The "score" calculation for diffcore-rename was totally broken.
It scaled "score" as
score = src_copied * MAX_SCORE / dst->size;
which means that you got a 100% similarity score even if src and dest were
different, if just every byte of dst was copied from src, even if source
was much larger than dst (eg we had copied 85% of the bytes, but _deleted_
the remaining 15%).
That's clearly bogus. We should do the score calculation relative not to
the destination size, but to the max size of the two.
This seems to fix it.

This tweaks the maximum hashvalue we use to hash the string into
without making the maximum size of the hashtable can grow from
the current limit. With this, the renames detected becomes a
bit more precise without incurring additional paging cost.

To reduce wasted memory, wait until the hash fills up more
densely before we rehash. This reduces the working set size a
bit further.

Marco Costalba reports that --remove-empty omits the commit that
created paths we are interested in. try_to_simplify_commit()
logic was dropping a parent we introduced those paths against,
which I think is not what we meant. Instead, this makes such
parent parentless.

This changes diffcore-rename to reuse statistics information
gathered during similarity estimation, and updates the hashtable
implementation used to keep track of the statistics to be
denser. This seems to give better performance.

Some versions of gcc check that calls to the exec() family have the proper
sentinel for variadic calls. This should be (char *) NULL according to the
man page. Although for all other purposes the 0 is equivalent, gcc
nevertheless does emit a warning for 0 and not for NULL. This also makes the
usage consistent throughout git.
The whitespace in function calls throughout imap-send.c has its own style,
so I left it that way.

RPM, at least on Fedora boxes, automatically creates a
dependency for any perl "use" lines, and one of the help text
lines unfortunately begins like this:
-S, --rev-file revs-file
use revs from revs-file instead of calling git-rev-list
RPM gets confused and creates a false dependecy for the
nonexistent perl package "revs". Obviously this creates a
problem when someone goes to install the git-core rpm.
Since other help sentences all start with capital letter, make
this one match them by upcasing "Use". As a side effect, RPM
stops getting confused.

git-imap-send drops a patch series generated by git-format-patch into an
IMAP folder. This allows patch submitters to send patches through their
own mail program.
git-imap-send uses the following values from the GIT repository
configuration:
The target IMAP folder:
[imap]
Folder = "INBOX.Drafts"
A command to open an ssh tunnel to the imap mail server.
[imap]
Tunnel = "ssh -q user@imap.server.com /usr/bin/imapd ./Maildir
2> /dev/null"
[imap]
Host = imap.server.com
User = bob
Password = pwd
Port = 143
When git-rev-list (and git-log) collapsed ancestry chain to
commits that touch specified paths, we failed to inspect and
notice tree changes when we are about to hit uninteresting
parent. This resulted in "git rev-list since.. -- file" to
always show the child commit after the lower bound, even if it
does not touch the file. This commit fixes it.
Thanks for Catalin for reporting this.

The fsck-objects command (back then it was called fsck-cache)
used to complain if objects referred to by files in .git/refs/
or objects stored in files under .git/objects/??/ were not found
as stand-alone SHA1 files (i.e. found in alternate object pools
or packed archives stored under .git/objects/pack). Back then,
packs and alternates were new curiosity and having everything as
loose objects were the norm.
When we adjusted the behaviour of fsck-cache to consider objects
found in packs are OK, we introduced the --standalone flag as a
backward compatibility measure.
It still correctly checks if your repository is complete and
consists only of loose objects, so in that sense it is doing the
"right" thing, but checking that is pointless these days. This
commit removes --standalone flag.

'svn info' doesn't work with URLs in svn <= 1.1. Now we

As a side effect, this should also work better for 'init' off
directories that are no longer in the latest revision of the
repository.
svn checkout -r<revision> arguments are fixed.
Newer versions of svn (1.2.x) seem to need URL@REV as well as
-rREV to checkout a particular revision...

The diff-delta code can exhibit O(m*n) behavior with some patological
data set where most hash entries end up in the same hash bucket.
To prevent this, a limit is imposed to the number of entries that can
exist in the same hash bucket.
Because of the above the code is a tiny bit more expensive on average,
even if some small optimizations were added as well to atenuate the
overhead. But the problematic samples used to diagnoze the issue are now
orders of magnitude less expensive to process with only a slight loss in
compression.
