"""A structure to store and serialize/deserialize replay-related data
|
|
|
|
Replay is a process of re-application of an `unbundle`, captured on
|
|
the wire in some other system. Such re-application might have some
|
|
expectations, which we need to be able to verify, and some additional
|
|
data, which we may need to use. Currently, the following are stored:
|
|
`commitdates` - a map form the original hash to the commit date to
|
|
be used in a rebased commit. Must be in the format,
|
|
understood by `util.parsedate`.
|
|
- `ontobook` - a bookmark, used for pushrebase
|
|
- `rebasedhead`- an expected hash of the rebased head
