If committing a merge (.git/MERGE_HEAD exists), an initial tree
(no HEAD) or using --amend to amend the prior commit then denote
the subtype of commit in the reflog. This helps to distinguish
amended or merge commits from normal commits.
In the case of --amend the prior sha1 is probably the commit which
is being thrown away in favor of the new commit. Since it is likely
that the old commit doesn't have any ref pointing to it anymore
it can be interesting to know why that the commit was replaced
and orphaned.
In the case of a merge the prior sha1 is probably the first parent
of the new merge commit. Consequently having its prior sha1 in the
reflog is slightly less interesting but its still informative to
know the commit was the result of a merge which had to be completed
by hand.

The current behaviour strips out lines starting with a # even when fed
through stdin or -m. This is particularly bad when importing history from
another SCM (tailor 0.9.23 uses git-commit). In the best cases all lines
are stripped and the commit fails with a confusing "empty log message"
error, but in many cases the commit is done, with loss of information.
Note that it is quite peculiar to just have "#" handled as a leading
comment char here. One commonly meet CVS: or CG: or STG: as prefixes, and
using GIT: would be more robust as well as consistent with other commit
tools. However, that would break any tool relying on the # (if any).

Some people tend to do many little commits on a topic branch,
recording all the trials and errors, and when the topic is
reasonably cooked well, would want to record the net effect of
the series as one commit on top of the mainline, removing the
cruft from the history. The topic is then abandoned or forked
off again from that point at the mainline.
The barebone porcelainish that comes with core git tools does
not officially support such operation, but you can fake it by
using "git pull --no-merge" when such a topic branch is not a
strict superset of the mainline, like this:
git checkout mainline
git pull --no-commit . that-topic-branch
: fix conflicts if any
rm -f .git/MERGE_HEAD
git commit -a -m 'consolidated commit log message'
git branch -f that-topic-branch ;# now fully merged
This however does not work when the topic branch is a fast
forward of the mainline, because normal "git pull" will never
create a merge commit in such a case, and there is nothing
special --no-commit could do to begin with.
This patch introduces a new option, --squash, to support such a
workflow officially in both fast-forward case and true merge
case. The user-level operation would be the same in both cases:
git checkout mainline
git pull --squash . that-topic-branch
: fix conflicts if any -- naturally, there would be
: no conflict if fast forward.
git commit -a -m 'consolidated commit log message'
git branch -f that-topic-branch ;# now fully merged
When the current branch is already up-to-date with respect to
the other branch, there truly is nothing to do, so the new
option does not have any effect.
This was brought up in #git IRC channel recently.

Spotted by Linus and Darrin Thompson. When we took a commit

We still need the "do we have anything to commit?" check by

The new flag is used to amend the tip of the current branch. Prepare
the tree object you would want to replace the latest commit as usual
(this includes the usual -i/-o and explicit paths), and the commit log
editor is seeded with the commit message from the tip of the current
branch. The commit you create replaces the current tip -- if it was a
merge, it will have the parents of the current tip as parents -- so the
current top commit is discarded.
It is a rough equivalent for:
$ git reset --soft HEAD^
$ ... do something else to come up with the right tree ...
$ git commit -c ORIG_HEAD
but can be used to amend a merge commit.

This revamps the git-status command to take the same set of
parameters as git commit. It gives a preview of what is being
committed with that command. With -v flag, it shows the diff
output between the HEAD commit and the index that would be
committed if these flags were given to git-commit command.
git-commit also acquires -v flag (it used to mean "verify" but
that is the default anyway and there is --no-verify to turn it
off, so not much is lost), which uses the updated git-status -v
to seed the commit log buffer. This is handy for writing a log
message while reviewing the changes one last time.
Now, git-commit and git-status are internally share the same
implementation.
Unlike previous git-commit change, this uses a temporary index
to prepare the index file that would become the real index file
after a successful commit, and moves it to the real index file
once the commit is actually made. This makes it safer than the
previous scheme, which stashed away the original index file and
restored it after an aborted commit.

Introduce --only flag to allow the new "partial commit"
semantics when paths are specified. The default is still the
traditional --include semantics. Once peoples' fingers and
scripts that want the traditional behaviour are updated to
explicitly say --include, we could change it to either default
to --only, or refuse to operate without either --only/--include
when paths are specified.
This also fixes a couple of bugs in the previous round. Namely:
- forgot to save/restore index in some cases.
- forgot to use the temporary index to show status when '--only
paths...' semantics was used.
- --author did not take precedence when reusing an existing
commit.

- "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>'

In a workflow that employs relatively long lived topic branches,

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

corresponding hand-resolve results on the initial manual merge,
and later by noticing the same conflicted automerge and applying

The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.
If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'. Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.
If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree. The user is asked to resolve them by hand and make a
commit manually.
The calling convention from the 'git merge' driver to merge
strategy programs is very simple:
- A strategy program is to be called 'git-merge-<strategy>'.
- They take input of this form:
<common1> <common2> ... '--' <head> <remote1> <remote2>...
That is, one or more the common ancestors, double dash, the
current head, and one or more remote heads being merged into
the current branch.
- Before a strategy program is called, the working tree is
matched to the current <head>.
- The strategy program exits with status code 0 when it
successfully auto-merges the given heads. It should do
update-cache for all the merged paths when it does so -- the
index file will be used to record the merge result as a
commit by the driver.
- The strategy program exits with status code 1 when it leaves
conflicts behind. It should do update-cache for all the
merged paths that it successfully auto-merged, and leave the
cache entry in the index file as the same as <head> for paths
it could not auto-merge, and leave its best-effort result
with conflict markers in the working tree when it does so.
- The strategy program exists with status code other than 0 or
1 if it does not handle the given merge at all.
As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.
