* object-store: move object access functions to object-store.hStefan Beller2018-05-161-0/+1
| | | | | | | | | | | | | | | | | | | This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h. In this patch the #include is only added to files that would fail to compile otherwise. It would be better to #include wherever identifiers from the header are used. That can happen later when we have better tooling for it. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* cache.h: add repository argument to oid_object_infoStefan Beller2018-04-261-1/+1
| | | | | | | | | | | | | | Add a repository argument to allow the callers of oid_object_info to be more specific about which repository to handle. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. As with the previous commits, use a macro to catch callers passing a repository other than the_repository at compile time.

| | | | | | | | | | | | | | | | | | | | | | | | A common mistake when writing binary search is to allow possible integer overflow by using the simple average: mid = (min + max) / 2; Instead, use the overflow-safe version: mid = min + (max - min) / 2; This translation is safe since the operation occurs inside a loop conditioned on "min < max". The included changes were found using the following git grep: git grep '/ *2;' '*.c' Making this cleanup will prevent future review friction when a new binary search is contructed based on existing code.

Our doing so introduces inconsistency. * We do not insist on where the output should go, by saying git gostak [--distim] < <list-of-doshes> > <output> * As it is our convention to enclose placeholders inside <braket>, the redirection operator followed by a placeholder filename becomes very hard to read, both in the documentation and in the help text.

* fsck_object(): allow passing object data separately from the object itselfJohannes Schindelin2014-09-101-4/+10
| | | | | | | | | | | | | | | | | | | | | | When fsck'ing an incoming pack, we need to fsck objects that cannot be read via read_sha1_file() because they are not local yet (and might even be rejected if transfer.fsckobjects is set to 'true'). For commits, there is a hack in place: we basically cache commit objects' buffers anyway, but the same is not true, say, for tag objects. By refactoring fsck_object() to take the object buffer and size as optional arguments -- optional, because we still fall back to the previous method to look at the cached commit objects if the caller passes NULL -- we prepare the machinery for the upcoming handling of tag objects. The assumption that such buffers are inherently NUL terminated is now wrong, of course, hence we pass the size of the buffer so that we can add a sanity check later, to prevent running past the end of the buffer.

* zlib: zlib can only process 4GB at a timeJunio C Hamano2011-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The size of objects we read from the repository and data we try to put into the repository are represented in "unsigned long", so that on larger architectures we can handle objects that weigh more than 4GB. But the interface defined in zlib.h to communicate with inflate/deflate limits avail_in (how many bytes of input are we calling zlib with) and avail_out (how many bytes of output from zlib are we ready to accept) fields effectively to 4GB by defining their type to be uInt. In many places in our code, we allocate a large buffer (e.g. mmap'ing a large loose object file) and tell zlib its size by assigning the size to avail_in field of the stream, but that will truncate the high octets of the real size. The worst part of this story is that we often pass around z_stream (the state object used by zlib) to keep track of the number of used bytes in input/output buffer by inspecting these two fields, which practically limits our callchain to the same 4GB limit. Wrap z_stream in another structure git_zstream that can express avail_in and avail_out in unsigned long. For now, just die() when the caller gives a size that cannot be given to a single zlib call. In later patches in the series, we would make git_inflate() and git_deflate() internally loop to give callers an illusion that our "improved" version of zlib interface can operate on a buffer larger than 4GB in one go.

* Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds2010-02-221-0/+568
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>
