[issue41271] Add support for io_uring to cpython

Ronald Oussoren added the comment: How stable is the io_uring API? The stdlib evolves slowly, I'm not sure if the io_uring interface has matured enough to make it acceptable that updates to the stdlib bindings for that API are only done in new major releases of CPython (about every 18

[issue41291] Race conditions when opening and deleting a file on Mac OS X

Ronald Oussoren added the comment: I've attached a variation on test-conc-read.py that uses os.open and low-level APIs instead of the Python IO stack (open/io.open). This fails in the same way. os.open/os.read/os.write/os.close are very thin wrappers around the corresponding C APIs. That

[issue41271] Add support for io_uring to cpython

Benjamin Peterson added the comment: I agree that adding stdlib support is premature. io_uring has a large and growing API surface. It will take some experimentation to see what the best way to expose its power to Python is. -- nosy: +benjamin.peterson

Yury Selivanov added the comment: > Im interested in learning about the new api. There are two problems with the current API: 1. Reader and writer are separate objects, while they should be one. 2. Writer.write is not a coroutine, although it should be one. There are other minor nits, but
