Add "drop commit-object-name subject" command as another way to
skip replaying of a commit in "rebase -i", and then punish those
who do not use it (and instead just remove the lines) by throwing
a warning.
* gr/rebase-i-drop-warn:
git rebase -i: add static check for commands and SHA-1
git rebase -i: warn about removed commits
git-rebase -i: add command "drop" to remove a commit
|

Abandoning an already applied change in "git rebase -i" with
"--continue" left CHERRY_PICK_HEAD and confused later steps.

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).

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".

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.

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.

These are tests which are missing a link in their &&-chain,

the test. Most of these are of the form:

The main point of the test is to verify the output, and a

# Rebase 46640c6..5568fd5 onto 46640c6 (4 TODO item(s))
On Mac OS X, however, it renders as:

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
)
But with "env" utility, we should be able to say:
test_must_fail env VAR=VAL git command to be tested
which is much shorter and easier to read.

The 'todo' sheet for interactive rebase shows abbreviated SHA-1's and
then performs its operations upon those shortened values. This can lead
to an abort if the SHA-1 of a reworded or edited commit is no longer
unique within the abbreviated SHA-1 space and a subsequent SHA-1 in the
todo list has the same abbreviated value.
For example:
edit f00dfad first
pick badbeef second
If, after editing, the new SHA-1 of "first" also has prefix badbeef,
then the subsequent 'pick badbeef second' will fail since badbeef is no
longer a unique SHA-1 abbreviation:
error: short SHA1 badbeef is ambiguous.
fatal: Needed a single revision
Invalid commit name: badbeef
Fix this problem by expanding the SHA-1's in the todo list before
performing the operations.

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.

Now that the "checkout" invoked internally from "rebase -i" knows to
honor GIT_REFLOG_ACTION, we can start to use it to write a better
reflog message when "rebase anotherbranch", "rebase --onto branch",
etc. internally checks out the new fork point. We will write:
rebase -i: checkout master
instead of the old
rebase -i
As all the calls git-rebase--interactive make to underlying git
commands that leave reflog messages are preceded by the internal
comment_for_reflog helper function, which uses the original value of
the GIT_REFLOG_ACTION variable it saw when it first started, the new
assignments to GIT_REFLOG_ACTION actively contaminate the value of
the variable, knowing that it will be reset to a sane value before
it is used again. This does not generally hold true but it should
suffice for now.

When the todo sheet of interactive rebase instructs to run a non-existing
command, the operation stops with the following error:
Execution failed: no-such
You can fix the problem, and then run
git rebase --continue
fatal: 'rebase' appears to be a git command, but we were not
able to execute it. Maybe git-rebase is broken?
The reason is that the shell that attempted to run the command exits with
code 127. rebase--interactive just forwards this code to the caller (the
git wrapper). But our smart run-command infrastructure detects this
special exit code and turns it into ENOENT, which in turn is interpreted
by the git wrapper as if the external command that it just executed did
not exist. This is finally translated to the misleading last two lines in
error message cited above.
Fix it by translating the error code before it is forwarded.

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.
