rebase -i: introduce --rebase-merges=[no-]rebase-cousins
When running `git rebase --rebase-merges` non-interactively with an
ancestor of HEAD as <upstream> (or leaving the todo list unmodified),
we would ideally recreate the exact same commits as before the rebase.
However, if there are commits in the commit range <upstream>.. that do not
have <upstream> as direct ancestor (i.e. if `git log <upstream>..` would
show commits that are omitted by `git log --ancestry-path <upstream>..`),
this is currently not the case: we would turn them into commits that have
<upstream> as direct ancestor.
Let's illustrate that with a diagram:
C
/ \
A - B - E - F
\ /
D
Currently, after running `git rebase -i --rebase-merges B`, the new branch
structure would be (pay particular attention to the commit `D`):
--- C' --
/ \
A - B ------ E' - F'
\ /
D'
This is not really preserving the branch topology from before! The
reason is that the commit `D` does not have `B` as ancestor, and
therefore it gets rebased onto `B`.
This is unintuitive behavior. Even worse, when recreating branch
structure, most use cases would appear to want cousins *not* to be
rebased onto the new base commit. For example, Git for Windows (the
heaviest user of the Git garden shears, which served as the blueprint
for --rebase-merges) frequently merges branches from `next` early, and
these branches certainly do *not* want to be rebased. In the example
above, the desired outcome would look like this:
--- C' --
/ \
A - B ------ E' - F'
\ /
-- D' --
Let's introduce the term "cousins" for such commits ("D" in the
example), and let's not rebase them by default. For hypothetical
use cases where cousins *do* need to be rebased, `git rebase
--rebase=merges=rebase-cousins` needs to be used.

pull,rebase: handle GIT_WORK_TREE better
You can't currently run git-pull or git-rebase from outside
of the work tree, even with GIT_WORK_TREE set, due to an
overeager require_work_tree function. Commit e2eb527
documents this problem and provides the infrastructure for a
fix, but left it to later commits to audit and update
individual scripts.
Changing these scripts to use require_work_tree_exists is
easy to verify. We immediately call cd_to_toplevel, anyway.
Therefore no matter which function we use, the state
afterwards is one of:
1. We have a work tree, and we are at the top level.
2. We don't have a work tree, and we have died.
The only catch is that we must also make sure no code that
ran before the cd_to_toplevel assumed that we were already
in the working tree.
In this case, we will only have included shell libraries and
called set_reflog_action, neither of which care about the
current working directory at all.

rebase: introduce the --rebase-merges option
Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?
The original attempt to answer this was: git rebase --preserve-merges.
However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.
Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.
The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.
This made it impossible, for example, to reorder commits. Not to mention
to move commits between branches or, deity forbid, to split topic branches
into two.
Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.
Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.
That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.
With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--rebase-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

rebase -i: introduce --rebase-merges=[no-]rebase-cousins
When running `git rebase --rebase-merges` non-interactively with an
ancestor of HEAD as <upstream> (or leaving the todo list unmodified),
we would ideally recreate the exact same commits as before the rebase.
However, if there are commits in the commit range <upstream>.. that do not
have <upstream> as direct ancestor (i.e. if `git log <upstream>..` would
show commits that are omitted by `git log --ancestry-path <upstream>..`),
this is currently not the case: we would turn them into commits that have
<upstream> as direct ancestor.
Let's illustrate that with a diagram:
C
/ \
A - B - E - F
\ /
D
Currently, after running `git rebase -i --rebase-merges B`, the new branch
structure would be (pay particular attention to the commit `D`):
--- C' --
/ \
A - B ------ E' - F'
\ /
D'
This is not really preserving the branch topology from before! The
reason is that the commit `D` does not have `B` as ancestor, and
therefore it gets rebased onto `B`.
This is unintuitive behavior. Even worse, when recreating branch
structure, most use cases would appear to want cousins *not* to be
rebased onto the new base commit. For example, Git for Windows (the
heaviest user of the Git garden shears, which served as the blueprint
for --rebase-merges) frequently merges branches from `next` early, and
these branches certainly do *not* want to be rebased. In the example
above, the desired outcome would look like this:
--- C' --
/ \
A - B ------ E' - F'
\ /
-- D' --
Let's introduce the term "cousins" for such commits ("D" in the
example), and let's not rebase them by default. For hypothetical
use cases where cousins *do* need to be rebased, `git rebase
--rebase=merges=rebase-cousins` needs to be used.

git-rebase: make --allow-empty-message the default
rebase backends currently behave differently with empty commit messages,
largely as a side-effect of the different underlying commands on which
they are based. am-based rebases apply commits with an empty commit
message without stopping or requiring the user to specify an extra flag.
(It is interesting to note that am-based rebases are the default rebase
type, and no one has ever requested a --no-allow-empty-message flag to
change this behavior.) merge-based and interactive-based rebases (which
are ultimately based on git-commit), will currently halt on any such
commits and require the user to manually specify what to do with the
commit and continue.
One possible rationale for the difference in behavior is that the purpose
of an "am" based rebase is solely to transplant an existing history, while
an "interactive" rebase is one whose purpose is to polish a series before
making it publishable. Thus, stopping and asking for confirmation for a
possible problem is more appropriate in the latter case. However, there
are two problems with this rationale:
1) merge-based rebases are also non-interactive and there are multiple
types of rebases that use the interactive machinery but are not
explicitly interactive (e.g. when either --rebase-merges or
--keep-empty are specified without --interactive). These rebases are
also used solely to transplant an existing history, and thus also
should default to --allow-empty-message.
2) this rationale only says that the user is more accepting of stopping
in the case of an explicitly interactive rebase, not that stopping
for this particular reason actually makes sense. Exploring whether
it makes sense, requires backing up and analyzing the underlying
commands...
If git-commit did not error out on empty commits by default, accidental
creation of commits with empty messages would be a very common occurrence
(this check has caught me many times). Further, nearly all such empty
commit messages would be considered an accidental error (as evidenced by a
huge amount of documentation across version control systems and in various
blog posts explaining how important commit messages are). A simple check
for what would otherwise be a common error thus made a lot of sense, and
git-commit gained an --allow-empty-message flag for special case
overrides. This has made commits with empty messages very rare.
There are two sources for commits with empty messages for rebase (and
cherry-pick): (a) commits created in git where the user previously
specified --allow-empty-message to git-commit, and (b) commits imported
into git from other version control systems. In case (a), the user has
already explicitly specified that there is something special about this
commit that makes them not want to specify a commit message; forcing them
to re-specify with every cherry-pick or rebase seems more likely to be
infuriating than helpful. In case (b), the commit is highly unlikely to
have been authored by the person who has imported the history and is doing
the rebase or cherry-pick, and thus the user is unlikely to be the
appropriate person to write a commit message for it. Stopping and
expecting the user to modify the commit before proceeding thus seems
counter-productive.
Further, note that while empty commit messages was a common error case for
git-commit to deal with, it is a rare case for rebase (or cherry-pick).
The fact that it is rare raises the question of why it would be worth
checking and stopping on this particular condition and not others. For
example, why doesn't an interactive rebase automatically stop if the
commit message's first line is 2000 columns long, or is missing a blank
line after the first line, or has every line indented with five spaces, or
any number of other myriad problems?
Finally, note that if a user doing an interactive rebase does have the
necessary knowledge to add a message for any such commit and wants to do
so, it is rather simple for them to change the appropriate line from
'pick' to 'reword'. The fact that the subject is empty in the todo list
that the user edits should even serve as a way to notify them.
As far as I can tell, the fact that merge-based and interactive-based
rebases stop on commits with empty commit messages is solely a by-product
of having been based on git-commit. It went without notice for a long
time precisely because such cases are rare. The rareness of this
situation made it difficult to reason about, so when folks did eventually
notice this behavior, they assumed it was there for a good reason and just
added an --allow-empty-message flag. In my opinion, stopping on such
messages not desirable in any of these cases, even the (explicitly)
interactive case.

rebase: refactor reading of state
The code reading the state saved in $merge_dir or $rebase_dir is
currently spread out in many places, making it harder to read and to
introduce additional state. Extract this code into one method that
reads the state. Only extract the code associated with the state that
is written when the rebase is initiated. Leave the state that changes
for each commmit, at least for now.
Currently, when resuming a merge-based rebase using --continue or
--skip, move_to_original_branch (via finish_rb_merge) will be called
without head_name and orig_head set. These variables are then lazily
read in move_to_original_branch if head_name is not set (together with
onto, which is unnecessarily read again). Change this by always
eagerly reading the state, for both am-based and merge-based rebase,
in the --continue and --skip cases. Note that this does not change the
behavior for am-based rebase, which read the state eagerly even before
this commit.
Reading the state eagerly means that part of the state will sometimes
be read unnecessarily. One example is when the rebase is continued,
but stops again at another merge conflict. Another example is when the
rebase is aborted. However, since both of these cases involve user
interaction, the delay is hopefully not noticeable. The
call_merge/continue_merge loop is not affected.

rebase: refactor reading of state
The code reading the state saved in $merge_dir or $rebase_dir is
currently spread out in many places, making it harder to read and to
introduce additional state. Extract this code into one method that
reads the state. Only extract the code associated with the state that
is written when the rebase is initiated. Leave the state that changes
for each commmit, at least for now.
Currently, when resuming a merge-based rebase using --continue or
--skip, move_to_original_branch (via finish_rb_merge) will be called
without head_name and orig_head set. These variables are then lazily
read in move_to_original_branch if head_name is not set (together with
onto, which is unnecessarily read again). Change this by always
eagerly reading the state, for both am-based and merge-based rebase,
in the --continue and --skip cases. Note that this does not change the
behavior for am-based rebase, which read the state eagerly even before
this commit.
Reading the state eagerly means that part of the state will sometimes
be read unnecessarily. One example is when the rebase is continued,
but stops again at another merge conflict. Another example is when the
rebase is aborted. However, since both of these cases involve user
interaction, the delay is hopefully not noticeable. The
call_merge/continue_merge loop is not affected.

rebase: use the new git-rebase--preserve-merges.sh
Create a new type of rebase, "preserve-merges", used when rebase is
called with -p.
Before that, the type for preserve-merges was "interactive", and some
places of this script compared $type to "interactive". Instead, the code
now checks if $interactive_rebase is empty or not, as it is set to
"explicit" when calling an interactive rebase (and, possibly, one of its
submodes), and "implied" when calling one of its
submodes (eg. preserve-merges) *without* interactive rebase.
It also detects the presence of the directory "$merge_dir"/rewritten
left by the preserve-merges script when calling rebase --continue,
--skip, etc., and, if it exists, sets the rebase mode to
preserve-merges. In this case, interactive_rebase is set to "explicit",
as "implied" would break some tests.

rebase -i: rewrite complete_action() in C
This rewrites complete_action() from shell to C.
A new mode is added to rebase--helper (`--complete-action`), as well as
a new flag (`--autosquash`).
Finally, complete_action() is stripped from git-rebase--interactive.sh.
The original complete_action() would return the code 2 when the todo
list contained no actions. This was a special case for rebase -i and
-p; git-rebase.sh would then apply the autostash, delete the state
directory, and die with the message "Nothing to do". This cleanup is
rewritten in C instead of returning 2. As rebase -i no longer returns
2, the comment describing this behaviour in git-rebase.sh is updated to
reflect this change.
The message "Nothing to do" is now printed with error(), and so becomes
"error: nothing to do". Some tests in t3404 check this value, so they
are updated to fit this change.
The first check might seem useless as we write "noop" to the todo list
if it is empty. Actually, the todo list might contain commented
commands (ie. empty commits). In this case, complete_action() won’t
write "noop", and will abort without starting the editor.

rebase: introduce the --rebase-merges option
Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?
The original attempt to answer this was: git rebase --preserve-merges.
However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.
Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.
The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.
This made it impossible, for example, to reorder commits. Not to mention
to move commits between branches or, deity forbid, to split topic branches
into two.
Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.
Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.
That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.
With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--rebase-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

rebase -i: introduce --rebase-merges=[no-]rebase-cousins
When running `git rebase --rebase-merges` non-interactively with an
ancestor of HEAD as <upstream> (or leaving the todo list unmodified),
we would ideally recreate the exact same commits as before the rebase.
However, if there are commits in the commit range <upstream>.. that do not
have <upstream> as direct ancestor (i.e. if `git log <upstream>..` would
show commits that are omitted by `git log --ancestry-path <upstream>..`),
this is currently not the case: we would turn them into commits that have
<upstream> as direct ancestor.
Let's illustrate that with a diagram:
C
/ \
A - B - E - F
\ /
D
Currently, after running `git rebase -i --rebase-merges B`, the new branch
structure would be (pay particular attention to the commit `D`):
--- C' --
/ \
A - B ------ E' - F'
\ /
D'
This is not really preserving the branch topology from before! The
reason is that the commit `D` does not have `B` as ancestor, and
therefore it gets rebased onto `B`.
This is unintuitive behavior. Even worse, when recreating branch
structure, most use cases would appear to want cousins *not* to be
rebased onto the new base commit. For example, Git for Windows (the
heaviest user of the Git garden shears, which served as the blueprint
for --rebase-merges) frequently merges branches from `next` early, and
these branches certainly do *not* want to be rebased. In the example
above, the desired outcome would look like this:
--- C' --
/ \
A - B ------ E' - F'
\ /
-- D' --
Let's introduce the term "cousins" for such commits ("D" in the
example), and let's not rebase them by default. For hypothetical
use cases where cousins *do* need to be rebased, `git rebase
--rebase=merges=rebase-cousins` needs to be used.

rebase: use the new git-rebase--preserve-merges.sh
Create a new type of rebase, "preserve-merges", used when rebase is
called with -p.
Before that, the type for preserve-merges was "interactive", and some
places of this script compared $type to "interactive". Instead, the code
now checks if $interactive_rebase is empty or not, as it is set to
"explicit" when calling an interactive rebase (and, possibly, one of its
submodes), and "implied" when calling one of its
submodes (eg. preserve-merges) *without* interactive rebase.
It also detects the presence of the directory "$merge_dir"/rewritten
left by the preserve-merges script when calling rebase --continue,
--skip, etc., and, if it exists, sets the rebase mode to
preserve-merges. In this case, interactive_rebase is set to "explicit",
as "implied" would break some tests.

rebase: use the new git-rebase--preserve-merges.sh
Create a new type of rebase, "preserve-merges", used when rebase is
called with -p.
Before that, the type for preserve-merges was "interactive", and some
places of this script compared $type to "interactive". Instead, the code
now checks if $interactive_rebase is empty or not, as it is set to
"explicit" when calling an interactive rebase (and, possibly, one of its
submodes), and "implied" when calling one of its
submodes (eg. preserve-merges) *without* interactive rebase.
It also detects the presence of the directory "$merge_dir"/rewritten
left by the preserve-merges script when calling rebase --continue,
--skip, etc., and, if it exists, sets the rebase mode to
preserve-merges. In this case, interactive_rebase is set to "explicit",
as "implied" would break some tests.

git-rebase: error out when incompatible options passed
git rebase has three different types: am, merge, and interactive, all of
which are implemented in terms of separate scripts. am builds on git-am,
merge builds on git-merge-recursive, and interactive builds on
git-cherry-pick. We make use of features in those lower-level commands in
the different rebase types, but those features don't exist in all of the
lower level commands so we have a range of incompatibilities. Previously,
we just accepted nearly any argument and silently ignored whichever ones
weren't implemented for the type of rebase specified. Change this so the
incompatibilities are documented, included in the testsuite, and tested
for at runtime with an appropriate error message shown.
Some exceptions I left out:
* --merge and --interactive are technically incompatible since they are
supposed to run different underlying scripts, but with a few small
changes, --interactive can do everything that --merge can. In fact,
I'll shortly be sending another patch to remove git-rebase--merge and
reimplement it on top of git-rebase--interactive.
* One could argue that --interactive and --quiet are incompatible since
--interactive doesn't implement a --quiet mode (perhaps since
cherry-pick itself does not implement one). However, the interactive
mode is more quiet than the other modes in general with progress
messages, so one could argue that it's already quiet.

rebase: use the new git-rebase--preserve-merges.sh
Create a new type of rebase, "preserve-merges", used when rebase is
called with -p.
Before that, the type for preserve-merges was "interactive", and some
places of this script compared $type to "interactive". Instead, the code
now checks if $interactive_rebase is empty or not, as it is set to
"explicit" when calling an interactive rebase (and, possibly, one of its
submodes), and "implied" when calling one of its
submodes (eg. preserve-merges) *without* interactive rebase.
It also detects the presence of the directory "$merge_dir"/rewritten
left by the preserve-merges script when calling rebase --continue,
--skip, etc., and, if it exists, sets the rebase mode to
preserve-merges. In this case, interactive_rebase is set to "explicit",
as "implied" would break some tests.

rebase: silence "git checkout" for noop rebase
When the branch to be rebased is already up to date, we
"git checkout" the branch, print an "up to date" message,
and end the rebase early. However, our checkout may print
"Switched to branch 'foo'" or "Already on 'foo'", even if
the user has asked for "--quiet".
We should avoid printing these messages at all, "--quiet" or
no. Since the rebase is a noop, this checkout can be seen as
optimizing out these other two checkout operations (that
happen in a real rebase):
1. Moving to the detached HEAD to start the rebase; we
always feed "-q" to checkout there, and instead rely on
our own custom message (which respects --quiet).
2. Finishing a rebase, where we move to the final branch.
Here we actually use update-ref rather than
git-checkout, and produce no messages.
