This patch changes git-pack-redundant so that packfiles
in alternate object directories also are considered when
deciding which objects are redundant.

This functionality is controlled by the flag '--alt-odb'.

Also convert the other flags to the long form, and update
docs and git-repack accordingly.

This patch renames git-pack-intersect to git-pack-redundant
as suggested by Petr Baudis. The new name reflects what the
program does, rather than how it does it.

Also fix a small argument parsing bug.

If two sides added the same path completely different thing, it is
easier to see the merge pivoting on /dev/null.  So check the size of
the common section we have found, and empty it if it is too small.

This is a specialized hack to help no-base merges, but other
people might find it useful, so let's document it.

Unlike the previous round that merged the path added differently
in each branches using emptiness as the base, compute a common
version and use it as input to 'merge' program.

This would show the resulting (still conflicting) file left in
the working tree as:

	common file contents...
	<<<<<< FILENAME
	version from our branch...
	======
	version from their branch...
	>>>>>> .merge_file_XXXXXX
	more common file contents...

when both sides added similar contents.

Instead of leaving the path unmerged in a case where each side
adds different version of the same path, attempt to merge it
with empty base and leave "our" version in the index file, just
like we do for the case in conflicting merge.

Because a batch-oriented script creates many commits within a second
on a fast machine, show-branch output of the test results are unstable
without topo-order.
Signed-off-by: NJunio C Hamano <junkio@cox.net>

With the change in the previous round, we are guaranteed to come up
with the list of all relevant merge bases, but sometimes we do not
fully mark unintersting ones due to a horizon effect.  Add a phase to
postprocess, so that we mark all ancestor of "interesting" commit.

This also changes the default ordering of shown commits back to
chronological order, and adds --topo-order flag to show them in
topological order.
Signed-off-by: NJunio C Hamano <junkio@cox.net>

This makes the merge-base computation resistant to the pathological
case discussed on the list earlier, by doing the same logic as
git-merge-base.  As a side effect, it breaks the command's primary
function to list non-merge commit sequences, which needs to be fixed
separately.

Although it was shown that the "full contamination" was not really full

When we have only one merge-base candidates in the result list,
there is no point going back to mark the reachable commits
again.  And that is the most common case, so try not to waste
time on it.  Suggested by Linus.

Some specfile cleanups after the split.
- zlib dependency fix, current method is inconsistent, you can
  potentially build a package that you can't install on machine you
  built it on
- Add proper defattr
- Remove trailing '.' in summary

- Add git-core dependency for each subpackage
- Move arch import to separate package as well

Arch uses pika escaping in some places (but not all!). Specifically, commits of
the type 'patch' use pika escaping in the log entries, which we parse to know
what to add/delete and what to commit.

This patch checks for hints of pika escaping and asks tla to unescape for us.

When doing an octopus, we incorrectly used the previous merge
base as the reference to compute next merge base.  This was
unnecessary, because that can never be better than using the
original HEAD.  And that is far simpler as well ;-).

I noticed format-patch loses authorship information of Lukas' patch
when I run git tools with LC_LANG set to ja_JP.  It turns out that
the sed script to set environment variables were not working on his
name (encoded in UTF-8), which is unfortunate but technically correct.

Force sed invocation under C locale because we always want literal byte
semantics.

This does two things:

 - It changes the hardcoded default merge strategy for two-head
   git-pull from resolve to recursive.

 - .git/config file acquires two configuration items.
   pull.twohead names the strategy for two-head case, and
   pull.octopus names the strategy for octopus merge.

IOW you are paranoid, you can have the following lines in your
.git/config file and keep using git-merge-resolve when pulling
one remote:

	[pull]
		twohead = resolve

OTOH, you can say this:

	[pull]
		twohead = resolve
		twohead = recursive

to try quicker resolve first, and when it fails, fall back to
recursive.
