* "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.

| * Move sanitary_path_copy() to path.c and rename it to normalize_path_copy()Johannes Sixt2009-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | This function and normalize_absolute_path() do almost the same thing. The former already works on Windows, but the latter crashes. In subsequent changes we will remove normalize_absolute_path(). Here we make the replacement function reusable. On the way we rename it to reflect that it does some path normalization.

| * | Fix gitdir detection when in subdir of gitdirSZEDER Gábor2009-01-17
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the current working directory is a subdirectory of the gitdir (e.g. <repo>/.git/refs/), then setup_git_directory_gently() will climb its parent directories until it finds itself in a gitdir. However, no matter how many parent directories it climbs, it sets 'GIT_DIR_ENVIRONMENT' to ".", which is obviously wrong. This behaviour affected at least 'git rev-parse --git-dir' and hence caused some errors in bash completion (e.g. customized command prompt when on a detached head and completion of refs). To fix this, we set the absolute path of the found gitdir instead. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* make prefix_path() never return NULLDmitry Potapov2008-10-06
| | | | | | | | | | | | | | | | There are 9 places where prefix_path is called, and only in one of them the returned pointer was checked to be non-zero and only to call exit(128) as it is usually done by die(). In other 8 places, the returned value was not checked and it caused SIGSEGV when a path outside of the working tree was used. For instance, running git update-index --add /some/path/outside caused SIGSEGV. This patch changes prefix_path() to die if the path is outside of the repository, so it never returns NULL.

* setup_git_directory(): fix move to worktree toplevel directoryNguyễn Thái Ngọc Duy2008-08-30
| | | | | | | | | | | | | When setup_git_directory() returns successfully, it is supposed to move current working directory to worktree toplevel directory.

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>

* | | Make git_dir a path relative to work_tree in setup_work_tree()Linus Torvalds2008-06-19

This should save the kernel some time traversing the path to work_tree all the time if git_dir is inside work_tree. Daniel's patch didn't apply for me as-is, so I recreated it with some differences, and here are the numbers from ten runs each. There is some IO for me - probably due to more-or-less random flushing of the journal - so the variation is bigger than I'd like, but whatever: Before: real 0m8.135s real 0m7.933s real 0m8.080s real 0m7.954s real 0m7.949s real 0m8.112s real 0m7.934s real 0m8.059s real 0m7.979s real 0m8.038s After: real 0m7.685s real 0m7.968s real 0m7.703s real 0m7.850s real 0m7.995s real 0m7.817s real 0m7.963s real 0m7.955s real 0m7.848s real 0m7.969s Now, going by "best of ten" (on the assumption that the longer numbers are all due to IO), I'm saying a 7.933s -> 7.685s reduction, and it does seem to be outside of the noise (ie the "after" case never broke 8s, while the "before" case did so half the time). So looks like about 3% to me. Doing it for a slightly smaller test-case (just the "arch" subdirectory) gets more stable numbers probably due to not filling the journal with metadata updates, so we have: Before: real 0m1.633s real 0m1.633s real 0m1.633s real 0m1.632s real 0m1.632s real 0m1.630s real 0m1.634s real 0m1.631s real 0m1.632s real 0m1.632s After: real 0m1.610s real 0m1.609s real 0m1.610s real 0m1.608s real 0m1.607s real 0m1.610s real 0m1.609s real 0m1.611s real 0m1.608s real 0m1.611s where I'ld just take the averages and say 1.632 vs 1.610, which is just over 1% peformance improvement. So it's not in the noise, but it's not as big as I initially thought and measured. (That said, it obviously depends on how deep the working directory path is too, and whether it is behind NFS or something else that might need to cause more work to look up).

* get_pathspec(): die when an out-of-tree path is givenJunio C Hamano2008-03-07
| | | | | | | | | | | | | | | | | | | | | | An earlier commit d089ebaa (setup: sanitize absolute and funny paths) made get_pathspec() aware of absolute paths, but with a botched interface that forced the callers to count the resulting pathspecs in order to detect an error of giving a path that is outside the work tree. This fixes it, by dying inside the function. We had ls-tree test that relied on a misfeature in the original implementation of its pathspec handling. Leading slashes were silently removed from them. However we allow giving absolute pathnames (people want to cut and paste from elsewhere) that are inside work tree these days, so a pathspec that begin with slash _should_ be treated as a full path. The test is adjusted to match the updated rule for get_pathspec(). Earlier I mistook three tests given by Robin that they should succeed, but these are attempts to add path outside work tree, which should fail loudly. These tests also have been fixed.

* Avoid unnecessary "if-before-free" tests.Jim Meyering2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

When working inside a subdirectory, the user-supplied pathspecs are taken to be relative to the current subdirectory. Among special path components in pathspecs, we used to accept and interpret only "." ("the directory", meaning a no-op) and ".." ("up one level") at the beginning. Everything else was passed through as-is. For example, if you are in Documentation/ directory of the project, you can name Documentation/howto/maintain-git.txt as: howto/maintain-git.txt ../Documentation/howto/maitain-git.txt ../././Documentation/howto/maitain-git.txt but not as: howto/./maintain-git.txt $(pwd)/howto/maintain-git.txt This patch updates prefix_path() in several ways: - If the pathspec is not absolute, prefix (i.e. the current subdirectory relative to the root of the work tree, with terminating slash, if not empty) and the pathspec is concatenated first and used in the next step. Otherwise, that absolute pathspec is used in the next step. - Then special path components "." (no-op) and ".." (up one level) are interpreted to simplify the path. It is an error to have too many ".." to cause the intermediate result to step outside of the input to this step. - If the original pathspec was not absolute, the result from the previous step is the resulting "sanitized" pathspec. Otherwise, the result from the previous step is still absolute, and it is an error if it does not begin with the directory that corresponds to the root of the work tree. The directory is stripped away from the result and is returned. - In any case, the resulting pathspec in the array get_pathspec() returns omit the ones that caused errors. With this patch, the last two examples also behave as expected. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | Clean up work-tree handlingJohannes Schindelin2007-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old version of work-tree support was an unholy mess, barely readable, and not to the point. For example, why do you have to provide a worktree, when it is not used? As in "git status". Now it works. Another riddle was: if you can have work trees inside the git dir, why are some programs complaining that they need a work tree? IOW it is allowed to call $ git --git-dir=../ --work-tree=. bla when you really want to. In this case, you are both in the git directory and in the working tree. So, programs have to actually test for the right thing, namely if they are inside a working tree, and not if they are inside a git directory. Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was specified, unless there is a repository in the current working directory. It does now. The logic to determine if a repository is bare, or has a work tree (tertium non datur), is this: --work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true, which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR ends in /.git, which overrides the directory in which .git/ was found. In related news, a long standing bug was fixed: when in .git/bla/x.git/, which is a bare repository, git formerly assumed ../.. to be the appropriate git dir. This problem was reported by Shawn Pearce to have caused much pain, where a colleague mistakenly ran "git init" in "/" a long time ago, and bare repositories just would not work.

* | Fix core.sharedRepository = 2Johannes Schindelin2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For compatibility reasons, "git init --shared=all" does not write "all" into the config, but a number. In the shared setup, you really have to support even older clients on the _same_ repository. But git_config_perm() did not pick up on it. Also, "git update-server-info" failed to pick up on the shared permissions. This patch fixes both issues, and adds a test to prove it.

* | Do not check if getcwd() result begins with a slash.Junio C Hamano2007-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | In user space, and for getcwd(), the check to see if the resulting path begins with a '/' does not make sense. This is merely a mistake by Linus who is so used to code for the kernel, where a d_path() return value pathname can be either a real path, or something like "pipe:[8003]", and the difference is the '/' at the beginning. Pointed out by Dscho, Matthias Lederhofer and clarified by Linus. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * | introduce GIT_WORK_TREE to specify the work treeMatthias Lederhofer2007-06-06
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | setup_gdg is used as abbreviation for setup_git_directory_gently. The work tree can be specified using the environment variable GIT_WORK_TREE and the config option core.worktree (the environment variable has precendence over the config option). Additionally there is a command line option --work-tree which sets the environment variable. setup_gdg does the following now: GIT_DIR unspecified repository in .git directory parent directory of the .git directory is used as work tree, GIT_WORK_TREE is ignored GIT_DIR unspecified repository in cwd GIT_DIR is set to cwd see the cases with GIT_DIR specified what happens next and also see the note below GIT_DIR specified GIT_WORK_TREE/core.worktree unspecified cwd is used as work tree GIT_DIR specified GIT_WORK_TREE/core.worktree specified the specified work tree is used Note on the case where GIT_DIR is unspecified and repository is in cwd: GIT_WORK_TREE is used but is_inside_git_dir is always true. I did it this way because setup_gdg might be called multiple times (e.g. when doing alias expansion) and in successive calls setup_gdg should do the same thing every time. Meaning of is_bare/is_inside_work_tree/is_inside_git_dir: (1) is_bare_repository A repository is bare if core.bare is true or core.bare is unspecified and the name suggests it is bare (directory not named .git). The bare option disables a few protective checks which are useful with a working tree. Currently this changes if a repository is bare: updates of HEAD are allowed git gc packs the refs the reflog is disabled by default (2) is_inside_work_tree True if the cwd is inside the associated working tree (if there is one), false otherwise. (3) is_inside_git_dir True if the cwd is inside the git directory, false otherwise. Before this patch is_inside_git_dir was always true for bare repositories. When setup_gdg finds a repository git_config(git_default_config) is always called. This ensure that is_bare_repository makes use of core.bare and does not guess even though core.bare is specified. inside_work_tree and inside_git_dir are set if setup_gdg finds a repository. The is_inside_work_tree and is_inside_git_dir functions will die if they are called before a successful call to setup_gdg.
