Junio C Hamano	2b86976bfd	git-prune: never lose objects reachable from our refs. Explicit <head> arguments to git-prune replaces, instead of extends, the list of heads used for reachability analysis by fsck-objects. By giving a subset of heads by mistake, objects reachable only from other heads can be removed, resulting in a corrupted repository. This commit stops replacing the list of heads, and makes the command line arguments to add to them instead for safety. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
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	41f222e87a	Be marginally more careful about removing objects The git philosophy when it comes to disk accesses is "Laugh in the face of danger". Notably, since we never modify an existing object, we don't really care that deeply about flushing things to disk, since even if the machine crashes in the middle of a git operation, you can never really have lost any old work. At most, you'd need to figure out the proper heads (which git-fsck-objects can do for you) and re-do the operation. However, there's two exceptions to this: pruning and repacking. Those operations will actually _delete_ old objects that they know about in other ways (ie that they just repacked, or that they have found in other places). However, since they actually modify old state, we should thus be a bit more careful about them. If the machine crashes and the duplicate new objects haven't been flushed to disk, you can actually be in trouble. This is trivially stupid about it by calling "sync" before removing the objects. Not very smart, but we're talking about special operations than are usually done once a week if that.

Linus Torvalds	9106c097ad	Create object subdirectories on demand (phase II) This removes the unoptimization. The previous round does not mind missing fan-out directories, but still makes sure they exist, lest older versions choke on a repository created/packed by it. This round does not play that nicely anymore -- empty fan-out directories are not created by init-db, and will stay removed by prune-packed. The prune command also removes empty fan-out directories.

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	51890a64eb	Call prune-packed from "git prune" as well. Add -n (dryrun) flag to git-prune-packed, and call it from "git prune". Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago

Linus Torvalds	b0966e1010	Make "git prune" use the "--full" flag to git-fsck-cache It's too dangerous not to. We need to follow alternate object directories etc, or we might say something is unreachable just because we didn't look it up completely.	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
Linus Torvalds	1024932f01	fsck-cache: walk the 'refs' directory if the user doesn't give any explicit references for reachability analysis. We already had that as separate logic in git-prune-script, so this is not a new special case - it's an old special case moved into fsck, making normal usage be much simpler.	20 years ago
Junio C Hamano	8ac069ac0a	Introduce GIT_DIR environment variable. During the mailing list discussion on renaming GIT_ environment variables, people felt that having one environment that lets the user (or Porcelain) specify both SHA1_FILE_DIRECTORY (now GIT_OBJECT_DIRECTORY) and GIT_INDEX_FILE for the default layout would be handy. This change introduces GIT_DIR environment variable, from which the defaults for GIT_INDEX_FILE and GIT_OBJECT_DIRECTORY are derived. When GIT_DIR is not defined, it defaults to ".git". GIT_INDEX_FILE defaults to "$GIT_DIR/index" and GIT_OBJECT_DIRECTORY defaults to "$GIT_DIR/objects". Special thanks for ideas and discussions go to Petr Baudis and Daniel Barkalow. Bugs are mine ;-) Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Junio C Hamano	d19938ab60	Rename environment variables. H. Peter Anvin mentioned that using SHA1_whatever as an environment variable name is not nice and we should instead use names starting with "GIT_" prefix to avoid conflicts. Here is what this patch does: * Renames the following environment variables: New name Old Name GIT_AUTHOR_DATE AUTHOR_DATE GIT_AUTHOR_EMAIL AUTHOR_EMAIL GIT_AUTHOR_NAME AUTHOR_NAME GIT_COMMITTER_EMAIL COMMIT_AUTHOR_EMAIL GIT_COMMITTER_NAME COMMIT_AUTHOR_NAME GIT_ALTERNATE_OBJECT_DIRECTORIES SHA1_FILE_DIRECTORIES GIT_OBJECT_DIRECTORY SHA1_FILE_DIRECTORY * Introduces a compatibility macro, gitenv(), which does an getenv() and if it fails calls gitenv_bc(), which in turn picks up the value from old name while giving a warning about using an old name. * Changes all users of the environment variable to fetch environment variable with the new name using gitenv(). * Updates the documentation and scripts shipped with Linus GIT distribution. The transition plan is as follows: * We will keep the backward compatibility list used by gitenv() for now, so the current scripts and user environments continue to work as before. The users will get warnings when they have old name but not new name in their environment to the stderr. * The Porcelain layers should start using new names. However, just in case it ends up calling old Plumbing layer implementation, they should also export old names, taking values from the corresponding new names, during the transition period. * After a transition period, we would drop the compatibility support and drop gitenv(). Revert the callers to directly call getenv() but keep using the new names. The last part is probably optional and the transition duration needs to be set to a reasonable value.

Junio C Hamano	9e30dd7c0e	Make git-prune-script executable again. I do not know why the executable bit was lost since the change went in as GIT pull, not via e-mail patch, but here is a fix. Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Linus Torvalds	4feb7a016a	Make "git-prune-script" take all refs into account. This avoids pruning the kernel v2.6.11 tree that now has a tag.	20 years ago
Junio C Hamano	ae7c0c92c0	Git-prune-script loses blobs referenced from an uncommitted cache. (updated from the version posted to GIT mailing list). When a new blob is registered with update-cache, and before the cache is written as a tree and committed, git-fsck-cache will find the blob unreachable. This patch adds a new flag, "--cache" to git-fsck-cache, with which it keeps such blobs from considered "unreachable". The git-prune-script is updated to use this new flag. At the same time it adds .git/refs// to the set of default locations to look for heads, which should be consistent with expectations from Cogito users. Without this fix, "diff-cache -p --cached" after git-prune-script has pruned the blob object will fail mysteriously and git-write-tree would also fail.

Linus Torvalds	839a7a06f3	Add the simple scripts I used to do a merge with content conflicts. They sure as hell aren't perfect, but they allow you to do: ./git-pull-script {other-git-directory} to do the initial merge, and if that had content clashes, you do merge-cache ./git-merge-one-file-script -a which tries to auto-merge. When/if the auto-merge fails, it will leave the last file in your working directory, and you can edit it and then when you're happy you can do "update-cache filename" on it. Re-do the merge-cache thing until there are no files left to be merged, and now you can write the tree and commit: write-tree commit-tree .... -p $(cat .git/HEAD) -p $(cat .git/MERGE_HEAD) and you're done.	20 years ago
