* Move deny_non_fast_forwards handling completely into receive-pack.Shawn Pearce2006-10-30
| | | | | | | | | | | The 'receive.denynonfastforwards' option has nothing to do with the repository format version. Since receive-pack already uses git_config to initialize itself before executing any updates we can use the normal configuration strategy and isolate the receive specific variables away from the core variables.

* add receive.denyNonFastforwards config variableJohannes Schindelin2006-09-20
| | | | | | | | | | | | If receive.denyNonFastforwards is set to true, git-receive-pack will deny non fast-forwards, i.e. forced updates. Most notably, a push to a repository which has that flag set will fail. As a first user, 'git-init-db --shared' sets this flag, since in a shared setup, you are most unlikely to want forced pushes to succeed.

* Fix crash when GIT_DIR is invalidJohannes Schindelin2006-08-04

* setup_git_directory_gently: do not barf when GIT_DIR is given.Matthias Lederhofer2006-07-30
| | | | | | | | | Earlier we barfed when GIT_DIR environment variable points at a directory yet to be created, which made it impossible to use configuration mechanism in "git-init-db". Signed-off-by: Matthias Lederhofer <matled@gmx.net> Signed-off-by: Junio C Hamano <junkio@cox.net>
* shared repository: optionally allow reading to "others".Junio C Hamano2006-06-10
| | | | | | | | | | | | | | | | | | | | | | This enhances core.sharedrepository to have additionally specify that read and exec permissions to be given to others as well. It is useful when serving a repository via gitweb and git-daemon that runs as a user outside the project group. The configuration item can take the following values: [core] sharedrepository ; the same as "group" sharedrepository = true ; ditto sharedrepository = 1 ; ditto sharedrepository = group ; allow rwx to group sharedrepository = all ; allow rwx to group, allow rx to other sharedrepository = umask ; not shared - use umask It also extends "git init-db" to take "--shared=all" and friends from the command line.

* revision parsing: make "rev -- paths" checks stronger.Junio C Hamano2006-04-26
| | | | | | | | | | | | | | | | | If you don't have a "--" marker, then: - all of the arguments we are going to assume are pathspecs must exist in the working tree. - none of the arguments we parsed as revisions could be interpreted as a filename. so that there really isn't any possibility of confusion in case somebody does have a revision that looks like a pathname too. The former rule has been in effect; this implements the latter. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Fix filename verification when in a subdirectoryLinus Torvalds2006-04-26
| | | | | | | | | | | | | | | | | When we are in a subdirectory of a git archive, we need to take the prefix of that subdirectory into accoung when we verify filename arguments. Noted by Matthias Lederhofer This also uses the improved error reporting for all the other git commands that use the revision parsing interfaces, not just git-rev-parse. Also, it makes the error reporting for mixed filenames and argument flags clearer (you cannot put flags after the start of the pathname list).

* Introduce core.sharedrepositoryJohannes Schindelin2005-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the config variable 'core.sharedrepository' is set, the directories $GIT_DIR/objects/ $GIT_DIR/objects/?? $GIT_DIR/objects/pack $GIT_DIR/refs $GIT_DIR/refs/heads $GIT_DIR/refs/heads/tags are set group writable (and g+s, since the git group may be not the primary group of all users). Since all files are written as lock files first, and then moved to their destination, they do not have to be group writable. Indeed, if this leads to problems you found a bug. Note that -- as in my first attempt -- the config variable is set in the function which checks the repository format. If this were done in git_default_config instead, a lot of programs would need to be modified to call git_config(git_default_config) first.

| * working from subdirectory: preparationJunio C Hamano2005-11-28
| | | | | | | | | | | | | | | | | | | | | | - prefix_filename() is like prefix_path() but can be used to name any file on the filesystem, not the files that might go into the index file. - setup_git_directory_gently() tries to find the GIT_DIR, but does not die() if called outside a git repository.

* setup_git_directory: make sure GIT_DIR is a valid repository.Junio C Hamano2005-11-25
| | | | | | | | | | | setup_git_directory() always trusted what the user told where GIT_DIR was, and assumed that is a valid .git/ directory. This commit changes it to at least do the same level validation as is_toplevel_directory() does -- has refs/, has objects/ unless GIT_OBJECT_DIRECTORY is set, and has valid HEAD symlink or symref.

* Add git-symbolic-refJunio C Hamano2005-10-01
| | | | | | | | | | | | | This adds the counterpart of git-update-ref that lets you read and create "symbolic refs". By default it uses a symbolic link to represent ".git/HEAD -> refs/heads/master", but it can be compiled to use the textfile symbolic ref. The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah .git/HEAD' have been converted to use new git-symbolic-ref command, so that they can deal with either implementation.

* [PATCH] Make .git directory validation code test HEADLinus Torvalds2005-08-27
| | | | | | | | | | | | | | | | | | | | | | | Inspired by a report by Kalle Valo, this changes git-sh-setup-script and the "setup_git_directory()" function to test that $GIT_DIR/HEAD is a symlink, since a number of core git features depend on that these days. We used to allow a regular file there, but git-fsck-cache has been complaining about that for a while, and anything that uses branches depends on the HEAD file being a symlink, so let's just encode that as a fundamental requirement. Before, a non-symlink HEAD file would appear to work, but have subtle bugs like not having the HEAD show up as a valid reference (because it wasn't under "refs"). Now, we will complain loudly, and the user can fix it up trivially instead of getting strange behaviour. This also removes the tests for "$GIT_DIR" and "$GIT_OBJECT_DIRECTORY" being directories, since the other tests will implicitly test for that anyway (ie the tests for HEAD, refs and 00 would fail).

* [PATCH] Export relative path handling "prefix_path()" functionLinus Torvalds2005-08-17
| | | | | | | | | Not all programs necessarily have a pathspec array of pathnames, some of them (like git-update-cache) want to do things one file at a time. So export the single-path interface too. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* [PATCH] Improve handling of "." and ".." in git-diff-*Linus Torvalds2005-08-16
| | | | | | | | | | | | | This fixes up usage of ".." (without an ending slash) and "." (with or without the ending slash) in the git diff family. It also fixes pathspec matching for the case of an empty pathspec, since a "." in the top-level directory (or enough ".." under subdirectories) will result in an empty pathspec. We used to not match it against anything, but it should in fact match everything. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* [PATCH] Fix test failure due to overly strict .git directory testsLinus Torvalds2005-08-16
| | | | | | | | We may not actually have a valid HEAD at all times, so relax the validity tests for a .git subdirectory accordingly. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* [PATCH] Make "git diff" work inside relative subdirectoriesLinus Torvalds2005-08-16
We always show the diff as an absolute path, but pathnames to diff are taken relative to the current working directory (and if no pathnames are given, the default ends up being all of the current working directory). Note that "../xyz" also works, so you can do cd linux/drivers/char git diff ../block and it will generate a diff of the linux/drivers/block changes.
