Hi there I'm having a few issues in the newest versions of MT, mostly around Threading (ok, ALL around threading).
this one is a fairly major, but easy to work around, one for me: https://bugzilla.xamarin.com/show_bug.cgi?id=3676 I'm getting it when I use NewtonSoft Json.net from a thread. I worked around it by using it from the UI thread, and caching the resulting object (not a big deal at all in this case). The DLL I'm using hasn't changed for a long time..... However, I'm also having an issue with TestFlight's logging. If I log in a thread, sometimes, I get a segfault. Not every time, but always in the same place, and ALWAYS in a thread. The thread code is like this: Task.Factory.StartNew(() => { CalculateSummary (); }).ContinueWith(t => { if (oncomplete != null) oncomplete(); }, new UIKitScheduler()); (UIKitScheduler is this: https://gist.github.com/1431457 ) CalculateSummary loads a bunch of stuff from SQLite, then the last line is: Util.Log ("recalculating took {0}ms".Fmt (sw.ElapsedMilliseconds)); It is possible that the oncomplete is throwing an error, which I need to check out - I've had issues with threading disappearing if the continue throws an uncaught exception. Anywho, Util.Log does a Debug.WriteLine (or Console.WriteLine, same result), and a TestFlight.Log. The first works always. The latter crashes _sometimes_, usually if he app is busy - ie, I'm moving between screens (which triggers calculations) etc. But sometimes just if it's sitting idle. I've tried putting the logging into a InvokeOnMainThread, but with the same result. I wasn't using TF before, but I've not had the Json problem in previous versions (I have a lot of production code out there which is working doing this). That said, I wasn't using Tasks before (I was using the threadpool), which may also be it! Any ideas? did this change after 5.2.4 (I'm on 5.2.8 I think at the moment) I have a semi-stacktrace thing, but it has almost no actual info in it. I'm going to try a debug build tonight, and see if I can get more info out. console just shows that the app segfaulted (error 11 I think??) Outside of that, everything is exceptionally delicious with iOS5, the appearance API's, and the Task API's :) N -- Nic Wise t. +44 7788 592 806 | @fastchicken | http://www.linkedin.com/in/nicwise b. http://www.fastchicken.co.nz/ Nearest Bus: find when the next bus is coming to your stop. http://goo.gl/Vcz1p mobileAgent (for FreeAgent): get your accounts in your pocket. http://goo.gl/IuBU Trip Wallet: Keep track of your budget on the go: http://goo.gl/ePhKa London Bike App: Find the nearest Boris Bike, and get riding! http://goo.gl/Icp2 _______________________________________________ MonoTouch mailing list [email protected] http://lists.ximian.com/mailman/listinfo/monotouch
