Greetings libxml gurus!
We are using XMLSec library built on top of libxml2 to process some large
XML files, however it doesn't seem to work for files >2GB, which is
unfortunately what we need.
I'd like to ask if the library should support processing that large files
(otherwise, this might be a bug).
It seems there's a limitation in the struct _xmlOutputBuffer, that stores
written bytes in a signed int - therefore the max limit is 2GB.
Here it is:
http://git.gnome.org/browse/libxml2/tree/include/libxml/xmlIO.h#n141
We'd really like if the library could support 64 bit sizes and I see the
struct _xmlParserInputBuffer, that's nearby, does. It uses unsigned long
that's 64bit for x86_64 architecture, we are building for.
It might really help us if someone here could know what else will need to
be fixed for the whole thing to work. If it's going to be a patch or a
full scale project.
Thanks in advance for your help.
Vit Zikmund
