httpd_stop() hangs

[steeveone]

Hello, i need to stop an http server instance, so I have following code:

Code: Select all

static void app_prov_stop_service(void)
{

	httpd_unregister_uri(g_prov->server, "/status");
	httpd_unregister_uri(g_prov->server, "/provisioning");
	ESP_LOGI(TAG, "stopping httpd");
	if (g_prov->server)
	{	httpd_stop(g_prov->server);
		g_prov->server = NULL;
	}
	ESP_LOGI(TAG, "httpd stopped");
	[...]

this function is called inside a task triggered by a timer.
When called httpd_stop() the task hangs (do nothing) and I don't know why or how to debug...
esp continue listening on port 80 and urls get correctly unregistered.
In logs I see

I (66029) app_prov: stopping httpd

and not "http stopped".
Thanks

I had the same strange problem and after hours of debugging I found that it was some defines missing (http_server/simple example has these):

CONFIG_LWIP_NETIF_LOOPBACK=y
CONFIG_LWIP_LOOPBACK_MAX_PBUFS=1

Add this to sdkconfig and it works somehow...
