Build Update for ovsrobot/ovs

Build: #3638
Status: Passed

Duration: 11 mins and 8 secs

Message: python: Send notifications after the transaction ends

The Python IDL notification mechanism was sending a notification
for each processed update in a transaction as it was processed.
This causes issues with multi-row changes that contain references
to each other.

For example, if a Logical_Router_Port is created along with a
Gateway_Chassis, and the LRP.gateway_chassis set to that GC, then
when the notify() passes the CREATE event for the LRP, the GC will
not yet have been processed, so __getattr__ when _uuid_to_row fails
to find the GC, will return the default value for LRP.gateway_chassis
which is [].

This patch has the process_update methods return the notifications
that would be produced when a row changes, so they can be queued
and sent after all rows have been processed.

Fixes: d7d417fcddf9 ("Allow subclasses of Idl to define a notification hook")
