Re: 'git submodule update' ignores [http] config

Thanks Jonathan.

The confirmation that the super-project config does not apply to the
submodules is what I was really looking for. We'll go from here.

This is a bit complicated, because this config is all generated
dynamically by the GitLab CI Runner when it is setting up a build job.
(See the linked issue in my first email for the gory details).

Thank you,
Jonathon

I've narrowed it down to an observation that the [http] config seems
to be ignored by 'git submodule update'. Shouldn't those options be
respected by submodules?

Given a .git/config file like this:

------------------------------------------------------------------------
[fetch]
    recurseSubmodules = false
[http "https://gitlab.exmaple.com"]
    sslCAInfo = C:\\Users\\gitlab-runner\\builds\\deadbeef\\0\\somegroup\\someproj.git\\CA_SERVER_TLS_CA_FILE

[...]

quoted

C:\Users\jreinhart\testrepo>set GIT_CURL_VERBOSE=1
C:\Users\jreinhart\testrepo>git fetch

[...]

quoted

*   CAfile: C:\Users\gitlab-runner\builds\deadbeef\0\somegroup\someproj.git\CA_SERVER_TLS_CA_FILE

[...]

quoted

C:\Users\jreinhart\testrepo>git checkout master
C:\Users\jreinhart\testrepo>git submodule update --init

[...]

quoted

*   CAfile: C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt

[...]

Note that the CAfile reverted to its default instead of using the same
one from the `git fetch`.

Interesting.

The context is that "git submodule update" is simply running commands
like "git fetch" inside the submodules, and the repository-local
config of the superproject does not apply there.

In the long run, commands like "git fetch --recurse-submodules" may
chaange to use a single process.  It's possible that some of the
repository-local configuration of the superproject would apply at that
point, though the inconsistency would be confusing, so probably not
these particular settings.  Anyway, that's a faraway future; today,
"git fetch --recurse-submodules" is also running "git fetch" commands
inside the submodules, and the repository-local config of the
superproject does not apply there.

Would it work for you to put this configuration in the global config
file ("git config --global --edit")?  That way, it would be used by
all repositories.  If you want it only to apply within the testrepo
directory, you can use conditional includes --- something like:

  in $HOME/.git/config/testrepo-ca:

  [http "https://gitlab.example.com"]
        sslCAInfo = ...

  in $HOME/.git/config/git:

  [includeIf "gitdir/i:~/testrepo/**"]
        path = testrepo-ca

Thanks and hope that helps,
Jonathan
