* syslog_get_argv() swallows exceptions, but not in all cases.
* if ident is non UTF-8 encodable, syslog.openlog() fails after setting the
global reference to ident. Now the C string saved internally in the previous
call to openlog() points to the freed memory.
* PySys_Audit() can crash if ident is NULL.
* There may be a race condition with syslog.syslog(), because the global
reference to ident is decrefed before setting the new value.
* Possible use of freed memory if syslog.openlog() is called while
the GIL is released in syslog.syslog().
* Add _Py_memory_repeat function to pycore_list
* Add _Py_RefcntAdd function to pycore_object
* Use the new functions in tuplerepeat, list_repeat, and list_inplace_repeat
Static builtin types are finalized by calling _PyStaticType_Dealloc(). Before this change, we were skipping finalizing such a type if it still had subtypes (i.e. its tp_subclasses hadn't been cleared yet). The problem is that types hold several heap objects, which leak if we skip the type's finalization. This change addresses that.
For context, there's an old comment (from e9e3eab0b8) that says the following:
// If a type still has subtypes, it cannot be deallocated.
// A subtype can inherit attributes and methods of its parent type,
// and a type must no longer be used once it's deallocated.
However, it isn't clear that is actually still true. Clearing tp_dict should mean it isn't a problem.
Furthermore, the only subtypes that might still be around come from extension modules that didn't clean them up when unloaded (i.e. extensions that do not implement multi-phase initialization, AKA PEP 489). Those objects are already leaking, so this change doesn't change anything in that regard. Instead, this change means more objects gets cleaned up that before.
This is the first of several precursors to storing tp_subclasses (and tp_weaklist) on the interpreter state for static builtin types.
We do the following:
* add `_PyStaticType_InitBuiltin()`
* add `_Py_TPFLAGS_STATIC_BUILTIN`
* set it on all static builtin types in `_PyStaticType_InitBuiltin()`
* shuffle some code around to be able to use _PyStaticType_InitBuiltin()
* rename `_PyStructSequence_InitType()` to `_PyStructSequence_InitBuiltinWithFlags()`
* add `_PyStructSequence_InitBuiltin()`.
* gh-95218: Move tests for importlib.resources into test_importlib.resources.
* Also update makefile
* Include test_importlib/resources in code ownership rule.
This PR partially reverts gh-24421 (PR) and fixes the remaining concerns
given in gh-93044 (issue):
- keyword arguments are passed as positional arguments to factory()
- if an argument is not passed to sqlite3.connect(), its default value
is passed to factory()

The Issue templates are using the markup to make text bold.
We should be using proper text headers instead.
I replaced the **bold** text markup with L1 headers.
This appears to be a typo. It causes try_protocol_combo to try to turn
on SSL 3.0 when testing PROTOCOL_SSLv23 (aka PROTOCOL_TLS), which
doesn't make any sense. Fix it to be PROTOCOL_SSLv3.
Without this, try_protocol_combo is actually setting
context.minimum_version to SSLv3 when called as
try_protocol_combo(ssl.PROTOCOL_TLS, ssl.PROTOCOL_TLS, True)
One would think this causes a no-ssl3 OpenSSL build to fail, but OpenSSL
forgot to make SSL_CTX_set_min_proto_version(SSL3_VERSION) does not
notice no-ssl3, so this typo has gone undetected. But we should still
fix the typo because, presumably, a future version of OpenSSL will
remove SSL 3.0 and do so more thoroughly, at which point this will
break.
