* Subject: setup: officially support --work-tree without --git-dirJonathan Nieder2011-01-21
| | | | | | | | | | | | | | | | | | | | The original intention of --work-tree was to allow people to work in a subdirectory of their working tree that does not have an embedded .git directory. Because their working tree, which their $cwd was in, did not have an embedded .git, they needed to use $GIT_DIR to specify where it is, and because this meant there was no way to discover where the root level of the working tree was, so we needed to add $GIT_WORK_TREE to tell git where it was. However, this facility has long been (mis)used by people's scripts to start git from a working tree _with_ an embedded .git directory, let git find .git directory, and then pretend as if an unrelated directory were the associated working tree of the .git directory found by the discovery process. It happens to work in simple cases, and is not worth causing "regression" to these scripts. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * setup_work_tree: adjust relative $GIT_WORK_TREE after moving cwdNguyễn Thái Ngọc Duy2010-12-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When setup_work_tree() is called, it moves cwd to $GIT_WORK_TREE and makes internal copy of $GIT_WORK_TREE absolute. The environt variable, if set by user, remains unchanged. If the variable is relative, it is no longer correct because its base dir has changed. Instead of making $GIT_WORK_TREE absolute too, we just say "." and let subsequent git processes handle it.

| * setup: rework setup_explicit_git_dir()Nguyễn Thái Ngọc Duy2010-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function is the most complex one among the three setup_* functions because all GIT_DIR, GIT_WORK_TREE, core.worktree and core.bare are involved. Because core.worktree is only effective inside setup_explicit_git_dir() and the extra code in setup_git_directory() is to handle that. The extra code can now be retired. Also note that setup_explicit assignment is removed, worktree setting is no longer decided by get_git_work_tree(). get_git_work_tree() will be simplified in the next commit.

| * setup: limit get_git_work_tree()'s to explicit setup case onlyNguyễn Thái Ngọc Duy2010-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_git_work_tree() takes input as core.worktree, core.bare, GIT_WORK_TREE and decides correct worktree setting. Unfortunately it does not do its job well. core.worktree and GIT_WORK_TREE should only be taken into account, if GIT_DIR is set (which is handled by setup_explicit_git_dir). For other setup cases, only core.bare matters. Add a temporary variable setup_explicit to adjust get_git_work_tree() behavior as such. This variable will be gone once setup_* rework is done. Also remove is_bare_repository_cfg check in set_git_work_tree() to ease the rework. We are going to check for core.bare and core.worktree early before setting worktree. For example, if core.bare is true, no need to set worktree. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * Use git_config_early() instead of git_config() during repo setupNguyễn Thái Ngọc Duy2010-12-22
| | | | | | | | | | | | | | | | | | | | | | | | When git_config() is called, either git_dir has already been set (by $GIT_DIR env or set_git_dir()), or it will default git_dir to ".git". git_config_early() gives setup functions more freedom because it does not require git_dir. Give it a config path, it will happily examine it. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The value cannot vary from thread to thread anyway, since the cwd is global. So now in your builtin command, instead of passing prefix around, when you want to convert a user-supplied path to a cwd-relative path, you can use startup_info->prefix directly. Caveat: As with the return value from setup_git_directory_gently(), startup_info->prefix would be NULL when the original cwd is not a subdir of the toplevel. Longer term, this would allow the prefix to be reused when several noncooperating functions require access to the same repository (for example, when accessing configuration before running a builtin).

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.

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.

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.

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.

* Use die_errno() instead of die() when checking syscallsThomas Rast2009-06-27
| | | | | | | | | | | | | | | | | | | | Lots of die() calls did not actually report the kind of error, which can leave the user confused as to the real problem. Use die_errno() where we check a system/library call that sets errno on failure, or one of the following that wrap such calls: Function Passes on error from -------- -------------------- odb_pack_keep open read_ancestry fopen read_in_full xread strbuf_read xread strbuf_read_file open or strbuf_read_file strbuf_readlink readlink write_in_full xwrite Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Convert existing die(..., strerror(errno)) to die_errno()Thomas Rast2009-06-27
| | | | | | | | | | | Change calls to die(..., strerror(errno)) to use the new die_errno(). In the process, also make slight style adjustments: at least state _something_ about the function that failed (instead of just printing the pathname), and put paths in single quotes.

* "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.

* Merge branch 'js/maint-1.6.0-path-normalize'Junio C Hamano2009-02-10
|\ | | | | | | | | | | | | | | | | * js/maint-1.6.0-path-normalize: Remove unused normalize_absolute_path() Test and fix normalize_path_copy() Fix GIT_CEILING_DIRECTORIES on Windows Move sanitary_path_copy() to path.c and rename it to normalize_path_copy() Make test-path-utils more robust against incorrect use
| * 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. Apart from that this is only moving around code. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
