Comment 2 Gunannan Ren 2013-04-18 12:29:14 UTC

commit 4b143ab23173000d1afa258726be0ff38cf2b386
Author: Guannan Ren <gren>
Date:   Thu Mar 21 11:24:49 2013 +0800

    python: fix bindings that don't raise an exception
    
    For example:
     >>> dom.memoryStats()
     libvir: QEMU Driver error : Requested operation is not valid:\
             domain is not running
    
    There are six such python API functions like so.
    The root reason is that generator.py script checks the type of return
    value of a python stub function defined in libvirt-api.xml or
    libvirt-override-api.xml to see whether to add the raise clause or not
    in python wrapper code in libvirt.py.
    
    The type of return value is supposed to be C types.
    For those stub functions which return python non-integer data type like
    string, list, tuple, dictionary, the existing type in functions varies
    from each other which leads problem like this.
    
    Currently, in generator.py, it maintains a buggy whitelist for stub functions
    returning a list type. I think it is easy to forget adding new function name
    in the whitelist.
    
    This patch makes the value of type consistent with C type "char *"
    in libvirt-override-api.xml. For python, any of types could be printed
    as string, so I choose "char *" in this case. And the comment in xml
    could explain it when adding new function definition.
    
          <function name='virNodeGetCPUStats' file='python'>
            ...
     -      <return type='virNodeCPUStats' info='...'/>
     +      <return type='char *' info='...'/>
            ...
          </function>

Wayne, please test this backport patch. Don't make any regression is the point.
Thanks.

As far all affected API works fine.

It seems work well, so I change the status to VIRIFIED.

Comment 12 Jincheng Miao 2013-08-22 14:43:28 UTC

Sorry, I miss the part:
>>> dom1.memoryStats()
libvir: QEMU Driver error : Requested operation is not valid: domain is not running

It still do not raise an exception.

Comment 13 Jincheng Miao 2013-08-23 04:28:16 UTC

Sorry for my careless, the problem I met is because I import the original libvirt.py which is backed up in local directory. 

Thanks for Wayne and Guannan Ren's help.

The following is verification steps:

As we seen, for the shutoff domain, each libvirt python API will raise an exception. So I change the status to VERIFIED
