Key: SAVAN-6
URL: https://issues.apache.org/jira/browse/SAVAN-6
Project: Savan
Issue Type: Bug
Environment: Windows XP, Intel P4
Reporter: Vasiliy Sokov
Priority: Critical
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.
