31 | Make a helper function to check cache damage invariants: | |||
|
|
32 | ||||
|
|
33 | - command output shouldn't change | |||
|
|
34 | - cache should be present after first use | |||
|
|
35 | - corruption/repair should be silent (no exceptions or warnings) | |||
|
|
36 | - cache should survive deletion, overwrite, and append | |||
|
|
37 | - unreadable / unwriteable caches should be ignored | |||
|
|
38 | - cache should be rebuilt after corruption | |||
