Hi All,
I am just getting back to the xerces-c-dev mailing list after a long time. I did browse the archives before posting, so sorry if I may have missed any response on this.
From what I understand, just releasing element nodes does not free up the memory until the document node is destroyed. Are there any plans on changing this behavior?
We have some applications that need to run 24x7 and constantly add and delete element nodes and attributes from the DOM. The behavior that Xerces has right now is the memory keeps increasing and there is no way to free up the space.
Is there any workaround for this (short of releasing the document and recreating it?)
What makes it bad for us is, lots of attributes are created and because of Bug 13197, they never get deleted either when the element is released.
In a recent posting, Gareth mentioned he had a detailed description on memory management to the mailing list a few months back, does anyone have a link to it? I could not find that from the archives.
Here is what I am trying to do….
/*********************************************************************/
DOMImplementation* impl = DOMImplementationRegistry::getDOMImplementation(X("Core"));
DOMDocument* doc = impl->createDocument(
0, // root element namespace URI.
X("company"), // root element name
0); // document type object (DTD).
DOMElement* rootElem = doc->getDocumentElement();
//Add and remove 100000 nodes, memory keeps increasing
for (int i = 0; i < 100000; i++)
{
DOMElement* prodElem = doc->createElement(X("product"));
rootElem->appendChild(prodElem);
//Now remove the child node...
rootElem->removeChild(prodElem);
prodElem->release();
}
/*********************************************************************/
Any help or pointers would be appreciated,
Thanks,
Ravin
