* standardize and improve lookup rules for external local reposjk/git-dir-lookupJeff King2012-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you specify a local repository on the command line of clone, ls-remote, upload-pack, receive-pack, or upload-archive, or in a request to git-daemon, we perform a little bit of lookup magic, doing things like looking in working trees for .git directories and appending ".git" for bare repos. For clone, this magic happens in get_repo_path. For everything else, it happens in enter_repo. In both cases, there are some ambiguous or confusing cases that aren't handled well, and there is one case that is not handled the same by both methods. This patch tries to provide (and test!) standard, sensible lookup rules for both code paths. The intended changes are: 1. When looking up "foo", we have always preferred a working tree "foo" (containing "foo/.git" over the bare "foo.git". But we did not prefer a bare "foo" over "foo.git". With this patch, we do so. 2. We would select directories that existed but didn't actually look like git repositories. With this patch, we make sure a selected directory looks like a git repo. Not only is this more sensible in general, but it will help anybody who is negatively affected by change (1) negatively (e.g., if they had "foo.git" next to its separate work tree "foo", and expect to keep finding "foo.git" when they reference "foo"). 3. The enter_repo code path would, given "foo", look for "foo.git/.git" (i.e., do the ".git" append magic even for a repo with working tree). The clone code path did not; with this patch, they now behave the same. In the unlikely case of a working tree overlaying a bare repo (i.e., a ".git" directory _inside_ a bare repo), we continue to treat it as a working tree (prefering the "inner" .git over the bare repo). This is mainly because the combination seems nonsensical, and I'd rather stick with existing behavior on the off chance that somebody is relying on it.

Make the callers handle this case instead. As we are always returning a fresh copy of a string (or NULL), change the type of the returned value to non-const "char *".

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to do partial commits, git-commit overlays a tree on the cache and checks pathspecs against the result. Currently, the overlaying is done using "prefix" which prevents relative pathspecs with ".." and absolute pathspec from matching when they refer to files not under "prefix" and absent from the index, but still in the tree (i.e. files staged for removal). The point of providing a prefix at all is performance optimization. If we say there is no common prefix for the files of interest, then we have to read the entire tree into the index. But even if we cannot use the working directory as a prefix, we can still figure out if there is a common prefix for all given paths, and use that instead. The pathspec_prefix() routine from ls-files.c does exactly that. Any use of global variables is removed from pathspec_prefix() so that it can be called from commit.c.

Rename misguided "gently" parameter, which is turned off _only_ when the "detailed diagnosis" codepath knows that it cannot be a ref and making the call only for the caller to die with a message. Flip its meaning (and adjust the callers) and call it "only_to_die", which is not a great name, but it describes far more clearly what the codepaths that switches their behaviour based on this variable do.

The former would have applied the '*' magic to the pattern "Makefile", while the latter would used no magic to the pattern "*Makefile". Instead, just reserve all non-alnum ASCII letters that are neither glob nor regexp special as potential magic signature, and when we see a magic that is not supported, die with an error message, just like the longhand codepath does. With this, ":%#!*Makefile" will always mean "%#!" magic applied to the pattern "*Makefile", no matter what version of git is used (it is a different matter if the version of git supports all of these three magic matching rules). Also make ':' without anything else to mean "there is no pathspec". This would allow differences between "git log" and "git log ." run from the top level of the working tree (the latter simplifies no-op commits away from the history) to be expressed from a subdirectory by saying "git log :".

For example, you should be able to say: $ edit Makefile ;# top-level $ cd Documentation $ edit git.txt ;# in the subdirectory and then do one of three things, still inside the subdirectory: $ git add -u . ;# add only Documentation/git.txt $ git add -u :/ ;# add everything, including paths outside Documentation $ git add -u ;# whatever the default setting is. To truly support magic pathspec, the API needs to be restructured so that get_pathspec() and init_pathspec() are unified into one call. Currently, the former just prefixes the user supplied pathspec with the current subdirectory path, and the latter takes the output from the former and pre-parses them into a bit richer structure for easier handling. They should become a single API function that takes the current subdirectory path and the remainder of argv[] (after parsing --options and revision arguments from the command line) and returns an array of parsed pathspec elements, and "magic" should become attributes of struct pathspec_item. This patch implements only "top" magic because it can be hacked into the system without such a refactoring. The syntax for magic pathspec prefix is designed to be extensible yet simple to type to invoke a simple magic like "from the top". The parser for the magic prefix is hooked into get_pathspec() function in this patch, and it needs to be moved when we refactor the API. But we have to start from somewhere.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | setup: save prefix (original cwd relative to toplevel) in startup_infoNguyễn Thái Ngọc Duy2010-12-071-1/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Save the path from the original cwd to the cwd at the end of the setup procedure in the startup_info struct introduced in e37c1329 (2010-08-05). 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).

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v1.6.1.3~4^2 (Fix gitdir detection when in subdir of gitdir, 2009-01-16) did not go far enough: when a git directory is an ancestor of the original working directory, not only should GIT_DIR be set to point to the .git directory, but the original working directory should be restored before carrying out the relevant command. 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. Noticed while investigating v1.6.0.3~1 (rehabilitate 'git index-pack' inside the object store, 2008-10-20).
