Core Panic with WebSocketServer and CORE_DEBUG_LEVEL=5

[theelims]

Hi, first congratulations to this library. I hope this really becomes a popular alternative to the unstable ESPAsyncWebServer world. This is what everyone has been waiting for.

This relates to issue #20.

When httpd_ws_get_fd_info(request->server(), httpd_req_to_sockfd(request->request()) is called the ESP32-S3 crashes.

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.

Core  1 register dump:

Commenting out the line ESP_LOGI(PH_TAG, "ws_handler: httpd_handle_t=%p, sockfd=%d, client_info:%d", request->server(), httpd_req_to_sockfd(request->request()), httpd_ws_get_fd_info(request->server(), httpd_req_to_sockfd(request->request()))); or changing to -D CORE_DEBUG_LEVEL=2 solves the issue.

[pletch]

Suspect the default stack size for the psychichttp httpd server task is too small at only 4K with this ESP_LOGI instruction.

Increasing the psychic http stack size by calling httpd_config option config.stack_size = 6144 prior to server.listen seems to address this problem.

See https://www.esp32.com/viewtopic.php?t=9834 and https://www.esp32.com/viewtopic.php?t=10443.

#74 is essentially the same issue.

this is now fixed in https://github.com/hoeken/PsychicHttp/issues/74 and can be closed
