[mkgmap-dev] Split planet error

Fri Jan 15 13:37:38 GMT 2010

Based on the error message you've shown, I'm pretty sure there isn't a problem 
with the XML parser itself (it handles <changeset/> vs </changeset> automatically). 
The end of the input stream is being reached, so it looks like either the 
planet file that you're trying to parse is corrupt, or the bz2 code is having 
trouble uncompressing the file and thinks it has reached the end earlier 
than it should. I've seen the latter happen before, unfortunately the bz2 
unpacker we're using isn't all that great... If you're sure the planet file 
is OK and suspect the bz2 code is at fault, you could uncompress the planet 
file (assuming you have a spare 140GB or so!) and try again.

I realise this is hardly ideal. Rather than try to fix the bz2 code, I'll 
probably add a parameter that allows the input to come from stdin. That way 
it will be possible to pipe the osm file from an external uncompression tool, 
which should also greatly help performance.
