free memory after invoke web service

[Yong Yang <y....@querix.com>]

Hi, I would like to free these memories that are dynamically allocated using env->allocator in my client program. For example, there are the following structures
    1) axis2_env* env
    2) axis2_options_t* options
    3) axis2_endpoing_ref_t* endpoint_ref
    4) axis2_svc_client_t* svn_client
    5) axis2_namespace_t* name_space[]
    6) axis2_node_t* payload
    7) axis2_node_t* return_node

If I first free svn_client, then payload, name_space, return_node,..,env. there is a segmentation fault when I tried to free name_space.
But If I first free payload, name_space, return_node, svn_client,..., env, there is a segmentation fault when I tried to free svn_client.

May I know which struture I should explcitly deallocate? Do I need to free some of these kind of structures in my server program explicitely ?

many thanks inadvance.

best regards
yong

when u pass payload to svc client (through svc_client_create) ,
svc_client will get the owneship of  that payload. According to my
knowledge freeing svc_client should do the freeing of payload also.

yes..that should be , svc_client going to free payload again.

I think calling AXIS2_SVC_CLIENT_FREE and axis2_env_free would be fine.
BTW way if you feel there is memory leaks remains, we alway welcome a
jira report with valgrind memory leak report.

please follow the way our samples wrote. Because we were able to hit
memory leak 0 with those samples. 


thanks,
Dinesh
