From: Phillip Wood <phillip.wood@dunelm.org.uk>

When the builtin rebase starts an interactive rebase it parses the
options and then repackages them and forks `rebase--interactive`. This
series refactors rebase--interactive so that interactive rebases can
be started by the builtin rebase without forking. My motivation was to
make it easier to debug the sequencer but this should help future
maintainability.

This series involves some code movement so viewing the diffs with
--color-moved is recommended.

These patches are based on a merge of master [e902e9bcae ("The second
batch", 2019-03-11)] and ag/sequencer-reduce-rewriting-todo ed35d18841
("rebase--interactive: move transform_todo_file()", 2019-03-05). They
can be fetched from the tag rebase-i-no-fork/rfc at
https://github.com/phillipwood/git.git

Phillip Wood (11):
  sequencer: always discard index after checkout
  rebase: rename write_basic_state()
  rebase: use OPT_RERERE_AUTOUPDATE()
  rebase -i: combine rebase--interactive.c with rebase.c
  rebase -i: remove duplication
  rebase -i: use struct commit when parsing options
  rebase -i: use struct object_id for squash_onto
  rebase -i: use struct rebase_options to parse args
  rebase -i: use struct rebase_options in do_interactive_rebase()
  rebase: use a common action enum
  rebase -i: run without forking rebase--interactive

From: Phillip Wood <phillip.wood@dunelm.org.uk>

As the checkout runs in a separate process our index will be out of date
so it should be discarded. The existing callers are not doing this
consistently so do it here to avoid the callers having to worry about
it.

This fixes some test failures that happen if do_interactive_rebase() is
called without forking rebase--interactive which we will implement
shortly. Running

  git rebase -i master topic

starting on master created empty todo lists because all the commits in
topic were marked as cherry-picks. After topic was checked out in
prepare_branch_to_be_rebased() the working tree contained the contents
from topic but the index contained master and the cache entries were
still valid. This meant that diff_populate_filespec() which loads the
blobs when calculating patch-id's ended up reading the contents for
master from the working tree which actually contained topic.

Notes:
    It would perhaps be better to pass around the_index rather than
    the_repository

As we have a macro for this it makes sense to use it. Having
cmd_rebase() and cmd_rebase__interactive() use the same values for
this option will be helpful when we start running interactive rebases
without forking rebase--interactive.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

In order to run `rebase -i` without forking `rebase--interactive` it
will be convenient to have all the code from rebase--interactive.c in
rebase.c. This is a straight forward copy of the code from
rebase--interactive.c, it will be simplified slightly in the next
commit.

path_state_dir() and merge_dir() refer to the same path so remove one of
them.

This is in preparation for using `struct rebase_options` when parsing
options in cmd_rebase__interactive(). Using a string for onto,
restrict_revision and upstream, was a hangover from the scripted version
of rebase. The functions that use these variables are updated to take a
`struct commit`.

Notes:
    I'm not sure if parse_opt_commit() should be in parse-options-cb.c or
    not, it depends if it is going to be useful elsewhere.

More preparation for using `struct rebase_options` in
cmd_rebase__interactive(). Using a string was a hangover from the
scripted version of rebase, update the functions that use `squash_onto`
to take a `sturct object_id`.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

In order to run `rebase -i` without forking `rebase--interactive` it
will be convenient to use the same structure when parsing the options in
cmd_rebase() and cmd_rebase__interactive().

From: Phillip Wood <phillip.wood@dunelm.org.uk>

All the parameters that are passed to do_interactive_rebase() apart from
`flags` are already in `struct rebase_options` so there is no need to
pass them separately.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

cmd_rebase() and cmd_rebase__interactive() used different enums to hold
the current action. Change to using a common enum so the values are the
same when we change `rebase -i` to avoid forking `rebase--interactive`.

Notes:
    I'm not sure what to do with action_names, I moved it to keep it near
    the definition of the enum. The extra commands in the enum are not
    traced so they don't need to be in action_names but it looks odd to
    leave them out. Also I don't understand why action_names in NULL
    terminated or the names are marked for translation as it is used in
    	trace2_cmd_mode(action_names[action]);
    so we don't use the NULL termination or translate the names (I'd be
    surprised if we did for tracing)

From: Phillip Wood <phillip.wood@dunelm.org.uk>

When the builtin rebase starts an interactive rebase it parses the
options and then repackages them and forks
`rebase--interactive`. Separate the option parsing in
cmd_rebase__interactive() from the business logic to allow interactive
rebases can be run without forking `rebase__interactive` by calling
run_rebase_interactive() directly. This makes it easy to debug the
sequencer without worrying about attaching to child processes. It also
makes it easy to remove cmd_rebase__interactive() in the future when
git-legacy-rebase.sh and git-rebase--preserve-merges.sh are retired.

Making them for translation is a bug in the recent b3a5d5a80c
("trace2:data: add subverb for rebase", 2019-02-22) and just looks like
copy/paste cargo-culting from somewhere else, and likewise with the
trailing NULL which doesn't make sense in this case.

Not by a large margin. For sequencer.c most operations require more
than just the index and passing 'struct repository *' around has been
the norm. And as soon as you need to load the index back (not sure if
you should do it here btw, after discard_index, since we have the
index loaded before) you need 'struct repository' not 'struct
index_state'.

Although I'm not very familiar with the rebase code, this series looks
good to me.

Just a that the t/perf/*rebase* numbers look much better with this. I
don't have these in front of me anymore, but over 10 runs with -O3 one
of those long-runnings test was 30% faster.

Another one (rebase -i) went from 0.02 to 0.01 sec, with that short
amount of time I wonder (but didn't dig) if the test itself is broken...

This calls init_config() and then sets .action; does it revert to
what dl/merge-cleanup-scissors-fix wants to do, which flipped the
order to fix some bug?  It is a bit hard to tell.

Unfortunately because of the earlier huge code movement the changes
to _this_ file does not conflict and cleanly merges, but because the
other file is removed by this series while a topic in flight updates
it, the semantic conflict like this luckily gets discovered.

Especially since this is still an RFC, I'd preferred to see it

symbols that need to be visible with each other after renaming them

Thanks, I think I'll leave it as it is then. After we checkout the new 
base we reload the index in the loop that picks the commits. For 'rebase 
<upstream> <branch>' after we checkout <branch> we create the todo-list 
which involves a revision walk and then checkout the new base. I'm not 
entirely sure if it needs reloading before we create the todo list but I 
think it probably not as I don't think rebase--interactive.c loads the 
index (which would explain why this only becomes an issue when we stop 
forking rebase--interactive from rebase because then rebase.c has loaded 
the index to check there are no uncommitted changes)

Best Wishes

That's surprising I wouldn't expect that much change as the time taken 
to fork shouldn't be that significant compared to the overall running 
time. I'll make a note to have a look at those tests.

Yeah, that sounds suspicious

Thanks for sharing those results

Thanks for clarifying that, I'll add a preparatory patch at the

dl/merge-cleanup-scissors-fix changes sequencer_init_config() to depend 
on the value of action so action should to be set first. What is in pu 
at the moment in not quite right (though I'm not sure what the practical 
implications are as it looks like the rebase tests are passing[1]).

I'm happy to try doing that, though the textual conflict would be in a 
different place in the file to the semantic conflict but at least they'd 
both be in the same file. I think it would only need to share the 
definitions of struct rebase_options, enum rebase_action and the 
declaration of run_rebase_interactive(). Would you be happy with the 
addition of builtin/rebase.h (there don't seem to be another headers in 
that directory). We could leave rebase--interactive.c around until 
rebase--preserve-merges.sh is finally removed.

Best Wishes

I wonder if `struct rebase_options` and `struct replay_options` could be
merged, or at least have `replay_options` used in `rebase_options`,
instead of converting one to the other.  I think it would make things
simpler and cleaner, but I don’t know how hard it would be, or if my
assumption is correct.

Cheers,
Alban

Yes, it actually is the reason why I left the seemingly-wrong merge
in 'pu' on purpose to see if we have enough test coverage.

I think dl/merge-cleanup-scissors-fix is getting solid enough, so a
better alternative may be to base this on top of

	reset e902e9bcae ;# The second batch
	merge ag/sequencer-reduce-rewriting-todo
	merge dl/merge-cleanup-scissors-fix

instead of basing it only on ag/sequencer-reduce-rewriting-todo.

Thanks.

Hi Alban

sorry for the slow reply, I think you're probably off-list for a while

I did consider doing that, but there are a few subtle differences in the 
way the options are stored in each struct (eg the gpg option has a 
leading -S in struct rebase_options but not struct replay_options) and I 
think it would be a bit of a faff to align them as it would mean messing 
with the code uses them and the code that reads/writes the various state 
files (we cannot change the on-disk format without breaking things - 
sometimes users start a rebase with one version of git bundled with 
something like tig and then continue on the command-line with a 
different version). I'd prefer to leave it as a future cleanup once this 
series has been merged.

Best Wishes

Thanks for the feedback on the last version. I've updated the final
commit message to mention the speed up reported by Ævar. I've also
removed the translation of the trace strings. Apart from that this
series is unchanged. There shouldn't be any merge conflicts with the
updated dl/merge-cleanup-scissors-fix I posted earlier. (There are
conflicts with other series but they are already resolved in pu)

This series still based on a merge of master [e902e9bcae ("The second
batch", 2019-03-11)] and ag/sequencer-reduce-rewriting-todo ed35d18841
("rebase--interactive: move transform_todo_file()", 2019-03-05). It

As the checkout runs in a separate process our index will be out of date
so it should be discarded. The existing callers are not doing this
consistently so do it here to avoid the callers having to worry about
it.

This fixes some test failures that happen if do_interactive_rebase() is
called without forking rebase--interactive which we will implement
shortly. Running

  git rebase -i master topic

starting on master created empty todo lists because all the commits in
topic were marked as cherry-picks. After topic was checked out in
prepare_branch_to_be_rebased() the working tree contained the contents
from topic but the index contained master and the cache entries were
still valid. This meant that diff_populate_filespec() which loads the
blobs when calculating patch-id's ended up reading the contents for
master from the working tree which actually contained topic.

This clashes with a function in sequencer.c

As we have a macro for this it makes sense to use it. Having
cmd_rebase() and cmd_rebase__interactive() use the same values for
this option will be helpful when we start running interactive rebases
without forking rebase--interactive.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

In order to run `rebase -i` without forking `rebase--interactive` it
will be convenient to have all the code from rebase--interactive.c in
rebase.c. This is a straight forward copy of the code from
rebase--interactive.c, it will be simplified slightly in the next
commit.

path_state_dir() and merge_dir() refer to the same path so remove one of
them.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

This is in preparation for using `struct rebase_options` when parsing
options in cmd_rebase__interactive(). Using a string for onto,
restrict_revision and upstream, was a hangover from the scripted version
of rebase. The functions that use these variables are updated to take a
`struct commit`.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

More preparation for using `struct rebase_options` in
cmd_rebase__interactive(). Using a string was a hangover from the
scripted version of rebase, update the functions that use `squash_onto`
to take a `sturct object_id`.

In order to run `rebase -i` without forking `rebase--interactive` it
will be convenient to use the same structure when parsing the options in
cmd_rebase() and cmd_rebase__interactive().

From: Phillip Wood <phillip.wood@dunelm.org.uk>

All the parameters that are passed to do_interactive_rebase() apart from
`flags` are already in `struct rebase_options` so there is no need to
pass them separately.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

cmd_rebase() and cmd_rebase__interactive() used different enums to hold
the current action. Change to using a common enum so the values are the
same when we change `rebase -i` to avoid forking `rebase--interactive`.

From: Phillip Wood <phillip.wood@dunelm.org.uk>

When the builtin rebase starts an interactive rebase it parses the
options and then repackages them and forks
`rebase--interactive`. Separate the option parsing in
cmd_rebase__interactive() from the business logic to allow interactive
rebases can be run without forking `rebase__interactive` by calling
run_rebase_interactive() directly.

Starting interactive rebases without forking makes it easy to debug
the sequencer without worrying about attaching to child
processes. Ævar has also reported that some of the rebase perf tests
are 30% faster [1].

This patch also makes it easy to remove cmd_rebase__interactive() in
the future when git-legacy-rebase.sh and
git-rebase--preserve-merges.sh are retired.

That's an improvement independent from the rest of the patches.

Now we've had the C99 designated initialisers weather balloon
changes for some time in our codebase, perhaps we can ensure that
these entries match the intended & corresponding "enum action"
constants?  If we can also ensure that the array is large enough so
that the trace2 call done like so

	trace2_cmd_mode(action_names[action])

is safe, that would be good, but that is secondary.

Thanks.

Yes I only included it as I move the definition later in the series

If what's below is ok, I'll send a re-roll, I wasn't sure if it was best
to die if action is larger than the array of names or just use a
default. My worrying with dying is that it wont be caught by tests and
will cause a problem for users who enable tracing. At least with what's
below they can still rebase and hopefully report a bug about unknown
action in their trace output.

Best Wishes

Phillip
