[Planetlab-devel] editRecord.py (geniwrapper)

[Ihsan Qazi]

Hi Faiyaz,

Thanks! The getRecord.py and SetRecord.py methods were quite helpful.

I have another observation. While I'm able to update 'user' records via 
sfi, I get a "Missing authority" exception when updating a 'slice' 
record, even though I can delete a named slice or remove it from the 
registry. It appears that the name of the slice, which is pl_test1 in my 
case, is read from the XML file and set to the hrn, which I think is not 
the right assignment to do (unless it gets translated to the hrn 
somehow). It should, perhaps, be set to plc.pl.test1 (which is the hrn 
of the slice in my case). I checked this in the code, it turns out that 
when I delete a named slice, the argument of the function 
'get_slice_hrn(slice_hrn)' is set to the hrn of the slice (which is 
given from the command-line) but when updating a slice record, it is set 
to the name rather than the hrn of the slice. Note that this is not the 
case with a user record, in which case the name==hrn in the XML file and 
so this issue doesn't arise. When I set the name equal to hrn in the XML 
file manually, I get a "500 Internal Server Error", which suggests that 
the setting of the name perhaps had something to do with the issue but 
not sure why the Internal Server Error appears. Have you tried updating 
a slice record via sfi?

I have copied the output below.

Thanks!
Ihsan
