[jira] Created: (XERCESC-1873) Memory leaks in Parse function of
XercesDOMParser
Memory leaks in Parse function of XercesDOMParser
-------------------------------------------------
Key: XERCESC-1873
URL: https://issues.apache.org/jira/browse/XERCESC-1873
Project: Xerces-C++
Issue Type: Bug
Components: DOM
Affects Versions: 2.8.0
Environment: Solaris 10.0
Reporter: Vaibhav Agarwal
Hi,
It seems that there is a memory leak in the parse function of XercesDOMParser. Memory used by the server process keeps on increasing after certain number of requests. Is anyone aware of such memory leak existing in Xerces libraries? Below are the details:
OS used: Solaris 10
Xerces version: 2.8.0
Code Snippet which leaks:
RWCString xmlString;
int errorCount = 0;
m_domParser = new XercesDOMParser();
RWCString schemaLocationsString;
bool noNameSpace;
m_xmlDocData.GetSchemaLocation(schemaLocationsString, noNameSpace)
m_domParser->setExternalSchemaLocation(schemaLocationsString);
m_domParser->setValidationSchemaFullChecking(false);
XercesDOMParser::ValSchemes valScheme;
if (m_xmlDocData.GetXsdValidationLevel() == XmlProcessData::VALIDATION_OFF)
valScheme = XercesDOMParser::Val_Never;
else if (m_xmlDocData.GetXsdValidationLevel() == XmlProcessData::VALIDATION_ON)
valScheme = XercesDOMParser::Val_Always;
else
valScheme = XercesDOMParser::Val_Auto;
m_domParser->setValidationScheme(valScheme);
m_domParser->setDoNamespaces(true); // optional
m_domParser->setDoSchema(true);
m_domParser->setErrorHandler(m_errorHandler);
}
RWCString theString = xmlbuffer;
m_errorHandler->resetErrors();
MemBufInputSource* membuf;
membuf = new MemBufInputSource(
(const XMLByte*)theString.data(), strlen(theString.data()), "APIXMLInterface",false);
const unsigned long startMillis = XMLPlatformUtils::getCurrentMillis();
m_domParser->parse(*membuf); //memory utilzation increases here and later on when delete m_domParser is called, it is not released.
const unsigned long endMillis = XMLPlatformUtils::getCurrentMillis();
unsigned long duration = endMillis - startMillis;
m_doc = m_domParser->getDocument();
delete membuf;
membuf = 0;
delete m_domParser;
m_domParser = 0;
Can someone please help me out in this? Have we done something wrong here?
