Another old patch pending, yes this need to be fixed, I just changed
a couple of things:
- made xmlPushinput return an int, that's a compatible change
- made pushInput return -1 on error instead of -1 like all other push
functions, none of libxml2 code was testing the return value anyway
because this was broken, 0 is a legal value which you should get
when pushing the first entity.
Some further cleanup would be to check inputPush() return value
everywhere, and that's around 30 places within libxml2. Most of them
though are used for the main entity, so I guess if it fails the failure
is caught pretty soon as there is nothing to parse !
thanks for the patch, sorry for the delay,
Daniel
