2008-07-13Make usage strings dash-lessLibravatar Stephan Beyer1-1/+1
When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version. For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh generates a dash-less usage string now.

2008-05-14Provide git_config with a callback-data parameterLibravatar Johannes Schindelin1-3/+3
git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

2008-05-11builtin-gc.c: deprecate --prune, it now really has no effectLibravatar Brandon Casey1-2/+1
2008-05-11git-gc: always use -A when manually repackingLibravatar Brandon Casey1-11/+2
Now that repack -A will leave unreferenced objects unpacked, there is no reason to use the -a option to repack (which will discard unreferenced objects). The unpacked unreferenced objects will not be repacked by a subsequent repack, and will eventually be pruned by git-gc based on the gc.pruneExpire config option.

Recent discussion on the list, with the improvement f7c22cc (always start looking up objects in the last used pack first, 2007-05-30) brought in, reached the concensus that the current default 20 is too low.

2008-03-19builtin-gc.c: allow disabling all auto-gc'ing by assigning 0 to gc.autoLibravatar Brandon Casey1-3/+3
The gc.auto configuration variable is somewhat ambiguous now that there is also a gc.autopacklimit setting. Some users may assume that it controls all auto-gc'ing. Also, now users must set two configuration variables to zero when they want to disable autopacking. Since it is unlikely that users will want to autopack based on some threshold of pack files when they have disabled autopacking based on the number of loose objects, be nice and allow a setting of zero for gc.auto to disable all autopacking.

2008-03-12gc: call "prune --expire 2.weeks.ago" by defaultLibravatar Johannes Schindelin1-2/+15
The only reason we did not call "prune" in git-gc was that it is an inherently dangerous operation: if there is a commit going on, you will prune loose objects that were just created, and are, in fact, needed by the commit object just about to be created. Since it is dangerous, we told users so. That led to many users not even daring to run it when it was actually safe. Besides, they are users, and should not have to remember such details as when to call git-gc with --prune, or to call git-prune directly. Of course, the consequence was that "git gc --auto" gets triggered much more often than we would like, since unreferenced loose objects (such as left-overs from a rebase or a reset --hard) were never pruned. Alas, git-prune recently learnt the option --expire <minimum-age>, which makes it a much safer operation. This allows us to call prune from git-gc, with a grace period of 2 weeks for the unreferenced loose objects (this value was determined in a discussion on the git list as a safe one). If you want to override this grace period, just set the config variable gc.pruneExpire to a different value; an example would be [gc] pruneExpire = 6.months.ago or even "never", if you feel really paranoid. Note that this new behaviour makes "--prune" be a no-op. While adding a test to t5304-prune.sh (since it really tests the implicit call to "prune"), also the original test for "prune --expire" was moved there from t1410-reflog.sh, where it did not belong.

Brandon Casey correctly points out that we repack with -A without --prune and with -a with --prune, so it is not just unreferenced loose objects that are pruned away when the option is given. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-10-15git-gc: by default use safer "-A" option to repack when not --prune'ingLibravatar Brandon Casey1-1/+11
This makes use of repack's new "-A" option which does not drop packed unreachable objects. This makes git-gc safe to call at any time, particularly when a repository is referenced as an alternate by another repository. git-gc --prune will use the "-a" option to repack instead of "-A", so that packed unreachable objects will be removed.

2007-09-17git-gc --auto: run "repack -A -d -l" as necessary.Libravatar Junio C Hamano1-6/+54
This teaches "git-gc --auto" to consolidate many packs into one without losing unreachable objects in them by using "repack -A" when there are too many packfiles that are not marked with *.keep in the repository. gc.autopacklimit configuration can be used to set the maximum number of packs a repository is allowed to have before this mechanism kicks in.

2007-09-17git-gc --auto: restructure the way "repack" command line is built.Libravatar Junio C Hamano1-5/+10

2007-09-17git-gc --auto: protect ourselves from accumulated cruftLibravatar Junio C Hamano1-8/+17
Deciding to run "repack -d -l" when there are too many loose objects would backfire when there are too many loose objects that are unreachable, because repacking that way would never improve the situation. Detect that case by checking the number of loose objects again after automatic garbage collection runs, and issue an warning to run "prune" manually. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-09-06Implement git gc --autoLibravatar Junio C Hamano1-1/+63
This implements a new option "git gc --auto". When gc.auto is set to a positive value, and the object database has accumulated roughly that many number of loose objects, this runs a lightweight version of "git gc". The primary difference from the full "git gc" is that it does not pass "-a" option to "git repack", which means we do not try to repack _everything_, but only repack incrementally. We still do "git prune-packed". The default threshold is arbitrarily set by yours truly to: - not trigger it for fully unpacked git v0.99 history; - do trigger it for fully unpacked git v1.0.0 history; - not trigger it for incremental update to git v1.0.0 starting from fully packed git v0.99 history. This patch does not add invocation of the "auto repacking". It is left to key Porcelain commands that could produce tons of loose objects to add a call to "git gc --auto" after they are done their work. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-05-24Make "git gc" pack all refs by defaultLibravatar Linus Torvalds1-2/+2
I've taught myself to use "git gc" instead of doing the repack explicitly, but it doesn't actually do what I think it should do. We've had packed refs for a long time now, and I think it just makes sense to pack normal branches too. So I end up having to do git pack-refs --all --prune in order to get a nice git repo that doesn't have any unnecessary files. So why not just do that in "git gc"? It's not as if there really is any downside to packing branches, even if they end up changing later. Quite often they don't, and even if they do, so what? Also, make the default for refs packing just be an unambiguous "do it", rather than "do it by default only for non-bare repositories". If you want that behaviour, you can always just add a [gc] packrefs = notbare in your ~/.gitconfig file, but I don't actually see why bare would be any different (except for the broken reason that http-fetching used to be totally broken, and not doing it just meant that it didn't even get fixed in a timely manner!). So here's a trivial patch to make "git gc" do a better job. Hmm? Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-05-10Add --aggressive option to 'git gc'Libravatar Theodore Tso1-2/+30
This option causes 'git gc' to more aggressively optimize the repository at the cost of taking much more wall clock and CPU time. Today this option causes git-pack-objects to use --no-use-delta option, and it allows the --window parameter to be set via the gc.aggressiveWindow configuration parameter.
