* gh-93353: Fix importlib.resources._tempfile() finalizer (GH-93377)Miss Islington (bot)2022-06-131-2/+5
| | | | | | | | Fix the importlib.resources.as_file() context manager to remove the temporary file if destroyed late during Python finalization: keep a local reference to the os.remove() function. Patch by Victor Stinner. (cherry picked from commit 443ca731d6b1267fe2f92985e0490460c95e44a8) Co-authored-by: Victor Stinner <vstinner@python.org>

| | | | | (cherry picked from commit b1e286860742e7ba6fadc75e3ddb6c2899a56919) Co-authored-by: Jason R. Coombs <jaraco@jaraco.com>
* bpo-46246: add missing __slots__ to importlib.metadata.DeprecatedList (GH-30452)Miss Islington (bot)2022-02-111-0/+2
| | | | | | | | | | Confirmed with @jaraco that this indeed needs a fix. A question that came up while I was digging into the code: I think `SelectableGroups` could similarly use `__slots__ = ()`, since its purpose seems only for convenience around `dict`, not to have attributes of its own.
