[PATCH v3 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.

Derrick Stolee (2):
  progress: create GIT_PROGRESS_DELAY
  commit-graph: use start_delayed_progress()

     -    Now that we changed this method, very fast commands show no progess at
     -    all. This means we need to stop testing for seeing these progress lines
     -    in the test suite.
     +    The tests that check for the progress output have already been updated
     +    to use GIT_PROGRESS_DELAY=0 to force the expected output. However, there
     +    is one test in t6500-gc.sh that uses the test_terminal method. This
     +    mechanism does not preserve the GIT_PROGRESS_DELAY environment variable,
     +    so we need to modify check on the output. We still watch for the
     +    "Enumerating objects" progress but no longer look for "Computing
     +    commit graph generation numbers".
