bpo-45200: GHA Address Sanitizer skips 3 slowest tests (GH-30797)

2022-01-22T18:15:37+00:00

Skip the 3 slowest tests of the Address Sanitizer CI of GitHub
Actions:

* test_tools
* test_peg_generator
* test_concurrent_futures

These tests take between 5 and 20 minutes on this CI which makes this
CI job the slowest. Making this CI job faster makes the whole Python
workflow faster. These tests are run on all others CIs.

Example of Address Sanitizer output:

    10 slowest tests:
    - test_peg_generator: 17 min 33 sec
    - test_tools: 8 min 27 sec
    - test_concurrent_futures: 5 min 24 sec
    - test_zipfile: 2 min 41 sec
    - test_compileall: 2 min 21 sec
    - test_asyncio: 2 min 17 sec
    - test_gdb: 1 min 43 sec
    - test_weakref: 1 min 35 sec
    - test_pickle: 1 min 18 sec
    - test_subprocess: 1 min 12 sec

Moreover, test_concurrent_futures also seems to be affected by
bpo-45200 bug: libasan dead lock in pthread_create().

bpo-46417: Cleanup typeobject.c code (GH-30795)

2022-01-22T17:56:11+00:00

* Add comment to recurse_down_subclasses() explaining why it's safe
  to use a borrowed reference to tp_subclasses.
* remove_all_subclasses() no longer accept NULL cases
* type_set_bases() now relies on the fact that new_bases is not NULL.
* type_dealloc_common() avoids PyErr_Fetch/PyErr_Restore if tp_bases
  is NULL.
* remove_all_subclasses() makes sure that no exception is raised.
* Don't test at runtime if tp_mro only contains types: rely on
  _PyType_CAST() assertion for that.
* _PyStaticType_Dealloc() no longer clears tp_subclasses which is
  already NULL.
* mro_hierarchy() avoids calling _PyType_GetSubclasses() if
  tp_subclasses is NULL.

Coding style:

* Use Py_NewRef().
* Add braces and move variable declarations to the first variable
  assignement.
* Rename a few variables and parameters to use better names.

bpo-46417: Clear more static types (GH-30796)

2022-01-22T17:55:48+00:00

* Move PyContext static types into object.c static_types list.
* Rename PyContextTokenMissing_Type to _PyContextTokenMissing_Type
  and declare it in pycore_context.h.
* _PyHamtItems types are no long exported: replace PyAPI_DATA() with
  extern.
