Shawn O. Pearce	dc49cd769b	Cast 64 bit off_t to 32 bit size_t Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4. This implies that we are able to access and work on files whose maximum length is around 2^63-1 bytes, but we can only malloc or mmap somewhat less than 2^32-1 bytes of memory. On such a system an implicit conversion of off_t to size_t can cause the size_t to wrap, resulting in unexpected and exciting behavior. Right now we are working around all gcc warnings generated by the -Wshorten-64-to-32 option by passing the off_t through xsize_t(). In the future we should make xsize_t on such problematic platforms detect the wrapping and die if such a file is accessed. Signed-off-by: Shawn O.

Junio C Hamano	ae72f68541	count-objects -v: show number of packs as well. Recent "git push" keeps transferred objects packed much more aggressively than before. Monitoring output from git-count-objects -v for number of loose objects is not enough to decide when to repack -- having too many small packs is also a good cue for repacking.

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
Junio C Hamano	f754fa9c54	builtins: Makefile clean-up This cleans up the build procedure for built-in commands by: - generating mostly redundant definition of BUILT_INS from BUILTIN_OBJS in the Makefile, - renaming a few files to make the above possible, and - sorting the built-in command table in git.c. It might be a good idea to binary search (or perfect hash) the built-in command table, but that can be done later when somebody feels like. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	a633fca0c0	Call setup_git_directory() much earlier This changes the calling convention of built-in commands and passes the "prefix" (i.e. pathname of $PWD relative to the project root level) down to them.

Junio C Hamano	80fe7d2b54	builtin-count-objects: open packs when running -v Otherwise we would report absolutely no objects in a fully packed repository. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	c74320872b	built-in count-objects. Also it learned to do -v (verbose) to report: - number of loose objects - disk occupied by loose objects - number of objects in local packs - number of loose objects that are also in pack - unrecognised garbage in .git/objects/??/.
