Jeff Hostetler 7e9b21aa 2015-02-27T08:54:48 Fix p_ftruncate to handle big files for git_clone
Edward Thomson 527ed59a 2015-02-13T09:18:49 win32: limit the mode to `_wopen`/`_waccess` Win32 generally ignores Unix-like mode bits that don't make any sense on the platform (eg `0644` makes no sense to Windows). But WINE complains loudly when presented with POSIXy bits. Remove them. (Thanks @phkelley)
Edward Thomson 3c68bfcd 2015-02-04T18:24:31 stat: don't remove trailing '/' from root on win32 `p_stat` calls `git_win32_path_from_utf8`, which canonicalizes the path. Do not further try to modify the path, else we trim the trailing slash from a root directory and try to access `C:` instead of `C:/`.
Edward Thomson cceae9a2 2014-12-01T13:09:58 win32: use NT-prefixed "\\?\" paths When turning UTF-8 paths into UCS-2 paths for Windows, always use the \\?\-prefixed paths. Because this bypasses the system's path canonicalization, handle the canonicalization functions ourselves. We must: 1. always use a backslash as a directory separator 2. only use a single backslash between directories 3. not rely on the system to translate "." and ".." in paths 4. remove trailing backslashes, except at the drive root (C:\)
Edward Thomson 8d45b469 2014-10-11T14:34:24 p_lstat win32: don't canonicalize volume mounts A reparse point that is an IO_REPARSE_TAG_MOUNT_POINT could be a junction or an actual filesystem mount point. (Who knew?) If it's the latter, its reparse point will report the actual volume information \??\Volume{GUID}\ and we should not attempt to dereference that further, instead readlink should report EINVAL since it's not a symlink / junction and its original path was canonical. Yes, really.

Carlos Martín Nieto e58281aa 2014-04-04T14:40:38 filebuf: make unlocking atomic When renaming a lock file to its final location, we need to make sure that it is replaced atomically. We currently have a workaround for Windows by removing the target file. This means that the target file, which may be a ref or a packfile, may cease to exist for a short wile, which shold be avoided. Implement the workaround only in Windows, by making sure that the file we want to replace is writable.
Carlos Martín Nieto 0731a5b4 2014-05-14T19:12:48 indexer: mmap fixes for Windows Windows has its own ftruncate() called _chsize_s(). p_mkstemp() is changed to use p_open() so we can make sure we open for writing; the addition of exclusive create is a good thing to do regardless, as we want a temporary path for ourselves. Lastly, MSVC doesn't quite know how to add two numbers if one of them is a void pointer, so let's alias it to unsigned char.C

Philip Kelley c2c81615 2014-04-19T18:05:31 Win32: UTF-8 <-> WCHAR conversion overhaul
Jan Melcher 2873a862 2014-03-27T12:42:44 Retry renaming files on Access Denied errors When a file is open for reading (without shared-delete permission), and then a different thread/process called p_rename, that would fail, even if the file was only open for reading for a few milliseconds. This change lets p_rename wait up to 50ms for the file to be closed by the reader. Applies only to win32. This is especially important for git_filebuf_commit, because writes should not fail if the file is read simultaneously. Fixes #2207
Russell Belfer 14997dc5 2013-10-08T12:45:43 More filemode cleanups for FAT on MacOS This cleans up some additional issues. The main change is that on a filesystem that doesn't support mode bits, libgit2 will now create new blobs with GIT_FILEMODE_BLOB always instead of being at the mercy to the filesystem driver to report executable or not. This means that if "core.filemode" lies and claims that filemode is not supported, then we will ignore the executable bit from the filesystem. Previously we would have allowed it. This adds an option to the new git_repository_reset_filesystem to recurse through submodules if desired. There may be other types of APIs that would like a "recurse submodules" option, but this one is particularly useful. This also has a number of cleanups, etc., for related things including trying to give better error messages when problems come up from the filesystem. For example, the FAT filesystem driver on MacOS appears to return errno EINVAL if you attempt to write a filename with invalid UTF-8 in it. We try to capture that with a better error message now.
Edward Thomson 238b7614 2013-08-16T13:31:24 Fix p_inet_pton on windows p_inet_pton on Windows should set errno properly for callers. Rewrite p_inet_pton to handle error cases correctly and add test cases to exercise this function.
Edward Thomson 86967cc5 2013-08-19T16:44:17 Use time(2) to get the time We didn't use the added precision in gettimeofday, so remove it. This prevents us from having an unnecessary reimplementation on win32.
Martin Woodward c9340df0 2013-08-16T19:40:58 Give credit to PHP for the p_readlink function in posix_w32.c
Russell Belfer ee065601 2013-08-13T09:53:56 Minor win32 fixes and improvements This is just a bunch of small fixes that I noticed while looking at the UTF8 and UTF16 path stuff. It fixes a slowdown in looking for an empty directory (not exiting loop asap), makes the dir name in the git__DIR structure be a GIT_FLEX_ARRAY to save an allocation, and fixes some slightly odd assumptions in the cl_getenv helper.

Russell Belfer cccacac5 2012-11-14T22:41:51 Add POSIX compat lstat() variant for win32 The existing p_lstat implementation on win32 is not quite POSIX compliant when setting errno to ENOTDIR. This adds an option to make is be compliant so that code (such as checkout) that cares to have separate behavior for ENOTDIR can use it portably. This also contains a couple of other minor cleanups in the posix_w32.c implementations to avoid unnecessary work.

Russell Belfer 44ef8b1b 2012-04-13T13:00:10 Fix warnings on 64-bit windows builds This fixes all the warnings on win64 except those in deps, which come from the regex code.
Russell Belfer deafee7b 2012-03-14T17:36:15 Continue error conversion This converts blob.c, fileops.c, and all of the win32 files. Also, various minor cleanups throughout the code. Plus, in testing the win32 build, I cleaned up a bunch (although not all) of the warnings with the 64-bit build.
Russell Belfer e1de726c 2012-03-12T22:55:40 Migrate ODB files to new error handling This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to the new style of error handling. Also got the unix and win32 versions of map.c. There are some minor changes to other files but no others were completely converted. This also contains an update to filebuf so that a zeroed out filebuf will not think that the fd (== 0) is actually open (and inadvertently call close() on fd 0 if cleaned up). Lastly, this was built and tested on win32 and contains a bunch of fixes for the win32 build which was pretty broken.
Vicent Martí cb8a7961 2012-03-07T00:02:55 error-handling: Repository This also includes droping `git_buf_lasterror` because it makes no sense in the new system. Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.
Vicent Martí 60bc2d20 2012-02-14T21:23:11 error-handling: Add new routines Obviously all the old throw routines are still in place, so we can gradually port over.

nulltoken 489c3666 2011-12-14T20:00:34 posix_w32: prevent segfaulting on Windows when building a temporary filename
Russell Belfer 97769280 2011-11-30T11:27:15 Use git_buf for path storage instead of stack-based buffers This converts virtually all of the places that allocate GIT_PATH_MAX buffers on the stack for manipulating paths to use git_buf objects instead. The patch is pretty careful not to touch the public API for libgit2, so there are a few places that still use GIT_PATH_MAX. This extends and changes some details of the git_buf implementation to add a couple of extra functions and to make error handling easier. This includes serious alterations to all the path.c functions, and several of the fileops.c ones, too. Also, there are a number of new functions that parallel existing ones except that use a git_buf instead of a stack-based buffer (such as git_config_find_global_r that exists alongsize git_config_find_global). This also modifies the win32 version of p_realpath to allocate whatever buffer size is needed to accommodate the realpath instead of hardcoding a GIT_PATH_MAX limit, but that change needs to be tested still.

Vicent Marti 11d51ca6 2011-10-26T16:43:55 windows: Add support for non-UTF codepages Our previous assumption that all paths in Windows are encoded in UTF-8 is rather weak, specially when considering that Git is encoding-agnostic. These set of functions allow the user to change the library's active codepage globally, so it is possible to access paths and files on all international versions of Windows. Note that the default encoding here is UTF-8 because we assume that 99% of all Git repositories will be in UTF-8. Also, if you use non-ascii characters in paths, anywhere, please burn on a fire.
