230a456638 rebase -i: teach --onto A...B syntax
When rewriting commits on a topic branch, sometimes it is easier to
compare the version of commits before and after the rewrite if they are
based on the same commit that forked from the upstream. An earlier commit
by Junio (fixed up by the previous commit) gives "--onto A...B" syntax to
rebase command, and rebases on top of the merge base between A and B;
teach the same to the interactive version, too.

e49ca974d6 rebase -i: abort cleanly if the editor fails to launch
If the user's configured editor is emacsclient, the editor
will fail to launch if emacs is not running and the git
command that tried to lanuch the editor will abort. For most
commands, all you have to do is to start emacs and repeat
the command.

The "git rebase -i" command, however, aborts without cleaning
the "$GIT_DIR/rebase-merge" directory if it fails to launch the
editor, so you'll need to do "git rebase --abort" before
repeating the rebase command.

Change "git rebase -i" to terminate using "die_abort" (instead of
with "die") if the initial launch of the editor fails.

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.

f1be316ada rebase -i: more graceful handling of invalid commands
Currently, when there is an invalid command, the rest of the line is
still treated as if the command had been valid, i.e. rebase -i attempts
to produce a patch, using the next argument as a SHA1 name. If there is
no next argument or an invalid one, very confusing error messages
appear (the line was '.'; path to git-rebase-todo substituted):

Unknown command: .
fatal: ambiguous argument 'Please fix this in the file $somefile.':
unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
fatal: Not a valid object name Please fix this in the file $somefile.
fatal: bad revision 'Please fix this in the file $somefile.'

Instead, verify the validity of the remaining line and error out earlier
if necessary.

1830d9cb62 Fix rebase -p --onto
In a rebase with --onto, the correct test for whether we can skip
rewriting a commit is if it is already on top of $ONTO, not $UPSTREAM.
Without --onto, this distinction does not exist and the behavior does
not change.

In a situation with two merged branches on a common base X:

 X---o---o---o---M
  \             /
   x---x---x---x

 Y

if we try to move the branches from their base on X to be based on Y,
so as to get

 X

 Y---o'--o'--o'--M'
  \             /
   x'--x'--x'--x'

then we fail.  The command `git rebase -p --onto Y X M` moves only the
first-parent chain, like so:

 X
  \
   x---x---x---x
                \
 Y---o'--o'--o'--M'

because it mistakenly drops the other branch(es) x---x---x---x from
the TODO file.  This tests and fixes this behavior.

Actually, I think the issue is pretty independent of submodules; when

So avoid passing an empty parameter to "git commit".

Actually, this is a nice cleanup, as MSG_FILE and EDIT_COMMIT were mutually
exclusive; use one variable instead

d911d1465d rebase -i: learn to rebase root commit
Teach git-rebase -i a new option --root, which instructs it to rebase
the entire history leading up to <branch>.  This is mainly for
symmetry with ordinary git-rebase; it cannot be used to edit the root
commit in-place (it requires --onto <newbase>).  Commits that already
exist in <newbase> are skipped.

In the normal mode of operation, this is fairly straightforward.  We
run cherry-pick in a loop, and cherry-pick has supported picking the
root commit since f95ebf7 (Allow cherry-picking root commits,
2008-07-04).

In --preserve-merges mode, we track the mapping from old to rewritten
commits and use it to update the parent list of each commit.  In this
case, we define 'rebase -i -p --root --onto $onto $branch' to rewrite
the parent list of all root commit(s) on $branch to contain $onto
instead.

e249044c67 rebase-i-p: minimum fix to obvious issues
Jeff King noticed that this series uses non-portable ${var:0:7} syntax
to splice a string, which is not even in POSIX, in the script.  A quick
look at around the offending part revealed a few issues, which this commit
fixes:

 * Why filter output from "rev-list --left-right A...B" and look for the
   ones that begin with ">"?  Wouldn't "rev-list A..B" give that?

 * The abbreviated SHA-1 are made with "rev-list --abbrev=7" into $TODO in
   an earlier invocation, and it can be more than 7 letters to avoid
   ambiguity.  Not just that "${r:0:7} is not even in POSIX", but use of
   it here is actively wrong.

 * There is no point in catting a single file and piping it into grep.

This seems like the best guess we can make until git sequencer marks are

d80d6bc146 rebase-i-p: do not include non-first-parent commits touching UPSTREAM
This covers an odd boundary case found by Avi Kivity's script where a branch
coming off of UPSTREAM is merged into HEAD. Initially it show up in
UPSTREAM..HEAD, but technically UPSTREAM is not moving, the rest of head is, so
we should not need to rewrite the merge.

This adds a check saying we can keep `preserve=t` if `p=UPSTREAM`...unless this
is the first first-parent commit in our UPSTREAM..HEAD rev-list, which could
very well point to UPSTREAM, but we still need to consider it as rewritten so we
start pulling in the rest of the UPSTREAM..HEAD commits that point to it.

faae853ca6 rebase--interactive: fix parent rewriting for dropped commits
`rebase -i -p` got its rev-list of commits to keep by --left-right and
--cherry-pick. Adding --cherry-pick would drop commits that duplicated changes
already in the rebase target.

The dropped commits were then forgotten about when it came to rewriting the
parents of their descendents, so the descendents would get cherry-picked with
their old, unwritten parents and essentially make the rebase a no-op.

This commit adds a $DOTEST/dropped directory to remember dropped commits and
rewrite their children's parent as the dropped commit's possibly-rewritten
first-parent.

ff74126c03 rebase -i: do not fail when there is no commit to cherry-pick
In case there is no commit to apply (for example because you rebase to
upstream and all your local patches have been applied there), do not
fail.  The non-interactive rebase already behaves that way.

Do this by introducing a new command, "noop", which is substituted for
an empty commit list, so that deleting the commit list can still abort
as before.

It is sometimes desirable to disable the safety net of pre-rebase hook

c14c3c82da git-rebase--interactive: auto amend only edited commit
"git rebase --continue" issued after git rebase being stop by "edit"
command is trying to amend the last commit using stage changes. However,
if the last commit is not the commit that was marked as "edit" then it
can produce unexpected results.

For instance, after being stop by "edit", I have made some changes to
commit message using "git commit --amend". After that I realized that
I forgot to add some changes to some file. So, I said "git add file"
and the "git rebase --continue". Unfortunately, it caused that the new
commit message was lost.

Another problem is that after being stopped at "edit", the user adds new
commits. In this case, automatic amend behavior of git rebase triggered
by some stage changes causes that not only that the log message of the
last commit is lost but that it will contain also wrong Author and Date
information.

Therefore, this patch restrict automatic amend only to the situation
where HEAD is the commit at which git rebase stop by "edit" command.

8beb1f33d1 git-rebase-interactive: do not squash commits on abort
If git rebase interactive is stopped by "edit" command and then the user
said "git rebase --continue" while having some stage changes, git rebase
interactive is trying to amend the last commit by doing:
  git --soft reset && git commit

However, the user can abort commit for some reason by providing an empty
log message, and that would leave the last commit undone, while the user
being completely unaware about what happened. Now if the user tries to
continue, by issuing "git rebase --continue" that squashes two previous
commits.

a8ccc204c5 rebase -i: When an 'edit' stops, mention the commit
In a rebase session where more than one commit is to be 'edit'ed, and the
user spends considerable time to 'edit' a commit, it is easy to forget what
one wanted to 'edit' at the individual commits. It would be helpful to see
at which commit the rebase stopped.

Incidentally, if the rebase stopped due to merge conflicts or other errors,
the commit was already reported ("Could not apply $sha1..."), but when
rebase stopped after successfully applying an "edit" commit, it would not
mention it. With this change the commit is reported.

1c5fa0a179 rebase-i: keep old parents when preserving merges
When "rebase -i -p" tries to preserve merges of unrelated branches, it
lost some parents:

 - When you have more than two parents, the commit in the new history
   ends up with fewer than expected number of parents and this breakage
   goes unnoticed;

 - When you are rebasing a merge with two parents and one is lost, the
   command tries to cherry-pick the original merge commit, and the command
   fails.

"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
-m" was by Brian Gernhardt; this extends on his idea.

aadbe44f88 grep portability fix: don't use "-e" or "-q"
System V versions of grep (such as Solaris /usr/bin/grep)
don't understand either of these options. git's usage of
"grep -e pattern" fell into one of two categories:

 1. equivalent to "grep pattern". -e is only useful here if
    the pattern begins with a "-", but all of the patterns
    are hardcoded and do not begin with a dash.

 2. stripping comments and blank lines with

      grep -v -e "^$" -e "^#"

    We can fortunately do this in the affirmative as

      grep '^[^#]'

Uses of "-q" can be replaced with redirection to /dev/null.
In many tests, however, "grep -q" is used as "if this string
is in the expected output, we are OK". In this case, it is
fine to just remove the "-q" entirely; it simply makes the
"verbose" mode of the test slightly more verbose.

f91333d646 git-rebase--interactive.sh: Make 3-way merge strategies work for -p.
git-rebase--interactive.sh used to pass all parents of a merge commit to
git-merge, which means that we have at least 3 heads to merge: HEAD,
first parent and second parent. So 3-way merge strategies like recursive
wouldn't work.

Fortunately, we have checked out the first parent right before the merge
anyway, so that is HEAD. Therefore we can drop simply it from the list
of parents, making 3-way strategies work for merge commits with only
two parents.

2a9c53e03d git-rebase--interactive.sh: Don't pass a strategy to git-cherry-pick.
git-cherry-pick doesn't support a strategy paramter, so don't pass one.
This means that --strategy for interactive rebases is a no-op for
anything but merge commits, but that's still better than being broken. A
correct fix would probably need to port the --merge behaviour from plain
git-rebase.sh, but I have no clue how to integrate that cleanly.

376ccb8cbb rebase -i: style fixes and minor cleanups
This patch indents ";;" consistently with the rest of git's shell scripts,
and makes sure that ";;" are before each "esac".

It introduces a helper function "has_action", to make it easier to read
the intentions of the code.

Errors from "git rev-parse --verify" are no longer ignored.

Spaces are quoted using single quotes instead of a backslash, for
readability.

A "test $preserve=f" (missing spaces) was fixed; hashes are no longer
written to "$DOTEST"/rewritten/ unnecessarily.

We used to quote the message for a squash, only to have "echo" unquote it.
Now we use "printf" and do not need to quote to start with.

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.

f09c9b8c5f Teach rebase -i about --preserve-merges
The option "-p" (or long "--preserve-merges") makes it possible to
rebase side branches including merges, without straightening the
history.

Example:

           X
            \
         A---M---B
        /
---o---O---P---Q

When the current HEAD is "B", "git rebase -i -p --onto Q O" will yield

               X
                 \
---o---O---P---Q---A'---M'---B'

Note that this will

- _not_ touch X [*1*], it does

- _not_ work without the --interactive flag [*2*], it does

- _not_ guess the type of the merge, but blindly uses recursive or
  whatever strategy you provided with "-s <strategy>" for all merges it
  has to redo, and it does

- _not_ make use of the original merge commit via git-rerere.

*1*: only commits which reach a merge base between <upstream> and HEAD
     are reapplied. The others are kept as-are.

*2*: git-rebase without --interactive is inherently patch based (at
     least at the moment), and therefore merges cannot be preserved.

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
