Access violation in CopyHelper
------------------------------
Key: TUSCANY-1225
URL: https://issues.apache.org/jira/browse/TUSCANY-1225
Project: Tuscany
Issue Type: Bug
Components: C++ SDO
Affects Versions: Cpp-current
Environment: Win32, PHP
Reporter: Caroline Maynard
Cloning a DataObject withe a property that has been explicitly set to null
results in an AccessViolation:
commonj::sdo::CopyHelper::internalCopy(commonj::sdo::RefCountingPointer<commonj::sdo::DataObject>
{...}, unsigned char 0x01) line 277 + 3 bytes
commonj::sdo::CopyHelper::internalCopy(commonj::sdo::RefCountingPointer<commonj::sdo::DataObject>
{...}, unsigned char 0x01) line 403 + 41 bytes
commonj::sdo::CopyHelper::copy(commonj::sdo::RefCountingPointer<commonj::sdo::DataObject>
{...}) line 267 + 29 bytes
sdo_do_clone_obj(_zval_struct * 0x0120c050, void * * * 0x003d2a20) line 208 +
33 bytes
On the second entry to internalCopy(), the dataObject is null, which results in
the AccessViolation when trying to get the DataFactory.
Example:
schema:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema";
xmlns:ord="orderNS" xmlns:cust="customerNS" targetNamespace="orderNS">
<include schemaLocation="./Customer.xsd"/>
<element name="order" type="ord:OrderType">
<complexType name="OrderType">
<sequence>
<element ref="cust:customer"/>
</sequence>
</complexType>
</element>
</schema>
document:
$customer_xsd = <<<EOF2
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema";
xmlns:cust="customerNS" targetNamespace="customerNS">
<element name="customer" type="cust:CustomerType">
<complexType name="CustomerType">
<sequence>
</sequence>
</complexType>
</element>
</schema>
logic:
$xmldas = SDO_DAS_XML::create('Order.xsd');
$order = $xmldas->createDataObject('orderNS','OrderType');
$order->customer = null;
$o = clone $order;
If customer is unset, there is no problem. Or if it is set to a real data
object there is no problem either.
