From: Daniel Henrique Barboza <danielhb@linux.vnet.ibm.com>
This patch makes backend and UI changes to implement the asynchronous
UI notification in WoK.
- Backend:
A push server was implemented from scratch to manage the opened websocket
connections. The push server connects to the
/run/user/<user_id>/woknotifications UNIX socket and broadcasts all messages
to all connections.
The websocket module is the same module that exists in the Kimchi
plug-in. The idea is to remove the module from Kimchi and make it
use the module from WoK. ws_proxy initialization was also added
in src/wok/server.py.
A change were made in Wok base control classes to allow every
call of log_request to also send a websocket notification in
the following format:
<METHOD>:/<plugin>/<entity>/<action>
For example, creating a new user in Ginger would trigger the
following websocket notification:
'POST:/ginger/users'
- Frontend:
In ui/js/wok.main.js two new functions were added to help the
usage of asynchronous notifications in the frontend. The idea:
a single websocket is opened per session. This opened websocket
will broadcast all incoming messages to all listeners registered.
Listeners can be added by the new wok.addNotificationListener()
method. This method will clean up any registered listener by
itself when the user changes tabs/URL.
The single websocket sends heartbeats to the backend side each
30 seconds. No reply from the backend is issued or expected. This
heartbeat is just a way to ensure that the browser does not
close the connection due to inactivity. This behavior varies from
browser to browser but this 30 second heartbeat is more than enough
to ensure that the websocket is kept alive.
- Working example in User Log:
A simple usage is provided in this patch. Changes were made in the
UI of the User Log feature to refresh the listing each time a new
log entry websocket notification is received. The idea is to allow
this code to be a working example of how other tabs can consume
the asynchronous notifications.
