There are basically two categories of update failures for
local refs:
1. problems outside of git, like disk full, bad
permissions, etc.
2. D/F conflicts on tracking branch ref names
In either case, there should already have been an error
message. In case '1', hopefully enough information has
already been given that the user can fix it. In the case of
'2', we can hint that the user can clean up their tracking
branch area by using 'git remote prune'.
Note that we don't actually know _which_ case we have, so
the user will receive the hint in case 1, as well. In this
case the suggestion won't do any good, but hopefully the
user is smart enough to figure out that it's just a hint.

This makes the default expiration period for the reflog that implements
stash infinite.
The original behaviour to autoexpire old stashes can be restored by using
the gc.refs/stash.{reflogexpire,reflogexpireunreachable} configration
variables introduced by the previous commit.

In addition to gc.reflogexpireunreachable and gc.reflogexpire, this lets
you set gc.<pattern>.reflogexpireunreachable and gc.<pattern>.reflogexpire
variables.
When "git reflog expire" expires reflog entry for $ref, the expiry timers
are taken from the first <pattern> that matches $ref (and if there isn't
the global default value is used).
For example, you could:
[gc "refs/stash"]
reflogexpire = never
reflogexpireunreachable = never
[gc "refs/remotes/*"]
reflogexpire = 7 days
reflogexpireunreachable = 3 days
[gc]
reflogexpire = 90 days
reflogexpireunreachable = 30 days

Commit ffe256f9ba ("git-svn: Speed up fetch")
introduced changes that create a temporary file for each object fetched by
svn. These files should be deleted automatically, but perl apparently
doesn't do this until the process exits (or perhaps when its garbage
collector runs).
This means that on a large fetch, especially with lots of branches, we
sometimes fill up /tmp completely, which prevents the next temp file from
being written completely. This is aggravated by the fact that a new temp
file is created for each updated file, even if that update produces a file
identical to one already in git. Thus, it can happen even if there's lots
of disk space to store the finished repository.
We weren't adequately checking for write errors, so this would result in an
invalid file getting committed, which caused git-svn to fail later with an
invalid checksum.
This patch adds a check to syswrite() so similar problems don't lead to
corruption in the future. It also unlink()'s each temp file explicitly
when we're done with it, so the disk doesn't need to fill up.

A lot of modules that have nothing to do with git-shell functionality
were linked in, bloating git-shell more than 8 times.
This patch cuts off redundant dependencies by:
1. providing stubs for three functions that make no sense for git-shell;
2. moving quote_path_fully from environment.c to quote.c to make the
later self sufficient;
3. moving make_absolute_path into a new separate file.

Before this patch, something like "git help tutorial" did not work,
people had to use "git help gittutorial" which is not very intuitive.
This patch uses the "is_git_command" function to test early if the
argument passed to "git help" is a git command, and if this is not the
case then we prefix the argument with "git" instead of "git-".
This way, things like "git help tutorial" or "git help glossary" will
work fine.
The little downside of this patch is that the "is_git_command" is a
little bit slow.

When working with a lot of people who backport patches all day long, every
once in a while I get a patch that modifies the same file more than once
inside the same patch. git-apply either fails if the second change relies
on the first change or silently drops the first change if the second change
is independent.
The silent part is the scary scenario for us. Also this behaviour is
different from the patch-utils.
I have modified git-apply to create a table of the filenames of files it
modifies such that if a later patch chunk modifies a file in the table it
will buffer the previously changed file instead of reading the original file
from disk.
Logic has been put in to handle creations/deletions/renames/copies. All the
relevant tests of git-apply succeed.
A new test has been added to cover the cases I addressed.
The fix is relatively straight-forward.

Previously, if there was an error while storing a local
tracking ref, the low-level functions would report an error,
but fetch's status output wouldn't indicate any problem.
E.g., imagine you have an old "refs/remotes/origin/foo/bar" but
upstream has deleted "foo/bar" in favor of a new branch
"foo". You would get output like this:
error: there are still refs under 'refs/remotes/origin/foo'
From $url_of_repo
* [new branch] foo -> origin/foo
With this patch, the output takes into account the status of
updating the local ref:
error: there are still refs under 'refs/remotes/origin/foo'
From $url_of_repo
! [new branch] foo -> origin/foo (unable to update local ref)

I'm working with a perforce repo using git-p4. There are some config
files which I need to change locally according to my environment. I'm
using a 'local' git branch to park these changes. And I want to avoid
accidentally checking them into p4 just by doing "git p4 submit"
mindlessly without realizing which branch I'm actually on.
This patch adds a new git config, 'git-p4.allowSubmit', which is a
whitelist of branch names. "git p4 submit" will only allow submissions
from local branches on the list. Useful for preventing inadvertently
submitting from a strictly local branch.
For backward compatibility, if this config is not set at all,

git help -a scans the PATH for git commands. On Windows it failed for two
reasons:
- The PATH separator is ';', not ':' on Windows.
- stat() does not set the executable bit.
We now open the file and guess whether it is executable.
The result of the guess is good enough for the list of git commands, but
it is of no use for a general stat() implementation because (1) it is a
guess, (2) the user has no way to influence the outcome (via chmod or
similar), and (3) it would reduce stat() performance by an unacceptable
amount. Therefore, this strategy is a special-case local to help.c.
