2006-10-29Only repack active packs by skipping over kept packs.Libravatar Shawn Pearce1-10/+17
During `git repack -a -d` only repack objects which are loose or which reside in an active (a non-kept) pack. This allows the user to keep large packs as-is without continuous repacking and can be very helpful on large repositories. It should also help us resolve a race condition between `git repack -a -d` and the new pack store functionality in `git-receive-pack`. Kept packs are those which have a corresponding .keep file in $GIT_OBJECT_DIRECTORY/pack. That is pack-X.pack will be kept (not repacked and not deleted) if pack-X.keep exists in the same directory when `git repack -a -d` starts. Currently this feature is not documented and there is no user interface to keep an existing pack. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-10-22Merge branch 'np/pack'Libravatar Junio C Hamano1-1/+10
* np/pack: add the capability for index-pack to read from a stream index-pack: compare only the first 20-bytes of the key. git-repack: repo.usedeltabaseoffset pack-objects: document --delta-base-offset option allow delta data reuse even if base object is a preferred base zap a debug remnant let the GIT native protocol use offsets to delta base when possible make pack data reuse compatible with both delta types make git-pack-objects able to create deltas with offset to base teach git-index-pack about deltas with offset to base teach git-unpack-objects about deltas with offset to base introduce delta objects with offset to base
2006-10-13git-repack: repo.usedeltabaseoffsetLibravatar Junio C Hamano1-1/+10
When configuration variable `repack.UseDeltaBaseOffset` is set for the repository, the command passes `--delta-base-offset` option to `git-pack-objects`; this typically results in slightly smaller packs, but the generated packs are incompatible with versions of git older than (and including) v1.4.3. We will make it default to true sometime in the future, but not for a while. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-24git-repack: allow git-repack to run in subdirectoryLibravatar Jeff King1-0/+1
Now that we explicitly create all tmpfiles below $GIT_DIR, there's no reason to care about which directory we're in. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-09-06git-repack: create new packs inside $GIT_DIR, not cwdLibravatar Martin Langhoff1-4/+7
Avoid failing when cwd is !writable by writing the packfiles in $GIT_DIR, which is more in line with other commands. Without this, git-repack was failing when run from crontab by non-root user accounts. For large repositories, this also makes the mv operation a lot cheaper, and avoids leaving temp packfiles around the fs upon failure.

2006-08-29Check if pack directory exists prior to descending into itLibravatar Matthias Kestenholz1-1/+1
This fixes the following warning: git-repack: line 42: cd: .git/objects/pack: No such file or directory This happens only, when git-repack -a is run without any packs in the repository. Signed-off-by: Matthias Kestenholz <matthias@spinlock.ch> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-12git-repack: avoid redirecting stderr into git-pack-objectsLibravatar Junio C Hamano1-1/+3
We are trying to catch error condition of git-rev-list and cause the downstream pack-objects to barf, but if you run rev-list with anything that mucks with its stderr (such as GIT_TRACE), any stderr output would cause the pipeline to fail. [jc: originally from Matthias Lederhofer, with a reworded error message.] Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-06-25git-repack: Be careful when updating the same pack as an existing one.Libravatar Junio C Hamano1-3/+18
After a clone, packfiles are read-only by default and "mv" to replace the pack with a new one goes interactive, asking if the user wants to replace it. If one is successfully moved and the other is not, the pack and its idx would become out-of-sync and corrupts the repository. Recovering is straightforward -- it is just the matter of finding the remaining .tmp-pack-* and make sure they are both moved -- but we should be extra careful not to do something so alarming to the users.

2006-06-24git-repack -- respect -q and be quietLibravatar Martin Langhoff1-2/+3

If all objects are reachable via an alternate object store then we still have to remove all obsolete local packs. Signed-off-by: Martin Waitz <tali@admingilde.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-19Allow "git repack" users to specify repacking window/depthLibravatar Linus Torvalds1-3/+5
.. but don't even bother documenting it. I don't think any normal person is supposed to ever really care, but it simplifies testing when you want to use the "git repack" wrapper rather than forcing you to use the core programs (which already do support the window/depth arguments, of course).

2006-04-02fix repacking with lots of tagsLibravatar Jim Radford1-3/+1

2005-11-25git-sh-setup: die if outside git repository.Libravatar Junio C Hamano1-1/+1
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>
2005-11-21git-repack: Properly abort in corrupt repositoryLibravatar Linus Torvalds1-1/+1
In a corrupt repository, git-repack produces a pack that does not contain needed objects without complaining, and the result of this combined with -d flag can be very painful -- e.g. a lossage of one tree object can lead to lossage of blobs reachable only through that tree.

2005-11-19git-repack: do not do complex redundancy check.Libravatar Junio C Hamano1-21/+14

This patch changes git-pack-redundant so that packfiles in alternate object directories also are considered when deciding which objects are redundant.

2005-10-28Be marginally more careful about removing objectsLibravatar Linus Torvalds1-0/+1
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. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-13Add "-l" flag for repacking only local packsLibravatar Linus Torvalds1-1/+5
This uses the new "--local" flag to git-pack-objects. It currently only makes a difference together with "-a", since a normal incremental repack won't pack any packed objects at all (whether local or remote). Eventually, it might end up skipping any objects that aren't local to the current object directory, but for now it only knows to skip packed objects.

2005-09-17Archive-destroying "git repack -a -d" bug.Libravatar Junio C Hamano1-1/+9
Using "git repack -a -d" can destroy your git archive if you use it twice in succession, because the new pack can be called the same as the old pack. Found by Linus. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-07Big tool rename.Libravatar Junio C Hamano1-0/+68
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.
