| Doc Text: |
Cause: The libvirt python bindings for querying block job status were not distinguishing between an error and no status available.
Consequence: Code that was polling for the completion of a block job had to deal with a python exception, and could not distinguish it from an actual error.
Fix: The bindings now return an empty dictionary when there is no job and no error in determining that fact.
Result: The binding can be used more reliably in managing block jobs.

In previous version like libvirt-0.10.2-29.el6.1, Libvirt python API will None, and raise a exception: # python Python 2.6.6 (r266:84292, Sep 4 2013, 07:46:00) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>> con=libvirt.open(None) >>> dom=con.lookupByName('r6') >>> dom.blockJobInfo('hda', 0) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1826, in blockJobInfo if ret is None: raise libvirtError ('virDomainGetBlockJobInfo() failed', dom=self) libvirt.libvirtError: virDomainGetBlockJobInfo() failed This NoneType return is fixed in libvirt-0.10.2-29.el6_5.2: # python Python 2.6.6 (r266:84292, Sep 4 2013, 07:46:00) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>> con=libvirt.open(None) >>> dom=con.lookupByName('r6') >>> dom.blockJobInfo('hda', 0) {} So I change the status to VERIFIED.
