2023-06-21object-store-ll.h: split this header out of object-store.hElijah Newren
The vast majority of files including object-store.h did not need dir.h nor khash.h. Split the header into two files, and let most just depend upon object-store-ll.h, while letting the two callers that need it depend on the full object-store.h. After this patch: $ git grep -h include..object-store | sort | uniq -c 2 #include "object-store.h" 129 #include "object-store-ll.h" Diff best viewed with `--color-moved`.

2023-03-21treewide: be explicit about dependence on gettext.hElijah Newren
Dozens of files made use of gettext functions, without explicitly including gettext.h. This made it more difficult to find which files could remove a dependence on cache.h. Make C files explicitly include gettext.h if they are using it. However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an include of gettext.h, it was left out to avoid conflicting with an in-flight topic.

2023-03-21treewide: remove unnecessary cache.h inclusion from a few headersElijah Newren
Ever since a64215b6cd ("object.h: stop depending on cache.h; make cache.h depend on object.h", 2023-02-24), we have a few headers that could have replaced their include of cache.h with an include of object.h. Make that change now. Some C files had to start including cache.h after this change (or some smaller header it had brought in), because the C files were depending on things from cache.h but were only formerly implicitly getting cache.h through one of these headers being modified in this patch.

2023-02-24treewide: ensure one of the appropriate headers is sourced firstElijah Newren
We had several C files ignoring the rule to include one of the appropriate headers first; fix that. While at it, the rule in Documentation/CodingGuidelines about which header to include has also fallen out of sync, so update the wording to mention other allowed headers. Unfortunately, C files in reftable/ don't actually follow the previous or updated rule. If you follow the #include chain in its C files, reftable/system.h _tends_ to be first (i.e. record.c first includes record.h, which first includes basics.h, which first includees system.h), but not always (e.g. publicbasics.c includes another header first that does not include system.h). However, I'm going to punt on making actual changes to the C files in reftable/ since I do not want to risk bringing it out-of-sync with any version being used externally.

2020-03-25Lib-ify prune-packedDenton Liu
In builtin.h, there exists the distinctly lib-ish function prune_packed_objects(). This function can currently only be called by built-in commands but, unlike all of the other functions in the header, it does not make sense to impose this restriction as the functionality can be logically reused in libgit. Extract this function into prune-packed.c so that related definitions can exist clearly in their own header file. While we're at it, clean up #includes that are unused. This patch is best viewed with --color-moved. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2005-10-29Be marginally more careful about removing objectsLinus Torvalds
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>
2005-10-28Create object subdirectories on demand (phase II)Linus Torvalds
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.

2005-10-17Sparse-directory safety fix.Junio C Hamano
This will be removed when merging the second phase of Linus' "Create object subdirectories on demand" change anyway, but the code to recreate the empty .git/objects/??/ directory was confused. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-09Create object subdirectories on demandLinus Torvalds
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>
