Missing longpoll events error

[malc_b]

Sorry this is in english

I'm getting red toast messages saying missing longpoll events since recent upgrades.  Searching seems to come up with any number of suggestions for what the meta tags in the head should be set to so I don't know if this is the problem.  The details on github do not seemed to have changed so could we have a definitive example there of what the metatags should be so I can exclude that.

It would also be useful on github to mention that csrfToken=none and longpoll=websocket are needed as attributes for web.

[malc_b]

BTW console reports no longpoll for 19-23 minutes, (i.e. 1000+ seconds).  Web browser has been in background sometime too.

[setstate]

Thats okay. Browser-Tabs in the background doesn't receive updates. The HealthCheck triggers restart longpoll, if the last update is too old. We can discuss about the alert toast, but the restart is okay.
Maybe it's better, just to pop up an info toast instead of the alert. 

[malc_b]

Thanks for the reply.

I don't think it is a real timeout.  Here is a captured console message

No longpoll event since 1486197329.505secondes -> restart polling

And that was about 30s max after opening the browser window and I didn't shift away from that window

Scrolling back through console here is another message

Longpoll last event before: 17201 day(s) 8 hour(s) 37 minute(s) 29 second(s)

I don't think the timer is actually running.

[malc_b]

I can't seem to find where

ftui.poll.lastEventTimestamp

is set to the last poll time.  I'm looking with chrome dev tools and ftui.poll.lastEventTimestamp always seems to be 1970.  Hence I'm seeing a missing longpoll event each time health check runs.

According to console ftui.poll.lasteEventTimestamp and lastUpdateTimestamp are both 1970.  Only ftui.poll.lastShortpollTimestamp is showing current date and time.

BTW I mean that I can see line 1050 sets ftui.poll.lastEventTimestamp to new date (i.e. current time) but code never gets there.

UPDATE:

OK, so I need to change something on the screen before update runs.  That then sets lastUpdateTimestamp to current time.  But health check is still running so eventually unless I change something more it will throw up an error.  The logic is wrong with this check or update should run from a timer and not just when the user interacts.

[setstate]

Seems that longpoll doesn't work. Is it configured? Does you page contain devices which send update events. Load index_state.html to check longpoll settings.

[malc_b]

Attached is the screen shot of index_state.html

I do have devices like MAX rad valves but they don't change that often.  Do I need a dummy AT to force a changing state?

This is my index.html head

  <meta name='longpoll' content='1'> <!-- 1=longpoll;0=shortpoll every 30sec -->
  <meta name='debug' content='2'> <!-- verbose level 1-6 = output to console;0 = not output -->
  <meta name='longpoll_type' content='websocket'>

[setstate]

If you feel certain that longpoll works and your only problem is the low frequency of update events, then you could change the meta tag "longpoll_maxage" and  increase the value to your need or set it to 0 to disable the age check.

[malc_b]

I'll try that.  BTW should you not be setting longpoll last update to the current time when it is created?  Otherwise first healthcheck throws an error if no update has occurred.  Below is my log after "empty cache and hard reload".  I've set maxage to zero which supresses the errors but console still reports them.  I've also created a heart dummy and a heartbeat at to toggle heart.  This toggles every 25s to give fhem some activity.  It's not on the current page I'm looking at in ftui so is that why this has helped?  And what is the #2a2a2a?
