In gh-121602, I applied a fix to a builtin types initialization bug.
That fix made sense in the context of some broader future changes,
but introduced a little bit of extra complexity. That fix has turned
out to be incomplete for some of the builtin types we haven't
been testing. I found that out while improving the tests.
A while back, @markshannon suggested a simpler fix that doesn't
have that problem, which I've already applied to 3.12 and 3.13.
I'm switching to that here. Given the potential long-term
benefits of the more complex (but still incomplete) approach,
I'll circle back to it in the future, particularly after I've improved
the tests so no corner cases slip through the cracks.
(This is effectively a "forward-port" of 716c677 from 3.13.)
* Raise PicklingError instead of UnicodeEncodeError, ValueError
and AttributeError in both implementations.
* Chain the original exception to the pickle-specific one as __context__.
* Include the error message of ImportError and some AttributeError in
the PicklingError error message.
* Unify error messages between Python and C implementations.
* Refer to documented __reduce__ and __newobj__ callables instead of
internal methods (e.g. save_reduce()) or pickle opcodes (e.g. NEWOBJ).
* Include more details in error messages (what expected, what got).
* Avoid including a potentially long repr of an arbitrary object in
error messages.
This switches the main pyrepl event loop to always be non-blocking so that it
can listen to incoming interruptions from other threads.
This also resolves invalid display of exceptions from other threads
(gh-123178).
This also fixes freezes with pasting and an active input hook.
Use a `PyMutex` to avoid the race in mutex initialization. Use relaxed
atomics to avoid the data race on reading `_PyOS_ReadlineTState` when
checking for re-entrant calls.
Setting dev_mode to 1 in an isolated configuration now enables also
faulthandler.
Moreover, setting "module_search_paths" option with
PyInitConfig_SetStrList() now sets "module_search_paths_set" to 1.
Add PyConfig_Get(), PyConfig_GetInt(), PyConfig_Set() and
PyConfig_Names() functions to get and set the current runtime Python
configuration.
Add visibility and "sys spec" to config and preconfig specifications.
_PyConfig_AsDict() now converts PyConfig.xoptions as a dictionary.

* urljoin() with relative reference "?" sets empty query and removes fragment.
* Preserve empty components (authority, params, query, fragment) in urljoin().
* Preserve empty components (authority, params, query) in urldefrag().
Also refactor the code and get rid of double _coerce_args() and
_coerce_result() calls in urljoin(), urldefrag(), urlparse() and
urlunparse().
This checks are redundant in normal circumstances and can only work if
the extension registry was intentionally broken.
* The Python implementation now raises exception for the extension code
with false boolean value.
* Simplify the C code. RuntimeError is now raised in explicit checks.
* Add many tests.
