Not compatible with Micropython 1.21.0?

[kenjican]

  MicroWebSrv2  2.0.6 have been working well with MicroPython V.1.20.0 and versions before.

  But , at version Micropython 1.21.0 , when connecting it shows  server closed as below:

MWS2-INFO> Server listening on 0.0.0.0:80.
MWS2-INFO> Starts the managed pool to wait for I/O events.
MWS2-INFO> Server 0.0.0.0:80 closed.
MWS2-INFO> Stops the managed pool.

Anyone bump into this problem also?

Is this still the case after the recent commits?

[kenjican]

I tried recent commits and Micropython 1.22.1 。 Sever not closed but still can not open the html page. as below:
---------------------------
- Python pkg MicroWebSrv2 -
- version 2.0.6 -
- by JC`zic & HC2 -
---------------------------

• [@webroute] GET /scan
• [@webroute] POST /saveJson
• [@webroute] GET /reset
• [@webroute] POST /cmds
  MWS2-INFO> Server listening on 0.0.0.0:80.

Same here. Breaking commit is 2f1e982. The server starts and hangs on MWS2-INFO> Starts the managed pool to wait for I/O events.
When I try to open a webpage the curl/browser hangs and also the webserver hangs. If I try to stop it with CTRL+C it doesn't responds for about 30 seconds before the key presses get registered and the server stops

Micropython versions tested: 1.22.2 and all in between the latest master
ESP-IDF versions tested: latest 5.1 and 5.2

Hello and thank you for your feedback.
can you try to start the server with :
StartManaged(0)
or
StartManaged(2)
?

[ekondayan]

With StartManaged(2) the server hangs and even CTRL+C does not work
With StartManaged(0) I am able to halt the server with CTRL+C. Once I was able to download the index.html, but even then the server responded about 20 seconds later and then hanged again.

Here is the output when I stop it with CTRL+C

MWS2-INFO> Server listening on 0.0.0.0:80.
MWS2-INFO> Starts the managed pool to wait for I/O events.

hit 5-10 times CTRL+C

MWS2-INFO> Server 0.0.0.0:80 closed.
MWS2-INFO> Stops the managed pool.
Traceback (most recent call last):

I'd like to help you debug it, but I do not know where to start.

Same problem here. Server starts but cannot get to any routes. (1.22.0 here too)

update:
I rolled back to 1.20 Micropython and 2.0.6 of MicroWebSrv2 and I am now able to get responses from the webserver.

Not that I am running this on an ESP32-Wroom in embedded mode. So I can confirm what @ekondayan was saying about the commit breaking things.

[ekondayan]

I've been testing the latest commit (4a7f599) - it is still not working reliably but this time with a twist.

This time I am able to get the index.html a few times in a row(using curl) but then the server stops serving again. I wasn't able to get a complete webpage using a regular browser - index.html, CSS and two JS files( 420KB in total ). The difference now is that I can get at least one index.html served but the server blocks for the rest of the page assets. I also noted that in this blocked state, the server is handling the websocket messages correctly.

If you give me a modified XAsyncSockets.py, stuffed with debug print statements, I can send you the output.

[jczic]

Hmm, thank you @ekondayan.
Strange indeed.
And how do you start the server at the beginning?
I use it on big projects with TLS/SSL (on Azure cloud) and it still works. I launch it with 5 parallel processes.
Do you use it in embedded mode or on a normal server (linux or other)?

[ekondayan]

    mws2 = MicroWebSrv2()
    mws2.RootPath = '/www'
    mws2.SetEmbeddedConfig()  # For embedded MicroPython, use a very light configuration,
    mws2.DisableSSL()
    mws2.NotFoundURL = '/'  # All pages not found will be redirected to the home '/',
    mws2.StartManaged()

My environment is:

• ESP32-PICO-D4 - 2MB RAM and 8MB flash.
• Micropython - master branch(I've also tested some commits between the latest master and v1.22.2) compiled with ESP-IDF v5.2. I've also tested to compile with ESP-IDF v5.1.

[ekondayan]

I've tested the latest commit and it still does not work on esp32 with micropython
