* Reordering KextImageInfo::LoadImageUsingMemoryModuleJason Molenda2019-11-071-9/+15
| | | | | | | | | | | | so we only call ModulesDidLoad at the end of the method after the new module has been added to the target and the sections have all been adjusted to their actual load addresses. Solves a problem where an operating system plugin in the kernel could be loaded multiple times; the first before the binary had even been added to the target. <rdar://problem/50523558>
* remove File::SetStream(), make new files instead.Lawrence D'Anna2019-09-271-62/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch removes File::SetStream() and File::SetDescriptor(), and replaces most direct uses of File with pointers to File. Instead of calling SetStream() on a file, we make a new file and replace it. My ultimate goal here is to introduce a new API class SBFile, which has full support for python io.IOStream file objects. These can redirect read() and write() to python code, so lldb::Files will need a way to dispatch those methods. Additionally it will need some form of sharing and assigning files, as a SBFile will be passed in and assigned to the main IO streams of the debugger. In my prototype patch queue, I make File itself copyable and add a secondary class FileOps to manage the sharing and dispatch. In that case SBFile was a unique_ptr<File>. (here: https://github.com/smoofra/llvm-project/tree/files) However in review, Pavel Labath suggested that it be shared_ptr instead. (here: https://reviews.llvm.org/D67793) In order for SBFile to use shared_ptr<File>, everything else should as well. If this patch is accepted, I will make SBFile use a shared_ptr I will remove FileOps from future patches and use subclasses of File instead.

| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is a bit more explicit, and makes it possible to build LLDB without varying the -I lines per-directory. (The latter is useful because many build systems only allow this to be configured per-library, and LLDB is insufficiently layered to be split into multiple libraries on stricter build systems).

* [lldb] Also include the array definition in Properties.incJonas Devlieghere2019-07-291-5/+5
| | | | | | | | | | | | | | | | Right now our Properties.inc only generates the initializer for the options list but not the array declaration boilerplate around it. As the array definition is identical for all arrays, we might as well also let the Properties.inc generate it alongside the initializers. Unfortunately we cannot do the same for enums, as there's this magic ePropertyExperimental, which needs to come at the end to be interpreted correctly. Hopefully we can get rid of this in the future and do the same for the property enums. Differential revision: https://reviews.llvm.org/D65353 llvm-svn: 367238
* Let tablegen generate property definitionsJonas Devlieghere2019-07-253-8/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | Property definitions are currently defined in a PropertyDefinition array and have a corresponding enum to index in this array. Unfortunately this is quite error prone. Indeed, just today we found an incorrect merge where a discrepancy between the order of the enum values and their definition caused the test suite to fail spectacularly. Tablegen can streamline the process of generating the property definition table while at the same time guaranteeing that the enums stay in sync. That's exactly what this patch does. It adds a new tablegen file for the properties, building on top of the infrastructure that Raphael added recently for the command options. It also introduces two new tablegen backends: one for the property definitions and one for their corresponding enums. It might be worth mentioning that I generated most of the tablegen definitions from the existing property definitions, by adding a dump method to the struct. This seems both more efficient and less error prone that copying everything over by hand. Only Enum properties needed manual fixup for the EnumValues and DefaultEnumValue fields.

* [Logging] Replace Log::Printf with LLDB_LOG macro (NFC)Jonas Devlieghere2019-07-241-41/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces explicit calls to log::Printf with the new LLDB_LOGF macro. The macro is similar to LLDB_LOG but supports printf-style format strings, instead of formatv-style format strings. So instead of writing: if (log) log->Printf("%s\n", str); You'd write: LLDB_LOG(log, "%s\n", str); This change was done mechanically with the command below.

* C.128 override, virtual keyword handlingRaphael Isemann2019-05-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: According to [C128] "Virtual functions should specify exactly one of `virtual`, `override`, or `final`", I've added override where a virtual function is overriden but the explicit `override` keyword was missing. Whenever both `virtual` and `override` were specified, I removed `virtual`. As C.128 puts it: > [...] writing more than one of these three is both redundant and > a potential source of errors. I anticipate a discussion about whether or not to add `override` to destructors but I went for it because of an example in [ISOCPP1000]. Let me repeat the comment for you here: Consider this code: ``` struct Base { virtual ~Base(){} }; struct SubClass : Base { ~SubClass() { std::cout << "It works!\n"; } }; int main() { std::unique_ptr<Base> ptr = std::make_unique<SubClass>(); } ``` If for some odd reason somebody removes the `virtual` keyword from the `Base` struct, the code will no longer print `It works!`. So adding `override` to destructors actively protects us from accidentally breaking our code at runtime.

* Lock accesses to OptionValueFileSpecList objectsFrederic Riss2019-04-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | Before a Debugger gets a Target, target settings are routed to a global set of settings. Even without this, some part of the LLDB which exist independently of the Debugger object (the Module cache, the Symbol vendors, ...) access directly the global default store for those settings. Of course, if you modify one of those global settings while they are being read, bad things happen. We see this quite a bit with FileSpecList settings. In particular, we see many cases where one debug session changes target.exec-search-paths while another session starts up and it crashes when one of those accesses invalid FileSpecs. This patch addresses the specific FileSpecList issue by adding locking to OptionValueFileSpecList and never returning by reference.

* [NFC] Remove ASCII lines from commentsJonas Devlieghere2019-04-102-42/+0
| | | | | | | | | | | | | | | | | | | | | | | A lot of comments in LLDB are surrounded by an ASCII line to delimit the begging and end of the comment. Its use is not really consistent across the code base, sometimes the lines are longer, sometimes they are shorter and sometimes they are omitted. Furthermore, it looks kind of weird with the 80 column limit, where the comment actually extends past the line, but not by much. Furthermore, when /// is used for Doxygen comments, it looks particularly odd. And when // is used, it incorrectly gives the impression that it's actually a Doxygen comment. I assume these lines were added to improve distinguishing between comments and code. However, given that todays editors and IDEs do a great job at highlighting comments, I think it's worth to drop this for the sake of consistency. The alternative is fixing all the inconsistencies, which would create a lot more churn. Differential revision: https://reviews.llvm.org/D60508 llvm-svn: 358135
* Rename Target::GetSharedModule to Target::GetOrCreateModule.Jason Molenda2019-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a flag to control whether the ModulesDidLoad notification is called when a module is added. If the notifications are disabled, the caller must call ModulesDidLoad after adding all the new modules, but postponing this notification until they're all batched up can allow for better efficiency than notifying one-by-one. Change the name of the ModuleList notifier functions that a subclass can implement to start with 'Notify' to make it clear what they are. Add a NotifyModulesRemoved. Add header documentation for the changed/updated methods. Added defaulted-value 'notify' argument to ModuleList Append, AppendIfNeeded, and Remove because callers working with a local ModuleList don't have an obvious idea of what notify means in this context. When the ModuleList is a part of the Target class, the notify behavior matters. DynamicLoaderDarwin has been updated so that libraries being added/removed are correctly batched up before notifications are sent. Added the TestModuleLoadedNotifys.py test to run on Darwin to test this. <rdar://problem/48293064> Differential Revision: https://reviews.llvm.org/D60172 llvm-svn: 357955

Previously, lldb would read all of the kext binaries out of memory and then determine if it had the local copy. The kext table gives us most the information we need (address, name, uuid) so lldb only needs the actual in-memory load commands when it comes time to set the section load addresses. Delay reading until that point for all the kexts. NFC; doing the operations in a different order. <rdar://problem/41181173> llvm-svn: 356108

Last week I decided to try not printing any details about kexts that failed to load, only printing a summary of how many failed to load. This time I'm print different progress characters depending on whether the kext loaded or not ("-" for not), then at the end I will print a summary of how many kexts failed to load and a sorted list of the kexts with the bundle ID and the uuid. It's a lot more readable. <rdar://problem/48654569> llvm-svn: 355958

* Change the scanning algorithm in ↵Jason Molenda2019-03-062-27/+41
| | | | | | | | | | | | | | | | | | | | | | | DynamicLoaderDarwinKernel::SearchForKernelNearPC. Currently when lldb might be doing a kernel debug session, it scans through memory by taking the current pc value and looking for a kernel at megabyte boundaries, up to 32MB behind $pc. This adjusts the algorithm to scan back at every 16k page boundary and to stop scanning as soon as we hit a memory read error. The addition of stopping at a memory read error saves us from tons of unnecessary packet traffic on generic targets where lldb might look for a kernel binary. I've been trying to think of how to construct a test for this; it's a bit tricky. A gdb-remote protocol test with the contents of a fake tiny kernel mach-o binary would satisify part of it, but this kernel path also directly calls over to dsymForUUID or DebugSymbols framework lookups to find the kernel binary as well. I'll keep thinking about this one, but it's so intertangled with these two external systems that it may be hard to do. <rdar://problem/48578197> llvm-svn: 355476
* Move Host/Symbols.cpp to Symbols/LocateSymbolFile.cppZachary Turner2019-02-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Given that we have a target named Symbols, one wonders why a file named Symbols.cpp is not in this target. To be clear, the functions exposed from this file are really focused on *locating* a symbol file on a given host, which is where the ambiguity comes in. However, it makes more sense conceptually to be in the Symbols target. While some of the specific places to search for symbol files might change depending on the Host, this is not inherently true in the same way that, for example, "accessing the file system" or "starting threads" is fundamentally dependent on the Host. PDBs, for example, recently became a reality on non-Windows platforms, and it's theoretically possible that DSYMs could become a thing on non MacOSX platforms (maybe in a remote debugging scenario). Other types of symbol files, such as DWO, DWP, etc have never been tied to any Host platform anyway. After this patch, there is only one remaining dependency from Host to Target.

Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only.

* Rename ObjectFile::GetHeaderAddress to GetBaseAddressPavel Labath2018-12-111-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | Summary: This function was named such because in the case of MachO files, the mach header is located at this address. However all (most?) usages of this function were not interested in that fact, but the fact that this address is used as the base address for expressing various relative addresses in the object file. For other object file formats, this name is not appropriate (and it's probably the reason why this function was not implemented in these classes). In the ELF case the ELF header will usually end up at this address, but this is a result of the linker optimizing the file layout and not a requirement of the spec. For COFF files, I believe the is no header located at this address either.

Also, Utility, which is the only module which cannot include Host, should not be doing anything with object file formats.

* Represent invalid UUIDs as UUIDs with length zeroPavel Labath2018-06-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: During the previous attempt to generalize the UUID class, it was suggested that we represent invalid UUIDs as length zero (previously, we used an all-zero UUID for that). This meant that some valid build-ids could not be represented (it's possible however unlikely that a checksum of some file would be zero) and complicated adding support for variable length build-ids (should a 16-byte empty UUID compare equal to a 20-byte empty UUID?). This patch resolves these issues by introducing a canonical representation for an invalid UUID. The slight complication here is that some clients (MachO) actually use the all-zero notation to mean "no UUID has been set". To keep this use case working (while making it very explicit about which construction semantices are wanted), replaced the UUID constructors and the SetBytes functions with named factory methods. - "fromData" creates a UUID from the given data, and it treats all bytes equally. - "fromOptionalData" first checks the data contents - if all bytes are zero, it treats this as an invalid/empty UUID.

Created a new function ReadMachHeader and instead of reading through the target cached memory reader, start by reading only a mach header sized chunk of memory, then check it for a valid mach-o magic # and use the size of the load commands to pre-fetch the entire load commands of the kext which is the only thing we're going to read, instead of letting the generic mach-o parser read it in 512 byte chunks. Functionally this is doing exactly the same thing as before, but by cutting down on the # of packets going back and forth, even on a local connection it's close to a quarter faster than it was before. <rdar://problem/38570146> llvm-svn: 334995
* [FileSpec] Make style argument mandatory for SetFile. NFCJonas Devlieghere2018-06-131-1/+1
| | | | | | | | | | | | | | | | SetFile has an optional style argument which defaulted to the native style. This patch makes that argument mandatory so clients of the FileSpec class are forced to think about the correct syntax. At the same time this introduces a (protected) convenience method to update the file from within the FileSpec class that keeps the current style. These two changes together prevent a potential pitfall where the style might be forgotten, leading to the path being updated and the style unintentionally being changed to the host style. llvm-svn: 334663

FYI, the script I used was: import textwrap import commands import os import sys import re tmp = "%s.tmp"%sys.argv[1] out = open(tmp, "w+") with open(sys.argv[1], "r") as f: header = "" text = "" comment = re.compile(r'^( *//) ([^ ].*)$') special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$') for line in f: match = comment.match(line) if match and not special.match(match.group(2)): # skip intentionally short comments. if not text and len(match.group(2)) < 40: out.write(line) continue if text: text += " " + match.group(2) else: header = match.group(1) text = match.group(2) continue if text: filled = textwrap.wrap(text, width=(78-len(header)), break_long_words=False) for l in filled: out.write(header+" "+l+'\n') text = "" out.write(line) os.rename(tmp, sys.argv[1]) Differential Revision: https://reviews.llvm.org/D46144 llvm-svn: 331197

* We had a situation where a kext was inlined into the kernel,Jason Molenda2017-11-301-0/+10
| | | | | | | | | | | | but still listed in the kernel's kext table with the kernel binary UUID. This resulted in the kernel text section being loaded at the kext address and problems ensuing. Instead, if there is a kext with the same UUID as the kernel, lldb should skip over it. <rdar://problem/35757689> llvm-svn: 319500
* Rename Error -> Status.Zachary Turner2017-05-122-8/+8
| | | | | | | | | | | | | | | This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

| | | | | | | | | All references to Host and Core have been removed, so this class can now safely be lowered into Utility. Differential Revision: https://reviews.llvm.org/D30559 llvm-svn: 296909
