Re: [PATCH 1/1][RFC][GSoC] submodule: using 'is_writing_gitmodules_ok()' for a stricter check

[Shourya Shukla <shouryashukla.oo@gmail.com>]

Hello Johannes,

I understand your point of view here. What I am trying to say is that we must update
our .gitmodules if atleast the function 'is_writing_gitmodules_ok()' passes.

Before, we used to pass the if condition if our .gitmomdules existed and it did not matter
if there were any traces of it in the index.

> But we're in the function called `update_path_in_gitmodules()` which

But we still originally(before my patch) checked for the existence of .gitmodules right?
The functions exits with error in case of absence of the file(which should happen).

> So I do not think that we can proceed if `.gitmodules` is absent from

Yes that is one case, but the other case is that _if_ the file exists, it **should** not
exist in the index or our current branch(which must be necessary to ensure before making
any updates to the file right?). This is the case which was not covered before but I have
tried to cover it in my patch.

Is this explanation correct?
