0f57f731ea Merge branch 'pw/sequencer-in-process-commit'
The sequencer infrastructure is shared across "git cherry-pick",
"git rebase -i", etc., and has always spawned "git commit" when it
needs to create a commit.  It has been taught to do so internally,
when able, by reusing the codepath "git commit" itself uses, which
gives performance boost for a few tens of percents in some sample
scenarios.

fbd7a23237 rebase: introduce and use pseudo-ref REBASE_HEAD
The new command `git rebase --show-current-patch` is useful for seeing
the commit related to the current rebase state. Some however may find
the "git show" command behind it too limiting. You may want to
increase context lines, do a diff that ignores whitespaces...

For these advanced use cases, the user can execute any command they
want with the new pseudo ref REBASE_HEAD.

This also helps show where the stopped commit is from, which is hard
to see from the previous patch which implements --show-current-patch.

66335298a4 rebase: add --show-current-patch
It is useful to see the full patch while resolving conflicts in a
rebase. The only way to do it now is

    less .git/rebase-*/patch

which could turn out to be a lot longer to type if you are in a
linked worktree, or not at top-dir. On top of that, an ordinary user
should not need to peek into .git directory. The new option is
provided to examine the patch.

ed1e52822e sequencer: assign only free()able strings to gpg_sign
The gpg_sign member of the replay_opts structure is of type `char *`,
meaning that the sequencer deems the string to which gpg_sign points to
be under its custody, i.e. it needs to be free()d by the sequencer.

Therefore, let's only assign malloc()ed buffers to it.

e4db47e6a0 Merge branch 'jk/rebase-i-exec-gitdir-fix'
A recent regression in "git rebase -i" that broke execution of git
commands from subdirectories via "exec" insn has been fixed.

09d7b6c6fa sequencer: pass absolute GIT_DIR to exec commands
When we replaced the old shell script based interactive rebase in
commmit 18633e1a22a6 ("rebase -i: use the rebase--helper builtin",
2017-02-09) we introduced a regression of functionality in that the
GIT_DIR would be sent to the environment of the exec command as-is.

This generally meant that it would be passed as "GIT_DIR=.git", which
causes problems for any exec command that wants to run git commands in
a subdirectory.

This isn't a very large regression, since it is not that likely that the
exec command will run a git command, and even less likely that it will
need to do so in a subdir. This regression was discovered by a build
system which uses git-describe to find the current version of the build
system, and happened to do so from the src/ sub directory of the
project.

Fix this by passing in the absolute path of the git directory into the
child environment.

47d4ac019b t3404: relax rebase.missingCommitsCheck tests
These tests were a bit anal about the *exact* warning/error message
printed by git rebase. But those messages are intended for the *end
user*, therefore it does not make sense to test so rigidly for the
*exact* wording.

In the following, we will reimplement the missing commits check in
the sequencer, with slightly different words.

So let's just test for the parts in the warning/error message that
we *really* care about, nothing more, nothing less.

0d75bfe67b tests: fix tests broken under GETTEXT_POISON=YesPlease
The GETTEXT_POISON=YesPlease compile-time testing option added in my
bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly
translator", 2011-02-22) has been slowly bitrotting as strings have
been marked for translation, and new tests have been added without
running it.

I brought this up on the list ("[BUG] test suite broken with
GETTEXT_POISON=YesPlease", [1]) asking whether this mode was useful at
all anymore. At least one person occasionally uses it, and Lars
Schneider offered to change one of the the Travis builds to run in
this mode, so fix up the failing ones.

My test setup runs most of the tests, with the notable exception of
skipping all the p4 tests, so it's possible that there's still some
lurking regressions I haven't fixed.

18633e1a22 rebase -i: use the rebase--helper builtin
Now that the sequencer learned to process a "normal" interactive rebase,
we use it. The original shell script is still used for "non-normal"
interactive rebases, i.e. when --root or --preserve-merges was passed.

Please note that the --root option (via the $squash_onto variable) needs
special handling only for the very first command, hence it is still okay
to use the helper upon continue/skip.

Also please note that the --no-ff setting is volatile, i.e. when the
interactive rebase is interrupted at any stage, there is no record of
it. Therefore, we have to pass it from the shell script to the
rebase--helper.

Note: the test t3404 had to be adjusted because the the error messages
produced by the sequencer comply with our current convention to start with
a lower-case letter.

b8fc9e43a7 i18n: rebase-interactive: mark here-doc strings for translation
Use pipe to send gettext output to git stripspace instead of the
original method of using shell here-document, because command
substitution '$(...)' would not take place inside the here-documents.
The exception is the case of the last here-document redirecting to cat,
in which commands substitution works and, thus, is preserved in this
commit.

t3404: adapt test to the strings newly marked for translation
Test t3404-rebase-interactive.sh would fail under GETTEXT_POISON unless
using test_i18ngrep.

Add eval_ngettext fallback functions to be called when running, for
instance, under GETTEXT_POISON. Otherwise, tests would fail under
GETTEXT_POISON, or other build that doesn't support the GNU gettext,
because that function could not be found.

7bec7f50ae t3404: use write_script
The test uses hardcoded #!/bin/sh to create a pre-commit hook
script.  Because the generated script uses $(command substitution),
which is not supported by /bin/sh on some platforms (e.g. Solaris),
the resulting pre-commit always fails.

Which is not noticeable as the test that uses the hook is about
checking the behaviour of the command when the hook fails ;-), but
nevertheless it is not testing what we wanted to test.

Use write_script so that the resulting script is run under the same
shell our scripted Porcelain commands are run, which must support
the necessary $(construct).

040fd39e67 rebase -i: remember merge options beyond continue actions
If the user explicitly specified a merge strategy or strategy
options, continue to use that strategy/option after
"rebase --continue".  Add a test of the corrected behavior.

If --merge is specified or implied by -s or -X, then "strategy and
"strategy_opts" are set to values from which "strategy_args" can be
derived; otherwise they are set to empty strings.  Either way,
their values are propagated from one step of an interactive rebase
to the next via state files.

"do_merge", on the other hand, is *not* propagated to later steps of
an interactive rebase.  Therefore, making the initialization of
"strategy_args" conditional on "do_merge" being set prevents later
steps of an interactive rebase from setting it correctly.

Luckily, we don't need the "do_merge" guard at all.  If the rebase
was started without --merge, then "strategy" and "strategy_opts"
are both the empty string, which results in "strategy_args" also
being set to the empty string, which is just what we want in that
situation.  So remove the "do_merge" guard and derive
"strategy_args" from "strategy" and "strategy_opts" every time.

39743cf554 rebase-i: work around Windows CRLF line endings
Editors on Windows can and do save text files with CRLF line
endings, which is the convention on the platform.  We are seeing
reports that the "read" command in a port of bash to the environment
however does not strip the CRLF at the end, not adjusting for the
same convention on the platform.

This breaks the recently added sanity checks for the insn sheet fed
to "rebase -i"; instead of an empty line (hence nothing in $command),
the script was getting a lone CR in there.

Special case a lone CR and treat it the same way as an empty line to
work this around.

This patch (also) passes the test with Git for Windows, where the
issue was seen first.

1db168ee97 rebase-i: loosen over-eager check_bad_cmd check
804098bb (git rebase -i: add static check for commands and SHA-1,
2015-06-29) tried to check all insns before running any in the todo
list, but it did so by implementing its own parser that is a lot
stricter than necessary.  We used to allow lines that are indented
(including comment lines), and we used to allow a whitespace between
the insn and the commit object name to be HT, among other things,
that are flagged as an invalid line by mistake.

Fix this by using the same tokenizer that is used to parse the todo
list file in the new check.

Whether it's a good thing to accept indented comments is
debatable (other commands like "git commit" do not accept them), but we
already accepted them in the past, and some people and scripts rely on
this behavior. Also, a line starting with space followed by a '#' cannot
have any meaning other than being a comment, hence it doesn't harm to
accept them as comments.

who do not use it (and instead just remove the lines) by throwing
a warning.

d0ab058498 tests: remove some direct access to .git/logs
Alternate refs backends might store reflogs somewhere other than
.git/logs.  Change most test code that directly accesses .git/logs to
instead use git reflog commands.

There are still a few tests which need direct access to reflogs: to
check reflog permissions, to manually create reflogs from scratch, to
save/restore reflogs, to check the format of raw reflog data, and to
remove not just reflog contents, but the reflogs themselves. All cases
which don't need direct access have been modified.

804098bb30 git rebase -i: add static check for commands and SHA-1
Check before the start of the rebasing if the commands exists, and for
the commands expecting a SHA-1, check if the SHA-1 is present and
corresponds to a commit. In case of error, print the error, stop git
rebase and prompt the user to fix with 'git rebase --edit-todo' or to
abort.

This allows to avoid doing half of a rebase before finding an error
and giving back what's left of the todo list to the user and prompt
him to fix when it might be too late for him to do so (he might have
to abort and restart the rebase).

3707995960 git rebase -i: warn about removed commits
Check if commits were removed (i.e. a line was deleted) and print
warnings or stop git rebase depending on the value of the
configuration variable rebase.missingCommitsCheck.

This patch gives the user the possibility to avoid silent loss of
information (losing a commit through deleting the line in this case)
if he wants.

Add the configuration variable rebase.missingCommitsCheck.
    - When unset or set to "ignore", no checking is done.
    - When set to "warn", the commits are checked, warnings are
      displayed but git rebase still proceeds.
    - When set to "error", the commits are checked, warnings are
      displayed and the rebase is stopped.
      (The user can then use 'git rebase --edit-todo' and
      'git rebase --continue', or 'git rebase --abort')

rebase.missingCommitsCheck defaults to "ignore".

c9266d5894 git-rebase -i: add command "drop" to remove a commit
Instead of removing a line to remove the commit, you can use the
command "drop" (just like "pick" or "edit"). It has the same effect as
deleting the line (removing the commit) except that you keep a visual
trace of your actions, allowing a better control and reducing the
possibility of removing a commit by mistake.

0e0aff4b4c rebase -i: do not leave a CHERRY_PICK_HEAD file behind
When skipping commits whose changes were already applied via `git rebase
--continue`, we need to clean up said file explicitly.

The same is not true for `git rebase --skip` because that will execute
`git reset --hard` as part of the "skip" handling in git-rebase.sh, even
before git-rebase--interactive.sh is called.

d17ec3a9da t3404: demonstrate CHERRY_PICK_HEAD bug
When rev-list's --cherry option does not detect that a patch has already
been applied upstream, an interactive rebase would offer to reapply it and
consequently stop at that patch with a failure, mentioning that the diff
is empty.

Traditionally, a `git rebase --continue` simply skips the commit in such a
situation.

However, as pointed out by Gábor Szeder, this leaves a CHERRY_PICK_HEAD
behind, making the Git prompt believe that a cherry pick is still going
on. This commit adds a test case demonstrating this bug.
