Robert Lazarski resolved AXIS2C-1568.
-------------------------------------
Fix Version/s: 2.0.0
(was: 1.7.0)
Resolution: Fixed
Implement automatic reconnection when keep-alive connections timeout.
When a server closes an idle keep-alive connection, the client now:
1. Detects the timeout (status code -2)
2. Removes the stale connection from the pool
3. Retries with a new connection (max 1 retry)
Changes:
- http_client.c: Return AXIS2_HTTP_CLIENT_STATUS_TIMEOUT (-2) for timeouts
instead of generic -1 error, enabling retry logic
- http_sender.c: Add keepalive_timeout_retries counter and retry logic
that removes stale connections and retries on timeout
- axis2_http_transport.h: Define AXIS2_HTTP_CLIENT_STATUS_TIMEOUT (-2)
and AXIS2_HTTP_CLIENT_STATUS_ERROR (-1) constants
- axis2_http_sender.h: Add axis2_http_sender_set_so_timeout() and
axis2_http_sender_get_so_timeout() functions
The -2 status code is now documented:
- -1 = General error (AXIS2_HTTP_CLIENT_STATUS_ERROR)
- -2 = Connection timeout (AXIS2_HTTP_CLIENT_STATUS_TIMEOUT
> In keep alive mode, client reuses a connection even if the connection has
> already closed.
