When clang compiles sequencer.c, it complains:
sequencer.c:632:14: warning: comparison of constant 2 with
expression of type 'const enum todo_command' is always
true [-Wtautological-constant-out-of-range-compare]
if (command < ARRAY_SIZE(todo_command_strings))
This is because "command" is an enum that may only have two
values (0 and 1) and the array in question has two elements.
As it turns out, clang is actually wrong here, at least
according to its own bug tracker:
https://llvm.org/bugs/show_bug.cgi?id=16154
But it's still worth working around this, as the warning is
present with -Wall, meaning we fail compilation with "make
DEVELOPER=1".
Casting the enum to size_t sufficiently unconfuses clang. As
a bonus, it also catches any possible out-of-bounds access
if the enum takes on a negative value (which shouldn't
happen either, but again, this is a defensive check).

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...".

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.

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.

This commit prepares for future callers that will have a pointer/length
to some text to be written that lacks an LF, yet an LF is desired.
Instead of requiring the caller to append an LF to the buffer (and
potentially allocate memory to do so), the write_message() function
learns to append an LF at the end of the file.

Previously, we required an strbuf. But that limits the use case too much.
In the upcoming patch series (for which the current patch series prepares
the sequencer), we will want to write content to a file for which we have
a pointer and a length, not an strbuf.

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'

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.

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.

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.

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).

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...).

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.

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.

Not only does this DRY up the code (providing a better documentation what
the code is about, as well as allowing to change the behavior in a single
place), it also makes it substantially shorter to use the same

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

that todo file is needed to call a function that we will later extend.

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, take custody of the option values in question,
allocating and duping literal constants as needed and freeing them
at end.

This change is not completely faithful: instead of initializing all fields
to 0, we choose to initialize command and subcommand to -1 (instead of
defaulting to REPLAY_REVERT and REPLAY_NONE, respectively). Practically,
it makes no difference at all, but future-proofs the code to require
explicit assignments for both fields.

colon-separated format option suffix that might follow the field name.
However, it does so inside the loop, i.e. it performs the exact same
stripping over and over again.
Move stripping the format option suffix out of that loop, so it's only
performed once for each parsed field name.

We can replace strbuf_addf() calls that just add a simple string with
calls to strbuf_addstr() to make the intent clearer. We need to be
careful if that string contains printf format specifications like %%,
though, as a simple replacement would change the output.
Add checks to the semantic patch to make sure we only perform the
transformation if the second argument is a string constant (possibly
translated) that doesn't contain any percent signs.

columns, and then pads with spaces to graph->width by
calling graph_pad_horizontally(). However, we tell the
latter that we wrote graph->num_columns characters, which is
not true; we also needed spaces between the columns. Let's
keep a count of how many characters we've written, which is
what all the other callers of graph_pad_horizontally() do.
Without this, any output that is written at the end of a
padding line will be bumped out by at least an extra
graph->num_columns spaces. Presumably nobody ever noticed
the bug because there's no code path that actually writes to
the end of a padding line.

Almost everybody uses DEFAULT_ABBREV to refer to the default
setting for the abbreviation, but "git blame" peeked into
underlying variable bypassing the macro for no good reason.

This does not make any practical difference in today's code, but
everybody else accesses the default abbreviation length via the
DEFAULT_ABBREV macro. Make sure this oddball codepath does not
stray from the convention.

"git log rev^..rev" is an often-used revision range specification
to show what was done on a side branch merged at rev. This has
gained a short-hand "rev^-1". In general "rev^-$n" is the same as
"^rev^$n rev", i.e. what has happened on other branches while the
history leading to nth parent was looking the other way.

"git log rev^..rev" is commonly used to show all work done on and merged
from a side branch. This patch introduces a shorthand "rev^-" for this
and additionally allows "rev^-$n" to mean "reachable from rev, excluding
what is reachable from the nth parent of rev". For example, for a
two-parent merge, you can use rev^-2 to get the set of commits which were
made to the main branch while the topic branch was prepared.

When given an abbreviated object name that is not (or more
realistically, "no longer") unique, we gave a fatal error
"ambiguous argument". This error is now accompanied by hints that
lists the objects that begins with the given prefix. During the
course of development of this new feature, numerous minor bugs were
uncovered and corrected, the most notable one of which is that we
gave "short SHA1 xxxx is ambiguous." twice without good reason.

When we find ambiguous short sha1s, we may get a
disambiguation rule from our caller's context. But if we
don't, we fall back to treating all sha1s the same, even
though most projects will tend to refer only to commits by
their short sha1s.
This patch introduces a configuration option that lets the
user pick a different fallback (e.g., only commits). It's
possible that we may want to make this the default, but it's
a good idea to start as a config option for two reasons:
1. It lets people experiment with this and see if it's a
good idea (i.e., the "tend to" above is an assumption;
we don't really know if this will break some obscure
cases).
2. Even if we do flip the default, it gives people an
escape hatch if it causes problems (you can sometimes
override it by asking for "1234^{tree}", but not all
combinations are possible).

When the user gives us an ambiguous short sha1, we print an
error and refuse to resolve it. In some cases, the next step
is for them to feed us more characters (e.g., if they were
retyping or cut-and-pasting from a full sha1). But in other
cases, that might be all they have. For example, an old
commit message may have used a 7-character hex that was
unique at the time, but is now ambiguous. Git doesn't
provide any information about the ambiguous objects it
found, so it's hard for the user to find out which one they
probably meant.
This patch teaches get_short_sha1() to list the sha1s of the
objects it found, along with a few bits of information that
may help the user decide which one they meant. Here's what
it looks like on git.git:
$ git rev-parse b2e1
error: short SHA1 b2e1 is ambiguous
hint: The candidates are:
hint: b2e1196 tag v2.8.0-rc1
hint: b2e11d1 tree
hint: b2e1632 commit 2007-11-14 - Merge branch 'bs/maint-commit-options'
hint: b2e1759 blob
hint: b2e18954 blob
hint: b2e1895c blob
fatal: ambiguous argument 'b2e1': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
We show the tagname for tags, and the date and subject for
commits. For trees and blobs, in theory we could dig in the
history to find the paths at which they were present. But
that's very expensive (on the order of 30s for the kernel),
and it's not likely to be all that helpful. Most short
references are to commits, so the useful information is
typically going to be that the object in question _isn't_ a
commit. So it's silly to spend a lot of CPU preemptively
digging up the path; the user can do it themselves if they
really need to.
And of course it's somewhat ironic that we abbreviate the
sha1s in the disambiguation hint. But full sha1s would cause
annoying line wrapping for the commit lines, and presumably
the user is going to just re-issue their command immediately
with the corrected sha1.
We also restrict the list to those that match any
disambiguation hint. E.g.:
$ git rev-parse b2e1:foo
error: short SHA1 b2e1 is ambiguous
hint: The candidates are:
hint: b2e1196 tag v2.8.0-rc1
hint: b2e11d1 tree
hint: b2e1632 commit 2007-11-14 - Merge branch 'bs/maint-commit-options'
fatal: Invalid object name 'b2e1'.
does not bother reporting the blobs, because they cannot
work as a treeish.
