[jira] Commented: (XERCESC-1624) Memory leak on Tandem platform
Posted by "Rinil Baxi (JIRA)" <xe...@xml.apache.org>.
[ http://issues.apache.org/jira/browse/XERCESC-1624?page=comments#action_12427128 ]
Rinil Baxi commented on XERCESC-1624:
-------------------------------------
DOM parser API DOMBuilderImpl::parseURI is invoked with the name of
the XML file to be parsed as the argument. This API invokes the
method XMLPlatformUtils::getFullPath. getFullPath method returns the
the fully qualified path of the file. This methods declares a local
char pointer to hold the current directory name. This char pointer
is not released before returning from the method. This leads to a
memory leak.
Relevant part of Code:
char* newSrc = XMLString::transcode(srcPath, fgMemoryManager);
// Use a local buffer that is big enough for the largest legal path
char* tmpPath = dirname((char*)newSrc); < ---- char pointer
declared not deleted
if (!tmpPath)
---------------------------------------------------------------------------------------------
Recommended Fix
-----------------------------
char* newXMLString = (char*) fgMemoryManager->allocate
(
(strlen(tmpPath) +1) * sizeof(char)
);//new char [strlen(tmpPath) +1];
ArrayJanitor<char> newJanitor(newXMLString, fgMemoryManager);
strcpy(newXMLString, tmpPath);
strcat(newXMLString , "/");
fgMemoryManager->deallocate(newSrc); ---------> This will deallocate the char pointer declared
