David Kastrup 822f7c7349 Supplant the "while case ... break ;; esac" idiom
A lot of shell scripts contained stuff starting with

	while case "$#" in 0) break ;; esac

and similar.  I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance.  It
happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant.  In most cases, this has been
replaced by a straight condition using "test".  "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin.  Since none of them is likely to run the git
scripts, anyway, the added readability should be worth the change.

A few loops have had their termination condition expressed
differently.

Johannes Sixt 7afa845edc rebase -m: Fix incorrect short-logs of already applied commits.
When a topic branch is rebased, some of whose commits are already
cherry-picked upstream:

    o--X--A--B--Y    <- master
     \
      A--B--Z        <- topic

then 'git rebase -m master' would report:

    Already applied: 0001 Y
    Already applied: 0002 Y

With this fix it reports the expected:

    Already applied: 0001 A
    Already applied: 0002 B

As an added bonus, this change also avoids 'echo' of a commit message,
which might contain escapements.

Johannes Schindelin b4372ef136 Enable "git rerere" by the config variable rerere.enabled
Earlier, "git rerere" was enabled by creating the directory
.git/rr-cache.  That is definitely not in line with most other
features, which are enabled by a config variable.

So, check the config variable "rerere.enabled". If it is set
to "false" explicitely, do not activate rerere, even if
.git/rr-cache exists. This should help when you want to disable
rerere temporarily.

If "rerere.enabled" is not set at all, fall back to detection
of the directory .git/rr-cache.

Johannes Sixt 1308c17b3e Allow rebase to run if upstream is completely merged
Consider this history:

  o--o-...-B          <- origin
      \     \
       x--x--M--x--x  <- master

In this situation, rebase considers master fully up-to-date and would
not do anything. However, if there were additional commits on origin,
the rebase would run and move the commits x on top of origin.

Here we change rebase to short-circuit out only if the history since origin
is strictly linear. Consequently, the above as well as a history like this
would be linearized:

  o--o               <- origin
      \
       x--x
        \  \
         x--M--x--x  <- master

Johannes Schindelin 1b1dce4bae Teach rebase an interactive mode
Don't you just hate the fact sometimes, that git-rebase just applies
the patches, without any possibility to edit them, or rearrange them?
With "--interactive", git-rebase now lets you edit the list of patches,
so that you can reorder, edit and delete patches.

Such a list will typically look like this:

	pick deadbee The oneline of this commit
	pick fa1afe1 The oneline of the next commit
	...

By replacing the command "pick" with the command "edit", you can amend
that patch and/or its commit message, and by replacing it with "squash"
you can tell rebase to fold that patch into the patch before that.

It is derived from the script sent to the list in
<Pine.LNX.4.63.0702252156190.22628@wbgn013.biozentrum.uni-wuerzburg.de>

James Bowes fefe49d134 Add colour support in rebase and merge tree diff stats output.
The rebase and merge commands used diff-tree to display the summary stats of
what files had changed from the operation. diff-tree does not read the
diff ui configuration options, so the diff.color setting was not used.

Junio C Hamano a1bf91e081 git-rebase: make 'rebase HEAD branch' work as expected.
When you want to amend the commit message of 3 commits before
the tip of the current branch, say 'master',

	A--B--C--D--E(master)

it is sometimes handy to make your head detached at that commit
with:

	$ git checkout HEAD~3 ;# check out B
	$ git commit --amend ;# without modifying contents...

to create:

          .B'(HEAD)
         /
	A--B--C--D--E(master)

and then rebase 'master' branch onto HEAD with this:

	$ git rebase HEAD master

to result in:

          .B'-C'-D'-E(master=HEAD)
         /
	A--B--C--D--E

However, the current code interprets HEAD after it switches to
the branch 'master', which means the rebase will not do
anything.  You have to say something unwieldly like this
instead:

	$ git rebase $(git rev-parse HEAD) master

This fixes it by expanding the $onto commit name before
switching to the target branch.

This updates five commands (merge, pull, rebase, revert and cherry-pick)
so that they can be started from a subdirectory.

This may not actually be what we want to do.  These commands are
inherently whole-tree operations, and an inexperienced user may
mistakenly expect a "git pull" from a subdirectory would merge
only the subdirectory the command started from.

Shawn O. Pearce 7eff28a9b4 Disallow working directory commands in a bare repository.
If the user tries to run a porcelainish command which requires
a working directory in a bare repository they may get unexpected
results which are difficult to predict and may differ from command
to command.

Instead we should detect that the current repository is a bare
repository and refuse to run the command there, as there is no
working directory associated with it.

Shawn O. Pearce 0bb733c91c Use branch names in 'git-rebase -m' conflict hunks.
If a three-way merge in git-rebase generates a conflict then we
should take advantage of git-merge-recursive's ability to include
the branch name of each side of the conflict hunk by setting the
GITHEAD_* environment variables.

In the case of rebase there aren't really two clear branches; we
have the branch we are rebasing onto, and we have the branch we are
currently rebasing.  Since most conflicts will be arising between
the user's current branch and the branch they are rebasing onto
we assume the stuff that isn't in the current commit is the "onto"
branch and the stuff in the current commit is the "current" branch.

This assumption may however come up wrong if the user resolves one
conflict in such a way that it conflicts again on a future commit
also being rebased.  In this case the user's prior resolution will
appear to be in the "onto" part of the hunk.

Shawn O. Pearce f94741324e Use GIT_REFLOG_ACTION environment variable instead.
Junio rightly pointed out that the --reflog-action parameter
was starting to get out of control, as most porcelain code
needed to hand it to other porcelain and plumbing alike to
ensure the reflog contained the top-level user action and
not the lower-level actions it invoked.

At Junio's suggestion we are introducing the new set_reflog_action
function to all shell scripts, allowing them to declare early on
what their default reflog name should be, but this setting only
takes effect if the caller has not already set the GIT_REFLOG_ACTION
environment variable.

Junio C Hamano 228e2eb67e merge and reset: adjust for "reset --hard" messages
An earlier commit made "reset --hard" chattier but leaking its
message from "git rebase" (which calls it when first rewinding
the current branch to prepare replaying our own changes) without
explanation was confusing, so add an extra message to mention
it.  Inside restorestate in merge (which is rarely exercised
codepath, where more than one strategies are attempted),
resetting to the original state uses "reset --hard" -- this can
be squelched entirely.

Eric Wong f131dd492f rerere: record (or avoid misrecording) resolved, skipped or aborted rebase/am
Data in rr-cache isn't valid after a patch application is
skipped or and aborted, so our next commit could be misrecorded
as a resolution of that skipped/failed commit, which is wrong.

git-am --skip, git-rebase --skip/--abort will automatically
invoke git-rerere clear to avoid this.

Also, since git-am --resolved indicates a resolution was
succesful, remember to run git-rerere to record the resolution
(and not surprise the user when the next commit is made).

Johannes Schindelin 6d297f8137 Status update on merge-recursive in C
This is just an update for people being interested. Alex and me were
busy with that project for a few days now. While it has progressed nicely,
there are quite a couple TODOs in merge-recursive.c, just search for "TODO".

For impatient people: yes, it passes all the tests, and yes, according
to the evil test Alex did, it is faster than the Python script.

But no, it is not yet finished. Biggest points are:

- there are still three external calls
- in the end, it should not be necessary to write the index more than once
  (just before exiting)
- a lot of things can be refactored to make the code easier and shorter

BTW we cannot just plug in git-merge-tree yet, because git-merge-tree
does not handle renames at all.

This patch is meant for testing, and as such,

- it compile the program to git-merge-recur
- it adjusts the scripts and tests to use git-merge-recur instead of
  git-merge-recursive
- it provides "TEST", a script to execute the tests regarding -recursive
- it inlines the changes to read-cache.c (read_cache_from(), discard_cache()
  and refresh_cache_entry())

Junio C Hamano 5887ac821f rebase --merge: fix for rebasing more than 7 commits.
Instead of using 4-digit numbers to name commits being rebased,
just use "cmt.$msgnum" string, with $msgnum as a decimal number
without leading zero padding.  This makes it possible to rebase
more than 9999 commits, but of more practical importance is that
the earlier code used "printf" to format already formatted
$msgnum and barfed when it counted up to 0008.  In other words,
the old code was incapable of rebasing more than 7 commits, and
this fixes that problem.

Add "--continue" to restart the rebase process after
manually resolving conflicts.  The user is warned if
there are still differences between the index and the
working files.

Add "--abort" to restore the original branch, and
remove the .dotest working files.

Some minor additions to the git-rebase documentation.

[jc: fix that applies to the maintenance track has been dealt
 with separately.]
