Hi list,
I (actually a very important customer ;-) was bit by the 10MB size limit
introduced in libxml2 2.7.3. Actually, we are using 2.7.7...
The code basically does the following (error handling omitted for clarity,
actual code is more complex):
----- snip -----
xmlDocPtr doc = NULL;
xmlNodePtr node = NULL;
xmlTextWriterPtr writer = NULL;
char huge[ 100*1024*1024 ] = { 'a' };
int written;
doc = xmlNewDoc( (xmlChar *) "1.0" );
node = xmlNewDocNode( doc, NULL, (xmlChar *)"node", NULL );
xmlDocSetRootElement( doc, node );
writer = xmlNewTextWriterTree( doc, node, 0 );
xmlTextWriterStartElement( writer, BAD_CAST "huge" );
written = xmlTextWriterWriteBinHex( writer, huge, 0, sizeof( huge ) );
----- snip -----
With libxml2 V2.7.7 xmlTextWriterWriteBinHex() always returns -1 and error
analysis reveals that the SAX2 parser hit the 10MB limit.
I was bypassing this by eliminating the size limit check in SAX2.c and
recompiling libxml2 but I do not really like this "solution".
So the question is if there is a standard way of passing the
XML_PARSE_HUGE option to the SAX2 parser used under the hood of the
xmlTextWriter-family functions.
I have done extensive research but was not able to find anything useful. I
have checked but did not find a compile-time option to eliminate the 10MB
size limit.
Thanks and best regards,
Michael Kwasigroch
