Previously if the collection model was set to undefined on the first digest,

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
It's quite rare for anyone to depend on explicity directive priority,
but if a custom directive that needs to run before ngInclude exists,
it should have its priority checked and adjusted if needed.
Closes#3793
- Add proper ngdoc annotations to existing $observe documentation
- Add link to directive guide for usage example of $observe
- Add note about $observe function parameter signature
Closes#3957
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.
Closes#3692
It's great that IE11 wants to be compatible enough that it doesn't want
to be special cased and treated differently.
However, as long as one has to have a different code path for IE than
for the other supported browsers, we still need to detect and special
case it. For instance, our URL parsing code still needs the same
workaround the we used for IE10. We still see the same Access denied /
TypeError exceptions when setting certain values. FYI, Angular doesn't
generally blindly test for IE – we also check the version number.
Thanks to modern.ie for the free IE11 test VM.

This reverts commit 42af8eada2.
This turned out to be a bad idea as it prevents us from moving the
time forward and asserting that the component state didn't change
due to the scheduled task executing too early.
Remove obsolete locale files that are not found in Google Closure library.
I don't know why they were removed, but without a link to Closure we can't
maintain these files going forward so I'm deleting them.
BREAKING CHANGE: some non-common region-specific local files were removed.
This change causes a new $digest to be scheduled in the next tick if
a task was was sent to the $evalAsync queue from outside of a $digest
or an $apply.
While this mode of operation is not common for most of the user code,
this change means that $q promises that utilze $evalAsync queue to
guarantee asynchronicity of promise apis will now also resolve outside
of a $digest, which turned out to be a big pain point for some developers.
The implementation ensures that we don't do more work than needed and
that we coalese as much work as possible into a single $digest.
The use of $browser instead of setTimeout ensures that we can mock out
and control the scheduling of "auto-flush", which should in theory
allow all of the existing code and tests to work without negative
side-effects.
Closes#3539Closes#2438
When $timeout#flush is called with a delay and no task can be flushed within that
delay, the current time should not be updated as that gets the mock into an inconsistent
state.
BREAKING CHANGE: if a tests was written around the buggy behavior the delays might be off now
This would typically not be a problem, but because of the previous breaking change in
$timeout.flush, the combination of two might be confusing and that's why we are documenting
it.
Old behavior:
```
doSomething(); //schedules task to execute in 500ms from now
doOtherStuff(); //schedules task to execute in 600ms from now
try {
$timeout.flush(300); // throws "no task to be flushed" exception
} catch(e) {};
$time.flush(200); //flushes only doSomething() task
```
New behavior:
```
doSomething(); //schedules task to execute in 500ms from now
doOtherStuff(); //schedules task to execute in 600ms from now
try {
$timeout.flush(300); // throws "no task to be flushed" exception
} catch(e) {};
$time.flush(200); // throws "no task to be flushed" exception again
// because previous exception didn't move the time forward
```
Fixed test:
```
doSomething(); //schedules task to execute in 500ms from now
doOtherStuff(); //schedules task to execute in 600ms from now
try {
$timeout.flush(300); // throws "no task to be flushed" exception
} catch(e) {};
$time.flush(500); // flushes only doSomething() task
```
When calling $timeout.flush with or without a delay an exception should
be thrown if there is nothing to be flushed.
This prevents tests from flushing stuff unnecessarily.
BREAKING CHANGE: calling $timeout.flush(delay) when there is no task to be flushed
within the delay throws an exception now.
Please adjust the delay or remove the flush call from your tests as the exception
is a signed of a programming error.
ngAnimate causes a 1ms flicker on the screen when no CSS animations are present on the element.
The solution is to change $animate to only use $timeouts when a duration is found on the element
before the transition/keyframe animation takes over.

This reverts commit 637c9b1611.
(ref #3633 and #3646)
The minimum bar for $sce is IE8 in standards mode. IE7 standards mode
is not supported. If you must support IE7, you should disable $sce
completely.
angular.module('ie7support', []).config(function($sceProvider) {
// Completely disable SCE to support IE7.
$sceProvider.enabled(false);
});
Currently, the documentation does a bad job of explaining the distinction between the services that it provides,
and the module itself. Furthermore, the instructions for using optional modules are inconsistent or missing.
This commit addresses the problem by ading a new `{@installModule foo}` annotation to the docs generator that
inlines the appropriate instructions based on the name of the module.
it wasn't clear before that if given the same name a second time this method RETRIEVES an EXISTING module. Not even sure if my description is accurate, hoping someone will either confirm and merge or clear it up.
Closes#3666
Changes documentMode test version to 7 in order to support IE 8 in IE 7 standards

when the transluded content is being teleported to the translusion point, we should ensure that
the translusion point is empty before appending otherwise we end up with junk before the transcluded
content
previously the translusion was appended the the ngTranslude element via
$evalAsync which makes the transluded dom unavailable to parent
post-linking functions. By appending translusion in linking phase,
post-linking functions will be able to access it.
Code was evaluating !expression[key] while attempting to
see if the key was present, but this was evaluating to true for
false values as well as missing keys.
Closes#2797.
Make sure $timeout callbacks are forgotten about immediately after
execution or cancellation.
Previously when passing invokeApply=false, the cleanup used $q and so
would be pending until the next $digest was triggered. This does not
make a large functional difference, but can be very visible when
looking at memory consumption of an app or debugging around the
$$asyncQueue - these callbacks can have a big retaining tree.
After a recent refactoring using $location in the default hashbang mode would result
in hash url being initialized unnecessarily in cases when the base url didn't end
with a slash.
for example http://localhost:8000/temp.html would get rewritten as
http://location:8000/temp.html#/temp.html by error.
Added new route matching capabilities:
- optional param
Changed route matching syntax:
- named wildcard
BREAKING CHANGE: the syntax for named wildcard parameters in routes
has changed from *wildcard to :wildcard*
To migrate the code, follow the example below. Here, *highlight becomes
:highlight*:
Before:
$routeProvider.when('/Book1/:book/Chapter/:chapter/*highlight/edit',
{controller: noop, templateUrl: 'Chapter.html'});
After:
$routeProvider.when('/Book1/:book/Chapter/:chapter/:highlight*/edit',
{controller: noop, templateUrl: 'Chapter.html'});
This fixes regression introduced by #3514 (5c560117) - this commit is being
reverted here and a better fix is included.
The regression caused the controller to be instantiated before the isolate scope
was initialized.
Closes#3493Closes#3482Closes#3537Closes#3540
BREAKING CHANGE: the `always` method has been renamed to `finally`.
The reason for this change is to align `$q` with the Q promises library,
despite the fact that this makes it a bit more difficult to
use with non-ES5 browsers, like IE8.
`finally` also goes well together with `catch` api that was added to
$q recently and is part of the DOM promises standard.
To migrate the code follow the example below:
Before:
$http.get('/foo').always(doSomething);
After:
$http.get('/foo').finally(doSomething);
or for IE8 compatible code:
$http.get('/foo')['finally'](doSomething);
Nothing would prevent a user from accidentally calling angular.bootstrap on an element that had already been bootstrapped. If this was done, odd behavior could manifest in an application, causing different scopes to update the same DOM, and causing debugger confusion.
This fix adds a check inside of angular.bootstrap to check if the passed-in element already has an injector, and if so, will throw an error.
BREAKING CHANGE: since all the code in the ngMobile module is touch related,
we are renaming the module to ngTouch.
To migrate, please replace all references to "ngMobile" with "ngTouch" and
"angular-mobile.js" to "angular-touch.js".

Controllers should be always instantiated after compile fn runs, but before
pre-link fn runs. This way, controllers are available to pre-link fns that
request them.
Previously this was broken for async directives (directives with templateUrl).
Closes#3493Closes#3482Closes#3514
<form name="ctrl.form"> form controller will accessible
as $scope.ctrl.form instead of $scope['ctrl.form']
BREAKING CHANGE:
If you have form names that will evaluate as an expression:
<form name="ctrl.form">
And if you are accessing the form from your controller:
Before:
function($scope) {
$scope['ctrl.form'] // form controller instance
}
After:
function($scope) {
$scope.ctrl.form // form controller instance
}
This makes it possible to access a form from a controller
using the new "controller as" syntax. Supporting the previous
behavior offers no benefit.
The input field email regex does't not match long domain extensions. This commit extends the email regexp to take a 6 character TLD.

- To avoid hacking test method of RegExp
- Optionally overwrite `toString` method of fn to show validation tips

Closes: #2981
This fixes an inconsistency where you can't call the setter function
when the expression resolves to a top level field name on a promise.
Setting a field on an unresolved promise will throw an exception. (This
shouldn't really happen in your template/js code and points to a
programming error.)
Closes#1827
Ghost clicks are busted but the corresponding form elements are still focused. This means that for example on smartphones the soft keyboard will be opened. This pull request prevents the unwanted opening of the soft keyboard.
The global jQuery reference is removed by angular scenario and only a local scoped reference is kept. To make jQuery available for other code, a new reference angular.scenario.jQuery is added.
Normally $exceptionHandler doesn't throw an exception. It is normally
used just for logging and so on. But if an application developer
implemented a version that did throw an exception then $q would never
have called reject() when converting an exception thrown inside a `then`
handler into a rejected promise.
When using $resource you must setup your actions carefully based on what the server returns.
If the server responds to a request with an array then you must configure the action with
`isArray:true` and vice versa. The built-in `get` action defaults to `isArray:false` and the
`query` action defaults to `isArray:true`, which is must be changed if the server does not do this.
Before the error message was an exception inside angular.copy, which didn't explain what the
real problem was. Rather than changing the way that angular.copy works, this change ensures that
a better error message is provided to the programmer if they do not set up their resource actions
correctly.
Closes#2255, #1044
Change the implementation of isArrayLike to use one heavily based on the

If ngClass fires off an add- or removeClass whilst the opposite animation is going on then
the animation will be skipped. The default behavior of ngClass was executing remoteClass
with an empty string while addClass had just fired. This commit fixes that bug.
BREAKING CHANGE: previously ngView only updated its content, after this change
ngView will recreate itself every time a new content is included. This ensures
that a single rootElement for all the included contents always exists, which makes
definition of css styles for animations much easier.
BREAKING CHANGE: previously ngInclude only updated its content, after this change
ngInclude will recreate itself every time a new content is included. This ensures
that a single rootElement for all the included contents always exists, which makes
definition of css styles for animations much easier.
- ngAnimate directive is gone and was replaced with class based animations/transitions
- support for triggering animations on css class additions and removals
- done callback was added to all animation apis
- $animation and $animator where merged into a single $animate service with api:
- $animate.enter(element, parent, after, done);
- $animate.leave(element, done);
- $animate.move(element, parent, after, done);
- $animate.addClass(element, className, done);
- $animate.removeClass(element, className, done);
BREAKING CHANGE: too many things changed, we'll write up a separate doc with migration instructions
the $timeout mock's flush method allows flushing queued up requests
but doesn't allow to for checking with what delay a task was queued
up. flushNext flushes the next queued up task and can asserts the
scheduled delay.
Similar to ngMobile clicks, these events were not capturable by other
directives. Now they emit 'swipeleft' and 'swiperight' events that can
be follow with element.on('swipeleft', ...).
Changes:
- remove ng-bind-html-unsafe
- ng-bind-html is now in core
- ng-bind-html is secure
- supports SCE - so you can bind to an arbitrary trusted string
- automatic sanitization if $sanitize is available
BREAKING CHANGE:
ng-html-bind-unsafe has been removed and replaced by ng-html-bind
(which has been removed from ngSanitize.) ng-bind-html provides
ng-html-bind-unsafe like behavior (innerHTML's the result without
sanitization) when bound to the result of $sce.trustAsHtml(string).
When bound to a plain string, the string is sanitized via $sanitize
before being innerHTML'd. If $sanitize isn't available, it's logs an
exception.
$sce is a service that provides Strict Contextual Escaping services to AngularJS.
Strict Contextual Escaping
--------------------------
Strict Contextual Escaping (SCE) is a mode in which AngularJS requires
bindings in certain contexts to result in a value that is marked as safe
to use for that context One example of such a context is binding
arbitrary html controlled by the user via ng-bind-html-unsafe. We
refer to these contexts as privileged or SCE contexts.
As of version 1.2, Angular ships with SCE enabled by default.
Note: When enabled (the default), IE8 in quirks mode is not supported.
In this mode, IE8 allows one to execute arbitrary javascript by the use
of the expression() syntax. Refer
http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx
to learn more about them. You can ensure your document is in standards
mode and not quirks mode by adding <!doctype html> to the top of your
HTML document.
SCE assists in writing code in way that (a) is secure by default and (b)
makes auditing for security vulnerabilities such as XSS, clickjacking,
etc. a lot easier.
Here's an example of a binding in a privileged context:
<input ng-model="userHtml">
<div ng-bind-html-unsafe="{{userHtml}}">
Notice that ng-bind-html-unsafe is bound to {{userHtml}} controlled by
the user. With SCE disabled, this application allows the user to render
arbitrary HTML into the DIV. In a more realistic example, one may be
rendering user comments, blog articles, etc. via bindings. (HTML is
just one example of a context where rendering user controlled input
creates security vulnerabilities.)
For the case of HTML, you might use a library, either on the client side, or on the server side,
to sanitize unsafe HTML before binding to the value and rendering it in the document.
How would you ensure that every place that used these types of bindings was bound to a value that
was sanitized by your library (or returned as safe for rendering by your server?) How can you
ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
properties/fields and forgot to update the binding to the sanitized value?
To be secure by default, you want to ensure that any such bindings are disallowed unless you can
determine that something explicitly says it's safe to use a value for binding in that
context. You can then audit your code (a simple grep would do) to ensure that this is only done
for those values that you can easily tell are safe - because they were received from your server,
sanitized by your library, etc. You can organize your codebase to help with this - perhaps
allowing only the files in a specific directory to do this. Ensuring that the internal API
exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
In the case of AngularJS' SCE service, one uses $sce.trustAs (and
shorthand methods such as $sce.trustAsHtml, etc.) to obtain values that
will be accepted by SCE / privileged contexts.
In privileged contexts, directives and code will bind to the result of
$sce.getTrusted(context, value) rather than to the value directly.
Directives use $sce.parseAs rather than $parse to watch attribute
bindings, which performs the $sce.getTrusted behind the scenes on
non-constant literals.
As an example, ngBindHtmlUnsafe uses $sce.parseAsHtml(binding
expression). Here's the actual code (slightly simplified):
var ngBindHtmlUnsafeDirective = ['$sce', function($sce) {
return function(scope, element, attr) {
scope.$watch($sce.parseAsHtml(attr.ngBindHtmlUnsafe), function(value) {
element.html(value || '');
});
};
}];
Impact on loading templates
---------------------------
This applies both to the ng-include directive as well as templateUrl's
specified by directives.
By default, Angular only loads templates from the same domain and
protocol as the application document. This is done by calling
$sce.getTrustedResourceUrl on the template URL. To load templates from
other domains and/or protocols, you may either either whitelist them or
wrap it into a trusted value.
*Please note*:
The browser's Same Origin Policy and Cross-Origin Resource Sharing
(CORS) policy apply in addition to this and may further restrict whether
the template is successfully loaded. This means that without the right
CORS policy, loading templates from a different domain won't work on all
browsers. Also, loading templates from file:// URL does not work on
some browsers.
This feels like too much overhead for the developer?
----------------------------------------------------
It's important to remember that SCE only applies to interpolation expressions.
If your expressions are constant literals, they're automatically trusted
and you don't need to call $sce.trustAs on them.
e.g. <div ng-html-bind-unsafe="'<b>implicitly trusted</b>'"></div> just works.
Additionally, a[href] and img[src] automatically sanitize their URLs and
do not pass them through $sce.getTrusted. SCE doesn't play a role here.
The included $sceDelegate comes with sane defaults to allow you to load
templates in ng-include from your application's domain without having to
even know about SCE. It blocks loading templates from other domains or
loading templates over http from an https served document. You can
change these by setting your own custom whitelists and blacklists for
matching such URLs.
This significantly reduces the overhead. It is far easier to pay the
small overhead and have an application that's secure and can be audited
to verify that with much more ease than bolting security onto an
application later.
Previously, no handlers for the click event would be called for the
fast, touch-based ngMobile clicks, only for desktop browser clicks. Now
the event will fire properly for all clicks.

changing the type of select box from single to multiple or the other way around
at runtime is currently not supported and the two-way binding does odd stuff
when such situation happens.
we might eventually support this, but for now we are just going to not allow
binding to select[multiple] to prevent people from relying on something that
doesn't work.
BREAKING CHANGE: binding to select[multiple] directly or via ngMultiple (ng-multiple)
directive is not supported. This feature never worked with two-way data-binding,
so it's not expected that anybody actually depends on it.

- the ngClick attribute was always triggered, regardless the ngDisabled/disabled attributes

Previously, the number filter would format small and large numbers
as scientific notation. It now uses toFixed() to ensure that all
requested digits are shown.
angular.equals was returning inconsistent values for the comparison between
{} and []:
angular.equals({}, []) // true
angular.equals([], {}]) // false
Since these object are not of the same type, they should not be considered
equivalent.
If an app uses HTML5 mode and we open an html5 url on IE8 or 9 which
don't support location href, we use location.replace to reload the page
with the hashbang equivalent of the url but this fails with infinite
digest. This is because location.replace doesn't update location.href
synchronously on IE8 and 9.
Closes#2802, #3305, #1417
ngScenario expects an ngApp directive to be used, and doesn't work for
manually bootstrapped apps. The failure mode is to hang on navigation.
Trying to make this wont-fix bug less obscure by documenting it.
Eventually Protractor will replace ngScenario and fix this.
This code is not being used any more and the test is now failing
due to Karma changes. Karma used to expose window.dump but that
changed recently and that's why our build is now failing.
I'm removing the code and test, but we still need to figure out
how to route window.dump through angular.mock.dump, but that will
have to be a separate commit.
The input [number] error spans did not show on the example, as they were

Ref: 1adf29af13
BREAKING CHANGE: img[src] URLs are now sanitized via a separate
whitelist regex instead of sharing the whitelist regex with a[href].
With this change, img[src] URLs may also be data: URI's matching
mime types image/*. mailto: URLs are disallowed (and do not make
sense for img[src] but were allowed under the a[href] whitelist used
before.)
It is now possible to notify a promise through deferred.notify() method.
Notifications are useful to provide a way to send progress information
to promise holders.
Regular expression objects didn't used to be considered to be equal when using
'angular.equals'. Dirty checking therefore failed to recognize a
property modification.
Closes#2685
Return early in `angular.toJson` if the object to be stringified is `undefined`.
IE8 stringifies `undefined` to `'undefined'` whereas other browsers return
`undefined`. This normalizes behavior and passes currently broken unit tests
in IE8.
The colon character is used to identify parameters in $resource.
This meant that we had to escape the colon used in a port.
It turns out that this is not necessary if we assume that parameter
names cannot consist of only digits.
If the parameter consists only of numbers, then it's a port.
Closes#2778
With select(...).option(val) it previously would select the first node
which contains the value, even if an exact match was available.
This fix prefers exact matches if available, otherwise it reverts
to the previous 'contains' behaviour for backwards compatibility.
Closes#2856
The default fraction size for the number filter is actually computed
from the `NUMBER_FORMATS.PATTERNS.maxFrac` value in the current locale.
Closes#3157
Merely testing for object[key] will give incorrect results on keys
defined in Object.prototype.
Note: IE8 is generally broken in this regard since `for...in` never returns
certain property keys even if they are defined directly on the object.
See #2141 - partially merges this PR
The stock Android browser doesn't support the current for-in body/style
detection for animations and transitions but we can manually fix this.
This is useful for PhoneGap web-views or traditional web-apps using the
stock browser.
Previously an element like
<div class="foo ng-cloak">...</div>
would still be annoyingly visible if it matched a CSS rule like
.foo { display: inline-block; }, overriding ng-cloak's display: none.
Previously if a template contained a directive that had a template
(sync or async) and the directive template was to replace the original
element and the directive template contained another directive on the
root element of this template and this new directive was an element
transclude directive then an infinite recursion would follow because
the compiler kept on re-adding and reapplying the original directive
to the replaced node.
This change fixes that.
Closes#2155
This reverts commit 15e1a29cd0.
The original commit was fixing two issues - one of them was
preventing attributes that triggered directives that replaced
the compiled node to be merged into the new node.
This change was a breaking change (as seen in the diff of the
tests in this commit) and that's why it's being removed.
A proper fix will follow.
parseKeyValue and toKeyValue can now handle duplicate values in the query.
```
?x=1&x=2 <-> {x:[1,2]}
```
The algorithm looks like:
1)parseKeyValue looks for presence of obj[key]
2)detects and replaces obj[key] with [obj[key],val]
3)then pushes more duplicates if necessary
4)toKeyValue decodes array correctly
5)(not changed)$location.search({param: 'key'}) still replaces if necessary
6)(not changed)$location.search({param: ['key1', 'key2']}) sets the url with duplicates
BREAKING CHANGE: Before this change:
- `parseKeyValue` only took the last key overwriting all the previous keys;
- `toKeyValue` joined the keys together in a comma delimited string.
This was deemed buggy behavior. If your server relied on this behavior
then either the server should be fixed or a simple serialization of
the array should be done on the client before passing it to $location.
