2007-03-19GIT 1.5.1-rc1Libravatar Junio C Hamano2-2/+50
I think we can start to slow down, as we now have covered everything I listed earlier in the short-term release plan. The last release 1.5.0 took painfully too long. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-03-19Fix merge-indexLibravatar Junio C Hamano1-1/+2
An earlier conversion to run_command() from execlp() forgot that run_command() takes an array that is terminated with NULL. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-03-19Set up for better tree diff optimizationsLibravatar Linus Torvalds1-10/+34
This is mainly just a cleanup patch, and sets up for later changes where the tree-diff.c "interesting()" function can return more than just a yes/no value. In particular, it should be quite possible to say "no subsequent entries in this tree can possibly be interesting any more", and thus allow the callers to short-circuit the tree entirely. In fact, changing the callers to do so is trivial, and is really all this patch really does, because changing "interesting()" itself to say that nothing further is going to be interesting is definitely more complicated, considering that we may have arbitrary pathspecs. But in cleaning up the callers, this actually fixes a potential small performance issue in diff_tree(): if the second tree has a lot of uninterestign crud in it, we would keep on doing the "is it interesting?" check on the first tree for each uninteresting entry in the second one. The answer is obviously not going to change, so that was just not helping. The new code is clearer and simpler and avoids this issue entirely. I also renamed "interesting()" to "tree_entry_interesting()", because I got frustrated by the fact that - we actually had *another* function called "interesting()" in another file, and I couldn't tell from the profiles which one was the one that mattered more. - when rewriting it to return a ternary value, you can't just do if (interesting(...)) ... any more, but want to assign the return value to a local variable. The name of choice for that variable would normally be "interesting", so I just wanted to make the function name be more specific, and avoid that whole issue (even though I then didn't choose that name for either of the users, just to avoid confusion in the patch itself ;) In other words, this doesn't really change anything, but I think it's a good thing to do, and if somebody comes along and writes the logic for "yeah, none of the pathspecs you have are interesting", we now support that trivially. It could easily be a meaningful optimization for things like "blame", where there's just one pathspec, and stopping when you've seen it would allow you to avoid about 50% of the tree traversals on average.

2007-03-19Trivial cleanup of track_tree_refs()Libravatar Linus Torvalds1-3/+1
This makes "track_tree_refs()" use the same "tree_entry()" function for counting the entries as it does for actually traversing them a few lines later. Not a biggie, but the reason I care was that this was the only user of "update_tree_entry()" that didn't actually *extract* the tree entry first. It doesn't matter as things stand now, but it meant that a separate test-patch I had that avoided a few more "strlen()" calls by just saving the entry length in the entry descriptor and using it directly when updating wouldn't work without this patch.

2007-03-18Limit the size of the new delta_base_cacheLibravatar Shawn O. Pearce5-4/+46
The new configuration variable core.deltaBaseCacheLimit allows the user to control how much memory they are willing to give to Git for caching base objects of deltas. This is not normally meant to be a user tweakable knob; the "out of the box" settings are meant to be suitable for almost all workloads. We default to 16 MiB under the assumption that the cache is not meant to consume all of the user's available memory, and that the cache's main purpose was to cache trees, for faster path limiters during revision traversal. Since trees tend to be relatively small objects, this relatively small limit should still allow a large number of objects. On the other hand we don't want the cache to start storing 200 different versions of a 200 MiB blob, as this could easily blow the entire address space of a 32 bit process. We evict OBJ_BLOB from the cache first (credit goes to Junio) as we want to favor OBJ_TREE within the cache. These are the objects that have the highest inflate() startup penalty, as they tend to be small and thus don't have that much of a chance to ammortize that penalty over the entire data.

2007-03-18Avoid unnecessary strlen() callsLibravatar Linus Torvalds3-29/+36
This is a micro-optimization that grew out of the mailing list discussion about "strlen()" showing up in profiles. We used to pass regular C strings around to the low-level tree walking routines, and while this worked fine, it meant that we needed to call strlen() on strings that the caller always actually knew the size of anyway. So pass the length of the string down wih the string, and avoid unnecessary calls to strlen(). Also, when extracting a pathname from a tree entry, use "tree_entry_len()" instead of strlen(), since the length of the pathname is directly calculable from the decoded tree entry itself without having to actually do another strlen(). This shaves off another ~5-10% from some loads that are very tree intensive (notably doing commit filtering by a pathspec).

2007-03-18Reuse cached data out of delta base cache.Libravatar Nicolas Pitre1-4/+10
A malloc() + memcpy() will always be faster than mmap() + malloc() + inflate(). If the data is already there it is certainly better to copy it straight away. With this patch below I can do 'git log drivers/scsi/ > /dev/null' about 7% faster. I bet it might be even more on those platforms with bad mmap() support.

This trivial 256-entry delta_base cache improves performance for some loads by a factor of 2.5 or so. Instead of always re-generating the delta bases (possibly over and over and over again), just cache the last few ones. They often can get re-used.

2007-03-16[PATCH] clean up pack index handling a bitLibravatar Nicolas Pitre6-87/+90
Especially with the new index format to come, it is more appropriate to encapsulate more into check_packed_git_idx() and assume less of the index format in struct packed_git. To that effect, the index_base is renamed to index_data with void * type so it is not used directly but other pointers initialized with it. This allows for a couple pointer cast removal, as well as providing a better generic name to grep for when adding support for new index versions or formats. And index_data is declared const too while at it. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-03-16git-fetch, git-branch: Support local --track via a special remote '.'Libravatar Paolo Bonzini7-22/+79
This patch adds support for a dummy remote '.' to avoid having to declare a fake remote like [remote "local"] url = . fetch = refs/heads/*:refs/heads/* Such a builtin remote simplifies the operation of "git-fetch", which will populate FETCH_HEAD but will not pretend that two repositories are in use, will not create a thin pack, and will not perform any useless remapping of names. The speed improvement is around 20%, and it should improve more if "git-fetch" is converted to a builtin. To this end, git-parse-remote is grown with a new kind of remote, 'builtin'. In git-fetch.sh, we treat the builtin remote specially in that it needs no pack/store operations. In fact, doing git-fetch on a builtin remote will simply populate FETCH_HEAD appropriately. The patch also improves of the --track/--no-track support, extending it so that branch.<name>.remote items referring '.' can be created. Finally, it fixes a typo in git-checkout.sh.

2007-03-14try-to-simplify-commit: use diff-tree --quiet machinery.Libravatar Junio C Hamano1-0/+6
This uses diff-tree --quiet machinery to terminate the internal diff-tree between a commit and its parents via revs.pruning (not revs.diffopt) as soon as we find enough about the tree change. With respect to the optionally given pathspec, we are interested if the tree of commit is identical to the parent's, only adds new paths to the parent's, or there are other differences. As soon as we find out that there is one such other kind of difference, we do not have to compare the rest of the tree. Because we do not call standard diff_addremove/diff_change, we instruct the diff-tree machinery to stop early by setting has_changes when we say we found the trees to be different.

2007-03-14diff --quietLibravatar Junio C Hamano2-4/+27
This adds the command line option 'quiet' to tell 'git diff-*' that we are not interested in the actual diff contents but only want to know if there is any change. This option automatically turns --exit-code on, and turns off output formatting, as it does not make much sense to show the first hit we happened to have found. The --quiet option is silently turned off (but --exit-code is still in effect, so is silent output) if postprocessing filters such as pickaxe and diff-filter are used. For all practical purposes I do not think of a reason to want to use these filters and not viewing the diff output. The backends have not been taught about the option with this patch. That is a topic for later rounds. Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-03-14update-hook: fix incorrect use of git-describe and sed for finding previous tagLibravatar Andy Parkins1-1/+1
Previously git-describe would output lines of the form v1.1.1-gf509d56 The update hook found the dash and stripped it off using sed 's/-g.*//' The remainder was then used as the previous tag name. However, git-describe has changed format. The output is now of the form v1.1.1-23-gf509d56 The above sed fragment doesn't strip the middle "-23", and so the previous tag name used would be "v1.1.1-23". This is incorrect. Since the hook script was written, git-describe now gained support for "--abbrev=0", which it uses as a special flag to tell it not to output anything other than the nearest tag name. This patch fixes the problem, and prevents any future recurrence by using this new flag rather than sed to find the previous tag.
