This is mostly Python 3 compat work thanks to timeless.
crecord: call prevsibling() and nextsibling() directly
The 3 classes for items used in crecord (uiheader, uihunk, uihunkline) all have
prevsibling() and nextsibling() methods. The two methods are used to get the
previous/next item of the same type of the same parent element as the current
one: when `a` is a uihunkline instance, a.nextsibling() returns the next line
in this hunk (or None, if `a` is the last line).
There are also two similar methods: previtem() and nextitem(). When called with
constrainlevel=True (the default) they simply returned the result of
prevsibling()/nextsibling(). Only when called with constrainlevel=False they
did something different: they returned previous/next item regardless of its
type (so if `a` is the last line in a hunk, a.nextitem(constrainlevel=False)
could return the next hunk or the next file -- something that is not a line).
Let's simplify this logic and make code call -sibling() methods when only
siblings are needed and -item() methods when any item would do, and then remove
the constrainlevel argument from previtem() and nextitem().
dispatch: add fail-* family of hooks
The post-* family of hooks will not run in case a command fails (i.e.
raises an exception). This makes it inconvenient to hook into events
such as doing something in case of a failed push.
We catch all exceptions to run the failure hook. I am not sure if this
is too aggressive, but tests apparently pass.
import-checker: recognize relative imports from parents of current package
So far fromlocal recognizes relative imports of the form:
from . import D
from .. import E
It wasn't prepared for recognizing relative imports like:
from ..F import G
The bug was not found so far because all relative imports starting
from the parent was in the list of allowsymbolicimports like:
from ..i18n import
from ..node import
