* prefix_filename(): safely handle the case where pfx_len=0Thomas Rast2010-10-18
| | | | | | | | | | | | Current prefix_filename() is proofed against the case where the prefix 'pfx' is NULL or a 0-length string, _except on Windows_. Change the behaviour to work the same on both platforms, and only check pfx_len so that callers passing a NULL prefix with a nonzero pfx_len segfault early on both.

If they were to search for a repository sooner, then the outcome of such early repository accesses would be more predictable and reliable. The cmd_*() functions learn whether a repository was found through the *nongit_ok return value from setup_git_directory_gently(). If run_builtin() is to take care of the repository search itself, that datum needs to be retrievable from somewhere else. Use the startup_info struct for this. As a bonus, this information becomes available to functions such as git_config() which might want to avoid trying to access a repository when none is present.

This way, the effect of running a git command from a subdir of .git will be the same whether or not GIT_DIR is explicitly set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original declaration was int, which seems to cause trouble on my machine. It causes spurious "filesystem boundary" errors when running the testsuite. The cause seems to be $ stat -c%d . 2147549952 which is too large for a 32-bit int type. Using the correct type, dev_t, solves the issue. (Because I'm paranoid and forgetful, I checked -- yes, Unix v7 had dev_t.) Other uses of st_dev seem to be reasonably safe. fill_stat_cache_info truncates it to an 'unsigned int', but that value seems to be used only to validate the cache, and only if USE_STDEV is defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regarding the new environment variable, Linus Torvalds <torvalds@linux-foundation.org> writes on Tue, 30 Mar 2010 in <alpine.LFD.2.00.1003301537150.3707@i5.linux-foundation.org>: I suspect that it is _very_ unusual to have a source repo that crosses multiple filesystems, and the original reason for this patch-series seems to me to be likely to be more common than that multi-fs case. So having the logic go the other way would seem to match the common case, no? The "crossing filesystem boundary" condition is checked by comparing st_dev field in the result from stat(2). This is slightly worrysome if non-POSIX ports return different values in the field even for directories in the same work tree extracted to the same "filesystem". Erik Faye-Lund confirms that in the msysgit port st_dev is 0, so this should be safe, as "even Windows is safe" ;-) This will affect those who use /.git to cram /etc and /home/me in the same repostiory, /home is mounted from non-root filesystem, and a git operation is done from inside /home/me/src. But that is such a corner case we don't want to give preference over helping people who will benefit from having this default so that they do not have to suffer from slow automounters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Git should work regardless where the working directory is located, even at root. This patch fixes two places where it assumes working directory always have parent directory. In setup_git_directory_gently(), when Git goes up to root and finds .git there, it happily sets worktree to "" instead of "/". In prefix_path(), loosen the outside repo check a little bit. Usually when a path XXX is inside worktree /foo, it must be either "/foo", or "/foo/...". When worktree is simply "/", we can safely ignore the check: we have a slash at the beginning already. Not related to worktree, but also set gitdir correctly if a bare repo is placed (insanely?) at root. Thanks João Carlos Mendes Luís for pointing out this problem.

It leaves the setenv(GIT_DIR_ENVIRONMENT, ...) calls in git.c alone, as they respond to command line switches that emulate the effect of setting the environment variable directly. The remaining site in environment.c is in set_git_dir() and is left alone, too, of course.

* "core.sharedrepository = 0mode" should set, not loosenJunio C Hamano2009-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the behaviour of octal notation to how it is defined in the documentation, while keeping the traditional "loosen only" semantics intact for "group" and "everybody". Three main points of this patch are: - For an explicit octal notation, the internal shared_repository variable is set to a negative value, so that we can tell "group" (which is to "OR" in 0660) and 0660 (which is to "SET" to 0660); - git-init did not set shared_repository variable early enough to affect the initial creation of many files, notably copied templates and the configuration. We set it very early when a command-line option specifies a custom value. - Many codepaths create files inside $GIT_DIR by various ways that all involve mkstemp(), and then call move_temp_to_file() to rename it to its final destination. We can add adjust_shared_perm() call here; for the traditional "loosen-only", this would be a no-op for many codepaths because the mode is already loose enough, but with the new behaviour it makes a difference.

Rather we make sure that only "normalized" paths enter the depths of the machinery. We have to translate backslashes to forward slashes in the prefix and in command line arguments. Fortunately, all of them are passed through functions in setup.c. A macro has_dos_drive_path() is defined that checks whether a path begins with a drive letter+colon combination. This predicate is always false on Unix. Another macro is_dir_sep() abstracts that a backslash is also a directory separator on Windows. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>
