to list all tasks + defined in a recipe as shown in the following example: + + $ bitbake recipe -c listtasks + + For more information on task dependencies, see the + "Dependencies" + section. + + + + See the + "Variable Flags" + section for information on variable flags you can use with + tasks. + +
+ +
+ Deleting a Task + + + As well as being able to add tasks, you can delete them. + Simply use the deltask command to + delete a task. + For example, to delete the example task used in the previous + sections, you would use: + + deltask printdate + + If you delete a task using the deltask + command and the task has dependencies, the dependencies are + not reconnected. + For example, suppose you have three tasks named + do_a, do_b, and + do_c. + Furthermore, do_c is dependent on + do_b, which in turn is dependent on + do_a. + Given this scenario, if you use deltask + to delete do_b, the implicit dependency + relationship between do_c and + do_a through do_b + no longer exists, and do_c dependencies + are not updated to include do_a. + Thus, do_c is free to run before + do_a. + + + + If you want dependencies such as these to remain intact, use + the [noexec] varflag to disable the task + instead of using the deltask command to + delete it: + + do_b[noexec] = "1" + + +
+ +
+ Passing Information Into the Build Task Environment + + + When running a task, BitBake tightly controls the shell execution + environment of the build tasks to make + sure unwanted contamination from the build machine cannot + influence the build. + + By default, BitBake cleans the environment to include only those + things exported or listed in its whitelist to ensure that the build + environment is reproducible and consistent. + You can prevent this "cleaning" by setting the + BB_PRESERVE_ENV + variable. + + Consequently, if you do want something to get passed into the + build task environment, you must take these two steps: + + + Tell BitBake to load what you want from the environment + into the datastore. + You can do so through the + BB_ENV_WHITELIST + and + BB_ENV_EXTRAWHITE + variables. + For example, assume you want to prevent the build system from + accessing your $HOME/.ccache + directory. + The following command "whitelists" the environment variable + CCACHE_DIR causing BitBack to allow that + variable into the datastore: + + export BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE CCACHE_DIR" + + + Tell BitBake to export what you have loaded into the + datastore to the task environment of every running task. + Loading something from the environment into the datastore + (previous step) only makes it available in the datastore. + To export it to the task environment of every running task, + use a command similar to the following in your local configuration + file local.conf or your + distribution configuration file: + + export CCACHE_DIR + + + A side effect of the previous steps is that BitBake + records the variable as a dependency of the build process + in things like the setscene checksums. + If doing so results in unnecessary rebuilds of tasks, you can + whitelist the variable so that the setscene code + ignores the dependency when it creates checksums. + + + + + + Sometimes, it is useful to be able to obtain information + from the original execution environment. + Bitbake saves a copy of the original environment into + a special variable named + BB_ORIGENV. + + + + The BB_ORIGENV variable returns a datastore + object that can be queried using the standard datastore operators + such as getVar(, False). + The datastore object is useful, for example, to find the original + DISPLAY variable. + Here is an example: + + origenv = d.getVar("BB_ORIGENV", False) + bar = origenv.getVar("BAR", False) + + The previous example returns BAR from the original + execution environment. + +
+
+ +
+ Variable Flags + + + Variable flags (varflags) help control a task's functionality + and dependencies. + BitBake reads and writes varflags to the datastore using the following + command forms: + + variable = d.getVarFlags("variable") + self.d.setVarFlags("FOO", {"func": True}) + + + + + When working with varflags, the same syntax, with the exception of + overrides, applies. + In other words, you can set, append, and prepend varflags just like + variables. + See the + "Variable Flag Syntax" + section for details. + + + + BitBake has a defined set of varflags available for recipes and + classes. + Tasks support a number of these flags which control various + functionality of the task: + + [cleandirs]: + Empty directories that should be created before the + task runs. + Directories that already exist are removed and recreated + to empty them. + + [depends]: + Controls inter-task dependencies. + See the + DEPENDS + variable and the + "Inter-Task Dependencies" + section for more information. + + [deptask]: + Controls task build-time dependencies. + See the + DEPENDS + variable and the + "Build Dependencies" + section for more information. + + [dirs]: + Directories that should be created before the task runs. + Directories that already exist are left as is. + The last directory listed is used as the + current working directory for the task. + + [lockfiles]: + Specifies one or more lockfiles to lock while the task + executes. + Only one task may hold a lockfile, and any task that + attempts to lock an already locked file will block until + the lock is released. + You can use this variable flag to accomplish mutual + exclusion. + + [noexec]: + When set to "1", marks the task as being empty, with + no execution required. + You can use the [noexec] flag to set up + tasks as dependency placeholders, or to disable tasks defined + elsewhere that are not needed in a particular recipe. + + [nostamp]: + When set to "1", tells BitBake to not generate a stamp + file for a task, which implies the task should always + be executed. + Caution + Any task that depends (possibly indirectly) on a + [nostamp] task will always be + executed as well. + This can cause unnecessary rebuilding if you are + not careful. + + + [postfuncs]: + List of functions to call after the completion of the task. + + [prefuncs]: + List of functions to call before the task executes. + + [rdepends]: + Controls inter-task runtime dependencies. + See the + RDEPENDS + variable, the + RRECOMMENDS + variable, and the + "Inter-Task Dependencies" + section for more information. + + [rdeptask]: + Controls task runtime dependencies. + See the + RDEPENDS + variable, the + RRECOMMENDS + variable, and the + "Runtime Dependencies" + section for more information. + + [recideptask]: + When set in conjunction with + recrdeptask, specifies a task that + should be inspected for additional dependencies. + + [recrdeptask]: + Controls task recursive runtime dependencies. + See the + RDEPENDS + variable, the + RRECOMMENDS + variable, and the + "Recursive Dependencies" + section for more information. + + [stamp-extra-info]: + Extra stamp information to append to the task's stamp. + As an example, OpenEmbedded uses this flag to allow + machine-specific tasks. + + [umask]: + The umask to run the task under. + + + + + + Several varflags are useful for controlling how signatures are + calculated for variables. + For more information on this process, see the + "Checksums (Signatures)" + section. + + [vardeps]: + Specifies a space-separated list of additional + variables to add to a variable's dependencies + for the purposes of calculating its signature. + Adding variables to this list is useful, for example, when + a function refers to a variable in a manner that + does not allow BitBake to automatically determine + that the variable is referred to. + + [vardepsexclude]: + Specifies a space-separated list of variables + that should be excluded from a variable's dependencies + for the purposes of calculating its signature. + + [vardepvalue]: + If set, instructs BitBake to ignore the actual + value of the variable and instead use the specified + value when calculating the variable's signature. + + [vardepvalueexclude]: + Specifies a pipe-separated list of strings to exclude + from the variable's value when calculating the + variable's signature. + + + +
+ +
+ Events + + + BitBake allows installation of event handlers within recipe + and class files. + Events are triggered at certain points during operation, such + as the beginning of operation against a given recipe + (i.e. *.bb), the start of a given task, + a task failure, a task success, and so forth. + The intent is to make it easy to do things like email + notification on build failures. + + + + Following is an example event handler that prints the name + of the event and the content of the + FILE variable: + + addhandler myclass_eventhandler + python myclass_eventhandler() { + from bb.event import getName + print("The name of the Event is %s" % getName(e)) + print("The file we run for is %s" % d.getVar('FILE')) + } + myclass_eventhandler[eventmask] = "bb.event.BuildStarted bb.event.BuildCompleted" + + In the previous example, an eventmask has been set so that + the handler only sees the "BuildStarted" and "BuildCompleted" + events. + This event handler gets called every time an event matching + the eventmask is triggered. + A global variable "e" is defined, which represents the current + event. + With the getName(e) method, you can get + the name of the triggered event. + The global datastore is available as "d". + In legacy code, you might see "e.data" used to get the datastore. + However, realize that "e.data" is deprecated and you should use + "d" going forward. + + + + The context of the datastore is appropriate to the event + in question. + For example, "BuildStarted" and "BuildCompleted" events run + before any tasks are executed so would be in the global + configuration datastore namespace. + No recipe-specific metadata exists in that namespace. + The "BuildStarted" and "BuildCompleted" events also run in + the main cooker/server process rather than any worker context. + Thus, any changes made to the datastore would be seen by other + cooker/server events within the current build but not seen + outside of that build or in any worker context. + Task events run in the actual tasks in question consequently + have recipe-specific and task-specific contents. + These events run in the worker context and are discarded at + the end of task execution. + + + + During a standard build, the following common events might + occur. + The following events are the most common kinds of events that + most metadata might have an interest in viewing: + + + bb.event.ConfigParsed(): + Fired when the base configuration; which consists of + bitbake.conf, + base.bbclass and any global + INHERIT statements; has been parsed. + You can see multiple such events when each of the + workers parse the base configuration or if the server + changes configuration and reparses. + Any given datastore only has one such event executed + against it, however. + If + BB_INVALIDCONF + is set in the datastore by the event handler, the + configuration is reparsed and a new event triggered, + allowing the metadata to update configuration. + + + bb.event.HeartbeatEvent(): + Fires at regular time intervals of one second. + You can configure the interval time using the + BB_HEARTBEAT_EVENT variable. + The event's "time" attribute is the + time.time() value when the + event is triggered. + This event is useful for activities such as + system state monitoring. + + + bb.event.ParseStarted(): + Fired when BitBake is about to start parsing recipes. + This event's "total" attribute represents the number of + recipes BitBake plans to parse. + + + bb.event.ParseProgress(): + Fired as parsing progresses. + This event's "current" attribute is the number of + recipes parsed as well as the "total" attribute. + + + bb.event.ParseCompleted(): + Fired when parsing is complete. + This event's "cached", "parsed", "skipped", "virtuals", + "masked", and "errors" attributes provide statistics + for the parsing results. + + + bb.event.BuildStarted(): + Fired when a new build starts. + BitBake fires multiple "BuildStarted" events (one per configuration) + when multiple configuration (multiconfig) is enabled. + + + bb.build.TaskStarted(): + Fired when a task starts. + This event's "taskfile" attribute points to the recipe + from which the task originates. + The "taskname" attribute, which is the task's name, + includes the do_ prefix, and the + "logfile" attribute point to where the task's output is + stored. + Finally, the "time" attribute is the task's execution start + time. + + + bb.build.TaskInvalid(): + Fired if BitBake tries to execute a task that does not exist. + + + bb.build.TaskFailedSilent(): + Fired for setscene tasks that fail and should not be + presented to the user verbosely. + + + bb.build.TaskFailed(): + Fired for normal tasks that fail. + + + bb.build.TaskSucceeded(): + Fired when a task successfully completes. + + + bb.event.BuildCompleted(): + Fired when a build finishes. + + + bb.cooker.CookerExit(): + Fired when the BitBake server/cooker shuts down. + This event is usually only seen by the UIs as a + sign they should also shutdown. + + + + + + This next list of example events occur based on specific + requests to the server. + These events are often used to communicate larger pieces of + information from the BitBake server to other parts of + BitBake such as user interfaces: + + + bb.event.TreeDataPreparationStarted() + + + bb.event.TreeDataPreparationProgress() + + + bb.event.TreeDataPreparationCompleted() + + + bb.event.DepTreeGenerated() + + + bb.event.CoreBaseFilesFound() + + + bb.event.ConfigFilePathFound() + + + bb.event.FilesMatchingFound() + + + bb.event.ConfigFilesFound() + + + bb.event.TargetsTreeGenerated() + + + +
+ +
+ Variants - Class Extension Mechanism + + + BitBake supports two features that facilitate creating + from a single recipe file multiple incarnations of that + recipe file where all incarnations are buildable. + These features are enabled through the + BBCLASSEXTEND + and + BBVERSIONS + variables. + + The mechanism for this class extension is extremely + specific to the implementation. + Usually, the recipe's + PROVIDES, + PN, and + DEPENDS + variables would need to be modified by the extension class. + For specific examples, see the OE-Core + native, nativesdk, + and multilib classes. + + + BBCLASSEXTEND: + This variable is a space separated list of classes used to "extend" the + recipe for each variant. + Here is an example that results in a second incarnation of the current + recipe being available. + This second incarnation will have the "native" class inherited. + + BBCLASSEXTEND = "native" + + BBVERSIONS: + This variable allows a single recipe to build multiple versions of a + project from a single recipe file. + You can also specify conditional metadata + (using the + OVERRIDES + mechanism) for a single version, or an optionally named range of versions. + Here is an example: + + BBVERSIONS = "1.0 2.0 git" + SRC_URI_git = "git://someurl/somepath.git" + + BBVERSIONS = "1.0.[0-6]:1.0.0+ \ 1.0.[7-9]:1.0.7+" + SRC_URI_append_1.0.7+ = "file://some_patch_which_the_new_versions_need.patch;patch=1" + + The name of the range defaults to the original version of the + recipe. + For example, in OpenEmbedded, the recipe file + foo_1.0.0+.bb creates a default name range + of 1.0.0+. + This is useful because the range name is not only placed + into overrides, but it is also made available for the metadata to use + in the variable that defines the base recipe versions for use in + file:// search paths + (FILESPATH). + + + +
+ +
+ Dependencies + + + To allow for efficient parallel processing, BitBake handles + dependencies at the task level. + Dependencies can exist both between tasks within a single recipe + and between tasks in different recipes. + Following are examples of each: + + For tasks within a single recipe, a + recipe's do_configure + task might need to complete before its + do_compile task can run. + + For tasks in different recipes, one + recipe's do_configure + task might require another recipe's + do_populate_sysroot + task to finish first such that the libraries and headers + provided by the other recipe are available. + + + + + + This section describes several ways to declare dependencies. + Remember, even though dependencies are declared in different ways, they + are all simply dependencies between tasks. + + +
+ Dependencies Internal to the <filename>.bb</filename> File + + + BitBake uses the addtask directive + to manage dependencies that are internal to a given recipe + file. + You can use the addtask directive to + indicate when a task is dependent on other tasks or when + other tasks depend on that recipe. + Here is an example: + + addtask printdate after do_fetch before do_build + + In this example, the do_printdate + task depends on the completion of the + do_fetch task, and the + do_build task depends on the + completion of the do_printdate + task. + + For a task to run, it must be a direct or indirect + dependency of some other task that is scheduled to + run. + + For illustration, here are some examples: + + + The directive + addtask mytask before do_configure + causes do_mytask to run before + do_configure runs. + Be aware that do_mytask still only + runs if its input checksum + has changed since the last time it was run. + Changes to the input checksum of + do_mytask also indirectly cause + do_configure to run. + + + The directive + addtask mytask after do_configure + by itself never causes do_mytask + to run. + do_mytask can still be run manually + as follows: + + $ bitbake recipe -c mytask + + Declaring do_mytask as a dependency + of some other task that is scheduled to run also causes + it to run. + Regardless, the task runs after + do_configure. + + + + +
+ +
+ Build Dependencies + + + BitBake uses the + DEPENDS + variable to manage build time dependencies. + The [deptask] varflag for tasks + signifies the task of each + item listed in DEPENDS that must + complete before that task can be executed. + Here is an example: + + do_configure[deptask] = "do_populate_sysroot" + + In this example, the do_populate_sysroot + task of each item in DEPENDS must complete before + do_configure can execute. + +
+ +
+ Runtime Dependencies + + + BitBake uses the + PACKAGES, + RDEPENDS, and + RRECOMMENDS + variables to manage runtime dependencies. + + + + The PACKAGES variable lists runtime + packages. + Each of those packages can have RDEPENDS and + RRECOMMENDS runtime dependencies. + The [rdeptask] flag for tasks is used to + signify the task of each + item runtime dependency which must have completed before that + task can be executed. + + do_package_qa[rdeptask] = "do_packagedata" + + In the previous example, the do_packagedata + task of each item in RDEPENDS must have + completed before do_package_qa can execute. + +
+ +
+ Recursive Dependencies + + + BitBake uses the [recrdeptask] flag to manage + recursive task dependencies. + BitBake looks through the build-time and runtime + dependencies of the current recipe, looks through + the task's inter-task + dependencies, and then adds dependencies for the + listed task. + Once BitBake has accomplished this, it recursively works through + the dependencies of those tasks. + Iterative passes continue until all dependencies are discovered + and added. + + + + The [recrdeptask] flag is most commonly + used in high-level + recipes that need to wait for some task to finish "globally". + For example, image.bbclass has the following: + + do_rootfs[recrdeptask] += "do_packagedata" + + This statement says that the do_packagedata + task of the current recipe and all recipes reachable + (by way of dependencies) from the + image recipe must run before the do_rootfs + task can run. + + + + You might want to not only have BitBake look for + dependencies of those tasks, but also have BitBake look + for build-time and runtime dependencies of the dependent + tasks as well. + If that is the case, you need to reference the task name + itself in the task list: + + do_a[recrdeptask] = "do_a do_b" + + +
+ +
+ Inter-Task Dependencies + + + BitBake uses the [depends] + flag in a more generic form + to manage inter-task dependencies. + This more generic form allows for inter-dependency + checks for specific tasks rather than checks for + the data in DEPENDS. + Here is an example: + + do_patch[depends] = "quilt-native:do_populate_sysroot" + + In this example, the do_populate_sysroot + task of the target quilt-native + must have completed before the + do_patch task can execute. + + + + The [rdepends] flag works in a similar + way but takes targets + in the runtime namespace instead of the build-time dependency + namespace. + +
+
+ +
+ Functions You Can Call From Within Python + + + BitBake provides many functions you can call from + within Python functions. + This section lists the most commonly used functions, + and mentions where to find others. + + +
+ Functions for Accessing Datastore Variables + + + It is often necessary to access variables in the + BitBake datastore using Python functions. + The Bitbake datastore has an API that allows you this + access. + Here is a list of available operations: + + + + + + + + + + Operation + Description + + + + + d.getVar("X", expand) + Returns the value of variable "X". + Using "expand=True" expands the value. + Returns "None" if the variable "X" does not exist. + + + d.setVar("X", "value") + Sets the variable "X" to "value". + + + d.appendVar("X", "value") + Adds "value" to the end of the variable "X". + Acts like d.setVar("X", "value") + if the variable "X" does not exist. + + + d.prependVar("X", "value") + Adds "value" to the start of the variable "X". + Acts like d.setVar("X", "value") + if the variable "X" does not exist. + + + d.delVar("X") + Deletes the variable "X" from the datastore. + Does nothing if the variable "X" does not exist. + + + d.renameVar("X", "Y") + Renames the variable "X" to "Y". + Does nothing if the variable "X" does not exist. + + + d.getVarFlag("X", flag, expand) + Returns the value of variable "X". + Using "expand=True" expands the value. + Returns "None" if either the variable "X" or the named flag + does not exist. + + + d.setVarFlag("X", flag, "value") + Sets the named flag for variable "X" to "value". + + + d.appendVarFlag("X", flag, "value") + Appends "value" to the named flag on the + variable "X". + Acts like d.setVarFlag("X", flag, "value") + if the named flag does not exist. + + + d.prependVarFlag("X", flag, "value") + Prepends "value" to the named flag on + the variable "X". + Acts like d.setVarFlag("X", flag, "value") + if the named flag does not exist. + + + d.delVarFlag("X", flag) + Deletes the named flag on the variable + "X" from the datastore. + + + d.setVarFlags("X", flagsdict) + Sets the flags specified in + the flagsdict() parameter. + setVarFlags does not clear previous flags. + Think of this operation as addVarFlags. + + + d.getVarFlags("X") + Returns a flagsdict + of the flags for the variable "X". + Returns "None" if the variable "X" does not exist. + + + d.delVarFlags("X") + Deletes all the flags for the variable "X". + Does nothing if the variable "X" does not exist. + + + d.expand(expression) + Expands variable references in the specified + string expression. + References to variables that do not exist are left as is. + For example, d.expand("foo ${X}") + expands to the literal string "foo ${X}" if the + variable "X" does not exist. + + + + + +

+ Task Checksums and Setscene + + + BitBake uses checksums (or signatures) along with the setscene + to determine if a task needs to be run. + This section describes the process. + To help understand how BitBake does this, the section assumes an + OpenEmbedded metadata-based example. + + + + These checksums are stored in + STAMP. + You can examine the checksums using the following BitBake command: + + $ bitbake-dumpsigs + + This command returns the signature data in a readable format + that allows you to examine the inputs used when the + OpenEmbedded build system generates signatures. + For example, using bitbake-dumpsigs + allows you to examine the do_compile + task's “sigdata†for a C application (e.g. + bash). + Running the command also reveals that the “CC†variable is part of + the inputs that are hashed. + Any changes to this variable would invalidate the stamp and + cause the do_compile task to run. + + + + The following list describes related variables: + + + BB_HASHCHECK_FUNCTION: + Specifies the name of the function to call during + the "setscene" part of the task's execution in order + to validate the list of task hashes. + + + BB_SETSCENE_DEPVALID: + Specifies a function BitBake calls that determines + whether BitBake requires a setscene dependency to + be met. + + + BB_SETSCENE_VERIFY_FUNCTION2: + Specifies a function to call that verifies the list of + planned task execution before the main task execution + happens. + + + BB_STAMP_POLICY: + Defines the mode for comparing timestamps of stamp files. + + + BB_STAMP_WHITELIST: + Lists stamp files that are looked at when the stamp policy + is "whitelist". + + + BB_TASKHASH: + Within an executing task, this variable holds the hash + of the task as returned by the currently enabled + signature generator. + + + STAMP: + The base path to create stamp files. + + + STAMPCLEAN: + Again, the base path to create stamp files but can use wildcards + for matching a range of files for clean operations. + + + +

You can specify one or + more directories to monitor by separating the + groupings with a space. If two directories are + on the same device, only the first directory + is monitored. + + <threshold> is: + Either the minimum available disk space, + the minimum number of free inodes, or + both. You must specify at least one. To + omit one or the other, simply omit the value. + Specify the threshold using G, M, K for Gbytes, + Mbytes, and Kbytes, respectively. If you do + not specify G, M, or K, Kbytes is assumed by + default. Do not use GB, MB, or KB. + + + + + Here are some examples: + + BB_DISKMON_DIRS = "ABORT,${TMPDIR},1G,100K WARN,${SSTATE_DIR},1G,100K" + BB_DISKMON_DIRS = "STOPTASKS,${TMPDIR},1G" + BB_DISKMON_DIRS = "ABORT,${TMPDIR},,100K" + + The first example works only if you also set + the BB_DISKMON_WARNINTERVAL variable. + This example causes the build system to immediately + abort when either the disk space in ${TMPDIR} drops + below 1 Gbyte or the available free inodes drops below + 100 Kbytes. + Because two directories are provided with the variable, the + build system also issues a + warning when the disk space in the + ${SSTATE_DIR} directory drops + below 1 Gbyte or the number of free inodes drops + below 100 Kbytes. + Subsequent warnings are issued during intervals as + defined by the BB_DISKMON_WARNINTERVAL + variable. + + + + The second example stops the build after all currently + executing tasks complete when the minimum disk space + in the ${TMPDIR} + directory drops below 1 Gbyte. + No disk monitoring occurs for the free inodes in this case. + + + + The final example immediately aborts the build when the + number of free inodes in the ${TMPDIR} directory + drops below 100 Kbytes. + No disk space monitoring for the directory itself occurs + in this case. + + + + + BB_DISKMON_WARNINTERVAL + + + Defines the disk space and free inode warning intervals. + + + + If you are going to use the + BB_DISKMON_WARNINTERVAL variable, you must + also use the + BB_DISKMON_DIRS variable + and define its action as "WARN". + During the build, subsequent warnings are issued each time + disk space or number of free inodes further reduces by + the respective interval. + + + + If you do not provide a BB_DISKMON_WARNINTERVAL + variable and you do use BB_DISKMON_DIRS with + the "WARN" action, the disk monitoring interval defaults to + the following: + + BB_DISKMON_WARNINTERVAL = "50M,5K" + + + + + When specifying the variable in your configuration file, + use the following form: + + BB_DISKMON_WARNINTERVAL = "<disk_space_interval>,<disk_inode_interval>" + + where: + + <disk_space_interval> is: + An interval of memory expressed in either + G, M, or K for Gbytes, Mbytes, or Kbytes, + respectively. You cannot use GB, MB, or KB. + + <disk_inode_interval> is: + An interval of free inodes expressed in either + G, M, or K for Gbytes, Mbytes, or Kbytes, + respectively. You cannot use GB, MB, or KB. + + + + + Here is an example: + + BB_DISKMON_DIRS = "WARN,${SSTATE_DIR},1G,100K" + BB_DISKMON_WARNINTERVAL = "50M,5K" + + These variables cause BitBake to + issue subsequent warnings each time the available + disk space further reduces by 50 Mbytes or the number + of free inodes further reduces by 5 Kbytes in the + ${SSTATE_DIR} directory. + Subsequent warnings based on the interval occur each time + a respective interval is reached beyond the initial warning + (i.e. 1 Gbytes and 100 Kbytes). + + + + + BB_ENV_WHITELIST + + + Specifies the internal whitelist of variables to allow + through from the external environment into BitBake's + datastore. + If the value of this variable is not specified + (which is the default), the following list is used: + BBPATH, + BB_PRESERVE_ENV, + BB_ENV_WHITELIST, + and + BB_ENV_EXTRAWHITE. + + You must set this variable in the external environment + in order for it to work. + + + + + + BB_ENV_EXTRAWHITE + + + Specifies an additional set of variables to allow through + (whitelist) from the external environment into BitBake's + datastore. + This list of variables are on top of the internal list + set in + BB_ENV_WHITELIST. + + You must set this variable in the external + environment in order for it to work. + + + + + + BB_FETCH_PREMIRRORONLY + + + When set to "1", causes BitBake's fetcher module to only + search + PREMIRRORS + for files. + BitBake will not search the main + SRC_URI + or + MIRRORS. + + + + + BB_FILENAME + + + Contains the filename of the recipe that owns the currently + running task. + For example, if the do_fetch task that + resides in the my-recipe.bb is + executing, the BB_FILENAME variable + contains "/foo/path/my-recipe.bb". + + + + + BB_GENERATE_MIRROR_TARBALLS + + + Causes tarballs of the Git repositories, including the + Git metadata, to be placed in the + DL_DIR + directory. + Anyone wishing to create a source mirror would want to + enable this variable. + + + + For performance reasons, creating and placing tarballs of + the Git repositories is not the default action by BitBake. + + BB_GENERATE_MIRROR_TARBALLS = "1" + + + + + + BB_HASHCONFIG_WHITELIST + + + Lists variables that are excluded from base configuration + checksum, which is used to determine if the cache can + be reused. + + + + One of the ways BitBake determines whether to re-parse the + main metadata is through checksums of the variables in the + datastore of the base configuration data. + There are variables that you typically want to exclude when + checking whether or not to re-parse and thus rebuild the + cache. + As an example, you would usually exclude + TIME and DATE + because these variables are always changing. + If you did not exclude them, BitBake would never reuse the + cache. + + + + + BB_HASHBASE_WHITELIST + + + Lists variables that are excluded from checksum and + dependency data. + Variables that are excluded can therefore change without + affecting the checksum mechanism. + A common example would be the variable for the path of + the build. + BitBake's output should not (and usually does not) depend + on the directory in which it was built. + + + + + BB_HASHCHECK_FUNCTION + + + Specifies the name of the function to call during the + "setscene" part of the task's execution in order to + validate the list of task hashes. + The function returns the list of setscene tasks that should + be executed. + + + + At this point in the execution of the code, the objective + is to quickly verify if a given setscene function is likely + to work or not. + It's easier to check the list of setscene functions in + one pass than to call many individual tasks. + The returned list need not be completely accurate. + A given setscene task can still later fail. + However, the more accurate the data returned, the more + efficient the build will be. + + + + + BB_INVALIDCONF + + + Used in combination with the + ConfigParsed event to trigger + re-parsing the base metadata (i.e. all the + recipes). + The ConfigParsed event can set the + variable to trigger the re-parse. + You must be careful to avoid recursive loops with this + functionality. + + + + + BB_LOGFMT + + + Specifies the name of the log files saved into + ${T}. + By default, the BB_LOGFMT variable + is undefined and the log file names get created using the + following form: + + log.{task}.{pid} + + If you want to force log files to take a specific name, + you can set this variable in a configuration file. + + + + + BB_NICE_LEVEL + + + Allows BitBake to run at a specific priority + (i.e. nice level). + System permissions usually mean that BitBake can reduce its + priority but not raise it again. + See + BB_TASK_NICE_LEVEL + for additional information. + + + + + BB_NO_NETWORK + + + Disables network access in the BitBake fetcher modules. + With this access disabled, any command that attempts to + access the network becomes an error. + + + + Disabling network access is useful for testing source + mirrors, running builds when not connected to the Internet, + and when operating in certain kinds of firewall + environments. + + + + + BB_NUMBER_THREADS + + + The maximum number of tasks BitBake should run in parallel + at any one time. + If your host development system supports multiple cores, + a good rule of thumb is to set this variable to twice the + number of cores. + + + + + BB_NUMBER_PARSE_THREADS + + + Sets the number of threads BitBake uses when parsing. + By default, the number of threads is equal to the number + of cores on the system. + + + + + BB_ORIGENV + + + Contains a copy of the original external environment in + which BitBake was run. + The copy is taken before any whitelisted variable values + are filtered into BitBake's datastore. + + The contents of this variable is a datastore object + that can be queried using the normal datastore + operations. + + + + + + BB_PRESERVE_ENV + + + Disables whitelisting and instead allows all variables + through from the external environment into BitBake's + datastore. + + You must set this variable in the external + environment in order for it to work. + + + + + + BB_RUNFMT + + + Specifies the name of the executable script files + (i.e. run files) saved into + ${T}. + By default, the BB_RUNFMT variable + is undefined and the run file names get created using the + following form: + + run.{task}.{pid} + + If you want to force run files to take a specific name, + you can set this variable in a configuration file. + + + + + BB_RUNTASK + + + Contains the name of the currently executing task. + The value does not include the "do_" prefix. + For example, if the currently executing task is + do_config, the value is + "config". + + + + + BB_SCHEDULER + + + Selects the name of the scheduler to use for the + scheduling of BitBake tasks. + Three options exist: + + basic - + The basic framework from which everything derives. + Using this option causes tasks to be ordered + numerically as they are parsed. + + speed - + Executes tasks first that have more tasks + depending on them. + The "speed" option is the default. + + completion - + Causes the scheduler to try to complete a given + recipe once its build has started. + + + + + + + BB_SCHEDULERS + + + Defines custom schedulers to import. + Custom schedulers need to be derived from the + RunQueueScheduler class. + + + + For information how to select a scheduler, see the + BB_SCHEDULER + variable. + + + + + BB_SETSCENE_DEPVALID + + + Specifies a function BitBake calls that determines + whether BitBake requires a setscene dependency to be met. + + + + When running a setscene task, BitBake needs to + know which dependencies of that setscene task also need + to be run. + Whether dependencies also need to be run is highly + dependent on the metadata. + The function specified by this variable returns a + "True" or "False" depending on whether the dependency needs + to be met. + + + + + BB_SETSCENE_VERIFY_FUNCTION2 + + + Specifies a function to call that verifies the list of + planned task execution before the main task execution + happens. + The function is called once BitBake has a list of setscene + tasks that have run and either succeeded or failed. + + + + The function allows for a task list check to see if they + make sense. + Even if BitBake was planning to skip a task, the + returned value of the function can force BitBake to run + the task, which is necessary under certain metadata + defined circumstances. + + + + + BB_SIGNATURE_EXCLUDE_FLAGS + + + Lists variable flags (varflags) + that can be safely excluded from checksum + and dependency data for keys in the datastore. + When generating checksum or dependency data for keys in the + datastore, the flags set against that key are normally + included in the checksum. + + + + For more information on varflags, see the + "Variable Flags" + section. + + + + + BB_SIGNATURE_HANDLER + + + Defines the name of the signature handler BitBake uses. + The signature handler defines the way stamp files are + created and handled, if and how the signature is + incorporated into the stamps, and how the signature + itself is generated. + + + + A new signature handler can be added by injecting a class + derived from the + SignatureGenerator class into the + global namespace. + + + + + BB_SRCREV_POLICY + + + Defines the behavior of the fetcher when it interacts with + source control systems and dynamic source revisions. + The BB_SRCREV_POLICY variable is + useful when working without a network. + + + + The variable can be set using one of two policies: + + cache - + Retains the value the system obtained previously + rather than querying the source control system + each time. + + clear - + Queries the source controls system every time. + With this policy, there is no cache. + The "clear" policy is the default. + + + + + + + BB_STAMP_POLICY + + + Defines the mode used for how timestamps of stamp files + are compared. + You can set the variable to one of the following modes: + + perfile - + Timestamp comparisons are only made + between timestamps of a specific recipe. + This is the default mode. + + full - + Timestamp comparisons are made for all + dependencies. + + whitelist - + Identical to "full" mode except timestamp + comparisons are made for recipes listed in the + BB_STAMP_WHITELIST + variable. + + + + Stamp policies are largely obsolete with the + introduction of setscene tasks. + + + + + + BB_STAMP_WHITELIST + + + Lists files whose stamp file timestamps are compared when + the stamp policy mode is set to "whitelist". + For information on stamp policies, see the + BB_STAMP_POLICY + variable. + + + + + BB_STRICT_CHECKSUM + + + Sets a more strict checksum mechanism for non-local URLs. + Setting this variable to a value causes BitBake + to report an error if it encounters a non-local URL + that does not have at least one checksum specified. + + + + + BB_TASK_IONICE_LEVEL + + + Allows adjustment of a task's Input/Output priority. + During Autobuilder testing, random failures can occur + for tasks due to I/O starvation. + These failures occur during various QEMU runtime timeouts. + You can use the BB_TASK_IONICE_LEVEL + variable to adjust the I/O priority of these tasks. + + This variable works similarly to the + BB_TASK_NICE_LEVEL + variable except with a task's I/O priorities. + + + + + Set the variable as follows: + + BB_TASK_IONICE_LEVEL = "class.prio" + + For class, the default value is + "2", which is a best effort. + You can use "1" for realtime and "3" for idle. + If you want to use realtime, you must have superuser + privileges. + + + + For prio, you can use any + value from "0", which is the highest priority, to "7", + which is the lowest. + The default value is "4". + You do not need any special privileges to use this range + of priority values. + + In order for your I/O priority settings to take effect, + you need the Completely Fair Queuing (CFQ) Scheduler + selected for the backing block device. + To select the scheduler, use the following command form + where device is the device + (e.g. sda, sdb, and so forth): + + $ sudo sh -c “echo cfq > /sys/block/device/queu/scheduler + + + + + + + BB_TASK_NICE_LEVEL + + + Allows specific tasks to change their priority + (i.e. nice level). + + + + You can use this variable in combination with task + overrides to raise or lower priorities of specific tasks. + For example, on the + Yocto Project + autobuilder, QEMU emulation in images is given a higher + priority as compared to build tasks to ensure that images + do not suffer timeouts on loaded systems. + + + + + BB_TASKHASH + + + Within an executing task, this variable holds the hash + of the task as returned by the currently enabled + signature generator. + + + + + BB_VERBOSE_LOGS + + + Controls how verbose BitBake is during builds. + If set, shell scripts echo commands and shell script output + appears on standard out (stdout). + + + + + BB_WORKERCONTEXT + + + Specifies if the current context is executing a task. + BitBake sets this variable to "1" when a task is + being executed. + The value is not set when the task is in server context + during parsing or event handling. + + + + + + BBCLASSEXTEND + + + Allows you to extend a recipe so that it builds variants + of the software. + Some examples of these variants for recipes from the + OpenEmbedded-Core metadata are "natives" such as + quilt-native, which is a copy of + Quilt built to run on the build system; "crosses" such + as gcc-cross, which is a compiler + built to run on the build machine but produces binaries + that run on the target MACHINE; + "nativesdk", which targets the SDK machine instead of + MACHINE; and "mulitlibs" in the form + "multilib:multilib_name". + + + + To build a different variant of the recipe with a minimal + amount of code, it usually is as simple as adding the + variable to your recipe. + Here are two examples. + The "native" variants are from the OpenEmbedded-Core + metadata: + + BBCLASSEXTEND =+ "native nativesdk" + BBCLASSEXTEND =+ "multilib:multilib_name" + + + + Internally, the BBCLASSEXTEND + mechanism generates recipe variants by rewriting + variable values and applying overrides such as + _class-native. + For example, to generate a native version of a recipe, + a + DEPENDS + on "foo" is rewritten to a DEPENDS + on "foo-native". + + + + Even when using BBCLASSEXTEND, the + recipe is only parsed once. + Parsing once adds some limitations. + For example, it is not possible to + include a different file depending on the variant, + since include statements are + processed when the recipe is parsed. + + + + + + + BBDEBUG + + + Sets the BitBake debug output level to a specific value + as incremented by the -D command line + option. + + You must set this variable in the external environment + in order for it to work. + + + + + + BBFILE_COLLECTIONS + + Lists the names of configured layers. + These names are used to find the other BBFILE_* + variables. + Typically, each layer appends its name to this variable in its + conf/layer.conf file. + + + + + BBFILE_PATTERN + + Variable that expands to match files from + BBFILES + in a particular layer. + This variable is used in the conf/layer.conf file and must + be suffixed with the name of the specific layer (e.g. + BBFILE_PATTERN_emenlow). + + + + BBFILE_PRIORITY + + Assigns the priority for recipe files in each layer. + This variable is useful in situations where the same recipe appears in + more than one layer. + Setting this variable allows you to prioritize a + layer against other layers that contain the same recipe - effectively + letting you control the precedence for the multiple layers. + The precedence established through this variable stands regardless of a + recipe's version + (PV variable). + For example, a layer that has a recipe with a higher PV value but for + which the BBFILE_PRIORITY is set to have a lower precedence still has a + lower precedence. + A larger value for the BBFILE_PRIORITY variable results in a higher + precedence. + For example, the value 6 has a higher precedence than the value 5. + If not specified, the BBFILE_PRIORITY variable is set based on layer + dependencies (see the + LAYERDEPENDS variable for + more information. + The default priority, if unspecified + for a layer with no dependencies, is the lowest defined priority + 1 + (or 1 if no priorities are defined). + + You can use the command bitbake-layers show-layers to list + all configured layers along with their priorities. + + + + + BBFILES + + List of recipe files BitBake uses to build software. + + + + BBINCLUDED + + + Contains a space-separated list of all of all files that + BitBake's parser included during parsing of the current + file. + + + + + BBINCLUDELOGS + + + If set to a value, enables printing the task log when + reporting a failed task. + + + + + BBINCLUDELOGS_LINES + + + If + BBINCLUDELOGS + is set, specifies the maximum number of lines from the + task log file to print when reporting a failed task. + If you do not set BBINCLUDELOGS_LINES, + the entire log is printed. + + + + + BBLAYERS + + Lists the layers to enable during the build. + This variable is defined in the bblayers.conf configuration + file in the build directory. + Here is an example: + + BBLAYERS = " \ + /home/scottrif/poky/meta \ + /home/scottrif/poky/meta-yocto \ + /home/scottrif/poky/meta-yocto-bsp \ + /home/scottrif/poky/meta-mykernel \ + " + + + This example enables four layers, one of which is a custom, user-defined layer + named meta-mykernel. + + + + + BBLAYERS_FETCH_DIR + + + Sets the base location where layers are stored. + This setting is used in conjunction with + bitbake-layers layerindex-fetch and + tells bitbake-layers where to place + the fetched layers. + + + + + BBMASK + + + Prevents BitBake from processing recipes and recipe + append files. + + + + You can use the BBMASK variable + to "hide" these .bb and + .bbappend files. + BitBake ignores any recipe or recipe append files that + match any of the expressions. + It is as if BitBake does not see them at all. + Consequently, matching files are not parsed or otherwise + used by BitBake. + + The values you provide are passed to Python's regular + expression compiler. + The expressions are compared against the full paths to + the files. + For complete syntax information, see Python's + documentation at + . + + + + The following example uses a complete regular expression + to tell BitBake to ignore all recipe and recipe append + files in the meta-ti/recipes-misc/ + directory: + + BBMASK = "meta-ti/recipes-misc/" + + If you want to mask out multiple directories or recipes, + you can specify multiple regular expression fragments. + This next example masks out multiple directories and + individual recipes: + + BBMASK += "/meta-ti/recipes-misc/ meta-ti/recipes-ti/packagegroup/" + BBMASK += "/meta-oe/recipes-support/" + BBMASK += "/meta-foo/.*/openldap" + BBMASK += "opencv.*\.bbappend" + BBMASK += "lzma" + + + When specifying a directory name, use the trailing + slash character to ensure you match just that directory + name. + + + + + + BBPATH + + + Used by BitBake to locate class + (.bbclass) and configuration + (.conf) files. + This variable is analogous to the + PATH variable. + + + + If you run BitBake from a directory outside of the + build directory, + you must be sure to set + BBPATH to point to the + build directory. + Set the variable as you would any environment variable + and then run BitBake: + + $ BBPATH="build_directory" + $ export BBPATH + $ bitbake target + + + + + + BBSERVER + + + Points to the server that runs memory-resident BitBake. + The variable is only used when you employ memory-resident + BitBake. + + + + + BBTARGETS + + + Allows you to use a configuration file to add to the list + of command-line target recipes you want to build. + + + + + BBVERSIONS + + + Allows a single recipe to build multiple versions of a + project from a single recipe file. + You also able to specify conditional metadata + using the + OVERRIDES + mechanism for a single version or for an optionally named + range of versions. + + + + For more information on BBVERSIONS, + see the + "Variants - Class Extension Mechanism" + section. + + + + + BITBAKE_UI + + + Used to specify the UI module to use when running BitBake. + Using this variable is equivalent to using the + -u command-line option. + + You must set this variable in the external environment + in order for it to work. + + + + + + BUILDNAME + + + A name assigned to the build. + The name defaults to a datetime stamp of when the build was + started but can be defined by the metadata. + + + + + BZRDIR + + + The directory in which files checked out of a Bazaar + system are stored. + + + + + + + C + + CACHE + + + Specifies the directory BitBake uses to store a cache + of the metadata so it does not need to be parsed every + time BitBake is started. + + + + + CVSDIR + + + The directory in which files checked out under the + CVS system are stored. + + + + + + + D + + DEFAULT_PREFERENCE + + + Specifies a weak bias for recipe selection priority. + + + The most common usage of this is variable is to set + it to "-1" within a recipe for a development version of a + piece of software. + Using the variable in this way causes the stable version + of the recipe to build by default in the absence of + PREFERRED_VERSION + being used to build the development version. + + + The bias provided by DEFAULT_PREFERENCE + is weak and is overridden by + BBFILE_PRIORITY + if that variable is different between two layers + that contain different versions of the same recipe. + + + + + DEPENDS + + + Lists a recipe's build-time dependencies + (i.e. other recipe files). + + + + Consider this simple example for two recipes named "a" and + "b" that produce similarly named packages. + In this example, the DEPENDS + statement appears in the "a" recipe: + + DEPENDS = "b" + + Here, the dependency is such that the + do_configure task for recipe "a" + depends on the do_populate_sysroot + task of recipe "b". + This means anything that recipe "b" puts into sysroot + is available when recipe "a" is configuring itself. + + + + For information on runtime dependencies, see the + RDEPENDS + variable. + + + + + DESCRIPTION + + + A long description for the recipe. + + + + + DL_DIR + + + The central download directory used by the build process to + store downloads. + By default, DL_DIR gets files + suitable for mirroring for everything except Git + repositories. + If you want tarballs of Git repositories, use the + BB_GENERATE_MIRROR_TARBALLS + variable. + + + + + + + E + + EXCLUDE_FROM_WORLD + + + Directs BitBake to exclude a recipe from world builds (i.e. + bitbake world). + During world builds, BitBake locates, parses and builds all + recipes found in every layer exposed in the + bblayers.conf configuration file. + + + + To exclude a recipe from a world build using this variable, + set the variable to "1" in the recipe. + + + + Recipes added to EXCLUDE_FROM_WORLD + may still be built during a world build in order to satisfy + dependencies of other recipes. + Adding a recipe to EXCLUDE_FROM_WORLD + only ensures that the recipe is not explicitly added + to the list of build targets in a world build. + + + + + + + F + + FAKEROOT + + + Contains the command to use when running a shell script + in a fakeroot environment. + The FAKEROOT variable is obsolete + and has been replaced by the other + FAKEROOT* variables. + See these entries in the glossary for more information. + + + + + FAKEROOTBASEENV + + + Lists environment variables to set when executing + the command defined by + FAKEROOTCMD + that starts the bitbake-worker process + in the fakeroot environment. + + + + + FAKEROOTCMD + + + Contains the command that starts the bitbake-worker + process in the fakeroot environment. + + + + + FAKEROOTDIRS + + + Lists directories to create before running a task in + the fakeroot environment. + + + + + FAKEROOTENV + + + Lists environment variables to set when running a task + in the fakeroot environment. + For additional information on environment variables and + the fakeroot environment, see the + FAKEROOTBASEENV + variable. + + + + + FAKEROOTNOENV + + + Lists environment variables to set when running a task + that is not in the fakeroot environment. + For additional information on environment variables and + the fakeroot environment, see the + FAKEROOTENV + variable. + + + + + FETCHCMD + + + Defines the command the BitBake fetcher module + executes when running fetch operations. + You need to use an override suffix when you use the + variable (e.g. FETCHCMD_git + or FETCHCMD_svn). + + + + + FILE + + + Points at the current file. + BitBake sets this variable during the parsing process + to identify the file being parsed. + BitBake also sets this variable when a recipe is being + executed to identify the recipe file. + + + + + FILESPATH + + + Specifies directories BitBake uses when searching for + patches and files. + The "local" fetcher module uses these directories when + handling file:// URLs. + The variable behaves like a shell PATH + environment variable. + The value is a colon-separated list of directories that + are searched left-to-right in order. + + + + + + + + G + + GITDIR + + + The directory in which a local copy of a Git repository + is stored when it is cloned. + + + + + + + + H + + HGDIR + + + The directory in which files checked out of a Mercurial + system are stored. + + + + + HOMEPAGE + + Website where more information about the software the recipe is building + can be found. + + + + + + I + + INHERIT + + + Causes the named class or classes to be inherited globally. + Anonymous functions in the class or classes + are not executed for the + base configuration and in each individual recipe. + The OpenEmbedded build system ignores changes to + INHERIT in individual recipes. + + + + For more information on INHERIT, see + the + "INHERIT Configuration Directive" + section. + + + + + + + + + L + + LAYERDEPENDS + + Lists the layers, separated by spaces, upon which this recipe depends. + Optionally, you can specify a specific layer version for a dependency + by adding it to the end of the layer name with a colon, (e.g. "anotherlayer:3" + to be compared against + LAYERVERSION_anotherlayer + in this case). + BitBake produces an error if any dependency is missing or + the version numbers do not match exactly (if specified). + + You use this variable in the conf/layer.conf file. + You must also use the specific layer name as a suffix + to the variable (e.g. LAYERDEPENDS_mylayer). + + + + LAYERDIR + + When used inside the layer.conf configuration + file, this variable provides the path of the current layer. + This variable is not available outside of layer.conf + and references are expanded immediately when parsing of the file completes. + + + + LAYERDIR_RE + + When used inside the layer.conf configuration + file, this variable provides the path of the current layer, + escaped for use in a regular expression + (BBFILE_PATTERN). + This variable is not available outside of layer.conf + and references are expanded immediately when parsing of the file completes. + + + + LAYERVERSION + + Optionally specifies the version of a layer as a single number. + You can use this variable within + LAYERDEPENDS + for another layer in order to depend on a specific version + of the layer. + + You use this variable in the conf/layer.conf file. + You must also use the specific layer name as a suffix + to the variable (e.g. LAYERDEPENDS_mylayer). + + + + LICENSE + + + The list of source licenses for the recipe. + + + + + + + M + + MIRRORS + + + Specifies additional paths from which BitBake gets source code. + When the build system searches for source code, it first + tries the local download directory. + If that location fails, the build system tries locations + defined by + PREMIRRORS, + the upstream source, and then locations specified by + MIRRORS in that order. + + + + + MULTI_PROVIDER_WHITELIST + + + Allows you to suppress BitBake warnings caused when + building two separate recipes that provide the same + output. + + + + Bitbake normally issues a warning when building two + different recipes where each provides the same output. + This scenario is usually something the user does not + want. + However, cases do exist where it makes sense, particularly + in the virtual/* namespace. + You can use this variable to suppress BitBake's warnings. + + + + To use the variable, list provider names (e.g. + recipe names, virtual/kernel, + and so forth). + + + + + + + + + O + + OVERRIDES + + + BitBake uses OVERRIDES to control + what variables are overridden after BitBake parses + recipes and configuration files. + + + + Following is a simple example that uses an overrides + list based on machine architectures: + + OVERRIDES = "arm:x86:mips:powerpc" + + You can find information on how to use + OVERRIDES in the + "Conditional Syntax (Overrides)" + section. + + + + + + P + + P4DIR + + + The directory in which a local copy of a Perforce depot + is stored when it is fetched. + + + + + PACKAGES + + The list of packages the recipe creates. + + + + + PACKAGES_DYNAMIC + + + A promise that your recipe satisfies runtime dependencies + for optional modules that are found in other recipes. + PACKAGES_DYNAMIC + does not actually satisfy the dependencies, it only states that + they should be satisfied. + For example, if a hard, runtime dependency + (RDEPENDS) + of another package is satisfied during the build + through the PACKAGES_DYNAMIC + variable, but a package with the module name is never actually + produced, then the other package will be broken. + + + + + PE + + + The epoch of the recipe. + By default, this variable is unset. + The variable is used to make upgrades possible when the + versioning scheme changes in some backwards incompatible + way. + + + + + PERSISTENT_DIR + + + Specifies the directory BitBake uses to store data that + should be preserved between builds. + In particular, the data stored is the data that uses + BitBake's persistent data API and the data used by the + PR Server and PR Service. + + + + + PF + + + Specifies the recipe or package name and includes all version and revision + numbers (i.e. eglibc-2.13-r20+svnr15508/ and + bash-4.2-r1/). + + + + + PN + + The recipe name. + + + + PR + + The revision of the recipe. + + + + + PREFERRED_PROVIDER + + + Determines which recipe should be given preference when + multiple recipes provide the same item. + You should always suffix the variable with the name of the + provided item, and you should set it to the + PN + of the recipe to which you want to give precedence. + Some examples: + + PREFERRED_PROVIDER_virtual/kernel ?= "linux-yocto" + PREFERRED_PROVIDER_virtual/xserver = "xserver-xf86" + PREFERRED_PROVIDER_virtual/libgl ?= "mesa" + + + + + + PREFERRED_PROVIDERS + + + Determines which recipe should be given preference for + cases where multiple recipes provide the same item. + Functionally, + PREFERRED_PROVIDERS is identical to + PREFERRED_PROVIDER. + However, the PREFERRED_PROVIDERS + variable lets you define preferences for multiple + situations using the following form: + + PREFERRED_PROVIDERS = "xxx:yyy aaa:bbb ..." + + This form is a convenient replacement for the following: + + PREFERRED_PROVIDER_xxx = "yyy" + PREFERRED_PROVIDER_aaa = "bbb" + + + + + + PREFERRED_VERSION + + + If there are multiple versions of recipes available, this + variable determines which recipe should be given preference. + You must always suffix the variable with the + PN + you want to select, and you should set + PV + accordingly for precedence. + You can use the "%" character as a + wildcard to match any number of characters, which can be + useful when specifying versions that contain long revision + numbers that could potentially change. + Here are two examples: + + PREFERRED_VERSION_python = "2.7.3" + PREFERRED_VERSION_linux-yocto = "4.12%" + + + + + + PREMIRRORS + + + Specifies additional paths from which BitBake gets source code. + When the build system searches for source code, it first + tries the local download directory. + If that location fails, the build system tries locations + defined by PREMIRRORS, the upstream + source, and then locations specified by + MIRRORS + in that order. + + + + Typically, you would add a specific server for the + build system to attempt before any others by adding + something like the following to your configuration: + + PREMIRRORS_prepend = "\ + git://.*/.* http://www.yoctoproject.org/sources/ \n \ + ftp://.*/.* http://www.yoctoproject.org/sources/ \n \ + http://.*/.* http://www.yoctoproject.org/sources/ \n \ + https://.*/.* http://www.yoctoproject.org/sources/ \n" + + These changes cause the build system to intercept + Git, FTP, HTTP, and HTTPS requests and direct them to + the http:// sources mirror. + You can use file:// URLs to point + to local directories or network shares as well. + + + + + PROVIDES + + + A list of aliases by which a particular recipe can be + known. + By default, a recipe's own + PN + is implicitly already in its PROVIDES + list. + If a recipe uses PROVIDES, the + additional aliases are synonyms for the recipe and can + be useful satisfying dependencies of other recipes during + the build as specified by + DEPENDS. + + + + Consider the following example + PROVIDES statement from a recipe + file libav_0.8.11.bb: + + PROVIDES += "libpostproc" + + The PROVIDES statement results in + the "libav" recipe also being known as "libpostproc". + + + + In addition to providing recipes under alternate names, + the PROVIDES mechanism is also used + to implement virtual targets. + A virtual target is a name that corresponds to some + particular functionality (e.g. a Linux kernel). + Recipes that provide the functionality in question list the + virtual target in PROVIDES. + Recipes that depend on the functionality in question can + include the virtual target in + DEPENDS + to leave the choice of provider open. + + + + Conventionally, virtual targets have names on the form + "virtual/function" (e.g. "virtual/kernel"). + The slash is simply part of the name and has no + syntactical significance. + + + + + PRSERV_HOST + + + The network based + PR + service host and port. + + + + Following is an example of how the PRSERV_HOST variable is + set: + + PRSERV_HOST = "localhost:0" + + You must set the variable if you want to automatically + start a local PR service. + You can set PRSERV_HOST to other + values to use a remote PR service. + + + + + PV + + The version of the recipe. + + + + + + + + + R + + RDEPENDS + + + Lists a package's runtime dependencies (i.e. other packages) + that must be installed in order for the built package to run + correctly. + If a package in this list cannot be found during the build, + you will get a build error. + + + + Because the RDEPENDS variable applies + to packages being built, you should always use the variable + in a form with an attached package name. + For example, suppose you are building a development package + that depends on the perl package. + In this case, you would use the following + RDEPENDS statement: + + RDEPENDS_${PN}-dev += "perl" + + In the example, the development package depends on + the perl package. + Thus, the RDEPENDS variable has the + ${PN}-dev package name as part of the + variable. + + + + BitBake supports specifying versioned dependencies. + Although the syntax varies depending on the packaging + format, BitBake hides these differences from you. + Here is the general syntax to specify versions with + the RDEPENDS variable: + + RDEPENDS_${PN} = "package (operator version)" + + For operator, you can specify the + following: + + = + < + > + <= + >= + + For example, the following sets up a dependency on version + 1.2 or greater of the package foo: + + RDEPENDS_${PN} = "foo (>= 1.2)" + + + + + For information on build-time dependencies, see the + DEPENDS + variable. + + + + + REPODIR + + + The directory in which a local copy of a + google-repo directory is stored + when it is synced. + + + + + RPROVIDES + + + A list of package name aliases that a package also provides. + These aliases are useful for satisfying runtime dependencies + of other packages both during the build and on the target + (as specified by + RDEPENDS). + + + As with all package-controlling variables, you must always + use the variable in conjunction with a package name override. + Here is an example: + + RPROVIDES_${PN} = "widget-abi-2" + + + + + + RRECOMMENDS + + + A list of packages that extends the usability of a package + being built. + The package being built does not depend on this list of + packages in order to successfully build, but needs them for + the extended usability. + To specify runtime dependencies for packages, see the + RDEPENDS + variable. + + + + BitBake supports specifying versioned recommends. + Although the syntax varies depending on the packaging + format, BitBake hides these differences from you. + Here is the general syntax to specify versions with + the RRECOMMENDS variable: + + RRECOMMENDS_${PN} = "package (operator version)" + + For operator, you can specify the + following: + + = + < + > + <= + >= + + For example, the following sets up a recommend on version + 1.2 or greater of the package foo: + + RRECOMMENDS_${PN} = "foo (>= 1.2)" + + + + + + + + S + + SECTION + + The section in which packages should be categorized. + + + + SRC_URI + + + The list of source files - local or remote. + This variable tells BitBake which bits + to pull for the build and how to pull them. + For example, if the recipe or append file needs to + fetch a single tarball from the Internet, the recipe or + append file uses a SRC_URI + entry that specifies that tarball. + On the other hand, if the recipe or append file needs to + fetch a tarball and include a custom file, the recipe or + append file needs an SRC_URI variable + that specifies all those sources. + The following list explains the available URI protocols: + + file:// - + Fetches files, which are usually files shipped with + the metadata, + from the local machine. + The path is relative to the + FILESPATH + variable. + bzr:// - Fetches files from a + Bazaar revision control repository. + git:// - Fetches files from a + Git revision control repository. + osc:// - Fetches files from + an OSC (OpenSUSE Build service) revision control repository. + repo:// - Fetches files from + a repo (Git) repository. + http:// - Fetches files from + the Internet using HTTP. + https:// - Fetches files + from the Internet using HTTPS. + ftp:// - Fetches files + from the Internet using FTP. + cvs:// - Fetches files from + a CVS revision control repository. + hg:// - Fetches files from + a Mercurial (hg) revision control repository. + p4:// - Fetches files from + a Perforce (p4) revision control repository. + ssh:// - Fetches files from + a secure shell. + svn:// - Fetches files from + a Subversion (svn) revision control repository. + + + Here are some additional options worth mentioning: + + unpack - Controls + whether or not to unpack the file if it is an archive. + The default action is to unpack the file. + subdir - Places the file + (or extracts its contents) into the specified + subdirectory. + This option is useful for unusual tarballs or other archives that + do not have their files already in a subdirectory within the archive. + + name - Specifies a + name to be used for association with SRC_URI checksums + when you have more than one file specified in SRC_URI. + + downloadfilename - Specifies + the filename used when storing the downloaded file. + + + + + + SRCDATE + + + The date of the source code used to build the package. + This variable applies only if the source was fetched from a Source Code Manager (SCM). + + + + + SRCREV + + + The revision of the source code used to build the package. + This variable applies only when using Subversion, Git, Mercurial and Bazaar. + If you want to build a fixed revision and you want + to avoid performing a query on the remote repository every time + BitBake parses your recipe, you should specify a SRCREV that is a + full revision identifier and not just a tag. + + + + + SRCREV_FORMAT + + + Helps construct valid + SRCREV + values when multiple source controlled URLs are used in + SRC_URI. + + + + The system needs help constructing these values under these + circumstances. + Each component in the SRC_URI + is assigned a name and these are referenced + in the SRCREV_FORMAT variable. + Consider an example with URLs named "machine" and "meta". + In this case, SRCREV_FORMAT could look + like "machine_meta" and those names would have the SCM + versions substituted into each position. + Only one AUTOINC placeholder is added + and if needed. + And, this placeholder is placed at the start of the + returned string. + + + + + STAMP + + + Specifies the base path used to create recipe stamp files. + The path to an actual stamp file is constructed by evaluating this + string and then appending additional information. + + + + + STAMPCLEAN + + + Specifies the base path used to create recipe stamp files. + Unlike the + STAMP + variable, STAMPCLEAN can contain + wildcards to match the range of files a clean operation + should remove. + BitBake uses a clean operation to remove any other stamps + it should be removing when creating a new stamp. + + + + + SUMMARY + + + A short summary for the recipe, which is 72 characters or less. + + + + + SVNDIR + + + The directory in which files checked out of a Subversion + system are stored. + + + + + + + T + + T + + Points to a directory were BitBake places + temporary files, which consist mostly of task logs and + scripts, when building a particular recipe. + + + + + TOPDIR + + + Points to the build directory. + BitBake automatically sets this variable. + + + + + + + + + + + + diff --git

[bug=1227016] + +* Fixed a crash when a short input contains data not valid in + filenames. [bug=1232604] + +* Fixed a bug that caused Unicode data put into UnicodeDammit to + return None instead of the original data. [bug=1214983] + +* Combined two tests to stop a spurious test failure when tests are + run by nosetests. [bug=1212445] + += 4.3.1 (20130815) = + +* Fixed yet another problem with the html5lib tree builder, caused by + html5lib's tendency to rearrange the tree during + parsing. [bug=1189267] + +* Fixed a bug that caused the optimized version of find_all() to + return nothing. [bug=1212655] + += 4.3.0 (20130812) = + +* Instead of converting incoming data to Unicode and feeding it to the + lxml tree builder in chunks, Beautiful Soup now makes successive + guesses at the encoding of the incoming data, and tells lxml to + parse the data as that encoding. Giving lxml more control over the + parsing process improves performance and avoids a number of bugs and + issues with the lxml parser which had previously required elaborate + workarounds: + + - An issue in which lxml refuses to parse Unicode strings on some + systems. [bug=1180527] + + - A returning bug that truncated documents longer than a (very + small) size. [bug=963880] + + - A returning bug in which extra spaces were added to a document if + the document defined a charset other than UTF-8. [bug=972466] + + This required a major overhaul of the tree builder architecture. If + you wrote your own tree builder and didn't tell me, you'll need to + modify your prepare_markup() method. + +* The UnicodeDammit code that makes guesses at encodings has been + split into its own class, EncodingDetector. A lot of apparently + redundant code has been removed from Unicode, Dammit, and some + undocumented features have also been removed. + +* Beautiful Soup will issue a warning if instead of markup you pass it + a URL or the name of a file on disk (a common beginner's mistake). + +* A number of optimizations improve the performance of the lxml tree + builder by about 33%, the html.parser tree builder by about 20%, and + the html5lib tree builder by about 15%. + +* All find_all calls should now return a ResultSet object. Patch by + Aaron DeVore. [bug=1194034] + += 4.2.1 (20130531) = + +* The default XML formatter will now replace ampersands even if they + appear to be part of entities. That is, "<" will become + "&lt;". The old code was left over from Beautiful Soup 3, which + didn't always turn entities into Unicode characters. + + If you really want the old behavior (maybe because you add new + strings to the tree, those strings include entities, and you want + the formatter to leave them alone on output), it can be found in + EntitySubstitution.substitute_xml_containing_entities(). [bug=1182183] + +* Gave new_string() the ability to create subclasses of + NavigableString. [bug=1181986] + +* Fixed another bug by which the html5lib tree builder could create a + disconnected tree. [bug=1182089] + +* The .previous_element of a BeautifulSoup object is now always None, + not the last element to be parsed. [bug=1182089] + +* Fixed test failures when lxml is not installed. [bug=1181589] + +* html5lib now supports Python 3. Fixed some Python 2-specific + code in the html5lib test suite. [bug=1181624] + +* The html.parser treebuilder can now handle numeric attributes in + text when the hexidecimal name of the attribute starts with a + capital X. Patch by Tim Shirley. [bug=1186242] + += 4.2.0 (20130514) = + +* The Tag.select() method now supports a much wider variety of CSS + selectors. + + - Added support for the adjacent sibling combinator (+) and the + general sibling combinator (~). Tests by "liquider". [bug=1082144] + + - The combinators (>, +, and ~) can now combine with any supported + selector, not just one that selects based on tag name. + + - Added limited support for the "nth-of-type" pseudo-class. Code + by Sven Slootweg. [bug=1109952] + +* The BeautifulSoup class is now aliased to "_s" and "_soup", making + it quicker to type the import statement in an interactive session: + + from bs4 import _s + or + from bs4 import _soup + + The alias may change in the future, so don't use this in code you're + going to run more than once. + +* Added the 'diagnose' submodule, which includes several useful + functions for reporting problems and doing tech support. + + - diagnose(data) tries the given markup on every installed parser, + reporting exceptions and displaying successes. If a parser is not + installed, diagnose() mentions this fact. + + - lxml_trace(data, html=True) runs the given markup through lxml's + XML parser or HTML parser, and prints out the parser events as + they happen. This helps you quickly determine whether a given + problem occurs in lxml code or Beautiful Soup code. + + - htmlparser_trace(data) is the same thing, but for Python's + built-in HTMLParser class. + +* In an HTML document, the contents of a <script> or <style> tag will + no longer undergo entity substitution by default. XML documents work + the same way they did before. [bug=1085953] + +* Methods like get_text() and properties like .strings now only give + you strings that are visible in the document--no comments or + processing commands. [bug=1050164] + +* The prettify() method now leaves the contents of <pre> tags + alone. [bug=1095654] + +* Fix a bug in the html5lib treebuilder which sometimes created + disconnected trees. [bug=1039527] + +* Fix a bug in the lxml treebuilder which crashed when a tag included + an attribute from the predefined "xml:" namespace. [bug=1065617] + +* Fix a bug by which keyword arguments to find_parent() were not + being passed on. [bug=1126734] + +* Stop a crash when unwisely messing with a tag that's been + decomposed. [bug=1097699] + +* Now that lxml's segfault on invalid doctype has been fixed, fixed a + corresponding problem on the Beautiful Soup end that was previously + invisible. [bug=984936] + +* Fixed an exception when an overspecified CSS selector didn't match + anything. Code by Stefaan Lippens. [bug=1168167] + += 4.1.3 (20120820) = + +* Skipped a test under Python 2.6 and Python 3.1 to avoid a spurious + test failure caused by the lousy HTMLParser in those + versions. [bug=1038503] + +* Raise a more specific error (FeatureNotFound) when a requested + parser or parser feature is not installed. Raise NotImplementedError + instead of ValueError when the user calls insert_before() or + insert_after() on the BeautifulSoup object itself. Patch by Aaron + Devore. [bug=1038301] + += 4.1.2 (20120817) = + +* As per PEP-8, allow searching by CSS class using the 'class_' + keyword argument. [bug=1037624] + +* Display namespace prefixes for namespaced attribute names, instead of + the fully-qualified names given by the lxml parser. [bug=1037597] + +* Fixed a crash on encoding when an attribute name contained + non-ASCII characters. + +* When sniffing encodings, if the cchardet library is installed, + Beautiful Soup uses it instead of chardet. cchardet is much + faster. [bug=1020748] + +* Use logging.warning() instead of warning.warn() to notify the user + that characters were replaced with REPLACEMENT + CHARACTER. [bug=1013862] + += 4.1.1 (20120703) = + +* Fixed an html5lib tree builder crash which happened when html5lib + moved a tag with a multivalued attribute from one part of the tree + to another. [bug=1019603] + +* Correctly display closing tags with an XML namespace declared. Patch + by Andreas Kostyrka. [bug=1019635] + +* Fixed a typo that made parsing significantly slower than it should + have been, and also waited too long to close tags with XML + namespaces. [bug=1020268] + +* get_text() now returns an empty Unicode string if there is no text, + rather than an empty bytestring. [bug=1020387] + += 4.1.0 (20120529) = + +* Added experimental support for fixing Windows-1252 characters + embedded in UTF-8 documents. (UnicodeDammit.detwingle()) + +* Fixed the handling of " with the built-in parser. [bug=993871] + +* Comments, processing instructions, document type declarations, and + markup declarations are now treated as preformatted strings, the way + CData blocks are. [bug=1001025] + +* Fixed a bug with the lxml treebuilder that prevented the user from + adding attributes to a tag that didn't originally have + attributes. [bug=1002378] Thanks to Oliver Beattie for the patch. + +* Fixed some edge-case bugs having to do with inserting an element + into a tag it's already inside, and replacing one of a tag's + children with another. [bug=997529] + +* Added the ability to search for attribute values specified in UTF-8. [bug=1003974] + + This caused a major refactoring of the search code. All the tests + pass, but it's possible that some searches will behave differently. + += 4.0.5 (20120427) = + +* Added a new method, wrap(), which wraps an element in a tag. + +* Renamed replace_with_children() to unwrap(), which is easier to + understand and also the jQuery name of the function. + +* Made encoding substitution in <meta> tags completely transparent (no + more %SOUP-ENCODING%). + +* Fixed a bug in decoding data that contained a byte-order mark, such + as data encoded in UTF-16LE. [bug=988980] + +* Fixed a bug that made the HTMLParser treebuilder generate XML + definitions ending with two question marks instead of + one. [bug=984258] + +* Upon document generation, CData objects are no longer run through + the formatter. [bug=988905] + +* The test suite now passes when lxml is not installed, whether or not + html5lib is installed. [bug=987004] + +* Print a warning on HTMLParseErrors to let people know they should + install a better parser library. + += 4.0.4 (20120416) = + +* Fixed a bug that sometimes created disconnected trees. + +* Fixed a bug with the string setter that moved a string around the + tree instead of copying it. [bug=983050] + +* Attribute values are now run through the provided output formatter. + Previously they were always run through the 'minimal' formatter. In + the future I may make it possible to specify different formatters + for attribute values and strings, but for now, consistent behavior + is better than inconsistent behavior. [bug=980237] + +* Added the missing renderContents method from Beautiful Soup 3. Also + added an encode_contents() method to go along with decode_contents(). + +* Give a more useful error when the user tries to run the Python 2 + version of BS under Python 3. + +* UnicodeDammit can now convert Microsoft smart quotes to ASCII with + UnicodeDammit(markup, smart_quotes_to="ascii"). + += 4.0.3 (20120403) = + +* Fixed a typo that caused some versions of Python 3 to convert the + Beautiful Soup codebase incorrectly. + +* Got rid of the 4.0.2 workaround for HTML documents--it was + unnecessary and the workaround was triggering a (possibly different, + but related) bug in lxml. [bug=972466] + += 4.0.2 (20120326) = + +* Worked around a possible bug in lxml that prevents non-tiny XML + documents from being parsed. [bug=963880, bug=963936] + +* Fixed a bug where specifying `text` while also searching for a tag + only worked if `text` wanted an exact string match. [bug=955942] + += 4.0.1 (20120314) = + +* This is the first official release of Beautiful Soup 4. There is no + 4.0.0 release, to eliminate any possibility that packaging software + might treat "4.0.0" as being an earlier version than "4.0.0b10". + +* Brought BS up to date with the latest release of soupselect, adding + CSS selector support for direct descendant matches and multiple CSS + class matches. + += 4.0.0b10 (20120302) = + +* Added support for simple CSS selectors, taken from the soupselect project. + +* Fixed a crash when using html5lib. [bug=943246] + +* In HTML5-style <meta charset="foo"> tags, the value of the "charset" + attribute is now replaced with the appropriate encoding on + output. [bug=942714] + +* Fixed a bug that caused calling a tag to sometimes call find_all() + with the wrong arguments. [bug=944426] + +* For backwards compatibility, brought back the BeautifulStoneSoup + class as a deprecated wrapper around BeautifulSoup. + += 4.0.0b9 (20120228) = + +* Fixed the string representation of DOCTYPEs that have both a public + ID and a system ID. + +* Fixed the generated XML declaration. + +* Renamed Tag.nsprefix to Tag.prefix, for consistency with + NamespacedAttribute. + +* Fixed a test failure that occured on Python 3.x when chardet was + installed. + +* Made prettify() return Unicode by default, so it will look nice on + Python 3 when passed into print(). + += 4.0.0b8 (20120224) = + +* All tree builders now preserve namespace information in the + documents they parse. If you use the html5lib parser or lxml's XML + parser, you can access the namespace URL for a tag as tag.namespace. + + However, there is no special support for namespace-oriented + searching or tree manipulation. When you search the tree, you need + to use namespace prefixes exactly as they're used in the original + document. + +* The string representation of a DOCTYPE always ends in a newline. + +* Issue a warning if the user tries to use a SoupStrainer in + conjunction with the html5lib tree builder, which doesn't support + them. + += 4.0.0b7 (20120223) = + +* Upon decoding to string, any characters that can't be represented in + your chosen encoding will be converted into numeric XML entity + references. + +* Issue a warning if characters were replaced with REPLACEMENT + CHARACTER during Unicode conversion. + +* Restored compatibility with Python 2.6. + +* The install process no longer installs docs or auxillary text files. + +* It's now possible to deepcopy a BeautifulSoup object created with + Python's built-in HTML parser. + +* About 100 unit tests that "test" the behavior of various parsers on + invalid markup have been removed. Legitimate changes to those + parsers caused these tests to fail, indicating that perhaps + Beautiful Soup should not test the behavior of foreign + libraries. + + The problematic unit tests have been reformulated as informational + comparisons generated by the script + scripts/demonstrate_parser_differences.py. + + This makes Beautiful Soup compatible with html5lib version 0.95 and + future versions of HTMLParser. + += 4.0.0b6 (20120216) = + +* Multi-valued attributes like "class" always have a list of values, + even if there's only one value in the list. + +* Added a number of multi-valued attributes defined in HTML5. + +* Stopped generating a space before the slash that closes an + empty-element tag. This may come back if I add a special XHTML mode + (http://www.w3.org/TR/xhtml1/#C_2), but right now it's pretty + useless. + +* Passing text along with tag-specific arguments to a find* method: + + find("a", text="Click here") + + will find tags that contain the given text as their + .string. Previously, the tag-specific arguments were ignored and + only strings were searched. + +* Fixed a bug that caused the html5lib tree builder to build a + partially disconnected tree. Generally cleaned up the html5lib tree + builder. + +* If you restrict a multi-valued attribute like "class" to a string + that contains spaces, Beautiful Soup will only consider it a match + if the values correspond to that specific string. + += 4.0.0b5 (20120209) = + +* Rationalized Beautiful Soup's treatment of CSS class. A tag + belonging to multiple CSS classes is treated as having a list of + values for the 'class' attribute. Searching for a CSS class will + match *any* of the CSS classes. + + This actually affects all attributes that the HTML standard defines + as taking multiple values (class, rel, rev, archive, accept-charset, + and headers), but 'class' is by far the most common. [bug=41034] + +* If you pass anything other than a dictionary as the second argument + to one of the find* methods, it'll assume you want to use that + object to search against a tag's CSS classes. Previously this only + worked if you passed in a string. + +* Fixed a bug that caused a crash when you passed a dictionary as an + attribute value (possibly because you mistyped "attrs"). [bug=842419] + +* Unicode, Dammit now detects the encoding in HTML 5-style <meta> tags + like <meta charset="utf-8" />. [bug=837268] + +* If Unicode, Dammit can't figure out a consistent encoding for a + page, it will try each of its guesses again, with errors="replace" + instead of errors="strict". This may mean that some data gets + replaced with REPLACEMENT CHARACTER, but at least most of it will + get turned into Unicode. [bug=754903] + +* Patched over a bug in html5lib (?) that was crashing Beautiful Soup + on certain kinds of markup. [bug=838800] + +* Fixed a bug that wrecked the tree if you replaced an element with an + empty string. [bug=728697] + +* Improved Unicode, Dammit's behavior when you give it Unicode to + begin with. + += 4.0.0b4 (20120208) = + +* Added BeautifulSoup.new_string() to go along with BeautifulSoup.new_tag() + +* BeautifulSoup.new_tag() will follow the rules of whatever + tree-builder was used to create the original BeautifulSoup object. A + new <p> tag will look like "<p />" if the soup object was created to + parse XML, but it will look like "<p></p>" if the soup object was + created to parse HTML. + +* We pass in strict=False to html.parser on Python 3, greatly + improving html.parser's ability to handle bad HTML. + +* We also monkeypatch a serious bug in html.parser that made + strict=False disastrous on Python 3.2.2. + +* Replaced the "substitute_html_entities" argument with the + more general "formatter" argument. + +* Bare ampersands and angle brackets are always converted to XML + entities unless the user prevents it. + +* Added PageElement.insert_before() and PageElement.insert_after(), + which let you put an element into the parse tree with respect to + some other element. + +* Raise an exception when the user tries to do something nonsensical + like insert a tag into itself. + + += 4.0.0b3 (20120203) = + +Beautiful Soup 4 is a nearly-complete rewrite that removes Beautiful +Soup's custom HTML parser in favor of a system that lets you write a +little glue code and plug in any HTML or XML parser you want. + +Beautiful Soup 4.0 comes with glue code for four parsers: + + * Python's standard HTMLParser (html.parser in Python 3) + * lxml's HTML and XML parsers + * html5lib's HTML parser + +HTMLParser is the default, but I recommend you install lxml if you +can. + +For complete documentation, see the Sphinx documentation in +bs4/doc/source/. What follows is a summary of the changes from +Beautiful Soup 3. + +=== The module name has changed === + +Previously you imported the BeautifulSoup class from a module also +called BeautifulSoup. To save keystrokes and make it clear which +version of the API is in use, the module is now called 'bs4': + + >>> from bs4 import BeautifulSoup + +=== It works with Python 3 === + +Beautiful Soup 3.1.0 worked with Python 3, but the parser it used was +so bad that it barely worked at all. Beautiful Soup 4 works with +Python 3, and since its parser is pluggable, you don't sacrifice +quality. + +Special thanks to Thomas Kluyver and Ezio Melotti for getting Python 3 +support to the finish line. Ezio Melotti is also to thank for greatly +improving the HTML parser that comes with Python 3.2. + +=== CDATA sections are normal text, if they're understood at all. === + +Currently, the lxml and html5lib HTML parsers ignore CDATA sections in +markup: + + <p><![CDATA[foo]]></p> => <p></p> + +A future version of html5lib will turn CDATA sections into text nodes, +but only within tags like <svg> and <math>: + + <svg><![CDATA[foo]]></svg> => <p>foo</p> + +The default XML parser (which uses lxml behind the scenes) turns CDATA +sections into ordinary text elements: + + <p><![CDATA[foo]]></p> => <p>foo</p> + +In theory it's possible to preserve the CDATA sections when using the +XML parser, but I don't see how to get it to work in practice. + +=== Miscellaneous other stuff === + +If the BeautifulSoup instance has .is_xml set to True, an appropriate +XML declaration will be emitted when the tree is transformed into a +string: + + <?xml version="1.0" encoding="utf-8"> + <markup> + ... + </markup> + +The ['lxml', 'xml'] tree builder sets .is_xml to True; the other tree +builders set it to False. If you want to parse XHTML with an HTML +parser, you can set it manually. + + += 3.2.0 = + +The 3.1 series wasn't very useful, so I renamed the 3.0 series to 3.2 +to make it obvious which one you should use. + += 3.1.0 = + +A hybrid version that supports 2.4 and can be automatically converted +to run under Python 3.0. There are three backwards-incompatible +changes you should be aware of, but no new features or deliberate +behavior changes. + +1. str() may no longer do what you want. This is because the meaning +of str() inverts between Python 2 and 3; in Python 2 it gives you a +byte string, in Python 3 it gives you a Unicode string. + +The effect of this is that you can't pass an encoding to .__str__ +anymore. Use encode() to get a string and decode() to get Unicode, and +you'll be ready (well, readier) for Python 3. + +2. Beautiful Soup is now based on HTMLParser rather than SGMLParser, +which is gone in Python 3. There's some bad HTML that SGMLParser +handled but HTMLParser doesn't, usually to do with attribute values +that aren't closed or have brackets inside them: + + <a href="foo</a>, </a><a href="bar">baz</a> + <a b="<a>">', '<a b="<a>"></a><a>"></a> + +A later version of Beautiful Soup will allow you to plug in different +parsers to make tradeoffs between speed and the ability to handle bad +HTML. + +3. In Python 3 (but not Python 2), HTMLParser converts entities within +attributes to the corresponding Unicode characters. In Python 2 it's +possible to parse this string and leave the é intact. + + <a href="http://crummy.com?sacré&bleu"> + +In Python 3, the é is always converted to \xe9 during +parsing. + + += 3.0.7a = + +Added an import that makes BS work in Python 2.3. + + += 3.0.7 = + +Fixed a UnicodeDecodeError when unpickling documents that contain +non-ASCII characters. + +Fixed a TypeError that occured in some circumstances when a tag +contained no text. + +Jump through hoops to avoid the use of chardet, which can be extremely +slow in some circumstances. UTF-8 documents should never trigger the +use of chardet. + +Whitespace is preserved inside <pre> and <textarea> tags that contain +nothing but whitespace. + +Beautiful Soup can now parse a doctype that's scoped to an XML namespace. + + += 3.0.6 = + +Got rid of a very old debug line that prevented chardet from working. + +Added a Tag.decompose() method that completely disconnects a tree or a +subset of a tree, breaking it up into bite-sized pieces that are +easy for the garbage collecter to collect. + +Tag.extract() now returns the tag that was extracted. + +Tag.findNext() now does something with the keyword arguments you pass +it instead of dropping them on the floor. + +Fixed a Unicode conversion bug. + +Fixed a bug that garbled some <meta> tags when rewriting them. + + += 3.0.5 = + +Soup objects can now be pickled, and copied with copy.deepcopy. + +Tag.append now works properly on existing BS objects. (It wasn't +originally intended for outside use, but it can be now.) (Giles +Radford) + +Passing in a nonexistent encoding will no longer crash the parser on +Python 2.4 (John Nagle). + +Fixed an underlying bug in SGMLParser that thinks ASCII has 255 +characters instead of 127 (John Nagle). + +Entities are converted more consistently to Unicode characters. + +Entity references in attribute values are now converted to Unicode +characters when appropriate. Numeric entities are always converted, +because SGMLParser always converts them outside of attribute values. + +ALL_ENTITIES happens to just be the XHTML entities, so I renamed it to +XHTML_ENTITIES. + +The regular expression for bare ampersands was too loose. In some +cases ampersands were not being escaped. (Sam Ruby?) + +Non-breaking spaces and other special Unicode space characters are no +longer folded to ASCII spaces. (Robert Leftwich) + +Information inside a TEXTAREA tag is now parsed literally, not as HTML +tags. TEXTAREA now works exactly the same way as SCRIPT. (Zephyr Fang) + += 3.0.4 = + +Fixed a bug that crashed Unicode conversion in some cases. + +Fixed a bug that prevented UnicodeDammit from being used as a +general-purpose data scrubber. + +Fixed some unit test failures when running against Python 2.5. + +When considering whether to convert smart quotes, UnicodeDammit now +looks at the original encoding in a case-insensitive way. + += 3.0.3 (20060606) = + +Beautiful Soup is now usable as a way to clean up invalid XML/HTML (be +sure to pass in an appropriate value for convertEntities, or XML/HTML +entities might stick around that aren't valid in HTML/XML). The result +may not validate, but it should be good enough to not choke a +real-world XML parser. Specifically, the output of a properly +constructed soup object should always be valid as part of an XML +document, but parts may be missing if they were missing in the +original. As always, if the input is valid XML, the output will also +be valid. + += 3.0.2 (20060602) = + +Previously, Beautiful Soup correctly handled attribute values that +contained embedded quotes (sometimes by escaping), but not other kinds +of XML character. Now, it correctly handles or escapes all special XML +characters in attribute values. + +I aliased methods to the 2.x names (fetch, find, findText, etc.) for +backwards compatibility purposes. Those names are deprecated and if I +ever do a 4.0 I will remove them. I will, I tell you! + +Fixed a bug where the findAll method wasn't passing along any keyword +arguments. + +When run from the command line, Beautiful Soup now acts as an HTML +pretty-printer, not an XML pretty-printer. + += 3.0.1 (20060530) = + +Reintroduced the "fetch by CSS class" shortcut. I thought keyword +arguments would replace it, but they don't. You can't call soup('a', +class='foo') because class is a Python keyword. + +If Beautiful Soup encounters a meta tag that declares the encoding, +but a SoupStrainer tells it not to parse that tag, Beautiful Soup will +no longer try to rewrite the meta tag to mention the new +encoding. Basically, this makes SoupStrainers work in real-world +applications instead of crashing the parser. + += 3.0.0 "Who would not give all else for two p" (20060528) = + +This release is not backward-compatible with previous releases. If +you've got code written with a previous version of the library, go +ahead and keep using it, unless one of the features mentioned here +really makes your life easier. Since the library is self-contained, +you can include an old copy of the library in your old applications, +and use the new version for everything else. + +The documentation has been rewritten and greatly expanded with many +more examples. + +Beautiful Soup autodetects the encoding of a document (or uses the one +you specify), and converts it from its native encoding to +Unicode. Internally, it only deals with Unicode strings. When you +print out the document, it converts to UTF-8 (or another encoding you +specify). [Doc reference] + +It's now easy to make large-scale changes to the parse tree without +screwing up the navigation members. The methods are extract, +replaceWith, and insert. [Doc reference. See also Improving Memory +Usage with extract] + +Passing True in as an attribute value gives you tags that have any +value for that attribute. You don't have to create a regular +expression. Passing None for an attribute value gives you tags that +don't have that attribute at all. + +Tag objects now know whether or not they're self-closing. This avoids +the problem where Beautiful Soup thought that tags like <BR /> were +self-closing even in XML documents. You can customize the self-closing +tags for a parser object by passing them in as a list of +selfClosingTags: you don't have to subclass anymore. + +There's a new built-in parser, MinimalSoup, which has most of +BeautifulSoup's HTML-specific rules, but no tag nesting rules. [Doc +reference] + +You can use a SoupStrainer to tell Beautiful Soup to parse only part +of a document. This saves time and memory, often making Beautiful Soup +about as fast as a custom-built SGMLParser subclass. [Doc reference, +SoupStrainer reference] + +You can (usually) use keyword arguments instead of passing a +dictionary of attributes to a search method. That is, you can replace +soup(args={"id" : "5"}) with soup(id="5"). You can still use args if +(for instance) you need to find an attribute whose name clashes with +the name of an argument to findAll. [Doc reference: **kwargs attrs] + +The method names have changed to the better method names used in +Rubyful Soup. Instead of find methods and fetch methods, there are +only find methods. Instead of a scheme where you can't remember which +method finds one element and which one finds them all, we have find +and findAll. In general, if the method name mentions All or a plural +noun (eg. findNextSiblings), then it finds many elements +method. Otherwise, it only finds one element. [Doc reference] + +Some of the argument names have been renamed for clarity. For instance +avoidParserProblems is now parserMassage. + +Beautiful Soup no longer implements a feed method. You need to pass a +string or a filehandle into the soup constructor, not with feed after +the soup has been created. There is still a feed method, but it's the +feed method implemented by SGMLParser and calling it will bypass +Beautiful Soup and cause problems. + +The NavigableText class has been renamed to NavigableString. There is +no NavigableUnicodeString anymore, because every string inside a +Beautiful Soup parse tree is a Unicode string. + +findText and fetchText are gone. Just pass a text argument into find +or findAll. + +Null was more trouble than it was worth, so I got rid of it. Anything +that used to return Null now returns None. + +Special XML constructs like comments and CDATA now have their own +NavigableString subclasses, instead of being treated as oddly-formed +data. If you parse a document that contains CDATA and write it back +out, the CDATA will still be there. + +When you're parsing a document, you can get Beautiful Soup to convert +XML or HTML entities into the corresponding Unicode characters. [Doc +reference] + += 2.1.1 (20050918) = + +Fixed a serious performance bug in BeautifulStoneSoup which was +causing parsing to be incredibly slow. + +Corrected several entities that were previously being incorrectly +translated from Microsoft smart-quote-like characters. + +Fixed a bug that was breaking text fetch. + +Fixed a bug that crashed the parser when text chunks that look like +HTML tag names showed up within a SCRIPT tag. + +THEAD, TBODY, and TFOOT tags are now nestable within TABLE +tags. Nested tables should parse more sensibly now. + +BASE is now considered a self-closing tag. + += 2.1.0 "Game, or any other dish?" (20050504) = + +Added a wide variety of new search methods which, given a starting +point inside the tree, follow a particular navigation member (like +nextSibling) over and over again, looking for Tag and NavigableText +objects that match certain criteria. The new methods are findNext, +fetchNext, findPrevious, fetchPrevious, findNextSibling, +fetchNextSiblings, findPreviousSibling, fetchPreviousSiblings, +findParent, and fetchParents. All of these use the same basic code +used by first and fetch, so you can pass your weird ways of matching +things into these methods. + +The fetch method and its derivatives now accept a limit argument. + +You can now pass keyword arguments when calling a Tag object as though +it were a method. + +Fixed a bug that caused all hand-created tags to share a single set of +attributes. + += 2.0.3 (20050501) = + +Fixed Python 2.2 support for iterators. + +Fixed a bug that gave the wrong representation to tags within quote +tags like <script>. + +Took some code from Mark Pilgrim that treats CDATA declarations as +data instead of ignoring them. + +Beautiful Soup's setup.py will now do an install even if the unit +tests fail. It won't build a source distribution if the unit tests +fail, so I can't release a new version unless they pass. + += 2.0.2 (20050416) = + +Added the unit tests in a separate module, and packaged it with +distutils. + +Fixed a bug that sometimes caused renderContents() to return a Unicode +string even if there was no Unicode in the original string. + +Added the done() method, which closes all of the parser's open +tags. It gets called automatically when you pass in some text to the +constructor of a parser class; otherwise you must call it yourself. + +Reinstated some backwards compatibility with 1.x versions: referencing +the string member of a NavigableText object returns the NavigableText +object instead of throwing an error. + += 2.0.1 (20050412) = + +Fixed a bug that caused bad results when you tried to reference a tag +name shorter than 3 characters as a member of a Tag, eg. tag.table.td. + +Made sure all Tags have the 'hidden' attribute so that an attempt to +access tag.hidden doesn't spawn an attempt to find a tag named +'hidden'. + +Fixed a bug in the comparison operator. + += 2.0.0 "Who cares for fish?" (20050410) + +Beautiful Soup version 1 was very useful but also pretty stupid. I +originally wrote it without noticing any of the problems inherent in +trying to build a parse tree out of ambiguous HTML tags. This version +solves all of those problems to my satisfaction. It also adds many new +clever things to make up for the removal of the stupid things. + +== Parsing == + +The parser logic has been greatly improved, and the BeautifulSoup +class should much more reliably yield a parse tree that looks like +what the page author intended. For a particular class of odd edge +cases that now causes problems, there is a new class, +ICantBelieveItsBeautifulSoup. + +By default, Beautiful Soup now performs some cleanup operations on +text before parsing it. This is to avoid common problems with bad +definitions and self-closing tags that crash SGMLParser. You can +provide your own set of cleanup operations, or turn it off +altogether. The cleanup operations include fixing self-closing tags +that don't close, and replacing Microsoft smart quotes and similar +characters with their HTML entity equivalents. + +You can now get a pretty-print version of parsed HTML to get a visual +picture of how Beautiful Soup parses it, with the Tag.prettify() +method. + +== Strings and Unicode == + +There are separate NavigableText subclasses for ASCII and Unicode +strings. These classes directly subclass the corresponding base data +types. This means you can treat NavigableText objects as strings +instead of having to call methods on them to get the strings. + +str() on a Tag always returns a string, and unicode() always returns +Unicode. Previously it was inconsistent. + +== Tree traversal == + +In a first() or fetch() call, the tag name or the desired value of an +attribute can now be any of the following: + + * A string (matches that specific tag or that specific attribute value) + * A list of strings (matches any tag or attribute value in the list) + * A compiled regular expression object (matches any tag or attribute + value that matches the regular expression) + * A callable object that takes the Tag object or attribute value as a + string. It returns None/false/empty string if the given string + doesn't match, and any other value if it does. + +This is much easier to use than SQL-style wildcards (see, regular +expressions are good for something). Because of this, I took out +SQL-style wildcards. I'll put them back if someone complains, but +their removal simplifies the code a lot. + +You can use fetch() and first() to search for text in the parse tree, +not just tags. There are new alias methods fetchText() and firstText() +designed for this purpose. As with searching for tags, you can pass in +a string, a regular expression object, or a method to match your text. + +If you pass in something besides a map to the attrs argument of +fetch() or first(), Beautiful Soup will assume you want to match that +thing against the "class" attribute. When you're scraping +well-structured HTML, this makes your code a lot cleaner. + +1.x and 2.x both let you call a Tag object as a shorthand for +fetch(). For instance, foo("bar") is a shorthand for +foo.fetch("bar"). In 2.x, you can also access a specially-named member +of a Tag object as a shorthand for first(). For instance, foo.barTag +is a shorthand for foo.first("bar"). By chaining these shortcuts you +traverse a tree in very little code: for header in +soup.bodyTag.pTag.tableTag('th'): + +If an element relationship (like parent or next) doesn't apply to a +tag, it'll now show up Null instead of None. first() will also return +Null if you ask it for a nonexistent tag. Null is an object that's +just like None, except you can do whatever you want to it and it'll +give you Null instead of throwing an error. + +This lets you do tree traversals like soup.htmlTag.headTag.titleTag +without having to worry if the intermediate stages are actually +there. Previously, if there was no 'head' tag in the document, headTag +in that instance would have been None, and accessing its 'titleTag' +member would have thrown an AttributeError. Now, you can get what you +want when it exists, and get Null when it doesn't, without having to +do a lot of conditionals checking to see if every stage is None. + +There are two new relations between page elements: previousSibling and +nextSibling. They reference the previous and next element at the same +level of the parse tree. For instance, if you have HTML like this: + + <p><ul><li>Foo<br /><li>Bar</ul> + +The first 'li' tag has a previousSibling of Null and its nextSibling +is the second 'li' tag. The second 'li' tag has a nextSibling of Null +and its previousSibling is the first 'li' tag. The previousSibling of +the 'ul' tag is the first 'p' tag. The nextSibling of 'Foo' is the +'br' tag. + +I took out the ability to use fetch() to find tags that have a +specific list of contents. See, I can't even explain it well. It was +really difficult to use, I never used it, and I don't think anyone +else ever used it. To the extent anyone did, they can probably use +fetchText() instead. If it turns out someone needs it I'll think of +another solution. + +== Tree manipulation == + +You can add new attributes to a tag, and delete attributes from a +tag. In 1.x you could only change a tag's existing attributes. + +== Porting Considerations == + +There are three changes in 2.0 that break old code: + +In the post-1.2 release you could pass in a function into fetch(). The +function took a string, the tag name. In 2.0, the function takes the +actual Tag object. + +It's no longer to pass in SQL-style wildcards to fetch(). Use a +regular expression instead. + +The different parsing algorithm means the parse tree may not be shaped +like you expect. This will only actually affect you if your code uses +one of the affected parts. I haven't run into this problem yet while +porting my code. + += Between 1.2 and 2.0 = + +This is the release to get if you want Python 1.5 compatibility. + +The desired value of an attribute can now be any of the following: + + * A string + * A string with SQL-style wildcards + * A compiled RE object + * A callable that returns None/false/empty string if the given value + doesn't match, and any other value otherwise. + +This is much easier to use than SQL-style wildcards (see, regular +expressions are good for something). Because of this, I no longer +recommend you use SQL-style wildcards. They may go away in a future +release to clean up the code. + +Made Beautiful Soup handle processing instructions as text instead of +ignoring them. + +Applied patch from Richie Hindle (richie at entrian dot com) that +makes tag.string a shorthand for tag.contents[0].string when the tag +has only one string-owning child. + +Added still more nestable tags. The nestable tags thing won't work in +a lot of cases and needs to be rethought. + +Fixed an edge case where searching for "%foo" would match any string +shorter than "foo". + += 1.2 "Who for such dainties would not stoop?" (20040708) = + +Applied patch from Ben Last (ben at benlast dot com) that made +Tag.renderContents() correctly handle Unicode. + +Made BeautifulStoneSoup even dumber by making it not implicitly close +a tag when another tag of the same type is encountered; only when an +actual closing tag is encountered. This change courtesy of Fuzzy (mike +at pcblokes dot com). BeautifulSoup still works as before. + += 1.1 "Swimming in a hot tureen" = + +Added more 'nestable' tags. Changed popping semantics so that when a +nestable tag is encountered, tags are popped up to the previously +encountered nestable tag (of whatever kind). I will revert this if +enough people complain, but it should make more people's lives easier +than harder. This enhancement was suggested by Anthony Baxter (anthony +at interlink dot com dot au). + += 1.0 "So rich and green" (20040420) = + +Initial release. diff --git a/poky/bitbake/lib/bs4/__init__.py b/poky/bitbake/lib/bs4/__init__.py new file mode 100644 index 000000000..f6fdfd50b --- /dev/null +++ b/poky/bitbake/lib/bs4/__init__.py @@ -0,0 +1,468 @@ +"""Beautiful Soup +Elixir and Tonic +"The Screen-Scraper's Friend" +http://www.crummy.com/software/BeautifulSoup/ + +Beautiful Soup uses a pluggable XML or HTML parser to parse a +(possibly invalid) document into a tree representation.
