Commit 5d1b323. re-enabled the user presence updates and notifications.
Unfortunately, it showed poor performance due to the high frequency of bus
notifications triggered on our instance (~600k users).
In this rev., we don't trigger notifications on presence changes anymore, but
we rather send the presence of users we have a DM open with, at the end of each
poll period. For performance reasons, we ensure not to do that more than once
every 30 seconds.
We also refined the detection of the 'away' status client side. 'Last presence'
timestamps are stored in the local storage, and the current inactivity period
is sent at each poll. Those presence timestamps now rely on browser activity
detection (click, keypress... events) rather than on the focus on Odoo tabs.
Finally, we removed the no more necessary cron introduced in 5d1b323.
Before this rev., no notification was sent on the bus when the user presence
changed. Thus, the bullets displayed in Discuss were never updated and stayed
as they were on the initialilization of the chat_manager (on webclient launch).
This rev. makes the bus.presence notifications work, and handles them client
side.
Moreover, the disconnections detection is now performed at each poll (with a
maximum of 1 per minute), instead of randomly (1/100 chance) at each poll, as
it scales better than the former solution. We also added a cron that performs
this check every 5 minutes. It is needed to detect that the last connected user
just disconnected (useful for visitors in the website, trying to talk with a
livechat operator).
Also, the 'away' status is now handled client side, as it makes more sense
that way (being away at each poll, e.g. every 50seconds, during 10 minutes
doesn't mean that we didn't come back between two polls).
Finaly, in bus.js, CrossTabBus, we moved the code writing in/reading the local
storage after the tab registration as this code depends on the fact that the
tab is the master tab or not (and this is known only once the tab is
registered).
This rev. was necessary in stable because the livechat uses the user status to
detect if there is an operator available, and this was often inaccurate.
Moreover, it improves the user experience of the chat in the backend.
In test mode, only one cursor is available, and longpolling will take
it, and not give it back before 60s, causing a phantomjs timeout. This
commit simply return an error when the server is in test mode.
Sadly, I had to patch the web client to prevent logging the error in
this case, because that's the way phantomjs detect if there is a
problem.
- im_chat.session will be replaced by mail.channel
- im_chat.shortode is renamed into mail.shortcode
- im_chat.presence is moved to bus module
- js and controller code is moved from im_chat to mail module
This commit only move files, and modify manifests, bundles, ... The code will be adapt in the next commits.
Migrate the models and controller to new API. Renaming xml id according to convention, renaming openerp tag into odoo tag. Add comment strings and documentations.
