In this patch, the documentation says

	Run tasks to optimize Git repository data

the plural is a bit incorrect at this point, but not a huge deal.

The run subcommand says "Run one or more maintenance tasks" which again
is a bit misleading since "or more" is not technically possible. This
becomes a bit obvious when we see that the task list only contains a 'gc'
task.

So no, the documentation in this patch doesn't say "Run the 'gc' task"
because that could be gathered from context _and_ it will be incorrect
by the time this patch is integrated as part of the series.

So I struggle with finding a way to improve the documentation in this
patch to satisfy your concerns. Any change made here will just be un-done
by a later patch in the same series.

I'd rather have something vague now and improve the documentation
incrementally along with the implementation.

Another point you made earlier, but seems to be dropped in this email:
you wanted the return code documented. This also seems like wasteful
text, because the best I can think of is

  This command will return 0 unless a maintenance task failed in an
  unrecoverable way, or other typical failure cases such as incorrect
  usage or the command being run outside of a Git repository.

Please recommend something better, because that description suffers from
being too generic/obvious when talking about the maintenance task and
being an obvious repetition of Git's existing error code behavior.

Perhaps this would be easier if there was an established pattern of
documenting the return code. So, I went digging.

The examples I could find are:

 1. 'git cat-file -e'
 2. 'git check-ref-format'
 3. 'git commit-graph --object-dir=<dir>'
 4. 'git cvsimport'
 5. 'git fast-import'
 6. 'git filter-branch'
 7. 'git grep --quiet'
 8. 'git gui citool'
 9. 'git ls-remote --exit-code'
10. 'git merge-base --is-ancestor'
11. 'git push --recurse-submodules'
12. 'git reflog exists'
13. 'git rev-parse --parseopt'
14. 'git update-index --test-untracked-cache' 

Most of these are for specific options, and the exit code is documented
with relation to how that specific option may lead to a non-zero exit
code (1, 3, 7, 8, 9, 10, 11, 12, 13, 14).

The one that is most clearly part of the main description is for
the plumbing command 'git check-ref-format':

	Checks if a given 'refname' is acceptable, and exits with
	a non-zero status if it is not.

This seems appropriate for something intended for use as a helper
in script, with a very simple behavior. The exit code is the only
way it provides any feedback to the caller! This use of the exit
code as the only output is used by some other cases (1, 7, 9, 10,
11, 12, 13, 14).

Of course, we also have examples like this in git-cvsimport.txt:

	Otherwise, success is indicated the Unix way, i.e. by simply
	exiting with a zero exit status.

This phrase should be _assumed_ as part of Git itself, instead of
written in the documentation for specific commands.

The documentation for 'git fast-import' is more useful here:

	If fast-import is supplied invalid input it will terminate
	with a non-zero exit status and create a crash report...

But, you can see that the exit code is not the focus, but the
crash report _is_ important to document.

'git filter-branch' has a special exit code for the case that no
commits were found to update.

'git gui citool' returns an error code if the window is closed
before the command can complete. This is also not a core feature,
so is not a good example.

My only conclusion from this investigation is that the exit code
is documented when it is useful, but otherwise the standard Unix
pattern is assumed and not worth documenting.

If this is something we want to change, then I don't think it
valuable to have that discussion here. Instead, let's start that
discussion elsewhere with a series that updates existing docs to
catch up to a new standard of documenting the exit code.

You're right. Global is not required. The struct needs to be 'static'
or initialized for compilation.

While trying to get rid of globals based on your recommendation, I
see that the callback functions in the option-parsing _do_ require
global state. This is used in "maintenance: add --task option" with
the global tasks array, but it also uses a global count of "how many
tasks have been selected" currently in the struct. Two ways to get
around that issue include (1) making a global int, or (2) looping
through the task list to count how many have been selected so far.

Neither of these solutions is clean. (In the diff below, I chose
option 2.)

In my opinion, using a global struct would be better than the existing
pattern of a bunch of global variables, but I get your point about
precedence. More on this below.

Using a "singleton" like the opts struct here, the code is definitely
much simpler to read. There is only ever one instance, because the struct
definition comes along with the instance declaration.

By making it a local instance, we then need to pass around the struct as
a parameter to all of the static methods in the builtin, even though there
is only ever one instance of this struct per process.

The two points above are the ones that led me to use the global instance
in the first place.

To get back to your point about being idiomatic, these builtins use a
struct to group options, then pass it around as a parameter:

* cat-file (struct batch_options)
* checkout (struct checkout_opts)
* rebase (struct rebase_options)
* tag (struct create_tag_options)
* worktree (struct add_opts)

Unfortunately, there _is_ an example of the behavior I was following in
this series: my own example in the sparse-checkout builtin. So, I'm just
repeating my own mistakes that were not challenged before.

I updated my v4-in-progress branch with that change, and the tip-to-tip
diff is below. It required some non-trivial care around the --task=<task>
callback (which can't see the local options struct) and other cases.

Thanks,
-Stolee
