git-commit: revamp the git-commit semantics.
- "git commit" without _any_ parameter keeps the traditional
behaviour. It commits the current index.
We commit the whole index even when this form is run from a
subdirectory.
- "git commit --include paths..." (or "git commit -i paths...")
is equivalent to:
git update-index --remove paths...
git commit
- "git commit paths..." acquires a new semantics. This is an
incompatible change that needs user training, which I am
still a bit reluctant to swallow, but enough people seem to
have complained that it is confusing to them. It
1. refuses to run if $GIT_DIR/MERGE_HEAD exists, and reminds
trained git users that the traditional semantics now needs
-i flag.
2. refuses to run if named paths... are different in HEAD and
the index (ditto about reminding). Added paths are OK.
3. reads HEAD commit into a temporary index file.
4. updates named paths... from the working tree in this
temporary index.
5. does the same updates of the paths... from the working
tree to the real index.
6. makes a commit using the temporary index that has the
current HEAD as the parent, and updates the HEAD with this
new commit.
- "git commit --all" can run from a subdirectory, but it updates
the index with all the modified files and does a whole tree
commit.
- In all cases, when the command decides not to create a new
commit, the index is left as it was before the command is
run. This means that the two "git diff" in the following
sequence:
$ git diff
$ git commit -a
$ git diff
would show the same diff if you abort the commit process by
making the commit log message empty.
This commit also introduces much requested --author option.
$ git commit --author 'A U Thor <author@example.com>'

git-rerere: reuse recorded resolve.
In a workflow that employs relatively long lived topic branches,
the developer sometimes needs to resolve the same conflict over
and over again until the topic branches are done (either merged
to the "release" branch, or sent out and accepted upstream).
This commit introduces a new command, "git rerere", to help this
process by recording the conflicted automerge results and
corresponding hand-resolve results on the initial manual merge,
and later by noticing the same conflicted automerge and applying
the previously recorded hand resolution using three-way merge.

Earlier, we made --base-path to automatically forbid

the use of user-relative paths independently. The latter form
of the option can be used to restrict accesses to a part of each
user's home directory, similar to "public_html" some webservers
supports.
If we're invoked with --user-path=FOO option, then a URL of the
form git://~USER/PATH/... resolves to the path HOME/FOO/PATH/...,
where HOME is USER's home directory.

rev-list: stop when the file disappears
The one thing I've considered doing (I really should) is to add a "stop
when you don't find the file" option to "git-rev-list". This patch does
some of the work towards that: it removes the "parent" thing when the
file disappears, so a "git annotate" could do do something like
git-rev-list --remove-empty --parents HEAD -- "$filename"
and it would get a good graph that stops when the filename disappears
(it's not perfect though: it won't remove all the unintersting commits).
It also simplifies the logic of finding tree differences a bit, at the
cost of making it a tad less efficient.
The old logic was two-phase: it would first simplify _only_ merges tree as
it traversed the tree, and then simplify the linear parts of the remainder
independently. That was pretty optimal from an efficiency standpoint
because it avoids doing any comparisons that we can see are unnecessary,
but it made it much harder to understand than it really needed to be.
The new logic is a lot more straightforward, and compares the trees as it
traverses the graph (ie everything is a single phase). That makes it much
easier to stop graph traversal at any point where a file disappears.
As an example, let's say that you have a git repository that has had a
file called "A" some time in the past. That file gets renamed to B, and
then gets renamed back again to A. The old "git-rev-list" would show two
commits: the commit that renames B to A (because it changes A) _and_ as
its parent the commit that renames A to B (because it changes A).
With the new --remove-empty flag, git-rev-list will show just the commit
that renames B to A as the "root" commit, and stop traversal there
(because that's what you want for "annotate" - you want to stop there, and
for every "root" commit you then separately see if it really is a new
file, or if the paths history disappeared because it was renamed from some
other file).
With this patch, you should be able to basically do a "poor mans 'git
annotate'" with a fairly simple loop:
push("HEAD", "$filename")
while (revision,filename = pop()) {
for each i in $(git-rev-list --parents --remove-empty $revision -- "$filename")
pseudo-parents($i) = git-rev-list parents for that line
if (pseudo-parents($i) is non-empty) {
show diff of $i against pseudo-parents
continue
}
/* See if the _real_ parents of $i had a rename */
parent($i) = real-parent($i)
if (find-rename in $parent($i)->$i)
push $parent($i), "old-name"
}
which should be doable in perl or something (doing stacks in shell is just
too painful to be worth it, so I'm not going to do this).
Anybody want to try?

The one thing I've considered doing (I really should) is to add a "stop
when you don't find the file" option to "git-rev-list". This patch does
some of the work towards that: it removes the "parent" thing when the
file disappears, so a "git annotate" could do do something like
git-rev-list --remove-empty --parents HEAD -- "$filename"
and it would get a good graph that stops when the filename disappears
(it's not perfect though: it won't remove all the unintersting commits).
It also simplifies the logic of finding tree differences a bit, at the
cost of making it a tad less efficient.
The old logic was two-phase: it would first simplify _only_ merges tree as
it traversed the tree, and then simplify the linear parts of the remainder
independently. That was pretty optimal from an efficiency standpoint
because it avoids doing any comparisons that we can see are unnecessary,
but it made it much harder to understand than it really needed to be.
The new logic is a lot more straightforward, and compares the trees as it
traverses the graph (ie everything is a single phase). That makes it much
easier to stop graph traversal at any point where a file disappears.
As an example, let's say that you have a git repository that has had a
file called "A" some time in the past. That file gets renamed to B, and
then gets renamed back again to A. The old "git-rev-list" would show two
commits: the commit that renames B to A (because it changes A) _and_ as
its parent the commit that renames A to B (because it changes A).
With the new --remove-empty flag, git-rev-list will show just the commit
that renames B to A as the "root" commit, and stop traversal there
(because that's what you want for "annotate" - you want to stop there, and

diff-files: -c and --cc options.
This ports the "combined diff" to diff-files so that differences
to the working tree files since stage 2 and stage 3 are shown
the same way as combined diff output from diff-tree for the
merge commit would be shown if the current working tree files
are committed.

combine-diff: better hunk splitting.
It considered an otherwise unchanged line that had line removals
in front of it an interesting line, which caused hunks to have
one extra the trailing context line.

diff-tree --cc: squelch header generation on empty patch.
Earlier round showed the commit log header and "diff --combined"
header even for paths that had no interesting hunk under --cc
flag. Move the header display logic around to squelch them.
With this, a merge that does not have any interesting merges
will not be shown with --cc option, unless -m is used at the
same time.

combine-diff: extend --cc logic to Octopus.
Santi Bejar points out that a hunk that changes from all the
same common parents except one is uninteresting. The earlier
round marked changes from only one parent uninteresting, but
this also marks hunks that have the same change from all but one
parent uninteresting, which is a natural extension of the
original idea to Octopus merges.

combine-diff: minor output changes.
Remove extra whitespace between the change indicators and the
body text. That is more in line with the uncombined unified
diff output (pointed out by Santi Bejar).
When showing --cc, say so instead of saying just --combined.

Building on the previous '-c' (combined) option, '--cc' option
squelches the output further by omitting hunks that consist of
