   3test_description='Test operations that emphasize the delta base cache.
   4
   5We look at both "log --raw", which should put only trees into the delta cache,
   6and "log -Sfoo --raw", which should look at both trees and blobs.
   7
   8Any effects will be emphasized if the test repository is fully packed (loose
   9objects obviously do not use the delta base cache at all). It is also
  10emphasized if the pack has long delta chains (e.g., as produced by "gc
  11--aggressive"), though cache is still quite noticeable even with the default
  12depth of 50.
  13
  14The setting of core.deltaBaseCacheLimit in the source repository is also
  15relevant (depending on the size of your test repo), so be sure it is consistent
  16between runs.
