tidev / ti.worker Goto Github PK

I found a problem after repeating my background process several times during a normal use. (The user click on a ListView, the bg process starts/ends, a new window is open)

The module gets stuck right after

[_bridge evalJSWithoutResult:@"TiWorkerStart__();"]; in the booted method:

- (void)booted:(id)bridge
{
  // this callback is called when the thread is up and running
  dispatch_async(_serialQueue, ^{
    _booted = YES;
    NSLog(@"[INFO] Worker %@ (0x%X) is running", [_selfProxy url], self);
    [_selfProxy setExecutionContext:_bridge];
    [[NSFileManager defaultManager] removeItemAtPath:_tempFile error:nil];
  });

  // start our JS processing
  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
      [_bridge evalJSWithoutResult:@"TiWorkerStart__();"]; // STUCK HERE
  });
}

usually the postMessage method is what happens after, but not in some cases.

If you attempt to load a worker from a bad source location, it doesn't give any indication or error.

I am unable to log to the console within the worker file. Ti.API.info throws a parse error.

Does the Android implementation of ti.worker still run code on UI thread ?

https://jira.appcelerator.org/browse/MOD-2351

Just fyi... I was following the example but it wasn't working... but when I did a setTimeout() with 1 millisecond for posting to the task, it worked.

Thanks btw -- this is great and what I've been waiting for for Titanium!

I am getting a crash on the following code when posting data back from the worker.

-(void)postMessage:(id)msg
{
    ENSURE_SINGLE_ARG(msg,NSObject); 
    // this is from the worker, posting back to the creator
    NSDictionary *dict = [NSDictionary dictionaryWithObject:msg forKey:@"data"];
    TiWorkerProxy *proxy = (TiWorkerProxy*)_parent;
    [proxy fireMessageEvent:dict];
}

Is there a limit to the size of data that can be sent back?

works fine on ios<6

on 6 - SDK 2.1.3
KrollBridge.mm line 598

[self evalFile:[url path] callback:self selector:@selector(booted)];

url is nil: (supposed ti be the wrapped javascript) ...

When there is a syntax error in the worker file, the debug message in the console provides an incorrect/obfuscated source file.

Eg:
sourceURL = "file://localhost/var/folders/jb/b8vsmqzx00ng22t1383j_qfr0000gn/T/5694";

I have a problem with large database sincronization beacouse it's blocking user interface on iOs phones.
So it is posibble to add background task support to iOS so the database operations dont block the UI.

Just wondering if there was an android equivalent to this module.

Many thanks.
