  • In what ways are channels are better than the traditional await?

    Incidentally, the alternative event loop implementation trio in python does not have "gather", you also need channels, and it's a deliberate design choice - there is some discussion about that in this ticket

  • The Heisenbug lurking in your async code (Python)

    I'll +1 the Trio shoutout [1], but it's worth emphasizing that the core concept of Trio (nurseries) now exists in the stdlib in the form of task groups [2]. The article mentions this very briefly, but it's easy to miss, and I wouldn't describe it as a solution to this bug, anyways. Rather, it's more of a different way of writing multitasking code, which happens to make this class of bug impossible.



  • The gotcha of unhandled promise rejections
    5 projects | | 13 Jan 2023
    It's similar to manual memory management.

    Structured concurrency is one approach to solving this problem. In a structured concurrency a promise would not go out of scope unhandled. Not sure how you would add APIs for it though.

    See Python's trio nurseries idea which uses a python context manager.

    I'm working on a syntax for state machines and it could be used as a DSL for promises. It looks similar to a bash pipeline but it matches predicates similar to prolog.

    In theory you could wire up a tree of structured concurrency with this DSL.

  • Python Asyncio: The Complete Guide

    Not complete - doesn't include Task Groups [1]

    In fairness they were only included in asyncio as of Python 3.11, which was released a couple of weeks ago.

    These were an idea originally from Trio [2] where they're called "nurseries" instead of "task groups". My view is that you're better off using Trio, or at least anyio [3] which gives a Trio-like interface to asyncio. One particularly nice thing about Trio (and anyio) is that there's no way to spawn background tasks except to use task groups i.e. there's no analogue of asyncio's create_task() function. That is good because it guarantees that no task is ever left accidentally running in the background and no exception left silently uncaught.
