memory maangement in generated adb client stub
Hello.
I am using axis2c-bin-1.1.0-linux and axis2-1.3
I am few past weeks learning how to use the generated adb stub using
WSDL2C tool. I was doing as an exercise a simple wsdl service in java
and i need to write test client in C. Using the generated stub took mi
some time, however it compiles and work now.
However, if I repeat calling generated
axis2_stub_op_Service_EventPerformed(stub, env, _eventperformed1);
function with every call it increase allocated memory (if i omit it the
memry footprint is constant). It does not depend on whether the service
is running or not, the continuous memory allocation is the same. I am
not really too familiar with the adb code, so i paste here the function
where i call it and the generated stub. Maybe someone tells me where is
the problem, thanks in advance.
Martin
-------------------------------------------------------------------------------
FIRST function where i use it:
-------------------------------------------------------------------------------
RETURN_TYPE send_single_event(struct event_data *event){
printf ("AXIS2 sendout - single event... \n");
//following i keep still the same, declared on the top
if(EventDTO==NULL) EventDTO = adb_EventDTO_create(env);
status = adb_EventDTO_set_eventTime( EventDTO, env, event->time );
status = adb_EventDTO_set_cID( EventDTO, env, event->cID );
if(status != AXIS2_SUCCESS) return RETURN_FAILURE;
//following i keep still the same, declared on the top
if(_eventperformed1==NULL) _eventperformed1 =
adb_EventPerformed_create(env);
status = adb_EventPerformed_set_param0( _eventperformed1, env,
EventDTO);
if(status != AXIS2_SUCCESS) return RETURN_FAILURE;
_eventperformedresponse2 =
axis2_stub_op_Service_EventPerformed(stub, env, _eventperformed1);
if (_eventperformedresponse2 == NULL){
printf("\t!!! the service is not reachable at expected URI
(wrong URI, service not is running or network connection failed)...\n");
} else {
printf(" - the Service_EventPerformed returns something...\n");
//free memory at the end of processing
adb_EventPerformedResponse_free(_eventperformedresponse2, env);
_eventperformedresponse2 = NULL;
// it frees also the serversResponseDTO, but does not NULL the
pointer
}
return RETURN_SUCCESS;;
}
-------------------------------------------------------------------------------
SECOND - the generated function i call
- i did not find yet how long are some pointers hold somewhere
outside, however all the pointers in beginning are not freed locally

Re: memory maangement in generated adb client stub
Posted by martin spurek <ma...@vsb.cz>.
Hello. I uset the valgrind tool to get some debug output, however i
cannot say i understand all the output. I use there one thread to run
the axis2 related stuff. Just what i noticed where the thread is exiting
there may be something wrong (i used threads for first time using just
some examples). However the other informations could be helpful for you...

Re: memory maangement in generated adb client stub
Posted by martin spurek <ma...@vsb.cz>.
Hi.
I can try do the testing. I am not developing in c so often so i am not
so experienced, I did not have need use such tool you mentioned yet. If
i will find something i will post it here.

No, you don't have to. it will be freed when the request/response adb is freed,
) + always

Yea, I have not tested the memory management stuff on codegen
recently. It will be helpful if you can support on this with a tool
like valgrind or purify locating where the leaks are.

Re: memory maangement in generated adb client stub
Posted by martin spurek <ma...@vsb.cz>.
H Dimuthu. Yes, you are right, i am acutally using the nightly build for
the java and WSDL2C part. I updated it week or two ago from the version
i mentioned here and i did not remember it at the moment.
What i am actually trying to do:
I would like to create once one adb_EventDTO_t, one
adb_EventPerformed_t and reuse it and the memory free at the end of
program (i do not have to free the adb_EventDTO_t structure?) + always
(at every call) get response (it is created) and free of my own.
What i actually find strange on it: the memory footprint of the program
grows with every call the service very significantly (3 calls, initial
size 2808KB final size 2836KB). If i would use it in some project to run
on machine in scale of days it could be quite hardly usable, that is why
i am asking about the memory management in the generated stubs (either i
use adb* wrong or the memory management we could fix...).

Re: memory maangement in generated adb client stub
Posted by Dimuthu Gamage <di...@gmail.com>.
Hi martin,
If you are using adb in client side you have to explicitly free the
allocated adb object for (only) the request and response. That is call
adb_EventPerformedResponse_free and adb_EventPerformed_free at the
end.
Seems you are using the nightly build
(http://people.apache.org/dist/axis2/nightly), although you said you
are using axis2-1.3? . If so surely you will be working with the
latest fixes.
Thanks
Dimuthu
