git-rebase--interactive.sh will soon be sourced from
git-rebase.sh. Align the names of variables used in these scripts to
prepare for that.
Some names in git-rebase--interactive.sh, such as "author_script" and
"amend", are currently used in their upper case form to refer to a
file and in their lower case form to refer to something else. In these
cases, change the name of the existing lower case variable and
downcase the name of the variable that refers to the file.
Currently, git-rebase.sh uses mostly lower case variable names, while
git-rebase--interactive.sh uses mostly upper case variable names. For
consistency, downcase all variables, not just the ones that will be
shared between the two script files.

Detect early on if a rebase is in progress and what type of rebase it
is (interactive, merge-based or am-based). This prepares for further
refactoring where am-based rebase will be dispatched to
git-rebase--am.sh and merge-based rebase will be dispatched to
git-rebase--merge.sh.
The idea is to use the same variables whether the type of rebase was
detected from rebase-apply/ or rebase-merge/ directories or from the
command line options. This will make the code more readable and will
later also make it easier to dispatch to the type-specific scripts.
Also show a consistent error message independent of the type of rebase
that was in progress and remove the obsolete wording about being in
the middle of a 'patch application', since that (an existing
"$GIT_DIR"/rebase-apply/applying) aborts 'git rebase' at an earlier
stage.

The 'onto_name' state used in 'git rebase --merge' is currently read
once for each commit that need to be applied. It doesn't change
between each iteration, however, so it should be moved out of the

The code reading the state saved in $merge_dir or $rebase_dir is
currently spread out in many places, making it harder to read and to
introduce additional state. Extract this code into one method that
reads the state. Only extract the code associated with the state that
is written when the rebase is initiated. Leave the state that changes
for each commmit, at least for now.
Currently, when resuming a merge-based rebase using --continue or
--skip, move_to_original_branch (via finish_rb_merge) will be called
without head_name and orig_head set. These variables are then lazily
read in move_to_original_branch if head_name is not set (together with
onto, which is unnecessarily read again). Change this by always
eagerly reading the state, for both am-based and merge-based rebase,
in the --continue and --skip cases. Note that this does not change the
behavior for am-based rebase, which read the state eagerly even before
this commit.
Reading the state eagerly means that part of the state will sometimes
be read unnecessarily. One example is when the rebase is continued,
but stops again at another merge conflict. Another example is when the
rebase is aborted. However, since both of these cases involve user
interaction, the delay is hopefully not noticeable. The
call_merge/continue_merge loop is not affected.

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.

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

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.

This is in spirit similar to "checkout A...B". To re-queue a new set of

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

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,
2007-12-19) fixed "rebase -i", but "rebase -m" shared the same issue.

The new option --rebasing is used internally for rebase to tell am that

Also the option at the same time stands for --binary, -3 and -k which

Earlier, "git rerere" was enabled by creating the directory

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

Consider this history:

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:

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

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.

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.

At Junio's suggestion we are introducing the new set_reflog_action

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())

more than 9999 commits, but of more practical importance is that
the earlier code used "printf" to format already formatted
