UserCP Screeching Frog 0.7603

Still working on tweaking the list of users in live chat.
  • Added new code in update() hook for testing.

Code:
updated() {
    this.updateCount++;        // initially set to zero in data()
    if (this.updateCount % 5 === true || this.updateCount == 2) {
      this.getHereNow();
    }
    //console.log("update count", this.updateCount);
  },

It is interesting to console.log() the updateCount var.

For this page, after the initial page mount, updateCount == 2, so I set the logic to call this.getHereNow(); (again) testing, as it was also called when the page was first mounted (so this is a test, not final answer).

Then I noticed if we receive a new pubnub message the count is incremented by around 5. So for fun, I set this.updateCount % 5 == true but this is really just overkill, because I also call the same method when a message is received. so if I go with this kind of approach, using the view update() lifecycle hook, then I can get rid of the calls to the same method in other parts of the code and control the logic from update().

The problem I am trying to solve is that sometimes when a user enters live chat (that also includes "self"), their occupancy and name (uuid) does not appear correctly above the message window. As soon as a message is processed, all is updated because I call getHereNow() when a message is received.

Of course, if I setpubnub.subscribe() presence TRUE, this problem can be easily solved, but then the API pings the pubnub network every second or so, flooding the network with presence pings from the browser. This is not scaleable.

Hence, the best way forward, in my view, is for PubNub to include a new configuration timer in the pubnub.subscribe() so we can control the frequency of the pubnub presence pings (polling) in the browser.

Or maybe I am just missing some more obvious way in the PubNub SDK to do this more correctly?!

NAME
mdimport, mdimport32 -- import file hierarchies into the metadata datastore. SYNOPSIS
mdimport [-VXLArgn] [-d level | category] [-w delay] file | directory mdimport32 [-VXLArgn] [-d level | category] [-w delay] file | directory DESCRIPTION
mdimport is used to test Spotlight plug-ins, list the installed plug-ins and schema, and re-index files handled by a plug-in when a new plug- in is installed. mdimport32 is used in exactly the same way, but for 32 bit plugins. The following options are available: -g plugin Load the plugin at the provided path, ignoring system installed plugins. Useful for testing plugins that have not yet been installed. -V Print timing information for this run of mdimport. -A Print out the list of all of the attributes and their localizations in the current language and exit. -X Print the schema file and exit -r Ask the server to reimport files for UTIs claimed by the listed plugin. For example, the following would cause all of the chat files on the system to be reimported: mdimport -r /System/Library/Spotlight/Chat.mdimporter -p Print out performance information gathered during the run. -L Print the list of installed importers and exit. -d level Print debugging information. Level can be 1-4. -n Don't actually set the attributes on the file. Useful for debugging. -w msecs Wait for the specified interval between scanning files. NOTES
The -f switch is obsolete in Leopard and beyond. SEE ALSO
