1a2e438a9c666381c57cb974ff77f0ba836186dc can traverse `asyncio.shield`, i.e. show what's behind the shield that's blocking a given task. This ticket is to explicitly show `shield` as an element in the task traceback or...
Event loop maintains a set of sockets that are being waited for with callbacks. It should be possible to figure out which task is waiting for which socket. Sockets could...
`asyncio.wait` is similar to `asyncio.gather` but supports more functionality: `return_when` (operation mode) can be "first completed" "first exception" or "all completed". we should report the operation mode and what's still...
It seem that setting context variables in `on_startup` is not supported. My naïve understanding is that there needs to be a new (copied) context in which all of `on_startup`, asgi...
TL;DR let's *not* make it about GIL. Let's call it free-threading or multicore enhancements. I'm for one tired of GIL-flame. (Assume devil's advocate mode) I'd posit that Python has only...
Perhaps gilectomy could learn from databases? https://en.wikipedia.org/wiki/Two-phase_locking has a thorough description and a nice diagram. Perhaps a sensible trade-off could be picked there?
Linux kernel switched from spinlocks to seqlocks to RCU. Perhaps there's a parallel with Python containers, at least. If two threads want to expand dict storage, perhaps it doesn't matter...
"hotspot bias locks" text presents an explanation why CAS is typically fast (doesn't require bus activity if this CPU has the value in a cache line in M state). Perhaps...
For example: ``` In [1]: import asyncio In [2]: l = asyncio.Lock() In [7]: %await_ l # OK In [8]: %await_ l # waits forever, since lock is already taken,...
