* Re-fix clear_commit_marks().Junio C Hamano2006-07-04
| | | | | | | Fix clear_commit_marks() enough to be usable in get_merge_bases(), and retire now unused clear_object_marks(). Signed-off-by: Junio C Hamano <junkio@cox.net>
* revert clear-commit-marks for now.Junio C Hamano2006-07-03
| | | | | | | | | Earlier change broke "git describe A B" among other things. Revert it for now, and clean the commits smudged by get_merge_bases using clear_object_marks() function. For complex commit ancestry graph, this is way cheaper as well. Signed-off-by: Junio C Hamano <junkio@cox.net>

* Fold get_merge_bases_clean() into get_merge_bases()Rene Scharfe2006-07-02
| | | | | | | | | | | | | | Change get_merge_bases() to be able to clean up after itself if needed by adding a cleanup parameter. We don't need to save the flags and restore them afterwards anymore; that was a leftover from before the flags were moved out of the range used in revision.c. clear_commit_marks() sets them to zero, which is enough.

* Add get_merge_bases_clean()Rene Scharfe2006-07-01
| | | | | | | | | | | | | | | Add get_merge_bases_clean(), a wrapper for get_merge_bases() that cleans up after doing its work and make get_merge_bases() NOT clean up. Single-shot programs like git-merge-base can use the dirty and fast version. Also move the object flags used in get_merge_bases() out of the range defined in revision.h. This fixes the "66ae0c77...ced9456a 89719209...262a6ef7" test of the ... operator which is introduced with the next patch.

* Add specialized object allocatorLinus Torvalds2006-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a simple specialized object allocator for basic objects. This avoids wasting space with malloc overhead (metadata and extra alignment), since the specialized allocator knows the alignment, and that objects, once allocated, are never freed. It also allows us to track some basic statistics about object allocations. For example, for the mozilla import, it shows object usage as follows: blobs: 627629 (14710 kB) trees: 1119035 (34969 kB) commits: 196423 (8440 kB) tags: 1336 (46 kB) and the simpler allocator shaves off about 2.5% off the memory footprint off a "git-rev-list --all --objects", and is a bit faster too. [ Side note: this concludes the series of "save memory in object storage". The thing is, there simply isn't much more to be saved on the objects. Doing "git-rev-list --all --objects" on the mozilla archive has a final total RSS of 131498 pages for me: that's about 513MB. Of that, the object overhead is now just 56MB, the rest is going somewhere else (put another way: the fact that this patch shaves off 2.5% of the total memory overhead, considering that objects are now not much more than 10% of the total shows how big the wasted space really was: this makes object allocations much more memory- and time-efficient). I haven't looked at where the rest is, but I suspect the bulk of it is just the pack-file loading. It may be that we should pack the tree objects separately from the blob objects: for git-rev-list --objects, we don't actually ever need to even look at the blobs, but since trees and blobs are interspersed in the pack-file, we end up not being dense in the tree accesses, so we end up looking at more pages than we strictly need to. So with a 535MB pack-file, it's entirely possible - even likely - that most of the remaining RSS is just the mmap of the pack-file itself. We don't need to map in _all_ of it, but we do end up mapping a fair amount. ] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* Move "void *util" from "struct object" into "struct commit"Linus Torvalds2006-06-17
| | | | | | | | | | | | | | | | | Every single user actually wanted this only for commit objects, and we have no reason to waste space on it for other object types. So just move the structure member from the low-level "struct object" into the "struct commit". This leaves the commit object the same size, and removes one unnecessary pointer from all other object allocations. This shrinks memory usage (still at a fairly hefty half-gig, admittedly) of "git-rev-list --all --objects" on the mozilla repo by another 5% in my tests.

* Shrink "struct object" a bitLinus Torvalds2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shrinks "struct object" by a small amount, by getting rid of the "struct type *" pointer and replacing it with a 3-bit bitfield instead. In addition, we merge the bitfields and the "flags" field, which incidentally should also remove a useless 4-byte padding from the object when in 64-bit mode. Now, our "struct object" is still too damn large, but it's now less obviously bloated, and of the remaining fields, only the "util" (which is not used by most things) is clearly something that should be eventually discarded. This shrinks the "git-rev-list --all" memory use by about 2.5% on the kernel archive (and, perhaps more importantly, on the larger mozilla archive). That may not sound like much, but I suspect it's more on a 64-bit platform. There are other remaining inefficiencies (the parent lists, for example, probably have horrible malloc overhead), but this was pretty obvious. Most of the patch is just changing the comparison of the "type" pointer from one of the constant string pointers to the appropriate new TYPE_xxx small integer constant.

* Fix git-rev-list "date order" with --topo-orderLinus Torvalds2005-11-14
| | | | | | | | | | | | | | | | | | | | This fixes git-rev-list so that when there are multiple branches, we still sort the heads in proper approximate date order even when sorting the output topologically. This makes things like gitk --all -d work sanely and show the branches in date order (where "date order" is obviously modified by the paren-child dependency requirements of the topological sort).

* [PATCH] Avoid wasting memory in git-rev-listLinus Torvalds2005-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As pointed out on the list, git-rev-list can use a lot of memory. One low-hanging fruit is to free the commit buffer for commits that we parse. By default, parse_commit() will save away the buffer, since a lot of cases do want it, and re-reading it continually would be unnecessary. However, in many cases the buffer isn't actually necessary and saving it just wastes memory. We could just free the buffer ourselves, but especially in git-rev-list, we actually end up using the helper functions that automatically add parent commits to the commit lists, so we don't actually control the commit parsing directly. Instead, just make this behaviour of "parse_commit()" a global flag. Maybe this is a bit tasteless, but it's very simple, and it makes a noticable difference in memory usage.
