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.
