Kernel Panic serving anything if local MicroDNSSrv used #25
Description
Make sure you are running the latest version of TinyWeb before reporting an issue.
Device and/or platform:
- MicroPython, TinyPICO (ESP32) (latest - built from source today)
- Built against IDF 4.0 release
- Using latest MicroDNSSrv for DNS + latest TinyWeb for Webserver.
Description of problem:
Webserver is running as expected if I connect to my wifi and run the server with the host set to my IP given by the DNS.
But my use case is to set local DNS and start an AP and connect to my AP, and have it serve pages from that - Making a MicroPython WifiManager-esq system for my application.
If I set the DNS to be MicroDNSSrv using this...
dns = MicroDNSSrv.Create({ '*' : '192.168.4.1' })
And connect to it, as soon as it tries to serve the / page, I get a kernel panic!
Expected:
It should just serve me the page. Even the most basic of pages kernel panics. There should never be a kernel panic from a module.
This setup works with MicroWebServ2 as the web server, and my basic sockets based web server. I moved to TinyWeb as I need an uasyncio based web server as I'm transitioning the rest of my app to be asyncio based.
