Title: RE: Destruction of ArrayBean -- Memory Leak?
Hi,
As a follow-up to yesterday's mail, I've created a new issue on JIRA in relation to the client-side memory leak.

Subject: Re: Destruction of ArrayBean -- Memory Leak?
Hi,
I have encountered memory leaks (reported by Purify (on Solaris) and Valgrind (on Linux)) in an AXIS C++ Client application. The leaks are associated with a clone of an array object (created by the SoapSerializer::addOutputCmplxArrayParam method). The cloned object is used to call makeArrayBean after which the clone is de-coupled -- i.e its internal m_Size and m_Array fields are reset before it is destroyed. I understand that the idea of this is that the clone object itself is cleaned up and the ArrayBean object takes ownership of the internal array.
After the Web-service operation has been invoked, the ArrayBean destructor will eventually be called. In the destructor a number of checks are made (see below) before the appropriate delete-function (in generated stub) is made. As earlier raised by Yuan Liu, why is this delete function not invoked for client side AXIS C++ apps? (If I remove the check for AxisEngine::m_bServer in the ArrayBean destructor the tools I use no longer report leaks for my application).
Should this change be made to the AXIS C++ source or are there potential issues with allowing this delete on client-side?
Regards,
Niall.
// Extract from ~ArrayBean
if (USER_TYPE == m_type)
{
if (m_value.cta)
{
if (m_value.cta-pObject)
{
if (AxisEngine::m_bServer)
{
m_value.cta-pDelFunct(m_value.cta-pObject, true, m_nSize);
}
// make sure that the ComplexObjectHandler's destructor does
// not try to delete the objects again
m_value.cta-pObject = NULL;
}
delete m_value.cta;
m_value.cta = NULL;
}
}

Hi,
I just want to know is there a reason why ArrayBeans are only deleted on the
Server as the destructor contains codes like if (AxisEngine::m_bServer).
At the moment, the client is leaking memory whenever it calls
addOutputBasicArrayParam (SoapSerializer.cpp) which create an ArrayBean
with reference to an allocated block of Axis_Array. The ArrayBean is deleted
correctly on server side but client side it is not deleted.
Thanks for all the good work.

Yuan Liu
