Miklos Vajna 1c6669351a Fix t7601-merge-pull-config.sh on AIX
The test failed on AIX (and likely other OS, such as apparently OSX)
where wc -l outputs whitespace.

Also, avoid unnecessary eval in conflict_count().

Miklos Vajna f4022fa33f Add new test case to ensure git-merge reduces octopus parents when possible
The old shell version used show-branch --independent to filter for the
ones that cannot be reached from any other reference.

The new C version uses reduce_heads() from commit.c for this, so
add test to ensure it works as expected.

Junio C Hamano 98cf9c3bd7 Introduce reduce_heads()
The new function reduce_heads() is given a list of commits, and removes
ones that can be reached from other commits in the list.  It is useful for
reducing the commits randomly thrown at the git-merge command and remove
redundant commits that the user shouldn't have given to it.

The implementation uses the get_merge_bases_many() introduced in the
previous commit.  If the merge base between one commit taken from the list
and the remaining commits is the commit itself, that means the commit is
reachable from some of the other commits.

Junio C Hamano 6a938648e1 Introduce get_merge_bases_many()
This introduces a new function get_merge_bases_many() which is a natural
extension of two commit merge base computation.  It is given one commit
(one) and a set of other commits (twos), and computes the merge base of
one and a merge across other commits.

This is mostly useful to figure out the common ancestor when iterating
over heads during an octopus merge.  When making an octopus between
commits A, B, C and D, we first merge tree of A and B, and then try to
merge C with it.  If we were making pairwise merge, we would be recording
the tree resulting from the merge between A and B as a commit, say M, and
then the next round we will be computing the merge base between M and C.

         o---C...*
        /       .
       o---B...M
      /       .
     o---o---A

But during an octopus merge, we actually do not create a commit M.  In
order to figure out that the common ancestor to use for this merge,
instead of computing the merge base between C and M, we can call
merge_bases_many() with one set to C and twos containing A and B.

Avery Pennarun 29c70e0b3e git-svn: avoid filling up the disk with temp files.
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.

Dmitry Potapov 5b8e6f85f9 shrink git-shell by avoiding redundant dependencies
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.

The following numbers have been received with the default optimization
settings on master using GCC 4.1.2:

Christian Couder 2dce956e39 help: check early if we have a command, if not try a documentation topic
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.

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,
submissions from all branches are allowed.
