[ovs-dev] [PATCH v4 0/2] Partial cluster support in Python IDL client

[nusiddiq at redhat.com]

From: Numan Siddique <nusiddiq at redhat.com>

Python IDL library is lacking the functionality to connect to the
clustered db servers by providing multiple remotes (like -
"tcp:10.0.0.1:6641, tcp:10.0.0.2:6641, tcp:10.0.0.3:6641") in the
connection string.

This patch adds this functionality to the python idl library.
It still lacks the feature to connect to the master of the cluster.
To add this
  - python idl client should monitor and read the '_Server' schema
  - connect to the master of the cluster.

I will submit the patch once that is ready. But for now I think this
is good enough for the clients to connect to the cluster dbs.


v3 -> v4
--------
p1 -> As per Ben's suggestion, used the select.poll() to 
know the connection status. In case eventlet/gevent is used and 
select.poll is monkey patched, then get the original select.poll()
using eventlet.patcher.original/gevent.monkey.get_original
functions.

v2 -> v3
--------
Addressed the review comments from Ben to parse the remote in
db/idl.py

v1 -> v2
--------
Deleted the debug code which I forgot to cleanup when sending v1.

Numan Siddique (2):
  ovs python: ovs.stream.open_block() returns success even if the remote
    is unreachable
  python jsonrpc: Allow jsonrpc_session to have more than one remote.
