Andreas Ericsson 5dddf7c8 2010-04-14T20:41:57 Add block-sha1 in favour of the mozilla routines Since block-sha1 from git.git has such excellent performance, we can also get rid of the openssl dependency. It's rather simple to add it back later as an optional extra, but we really needn't bother to pull in the entire ssl library and have to deal with linking issues now that we have the portable and, performance-wise, truly excellent block-sha1 code to fall back on. Since this requires a slight revamp of the build rules anyway, we take the opportunity to fix including EXTRA_OBJS in the final build as well. The block-sha1 code was originally implemented for git.git by Linus Torvalds <torvalds@linux-foundation.org> and was later polished by Nicolas Pitre <nico@cam.org>.

Shawn O. Pearce 64a47c01 2008-12-30T23:21:36 Wrap malloc and friends and report out of memory as GIT_ENOMEM We now forbid direct use of malloc, strdup or calloc within the library and instead use wrapper functions git__malloc, etc. to invoke the underlying library malloc and set git_errno to a no memory error code if the allocation fails. In the future once we have pack objects in memory we are likely to enhance these routines with garbage collection logic to purge cached pack data when allocations fail. Because the size of the function will grow somewhat large, we don't want to mark them for inline as gcc tends to aggressively inline, creating larger than expected executables.
