Client Library Hangs Forever after unsuccessful connection to remote auxiliary
(events) port
--------------------------------------------------------------------------------------------
Key: CORE-3718
URL: http://tracker.firebirdsql.org/browse/CORE-3718
Project: Firebird Core
Issue Type: Bug
Components: API / Client Library
Affects Versions: 2.5.1, 2.1.4, 2.5.0
Environment: Superserver, MS Windows, TCP/IP
Reporter: Mark Jones
Priority: Critical
After an unsuccessful attempt to connect the auxiliary port (isc_que_events)
any subsequent api call that needs to communicate with the server hangs forever
(so the client application hangs forever)
Configure the server (superserver) so that the firewall does not block the main
service port (3050) but blocks the specified Aux port (3060 in this case)
--- firebird.conf ---
#RemoteServiceName = gds_db
#RemoteServicePort = 3050
RemoteAuxPort = 3060
------
Make a connection to the remote server using tcp/ip then call isc_que_events
which will timeout after 10-15 seconds with a isc_network_error (335544721).
Now make a call that requires communication with the server (e.g.
isc_start_transaction ) and the application (library) will hang forever
Right now I can see that it goes wrong when it tries to send the subsequent
packet to the server ( port->send(packet) ) but the debugger didnt go any
further into the code from there so unsure excatly where after that it fails.
