The die() message that may occur in module_name() is not really relevant
to the user when called from module_clone(); the latter handles the
"failure" (no submodule mapping) anyway.

Leave other callers of module_name() unchanged, as the die() message
shown is either relevant for user consumption (such as those that exit()
when the call fails), or will not occur at all (when called with paths
returned by module_list()).

As these are the only lines where spaces are used for indentation in this
file this might be a worthwhile cleanup, but I really don't care that much.
Junio, what do you think?

BTW: this patch applies to next

Makes tons of sense, especially as adding a new submodule currently always
spews out the "No submodule mapping found in .gitmodules for path 'sub'"
message right before that mapping is added there. Thanks for noticing that
and ACK on that change from my side.

Hmm, while I agree on the first reasoning I'm not sure about the second.
module_list() asks the index for the submodule paths while module_name()
gets it's input from .gitmodules, so they can (and sometimes will)
disagree. When cmd_foreach() passes an empty "name" variable to the
spawned command that might still work (and even make sense), but using the
empty name in cmd_sync() to access the config is looking like an error to
me. It might make sense to add an "|| exit" at least to the callsite in
cmd_sync(). Or am I missing something here?

Thanks for the review.

Oh, you're right. I neglected to see how module_list() actually worked.

When cmd_foreach() passes an empty "name" variable to the
spawned command that might still work (and even make sense), but using the
empty name in cmd_sync() to access the config is looking like an error to
me. It might make sense to add an "|| exit" at least to the callsite in

Cc-ed David, who authored cmd_sync().

David, what do you think of Jens' analysis?

In the meantime, I'll probably reword the second paragraph to say that
future work will be needed to analyze non- || exit callsites.

Yeah, me too thinks the missing "|| exit" should be subject of another
patch.

Junio, this goes on top of 'fg/submodule-git-file-git-dir' (particularly
the second patch).

Changed in v2: reworded 2nd paragraph of 2nd patch, as recommended by
Jens.

Analysis of other callsites is left to future work.
