`for in` is much faster than `Object.keys()` but `for in` includes properties from the prototype.

All the uses of shallowCopy don't deal with objects with heavy prototypes, except for Attributes instances
in $compile.
For this reason it's better to special-case Attributes constructor and make it do it's own shallow copy.
This cleans up the Attribute/$compile code as well.
We no longer have a need for this feature that was added to primarily support
$watchGroup (see previous commit).
BREAKING CHANGE: deregisterNotifier callback for $watch is no longer available
This api was available only in the last few 1.3 beta versions and is not
very useful for applications, so we don't expect that anyone will be affected
by this change.
Instead of using a counter and an extra watch, just schedule the reaction function via .
This gives us the same/similar ordering and coalecsing of updates as counter without the extra
overhead. Also the code is easier to read.
Since interpolation uses watchGroup, this change additionally improves performance of interpolation.
In large table benchmark digest cost went down by 15-20% for interpolation.

Some libraries (like jQuery UI) patch jQuery.cleanData as well. This commit
makes Angular work correctly even if such external patching was done after
the Angular one.
Fixes#8471
Add a $route#updateParams method for changing the current route
parameters without having to build a URL and call $location#path.
Useful for apps with a structure involving programmatically moving
between pages on the current route, but with different :param
values.
Properties in the object passed to $route.updateParams() will be
added to the location as queryParams if not contained within the
route's path definition.
In some scenarios you want to be able to specify properties on the event
that is passed to the event handler. JQuery does this by overloading the
first parameter (`eventName`). If it is an object with a `type` property
then we assume that it must be a custom event.
In this case the custom event must provide the `type` property which is
the name of the event to be triggered. `triggerHandler` will continue to
provide dummy default functions for `preventDefault()`, `isDefaultPrevented()`
and `stopPropagation()` but you may override these with your own versions
in your custom object if you wish.
In addition the commit provides some performance and memory usage
improvements by only creating objects and doing work that is necessary.
This commit also renames the parameters inline with jQuery.
Closes#8469
Using `prop` to set selected is correct programmatically but accessibility
guidelines suggest that at least on item should have the `selected` attribute
set.

@kevinjamesus86 noticed that the input control would trigger a $digest
cycle every time it was blurred, adcc5a00bf (commitcomment-7129512).
After the control is in a $touched state, other $digest cycles are
unnecesary.
Closes#8450
The $submitted state changes
- to true when the form is submitted
- to false when $setPristine is called on the form
A .ng-submitted class is added to the form when $submitted=true
Closes#8056
The data jQuery method was re-implemented in 2.0 in a secure way. This made
current hacky Angular solution to move data between elements via changing the
value of the internal node[jQuery.expando] stop working. Instead, just copy the
data from the first element to the other one.
Testing cache leaks on jQuery 2.x is not possible in the same way as it's done
in jqLite or in jQuery 1.x as there is no publicly exposed data storage. One
way to test it would be to intercept all places where a jQuery object is created
to save a reference to the underlaying node but there is no single place in the
jQuery code through which all element creation passes (there are various
shortcuts for performance reasons). Instead we rely on jqLite.cache testing
to find potential data leaks.
BREAKING CHANGE: Angular no longer supports jQuery versions below 2.1.1.
Previously, absent a specified target attribute, when clicking on an anchor tag with an href beginning
with either "javascript:" or "mailto:", the framework would rewrite the URL, when it ought not to.
With this change, the browser is prevented from rewriting if the URL begins with a case-insensitive match
for "javascript:" or "mailto:", optionally preceeded by whitespace.

A regression #7855 was introduced by
dc149de936
This test ensures that reverting that commit fixes this regression.
In the regression, changes to a bound model in ng-change were not propagated back to the view.
Test for #7855
An earlier commit dc149de936 caused an error where the first option of
a select would be skipped over if it had a blank disabled value. These tests demonstrate that with
that commit in place, blank disabled options are skipped in a select. When the commit is reverted,
the correct behavior is seen that the blank disabled option is still selected in both selects
marked with required and those that have optional choices.
Relates to #7715
Commit dc149de936 was reverted to fix regressions #7715 and #7855.
This commit introduced this test case and a corresponding fix for preventing the update of the
selected property of an option element on a digest with no change event. Although the previous fix
introduced regressions, the test covers a valid issue and should be included.
This reverts commit dc149de936. That commit fixes a bug caused by
Firefox updating `select.value` on hover. However, it
causes other bugs with select including the issue described in #7715. This issue details how
selects with a blank disabled option skip to the second option. We filed a bug
with Firefox for the problematic behavior the reverted commit addresses
https://bugzilla.mozilla.org/show_bug.cgi?id=1039047, and alternate Angular fixes are being
investigated.
Closes#7715#7855
Some servers require characters within path segments to contain semicolons,
such as `/;jsessionid=foo` in order to work correctly. RFC-3986 includes
semicolons as acceptable sub-delimiters inside of path and query, but $location
currently encodes semicolons. This can cause an infinite digest to occur since $location
is comparing the internal semicolon-encoded url with the semicolon-unencoded url returned
from window.location.href, causing Angular to believe the url is changing with each digest
loop.
This fix adds ";" to the list of characters to unencode after encoding queries or path segments.
Closes#5019
Previously we defaulted just to A because of IE8 which had a hard time with applying css styles to HTMLUnknownElements.
This is no longer the case with IE9, so we should make restrict default to EA. Doing so will make it easier to create
components and avoid matching errors when creating new directives
BREAKING CHANGE: directives now match elements by default unless specific restriction rules are set via `restrict` property.
This means that if a directive 'myFoo' previously didn't specify matching restrictrion, it will now match both the attribute
and element form.
Before:
<div my-foo></div> <---- my-foo attribute matched the directive
<my-foo></my-foo> <---- no match
After:
<div my-foo></div> <---- my-foo attribute matched the directive
<my-foo></my-foo> <---- my-foo element matched the directive
It is not expected that this will be a problem in practice because of widespread use of prefixes that make "<my-foo>" like
elements unlikely.
Closes#8321
This potentially helps lead the way towards a more performant fly-weight implementation, as discussed
earlier in the year. Using a constructor means we can put things in the prototype chain, and essentially
treat $q as a Promise class, and reuse methods as appropriate.
Short of that, I feel this style is slightly more convenient and streamlined, compared with the older
API.
Closes#8311Closes#6427 (I know it's not really the solution asked for in #6427, sorry!)
ngRepeat can now alias the snapshot of the list of items evaluated after all filters have
been applied as a property on the scope. Prior to this fix, when a filter is applied on a
repeater, there is no way to trigger an event when the repeater renders zero results.
Closes#5919Closes#8046Closes#8282
If an ngSwitchWhen or ngSwitchDefault directive is on an element that also
contains a transclusion directive (such as ngRepeat) the new scope should
be the one provided by the bound transclusion function.
Previously we were incorrectly creating a simple child of the main ngSwitch
scope.
BREAKING CHANGE:
** Directive Priority Changed ** - this commit changes the priority
of `ngSwitchWhen` and `ngSwitchDefault` from 800 to 1200. This makes their
priority higher than `ngRepeat`, which allows items to be repeated on
the switch case element reliably.
In general your directives should have a lower priority than these directives
if you want them to exist inside the case elements. If you relied on the
priority of these directives then you should check that your code still
operates correctly.
Closes#8235
- updated the internal jqLite helpers to use the low-level jqLite.data/removeData to avoid unnecessary jq wrappers and loops
- updated $compile to use the low-level jqLite.data/removeData to avoid unnecessary jq wrappers at link time
With the removal of regular expression support `ngList` no longer supported
splitting on newlines (and other pure whitespace splitters).
This change allows the application developer to specify whether whitespace
should be respected or trimmed by using the `ngTrim` attribute. This also
makes `ngList` consistent with the standard use of `ngTrim` in input directives
in general.
