[outreachy] Walk through the Git history (guix git {authenticate, log})

[zimoun]

Hi,

Discussing how to walk through the Git history
~/.cache/guix/checkouts/<hash>, there is 2 ways to do:

 1. Loop with commit-parents as it is done for ’commit-closure’ in
    guix/git.scm.

 2. Bind git_revwalk_* and use it instead.

WDYT?

Well, #1 is more straightforward but less efficient, IIUC.


All the best,
simon
