bpo-45198: __set_name__ documentation not clear about its usage with non-descriptor classes (GH-28439)

2021-09-18T06:49:43+00:00

bpo-44990: Change layout of evaluation frames. "Layout B" (GH-27933)

2021-08-25T12:44:20+00:00

Places the locals between the specials and stack. This is the more "natural" layout for a C struct, makes the code simpler and gives a slight speedup (~1%)

bpo-42035: Add PyType_GetQualName() to get a type's qualified name. (GH-27551)

2021-08-17T13:39:34+00:00

bpo-44914: Maintain invariants of type version tags. (GH-27773)

2021-08-16T11:21:34+00:00

* Do not invalidate type versions unnecessarily.

bpo-44821: Eagerly assign dict for new objects. (GH-27589)

2021-08-04T15:41:14+00:00

bpo-42035: Add a PyType_GetName() to get type's short name. (GH-23903)

2021-07-29T07:57:02+00:00

bpo-44590: Lazily allocate frame objects (GH-27077)

2021-07-26T10:22:16+00:00

* Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it.

* Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector.

* Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation.

* Move ownership of InterpreterFrame in generator from frame object to generator object.

* Do not create frame objects for Python calls.

* Do not create frame objects for generators.

bpo-42747: Remove Py_TPFLAGS_HAVE_AM_SEND and make Py_TPFLAGS_HAVE_VERSION_TAG no-op (GH-27260)

2021-07-23T13:21:11+00:00

* Remove code that checks Py_TPFLAGS_HAVE_VERSION_TAG
    
    The field is always present in the type struct, as explained
    in the added comment.

* Remove Py_TPFLAGS_HAVE_AM_SEND
    
    The flag is not needed, and since it was added in 3.10 it can be removed now.

bpo-44654: Refactor and clean up the union type implementation (GH-27196)

2021-07-17T19:44:10+00:00

bpo-44184: Apply GH-26274 to the non-GC-type branch of subtype_dealloc (GH-27165)

2021-07-15T22:40:57+00:00

The non-GC-type branch of subtype_dealloc is using the type of an object after freeing in the same unsafe way as GH-26274 fixes. (I believe the old news entry covers this change well enough.)
