test($rootScope): add assertion to test ensuring that NaN -> NaN does not throw

2014-03-21T20:05:29+00:00

https://github.com/angular/angular.js/commit/fb6062fb9d83545730b993e94ac7482ffd43a62c implements a
fix for NaN values causing $watchCollection to throw an infdig error. This change updates the test
by adding an assertion which explains what is actually being tested a bit better, and may also
provide better information in the event that the test ever fails.

Closes #6758

docs(tutorial): correct spelling mistake

2014-03-21T20:05:29+00:00

docs($document): add a documentation example.

2014-03-21T20:05:29+00:00

The $document docs are pretty empty, and this fills them out a bit. The example itself may not be
particularly useful, but it could be improved or removed later. Works for me.

Closes #6757

docs($q): add mention of Antroid 2.x browser

2014-03-21T20:05:29+00:00

The Android 2.x browser is not ES5-compatible in that it does not allow
use of reserved words as property names. This docs fix adds Android to the
note to the `$q` docs which already make it known that string property
notation should be used when using the `finally` method on `$q`.

fix($rootScope): ng-repeat can't handle NaN values. #4605

2014-03-21T20:05:29+00:00

$watchCollection checks if oldValue !== newValue which does not work for NaN. This was causing
infinite digest errors, since comparing NaN to NaN in $watchCollection would always return false,
indicating that a change was occuring on each loop.

This fix adds a simple check to see if the current value and previous value are both NaN, and
if so, does not count it as a change.

Closes #4605

fix(orderBy): support string predicates containing non-ident characters

2014-03-21T20:05:29+00:00

The orderBy filter now allows string predicates passed to the orderBy filter to make use property
name predicates containing non-ident strings, such as spaces or percent signs, or non-latin
characters.

This behaviour requires the predicate string to be double-quoted.

In markup, this might look like so:

```html

...

```

Or in JS:

```js
var sorted = $filter('orderBy')(array, ['"Tip %"', '-"Subtotal $"'], false);
```

Closes #6143
Closes #6144

fix(ngCookie): convert non-string values to string

2014-03-21T20:05:29+00:00

Previously, non-string values stored in $cookies would be removed, without warning the user, and
causing difficulty debugging. Now, the value is converted to string before being stored, and the
value is not dropped. Serialization may be customized using the toString() method of an object's
prototype.

Closes #6151
Closes #6220

fix(ngTouch): update workaround for desktop Webkit quirk

2014-03-21T20:05:29+00:00

Fix click busting of input click triggered by a label click quickly
following a touch event on a different element, in desktop
and mobile WebKit

To reproduce the issue fixed by this commit set up a page with
 - an element with ng-click
 - a radio button (with hg-model) and associated label
In a quick sequence tap on the element and then on the label.
The radio button will not be checked, unless PREVENT_DURATION has passed

Closes #6302
