Good.
Duy's "do we want to chdir or stay?" would be an orthogonal axis to
"what does the command line look like?" and "how is the command line
run?" so it adds one member to the "alias.<string>.*" family of
variables, I guess.

I actually wrote it that way first (I called it "maybe_add_color()"),
but it felt a little funny to have a separate function that people might
be tempted to reuse (the right solution is generally to check
want_color() early as above, but we can't do that here because we have
to find the end of each placeholder).
What I have here is a little funny, too, though, as it keeps trying
other color names if it finds "red" but want_color() returns 0.

[administrivia: please don't top-post, it is extremely hard to
follow what is going on]
There indeed is a test that creates xfoo3 as a symbolic link and
leaves it in the filesystem pointing at xfoo2 much earlier in the
sequence. It seems that later one of the "add ignore-errors" tests
(there are two back-to-back) runs "git reset --hard" to make it (and
other symbolic links that are similarly named) go away, namely this
part of the code:
test_expect_success POSIXPERM,SANITY 'git add --ignore-errors' '
git reset --hard &&
date >foo1 &&
date >foo2 &&
chmod 0 foo2 &&
test_must_fail git add --verbose --ignore-errors . &&
git ls-files foo1 | grep foo1
'
rm -f foo2
test_expect_success POSIXPERM,SANITY 'git add (add.ignore-errors)' '
git config add.ignore-errors 1 &&
git reset --hard &&
date >foo1 &&
date >foo2 &&
chmod 0 foo2 &&
test_must_fail git add --verbose . &&
git ls-files foo1 | grep foo1
'
rm -f foo2
"git reset --hard" in the first one, because these symbolic links
are not in the index at that point in the sequence, would leave them
untracked and in the working tree. Then "add" is told to be
non-atomic with "--ignore-errors", adding them to the index while
reporting a failure. When the test after that runs "git reset --hard"
again, because these symlinks are in the index (and not in HEAD),
they are removed from the working tree.
And that is why normal people won't see xfoo3 in later tests, like
the one you had trouble with.
Are you running without SANITY by any chance (I am not saying that
you are doing a wrong thing--just trying to make sure I am guessing
along the correct route)?
If that is the issue, then I think the right correction would be to
make sure that the files that an individual test expects to be
missing from the file system is indeed missing by explicitly
removing it, perhaps like this.
I also notice that the problematic test uses "chmod 755"; don't we
need POSIXPERM prerequisite on this test, too, I wonder?
Thanks.

t3700: fix broken test under !SANITY
An "add --chmod=+x" test recently added by 610d55af0f ("add: modify
already added files when --chmod is given", 2016-09-14) used "xfoo3"
as a test file. The paths xfoo[1-3] were used by earlier tests for
symbolic links but they were expected to have been removed by the
test script reached this new test.
The removal with "git reset --hard" however happened in tests that
are protected by POSIXPERM,SANITY prerequisites. Platforms and test
environments that lacked these would have seen xfoo3 as a leftover
symbolic link, pointing somewhere else, and chmod test would have
given a wrong result.

* [PATCH v3 21/25] sequencer: remove overzealous assumption in rebase -i mode
From: Johannes Schindelin @ 2016-10-10 17:26 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
The sequencer was introduced to make the cherry-pick and revert
functionality available as library function, with the original idea
being to extend the sequencer to also implement the rebase -i
functionality.
The test to ensure that all of the commands in the script are identical
to the overall operation does not mesh well with that.
Therefore let's disable the test in rebase -i mode.
While at it, error out early if the "instruction sheet" (i.e. the todo
script) could not be parsed.

In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
The definition of this function goes back all the way to 043a449
(sequencer: factor code out of revert builtin, 2012-01-11), long before a
serious effort was made to translate all the error messages.
It is slightly out of the context of the current patch series (whose
purpose it is to re-implement the performance critical parts of the
interactive rebase in C) to make the error messages in the sequencer
translatable, but what the heck. We'll just do it while we're looking at
this part of the code.

In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
Quite a few error messages touched by this developer during the work to
speed up rebase -i started with an upper case letter, violating our
current conventions. Instead of sneaking in this fix (and forgetting
quite a few error messages), let's just have one wholesale patch fixing
all of the error messages in the sequencer.
While at it, the funny "error: Error wrapping up..." was changed to a
less funny, but more helpful, "error: failed to finalize...".
Pointed out by Junio Hamano.

* [PATCH v3 20/25] sequencer: refactor write_message()
From: Johannes Schindelin @ 2016-10-10 17:26 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
The write_message() function safely writes an strbuf to a file.
Sometimes it is inconvenient to require an strbuf, though: the text to
be written may not be stored in a strbuf, or the strbuf should not be
released after writing.
Let's refactor "safely writing string to a file" into
write_with_lock_file(), and make write_message() use it. The new
function makes it easy to create new convenience function
write_file_gently(); as some of the upcoming callers of this new
function would want to append a newline character, add a flag for it in
write_file_gently(), and thus in write_with_lock_file().
While at it, roll back the locked files in case of failure, as pointed
out by Hannes Sixt.

The return value of do_recursive_merge() may be positive (indicating merge
conflicts), or 0 (indicating success). It also may be negative, indicating
a fatal error that requires us to abort.
Now, if the return value indicates that there are merge conflicts, we
should not try to commit those changes, of course.

The run_git_commit() function already knows how to amend commits, and
with this new option, it can also clean up commit messages (i.e. strip
out commented lines). This is needed to implement rebase -i's 'fixup'
and 'squash' commands as sequencer commands.

To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
The subcommands are used exactly once, at the very beginning of
sequencer_pick_revisions(), to determine what to do. This is an
unnecessary level of indirection: we can simply call the correct
function to begin with. So let's do that.
While at it, ensure that the subcommands return an error code so that
they do not have to die() all over the place (bad practice for library
functions...).

* [PATCH v3 15/25] sequencer: allow editing the commit message on a case-by-case basis
From: Johannes Schindelin @ 2016-10-10 17:25 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
In the upcoming commits, we will implement more and more of rebase -i's
functionality inside the sequencer. One particular feature of the
commands to come is that some of them allow editing the commit message
while others don't, i.e. we cannot define in the replay_opts whether the
commit message should be edited or not.
Let's add a new parameter to the run_git_commit() function. Previously,
it was the duty of the caller to ensure that the opts->edit setting
indicates whether to let the user edit the commit message or not,
indicating that it is an "all or nothing" setting, i.e. that the
sequencer wants to let the user edit *all* commit message, or none at
all. In the upcoming rebase -i mode, it will depend on the particular
command that is currently executed, though.

* [PATCH v3 13/25] sequencer: prepare for rebase -i's commit functionality
From: Johannes Schindelin @ 2016-10-10 17:25 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
In interactive rebases, we commit a little bit differently than the
sequencer did so far: we heed the "author-script", the "message" and the
"amend" files in the .git/rebase-merge/ subdirectory.
Likewise, we may want to edit the commit message *even* when providing a
file containing the suggested commit message. Therefore we change the
code to not even provide a default message when we do not want any, and
to call the editor explicitly.
Also, in "interactive rebase" mode we want to skip reading the options
in the state directory of the cherry-pick/revert commands.
Finally, as interactive rebase's GPG settings are configured differently
from how cherry-pick (and therefore sequencer) handles them, we will
leave support for that to the next commit.

In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
As we are slowly teaching the sequencer to perform the hard work for
the interactive rebase, we need to read files that were written by
shell scripts.
These files typically contain a single line and are invariably ended
by a line feed (and possibly a carriage return before that). Let's use
a helper to read such files and to remove the line ending.

* [PATCH v3 12/25] sequencer: remember the onelines when parsing the todo file
From: Johannes Schindelin @ 2016-10-10 17:25 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
The `git-rebase-todo` file contains a list of commands. Most of those
commands have the form
<verb> <sha1> <oneline>
The <oneline> is displayed primarily for the user's convenience, as
rebase -i really interprets only the <verb> <sha1> part. However, there
are *some* places in interactive rebase where the <oneline> is used to
display messages, e.g. for reporting at which commit we stopped.
So let's just remember it when parsing the todo file; we keep a copy of
the entire todo file anyway (to write out the new `done` and
`git-rebase-todo` file just before processing each command), so all we
need to do is remember the begin offsets and lengths.
As we will have to parse and remember the command-line for `exec` commands
later, we do not call the field "oneline" but rather "arg" (and will reuse
that for exec's command-line).

* [PATCH v3 08/25] sequencer: strip CR from the todo script
From: Johannes Schindelin @ 2016-10-10 17:25 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
It is not unheard of that editors on Windows write CR/LF even if the
file originally had only LF. This is particularly awkward for exec lines
of a rebase -i todo sheet. Take for example the insn "exec echo": The
shell script parser splits at the LF and leaves the CR attached to
"echo", which leads to the unknown command "echo\r".
Work around that by stripping CR when reading the todo commands, as we
already do for LF.
This happens to fix t9903.14 and .15 in MSYS1 environments (with the
rebase--helper patches based on this patch series): the todo script
constructed in such a setup contains CR/LF thanks to MSYS1 runtime's
cleverness.
Based on a report and a patch by Johannes Sixt.

* [PATCH v3 06/25] sequencer: future-proof read_populate_todo()
From: Johannes Schindelin @ 2016-10-10 17:24 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
Over the next commits, we will work on improving the sequencer to the
point where it can process the todo script of an interactive rebase. To
that end, we will need to teach the sequencer to read interactive
rebase's todo file. In preparation, we consolidate all places where
that todo file is needed to call a function that we will later extend.

* [PATCH v3 07/25] sequencer: completely revamp the "todo" script parsing
From: Johannes Schindelin @ 2016-10-10 17:25 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
When we came up with the "sequencer" idea, we really wanted to have
kind of a plumbing equivalent of the interactive rebase. Hence the
choice of words: the "todo" script, a "pick", etc.
However, when it came time to implement the entire shebang, somehow this
idea got lost and the sequencer was used as working horse for
cherry-pick and revert instead. So as not to interfere with the
interactive rebase, it even uses a separate directory to store its
state.
Furthermore, it also is stupidly strict about the "todo" script it
accepts: while it parses commands in a way that was *designed* to be
similar to the interactive rebase, it then goes on to *error out* if the
commands disagree with the overall action (cherry-pick or revert).
Finally, the sequencer code chose to deviate from the interactive rebase
code insofar that when it comes to writing the file with the remaining
commands, it *reformats* the "todo" script instead of just writing the
part of the parsed script that were not yet processed. This is not only
unnecessary churn, but might well lose information that is valuable to
the user (i.e. comments after the commands).
Let's just bite the bullet and rewrite the entire parser; the code now
becomes not only more elegant: it allows us to go on and teach the
sequencer how to parse *true* "todo" scripts as used by the interactive
rebase itself. In a way, the sequencer is about to grow up to do its
older brother's job. Better.
In particular, we choose to maintain the list of commands in an array
instead of a linked list: this is flexible enough to allow us later on to
even implement rebase -i's reordering of fixup!/squash! commits very
easily (and with a very nice speed bonus, at least on Windows).
While at it, do not stop at the first problem, but list *all* of the
problems. This will help the user when the sequencer will do `rebase
-i`'s work by allowing to address all issues in one go rather than going
back and forth until the todo list is valid.

* [PATCH v3 05/25] sequencer: eventually release memory allocated for the option values
From: Johannes Schindelin @ 2016-10-10 17:24 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Jakub Narębski, Johannes Sixt
In-Reply-To: <cover.1476120229.git.johannes.schindelin@gmx.de>
The sequencer is our attempt to lib-ify cherry-pick. Yet it behaves
like a one-shot command when it reads its configuration: memory is
allocated and released only when the command exits.
This is kind of okay for git-cherry-pick, which *is* a one-shot
command. All the work to make the sequencer its work horse was
done to allow using the functionality as a library function, though,
including proper clean-up after use.
To remedy that, we now take custody of the option values in question,
requiring those values to be malloc()ed or strdup()ed (an alternative
approach, to add a list of pointers to malloc()ed data and to ask the
sequencer to release all of them in the end, was proposed earlier but
rejected during review).
Sadly, the current approach makes the code uglier, as we now have to
take care to strdup() the values passed via the command-line.
