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