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.
