Summary:
dpws_process_request end in infinite loop

Detailed description
When using generic skeletons, dpws_process_request calls the given callback function in which a parsing of incoming message is supposed to tak place. However if the EPX parser reaches the end of the body of the message by reaching the EPX_EVT_END_FRAGMENT event, than back in the dpws_process_request function at the line 122 there is a for cyclus, that consumes events that were not read and this cycle waits for the EPX_EVT_END_FRAGMENT which has been already read and thus the program ends in an infinite loop. The condition for exiting the loop shoud contain EPX_EVT_END_FRAGMENT && EPX_EVT_IDLE && EPX_EVT_ERROR I think.

Hi Jiri,

I agree that adding your test would be safer. However, I'm interested by some more details because from what I see, dpws_process_request() does not consume the first event since it uses epx_get_event() before testing and only calls epx_next() if test fails.
Are you sure that your custom payload processor does not consume events after EPX_EVT_END_FRAGMENT ?

BR,

Stéphane
