Description IBM Bug Proxy 2012-02-22 13:01:27 UTC

This fixes the bug in tog-pegasus, which enables the embedded instanaces to have correct empty string values .

libvirt-cim requires this feature (which worked in tog-pegasus 2.9) to "unset" numerous settings for storage volumes, VCPU limits, and networking ACLs. For
example, without this fix, clients can set VCPU limits on a VM but could not remove them. That breaks all of our existing clients like Director/VMControl
and zHelix.

Comment 1 IBM Bug Proxy 2012-02-22 13:10:25 UTC

------- Comment From sglass.com 2012-02-22 08:04 EDT-------
With SCMO implementation empty string values in embedded instances are
converted to null values during the embedded CIMInstance to SCMOInstance
conversion. This problem is happening because of the _setString() usage which
sets the string size to 0 if the string is empty. This breaks existing
providers. Proposed patch uses _SetBinary() function which is already used
while setting the string values on the normal SCMOInstance.
