symlinks: remove PATH_MAX limitation

2014-07-07T18:22:42Z

'git checkout' fails if a directory is longer than PATH_MAX, because the lstat_cache in symlinks.c checks if the leading directory exists using PATH_MAX-bounded string operations. Remove the limitation by using strbuf instead. Signed-off-by: Karsten Blees Signed-off-by: Junio C Hamano

symlinks.c: mark private file-scope symbols as static

Add threaded versions of functions in symlinks.c.

2012-03-03T07:56:28Z

check_leading_path() and has_dirs_only_path() both always use the default cache, which could be a caveat for adding parallelism (which is a concern and even a GSoC proposal). Reimplement these two in terms of new threaded_check_leading_path() and threaded_has_dirs_only_path() that take their own copy of the cache. Signed-off-by: Jared Hance Signed-off-by: Junio C Hamano

do not overwrite untracked symlinks

2011-02-22T06:51:07Z

Git traditionally overwrites untracked symlinks silently. This will generally not cause massive data loss, but it is inconsistent with the behavior for regular files, which are not silently overwritten. With this change, git refuses to overwrite untracked symlinks by default. If the user really wants to overwrite the untracked symlink, he has git-clean and git-checkout -f at his disposal.

do not overwrite files in leading path

2010-10-13T21:34:09Z

If the work tree contains an untracked file x, and unpack-trees wants to checkout a path x/*, the file x is removed unconditionally. Instead, apply the same checks that are normally used for untracked files, and abort if the file cannot be removed. Signed-off-by: Clemens Buchacher

lstat_cache: optionally return match_len

2010-10-13T21:34:08Z

Return match_len so that the caller can know which leading path component matched. Signed-off-by: Clemens Buchacher

symlinks.c: remove unused functions

2010-01-18T06:49:36Z

invalidate_lstat_cache() and clear_lstat_cache() are not used anywhere. Signed-off-by: Junio C Hamano

lstat_cache: guard against full match of length of 'name' parameter

2009-07-30T03:20:12Z

longest_path_match() in symlinks.c does exactly what it's name says, but in some cases that match can be too long, since the has_*_leading_path() functions assumes that the match will newer be as long as the name string given to the function. fix this by adding an extra if test which checks if the match length is equal to the 'len' parameter. Signed-off-by: Junio C Hamano

Export thread-safe version of 'has_symlink_leading_path()'

2009-07-10T03:05:19Z

The threaded index preloading will want it, so that it can avoid locking by simply using a per-thread symlink/directory cache. Signed-off-by: Linus Torvalds Signed-off-by: Junio C Hamano

Prepare symlink caching for thread-safety

2009-07-10T03:05:19Z

This doesn't actually change the external interfaces, so they are still thread-unsafe, but it makes the code internally pass a pointer to a local 'struct cache_def' around, so that the core code can be made thread-safe. The threaded index preloading will want to verify that the paths leading up to a pathname are all real directories. Signed-off-by: Linus Torvalds Signed-off-by: Junio C Hamano
