| * Add "named object array" conceptLinus Torvalds2006-06-1914-131/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've had this notion of a "object_list" for a long time, which eventually grew a "name" member because some users (notably git-rev-list) wanted to name each object as it is generated. That object_list is great for some things, but it isn't all that wonderful for others, and the "name" member is generally not used by everybody. This patch splits the users of the object_list array up into two: the traditional list users, who want the list-like format, and who don't actually use or want the name. And another class of users that really used the list as an extensible array, and generally wanted to name the objects. The patch is fairly straightforward, but it's also biggish. Most of it really just cleans things up: switching the revision parsing and listing over to the array makes things like the builtin-diff usage much simpler (we now see exactly how many members the array has, and we don't get the objects reversed from the order they were on the command line). One of the main reasons for doing this at all is that the malloc overhead of the simple object list was actually pretty high, and the array is just a lot denser. So this patch brings down memory usage by git-rev-list by just under 3% (on top of all the other memory use optimizations) on the mozilla archive. It does add more lines than it removes, and more importantly, it adds a whole new infrastructure for maintaining lists of objects, but on the other hand, the new dynamic array code is pretty obvious. The change to builtin-diff-tree.c shows a fairly good example of why an array interface is sometimes more natural, and just much simpler for everybody.

| * Add specialized object allocatorLinus Torvalds2006-06-197-5/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

It now contains /only/ the object flags and the SHA1 hash name of the object. The "refs" field, which is really needed only for fsck, is maintained in a separate hashed lookup-table, allowing all normal users to totally ignore it. This helps memory usage, although not as much as I hoped: it looks like the allocation overhead of malloc (and the alignment constraints in particular) means that while the structure size shrinks, the actual allocation overhead mostly does not. [ That said: memory usage is actually down, but not as much as it should be: I suspect just one of the object types actually ended up shrinking its effective allocation size. To get to the next level, we probably need specialized allocators that don't pad the allocation more than necessary. ] The separation makes for some code cleanup, though, and makes the ref tracking that fsck wants a clearly separate thing.

| * | Some more memory leak avoidanceLinus Torvalds2006-06-173-2/+14

It discards the parent lists and the commit buffer after the commit has been shown by git-rev-list (and "git log" - which already did the commit buffer part), and frees the commit list entry that was used by the revision walker. The big win would be to get rid of the "refs" pointer in the object structure (another 5%), because it's only used by fsck. That would require some pretty major surgery to fsck, though, so I'm timid and did the less interesting but much easier part instead. This (percentually) makes a bigger difference to "git log" and friends, since those are walking _just_ commits, and thus the list entries tend to be a bigger percentage of the memory use. But the "list all objects" case does improve too. 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 Torvalds2006-06-176-42/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
