* Fix use after free in DiskFilesOrDirectoriesRaphael Isemann2018-01-221-1/+1
| | | | | | | | | | | | | | | Summary: We copy the local variable `Resolved` into `Storage` to keep it around. However, we then still let the `SearchDir` ref point to `Resolved` which then is used to access the already freed memory later on. With this patch we point to `Storage` which doesn't get deleted after the current scope exits. Discovered by memory sanitizer in the CompletionTest.DirCompletionUsername test.

* Add Utility/Environment class for handling... environmentsPavel Labath2018-01-101-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: There was some confusion in the code about how to represent process environment. Most of the code (ab)used the Args class for this purpose, but some of it used a more basic StringList class instead. In either case, the fact that the underlying abstraction did not provide primitive operations for the typical environment operations meant that even a simple operation like checking for an environment variable value was several lines of code. This patch adds a separate Environment class, which is essentialy a llvm::StringMap<std::string> in disguise. To standard StringMap functionality, it adds a couple of new functions, which are specific to the environment use case: - (most important) envp conversion for passing into execve() and likes. Instead of trying to maintain a constantly up-to-date envp view, it provides a function which creates a envp view on demand, with the expectation that this will be called as the very last thing before handing the value to the system function. - insert(StringRef KeyEqValue) - splits KeyEqValue into (key, value) pair and inserts it into the environment map. - compose(value_type KeyValue) - takes a map entry and converts in back into "KEY=VALUE" representation. With this interface most of the environment-manipulating code becomes one-liners. The only tricky part was maintaining compatibility in SBLaunchInfo, which expects that the environment entries are accessible by index and that the returned const char* is backed by the launch info object (random access into maps is hard and the map stores the entry in a deconstructed form, so we cannot just return a .c_str() value). To solve this, I have the SBLaunchInfo convert the environment into the "envp" form, and use it to answer the environment queries. Extra code is added to make sure the envp version is always in sync. (This also improves the layering situation as Args was in the Interpreter module whereas Environment is in Utility.)

* Move ArchSpec to the Utility modulePavel Labath2017-11-133-15/+1
| | | | | | | | | | | | | The rationale here is that ArchSpec is used throughout the codebase, including in places which should not depend on the rest of the code in the Core module. This commit touches many files, but most of it is just renaming of #include lines. In a couple of cases, I removed the #include ArchSpec line altogether, as the file was not using it. In one or two places, this necessitated adding other #includes like lldb-private-defines.h. llvm-svn: 318048
* Invert ArchSpec<->Platform dependencyPavel Labath2017-10-312-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: ArchSpec::SetTriple was taking a Platform as an argument, and used it to fill in missing pieces of the specified triple. I invert the dependency by moving this code to other classes. For this purpose, I've created three new functions. - HostInfo::GetAugmentedArchSpec: fills in the triple using the host platform (this used to be implemented by passing a null platform pointer). By putting this code in the Host module, we can provide a way to anyone who does not have a platform instance (lldb-server) an easy way to get Host data. - Platform::GetAugmentedArchSpec: if you have a platform instance, you can call this to let it fill in the triple. - static Platform::GetAugmentedArchSpec: implements the "if platform == 0 then use_host() else use_platform()" part.

* Support: Have directory_iterator::status() return ↵Peter Collingbourne2017-10-101-4/+4
| | | | | | | | | | | | | | | | | | FindFirstFileEx/FindNextFile results on Windows. This allows clients to avoid an unnecessary fs::status() call on each directory entry. Because the information returned by FindFirstFileEx is a subset of the information returned by a regular status() call, I needed to extract a base class from file_status that contains only that information. On my machine, this reduces the time required to enumerate a ThinLTO cache directory containing 520k files from almost 4 minutes to less than 2 seconds.

| | | | llvm-svn: 313327
* Make breakpoint names real entities.Jim Ingham2017-09-143-462/+583
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When introduced, breakpoint names were just tags that you could apply to breakpoints that would allow you to refer to a breakpoint when you couldn't capture the ID, or to refer to a collection of breakpoints. This change makes the names independent holders of breakpoint options that you can then apply to breakpoints when you add the name to the breakpoint. It adds the "breakpoint name configure" command to set up or reconfigure breakpoint names. There is also full support for then in the SB API, including a new SBBreakpointName class. The connection between the name and the breakpoints sharing the name remains live, so if you reconfigure the name, all the breakpoint options all change as well. This allows a quick way to share complex breakpoint behavior among a bunch of breakpoints, and a convenient way to iterate on the set. You can also create a name from a breakpoint, allowing a quick way to copy options from one breakpoint to another. I also added the ability to make hidden and delete/disable protected names. When applied to a breakpoint, you will only be able to list, delete or disable that breakpoint if you refer to it explicitly by ID. This feature will allow GUI's that need to use breakpoints for their own purposes to keep their breakpoints from getting accidentally disabled or deleted. <rdar://problem/22094452> llvm-svn: 313292

* Add an auto-continue flag to breakpoints & locations.Jim Ingham2017-08-031-0/+53
| | | | | | | | | | | | | | You can get a breakpoint to auto-continue by adding "continue" as a command, but that has the disadvantage that if you hit two breakpoints simultaneously, the continue will force the process to continue, and maybe even forstalling the commands on the other. The auto-continue flag means the breakpoints can negotiate about whether to stop. Writing tests, I wanted to supply some commands when I made the breakpoints, so I also added that ability. llvm-svn: 309969
* Fix a mis-feature with propagation of breakpoint options -> location options.Jim Ingham2017-08-021-31/+32
| | | | | | | | | | | | | | When an option was set at on a location, I was just copying the whole option set to the location, and letting it shadow the breakpoint options. That was wrong since it meant changes to unrelated options on the breakpoint would no longer take on this location. I added a mask of set options and use that for option propagation. I also added a "location" property to breakpoints, and added SBBreakpointLocation.{G,S}etCommandLineCommands since I wanted to use them to write some more test cases. <rdar://problem/24397798> llvm-svn: 309772

* Add debug_frame section supportPavel Labath2017-06-271-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | Summary: This is a beefed-up version of D33504, which adds support for dwarf 4 debug_frame section format. The main difference here is that the decision whether to use eh_frame or debug_frame is done on a per-function basis instead of per-object file. This is necessary because one module can contain both sections (for example, the start files added by the linker will typically pull in eh_frame), but we want to be able to access both, for maximum information. I also add unit test for parsing various CFI formats (eh_frame, debug_frame v3 and debug_frame v4).

* Introduce new command: thread backtrace uniquePavel Labath2017-06-121-14/+123
| | | | | | | | | | | | | | | | | This patch introduces a new thread backtrace command "unique". The command is based off of "thread backtrace all" but will instead find all threads which share matching call stacks and de-duplicate their output, listing call stack and all the threads which share it. This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output. I needed this behavior recently when debugging a core with 700+ threads.

* Rename Error -> Status.Zachary Turner2017-05-1225-329/+330
| | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | Previously which path syntax we supported dependend on what platform we were compiling LLVM on. While this is normally desirable, there are situations where we need to be able to handle a path that we know was generated on a remote host. Remote debugging, for example, or parsing debug info. 99% of the code in LLVM for handling paths was platform agnostic and literally just a few branches were gated behind pre-processor checks, so this changes those sites to use runtime checks instead, and adds a flag to every path API that allows one to override the host native syntax.

* Make file / directory completion work properly on Windows.Zachary Turner2017-03-121-166/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a couple of problems with this function on Windows. Different separators and differences in how tilde expressions are resolved for starters, but in addition there was no clear indication of what the function's inputs or outputs were supposed to be, and there were no tests to demonstrate its use. To more easily paper over the differences between Windows paths, non-Windows paths, and tilde expressions, I've ported this function to use LLVM-based directory iteration (in fact, I would like to eliminate all of LLDB's directory iteration code entirely since LLVM's is cleaner / more efficient (i.e. it invokes fewer stat calls)). and llvm's portable path manipulation library. Since file and directory completion assumes you are referring to files and directories on your local machine, it's safe to assume the path syntax properties of the host in doing so, so LLVM's APIs are perfect for this. I've also added a fairly robust set of unit tests. Since you can't really predict what users will be on your machine, or what their home directories will be, I added an interface called TildeExpressionResolver, and in the unit test I've mocked up a fake implementation that acts like a unix password database. This allows us to configure some fake users and home directories in the test, so we can exercise all of those hard-to-test codepaths that normally otherwise depend on the host.
