Ack, ack.
There's another easy 5% or so for the built-in object walker: once we've
created the hash from the name, the name isn't interesting any more, and
so something trivial like this can help a bit.
Does it matter? Probably not on its own. But a few more memory saving
tricks and it might all make a difference.

This test was added recently (5a688fe, "core.sharedrepository = 0mode"
should set, not loosen; 2009-03-28). It checked the result of a sed
invocation for emptyness, but in some cases it forgot to print anything
at all, so that those checks would never be false.
Due to this mistake, it went unnoticed that the files in objects/info are
not necessarily 0440, but can also be 0660. Because the 0mode setting
tries to guarantee that the files are accessible only to the people they
are meant to be used by, we should only make sure that they are readable
by the user and the group when the configuration is set to 0660. It is a
separate matter from the core.shredrepository settings that w-bit from
immutable object files under objects/[0-9a-f][0-9a-f] directories should
be dropped.
COMMIT_EDITMSG is still world-readable, but it (and any transient files
that are meant for repositories with a work tree) does not matter. If you
are working on a shared machine and on a sekrit stuff, the root of the
work tree would be with mode 0700 (or 0750 to allow peeking by other
people in the group), and that would mean that .git/COMMIT_EDITMSG in such
a repository would not be readable by the strangers anyway.
Also, in the real-world use case, .git/COMMIT_EDITMSG will be given to an
arbitrary editor the user happens to use, and we have no guarantee what it
does (e.g. it may create a new file with umask and replace, it may rewrite
in place, it may leave an editor backup file but use umask to create it,
etc.), and the protection of the file lies majorly on the protection of
the root of the work tree.
This test cannot be run on Windows; it requires POSIXPERM when merged to
'master'.

With "git add -e [<files>]", Git will fire up an editor with the current
diff relative to the index (i.e. what you would get with "git diff
[<files>]").
Now you can edit the patch as much as you like, including adding/removing
lines, editing the text, whatever. Make sure, though, that the first
character of the hunk lines is still a space, a plus or a minus.
After you closed the editor, Git will adjust the line counts of the hunks
if necessary, thanks to the --recount option of apply, and commit the
patch. Except if you deleted everything, in which case nothing happens
(for obvious reasons).

I told people on the kernel mailing list to please use "-M" when sending
me rename patches, so that I can see what they do while reading email
rather than having to apply the patch and then look at the end result.
I also told them that if they want to make it the default, they can just
add
[diff]
renames
to their ~/.gitconfig file. And while I was thinking about that, I wanted
to also check whether you can then mark individual projects to _not_ have
that default in the per-repository .git/config file.
And you can't. Currently you cannot have a global "enable renames by
default" and then a local ".. but not for _this_ project". Why? Because if
somebody writes
[diff]
renames = no
we simply ignore it, rather than resetting "diff_detect_rename_default"
back to zero.
Fixed thusly.

The --ignore-paths option to fetch is very useful for working on a subset
of a SVN repository. For proper operation, every command that causes a
fetch (explicit or implied) must include a matching --ignore-paths option.
This patch adds a persistent svn-remote.$repo_id.ignore-paths config by
promoting Fetcher::is_path_ignored to a member function and initializing
$self->{ignore_regex} in Fetcher::new. Command line --ignore-paths is
still recognized and acts in addition to the config value.

Btw, while doing this, I also though that "renames = on/off" made more

allow on/off.

This adds a row context menu command to compare this commit and its
descendants with the marked commit and its descendants. The results
are shown in the bottom-left pane. Commits are compared by checking
whether their headlines are the same and their patches have the same
patch ID as generated by git patch-id.
Merges are ignored and skipped over (as long as they have one
descendant). If two commits have the same patch ID then the process
will continue and compare their descendants, as long as they both have
exactly one descendant. If either commit has 0 or 2 or more descendants,
the comparison stops there. There is currently a limit of 100
comparisons.
This can be useful for checking whether one string of commits is just
a rebased version of another string of commits. Mark the end of one
string (i.e. the oldest commit in the string) and invoke "Compare with
marked commit" on the end of the other string.
As this is implemented, the UI will be unresponsive while the results
are being generated. This should be fixed.

For systems with a missing or broken perl, it is nicer to
explicitly say "we don't want perl" because:
1. The Makefile knows not to bother with Perl-ish things
like Git.pm.
2. We can print a more user-friendly error message
than "foo is not a git command" or whatever the broken
perl might barf
3. Test scripts that require perl can mark themselves and
such and be skipped
This patch implements parts (1) and (2). The perl/
subdirectory is skipped entirely, gitweb is not built, and
any git commands which rely on perl will print a
human-readable message and exit with an error code.
This patch is based on one from Robin H. Johnson.

This adds a context-menu command to put a mark on this commit. There
is at most one marked commit at any time, and it is indicated by a box
drawn around the headline. Once a commit is marked, two other
context-menu commands become available: one to select the marked commit,
and another to find the closest common descendant of this commit and
the marked commit.
The "find common descendant" command uses the displayed parent/child
relationships (i.e. the rewritten parent pointers produced by git log),
not the real parent/child relationships. Currently the UI will be
unresponsive while gitk is working out the nearest common descendant;
this should be improved in future.

Often we want to shorten a full ref name to something "prettier"
to show a user. For example, "refs/heads/master" is often shown
simply as "master", or "refs/remotes/origin/master" is shown as
"origin/master".
Many places in the code use a very simple formula: skip common
prefixes like refs/heads, refs/remotes, etc. This is codified in
the prettify_ref function.
for-each-ref has a more correct (but more expensive) approach:
consider the ref lookup rules, and try shortening as much as
possible while remaining unambiguous.
This patch makes the latter strategy globally available as
shorten_unambiguous_ref.
