Update "git rev-parse" invocation to work in Git 2.25.0

Authored by epriestley on Jan 16 2020, 7:37 PM.



Fixes T13479. The behavior of "git rev-parse --show-toplevel" has changed in Git 2.25.0, and it now fails in bare repositories.

Instead, use "git rev-parse --git-dir" to sanity-check the working copy. This appears to have more stable behavior across Git versions, although it's a little more complicated for our purposes.

Test Plan
  • Ran bin/repository update ... on an observed, bare repository.
  • ...on an observed, non-bare ("legacy") repository.
  • ...on a hosted, bare repository.
