Summary: Revset predicates that work substantially through `subset.filter` should have a higher weight than the default value of 1, to prevent the optimizer incorrectly optimizing operations like: ``` reverse(ancestors(node, limit)) & filterpredicate() ``` in a way that filters all the revisions in the repo according the predicate before performing the dag search.

"""
|
|
a revset predicate for filtering by changeset age.
|
|
|
|
Adds the `age()` revset predicate.
|
|
|
|
This revset predicate differs from the built-in `date` by providing a more
|
|
granular way of considering relative time rather than absolute time.
|
|
|
|
The built-in `date()` predicate does provide full day resolution, so
|
|
`age("<Xd")` is equivalent to `date("-X")`.

Similar to ``ancestors(set) & age(agerange)`` except that all ancestors that

excluded. This only matters if there are changesets that have ancestors that

are newer than them.

For example, given the changesets:

|

o aaa (1 hour ago)

o bbb (2 hours ago)

|
|
|

o fff (5 hours ago)

~
|
|
|
|
The expression ``ancestorsaged(aaa, "30m-3h30m")`` would match changesets
|
|
``bbb`` and ``ccc`` only. The changeset ``eee`` is excluded by virtue of
|
|
being an ancestor of ``ddd``, which is outside the age range.

|
The age range can be specified in days, hours, minutes or seconds:
|
|
|
|
- ``<30d`` : Newer than 30 days old

- ``>4h30m``: Older than 4 hours 30 minutes old
