Yeah, that's fair. It was totally unclear in my work-in-progress
patches, as I had ideas taking it in both directions. Then Christian
and Dscho came along and said they wanted to use it for server-side
rebasing & cherry-picking. Christian did some good cleanup of my
patches, but I think your comment here is just reflecting that there's
still a bit more to do.
I'd say for now that we should expunge the worktree & index updating,
any conflict handling beyond exit status, mark it as plumbing, and
focus strictly on server-side use for now.

Thanks for the clarification.
Let me also add a clarification about this text you're responding to:
the document that Christian copied into this portion of the cover
letter wasn't talking about this particular series he submitted, but
about the broader design goals I was working on. I don't want a
run_git_commit() function within replay.c, even for commit message
editing, for picking merge commits, or for handling staged changes
after resuming from an interactive rebase. I'd even say I don't want
it for failure handling, either, though that one is less important.

Guess how many years I've been gathering my ideas for git-replay. ;-)
One thing to note here, though, is the checkout handling still isn't
fully fixed, and it may be impossible to fix at this point. In
particular, `git rebase --abort` doesn't return people to the original
branch when otherbranch is specified, which is problematic in
conjunction with other options (see e.g.
https://lore.kernel.org/git/xmqqft5icsd9.fsf@gitster.c.googlers.com/).

Yeah, this particular paragraph I suspect is from about 18 months ago.
(See also where I responded to the update-refs series about this
https://lore.kernel.org/git/CABPp-BEOV53oBoBp4YjiRfksZMmAADanZUUemhxwn7Wor=m-nA@mail.gmail.com/).
However, I'd still say the statement is true, it just needs to be
focused on the divergent branches. The use of HEAD (or more generally
exactly 3 commitish-es), as done in rebase, is going to make it really
awkward to introduce any kind of command line UI for handling rebasing
of multiple divergent branches. I'm not sure it even makes sense.
git-replay has done it for over a year, and I think it makes sense
specifically because it got rid of the problematic assumptions
hard-wired into the command line UI.

Yes, absolutely. Especially since I'm very focused on having
operations be O(changes), not O(size-of-repo). The amount of work
people go through to avoid backporting because checking out other
branches is too expensive is impressive. But designing things for the
user that needs scaling to big repos isn't always the friendliest to
new users. And I admittedly am focused on performance above other
aspects, and in some cases that might leave new users behind.

Oh, sure, there are people who will like different options and
configurations. Non-performant features can certainly be options, I
was mostly harping on the defaults for git-replay. It should default
to fast, even if/when it moves beyond server-side only.

Which could be done as a very simple post-operation check: do pre- and
post- hashes match? No need for a bunch of logic to check what's
going to happen that'll result in slow startup in large repositories.
Default should be fast and scale to large repos.

Adding an option for writing HEAD's reflog at every step along the way
might be reasonable. But I specifically was designing a new command
with speed as priority number 1. Updating some external file with
every commit thus should not be the default for this new command. I
know that's incompatible with how git-rebase works, but this isn't
rebase.
Actually, there's a second problem as well. git-replay shouldn't
update _anything_ (other than adding new un-referenced
blobs/trees/commits), until it is entirely done. In fact, even when
it's done, it doesn't update any refs by default; it simply prints out
some "update-ref" instructions for `git update-ref --stdin` (though I
was thinking of adding a flag that would make git-replay also do the
ref updates, as the very final thing the program did).
And there's a third problem. HEAD isn't being updated in many cases,
so why should its reflog be?

The author script, commit message, list of rewritten commits, todo
list and done files are all control structures that are part of that
directory of files I was complaining about. As far as I can tell, you
said it's not an issue, but then immediately said the opposite. What
did you take the "directory of files" control structures to mean?
...and is there some other way I could word this that would be better?
Also, if we speed up the other stuff enough, the writing of the
control files becomes much more important. See the example elsewhere
where I mentioned that for a cherry-pick of a single commit that took
a minute under git-rebase, that actually creating the new toplevel
tree only required like 11 milliseconds. If we can speed things up
dramatically enough, then all the stuff that used to just not matter,
suddenly starts mattering a lot. (This happened a lot when I was
rewriting the merge machinery and optimizing it.) And, I think that
writing one file is going to be faster than writing N files
(especially on spinny disks, and yes my laptop has a spinny disk).
Also, single file control structures are easier to make safe against
an ill-timed Ctrl-C, though I suspect that's so rarely a problem that
it may not be worth worrying much about.

...and when not committing staged changes after a stopped interactive
rebase, and when not trying to ensure identical error messages when an
issue is hit. :-)
This is good; sequencer is always improving. If it could just stop
calling git commit in these four extra cases, we'd be rid of the
git-commit forking for good.

git-fast-export and git-fast-import do not run hooks, in part for
speed. I don't think git-fast-patch, i.e. git-replay should either,
at least not by default. I'm well aware that it's impossible to make
that kind of change to git-rebase, but I'm not trying to design
another rebase.
Another thing that might horrify you that I don't think I wrote down
is that when interactivity is added, I don't want replay to pre-parse
and validate the script, much like fast-import doesn't pre-parse and
validate its input. Not validating would be anathema to how rebase
operates (because rebase muddies things as it goes -- the worktree and
the index AND refs AND reflogs, and it's slow, so you don't want to
start down that path until you're confident that people didn't make
simple mistakes). As such, this is a change that I'd never even
consider suggesting for rebase, but it's exactly the kind of thing I
want for replay.

pre-rebase has a broken design; it already doesn't work correctly with
Stolee's --ref-update option. So, even if we wanted to support this
kind of functionality, it certainly wouldn't be that script.
Also, the name is pre-rebase, not pre-cherry-pick, and doesn't apply
to both commands. That means there's a second reason the design is
broken. So, even if we wanted to support this kind of functionality,
it'd have to be a differently named script with a different design.
But, perhaps more importantly than either of the above, is that replay
doesn't change any refs, so why do we need a hook to prevent it from
changing refs?

Good point, although the fact that replay doesn't update refs probably
means I didn't even need to mention these hooks.

_Very_ good point. There should definitely be an option for that,

This stuff really shouldn't have been in the cover letter for this
series, but since it is...

Yep, totally agreed.
But, I really, really want a command that operates in O(changes)
rather than O(repo size), and which can operate on non-checked-out
branches, and even if the user has a dirty working tree.
There are other choices too -- e.g. if replay is fast enough, just
fail if the user has a dirty working tree and tell them to re-issue
the command after first cleaning it up, allowing us to use their
working tree for conflict resolution. However, the level of IDE
thrashing that happens when people check out other branches (and the
subsequent loss of productivity they experience after resolving the
simple conflict and switching back) means I'm not willing to have the
only option be resolving conflicts in the current working tree. I
think something very different than how git-rebase and git-cherry-pick
behave currently are needed, at least as an option.

Sure, some people may need an option to have conflicts be resolved in
the current working tree, or perhaps even in a separate full tree.
But both are such performance killers that an O(changes) option that
doesn't mess with the current working tree is very much needed for
some usecases.
But again, that's **way** outside the scope of this series.

Yeah, that was in patch 9. It should be dropped or have patch 10
squashed into it.
At that point, this series won't contain any ref updating, but will
only have instructions that can be passed to `git update-ref --stdin`.
At that point, no such checks will be necessary for this series (as it
all belongs in `git update-ref --stdin` instead).

I think the choice of what to do for conflicts becomes really complex,
really quick. Just look at git-merge-tree, which is a much simpler
case, and those kinds of questions blocked the series from progressing
for like half a year last year.
I don't think we're ready to answer these questions. In fact, that's
precisely why I never submitted this series, even though I've had the
bits that Christian is pushing in a working state for about 9 months
now.
I think we should defer all conflict handling other than exit status
until later (or continue deferring this series until conflict handling
is ready, but that may be a long time).

And on the client side, it's the one place where I'm almost certainly
going to be forced to accept forking a subprocess, though rest assured
that I'll grumble about it incessantly. :-)

I'm not sure what Christian meant here, but as you say there's
certainly no different special codes in the merge machinery.

The output of `git replay`, with or without these options, is meant to
be passed as input to `git update-refs --stdin`. As such, naming an
option --update-refs for this command just seems inherently confusing.
I also feel like --update-refs is a name coded more around
implementation details than end-user description of behavior (and as
far as implementation details are concerned, this options is not tied
to an interactive backend the way the --update-refs options in rebase
is).
In contrast, --cherry-pick might be reasonable. But I worry it'll be
read backwards by people. I want:
git replay --OPTION branch upstream..commit
to make sense and I worry that OPTION==cherry-pick will cause users to
think `branch` is being cherry-picked rather than `upstream..commit`.
What this command does is advance `branch` by cherry-picking
`upstream..commit` onto it.

Yeah, I was probably wrong to suggest to Christian to use fast-rebase
as the starting point. That is how I started my series, and multiple
people had reviewed it and it seemed like it'd be useful to leverage
that past review, but the reviews of these series so far suggest I may
have made the wrong recommendation to Christian.
