Crash on ESP8266-RTOS-SDK #38

Closed nikp123 closed 7 months ago

nikp123 commented 1 year ago

Steps to reproduce:

  1. Use this docker image. The command is similar to sudo docker run -it --rm -v (pwd):/project -w /project --device /dev/ttyUSB0 mbenabda/esp8266-rtos-sdk bash.
  2. Modify the example/demos to host an HTTP server (using the built-in httpd library)
  3. Wait for a client to load a page
  4. Close the HTTPD handle
  5. Try to close the wireguard context (crashes)

trombik commented 7 months ago

The library does not support ESP8266 RTOS SDK. As far as I know, it has been unmaintained for a long time.

Mind changing this then? Because it's misleading.

PS: But AFAIK, outside of this bug, the library works perfectly. So you may just leave it as "not officially supported" or "confirmed working by volunteers, but not supported anymore"?
