[PATCH v4 0/2] commit-graph: use start_delayed_progress()

Thanks, Ryenus, for reporting this problem.

Update in V3:

Based on our discussion, I've added the suggested GIT_PROGRESS_DELAY environment variable. This allowed the existing tests to stick around with one exception in the GC tests. The test remains, but we can no longer look at the commit-graph output.

Update in V4:

The GIT_PROGRESS_DELAY check is extracted to a helper method so it can be used with start_delayed_sparse_progress().

  progress: create GIT_PROGRESS_DELAY
  commit-graph: use start_delayed_progress()
