Subject: [PATCH 0/2] rev-list --disk-usage
Date: Wed, 27 Jan 2021 17:11:36 -0500	[thread overview]
Message-ID: <YBHlGPBSJC++CnPy@coredump.intra.peff.net> (raw)

This series teaches rev-list to compute the on-disk size used by a set
of objects. You can do the same thing with cat-file, but this is much
faster (see the timings in the second commit).

We've been running it for about 5 years at GitHub. I hesitated sending
it upstream because it's a bit weird and special-purpose. But it does
come in handy for debugging, analyzing repos, etc. So maybe others will
find it useful.

The first patch is just a test-script enhancement to let test_commit
avoid creating tags. During some recent refactoring, we actually broke
the --disk-usage feature but the test script didn't catch it because the
tags were being picked up by "--all". Since this is at least the third
time I've run into that in our test suite, I thought I'd make it a
little more convenient to avoid. :)

  [1/2]: t: add --no-tag option to test_commit
  [2/2]: rev-list: add --disk-usage option for calculating disk usage
