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.
In apps that create lots of scopes (apps with large tables) the uid generation
shows up in the profiler and adds a few milliseconds. Using simple counter
doesn't have this overhead.
I think the initial fear of overflowing and thus using string alphanum sequence
is unjustified because even if an app was to create lots of scopes non-stop,
you could create about 28.6 million scopes per seconds for 10 years before
you would reach a number that can't be accurately represented in JS
BREAKING CHANGE: Scope#$id is now of time number rather than string. Since the
id is primarily being used for debugging purposes this change should not affect
anyone.
`log.empty()` is the same as `log.reset()`, except thati `empty()` also returns the current array with messages
instead of:
```
// do work
expect(log).toEqual(['bar']);
log.reset();
```
do:
```
// do work
expect(log.empty()).toEqual(['bar']);
```
jQuery's elem.html('') is way slower than elem.empty(). As clearing
element contents happens quite often in certain scenarios, switching
to using .empty() provides a significant performance boost when using
Angular with jQuery.
Closes#4457
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
