Code Issues Releases Wiki Activity

Use execxLocal() for ArcanistGitAPI

Browse source 
Summary:
  - This is simpler and reuses more code than doing "(cd %s && ...)" every time.
  - If we have an issue like HGPLAIN, we have one place to fix it now.
  - On Windows, the construct "(cd %s && ...)" does not mean what we'd like it to.

Test Plan: Ran "arc diff" in a git repo with this change.
