I don't think it's so bad if the pathspec is cleaned up just after it is used,
the diff below applies on top of your patch - see what you think. The diff
also adds dies if --all is given with --pathspec-from-file which (together
with a test) would be worth adding to you series I think.
Unfortunately, your reply came too late, topic was cooking in pu/next
for a while and merged into master yesterday: c58ae96f.
I understand that your patch consists of two parts:
1) Adding test for --all
------------------------
I must admit that I overlooked that there was a similar test for
args-based pathspec. I will add this part in my next topic for
--pathspec-from-file. I expect it to appear in the next day or two. I
will try to remember to CC you to it.
2) Moving parsing/validation into `parse_and_validate_options()`
------------------------
Again, I agree that having parsing/validation outside is suboptimal.
However, with current code, I find it to be a choice between two evils,
and my choice was "outside but clear" to "inside but obscure".
What I find obscure in your suggestion/patch is that innocently looking
`prepare_index()` suddenly clears pathspec as well. It's even harder to
see when called through `dry_run_commit()`.
Now, let me illustrate. There's a similar case in my TODO list, this
time involving a real bug in git. In `init_db()`, the bug occurs in
`set_git_dir(real_path(git_dir))`, also due to unexpected clearing.
Now that I pointed my finger at it, please try to find what's wrong. I
imagine that it won't be easy at all. And it's way harder when there's
no reason to dig deep into a very specific line of code.
I really try to avoid such type of pitfalls. That's why my choice
between two evils is what I did.
