Won't Load Previous Messages #358

Loading previous messages continues spinning and never loads previous messages:

The text was updated successfully, but these errors were encountered:

scouttyg · 2014-05-12T22:59:19Z

Have you pulled in the latest? I know there was an issue there before that should have been solved in #350.

Does the rails server log report any errors?

johnjelinek · 2014-05-12T23:00:29Z

No errors logged that I can tell, I have the latest. What's the file path I
should be watching?

The filepath to watch for logging if on development would be development.log (ie, tail -f log/development.log from the main Kandan directory.

As for why it's not loading earlier messages, it's hard to tell. Did you try different browsers? Are you running it on a nonstandard configuration? (I know you have another issue on running it with Phusion Passenger and nginx -- could it be related to that?)

johnjelinek · 2014-05-12T23:42:33Z

I'll check development.log, in this case I'm just using thin+nginx. Running
in chrome on windows.

@scouttyg I'm not finding a log/development.log path. Is it supposed to be in kandan/ or something like /var/log/...?

johnjelinek · 2014-05-13T19:08:01Z

Here's my kandan/ tree:

(suppressed to save space)
616 directories, 1573 files

johnjelinek · 2014-05-13T19:18:43Z

Looks like logs only print to STDOUT in development: https://github.com/kandanapp/kandan/blob/master/config/environments/development.rb#L38-L41. In which case, according to the output there, I don't notice any related errors:

It might be best to watch your rails server and see if you see any errors run through it. IE clear it right before you trigger the earlier messages (command K on Mac), then see what it looks like. Mine looks like this for example:

Perhaps the errors are all client side, and these errors aren't being sent to the server for logging:

scouttyg · 2014-05-13T19:39:11Z

It very well might be issues with Faye.

When you hit earlier messages, you should see a method kind of like mine that I listed:

IE the app should be hitting ActivitiesController#Index with an "oldest" parameter (it's querying for earlier messages). If it's not doing that, there might be something bigger at play there.

johnjelinek · 2014-05-13T20:15:14Z

It seems like the issue goes away when I don't have nginx in front of kandan ... maybe nginx is messing up Faye? Sounds like my other issue: #355 but without Passenger this time.

johnjelinek · 2014-05-14T17:37:48Z

@scouttyg I made a discovery. It seems to be isolated to when my browser is a certain height. I have vertical monitors so my browser real-estate is:

> window.innerWidth
1206
> window.innerHeight
1809

If I bring down the size of the window, scroll to the bottom, and then begin to scroll up, then messages begin to load.

scouttyg · 2014-05-14T17:54:47Z

That's actually good to hear, because I was definitely getting stumped. I'll check it out and see if I can replicate that!

scouttyg · 2014-05-14T18:06:35Z

Ah, I think I figured it out -- so Kandan by default only shows the last X messages, and at the top of the container has a "Loading more messages" div constantly there. The idea being that as a user scrolls up, it will trigger the load of more messages. The code for that is:

    $container.bind 'scroll', =>
      if $container.scrollTop() <= 100 && !@loading_new_messages
        @loading_new_messages = true
        @loadMoreActivities($container)
      return

It binds the "load more activities" action to the scroll as you can see. The issue with that is that if you're able to load all the activities in your window at once to display (ie, a vertical display, or if you are zoomed out enough), there will be nothing to scroll -- so the "load more activities" action doesn't get loaded.

I'll see if I can fix this.

johnjelinek · 2014-05-14T18:08:14Z

Also noticed that on initial load at this browser size, the chat does not go all the way down to the bottom. After I resize and scroll down, then scroll up, and re-maximize, it all gets fixed.

Notice in my example, the initial admin disconnected message does not reach the bottom, but at the end of the gif, it does reach the bottom.

scouttyg · 2014-05-14T18:10:12Z

As a temporary fix for this, you should be able to change the file config/kandan_settings.yml to have a per_page option of something larger (that will load enough messages to give you a scrollbar initially). It's not a perfect fix, but it should work for now while I see if there is a better way.

Fixed container so that it would load extra messages if it detected that... #361
