`FletSocketServer` Error #2781

ndonkoHenri · 2024-03-02T12:22:18Z

@ndonkoHenri , flet pre release has some issues. Not able to run any script. Not even the example code from tutorials.

raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 404: Not Found

...

AttributeError: 'FletSocketServer' object has no attribute '_FletSocketServer__receive_loop_task'. Did you mean: '_FletSocketServer__receive_loop'?

System: Windows 11, Python=3.11, Conda environment.

@kXborg thanks for reporting, we will have a look.

ndonkoHenri · 2024-03-03T01:47:16Z

@kXborg I am not getting that error with the latest pre (0.21.0dev2459 on macOS+py3.11).
I suggest you retry with the latest once more.

I have the same error here, running the boilerplate from the docs, and I also get the exact same error as @Marmaduke1st

I am running Python 3.11.7 on Arch, installed flet with pip install, in virtual env, here are the version that got installed:

flet==0.21.1
flet-core==0.21.1
flet-runtime==0.21.1

and error is :

AttributeError: 'FletSocketServer' object has no attribute '_FletSocketServer__receive_loop_task'. Did you mean: '_FletSocketServer__receive_loop'?

ndonkoHenri · 2024-03-07T11:52:40Z

This issue might be Linux-specific.

Marmaduke1st · 2024-03-07T12:30:32Z

argeed, works in windows

yashasolutions · 2024-03-07T12:56:10Z

This issue might be Linux-specific.

ok so I figure the source of the issue, it's actually the result of library dependencies (in my case it was linked to libmpv, and as far as I can see in @Marmaduke1st case it's linked to a gtk missing dependancy)

I created a separate issue #2823 (because in my case I did have the libraries, just some versioning issue which I fixed some hacky solution.)

Fix #2781

argeed, works in windows

nah, windows 10 also has this problem

ndonkoHenri · 2024-03-18T12:54:47Z

This issue has already been fixed.
Install the latest pre-release and retry.

* Fix "_FletSocketServer__receive_loop_task" error on Linux Fix flet-dev#2781 * Replace deprecated `datetime.utcnow()` with `datetime.now(UTC)` Fix flet-dev#2827 * Fix a call to `self.__executor.shutdown` for Python 3.8 Fix flet-dev#2825 * Use `timezone.utc` instead of `datetime.UTC` * Add client IP and user agent to a session ID To make session ID hijacking harder * Generate crypto-strong strings * Flet version bumped to 0.21.2 * Ensure control exists in _process_remove_command * Store session ID in SessionStorage instead of window.name We've been storing sessionID in window.name because of flet-dev#1629. However, `window.name` is not preserved in mobile Safari during OAuth session. It looks like Flutter has fixed that in launchUrl() (https://github.com/flutter/packages/blob/main/packages/url_launcher/url_launcher_web/lib/url_launcher_web.dart#L87) https://stackoverflow.com/a/73821739/1435891 * Changelog updated
