The packfile portion of the "remove redundant" code
near the bottom of git-repack.sh is broken when
pack splitting occurs. Particularly since this is
the only place where we automatically delete packfiles,
make sure it works properly for all cases, old or new.

I've taught myself to use "git gc" instead of doing the repack explicitly,
but it doesn't actually do what I think it should do.
We've had packed refs for a long time now, and I think it just makes sense
to pack normal branches too. So I end up having to do
git pack-refs --all --prune
in order to get a nice git repo that doesn't have any unnecessary files.
So why not just do that in "git gc"? It's not as if there really is any
downside to packing branches, even if they end up changing later. Quite
often they don't, and even if they do, so what?
Also, make the default for refs packing just be an unambiguous "do it",
rather than "do it by default only for non-bare repositories". If you want
that behaviour, you can always just add a
[gc]
packrefs = notbare
in your ~/.gitconfig file, but I don't actually see why bare would be any
different (except for the broken reason that http-fetching used to be
totally broken, and not doing it just meant that it didn't even get
fixed in a timely manner!).
So here's a trivial patch to make "git gc" do a better job. Hmm?

In git.git repository, "git-name-rev v1.3.0~158" cannot name the
rev, while adjacent revs can be named.
This was because it gives up traversal from the tips of existing
refs as soon as it sees a commit that has older commit timestamp
than what is being named. This is usually a good heuristics,
but v1.3.0~158 has a slightly older commit timestamp than
v1.3.0~157 (i.e. it's child), as these two were made in a
separate repostiory (in fact, in a different continent).
This adds a hardcoded slop value (1 day) to the cut-off
heuristics to work this kind of problem around. The current
algorithm essentially runs around from the available tips down
to ancient commits and names every single rev available that are
newer than cut-off date, so a single day slop would not add that
much overhead in repositories with long enough history where the
performance of name-rev matters.
I think the algorithm could be made a bit smarter by deepening
the graph on demand as a new commit is asked to be named (this
would require rewriting of name_rev() function not to recurse
itself but use a traversal list like revision.c traverser does),
but that would be a separate issue.

Alberto Bertogli reported on #git that git-gui was exiting with
alt-q, while gitk on the same system was exiting with ctrl-q.
That was not what I wanted. I really wanted M1B to be bound to
the Control key on most non-Mac OS X platforms, but according to
Sam Vilain M1 on most systems means alt. Since gitk always does
control, I'm doing the same thing for all non-Mac OS X systems.

A few new configuration options grew out of the woodwork during the
1.5.2 series. Most of these are pretty easy to support a completion
of, so we do so.
I wanted to also add completion support for the <driver> part of
merge.<driver>.name but to do that we have to look at all of the
.gitattributes files and guess what the unique set of <driver>
strings would be. Since this appears to be non-trivial I'm punting
on it at this time.

(Somewhat) recently git-log learned about --reverse (to show commits
in the opposite order) and a looong time ago I think it learned
about --raw (to show the raw diff, rather than a unified diff).
These are both useful options, so we should make them easy for the
user to complete.

Recently the git-remote command grew an update subcommand, which
can be used to execute git-fetch across multiple repositories
in a single step. These can be configured with the 'remotes.*'
configuration options, so we can offer completion for any name that

This was just me being silly; I put the --not option into the

We've had completion for git-log for quite some time, but just
today I noticed we don't have it for the new builtin shortlog

When e8438420bb allowed us to reload
the marks table on subsequent runs of fast-import we really broke
things, as we set pack_id to MAX_PACK_ID for any objects we imported
into the marks table. Creating a branch from that mark should fail
as we attempt to read the object through a non-existant packed_git
pointer. Instead we have to use the normal Git object system to
locate the older commit, as we ourselves do not have a reference
to the packed_git it resides in.
This bug only occurred because t9300 was not complete enough.
When we added the --import-marks feature we didn't actually test
its implementation enough to verify the function worked as intended.
I have corrected that, and included the changes as part of this fix.
Prior versions of fast-import fail the new test(s); this commit
allows them to pass.
Credit for this bug find goes to Simon Hausmann <simon@lst.de> as
he recently identified a similiar bug in the tree lazy-loading path.

git-archive already knows how to generate an archive as a tar or a zip
file, but gitweb did not. zip archvies are much more usable in a Windows
environment due to native support and this patch allows a site admin the
option to deliver zip rather than tar files. The selection is done by
inserting

in gitweb_config.perl.
Tar files remain the default option.

The parser was inconsistently done, in that it did not look at
the last command line parameter to see if it could be an unknown
option, although it was designed to notice unknown options if
they were given in positions the command expects to find them

<commit-ish>). This prevented a very natural invocation

Often users want to know not which tagged version a commit came
after, but which tagged version a commit is contained within.
This latter task is the job of git-name-rev, but most users are
looking to git-describe to do the job.
Junio suggested we make `git describe --contains` run the correct
tool, `git name-rev`, and that's exactly what we do here. The output
of name-rev was adjusted slightly through the new --name-only option,
allowing describe to execv into name-rev and maintain its current
output format.
