|
The dirstate contains the following state:
|
|
|
|
|
|
- `identity` is the identity of the dirstate file, which can be used to
|
|
|
detect when changes have occurred to the dirstate file.
|
|
|
|
|
|
- `parents` is a pair containing the parents of the working copy. The
|
|
|
parents are updated by calling `setparents`.
|
|
|
|
|
|
- the state map maps filenames to tuples of (state, mode, size, mtime),
|
|
|
where state is a single character representing 'normal', 'added',
|
|
|
'removed', or 'merged'. It is read by treating the dirstate as a
|
|
|
dict. File state is updated by calling various methods (see each
|
|
|
documentation for details):
|
|
|
|
|
|
- `reset_state`,
|
|
|
- `set_tracked`
|
|
|
- `set_untracked`
|
|
|
- `set_clean`
|
|
|
- `set_possibly_dirty`
|
|
|
|
|
|
- `copymap` maps destination filenames to their source filename.
|
|
|
|
|
|
The dirstate also provides the following views onto the state:
|
|
|
|
|
|
- `filefoldmap` is a dict mapping normalized filenames to the denormalized
|
|
|
form that they appear as in the dirstate.
|
|
|
|
|
|
- `dirfoldmap` is a dict mapping normalized directory names to the
|
|
|
denormalized form that they appear as in the dirstate.
