Description

When running the code below, a deadlock warning intermittently appears: Apr 4 14:59:27 unknown UIKitApplication:com.appcelerator.timob8193[0x13cc][3489] : [WARN] Timing out waiting on main thread. Possibly a deadlock? in TiThreadPerformOnMainThread (TiBase.m:238) Attempted to reproduce in 2.0.0.GA, but could not. Steps to Reproduce: 1. Run code.

var win1 = Ti.UI.createWindow({  
    title:'Win 1',
    layout:'vertical',
    backgroundColor:'#fff'
});
 
var vw1 = Ti.UI.createView({
    layout:'horizontal',
    backgroundColor:'red',
    width:'100%',
    height:75
});
win1.add(vw1);
 
//
var TheOrange=Ti.UI.createView({height:75,
                                width:'160dp',
                                backgroundColor:'orange',
                                top:0
                               });
 
var GreenView=Ti.UI.createView({
          height:Ti.UI.SIZE,
          width:Ti.UI.SIZE,
          focusable:false,
          touchEnabled:false,
          backgroundColor:'green'
});
 
GreenView.add(TheOrange);
vw1.add(GreenView);
 
var BlueView=Ti.UI.createView({
    backgroundColor:'blue',
    width:50,
    height:50
});
vw1.add(BlueView);
//
 
win1.open();

Expected Result: Views should appear without deadlock warnings. Actual Result: Views appear with deadlock warning, intermittent.

I receive the same warning when running a newly-built module for iOS (generated as per the modules guide using 2.1.0, without making any changes or additions): [WARN] Timing out waiting on main thread. Possibly a deadlock? in TiThreadPerformOnMainThread (TiBase.m:238)

I received the same warning when using a table within a standard window. Appears intermittently in a few other places as well.

Same problem when running on iPad [DEBUG] application booted in 553.596020 ms [WARN] Timing out waiting on main thread. Possibly a deadlock? in TiThreadPerformOnMainThread (TiBase.m:238) The app is only showing a white screen or the splash screen. Sometimes my index.js file is loaded after waiting 2-3 minutes for the splash screen but the app is not responding/loading completely.

I am also experiencing this issue after using 2.0.2GA SDK from 1.8.2. Our app takes more time to start than before and its having this error message. {quote} 2012-06-12 10:28:59.104 What Happen[88198:207] -[UITabBarController setSelectedViewController:] only a view controller in the tab bar controller's list of view controllers can be selected. [WARN] Timing out waiting on main thread. Possibly a deadlock? in TiThreadPerformOnMainThread (TiBase.m:238) {quote}

Am also receiving this error. More than what could be classed as intermittently too. Does any one know if this will prevent app store submission?

These warnings have been removed from production builds in 2.1.0. They are only useful for internal developers.

Closing as fixed. Tested and verified with: Titanium Studio, build: 2.1.0.201206251749 Titanium SDK: 2.1.0.v20120626104306 Device: iPad 3rd gen (5.1.1) Views appear without deadlock warnings.
