Recursion error from .pyhtml when threaded=True

[elixx]

If I start the process with mws.Start(threaded=True), attempting to load any .pyhtml page renders:

PyHTML page execution error
maximum recursion depth exceeded (line 18)

This does not happen at all if I start with threaded=False. Is this to be expected?

I reviewed https://github.com/jczic/MicroWebSrv/issues/36 and tried a few different firmware versions, but still the same result. I think these boards are comparable to a LOLIN32.

Trying with SPI firmware, I get a reboot and the following:

>>> ***ERROR*** A stack overflow in task mp_thread has been detected.
abort() was called at PC 0x40091d8c on core 1

I found that calling the same function from a route works totally fine in threaded mode and not. It appears to be something confined to the handling of pyHTML files (from what I can see so far).

Hello @elixx and thanks to interesting:) I know this problem with micropython because there are a large number of function penetrations and this can cause a stack overflow. And with the pyhtml model, it's even more... A solution is to access the micropython variables to increase the stack maximum value and recompile the firmware :o Do you can try that for your needs ?

Thanks -- I'll give that a shot.

pyHTML would be nice to get working, eventually on my board -- but I have a few different ones on the way, and see how it goes on those, too. Then I'll pursue rolling my own firmware. =)

Right now I switched to using the request handler decorators to get the functionality that I want -- so far, so good!

Thank you!

Hello,

I released a fully new version (v2.0) of my web server here : github.com/jczic/MicroWebSrv2. Open source MIT, fully asynchronous, more robust, more fast and more efficient! It is delivered with a good documentation.

Thank you for your support and feedback. ☺️
