Alexander Potashev	8ca12c0d62	add is_dot_or_dotdot inline function A new inline function is_dot_or_dotdot is used to check if the directory name is either "." or "..". It returns a non-zero value if the given string is "." or "..". It's applicable to a lot of Git source code.

Mikael Magnusson	bfd083b734	Correct output of git-count-objects. The non-verbose output was not changed in `fdb2a2a` (compat: introduce on_disk_bytes(), 2008-08-18) which caused git-count-objects to claim 512 times too much space used for loose objects.

Junio C Hamano	fdb2a2a600	compat: introduce on_disk_bytes() Some platforms do not have st_blocks member in "struct stat"; mingw already emulates it by rounding it up to closest 512-byte blocks (even though it could overcount when a file has holes). The reason to use the member is only to figure out how many kilobytes the files occupy on-disk, so give a helper function in git-compat-util.h to compute this value.

Marcus Griep	f223824943	count-objects: Add total pack size to verbose output Adds the total pack size (including indexes) the verbose count-objects output, floored to the nearest kilobyte. Updates documentation to match this addition. Signed-off-by: Marcus Griep <marcus@griep.us> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 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.

Shawn O. Pearce	eaa8677039	Simplify index access condition in count-objects, pack-redundant My earlier lazy index opening patch changed this condition to check index_data and call open_pack_index if it was NULL. In truth we only care about num_objects. Since open_pack_index does no harm if the index is already open, and all indexes are likely to be closed in this application, the "performance optimization" of inlining the index_data check here was wrong.

Shawn O. Pearce	d079837eee	Lazily open pack index files on demand In some repository configurations the user may have many packfiles, but all of the recent commits/trees/tags/blobs are likely to be in the most recent packfile (the one with the newest mtime). It is therefore common to be able to complete an entire operation by accessing only one packfile, even if there are 25 packfiles available to the repository. Rather than opening and mmaping the corresponding .idx file for every pack found, we now only open and map the .idx when we suspect there might be an object of interest in there. Of course we cannot known in advance which packfile contains an object, so we still need to scan the entire packed_git list to locate anything. But odds are users want to access objects in the most recently created packfiles first, and that may be all they ever need for the current operation. Junio observed in `b867092f` that placing recent packfiles before older ones can slightly improve access times for recent objects, without degrading it for historical object access. This change improves upon Junio's observations by trying even harder to avoid the .idx files that we won't need. Signed-off-by: Shawn O.

Nicolas Pitre	57059091fa	get rid of num_packed_objects() The coming index format change doesn't allow for the number of objects to be determined from the size of the index file directly. Instead, Let's initialize a field in the packed_git structure with the object count when the index is validated since the count is always known at that point. While at it let's reorder some struct packed_git fields to avoid padding due to needed 64-bit alignment for some of them.

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>	19 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

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/??/.
