We are working to introduce a general core API for presence, which will clash with this plugin's `/presence` namespace
This commit introduces no functional change. There may be a slight interruption in discourse-presence functionality during a deploy of this commit.
Before this commit, the presence state of users were stored on the
server side and any updates to the state meant we had to publish the
entire state to the clients. Also, the way the state of users were
stored on the server side meant we didn't have a way to differentiate
between replying users and whispering users.
In this redesign, we decided to move the tracking of users state to the client
side and have the server publish client events instead. As a result of
this change, we're able to remove the number of opened connections
needed to track presence and also reduce the payload that is sent for
each event.
At the same time, we've also improved on the restrictions when publishing message_bus messages. Users that
do not have permission to see certain events will not receive messages
for those events.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
- Added guardian checks to endpoint
- Added security to messagebus publishing
- Added specs for security measures
- Moved all logic into component
- Stop sending ‘keepAlive’ messages if the user stops editing for more then 2 minutes
- Enable plugin by default
