When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been
resolved, we need to record a new notes commit on the appropriate notes
ref with the resolved notes.
This patch implements 'git notes merge --commit' which the user should
run after resolving conflicts in the notes merge worktree. This command
finalizes the notes merge by recombining the partial notes tree from
part 1 with the now-resolved conflicts in the notes merge worktree in a
merge commit, and updating the appropriate ref to this merge commit.
In order to correctly finalize the merge, we need to keep track of three
things:
- The partial merge result from part 1, containing the auto-merged notes.
This is now stored into a ref called .git/NOTES_MERGE_PARTIAL.
- The unmerged notes. These are already stored in
.git/NOTES_MERGE_WORKTREE, thanks to part 1.
- The notes ref to be updated by the finalized merge result. This is now
stored in a symref called .git/NOTES_MERGE_REF.
In addition to "git notes merge --commit", which uses the above details
to create the finalized notes merge commit, this patch also implements
"git notes merge --reset", which aborts the ongoing notes merge by simply
removing the files/directory described above.
FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove
the information described above (.git/NOTES_MERGE_*) after the notes merge
have been successfully finalized.
The patch also contains documentation and testcases for the two new options.

- Ævar Arnfjörð Bjarmason: Fix nonsense sentence in --commit description
- Sverre Rabbelier: Rename --reset to --abort

Conflicts (that are to be resolved manually) are written into a special-
purpose working tree, located at .git/NOTES_MERGE_WORKTREE. Within this
directory, conflicting notes entries are stored (with conflict markers
produced by ll_merge()) using the SHA1 of the annotated object. The
.git/NOTES_MERGE_WORKTREE directory will only contain the _conflicting_
note entries. The non-conflicting note entries (aka. the partial merge
result) are stored in 'local_tree', and the SHA1 of the resulting commit
is written to 'result_sha1'. The return value from notes_merge() is -1.
The user is told to edit the files within the .git/NOTES_MERGE_WORKTREE
directory in order to resolve the conflicts.
The patch also contains documentation and testcases for the correct setup
of .git/NOTES_MERGE_WORKTREE.
The next part will recombine the partial notes merge result with the
resolved conflicts in .git/NOTES_MERGE_WORKTREE to produce the complete
merge result.

The new -s/--strategy command-line option to 'git notes merge' allow the user
to choose how notes merge conflicts should be resolved. There are four valid
strategies to choose from:
1. "manual" (the default): This will let the user manually resolve conflicts.
This option currently fails with an error message. It will be implemented
properly in future patches.
2. "ours": This automatically chooses the local version of a conflict, and
discards the remote version.
3. "theirs": This automatically chooses the remote version of a conflict, and
discards the local version.
4. "union": This automatically resolves the conflict by appending the remote
version to the local version.
The strategies are implemented using the combine_notes_* functions from the
notes.h API.
The patch also includes testcases verifying the correct implementation of
these strategies.

This continuation of the 'git notes merge' implementation teaches notes-merge
to properly do real merges between notes trees: Two diffs are performed, one
from $base to $remote, and another from $base to $local. The paths in each
diff are normalized to SHA1 object names. The two diffs are then consolidated
into a single list of change pairs to be evaluated. Each change pair consist
of:
- The annotated object's SHA1
- The $base SHA1 (i.e. the common ancestor notes for this object)
- The $local SHA1 (i.e. the current notes for this object)
- The $remote SHA1 (i.e. the to-be-merged notes for this object)
From the pair ($base -> $local, $base -> $remote), we can determine the merge
result using regular 3-way rules. If conflicts are encountered in this
process, we fail loudly and exit (conflict handling to be added in a future
patch), If we can complete the merge without conflicts, the resulting
notes tree is committed, and the current notes ref updated.
The patch includes added testcases verifying that we can successfully do real
conflict-less merges.

The combine_notes_fn functions uses a non-zero return value to indicate
failure. However, this return value was converted to a call to die()
in note_tree_insert().
Instead, propagate this return value out to add_note(), and return it
from there to enable the caller to handle errors appropriately.
Existing add_note() callers are updated to die() upon failure, thus
preserving the current behaviour. The only exceptions are copy_note()
and notes_cache_put() where we are able to propagate the add_note()
return value instead.

Commit c84de70 (excluded_1(): support exclude files in index -
2009-08-20) added support for excluded() where dtype can be NULL. It
was designed specifically for index matching because there was no
other way to extract dtype information from index. It did not support
wildcard matching (for example, "a*/" pattern would fail to match).
The code was probably misread when commit 108da0d (git add: Add the
"--ignore-missing" option for the dry run - 2010-07-10) was made
because DT_UNKNOWN happens to be zero (NULL) too.
Do not pass DT_UNKNOWN/NULL to excluded(), instead pass a pointer to a
variable that contains DT_UNKNOWN. The real dtype will be extracted
from worktree by excluded(), as expected.

This new boolean option can be used to override the default for "git

Until now you had to call "git submodule update" (without -N|--no-fetch
option) or something like "git submodule foreach git fetch" to fetch
new commits in populated submodules from their remote.
This could lead to "(commits not present)" messages in the output of
"git diff --submodule" (which is used by "git gui" and "gitk") after
fetching or pulling new commits in the superproject and is an obstacle for
implementing recursive checkout of submodules. Also "git submodule
update" cannot fetch changes when disconnected, so it was very easy to
forget to fetch the submodule changes before disconnecting only to
discover later that they are needed.
This patch adds the "--recurse-submodules" option to recursively fetch
each populated submodule from the url configured in the .git/config of the
submodule at the end of each "git fetch" or during "git pull" in the
superproject. The submodule paths are taken from the index.
The hidden option "--submodule-prefix" is added to "git fetch" to be able
to print out the full paths of nested submodules.

'-0800' in their ---/+++ lines (e.g. http://lwn.net/Articles/131729/).
Take this into account when searching for the start of the timezone

This does not actually affect the outcome of patching unless (1) a

Usually when applying a binary diff generated without
--binary, it will be rejected early, as we don't even have
the full sha1 of the pre- and post-images.
However, if the diff is generated with --full-index (but not
--binary), then we will actually try to apply it. If we have
the postimage blob, then we can take a shortcut and never
even look at the binary diff at all (e.g., this can happen
when rebasing changes within a repository).
If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and
complains to the user instead of segfaulting. We need to
keep the check at a low level so that the "shortcut" case
above continues to work.
We also add a test that demonstrates the segfault. While
we're at it, let's also explicitly test the shortcut case.

simply because a pack edge object used as a preferred base is corrupted.
Since preferred base objects are not strictly needed to produce a valid

Delta compression may well be attempted against other objects in the

Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant. The latter message was
introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).
Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.
So leave off the "strange error" messages.
The result should look something like this:
$ git push sf master
Counting objects: 21542, done.
Compressing objects: 100% (4179/4179), done.
fatal: Unable to create temporary file: Permission denied
error: pack-objects died of signal 13
error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'
$
Or in the "controlled exit" case (contrived example):
[...]
fatal: delta size changed
error: failed to push some refs to 'ssh://example.com/foo/bar'
