* [VFS] Let the user decide if they want path normalization.Benjamin Kramer2015-10-121-2/+31
| | | | | | | | | | | | | | 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.

* [VFS] Don't try to be heroic with '.' in paths.Benjamin Kramer2015-10-121-5/+3
| | | | | | | 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
* [VFS] remove handling of '..' for now.Benjamin Kramer2015-10-121-3/+0
| | | | | | | | | 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
* [VFS] Just normalize away .. and . in paths for in-memory file systems.Benjamin Kramer2015-10-091-0/+3
| | | | | | This simplifies the code and gets us support for .. for free. llvm-svn: 249830

* [VFS] Transition clang-format to use an in-memory FS.Benjamin Kramer2015-10-061-0/+12
| | | | | | | | | | | 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
* Fix the MSVC build.Rafael Espindola2015-10-051-4/+4
| | | | | | No idea what asymmetry MSVC is findind. llvm-svn: 249346
* [VFS] Add working directories to every virtual file system.Benjamin Kramer2015-10-051-0/+6
| | | | | | | | | | | | 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
* [VFS] Add an in-memory file system implementation.Benjamin Kramer2015-10-051-0/+67
| | | | | | | | | | 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
* [VFS] Remove setName from the file interface.Benjamin Kramer2015-10-051-6/+6
| | | | | | | This streamlines the interface a bit and makes Status more immutable. No functional change intended. llvm-svn: 249310

* Make VFS and FileManager match the current MemoryBuffer API.Benjamin Kramer2014-10-261-8/+2
| | | | | | | This eliminates converting back and forth between the 3 formats and gives us a more homogeneous interface. llvm-svn: 220657

| | | | | | | | | 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

| | | | | | | | | | | 1) missing iterator bits needed by libstdc++4.7 Using find_if was convenient, but since operator++ wasn't a good interface anyway, I just replaced with a range-based for loop and removed operator++ from the directory_iterator class. 2) stop relying on order of iterating real files llvm-svn: 211633
* Disable the bits of r211623 that broke the botsBen Langmuir2014-06-241-15/+16
| | | | | | | Part of my test seems to rely on iterator bits that I didn't implement, at least in the gcc bots. Disabling while I investigate. llvm-svn: 211625
* Add directory_iterator for (non-recursive) iteration of VFS directoriesBen Langmuir2014-06-241-0/+242
| | | | | | | | 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

* Add a 'use-external-names' option to VFS overlay filesBen Langmuir2014-02-271-2/+52
| | | | | | | | | | | | | | | | When true, sets the name of the file to be the name from 'external-contents'. Otherwise, you get the virtual path that the file was looked up by. This will not affect any non-virtual paths, or fully virtual paths (for which there is no reasonable 'external' name anyway). The setting is available globally, but can be overriden on a per-file basis. The goal is that this setting will control which path you see in debug info, diagnostics, etc. which are sensitive to which path is used. That will come in future patches that pass the name through to FileManager. llvm-svn: 202329
* Allow multi-component paths in VFS file nodesBen Langmuir2014-02-251-0/+61
| | | | | | | | | | | | | | | | This allows the 'name' field to contain a path, like { 'type': 'directory', 'name': '/path/to/dir', 'contents': [ ... ] } which not only simplifies reading and writing these files (for humans), but makes it possible to easily modify locations via textual replacement, which would not have worked in the old scheme. E.g. sed s:<ROOT>:<NEW ROOT> llvm-svn: 202109
* Improve some gtest assertionsBen Langmuir2014-02-241-26/+26

* Pass through context for DiagHandler in VFSBen Langmuir2014-02-241-27/+31
| | | | | | | This allows the unit tests to not use global state when checking diagnostics. llvm-svn: 202072
* Add a VFSFromYAML class and a parser to create itBen Langmuir2014-02-211-15/+263
| | | | | | | | | | | | | | | Provides a way to create a virtual file system using a YAML file that supports mapping a file to a path on an 'external' file system. The external file system will typically be the 'real' file system, but for testing it can be changed. A future patch will add a clang option to allow the user to specify such a file and overlay it, but for now this code is only exercised by the unit tests.

* Recommit virtual file systemBen Langmuir2014-02-201-0/+216
| | | | | | | | | | | Previously reverted in r201755 due to causing an assertion failure. I've removed the offending assertion, and taught the CompilerInstance to create a default virtual file system inside createFileManager. In the future, we should be able to reach into the CompilerInvocation to customize this behaviour without breaking clients that don't care. llvm-svn: 201818
