| Summary | 0005463: TCP connection callbacks - problem | ||||
| Description | I am using libmicrohttpd with MHD_OPTION_NOTIFY_CONNECTION parameter to receive notifications for TCP connection opening/closing. Notifications for opening case are coming through as expected, however I am experiencing problems with closing case, where I am NOT getting the callback when my client terminates, though I can see client FIN packet in tcpdump on the server side and connection stops appearing in netstat. Eventually the closing notification is being delivered by libmicrohttpd but that is just after a new TCP connection is opened. The sequence of callbacks I am seeing is as followed: 1) callback with MHD_CONNECTION_NOTIFY_STARTED - TCP connection A opened 2) callback with MHD_CONNECTION_NOTIFY_STARTED - new TCP connection B is opened 3) callback with MHD_CONNECTION_NOTIFY_CLOSED - TCP connection A closed Of course I would expect nr 3 to come before nr 2. I am using nc to open/close sockets on client end. | ||||

| My first patch relied on MHD_USE_ITC, with 47281241..777d5e04 MHD now sets this flag internally automatically. So this should really work now (at least it does in my tests). | |
