* [Support] Add sys::fs::set_current_path() (aka chdir)Pavel Labath2017-01-241-0/+12
| | | | | | | | | | | | | | | Summary: This adds a cross-platform way of setting the current working directory analogous to the existing current_path() function used for retrieving it. The function will be used in lldb. Reviewers: rafael, silvas, zturner Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D29035 llvm-svn: 292907

| | | | | | | | | | | | | | | | | | | | linker Summary: The motivation is to support better the -object_path_lto option on Darwin. The linker needs to write down the generate object files on disk for later use by lldb or dsymutil (debug info are not present in the final binary). We're moving this into libLTO so that we can be smarter when a cache is enabled and hard-link when possible instead of duplicating the files.

* Remove TimeValue usage from llvm/SupportPavel Labath2016-10-241-22/+12
| | | | | | | | | | | | | | | | | Summary: This is a follow-up to D25416. It removes all usages of TimeValue from llvm/Support library (except for the actual TimeValue declaration), and replaces them with appropriate usages of std::chrono. To facilitate this, I have added small utility functions for converting time points and durations into appropriate OS-specific types (FILETIME, struct timespec, ...).

| | | | | | GetFinalPathNameByHandle API does not behave as documented; if given a buffer that has enough space for the path but not the null terminator, the call will return the number of characters required *without* the null terminator (despite being documented otherwise) and it will not set GetLastError(). The result was that this function would return a bogus path and no error. Instead, ensure there is sufficient space for a null terminator (we already strip it off manually for compatibility with older versions of Windows). llvm-svn: 273195

* [Support] Tweak path::system_temp_directory() on Windows.Pawel Bylica2015-11-171-16/+15
| | | | | | | | | | | | | | | | | Summary: This patch changes the behavior of path::system_temp_directory() on Windows to be closer to GetTempPath Windows API call. Enforces path separator to be the native one, makes path absolute, etc. GetTempPath is not used directly because of limitations/implementation bugs on Windows 7. Windows specific unit tests are added. Most of them runs in separated process with modified environment variables. This change fixes FileSystemTest.CreateDir unittest that had been failing when run from Unix-like shell on Windows (Unix-like path separator (/) used in env variables).

* [Support] Use GetTempDir to get the temporary dir path on Windows.Pawel Bylica2015-11-061-37/+10
| | | | | | | | | | | | | | | Summary: In general GetTempDir follows the same logic as the replaced code: checks env variables TMP, TEMP, USERPROFILE in order. However, it also perform other checks like making separators native (\), making the path absolute, etc. This change fixes FileSystemTest.CreateDir unittest that had been failing when run from Unix-like shell on Windows (Unix-like path separator (/) used in env variables).

* [Support] Extend sys::path with user_cache_directory function.Pawel Bylica2015-11-021-0/+4
| | | | | | | | | | | | | | | | | | | | Summary: The new function sys::path::user_cache_directory tries to discover a directory suitable for cache storage for current system user. On Windows and Darwin it returns a path to system-specific user cache directory. On Linux it follows XDG Base Directory Specification, what is: - use non-empty $XDG_CACHE_HOME env var, - use $HOME/.cache.

* Fix rename() sometimes failing if another process uses openFileForRead()Greg Bedwell2015-10-121-10/+28
| | | | | | | | | | | | | | | | | | | On Windows, fs::rename() could fail is another process was reading the file at the same time using fs::openFileForRead(). In most cases the user wouldn't notice as fs::rename() will continue to retry for 2000ms. Typically this is enough for the read to complete and a retry to succeed, but if the disk is being it too hard then the response time might be longer than the retry time and the rename would fail with a permission error. Add FILE_SHARE_DELETE to the sharing flags for CreateFileW() in fs::openFileForRead() and try ReplaceFileW() prior to MoveFileExW() in fs::rename(). Based on an initial patch by Edd Dawson!

* ScanDirForExecutable on Windows fails to find executables with the "exe" ↵Reid Kleckner2015-09-101-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | extension in name When the driver tries to locate a program by its name, e.g. a linker, it scans the paths provided by the toolchain using the ScanDirForExecutable function. If the lookup fails, the driver uses llvm::sys::findProgramByName. Unlike llvm::sys::findProgramByName, ScanDirForExecutable is not aware of file extensions. If the program has the "exe" extension in its name, which is very common on Windows, ScanDirForExecutable won't find it under the toolchain-provided paths. This patch changes the Windows version of the "`can_execute`" function called by ScanDirForExecutable to respect file extensions, similarly to llvm::sys::findProgramByName.

* Replace windows_error calls with mapWindowsError.Yaron Keren2015-05-041-29/+25
| | | | | | | | After r210687, windows_error does nothing but call mapWindowsError. Other Windows/*.inc files directly call mapWindowsError. This patch updates Path.inc and Process.inc to do the same. llvm-svn: 236409
* [FS] Report errors from llvm::sys::fs::rename on WindowsReid Kleckner2015-04-101-0/+1
| | | | | | | | | | Previously we would always report success, which is pretty bogus. I'm too lazy to write a test where rename will portably fail on all platforms. I'm just trying to fix breakage introduced by r234597, which happened to tickle this. llvm-svn: 234611
* Remove many superfluous SmallString::str() calls.Yaron Keren2015-03-181-2/+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

* Improve long path name support on Windows.Paul Robinson2014-11-131-38/+66
| | | | | | | | | | Windows normally limits the length of an absolute path name to 260 characters; directories can have lower limits. These limits increase to about 32K if you use absolute paths with the special '\\?\' prefix. Teach Support\Windows\Path.inc to use that prefix as needed. TODO: Other parts of Support could also learn to use this prefix. llvm-svn: 221841
* Misc cleanups to the FileSytem api.Rafael Espindola2014-09-111-33/+13
| | | | | | | | | | | | | | | | The main difference is the removal of std::error_code exists(const Twine &path, bool &result); It was an horribly redundant interface since a file not existing is also a valid error_code. Now we have an access function that returns just an error_code. This is the only function that has to be implemented for Unix and Windows. The functions can_write, exists and can_execute an now just wrappers. One still has to be very careful using these function to avoid introducing race conditions (Time of check to time of use). llvm-svn: 217625
* Add writeFileWithSystemEncoding to LibLLVMSuppor.Rafael Espindola2014-09-031-4/+16
| | | | | | | | | | | | | | | | | | | | This patch adds to LLVMSupport the capability of writing files with international characters encoded in the current system encoding. This is relevant for Windows, where we can either use UTF16 or the current code page (the legacy Windows international characters). On UNIX, the file is always saved in UTF8. This will be used in a patch for clang to thoroughly support response files creation when calling other tools, addressing PR15171. On Windows, to correctly support internationalization, we need the ability to write response files both in UTF16 or the current code page, depending on the tool we will call. GCC for mingw, for instance, requires files to be encoded in the current code page. MSVC tools requires files to be encoded in UTF16. Patch by Rafael Auler! llvm-svn: 217068
* Merge TempDir and system_temp_directory.Rafael Espindola2014-08-261-17/+45
| | | | | | | | | We had two functions for finding the temp or cache directory. Each had a different set of smarts about OS specific APIs. With this patch system_temp_directory becomes the only way to do it. llvm-svn: 216460
