Alberto Massari resolved XERCESC-2019.
--------------------------------------
Resolution: Fixed
Fix Version/s: (was: 3.1.1)
3.2.0
Assignee: Alberto Massari
Xerces has always been conservative with the memory it had allocated, i.e. it
never deallocated the memory of a DOMText node when an append() was called, to
avoid crashing the client code that had retrieved the previous pointer via a
call to getNodeValue(). In your case this implied allocating a lot of
intermediate memory blocks before the 250Mb needed by your Base64 string were
finally allocated. I have checked in a workaround that allows the parser (and
only the parser) to deallocate them.
> Error in memory allocation for even small messages.

> I have my xsd schema using which i have created my standard xml.
> After creating the xml i fill the values for each tag in my xml.
> I get memory allocation error when i try to traverse through the xml and set
> the values for each tag in my xml.
> I get allocation error when my program calls the setTextcontent() of
> xerces.It is crashing in DOMDocumentImpl.cpp allocate(size).(2nd if condition
> in that function)
> Is there any setting that needs to be done for memory allocation? How much is
> the maximum size of xml that xerces can parse?how do we manage the memory
> allocation and deallocation in DOM?
