Martin von Zweigbergk 7b37a7c620 rebase: remember verbose option
Currently, only interactive rebase remembers the value of the '-v'
flag from the initial invocation. Make non-interactive rebase also
remember it.

Martin von Zweigbergk 84df4560ed rebase: extract code for writing basic state
Extract the code for writing the state to rebase-apply/ or
rebase-merge/ when a rebase is initiated. This will make it easier to
later make both interactive and non-interactive rebase remember the
options used.

Note that non-interactive rebase stores the sha1 of the original head
in a file called orig-head, while interactive rebase stores it in a
file called head. Change this by writing to orig-head in both
cases. When reading, try to read from orig-head. If that fails, read
from head instead. This protects users who upgraded git while they had
an ongoing interactive rebase, while still making it possible to
remove the code that reads from head at some point in the future.

Martin von Zweigbergk 2959c28366 rebase: factor out sub command handling
Factor out the common parts of the handling of the sub commands
'--continue', '--skip' and '--abort'. The '--abort' handling can
handled completely in git-rebase.sh.

After this refactoring, the calls to git-rebase--am.sh,
git-rebase--merge.sh and git-rebase--interactive.sh will be better
aligned. There will only be one call to interactive rebase that will
shortcut the very last part of git-rebase.sh.

Martin von Zweigbergk 431b7e7818 rebase -i: align variable names
Rename variables HEAD and OLDHEAD to orig_head and HEADNAME to
head_name, which are the names used in git-rebase.sh. This prepares
for factoring out of the code that persists these variables during the
entire rebase process. Using the same variable names to mean the same
thing in both files also makes the code easier to read.

While at it, also remove the DOTEST variable and use the state_dir
variable that was inherited from git-rebase.sh instead.

Martin von Zweigbergk 6bb4e485cf rebase: align variable names
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.

Jonathan Nieder 960ac5ff99 rebase -i: clarify in-editor documentation of "exec"
The hints in the current "instruction sheet" template look like so:

 # Rebase 3f14246..a1d7e01 onto 3f14246
 #
 # Commands:
 #  p, pick = use commit
 #  r, reword = use commit, but edit the commit message
 #  e, edit = use commit, but stop for amending
 #  s, squash = use commit, but meld into previous commit
 #  f, fixup = like "squash", but discard this commit's log message
 #  x <cmd>, exec <cmd> = Run a shell command <cmd>, and stop if it fails
 #
 # If you remove a line here THAT COMMIT WILL BE LOST.
 # However, if you remove everything, the rebase will be aborted.
 #

This does not make it clear that the format of each line is

	<insn> <commit id> <explanatory text that will be printed>

but the reader will probably infer that from the automatically
generated pick examples above it.

What about the "exec" instruction?  By analogy, I might imagine that
the format of that line is "exec <command> <explanatory text>", and
the "x <cmd>" hint does not address that question (at first I read it
as taking an argument <cmd> that is the name of a shell).  Meanwhile,
the mention of <cmd> makes the hints harder to scan as a table.

So remove the <cmd> and add some words to remind the reader that
"exec" runs a command named by the rest of the line.  To make room, it
is left to the manpage to explain that that command is run using
$SHELL and that nonzero status from that command will pause the
rebase.

Wording from Junio.

Jeff King 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.

if they match multiple commits, and it can also apply them to commits

todo list.

as they are emitted, and to avoid emitting a fixup/squash commit if the
commit has already been marked as used.

Brandon Casey 2d6ca6ef55 git-rebase--interactive.sh: rework skip_unnecessary_picks
Commit cd035b1c introduced the exec command to interactive rebase.  In
doing so, it modified the way that skip_unnecessary_picks iterates through
the list of rebase commands so that it avoided collapsing multiple spaces
into a single space.  This is necessary for example if the argument to the
exec command contains a path with multiple spaces in it.

The way it did this was by reading each line of rebase commands into a
single variable, and then breaking the individual components out using
echo, sed, and cut.  It used the individual broken-out components for
decision making, and was still able to write the original line to the
output file from the variable it had saved it in.  But, since we only
really need to look at anything other than the first element of the line
when a 'pick' command is encountered, and even that is only necessary when
we are still searching for "unnecessary" picks, and since newer rebase
commands like 'exec' may not even require a sha1 field, let's make our read
statement parse its input into a "command" variable, and a "rest" variable,
and then only break out the sha1 from $rest, and call git-rev-parse, when
absolutely necessary.

I think this future proofs this subroutine, avoids calling git-rev-parse
unnecessarily, and possibly with bogus arguments, and still accomplishes
the goal of not mangling the $rest of the rebase command.

Matthieu Moy cd035b1cef rebase -i: add exec command to launch a shell command
The typical usage pattern would be to run a test (or simply a compilation
command) at given points in history.

The shell command is ran (from the worktree root), and the rebase is
stopped when the command fails, to give the user an opportunity to fix
the problem before continuing with "git rebase --continue".

This needs a little rework of skip_unnecessary_picks, which wasn't robust
enough to deal with lines like

  exec >"file    name with many spaces"

in the todolist. The new version extracts command, sha1 and rest from
each line, but outputs the line itself verbatim to avoid changing the
whitespace layout.

Brandon Casey 938791cd01 git-rebase--interactive.sh: use printf instead of echo to print commit message
On systems with an echo which defaults to the XSI-conformant behavior
(Solaris, or others using Ksh), echo will interpret certain backslashed
characters as control sequences.  This can cause a problem for interactive
rebase when it is used to rebase commits whose commit "subject" (the first
line) contains any of these backslashed sequences.  In this case, echo will
substitute the control sequence for the backslashed characters and either
the rebased commit message will differ from the original, or the rebase
process will fail.  Neither is desirable.

So work around this issue by replacing the echo statements used to print
out portions of the commit message, with printf.

Also, add a test to test for this breakage.

'record_in_rewritten', was hidden in the arm where we have to record a
new commit for the user.  This meant that it was never invoked in the
case where the user has already amended the commit by herself.

[The test is designed to exercise both arms of the 'if' in question.]

Furthermore, recording the stopped-sha (the SHA1 of the commit before
the editing) suffered from a cut&paste error from die_with_patch and
used the wrong variable, hence it never recorded anything.

Noticed by Junio.

Marc Branchaud 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.

Junio C Hamano 3fa7c3da37 work around an obnoxious bash "safety feature" on OpenBSD
Bash (4.0.24) on OpenBSD 4.6 refuses to run this snippet:

    $ cat gomi.sh
    #!/bin/sh
    one="/var/tmp/1 1"
    rm -f /var/tmp/1 "/var/tmp/1 1"
    echo hello >$one
    $ sh gomi.sh; ls /var/tmp/1*
    /var/tmp/1 1
    $ bash gomi.sh; ls /var/tmp/1*
    gomi.sh: line 4: $one: ambiguous redirect
    ls: /var/tmp/1*: No such file or directory

Every competent shell programmer knows that a <$word in redirection is not
subject to field splitting (POSIX.1 "2.7 Redirection" explicitly lists the
kind of expansion performed: "... the word that follows the redirection
operator shall be subjected to ...", and "Field Splitting" is not among
them).

Some clueless folks apparently decided that users need to be protected in
the name of "security", however.

Output from "git grep -e '> *\$' -- '*.sh'" indicates that rebase-i
suffers from this bogus "safety".  Work it around by surrounding the
variable reference with a dq pair.

Junio C Hamano 76c9c0db3d rebase -i: Export GIT_AUTHOR_* variables explicitly
There is no point doing self-assignments of these variables.  Instead,
just export them to the environment, but do so in a sub-shell, because

	VAR1=VAL1 VAR2=VAL2 ... command arg1 arg2...

does not mark the variables exported if command that is run
is a shell function, according to POSIX.1.

The callers of do_with_author do not rely on seeing the effect of any
shell variable assignments that may happen inside what was called through
this shell function (currently "output" is the only one), so running it in
the subshell doesn't have an adverse semantic effect.

Björn Gustavsson 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.

Junio C Hamano 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.

Greg Price 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.

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

Actually, this is a nice cleanup, as MSG_FILE and EDIT_COMMIT were mutually

Thomas Rast 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.

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 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.

Stephen Haberman 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.

Dmitry Potapov 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.

However, the user can abort commit for some reason by providing an empty

being completely unaware about what happened. Now if the user tries to
continue, by issuing "git rebase --continue" that squashes two previous

Incidentally, if the rebase stopped due to merge conflicts or other errors,

 - When you are rebasing a merge with two parents and one is lost, the

This teaches "am" and "rebase" (all forms --- the vanilla one that uses

Johannes Schindelin 6848d58c60 Ignore dirty submodule states during rebase and stash
When rebasing or stashing, chances are that you do not care about
dirty submodules, since they are not updated by those actions anyway.
So ignore the submodules' states.

Note: the submodule states -- as committed in the superproject --
will still be stashed and rebased, it is _just_ the state of the
submodule in the working tree which is ignored.

Jeff King b4ce54fc61 remove use of "tail -n 1" and "tail -1"
The "-n" syntax is not supported by System V versions of
tail (which prefer "tail -1"). Unfortunately "tail -1" is
not actually POSIX.  We had some of both forms in our
scripts.

Since neither form works everywhere, this patch replaces
both with the equivalent sed invocation:

  sed -ne '$p'

Jeff King 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.

Junio C Hamano 4e6738778b Squelch bogus progress output from git-rebase--interactive
The command repeats "Rebasing (1/1)" many times even when
there is only one task remaining, because mark_action_done() is
called to skip comment and empty lines in the TODO file.

This should fix it.

Junio C Hamano ab11903225 git-rebase -i: clean-up error check codepath.
After replaying a single change, the code performed a number of checks,
but some of them were for sanity checking, failures from which should
make the command abort, and others were checks to see if it should make
a new commit object.  Stringing them together with "&&" was wrong.

Junio C Hamano 8ad1065e58 git-rebase -i behaves better on commits with incomplete messages
The commit message template when squashing multiple commits is
prepared by concatenating the messages of existing commits
together.  If the messages from some of them end with incomplete
lines, this would result in a suboptimal message template.  Make
sure that we add a terminating LF after each commit message.

Shawn O. Pearce 03270628ed Reallow git-rebase --interactive --continue if commit is unnecessary
During git-rebase --interactive's --continue implementation we used
to silently restart the rebase if the user had made the commit
for us.  This is common if the user stops to edit a commit and
does so by amending it.  My recent change to watch git-commit's
exit status broke this behavior.

Thanks to Bernt Hansen for catching it in 1.5.4-rc1.

Shawn O. Pearce dbedf9729b Catch and handle git-commit failures in git-rebase --interactive
If git-commit fails for any reason then git-rebase needs to stop
and not plow through the rest of the series.  Its unlikely that
a future git-commit will succeed if the current attempt failed.

Shawn O. Pearce c5b09feb78 Avoid update hook during git-rebase --interactive
If we are rebasing changes that contain potential whitespace
errors that our .git/hooks/pre-commit hook looks for and fails
on then git-commit will fail to commit that change.  This causes
git-rebase--interactive to squash commits together, even though it
was not requested to do so by the todo file.

Passing --no-verify to git-commit makes git-rebase -i behave more
like git-rebase normally would in such conditions, providing more
consistent behavior between the different rebase implementations.

Wincent Colaiuta 804c7174c9 revert/cherry-pick: Allow overriding the help text by the calling Porcelain
A Porcelain command that uses cherry-pick or revert may make a commit
out of resolved index itself, in which case telling the user to commit
the result is not appropriate at all.  This allows GIT_CHERRY_PICK_HELP
environment variable to be set by the calling Porcelain in order to
override the built-in help text.

 in spirit]
