69a636ad1a rebase: clearer names for directory variables
Instead of using the old variable name 'dotest' for
"$GIT_DIR"/rebase-merge and no variable for "$GIT_DIR"/rebase-apply,
introduce two variables 'merge_dir' and 'apply_dir' for these paths.

4ac5356c62 rebase: give a better error message for bogus branch
When you give a non-existent branch to git-rebase, it spits
out the usage. This can be confusing, since you may
understand the usage just fine, but simply have made a
mistake in the branch name.

Before:

  $ git rebase origin bogus
  Usage: git rebase ...

After:

  $ git rebase origin bogus
  fatal: no such branch: bogus
  Usage: git rebase ...

3b21a438c9 rebase: use explicit "--" with checkout
In the case of a ref/pathname conflict, checkout will
already do the right thing and checkout the ref. However,
for a non-existant ref, this has two advantages:

  1. If a file with that pathname exists, rebase will
     refresh the file from the index and then rebase the
     current branch instead of producing an error.

  2. If no such file exists, the error message using an
     explicit "--" is better:

       # before
       $ git rebase -i origin bogus
       error: pathspec 'bogus' did not match any file(s) known to git.
       Could not checkout bogus

       # after
       $ git rebase -i origin bogus
       fatal: invalid reference: bogus
       Could not checkout bogus

The problems seem to be trigger-able only through "git
rebase -i", as regular git-rebase checks the validity of the
branch parameter as a ref very early on. However, it doesn't
hurt to be defensive.

9474a029d5 rebase: only show stat if configured to true
If rebase.stat is set to true, a diffstat should be displayed. If it is
not set, it should default to false. However, if it is explicitly set to
false (or other value), a diffstat is still displayed, which is probably
not what most users would expect. Show diffstat only if it is set
to true.

92c62a3f4f Porcelain scripts: Rewrite cryptic "needs update" error message
Although Git interally has the facility to differentiate between
porcelain and plubmbing commands and appropriately print errors,
several shell scripts invoke plubming commands triggering cryptic
plumbing errors to be displayed on a porcelain interface. This patch
replaces the "needs update" message in git-pull and git-rebase, when
`git update-index` is run, with a more friendly message.

93ce190cd1 rebase: support -X to pass through strategy options
git-rebase calls out to merge strategies, but did not support merge
strategy options so far.  Add this, in the same style used in
git-merge.

Sadly we have to do the full quoting/eval dance here, since
merge-recursive supports the --subtree=<path> option which potentially
contains whitespace.

This patch does not cover git rebase -i, which does not call any merge
strategy directly except in --preserve-merges, and even then only for
merges.

25e9325040 Fix git rebase --continue to work with touched files
When performing a non-interactive rebase, sometimes
"git rebase --continue" will fail if an unmodified file is
touched in the working directory:

    You must edit all merge conflicts and then
    mark them as resolved using git add

This is caused by "git diff-files" reporting a difference
between the index and the filesystem:

    :100644 100644 d00491...... 000000...... M	file

The fix is to run "git update-index --refresh" before
"git diff-files" as is done in git-rebase--interactive.

840b3ca758 rebase: protect against diff.renames configuration
We currently do not disable diff.renames configuration while rebase
internally runs "format-patch" to feed "am -3".

The end user configuration for "diff" should not affect the result
produced by the higher level command that is related to "diff" only
because internally it is implemented in terms of it.

For that matter, I have a feeling that format-patch should not even look
at diff.renames, but we seem to have been doing this for a long time so
there is no easy way to fix this thinko.

In any case, here is a much straightforward fix for "rebase".

b499549401 Teach rebase the --no-ff option.
For git-rebase.sh, --no-ff is a synonym for --force-rebase.

For git-rebase--interactive.sh, --no-ff cherry-picks all the commits in
the rebased branch, instead of fast-forwarding over any unchanged commits.

--no-ff offers an alternative way to deal with reverted merges.  Instead of
"reverting the revert" you can use "rebase --no-ff" to recreate the branch
with entirely new commits (they're new because at the very least the
committer time is different).  This obviates the need to revert the
reversion, as you can re-merge the new topic branch directly.  Added an
addendum to revert-a-faulty-merge.txt describing the situation and how to
use --no-ff to handle it.

96e19488f1 rebase: invoke post-rewrite hook
We have to deal with two separate code paths: a normal rebase, which
actually goes through git-am; and rebase {-m|-s}.

The only small issue with both is that they need to remember the
original sha1 across a possible conflict resolution.  rebase -m
already puts this information in $dotest/current, and we just
introduce a similar file for git-am.

Note that in git-am, the hook really only runs when coming from
git-rebase: the code path that sets the $dotest/original-commit file
is guarded by a test for $dotest/rebasing.

e1622bfcba Protect scripted Porcelains from GREP_OPTIONS insanity
If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect.  For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.

The approach taken by this change to address this issue is to protect only
our own use of grep/egrep.  Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.

On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

61dfa1bb67 "rebase --onto A...B" replays history on the merge base between A and B
This is in spirit similar to "checkout A...B".  To re-queue a new set of
patches for a series that the original author prepared to apply on 'next'
on the same base as before, you would do something like this:

    $ git checkout next^0
    $ git am -s rerolled-series.mbox
    $ git rebase --onto next...jh/notes next

The first two commands recreates commits to be rebased as the original
author intended (i.e. applies directly on top of 'next'), and the rebase
command replays that history on top of the same commit the series being
replaced was built on (which is typically much older than the tip of
'next').

The quiet option is maintained when git-am or git-rebase fails to apply
a patch. This means subsequent --resolved, --continue, --skip, --abort
invocations will be quiet if the original invocation was quiet.

Drop a handful of >&2 redirection; the rest of the program sends all the

a9c3821ca2 git-rebase: Add --stat and --no-stat for producing diffstat on rebase
The behavior of --verbose is unchanged, but uses a different state
variable internally, so that the meaning of verbose output may be
expanded without affecting the diffstat. This is also reflected in
the documentation.

The configuration option rebase.stat works the same was as merg.stat,
but the default is currently false.

190f53232d rebase: learn to rebase root commit
Teach git-rebase a new option --root, which instructs it to rebase the
entire history leading up to <branch>.  This option must be used with
--onto <newbase>, and causes commits that already exist in <newbase>
to be skipped.  (Normal operation skips commits that already exist in
<upstream> instead.)

One possible use-case is with git-svn: suppose you start hacking
(perhaps offline) on a new project, but later notice you want to
commit this work to SVN.  You will have to rebase the entire history,
including the root commit, on a (possibly empty) commit coming from
git-svn, to establish a history connection.  This previously had to
be done by cherry-picking the root commit manually.

07e62b733f rebase: improve error messages about dirty state
If you have unstaged changes in your working tree and try to
rebase, you will get the cryptic "foo: needs update"
message, but nothing else.  If you have staged changes, you
get "your index is not up-to-date".

Let's improve this situation in two ways:

 - for unstaged changes, let's also tell them we are
   canceling the rebase, and why (in addition to the "needs
   update" lines)

 - for the staged changes case, let's use language that is a
   little more clear to the user: their index contains
   uncommitted changes

f8cca019b9 rebase: Support preserving merges in non-interactive mode
As a result of implementation details, 'git rebase' could
previously only preserve merges in interactive mode. That
limitation was hard for users to understand and awkward to
explain.

This patch works around it by running the interactive rebase
helper git-rebase--interactive with GIT_EDITOR set to ':'
when the user passes "-p" but not "-i" to the rebase command.
The effect is that the interactive rebase helper is used but
the user never sees an editor.

The test-case included in this patch was originally written
by Stephen Habermann <stephen@exigencecorp.com>, but has
been extensively modified since its creation.

If .git/rebase-merge or .git/rebase-apply/rebasing exists, git-rebase

If .git/rebase-apply/applying exists, git-rebase will die with a message
saying that git-am is in progress, regardless how many arguments are

If no arguments are given and .git/rebase-apply/ exists, but neither a

22e407951e Teach "am" and "rebase" to mark the original position with ORIG_HEAD
"merge" and "reset" leave the original point in history in ORIG_HEAD,
which makes it easy to go back to where you were before you inflict a
major damage to your history and realize that you do not like the result
at all.  These days with reflog, we technically do not need to use
ORIG_HEAD, but it is a handy way nevertheless.

This teaches "am" and "rebase" (all forms --- the vanilla one that uses
"am" as its backend, "-m" variant that cherry-picks, and "--interactive")
to do the same.

The original idea and a partial implementation to do this only for "rebase

0cb06644a5 rebase [--onto O] A B: omit needless checkout
This teaches "git rebase [--onto O] A B" to omit an unnecessary checkout
of branch B before it goes on.

"git-rebase" originally was about rebasing the current branch to somewhere
else, and when the extra parameter to name which branch to rebase was
added, it defined the semantics to the safest but stupid "first switch to
the named branch and then operate exactly the same way as if we were
already on that branch".

But the first thing the real part of "rebase" does is to reset the work
tree and the index to the "onto" commit.  Which means the "rebase that
branch" form switched the work tree to the tip of the branch only to
immediately switch again to another commit.  This was wasteful.

When rebasing changes that contain issues that the pre-commit hook flags
as problematic, the rebase cannot be continued.  However, rebase is about
transplanting commits that are already made with as little distortion as
possible, and pre-commit check should not interfere.

Earlier, c5b09fe (Avoid update hook during git-rebase --interactive,

A lot of shell scripts contained stuff starting with

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.

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

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

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
