The merge state is stored on disk when needed. Two files are used: one with
an old format (version 1), and one with a new format (version 2). Version 2
stores a superset of the data in version 1, including new kinds of records
in the future. For more about the new format, see the documentation for
`_readrecordsv2`.
Each record can contain arbitrary content, and has an associated type. This
`type` should be a letter. If `type` is uppercase, the record is mandatory:
versions of Mercurial that don't support it should abort. If `type` is
lowercase, the record can be safely ignored.
Currently known records:
L: the node of the "local" part of the merge (hexified version)
O: the node of the "other" part of the merge (hexified version)
F: a file to be merged entry
C: a change/delete or delete/change conflict
P: a path conflict (file vs directory)
f: a (filename, dictionary) tuple of optional values for a given file
l: the labels for the parts of the merge.
Merge record states (stored in self._state, indexed by filename):
u: unresolved conflict
r: resolved conflict
pu: unresolved path conflict (file conflicts with directory)
pr: resolved path conflict
o: file was merged in favor of other parent of merge (DEPRECATED)
The resolve command transitions between 'u' and 'r' for conflicts and
'pu' and 'pr' for path conflicts.
