Tracker RichMedia refresh never sent

[xploit42]

Hello,
We are using AtInternet/Tracker to track RichMedia events. As advised in the documentation we send event synchronously on an Analytics Queue.
Recently we experienced issues with the refresh events, they are no longer sent.
In DynamicRefresh.swift I set breakpoints in start() and process(). It stops in start but process() is never executed.
It seems we encounter this issue since we updated to Xcode 12.
A workaround is to send the sendPlay(dynamicRefreshConfiguration: ) on MainThread.

Hi,

Can you share some parts of your tagging code ?

I created a sample code that reproduces our issue

import Tracker

class ATInternetDebug {

    let tracker: Tracker
    lazy var mediaPlayer: MediaPlayer = tracker.mediaPlayers.add()
    let queue = DispatchQueue(label: "analytics")
    var audio: RichMedia?

    init() {
        tracker = ATInternet.sharedInstance.tracker(AppConstants.ATInternet.trackerName,
                                                    configuration: AppConstants.ATInternet.trackerConfiguration)
        tracker.enableDebugger = true
        setupRichMedia()
    }

    func setupRichMedia() {
        audio = mediaPlayer.media.add("label",
                                      mediaTheme1: "theme1",
                                      mediaTheme2: "theme2",
                                      mediaType: "type",
                                      duration: 42)
    }

    func sendPlay() {
        queue.sync {
            audio?.sendPlay(dynamicRefreshConfiguration: [0: 10])
        }
    }
}

I tested it by calling sendPlay() for both main en global() as following

        // With this one I don't get the refresh events
        DispatchQueue.global().async {
            self.atDebugger.sendPlay()
        }
        
        // With this one I get the refresh events
        DispatchQueue.main.async {
            self.atDebugger.sendPlay()
        }

I only have the refresh events when calling my function on main thread.

In both case at timer initialisation (DynamicRefresh.swift L29) we are on our custom serial queue (analytics).

Hope this can help

Hum, the problem is SDK is not safe for concurrent use and global() queue use concurrency unfortunately

[xploit42]

The events are sent by our player which is on another DispatchQueue, it will never be sent on the main thread. This is why in my sample I dispatched on global().

In my sendPlay() func I dispatch on my "analytics" serial queue, this should work doesn't it?
