This is something I noticed while (now discontinued) experimenting
with the idea of annotating operators with location information. Unfortunately
without this addition, adding any `attributes` to stuff like `unaryop`
doesn't change anything since the code assumes they are singletons and
caches all instances. This patch fixes this assumption with including
the attributes as well as constructor fields.
* Issue a deprecation warning on smtpd import
* Also issue DeprecationWarnings for asynchat and asyncore
* Fix some tests
* test___all__ requires the word 'module' or 'package' in the deprecation
warning text, so add those to smtpd, asynchat, and asyncore.
* In test_support, use pprint now instead of asyncore as the landmark.
* Add What's New
* Use ..deprecated::
* Use ..deprecated::
* Update Lib/smtpd.py

I tried to be relatively thorough and give lots of links.
One reason is that this wasn't deprecated very long; also it seems people running into this tend to not be familiar with similar APIs.

Remove 4 C API private trashcan functions which were only kept for
the backward compatibility of the stable ABI with Python 3.8 and
older, since the trashcan API was not usable with the limited C API
on Python 3.8 and older. The trashcan API was excluded from the
limited C API in Python 3.9.
Removed functions:
* _PyTrash_deposit_object()
* _PyTrash_destroy_chain()
* _PyTrash_thread_deposit_object()
* _PyTrash_thread_destroy_chain()
The trashcan C API was never usable with the limited C API, since old
trashcan macros accessed directly PyThreadState members like
"_tstate->trash_delete_nesting", whereas the PyThreadState structure
is opaque in the limited C API.
Exclude also the PyTrash_UNWIND_LEVEL constant from the C API.
The trashcan C API was modified in Python 3.9 by commit
38965ec541 and in Python 3.10 by commit
ed1a5a5bac to hide implementation
details.
PyModuleDef_Init() no longer tries to make PyModule_Type type: it's
already done by _PyTypes_Init() at Python startup. Replace
PyType_Ready() call with an assertion.
Py_RunMain() now resets PyImport_Inittab to its initial value at
exit. It must be possible to call PyImport_AppendInittab() or
PyImport_ExtendInittab() at each Python initialization.
ASDL Generator was lack of proper annotation related to generated
module. This patch implements a MetadataVisitor that produces a
metadata object to pass to other visitors that are visiting that
same module. For the inital patch, it dynamically retrieves int
sequences (like cmpop), that was previously hardcoded. It offers
an interface that is easy to extend.
Fix asyncio test_popen() of test_windows_utils by using a longer
timeout. Use military grade battle-tested test.support.SHORT_TIMEOUT
timeout rather than a hardcoded timeout of 10 seconds: it's 30
seconds by default, but it is made longer on slow buildbots.
WaitForMultipleObjects() timeout argument is in milliseconds.
_thread.start_new_thread() no longer calls PyThread_exit_thread()
explicitly at the thread exit, the call was redundant.
On Linux with the glibc, pthread_cancel() loads dynamically the
libgcc_s.so.1 library. dlopen() can fail if there is no more
available file descriptor to open the file. In this case, the process
aborts with the error message:
"libgcc_s.so.1 must be installed for pthread_cancel to work"
pthread_cancel() unwinds back to the thread's wrapping function that
calls the thread entry point.
The unwind function is dynamically loaded from the libgcc_s library
since it is tightly coupled to the C compiler (GCC). The unwinder
depends on DWARF, the compiler generates DWARF, so the unwinder
belongs to the compiler.
Thanks Florian Weimer and Carlos O'Donell for their help on
investigating this issue.
* Specialize obj.__class__ with LOAD_ATTR_SLOT
* Specialize instance attribute lookup with attribute on class, provided attribute on class is not an overriding descriptor.
* Add stat for how many times the unquickened instruction has executed.
