#1304 soap context is not being initialized for the code generated by gsoap engine when -p option is used.

[Avinash Magar]

soap context is not being initialized for the code generated by gsoap engine when -p option is used.

Gsoap version : 2.8.108

Example:-

=========== wsdl=======
<complextype name="personalInfo">
<sequence>
<element name="name" type="xsd:string">
<element name="age" type="xsd:int">
</element></element></sequence>
</complextype>
========================

Generate soapStub using below command :-
wsdl2h -d -p -o soap.h above-sample.wsdl
soapcpp2 -j -x -C soap.h

====== soapStub.h =====
/ complex XML schema type 'ns2:personalInfo': /
class SOAP_CMAC ns2__personalInfo : public soap_dom_element {
public:
/// Required element 'name' of XML schema type 'xsd:string'
std::string name;
/// Required element 'age' of XML schema type 'xsd:int'
int age;
public:
/// Return unique type id SOAP_TYPE_ns2__personalInfo
virtual long soap_type(void) const { return SOAP_TYPE_ns2__personalInfo; }
/// (Re)set members to default values
virtual void soap_default(struct soap);
/// Serialize object to prepare for SOAP 1.1/1.2 encoded output (or with SOAP_XML_GRAPH) by analyzing its (cyclic) structures
virtual void soap_serialize(struct soap) const;
/// Output object in XML, compliant with SOAP 1.1 encoding style, return error code or SOAP_OK
virtual int soap_put(struct soap, const char tag, const char type) const;
/// Output object in XML, with tag and optional id attribute and xsi:type, return error code or SOAP_OK
virtual int soap_out(struct soap, const char tag, int id, const char type) const;
/// Get object from XML, compliant with SOAP 1.1 encoding style, return pointer to object or NULL on error
virtual void soap_get(struct soap, const char tag, const char type);
/// Get object from XML, with matching tag and type (NULL matches any tag and type), return pointer to object or NULL on error
virtual void soap_in(struct soap, const char tag, const char type);
/// Return a new object of type ns2__personalInfo, default initialized and not managed by a soap context
virtual ns2__personalInfo soap_alloc(void) const { return SOAP_NEW_UNMANAGED(ns2__personalInfo); }
public:
/// Constructor with default initializations
ns2__personalInfo() : name(), age() { }
virtual ~ns2__personalInfo() { }
/// Friend allocator used by soap_new_ns2__personalInfo(struct soap, int)
friend SOAP_FMAC1 ns2__personalInfo * SOAP_FMAC2 soap_instantiate_ns2__personalInfo(struct soap, int, const char, const char, size_t);
};

================

Implementation of soap_instantiate_ns2__personalInfo in soapC.cpp :-

SOAP_FMAC1 ns2__personalInfo * SOAP_FMAC2 soap_instantiate_ns2__personalInfo(struct soap soap, int n, const char type, const char arrayType, size_t size)
{
DBGLOG(TEST, SOAP_MESSAGE(fdebug, "soap_instantiate_ns2__personalInfo(%p, %d, %s, %s)\n", (void)soap, n, type?type:"", arrayType?arrayType:""));
(void)type; (void)arrayType; / appease -Wall -Werror /
ns2__personalInfo p;
size_t k = sizeof(ns2__personalInfo);
struct soap_clist cp = soap_link(soap, SOAP_TYPE_ns2__personalInfo, n, soap_fdelete);
if (!cp && soap && n != SOAP_NO_LINK_TO_DELETE)
return NULL;
if (n < 0)
{ p = SOAP_NEW(soap, ns2__personalInfo);
// should have below line.
// p->soap = soap
}
else
{ p = SOAP_NEW_ARRAY(soap, ns2__personalInfo, n);
// iterate over the array and assign soap to each object
// p[i]->soap = soap;
k = n;
}
DBGLOG(TEST, SOAP_MESSAGE(fdebug, "Instantiated ns2__personalInfo location=%p n=%d\n", (void)p, n));
if (size)
size = k;
if (!p)
soap->error = SOAP_EOM;
else if (cp)
cp->ptr = (void*)p;
return p;
}

==============================

shouldn't the passed soap context be assigned tp soap context of object created by SOAP_NEW?

Indeed. This was on the TODO list for too long. The 2.8.127 release will include the suggested code. This was tricky, because the soap_dom_element type is not visible to the analyzer so we need to make an exception and also deeper inheritance levels should be covered recursively.

[Robert van Engelen]

Upcoming gsoap 2.8.127 has the code updated.
