Jeffrey04<a href="https://kitfucoda.medium.com/writing-a-telegram-bot-in-python-866972ab63f5" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://kitfucoda.medium.com/writing-a-telegram-bot-in-python-866972ab63f5</a>I've just finished writing up a deep dive into building a Telegram bot with a FastAPI web application, and it was quite the journey into asynchronous Python! 🐍The project started with a desire to run chatbots across multiple platforms, but quickly evolved into a focused exploration of asyncio. I found myself wrestling with event loops, queues, and the nuances of asyncio.create_task vs. asyncio.to_thread. It became very clear that understanding the difference between concurrency and parallelism is absolutely crucial in this space. Clever scheduling can mitigate blocking, but over-scheduling will inevitably lead to performance issues.Architectural considerations became a major focus. I learned firsthand that cramming everything into a single process, while tempting, isn't always the best approach. Separating processes for scalability and future enhancements is something I'll definitely keep in mind for future projects.This project was a great learning experience, and I'm looking forward to applying these lessons to future projects. If you're interested in asyncio, webhooks, or building chatbots, I'd love to hear your thoughts! <a href="https://hachyderm.io/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> <a href="https://hachyderm.io/tags/asyncio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#asyncio</a> <a href="https://hachyderm.io/tags/telegrambot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#telegrambot</a> <a href="https://hachyderm.io/tags/fastapi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fastapi</a> <a href="https://hachyderm.io/tags/webdevelopment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#webdevelopment</a> <a href="https://hachyderm.io/tags/programming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#programming</a> <a href="https://hachyderm.io/tags/opentowork" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opentowork</a> <a href="https://hachyderm.io/tags/fedihire" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fedihire</a>

I want to be able to copy entire filesystem trees while tracking and displaying progress and not code this by hand.Edit: I'll also accept D-Bus APIs like Udisks2, but Udisks2 doesn't seem to provide this feature.Edit 2: anything like an easy-to-use wrapper around something like rsync is fine too, as long as I still get to track and report progress.

Sijmen MulderTo me it seems that user-level threads (like async in C#) and system-level threads are mostly an implementation distinction, a distinction that shouldn't permeate the language as it tends to do. Isn't his whole 'blocking vs async' duality is ridiculous if you think about it? In both cases, you wait for something to happen. For a high-level language, by what mechanism that waiting happens can be a runtime concern and exposed through common abstractions (e.g. for futures).<a href="https://bsd.network/tags/programming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#programming</a> <a href="https://bsd.network/tags/asyncio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#asyncio</a>

LennyThe fact that each and every async function in <a href="https://digitalcourage.social/tags/Rust" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Rust</a> declares what happens when its cancelled is so important and so good!I remember how much of a PITA <a href="https://digitalcourage.social/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Python</a>'s <a href="https://digitalcourage.social/tags/asyncio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#asyncio</a> task cancellation was, at least back in the 3.4 times.

The Polish DispatchI need some obscure python help, fellow mastodonians:I have a nested async function inside a regular function.I need to test whether to await on it inside a decorator, but neither of `inspect` or `asyncio` helpers work, and .__code__.co_flags do not indicate it being a coroutine/awaitable/...Right now I've added a flag to my decorator to manually control wrapped function behavior, but it's just a workaround.Any tips?

John-Mark GurneyJust realized that Python's asyncio doesn't map to libev well. It appears (I can't find it in docs, and haven't confirmed in source) that with libev, you can set multiple watches of a specific type on a single FD.With asyncio, when you remove a reader/writer, you only specify the fd, implying that you remove all callbacks. I just realized it is undocumented what happens if you call add_{reader,writer} on the same fd, but w/ a different callback. Does it chain?

John-Mark GurneyActually, I take that back. I can't retire it. The reason is that my async tester does a little more than the default does. Mine adds a timeout and prints out a stack trace of where the function was when it was canceled by the timeout.It's easy to end up w/ a deadlock or similar w/ asyncio and this helps catch those failures.<a href="https://flyovercountry.social/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Python</a> <a href="https://flyovercountry.social/tags/asyncio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#asyncio</a>
