Maybe we would want to make this default before it graduates to the master branch, but in the meantime to help testing things, this allows you to say "git push --thin destination". Signed-off-by: NJunio C Hamano <junkio@cox.net>

The new flag loosens the usual "self containedness" requirment of packfiles, and sends deltified representation of objects when we know the other side has the base objects needed to unpack them. This would help reducing the transfer size. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This goes together with "rev-list --object-edge" change, to feed pack-objects list of edge commits in addition to the usual object list. Upon seeing such list, pack-objects loosens the usual "self contained delta" constraints, and can produce delta against blobs and trees contained in the edge commits without storing the delta base objects themselves. The resulting packfile is not usable in .git/object/packs, but is a good way to implement "delta-only" transfer. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This tries to rework the solution for the excess delta chain problem. An earlier commit worked it around ``cheaply'', but repeated repacking risks unbound growth of delta chains. This version counts the length of delta chain we are reusing from the existing pack, and makes sure a base object that has sufficiently long delta chain does not get deltified.

A new flag -q makes underlying pack-objects less chatty. A new flag -f forces delta to be recomputed from scratch. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This introduces --no-reuse-delta option to disable reusing of existing delta, which is a large part of the optimization introduced by this series. This may become necessary if repeated repacking makes delta chain too long. With this, the output of the command becomes identical to that of the older implementation. But the performance suffers greatly. It still allows reusing non-deltified representations; there is no point uncompressing and recompressing the whole text. It also adds a couple more statistics output, while squelching it under -q flag, which the last round forgot to do. $ time old-git-pack-objects --stdout >/dev/null <RL Generating pack...

It can create delta chains that are deeper than specified. A<--B<--C<--D E F G Suppose we have a delta chain A to D (A is stored in full either in a pack or as a loose object. B is depth1 delta relative to A, C is depth2 delta relative to B...) with loose objects E, F, G. And we are going to pack all of them. B, C and D are left as delta against A, B and C respectively. So A, E, F, and G are examined for deltification, and let's say we decided to keep E expanded, and store the rest as deltas like this: E<--F<--G<--A Oops. We ended up making D a bit too deep, didn't we? B, C and D form a chain on top of A! This is because we did not know what the final depth of A would be, when we checked objects and decided to keep the existing delta. Unfortunately, deferring the decision until just before the deltification is not an option. To be able to make B, C, and D candidates for deltification with the rest, we need to know the type and final unexpanded size of them, but the major part of the optimization comes from the fact that we do not read the delta data to do so -- getting the final size is quite an expensive operation. To prevent this from happening, we should keep A from being deltified. But how would we tell that, cheaply? To do this most precisely, after check_object() runs, each object that is used as the base object of some existing delta needs to be marked with the maximum depth of the objects we decided to keep deltified (in this case, D is depth 3 relative to A, so if no other delta chain that is longer than 3 based on A exists, mark A with 3). Then when attempting to deltify A, we would take that number into account to see if the final delta chain that leads to D becomes too deep. However, this is a bit cumbersome to compute, so we would cheat and reduce the maximum depth for A arbitrarily to depth/4 in this implementation. Signed-off-by: NJunio C Hamano <junkio@cox.net>

When generating a new pack, notice if we have already needed objects in existing packs. If an object is stored deltified, and its base object is also what we are going to pack, then reuse the existing deltified representation unconditionally, bypassing all the expensive find_deltas() and try_deltas() calls. Also, notice if what we are going to write out exactly match what is already in an existing pack (either deltified or just compressed). In such a case, we can just copy it instead of going through the usual uncompressing & recompressing cycle.

We run svn log against a URL without a working copy for the first fetch, so we end up a log that's sorted from highest to lowest. That's bad, we always want lowest to highest. Just default to --revision 0:HEAD now if -r isn't specified for the first fetch. Also sort the revisions after we get them just in case somebody accidentally reverses the argument to --revision for whatever reason. Thanks again to Emmanuel Guerin for helping me find this.

When you say "git commit Documentaiton" to make partial commit for the files only in that directory, we did not detect that as a misspelled pathname and attempted to commit index without change. If nothing matched, there is no harm done, but if the index gets modified otherwise by having another valid pathspec or after an explicit update-index, a user will not notice without paying attention to the "git status" preview. This introduces --error-unmatch option to ls-files, and uses it to detect this common user error. Signed-off-by: NJunio C Hamano <junkio@cox.net>

When showing a conflicted merge from index stages and working tree file, we did not fetch the mode from the working tree, and mistook that as a deleted file.
