Creating a complex event doesn't update the calendar view

[bnjbvr]

STR

• Create a new event, click on "More details"
• Complete some fields
• Click on create

Expected

The new event should directly show up in the calendar view.

Actual

One needs to refresh the page to see the newly created event in the calendar.

Hi benjamin,

This works on my cozy's VM, but after looking at the code it appears to work only because of the realtime loop (the change is made in the Data-System, an event is fired, the app fetch latest version from the server).

To test if the realtime loop works on your VM, open the calendar app in two browser windows on the same month and create an event in one of the window. It should appears without refresh on the other window.

If it doesn't, that means the realtime doesn't work.
To debug it :

• Can you see the websocket connection in your browser debugger ?
• Are you hosted on cozy or self-hosting ? if self-hosting, could you give me your node & stack versions
  sudo cozy-monitor versions node -v
• cat /usr/local/cozy/apps/data-system/data-system/cozy-data-system/log/production.log | grep "Publishin g event."
  should not be empty

Hi!
Indeed, realtime loop doesn't seem to work:

• The websocket is apparently not working (both firefox and chromium):

Chromium:

WebSocket connection to 'wss://cozy.mydomain.net/socket.io/1/websocket/dWgJD1rckfbAz8ENp1r4' failed: Error during WebSocket handshake: Unexpected response code: 200 

Firefox:

Firefox can't establish a connection to the server at wss://cozy.mydomain.net/apps/calendar/socket.io/1/websocket/xR09M9UAThA6c6ocqCeX.

• sudo cozy-monitor versions

Cozy Stack:
controller: 1.0.25
data-system: 1.0.12
home: 1.0.21
proxy: 1.0.2
indexer: 1.0.0
monitor: 1.0.0

• node -v
v0.10.26
• There are "Publishing event" lines in the log (my instance is self hosted)
  For what it's worth, simple events get created and show up directly on the current window.

Oh, and thanks by the way, there are some chances we've found a bug in Firefox that shows up in the Calendar app :) (not related to the websocket though)

Any update on that matter @aenario / @bnjbvr ?

[aenario]

@bnjbvr , you need to update your proxy.

[bnjbvr]

@aenario I updated proxy and the issue is still present. According to cozy-monitor versions, proxy is at version 1.0.4, which seems to be the head version on the github repo. Is there something else I can do to help debugging?

[aenario]

Ok , It works on my hosted instance with the following versions.

Cozy Stack:
controller: 1.0.24
data-system: 1.0.12
home: 1.0.11
proxy: 1.0.4
monitor: 1.1.17

Another potential source of error is your nginx (or another reverse proxy you might use). It needs to be setup for websockets (details here : http://nginx.org/en/docs/http/websocket.html)

[bnjbvr]

Thanks for the links! After pasting the following lines in the cozy nginx descriptor file, everything worked as expected (after an actual nginx restart, sigh):

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

It might be nice to set up a FAQ page and to add a link to this nginx doc page there. Feel free to close the issue according to what decision you take :)

[aenario]

I created an issue in cozy-docs and closing this one. Thanks for reporting !
