* [PATCH] Make "git shortlog" understand raw logsLinus Torvalds2005-09-171-1/+1

* [PATCH] Fix "git-rev-list" revision range parsingLinus Torvalds2005-09-171-1/+3
| | | | | | | | | | | | There were two bugs in there: - if the range didn't end up working, we restored the '.' character in the wrong place. - an empty end-of-range should be interpreted as HEAD.

* Teach rsync transport about alternates.Junio C Hamano2005-09-173-5/+68
| | | | | | | | | | | | | | For local operations and downloading and uploading via git aware protocols, use of $GIT_OBJECT_DIRECTORY/info/alternates is recommended on the server side for big projects that are derived from another one (like Linux kernel). However, dumb protocols and rsync transport needs to resolve this on the client end, which we did not bother doing until this week. I noticed we use "rsync -z" but most of our payload is already compressed, which was not quite right. This commit also fixes it. Signed-off-by: Junio C Hamano <junkio@cox.net>
* [PATCH] Avoid building object ref lists when not neededLinus Torvalds2005-09-163-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The object parsing code builds a generic "this object references that object" because doing a full connectivity check for fsck requires it. However, nothing else really needs it, and it's quite expensive for git-rev-list that can have tons of objects in flight. So, exactly like the commit buffer save thing, add a global flag to disable it, and use it in git-rev-list.

Calculating the total object difference between two git revisions is still clearly the most expensive git operation (both in memory and CPU time), but it's now less than 40% of what it used to be.

* [PATCH] Improve git-rev-list memory usage furtherLinus Torvalds2005-09-161-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids keeping tree entries around, and free's them as it traverses the list. This avoids building up a huge memory footprint just for these small but very common allocations.

That is: Before: 42934 minor pagefaults After: 26718 minor pagefaults This is all in _addition_ to the previous fixes. It used to be ~48,000 pagefaults. That's still a honking big memory footprint, but it's about half of what it was just a day or two ago (and this is the object list for a pretty big update - almost 60,000 objects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The logic to calculate the full object list used to be very inter-twined with the logic that looked up the commits. For no good reason - it's actually a lot simpler to just do that logic as a separate pass. This improves performance a bit, and uses slightly less memory in my tests, but more importantly it makes the code simpler to work with and follow what it does. The performance win is less than I had hoped for, but I get: Before: [torvalds@g5 linux]$ /usr/bin/time git-rev-list --objects v2.6.12..HEAD | wc -l 13.64user 0.42system 0:14.13elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+47947minor)pagefaults 0swaps 58945 After: [torvalds@g5 linux]$ /usr/bin/time git-rev-list --objects v2.6.12..HEAD | wc -l 11.80user 0.36system 0:12.16elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+42684minor)pagefaults 0swaps 58945 ie it improved by 2 seconds, and took a 5000+ fewer pages (hey, that's 20MB out of 174MB to go). And got the same number of objects (in theory, the more expensive one might find some more shared objects to avoid. In practice it obviously doesn't). I know how to make it use _lots_ less memory, which will probably speed it up. But that's for another time, and I'd prefer to see this go in first.

* [PATCH] Avoid wasting memory in git-rev-listLinus Torvalds2005-09-153-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | This patch does proper quoting, and uses "env" to be compatible with tcsh. As a side benefit, I believe the code is a lot cleaner to read. [jc: I am accepting this not because I necessarily agree with the quoting approach taken by it, but because (1) the code is only used by ssh-fetch/ssh-upload pair which I do not care much about (if you have ssh account on the remote end you should be using git-send-pack git-fetch-pack pair over ssh anyway), and (2) HPA is one of the more important customers belonging to the Linux kernel community and I want to help his workflow -- which includes not wasting his time by asking him to switch to git-send-pack/git-fetch-pack pair, nor to use a better shell ;-).

* [PATCH] git-http-fetch: Allow caching of retrieved objects by proxy serversSergey Vlasov2005-09-151-0/+8
| | | | | | | | | | | | | | | By default the curl library adds "Pragma: no-cache" header to all requests, which disables caching by proxy servers. However, most files in a GIT repository are immutable, and caching them is safe and could be useful. This patch removes the "Pragma: no-cache" header from requests for all files except the pack list (objects/info/packs) and references (refs/*), which are really mutable and should not be cached.

| | | | | | | | | | | | | | | | | | | | | | | | | | An entry in the alternates file can name a directory relative to the object store it describes. A typical linux-2.6 maintainer repository would have "../../../torvalds/linux-2.6.git/objects" there, because the subsystem maintainer object store would live in /pub/scm/linux/kernel/git/$u/$system.git/objects/ and the object store of Linus tree is in /pub/scm/linux/kernel/git/torvalds/linux-2.6.git/objects/ This unfortunately is different from GIT_ALTERNATE_OBJECT_DIRECTORIES which is relative to the cwd of the running process, but there is no way to make it consistent with the behaviour of the environment variable. The process typically is run in $system.git/ directory for a naked repository, or one level up for a repository with a working tree, so we just define it to be relative to the objects/ directory to be different from either ;-). Later, the dumb transport could be updated to read from info/alternates and make requests for the repository the repository borrows from. Signed-off-by: Junio C Hamano <junkio@cox.net>

CDPATH mechanism does not implicitly give "." at the beginning of CDPATH, which is the most irritating part. * The extra echo when it does its thing confuses scripts further.

| | | | | | | | | | | | | | | | | | If you make a commit on a path, and then make the path cache-dirty afterwards without changing its contents, 'git checkout' to switch to another branch is prevented because switching the branches done with 'read-tree -m -u $current $next' detects that the path is cache-dirty, but it does not bother noticing that the contents of the path has not been actualy changed. Since switching branches would involve checking out paths different in the two branches, hence it is reasonably expensive operation, we can afford to run update-index before running read-tree to reduce this kind of false change from triggering the check needlessly.
