bpo-44559: [Enum] restore fixes lost in 3.9 reversion (GH-29114)

- fix exception leaks
- re-add deprecation warnings

bpo-45192: Fix a bug that infers the type of an os.PathLike[bytes] object as str (GH-28323) (GH-29111)

2021-10-20T21:27:30+00:00

An object implementing the os.PathLike protocol can represent a file
system path as a str or bytes object.
Therefore, _infer_return_type function should infer os.PathLike[str]
object as str type and os.PathLike[bytes] object as bytes type.

bpo-39679: Add tests for classmethod/staticmethod singledispatchmethods (GH-29034) (GH-29072)

2021-10-19T22:07:13+00:00

In Python 3.8 and 3.9, stacking `@functools.singledispatchmethod` on top of
`@classmethod` or `@staticmethod` caused an exception to be raised if the
method was registered using type-annotations rather than
`@method.register(int)`. This was not caught by unit tests, however, as the
tests only tested the `@method.register(int)` way of registering additional
implementations. The bug is no longer present in Python 3.10+, but
`test_functools.py` is still lacking regression tests for these cases. This
commit adds these test cases.

[3.10] bpo-45494: Fix parser crash when reporting errors involving invalid continuation characters (GH-28993) (GH-29070)

2021-10-19T20:31:18+00:00

There are two errors that this commit fixes:

* The parser was not correctly computing the offset and the string
  source for E_LINECONT errors due to the incorrect usage of strtok().
* The parser was not correctly unwinding the call stack when a tokenizer
  exception happened in rules involving optionals ('?', [...]) as we
  always make them return valid results by using the comma operator. We
  need to check first if we don't have an error before continuing..

[3.10] bpo-45500: Rewrite test_dbm (GH-29002) (GH-29069)

2021-10-19T20:21:03+00:00

* Generate test classes at import time. It allows to filter them when
  run with unittest. E.g: "./python -m unittest test.test_dbm.TestCase_gnu -v".
* Create a database class in a new directory which will be removed after
  test. It guarantees that all created files and directories be removed
  and will not conflict with other dbm tests.
* Restore dbm._defaultmod after tests. Previously it was set to the last
  dbm module (dbm.dumb) which affected other tests.
* Enable the whichdb test for dbm.dumb.
* Move test_keys to the correct test class. It does not test whichdb().
* Remove some outdated code and comments..

[3.10] bpo-45467: Fix IncrementalDecoder and StreamReader in the "raw-unicode-escape" codec (GH-28944) (GH-28952)

2021-10-14T18:23:39+00:00

They support now splitting escape sequences between input chunks.

Add the third parameter "final" in codecs.raw_unicode_escape_decode().
It is True by default to match the former behavior.
