|
1439 | 1452 | - `identity` is the identity of the dirstate file, which can be used to |
|
1440 | 1453 | detect when changes have occurred to the dirstate file. |
|
1441 | 1454 | |
|
1442 | 1455 | - `parents` is a pair containing the parents of the working copy. The |
|
1443 | 1456 | parents are updated by calling `setparents`. |
|
1444 | 1457 | |
|
1445 | 1458 | - the state map maps filenames to tuples of (state, mode, size, mtime), |
|
1446 | 1459 | where state is a single character representing 'normal', 'added', |
|
1447 | 1460 | 'removed', or 'merged'. It is read by treating the dirstate as a |
|
1448 | 1461 | dict. File state is updated by calling the `addfile`, `removefile` and |
|
1449 | 1462 | `dropfile` methods. |
|
1450 | 1463 | |
|
1451 | 1464 | - `copymap` maps destination filenames to their source filename. |
|
1452 | 1465 | |
|
1453 | 1466 | The dirstate also provides the following views onto the state: |
|
1454 | 1467 | |
|
1455 | 1468 | - `nonnormalset` is a set of the filenames that have state other |
|
1456 | 1469 | than 'normal', or are normal but have an mtime of -1 ('normallookup'). |
|
1457 | 1470 | |
|
1458 | 1471 | - `otherparentset` is a set of the filenames that are marked as coming |
|
1459 | 1472 | from the second parent when the dirstate is currently being merged. |
|
1460 | 1473 | |
|
1461 | 1474 | - `filefoldmap` is a dict mapping normalized filenames to the denormalized |
|
1462 | 1475 | form that they appear as in the dirstate. |
|
1463 | 1476 | |
