Χρήστος Γεωργίου (Christos Georgiou) <t...@users.sourceforge.net> added the
comment:
An explanation to the changes.
The old code kept the operator.itemgetter arguments in the ag->attr member. If
the argument count (ag->nattrs) was 1, the single argument was kept; if more
than 1, a tuple of the original arguments was kept.
On every attrgetter_call call, if ag->nattrs was 1, dotted_getattr was called
with the plain ag->attr as attribute name; if > 2, dotted_getattr was called
for every one of the original arguments.
Now, ag->attr is always a tuple, containing either dotless strings or tuples of
dotless strings:
operator.attrgetter("name1", "name2.name3", "name4")
stores ("name1", ("name2", "name3"), "name4") in ag->attr.
dotted_getattr accordingly chooses based on type (either str or tuple, ensured
by attrgetter_new) whether to do a single access or a recursive one.
