Crash in 1.0.7 - BUG IN CLIENT OF LIBDISPATCH: trying to lock recursively about atinternet-apple-sdk HOT 15 CLOSED

We have to use corporate fonts for the LiveTagging/SmartTracker SDK. We don't use them for the standard Tracker. In fact we used to have this bug in early development stage and it disappeared until today :/
Do you have an idea of why this bug happens ?

from atinternet-apple-sdk.

Why are you using corporate font ? They should be lazy loaded as needed.

I'm investigating it today I will keep you up to date.

@d-theo I think it's might be due to race condition on init.

@mackoj I saw a lot of strange hacks related to CGFontCreate like this : http://www.openradar.me/18778790 with ppl end up by calling
_ = UIFont() or other UIFont methods before calling CGFontCreate()

Unfortunately I am having trouble reproducing the bug

Il will try this fix thanks

from atinternet-apple-sdk.

I have modified ATInternet-Apple-SDK/ATInternetTracker/Sources/Tracker.swift in registerFont with _ = UIFont() at the beginning.

I hope this hack can solve this bug. In addition we will release a fix to load the fonts only if the liveTagging feature is enabled

from atinternet-apple-sdk.

I think if it continue to crash to just remove this function until you provide a fix.

from atinternet-apple-sdk.

any update about the issue ?

from atinternet-apple-sdk.

Please stop using ! everywhere this is why it crash because fontRef was bad and force unwrapped...

    func registerFont(_ font: String) {
      _ = UIFont()
      guard
        let fontPath = Bundle(for: Tracker.self).path(forResource: font, ofType: ".ttf"),
        let dataFont = NSData(contentsOfFile: fontPath),
        let provider = CGDataProvider(data: dataFont)
        else { return }

      let fontRef = CGFont(provider)
      CTFontManagerRegisterGraphicsFont(fontRef, nil)
    }

We will make it right for the next release around next week, and with better lazy-loading ;)

I have to admit that I complain a lot and about a lot of things but it's really great that your SDK is open source because it allow me to made a fix when I need it and it priceless...

from atinternet-apple-sdk.

no problem, it allows us to improve too ;)
In fact we are always happy to take PR (even if our workflow does not allow to merge them into github)

Closed: patched with your code
