Re: [lwip-users] httpd POST gets stuck after few requests

Added "if (p != NULL) pbuf_free(p);" to the httpd_post_receive_data() and works like a charm. Thank you all. út 4. 2. 2020 v 17:49 odesílatel goldsimon napsal: > > > Trampas Stern wrote: > >err_t httpd_post_receive_data(void *connection, struct pbuf *p) > >{ > > pbuf_free(p); > >return ERR_OK;

Re: [lwip-users] httpd POST gets stuck after few requests

I found some info in httpd.c that has call to httpd_post_receive_data() /** Pass received POST body data to the application and correctly handle * returning a response document or closing the connection. * ATTENTION: The application is responsible for the pbuf now, so don't free it! * * @param

Re: [lwip-users] httpd POST gets stuck after few requests

I followed the contrib-2.1.0/examples/httpd/post_example/post_example.c, I did not notice any free of pbuf there. I guess if application is responsible for pbuf free then only httpd_post_receive_data() is candidate as it has pointer to data pbuf as parameter? út 4. 2. 2020 v 17:36 odesílatel gol

Re: [lwip-users] httpd POST gets stuck after few requests

I did search of POST related problems sorted by date. I will do so again. PBUF_POOL_SIZE is affecting number of POST I can do directly. That is, I can do as many posts as PBUF_POOL_SIZE is defined. @Trampas Stern I

Re: [lwip-users] httpd POST gets stuck after few requests

OK, so my lwip gets stuck exactly after 16 POSTs. Maybe the POST is not freeing PCB, or other structures properly. And I have overridden these out of default: #define MEMP_NUM_SYS_TIMEOUT (LWIP_NUM_SYS_TIMEOUT_INTERNAL + 3) #define MEMP_NUM_UDP_PCB 6 #define MEMP_NUM_TCP_PCB 6 #define MEMP_NUM_TC

Not sure which parameter is defining maximum number of connections. Processor is ARM 32bit STM32F407. út 4. 2. 2020 v 15:38 odesílatel Trampas Stern napsal: > What is the maximum number of connections you have setup? > > Which processor are you using? > > Trampas > > On Tue, Feb 4, 2020 at 9:08

What is the maximum number of connections you have setup? Which processor are you using? Trampas On Tue, Feb 4, 2020 at 9:08 AM Adam Baron wrote: > I'm bit new to lwip, and I'm using it on STM32407 with ChibiOS which is > RTOS. I'm using current stable version of lwip and bindings form ChibiOS

[lwip-users] httpd POST gets stuck after few requests

I'm bit new to lwip, and I'm using it on STM32407 with ChibiOS which is RTOS. I'm using current stable version of lwip and bindings form ChibiOS to run it as threads. My static and also dynamically generated html pages are served well and without any issues. But I have problem with POST. I use the
