> 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?
