Subject: python: Properly report errors if virStreamRecv fails
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=d5f969e13076753e643a49eaeb06d77d75f617f8;p=libvirt.git

python: Properly report errors if virStreamRecv fails

We only want to raise the special value -2. -1 should return None
which tells the bindings to throw an exception.
