[jira] Created: (SAVAN-7) Publishing_client crashes when trying to

Publishing_client crashes when trying to publish message when more then 1 subscription to this event source exists at moment.
-----------------------------------------------------------------------------------------------------------------------------
Key: SAVAN-7
URL: https://issues.apache.org/jira/browse/SAVAN-7
Project: Savan
Issue Type: Bug
Environment: Windows XP, Intel P4
Reporter: Vasiliy Sokov
Hello.
I've already fix this problem.
The cause is in module savan_subscriber.c, function savan_subscriber_publish, line 420:
******************************************************************
/* Set service client options */
axis2_svc_client_set_options(svc_client, env, options);
axis2_svc_client_send_robust(svc_client, env, payload);
axiom_node_detach(payload, env); //Vsokov 21.0.2008 insert this to prevent payload corruption in subsequent "publish" calls with some payload.
if(svc_client)
axis2_svc_client_free(svc_client, env);
******************************************************************
The call of axis2_svc_client_send_robust() attaches payload to svc_client. Thus, axis2_svc_client_free() removes payload at the same time with removing of svc_client, and following call of savan_subscriber_publish() by savan_publishing_client_publish() with same payload causes access to free'd memory.
To prevent it, i've insert axiom_node_detach() before call of axis2_svc_client_free(). Now, i can subscribe several listeners to one event source at the time.
Best regards,
Vasiliy Sokov.
