2015-10-12[VFS] Let the user decide if they want path normalization.Benjamin Kramer1-16/+30
This is a more principled version of what I did earlier. Path normalization is generally a good thing, but may break users in strange environments, e. g. using lots of symlinks. Let the user choose and default it to on. This also changes adding a duplicated file into returning an error if the file contents are different instead of an assertion failure. Differential Revision: http://reviews.llvm.org/D13658 llvm-svn: 250060
2015-10-12[VFS] Don't try to be heroic with '.' in paths.Benjamin Kramer1-8/+11
Actually the only special path we have to handle is ./foo, the rest is tricky to get right so do the same thing as the existing YAML vfs here. llvm-svn: 250036
2015-10-12[VFS] remove handling of '..' for now.Benjamin Kramer1-2/+2
This can fail badly if we're overlaying a real file system and there are symlinks there. Just keep the path as-is for now. This essentially reverts r249830. llvm-svn: 250021
2015-10-09[VFS] Rename RedirectingFS internals to avoid collisions with public clang ↵Benjamin Kramer1-24/+29
classes Hopefully fixes the MSVC build. NFC intended. llvm-svn: 249832
2015-10-09[VFS] Just normalize away .. and . in paths for in-memory file systems.Benjamin Kramer1-17/+10
This simplifies the code and gets us support for .. for free. llvm-svn: 249830
2015-10-07[VFS] Port driver tool chains to VFS.Benjamin Kramer1-0/+5
There are still some loose ends here but it's sufficient so we can detect GCC headers that are inside of a VFS. llvm-svn: 249556
2015-10-07[VFS] Refactor VFSFromYAML a bit.Benjamin Kramer1-60/+57
- Rename it to RedirectingFileSystem. This is what it does, YAML is just a serialization format for it. - Consistently use unique_ptr for memory management. No functional change intended. llvm-svn: 249532
2015-10-07[VFS] Also drop '.' when adding files to an in-memory FS.Benjamin Kramer1-0/+7
Otherwise we won't be able to find them later. llvm-svn: 249525
2015-10-06[VFS] Put the incoming name in the file status to make InMemoryFS behave ↵Benjamin Kramer1-1/+1
more like a real FS. llvm-svn: 249409
2015-10-06[VFS] Transition clang-format to use an in-memory FS.Benjamin Kramer1-0/+16
Apart from being cleaner this also means that clang-format no longer has access to the host file system. This isn't necessary because clang-format never reads includes :) Includes minor tweaks and bugfixes found in the VFS implementation while running clang-format tests. llvm-svn: 249385
2015-10-05Remove duplicated default arguments. NFC.Benjamin Kramer1-10/+8
llvm-svn: 249355
2015-10-05[VFS] Fix the windows build by including the right headers.Benjamin Kramer1-0/+8

2015-10-05[VFS] Fix compilation on systems where time_t is not int64_t.Benjamin Kramer1-4/+4
No functional change intended. llvm-svn: 249318
2015-10-05[VFS] Add working directories to every virtual file system.Benjamin Kramer1-8/+65
For RealFileSystem this is getcwd()/chdir(), the synthetic file systems can make up one for themselves. OverlayFileSystem now synchronizes the working directories when a new FS is added to the overlay or the overlay working directory is set. This allows purely artificial file systems that have zero ties to the underlying disks. Differential Revision: http://reviews.llvm.org/D13430 llvm-svn: 249316
2015-10-05[VFS] Add an in-memory file system implementation.Benjamin Kramer1-0/+246
This is a simple file system tree of memory buffers that can be filled by a client. In conjunction with an OverlayFS it can be used to make virtual files accessible right next to physical files. This can be used as a replacement for the virtual file handling in FileManager and which I intend to remove eventually. llvm-svn: 249315
2015-10-05[VFS] Move class out of method so it looks less like Java.Benjamin Kramer1-26/+28
No functionality change. llvm-svn: 249314
2015-10-05[VFS] Remove setName from the file interface.Benjamin Kramer1-36/+62
This streamlines the interface a bit and makes Status more immutable. No functional change intended. llvm-svn: 249310
2015-06-24Remove a limited and somewhat questionable DenseMapInfo specializationChandler Carruth1-14/+0
for StringRef now that the core DenseMap library provides this facility. llvm-svn: 240530

llvm-svn: 240353
2015-06-22Fixed/added namespace ending comments using clang-tidy. NFCAlexander Kornienko1-2/+2
The patch is generated using this command: $ tools/extra/clang-tidy/tool/run-clang-tidy.py -fix \ -checks=-*,llvm-namespace-comment -header-filter='llvm/.*|clang/.*' \ work/llvm/tools/clang To reduce churn, not touching namespaces spanning less than 10 lines. llvm-svn: 240270
2015-04-11Use 'override/final' instead of 'virtual' for overridden methodsAlexander Kornienko1-3/+3
Summary: The patch is generated using clang-tidy misc-use-override check. This command was used: tools/clang/tools/extra/clang-tidy/tool/run-clang-tidy.py \ -checks='-*,misc-use-override' -header-filter='llvm|clang' -j=32 -fix Reviewers: dblaikie Reviewed By: dblaikie Subscribers: klimek, cfe-commits Differential Revision: http://reviews.llvm.org/D8926 llvm-svn: 234678
2015-03-18Remove many superfluous SmallString::str() calls.Yaron Keren1-2/+2
Now that SmallString is a first-class citizen, most SmallString::str() calls are not required. This patch removes a whole bunch of them, yet there are lots more. There are two use cases where str() is really needed: 1) To use one of StringRef member functions which is not available in SmallString. 2) To convert to std::string, as StringRef implicitly converts while SmallString do not. We may wish to change this, but it may introduce ambiguity. llvm-svn: 232622
2015-01-14[cleanup] Re-sort *all* #include lines with llvm/utils/sort_includes.pyChandler Carruth1-1/+1
Sorry for the noise, I managed to miss a bunch of recent regressions of include orderings here. This should actually sort all the includes for Clang. Again, no functionality changed, this is just a mechanical cleanup that I try to run periodically to keep the #include lines as regular as possible across the project. llvm-svn: 225979
2014-11-19Update for LLVM API changeDavid Blaikie1-1/+1
llvm-svn: 222303
2014-10-26Make VFS and FileManager match the current MemoryBuffer API.Benjamin Kramer1-49/+34
This eliminates converting back and forth between the 3 formats and gives us a more homogeneous interface. llvm-svn: 220657

2014-07-15VirtualFileSystem: Correctly generate the mapping for an empty VFSJustin Bogner1-23/+22
In r209332 I accidentally broke generation of empty VFS maps. This fixes the issue and adds a test. llvm-svn: 213028
2014-07-06Update for llvm api change.Rafael Espindola1-3/+8
llvm-svn: 212408
2014-06-25Add vfs::recursive_directory_iteratorBen Langmuir1-0/+35
For now, this is only used by its unit tests. It is similar to the API in llvm::sys::fs::recursive_directory_iterator, but without some of the more complex features like requesting that the iterator not recurse into the next directory, for example. llvm-svn: 211732
2014-06-24Add directory_iterator for (non-recursive) iteration of VFS directoriesBen Langmuir1-7/+191
The API is based on sys::fs::directory_iterator, but it allows iterating over overlays and the yaml-based VFS. For now, it isn't used by anything (except its tests). llvm-svn: 211623

2014-06-11Use std::error_code instead of llvm::error_code.Rafael Espindola1-12/+12
This is an update for a llvm api change. llvm-svn: 210688
2014-05-31Use make_error_code in preparation for making errc an enum class.Rafael Espindola1-8/+8
llvm-svn: 209956
2014-05-31Use error_code() instead of error_code::succes()Rafael Espindola1-3/+3
There is no std::error_code::success, so this removes much of the noise in transitioning to std::error_code. llvm-svn: 209949
2014-05-23Stopgap fix for finding module for a file mapped in the VFSBen Langmuir1-2/+4
If we lookup a path using its 'real' path first, we need to ensure that when we run header search we still use the VFS-mapped path or we will not be able to find the corresponding module for the header. The real problem is that we tie the name of a file to its underlying FileEntry, which is uniqued by inode, so we only ever get the first name it is looked up by. This doesn't work with modules, which rely on a specific file system structure. I'm hoping to have time to write up a proposal for fixing this more permanently soon, but as a stopgap this patch updates the name of the file's directory if it comes from a VFS mapping. llvm-svn: 209534
2014-05-21VirtualFileSystem: Fix a few directory traversal bugs in VFSWriterJustin Bogner1-81/+92
There are a couple of issues with writing VFS maps that are awkward to fix within the current mutually recursive approach. Instead, replace the algorithm with an iterative version that uses an explicit stack of directories. Includes tests for cases the old approach was tripping on. llvm-svn: 209332
2014-05-20VirtualFileSystem: Fix false positives in YAMLVFSWriter::containedInJustin Bogner1-1/+10
Checking if a path starts with another path isn't sufficient for determining if one is contained within the heirarchy of the other. We need to ensure that the substring ends at a directory boundary. llvm-svn: 209250
2014-05-20VirtualFileSystem: Add YAMLVFSWriter to generate VFS mapping filesJustin Bogner1-0/+116
This moves the logic to write a JSON VFS mapping from the C api into VirtualFileSystem, so that we can use it internally. No functional change. llvm-svn: 209241
