* | | | | git-apply: Do not free the wrong buffer when we convert the data for writeoutJunio C Hamano2007-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we write out the result of patch application, we sometimes need to munge the data (e.g. under core.autocrlf). After doing so, what we should free is the temporary buffer that holds the converted data returned from convert_to_working_tree(), not the original one. This patch also moves the call to open() up in the function, as the caller expects us to fail cheaply if leading directories need to be created (and then the caller creates them and calls us again). For that calling pattern, attempting conversion before opening the file adds unnecessary overhead.

You have to say something unwieldly like this instead: $ git rebase $(git rev-parse HEAD) master This fixes it by expanding the $onto commit name before switching to the target branch.

* | | | | tree_entry_interesting(): allow it to say "everything is interesting"Junio C Hamano2007-03-22

* | | | | Switch over tree descriptors to contain a pre-parsed entryLinus Torvalds2007-03-21

On some benchmarks, it improves performance by up to 15%. That makes tree entry "extract" trivial, and means that we only actually need to decode each tree entry just once: we decode the first one when we initialize the tree descriptor, and each subsequent one when doing "update_tree_entry()". In particular, this means that we don't need to do strlen() both at extract time _and_ at update time. Finally, it also allows more sharing of code (entry_extract(), that wanted a "struct name_entry", just got totally trivial, along with the "tree_entry()" function).

Also renamed the "desc.buf" field to "desc.buffer" just to trigger compiler errors for old-style manual initializations, making sure I didn't miss anything.

That should all work, but the fact is, it's not how you're _supposed_ to use the zlib return values properly: - deflate() should never return Z_OK in the first place, except if we need to increase the output buffer size (which we're not doing, and should never need to do, since we pre-allocated a buffer that is supposed to be able to hold the output in full). So the "while()" loop was incorrect: Z_OK doesn't actually mean "ok, continue", it means "ok, allocate more memory for me and continue"! - if we got an error return, we would consider it to be end-of-stream, but it could be some internal zlib error. In short, we should check for Z_STREAM_END explicitly, since that's the only valid return value anyway for the Z_FINISH case. - we never checked deflateEnd() return codes at all. Now, admittedly, none of these issues should ever happen, unless there is some internal bug in zlib. So this patch should make zero difference, but it seems to be the right thing to do. We should probablybe anal and check the return value of "deflateInit()" too! Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

This was ensured by always unpacking the packfile received over the network (both in fetch and receive-pack) and our already existing logic to not create a loose object for an object we already have. Lately however we keep "large-ish" packfiles on both fetch and push by running them through index-pack instead of unpack-objects. This would let an attacker perform a birthday attack. How? Assume the attacker knows a SHA-1 that has two different data streams. He knows the client is likely to have the "good" one. So he sends the "evil" variant to the other end as part of a "large-ish" packfile. The recipient keeps that packfile, and indexes it. Now since this is a birthday attack there is a SHA-1 collision; two objects exist in the repository with the same SHA-1. They have *very* different data streams. One of them is "evil". Currently the poor recipient cannot tell the two objects apart, short of by examining the timestamp of the packfiles. But lets say the recipient repacks before he realizes he's been attacked. We may wind up packing the "evil" version of the object, and deleting the "good" one. This is made *even more likely* by Junio's recent rearrange_packed_git patch (b867092f). It is extremely unlikely for a SHA1 collisions to occur, but if it ever happens with a remote (hence untrusted) object we simply must not let the fetch succeed. Normally received packs should not contain objects we already have. But when they do we must ensure duplicated objects with the same SHA1 actually contain the same data.

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.

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.

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.
