Using git below version 2.7 requires remote (e.g. GitHub) credentials on every run (for private repos)

Summary

When Streamlit uses Git to detect branch/remote information. It uses GitPython package to

Steps to reproduce

What are the steps we should take to reproduce the bug:

1. Install an old version of git (< 2.7)
2. Create/run a streamlit script on a private repo

Expected behavior:

No credentials should be asked for.

Actual behavior:

You should see credentials being asked for (and asked on every rerun).

Is this a regression?

yes - because we never required gitpython in the past.

Debug info

• Streamlit version: 0.68+

Can also just log that git is pretty old.

Please add an option to disable git requests altogether. I am forcing page reload when new data arrives (session.request_rerun), about once a second, and see

2020-11-16 14:15:14 frap git.cmd[279370] DEBUG Popen(['git', 'rev-parse', '--show-toplevel'], cwd=/some/path, universal_newlines=False, shell=None, istream=None)

at every reload. This means spawning two processes every second.

Hi @kmcgrady

I have (*had) GitPython==2.0.6

I tried upgrading it to GitPython==3.1.13 and this solved the issue.

Thanks for the advice, this was a major pain point for me.
