Karsten Blees	d34e70d6b8	fix deletion of .git/objects sub-directories in git-prune/repack Both git-prune and git-repack (and thus, git-gc) try to rmdir while holding a DIR* handle on the directory. This can leave dangling empty directories in the .git/objects on platforms where directory cannot be removed while they are open. First call closedir() and then rmdir(); that is more logical ordering.

Linus Torvalds	81b50f3ce4	Move 'builtin-' into a 'builtin/' subdirectory This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago

Alex Riesen	691f1a28bf	replace direct calls to unlink(2) with unlink_or_warn This helps to notice when something's going wrong, especially on systems which lock open files. I used the following criteria when selecting the code for replacement: - it was already printing a warning for the unlink failures - it is in a function which already printing something or is called from such a function - it is in a static function, returning void and the function is only called from a builtin main function (cmd_) - it is in a function which handles emergency exit (signal handlers) - it is in a function which is obvously cleaning up the lockfiles Signed-off-by: Alex Riesen <raa.lkml@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Johannes Sixt	531e6daa03	prune-packed: advanced progress even for non-existing fan-out directories A progress indicator is used to count through the 256 object fan-out directories while unused object files are removed. (However, it becomes visible only if this process takes long enough.) Previously, display_progress() was only called if object files were actually removed. But if directories towards the end (fd/, fe/, ff/) did not exist, this could leave a strange line Removing duplicate objects: 99% (255/256), done. in the terminal instead of the expected "100% (256/256)".

Junio C Hamano	cd673c1f17	has_sha1_pack(): refactor "pretend these packs do not exist" interface Most of the callers of this function except only one pass NULL to its last parameter, ignore_packed. Introduce has_sha1_kept_pack() function that has the function signature and the semantics of this function, and convert the sole caller that does not pass NULL to call this new function. All other callers and has_sha1_pack() lose the ignore_packed parameter. Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Stephan Beyer	1b1dd23f2d	Make usage strings dash-less 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.

Nicolas Pitre	4d4fcc5451	relax usage of the progress API Since it is now OK to pass a null pointer to display_progress() and stop_progress() resulting in a no-op, then we can simplify the code and remove a bunch of lines by not making those calls conditional all the time.

Shawn O. Pearce	b5d72f0a4c	Teach prune-packed to use the standard progress meter Rather than reimplementing the progress meter logic and always showing 100 lines of output while pruning already packed objects we now use a delayed progress meter and only show it if there are enough objects to make us take a little while. Most users won't see the message anymore as it usually doesn't take very long to delete the already packed loose objects. This neatens the output of a git-gc or git-repack execution, which is especially important for a `git gc --auto` triggered from within another command. We perform the display_progress() call from within the very innermost loop in case we spend more than 1 second within any single object directory. This ensures that a progress_update event from the timer will still trigger in a timely fashion and allow the user to see the progress meter. While I'm in here I changed the message to be more descriptive of its actual task. "Removing unused objects" is a little scary for new users as they wonder where these unused objects came from and how they should avoid them. Truth is these objects aren't unused in the sense of what git-prune would call a dangling object, these are used but are just duplicates of things we have already stored in a packfile.

Junio C Hamano	b60daf0515	Make git-prune-packed a bit more chatty. Steven Grimm noticed that git-repack's verbosity is inconsistent because pack-objects is chatty and prune-packed is not.

J. Bruce Fields	2eb53e65bd	Make prune also run prune-packed Both the git-prune manpage and everday.txt say that git-prune should also prune unpacked objects that are also found in packs, by running git prune-packed.

Junio C Hamano	106d710bc1	pack-objects --unpacked=<existing pack> option. Incremental repack without -a essentially boils down to: rev-list --objects --unpacked --all \| pack-objects $new_pack which picks up all loose objects that are still live and creates a new pack. This implements --unpacked=<existing pack> option to tell the revision walking machinery to pretend as if objects in such a pack are unpacked for the purpose of object listing. With this, we could say: rev-list --objects --unpacked=$active_pack --all \| pack-objects $new_pack instead, to mean "all live loose objects but pretend as if objects that are in this pack are also unpacked". The newly created pack would be perfect for updating $active_pack by replacing it. Since pack-objects now knows how to do the rev-list's work itself internally, you can also write the above example by: pack-objects --unpacked=$active_pack --all $new_pack </dev/null Signed-off-by: Junio C Hamano <junkio@cox.net>	18 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	b8041fe4d8	Sparse-directory safety fix.

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
