[Bug 1347814] Re: git repack -ad can damage a repository that’s partially unreadable by the current user

[Sworddragon]

On retesting this with git 1:2.8.1-1 and the reproduction steps from
comment #5 I'm still getting an error after step 5 but after step 6 the
commits are still there. But now I'm wondering if really nothing got
damaged. Can somebody confirm this?

Title:
  git repack -ad can damage a repository that’s partially unreadable by
  the current user

Status in git package in Ubuntu:
  Confirmed

Bug description:
  I'm using Ubuntu 14.10 dev with git 1:2.0.1-1 and if git-gc hasn't
  full write-access to a repository it can damage it. Getting such a
  permission state for a git repository isn't even unlikely if it was
  optimized in a sudo environment before. Here is an example output:
