99 | This cache is used to avoid costly computations to determine all the | |||

|
101 | ||||
|
102 | The cache is serialized on disk in the following format: | |||
|
103 | ||||
|
104 | <tip hex node> <tip rev number> [optional filtered repo hex hash] | |||
|
105 | <branch head hex node> <branch name> | |||
|
106 | <branch head hex node> <branch name> | |||
|
107 | ... | |||
|
108 | ||||
|
109 | The first line is used to check if the cache is still valid. If the | |||
|
110 | branch cache is for a filtered repo view, an optional third hash is | |||
|
111 | included that hashes the hashes of all filtered revisions. | |||
