* gh-117482: Simplify the Fix For Builtin Types Slot Wrappers (GH-122865)Eric Snow2024-09-093-12/+1
| | | | | | | | | | | | | | | | | 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.)

* gh-122311: Improve and unify pickle errors (GH-122771)Serhiy Storchaka2024-09-092-149/+154
| | | | | | | | | | | | | * 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.

* gh-120221: Support KeyboardInterrupt in asyncio REPL (#123795)Łukasz Langa2024-09-067-21/+131
| | | | | | | | | 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.

| | | | | | | | | | | known browser (GH-113011) When checking if the registering browser is the "OS preferred browser", do not use a substring search - that makes no sense: one can have a preferred browser that looks like a super-string of a known browser, e.g. "firefox-nightly" vs "firefox". https://github.com/python/cpython/issues/108172 explains in more detail, and lays out a potential better future enhancement for this case of just using xdg-open. We'll go with this for now. --------- Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>
