Fredrik Kuivinen	d025524d9d	Usage message clean-up, take #2 There were some problems with the usage message clean-up patch series. I hadn't realised that subdirectory aware scripts can't source git-sh-setup. I propose that we change this and let the scripts which are subdirectory aware set a variable, SUBDIRECTORY_OK, before they source git-sh-setup. The scripts will also set USAGE and possibly LONG_USAGE before they source git-sh-setup. If LONG_USAGE isn't set it defaults to USAGE. If we go this way it's easy to catch --help in git-sh-setup, print the (long) usage message to stdout and exit cleanly. git-sh-setup can define a 'usage' shell function which can be called by the scripts to print the short usage string to stderr and exit non-cleanly. It will also be easy to change $0 to basename $0 or something else, if would like to do that sometime in the future. What follows is a patch to convert a couple of the commands to this style. If it's ok with everyone to do it this way I will convert the rest of the scripts too. [jc: thrown in to proposed updates queue for comments.] Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	2a1ddc58e4	git-sh-setup: move the repository check to a core program. Any core commands that use setup_git_directory() now check if given GIT_DIR is really a valid repository, so the same check in git-sh-setup can use it without reimplementing it in shell. This commit changes git-sh-setup to use git-var command for that, although any other commands would do. Note that we export GIT_DIR explicitly when calling git-var; without it, the caller of this script would use GIT_DIR that we return (which is to assume ./.git unless the caller has it elsewhere) while git-var would go up to find a .git directory in our parent directories, which would be checking a different directory from what our callers will be using.

Junio C Hamano	ae2b0f1518	git-sh-setup: die if outside git repository. Now all the users of this script detect its exit status and die, complaining that it is outside git repository. So move the code that dies from all callers to git-sh-setup script. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	230f13225d	Create object subdirectories on demand This makes it possible to have a "sparse" git object subdirectory structure, something that has become much more attractive now that people use pack-files all the time. As a result of pack-files, a git object directory doesn't necessarily have any individual objects lying around, and in that case it's just wasting space to keep the empty first-level object directories around: on many filesystems the 256 empty directories will be aboue 1MB of diskspace. Even more importantly, after you re-pack a project that _used_ to be unpacked, you could be left with huge directories that no longer contain anything, but that waste space and take time to look through. With this change, "git prune-packed" can just do an rmdir() on the directories, and they'll get removed if empty, and re-created on demand. This patch also tries to fix up "write_sha1_from_fd()" to use the new common infrastructure for creating the object files, closing a hole where we might otherwise leave half-written objects in the object database. [jc: I unoptimized the part that really removes the fan-out directories to ease transition. init-db still wastes 1MB of diskspace to hold 256 empty fan-outs, and prune-packed rmdir()'s the grown but empty directories, but runs mkdir() immediately after that -- reducing the saving from 150KB to 146KB. These parts will be re-introduced when everybody has the on-demand capability.] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	8098a178b2	Add git-symbolic-ref 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.

Junio C Hamano	e2f5f6ef67	Do not require clean tree when reverting and cherry-picking. My stupidity deserved to be yelled at by Linus ... there is no reason to require the working tree to be clean when merging -- the only requirements are index to match HEAD commit and the paths involved in merge are up to date in the working tree. Revert and cherry-pick are just specialized forms of merge, and the requirements should be the same. Remove the 'general purpose routine to make sure tree is clean' from git-sh-setup, to prevent me from getting tempted again. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	365527adbf	Fix CDPATH problem. CDPATH has two problems: * It takes scripts to unexpected places (somebody had CDPATH=..:../..:$HOME and the "cd" in git-clone.sh:get_repo_base took him to $HOME/.git when he said "clone foo bar" to clone a repository in "foo" which had "foo/.git"). CDPATH mechanism does not implicitly give "." at the beginning of CDPATH, which is the most irritating part. * The extra echo when it does its thing confuses scripts further. Most of our scripts that use "cd" includes git-sh-setup so the problem is primarily fixed there. git-clone starts without a repository, and it needs its own fix.

Junio C Hamano	215a7ad1ef	Big tool rename. As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more. The commands installed do not have any such suffix so users do not have to remember if something is implemented as a shell script or not. (2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.

Junio C Hamano	48313592bf	Redo "revert" using three-way merge machinery. The reverse patch application using "git apply" sometimes is too rigid. Since the user would get used to resolving conflicting merges by hand during the normal merge experience, using the same machinery would be more helpful rather than just giving up. Cherry-picking and reverting are essentially the same operation. You pick one commit, and apply the difference that commit introduces to its own commit ancestry chain to the current tree. Revert applies the diff in reverse while cherry-pick applies it forward. They share the same logic, just different messages and merge direction. Rewrite "git rebase" using "git cherry-pick".

Linus Torvalds	5f5608bcec	[PATCH] Make .git directory validation code test HEAD 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).

Linus Torvalds	e4ad5f0979	[PATCH] Make git-sh-setup-script do what it was supposed to do Duh. A missing && meant that half the tests that git-sh-setup-script were _meant_ to do were actually totally ignored. In particular, the git sanity checking ended up only testing that the GIT_OBJECT_DIRECTORY was sane, not that GIT_DIR itself was..

Linus Torvalds	51cb06c36d	Add "git-push-script" to make a more regular interface It only does local and ssh pushes, because it's really just a wrapper for git-send-pack. We might make it do an rsync mirror or something, of course.	20 years ago
Linus Torvalds	b33e966608	Add "git-sh-setup-script" for common git shell script setup It sets up the normal git environment variables and a few helper functions (currently just "die()"), and returns ok if it all looks like a git archive. So use it something like . git-sh-setup-script \|\| die "Not a git archive" to make the rest of the git scripts more careful and readable.	20 years ago
