Array.prototype.sort is speced out to be as potentionally unstable sort,
which is how it's implemented in FF and IE. This has caused the order
of directives with the same priority to vary between browsers.
For consistency sake, we now consider directive name and registration,
order when determining the order of directives with the same priority.
Note: it is still possible to get into a situation when the directive
order is underministic - when source files are loaded asynchronously
in non-deterministic order and there are are directives registered
with the same name and priority, the order in which they will be applied
will depend on the file load order.
The routeUtils.js file was declaring a number of functions that were
leaking into other modules such as ngMocks causing tests to pass
incorrectly.
Closes#4360
The location service, and other portions of the application,
were relying on a complicated regular expression to get parts of a URL.
But there is already a private urlUtils provider,
which relies on HTMLAnchorElement to provide this information,
and is suitable for most cases.
In order to make urlUtils more accessible in the absence of DI,
its methods were converted to standalone functions available globally.
The urlUtils.resolve method was renamed urlResolve,
and was refactored to only take 1 argument, url,
and not the 2nd "parse" boolean.
The method now always returns a parsed url.
All places in code which previously wanted a string instead of a parsed
url can now get the value from the href property of the returned object.
Tests were also added to ensure IPv6 addresses were handled correctly.

Issue: multi-elements ng-repeat (ng-repeat-start, ng-repeat-end) can contain elements with a trancluding directive. This directive changes content of the row (template) and ng-repeat does not work correctly (when removing/moving rows), because ng-repeat works with the original template (elements).
This changes ng-repeat behavior to traverse the DOM to find current elements everytime we are moving/removing rows (if the template has multiple elements).
Closes#3104
Since c785267e jqLite uses setAttribute (rather than className property) in order to change classes. Some elements (eg. Comment) do not have this method which blows up.
jQuery silently ignores these method calls (because it uses className), so to get the same behavior as jQuery, we check for setAttribute method first.
This reverts commit 3a65822023.
The change cased regressions in third party components that require
promises from getter functions not to be unwrapped.
Since we have deprecated the promise unwrapping support in $parse it
doesn't make much sense to fix this issue and deal with regressions in
third party code.
Closes#4158
This commit disables promise unwrapping and adds
$parseProvider.unwrapPromises() getter/setter api that allows developers
to turn the feature back on if needed. Promise unwrapping support will
be removed from Angular in the future and this setting only allows for
enabling it during transitional period.
If the unwrapping is enabled, Angular will log a warning about each
expression that unwraps a promise (to reduce the noise, each expression
is logged only onces). To disable this logging use
`$parseProvider.logPromiseWarnings(false)`.
Previously promises found anywhere in the expression during expression
evaluation would evaluate to undefined while unresolved and to the
fulfillment value if fulfilled.
This is a feature that didn't prove to be wildly useful or popular,
primarily because of the dichotomy between data access in templates
(accessed as raw values) and controller code (accessed as promises).
In most code we ended up resolving promises manually in controllers
or automatically via routing and unifying the model access in this way.
Other downsides of automatic promise unwrapping:
- when building components it's often desirable to receive the
raw promises
- adds complexity and slows down expression evaluation
- makes expression code pre-generation unattractive due to the
amount of code that needs to be generated
- makes IDE auto-completion and tool support hard
- adds too much magic
BREAKING CHANGE: $parse and templates in general will no longer
automatically unwrap promises. This feature has been deprecated and
if absolutely needed, it can be reenabled during transitional period
via `$parseProvider.unwrapPromises(true)` api.

The trigger handler event in jqLite takes an event object as a second
parameter, but jQuery requires an array of parameters. This is causing
the touchend event to not come thtough in the click handler when jQuery
is loaded.
Existing documentation implies that an Event object should be available
as `$event` on swipe directives, which previously was only working for
`ng-click`.
Closes#4071Closes#4321
`checkboxInputType` and `ngList` directives need to have special logic for whether
they are empty or not. Previously this had been hard coded into their
own directives or the `ngRequired` directive. This made it difficult to handle
these special cases.
This change factors out the question of whether an input is empty into a method
`$isEmpty` on the `ngModelController`. The `ngRequired` directive now uses this
method when testing for validity and directives, such as `checkbox` or `ngList`
can override it to apply logic specific to their needs.
Closes#3490, #3658, #2594
The $interval service simplifies creating and testing recurring tasks.
This service does not increment $browser's outstanding request count,
which means that scenario tests and Protractor tests will not timeout
when a site uses a polling function registered by $interval. Provides
a workaround for #2402.
For unit tests, repeated tasks can be controlled using ngMock$interval's
tick(), tickNext(), and tickAll() functions.
This reverts commit 281feba4ca.
Since Lexer and Parser objects are stateful it is not safe
to reuse them for parsing of multiple expressions.
After recent refactoring into prototypical style, the instantiation
of these objects is so cheap that it's not a huge win to use
singletons here.
Objects received from outside AngularJS may have had their `hasOwnProperty`
method overridden with something else. In cases where we can do this without
incurring a performance penalty we call directly on Object.prototype.hasOwnProperty
to ensure that we use the correct method.
Also, we have some internal hash objects, where the keys for the map are provided
from outside AngularJS. In such cases we either prevent `hasOwnProperty` from
being used as a key or provide some other way of preventing our objects from
having their `hasOwnProperty` overridden.
BREAKING CHANGE: Inputs with name equal to "hasOwnProperty" are not allowed inside
form or ngForm directives.
Before, inputs whose name was "hasOwnProperty" were quietly ignored and not added
to the scope. Now a badname exception is thrown.
Using "hasOwnProperty" for an input name would be very unusual and bad practice.
Either do not include such an input in a `form` or `ngForm` directive or change
the name of the input.
Closes#3331
Prevent the obj.$delete instance method from sending the resource as the request body. This commit uses the existing hasBody boolean to only set httpConfig.data for methods which should have a request body.

This reduces memory consumption of parsed angular expressions and
speeds up parsing.
This JSPerf case demonstrates the performance boost:
http://jsperf.com/closure-vs-prototype-ngparser
Chrome: 1.5–2x boost
FF: slightly slower (I would love to know why)
IE: 4x boost

of expressions as demostrated in this JSPerf:

previously the compile/link fns executed in this order controlled via priority:
- CompilePriorityHigh, CompilePriorityMedium, CompilePriorityLow
- PreLinkPriorityHigh, PreLinkPriorityMedium, PreLinkPriorityLow
- link children
- PostLinkPriorityHigh, PostLinkPriorityMedium, PostLinkPriorityLow
This was changed to:
- CompilePriorityHigh, CompilePriorityMedium, CompilePriorityLow
- PreLinkPriorityHigh, PreLinkPriorityMedium, PreLinkPriorityLow
- link children
- PostLinkPriorityLow, PostLinkPriorityMedium , PostLinkPriorityHigh
Using this order the child transclusion directive that gets replaced
onto the current element get executed correctly (see issue #3558),
and more generally, the order of execution of post linking function
makes more sense. The incorrect order was an oversight that has
gone unnoticed for many suns and moons.
(FYI: postLink functions are the default linking functions)
BREAKING CHANGE: the order of postLink fn is now mirror opposite of
the order in which corresponding preLinking and compile functions
execute.
Very few directives in practice rely on order of postLinking function
(unlike on the order of compile functions), so in the rare case
of this change affecting an existing directive, it might be necessary
to convert it to a preLinking function or give it negative priority
(look at the diff of this commit to see how an internal attribute
interpolation directive was adjusted).
Closes#3558
Previously we would stop the compilation for both regular and element
transclusion directives which was wrong. Only element transclusion directives
should be terminal.
The `angular.bind` function reflects the definition of "partial application", which
reduces a function's arity rather than transforming a function with n args into a
chain of n functions, each having a single arg.
curry : f(x,y,z) -> f(x)(y)(z)
partial application : f(x,y,z) -> f(x)(y,z)

The current comment of Attributes.$observe doesn't state correctly the behavior when the attribute contains no interpolation. Specifically, it states that the observer function will never be invoked if the attribute contains no interpolation. However, the actual behavior in this case is that the observer will be invoked once during the next digest loop.
Fix wrong behaviour that didn't allow 'data-on' and 'on' element attributes
to be interpolated by $compile. The regex now accepts any string beginning
with 'on' and with at least one more English letter.
This is a breaking change. To migrate to the new behavior,
delete or set headers to `undefined` to avoid having them sent.
To restore the old behavior, override `$httpBackendProvider`
with the old implementation.
Closes#2984
The `XMLHttpRequest.send` spec defines different semantics for `null`

How did compiling a templateUrl (async) directive with `replace:true` work before this commit?
1/ apply all directives with higher priority than the templateUrl directive
2/ partially apply the templateUrl directive (create `beforeTemplateNodeLinkFn`)
3/ fetch the template
4/ apply second part of the templateUrl directive on the fetched template
(`afterTemplateNodeLinkFn`)
That is, the templateUrl directive is basically split into two parts (two `nodeLinkFn` functions),
which has to be both applied.
Normally we compose linking functions (`nodeLinkFn`) using continuation - calling the linking
function of a parent element, passing the linking function of the child elements as an argument. The
parent linking function then does:
1/ execute its pre-link functions
2/ call the child elements linking function (traverse)
3/ execute its post-link functions
Now, we have two linking functions for the same DOM element level (because the templateUrl directive
has been split).
There has been multiple issues because of the order of these two linking functions (creating
controller before setting up scope locals, running linking functions before instantiating
controller, etc.). It is easy to fix one use case, but it breaks some other use case. It is hard to
decide what is the "correct" order of these two linking functions as they are essentially on the
same level.
Running them side-by-side screws up pre/post linking functions for the high priority directives
(those executed before the templateUrl directive). It runs post-linking functions before traversing:
```js
beforeTemplateNodeLinkFn(null); // do not travers
afterTemplateNodeLinkFn(afterTemplateChildLinkFn);
```
Composing them (in any order) screws up the order of post-linking functions. We could fix this by
having post-linking functions to execute in reverse order (from the lowest priority to the highest)
which might actually make a sense.
**My solution is to remove this splitting.** This commit removes the `beforeTemplateNodeLinkFn`. The
first run (before we have the template) only schedules fetching the template. The rest (creating
scope locals, instantiating a controller, linking functions, etc) is done when processing the
directive again (in the context of the already fetched template; this is the cloned
`derivedSyncDirective`).
We still need to pass-through the linking functions of the higher priority directives (those
executed before the templateUrl directive), that's why I added `preLinkFns` and `postLinkFns`
arguments to `applyDirectivesToNode`.
This also changes the "$compile transclude should make the result of a transclusion available to the
parent directive in post- linking phase (templateUrl)" unit test. It was testing that a parent
directive can see the content of transclusion in its pre-link function. That is IMHO wrong (as the
`ngTransclude` directive inserts the translusion in its linking function). This test was only passing because of
c173ca4128, which changed the behavior of the compiler to traverse
before executing the parent linking function. That was wrong and also caused the #3792 issue, which
this change fixes.

In the Android browser, the BFCache maintains
the state of JavaScript applications even when
navigating to another app, so that going
forward and back, to and from an application
is very fast.
Unfortunately, this can have undesired side
effects. In this instance, the location
variable was holding a reference to a stale
window.location, and was throwing errors
when going back to an Angular app after
browsing to another site.
This fix makes sure that location.url()
includes a check to make sure that location
is referencing the current window.location.

jqLite previously used `elt.className` to add and remove classes from a DOM Node, but
because the className property is not writable on SVG elements, it doesn't work with
them. This patch replaces accesses to `className` with `get/setAttribute`.
`classList` was also considered as a solution, but because only IE10+ supports it, we
have to wait. :'(
The JqLiteAddClass/JQLiteRemoveClass methods are now also used directly by $animate
to work around the jQuery not being able to handle class modifications on SVG elements.
Closes#3858
The problem was in keeping the values of `attrNameStart` and `attrNameEnd` between directive loop iterations which lead to the compiler looking for multi-element ranges for any directives that happened to be in the directive list after one that was applied on a range. For instance, having a ng-repeat-start and ng-class on a single element with ng-repeat being resolved first made the compiler look for an ng-repeat-end for both ng-repeat and ng-class because the `attrNameEnd` was not reset to a falsy value before the second iteration. As the result, an exception saying the block end element could not be found and the second directive was not actually applied.

I have this sinking feeling that support this use case sort of
encourages binding to function that blindly trust some html. For now,
I'm fixing the issue while I think about the use cases some more.
In the case of a function that performs any non-trivial work before
wrapping the value (e.g. the showdown filter in issue #3980, or the
binding to a simply wrapper function in issue #3932 if it did anything
meaty), this fix makes it "work" - but performance is going to suck -
you should bind to some other thing on scope that watches the actual
source and adjusts itself when that changes (e.g. the showdown filter.)
For the case of the wrapper in #3932, if one isn't performing
sanitization or some such thing - then you the developer has insight
into why that value is safe in that particular context - and it should
be available simply by name and not as a result of a function taking any
arbitrary input to make auditing of security a little saner.
Closes#3932, #3980
BREAKING CHANGE: ngInclude's priority is now set to 1000

Firefox 23 has deprecated the use of createEvent for transition and
animation events. We must now use `new TransitionEvent()` and
`new AnimationEvent()` if they are available.
But of course IE doesn't support this format correctly so we must wrap
the attempt in a try block and revert to document.createEvent if necessary..
onAnimationProgress now checks the event's elapsedTime property before
checking the originalEvent.elapsedTime property.
Use browserTrigger with elapsedTime parameter to trigger animation events
BREAKING CHANGE: browserTrigger now uses an eventData object instead of direct parameters for mouse events.
To migrate, place the `keys`,`x` and `y` parameters inside of an object and place that as the third parameter
for the browserTrigger function.
It was not clear what you could pass to specify modules to load in the
`module` parameter of this function. The `modules` parameter takes an
array.
The main case is to provide a String, which is the name of a "predefined"
angular module.
The side cases are to provide a Function (or an annotated function in the
form of an Array), which will be invoked by the injector as a run block.
It is not possible to "define" new modules via this parameter.
