$log conflicts with other code that messes with console

[oliversalzburg]

I converted our Cordova application to use $log only to realize afterwards, that I no longer get any log output when debugging iOS.

I realized that this is due to the fact that console.log is replaced and redirected to my debugger, but $log will still use the "old" console.log which isn't redirected.

I couldn't see a simple way to get $log to use the redirected console.log functions, so I'm asking for suggestions on how to handle this. For now, I'm just going to revert back to calling console.log directly.

It is interesting that this happens since in the $log service, we always lookup the console object on the $window object. I am wondering how Cordova is monkey-patching console... If it was doing something like:

window.console = cordovaConsole;

Then I think this should just work.

I suspect that instead they are either modifying the window object completely or the global namespace that is provided to cordova JavaScript applications is not the window object but some other container object that provides its own console object.

@oliversalzburg - perhaps you could step into the $logProvider and see what exactly the $window object is and also find out what the global object is inside a cordova app.

@ajoslin - any thoughts?

I think Cordova is asynchronously monkey patching it on deviceready.

You could try listening to document's deviceready event then override $log's functions again.

If Cordova is doing it synchronously, you could also make sure you're including Cordova before angular and that would fix it.

See this line:
https://github.com/angular/angular.js/blob/master/src/ng/log.js#L136

The call to logConsole is acquiring the console object from $window on each call.

function consoleLog(type) {
  var console = $window.console || {},
  logFn = console[type] || console.log || noop,
  ...

So I think that this means that $window is not the global object that is being provided to cordova apps at runtime.

I just tried to look up the code again (I originally looked into this issue a few weeks ago) and the problem comes from the org.apache.cordova.console plugin and, more specifically, https://github.com/apache/cordova-plugin-console/blob/master/www/console-via-logger.js. But I couldn't wrap my head around specifics right now, sorry.

From what I can tell, I really have no control over inclusion order in my Cordova application, but I might be mistaken.
