[PATCHv3 00/23] Bring more repository handles into our code base

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This resends origin/sb/more-repo-in-api.

Unlike the previous resend (v2), this is not rebased to a newer base.
This doesn't contain the patch for pending semantic changes, as that
seems to go in its own topic branch.

Please have a look at the last 4 patches specifically as they were new in
the last iteration (but did not receive any comment), as they demonstrate
and fix a problem that is only exposed when using GIT_TEST_COMMIT_GRAPH=1
for the test suite.

Thanks,
