[issue46841] Inline bytecode caches

Mark Shannon added the comment: We need to decide what to do about dis. I don't think we should have a `show_cache` option, as the caches are meaningless junk without quickening (maybe we should drop the CACHE opcode, and just use zeroes). Instead we should have a `show_quickened` option, t

Safihre added the comment: Could the new PR be reviewed? Thank you! https://github.com/python/cpython/pull/31492 Documentation still needs updating, but would like feedback. PS: Why not enable the setting the GitHub Actions workflow only need to be approved for new GitHub accounts instead of

[issue46844] Context-based TaskGroup for legacy libraries

Andrew Svetlov added the comment: I personally don't think that the described opt-in trick should be a part of asyncio. A third-party library that patches asyncio.create_task() can be a useful thing though during the transition period. We even cannot deprecate asyncio.create_task() right now:

[issue46847] functools.update_wrapper doesn't understand partial objects and annotations

New submission from Larry Hastings : functools.update_wrapper currently copies over every attribute listed in the "assigned" parameter, which defaults to WRAPPER_ASSIGNMENTS, which means it copies the wrapped function's __annotations__ to the wrapper. This is slightly wrong if the wrapper oc

[issue46846] functools.partial objects should set __signature__ and _annotations__

New submission from Larry Hastings : I ran across an interesting bug in issue #46761. If you call functools.update_wrapper on a functools.partial object, inspect.signature will return the wrong (original) signature for the partial object. We're still figuring that one out. And, of course, i

[issue46761] functools.update_wrapper breaks the signature of functools.partial objects

Larry Hastings added the comment: Okay, so, I considered the problem for a while, and I have a reasonable theory about what follow_wrapper_chains was for in the first place. If you have a generic decorator, like functools.cache(), it usually looks like this: def my_decorator(fn): def

Kumar Aditya added the comment: > Okay, let's change the error handling. @Kumar, can you handle that? How it should be handled? Currently PyUnicode_InternInPlace ignores any errors and does not return it. It would be backwards-incompatible to change that, moreover as I explained in https://
