Abandoning an already applied change in "git rebase -i" with

rebase -i: do not leave a CHERRY_PICK_HEAD file behind
t3404: demonstrate CHERRY_PICK_HEAD bug
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.

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.

"git rebase -i" moved the "current" command from "todo" to "done" a
bit too prematurely, losing a step when a "pick" did not even start.
* ph/rebase-i-redo:
rebase -i: redo tasks that die during cherry-pick
When rebase--interactive processes a task, it removes the item from
the todo list and appends it to another list of executed tasks. If a
pick (this includes squash and fixup) fails before the index has
recorded the changes, take the corresponding item and put it on the todo
list again. Otherwise, the changes introduced by the scheduled commit
would be lost.
That kind of decision is possible since the cherry-pick command
signals why it failed to apply the changes of the given commit. Either
the changes are recorded in the index using a conflict (return value 1)
and rebase does not continue until they are resolved or the changes
are not recorded in the index (return value neither 0 nor 1) and
rebase has to try again with the same task.
Add a test cases for regression testing to the "rebase-interactive"
test suite.

In earlier days, the abbreviated commit object name shown to the end
users were generated with hardcoded --abbrev=7; 56895038 (rebase
-i: respect core.abbrev, 2013-09-28) tried to make it honor the user
specified core.abbrev, but it missed the very initial invocation of
the editor.
These days, we try to use the full 40-hex object names internally to
avoid ambiguity that can arise after rebase starts running. Newly
created objects during the rebase may share the same prefix with
existing commits listed in the insn sheet. These object names are
shortened just before invoking the sequence editor to present the
insn sheet to the end user, and then expanded back to full object
names when the editor returns.
But the code still used the shortened names when preparing the insn
sheet for the very first time, resulting "7 hexdigits or more"
output to the user. Change the code to use full 40-hex commit
object names from the very beginning to make things more uniform.

Ordinarily, we would say "VAR=VAL command" to execute a tested
command with environment variable(s) set only for that command.
This however does not work if 'command' is a shell function (most
notably 'test_must_fail'); the result of the assignment is retained
and affects later commands.
To avoid this, we used to assign and export environment variables
and run such a test in a subshell, like so:
(
VAR=VAL && export VAR &&
test_must_fail git command to be tested

As its very first action, t3404 installs (via set_fake_editor) a
specialized $EDITOR which simplifies automated 'rebase -i' testing. Many
tests rely upon this setting, thus tests which need a different editor
must take extra care upon completion to restore $EDITOR in order to
avoid breaking following tests. This places extra burden upon such tests
and requires that they undesirably have extra knowledge about
surrounding tests. Ease this burden by having each test install the
$EDITOR it requires, rather than relying upon a global setting.

The reason is that the shell that attempted to run the command exits with

git wrapper). But our smart run-command infrastructure detects this
special exit code and turns it into ENOENT, which in turn is interpreted

During an interactive rebase session, it is sometimes desirable to
run tests on each commit in the resulting history. This can be done
by adding "exec <test command>" when editing the insn sheet, but the
command used for testing is often the same for all resulting commits.
By passing "--exec <cmd>" from the command line, automatically add
these "exec" lines after each commit in the final history. To work
well with the --autosquash option, these are added at the end of
each run of "fixup" and "squash".

Number of columns required for change counts is now computed based on
the maximum number of changed lines instead of being fixed. This means
that usually a few more columns will be available for the filenames
and the graph.
The graph width logic is also modified to include enough space for
"Bin XXX -> YYY bytes".
If changes to binary files are mixed with changes to text files,
change counts are padded to take at least three columns. And the other
way around, if change counts require more than three columns, then
"Bin"s are padded to align with the change count. This way, the +-
part starts in the same column as "XXX -> YYY" part for binary files.
This makes the graph easier to parse visually thanks to the empty
column. This mimics the layout of diff --stat before this change.
Tests and the tutorial are updated to reflect the new --stat output.
This means either the removal of extra padding and/or the addition of
up to three extra characters to truncated filenames. One test is added
to check the graph alignment when a binary file change and text file
change of more than 999 lines are committed together.

When git-rebase--interactive stops due to a conflict and the only change
to be committed is in a submodule, the test for whether there is
anything to be committed ignores the staged submodule change. This
leads rebase to skip creating the commit for the change.
While unstaged submodule changes should be ignored to avoid needing to
update submodules during a rebase, it is safe to remove the
--ignore-submodules option to diff-index because --cached ensures that
it is only checking the index. This was discussed in [1] and a test is
included to ensure that unstaged changes are still ignored correctly.

After an "exec false" stops the rebase and gives the control back to

with this message, which may technically be correct, but does not point
at the real problem:

We could try auto-amending HEAD, but this goes against the logic of
.git/rebase-merge/author-script (see also the testcase 'auto-amend only
edited commits after "edit"' in t3404-rebase-interactive.sh) to
auto-amend something the user hasn't explicitely asked to edit.
Instead of doing anything automatically, detect the situation and give a
clean error message. While we're there, also clarify the error message in
case '. "$author_script"' fails, which now corresponds to really weird

Consider this graph:

\
F (topic2)
and the following three commands:
1. git rebase -i -p A
2. git rebase -i -p --onto F A
3. git rebase -i -p B
Currently, (1) and (2) will pick B, D, C, and E onto A and F,
respectively. However, (3) will only pick D and E onto B, but not C,
which is inconsistent with (1) and (2). As a result, we cannot modify C
during the interactive-rebase.
The current behavior also creates a bug if we do:
4. git rebase -i -p C
In (4), E is never picked. And since interactive-rebase resets "HEAD"
to "onto" before picking any commits, D and E are lost after the
interactive-rebase.
This patch fixes the inconsistency and bug by ensuring that all children
of upstream are always picked. This essentially reverts the commit:
d80d6bc146
When compiling the todo list, commits reachable from "upstream" should
never be skipped under any conditions. Otherwise, we lose the ability
to modify them like (3), and create a bug like (4).
Two of the tests contain a scenario like (3). Since the new behavior
added more commits for picking, these tests need to be updated to
account for the additional pick lines. A new test has also been added
for (4).

When we finish a rebase, our detached HEAD is at the final
result. We update the original branch ref with this result,
and then point the HEAD symbolic ref at the updated branch.
We write a reflog for the branch update, but not for the
update of HEAD.
Because we're already at the final result on the detached
HEAD, moving to the branch actually doesn't change our
commit sha1 at all. So in that sense, a reflog entry would
be pointless.
However, humans do read reflogs, and an entry saying "rebase

understanding what is going on.
