BREAKING CHANGE: compiler will throw on binding to non-existing properties.
Till now it was possible to have a binding to a non-existing property,
ex.: `<div [foo]="exp">`. From now on this is compilation error - any
property binding needs to have at least one associated property:
eaither on an HTML element or on any directive associated with a
given element (directives' properites need to be declared using the
`properties` field in the `@Directive` / `@Component` annotation).
Closes#2598
These wrappers are not natively understood by
ts2dart. Removing them will improve Dart2JS
compilation due to fewer megamorphic calls to List
functions.
It also makes Angular code more succinct and
improves type safety in Angular due to better type
inference of the Array component type.
This change exposed several bugs in Angular.
Closes#2472Closes#2339
BREAKING CHANGE
- `Compiler.compile` has been removed, the only way to compile
components dynamically is via `Compiler.compileInHost`
- `DynamicComponentLoader.loadIntoExistingLocation` has changed:
* renamed into `loadIntoLocation`
* will always create the host element as well
* requires an element with a variable inside of the host component view
next to which it will load new component.
- `DynamicComponentLoader.loadNextToExistingLocation` was renamed into
`DynamicComponentLoader.loadNextToLocation`
- `DynamicComponentLoader.loadIntoNewLocation` is removed
* use `DynamicComponentLoader.loadNextToLocation` instead
and then move the view nodes
manually around via `DomRenderer.getRootNodes()`
- `AppViewManager.{create,destroy}Free{Host,Embedded}View` was removed
* use `AppViewManager.createViewInContainer` and then move the view nodes
manually around via `DomRenderer.getRootNodes()`
- `Renderer.detachFreeView` was removed. Use `DomRenderer.getRootNodes()`
to get the root nodes of a view and detach them manually.
Enable pregenerated (for Dart) and JIT (for Js) change detectors when
possible. Previously we would always use `DynamicChangeDetector`s, but
these cause megamorphic calls and are therefore much slower.
Closes#502
- Modify change detectors to `throw` when attempting to detect changes
on a dehydrated detector.
- Modify `DynamicChagneDetector` to use `null` for the `context` of a
dehydrated detector.
clang-format 1.0.17 substantially improves formatting for fat arrow functions
and array literal detection. It also fixes a number of minor formatting issues.
Update the compile benchmark to allow the Dart transformer to properly
generate the getters, setters, & methods needed.
This also improves the method of duplicating the source templates,
further decreasing runtime from ~5s to ~2s.
Also consolidates metadata handling in `ElementInjector`
BREAKING CHANGE:
- renames `DirectiveMetadataReader` into `DirectiveResolver`
and removes `src/core/compiler/directive_metadata`.
Fixes#1712Fixes#1713
The goal is to make implementing a renderer straight forward.
BREAKING_CHANGE:
- Renderer interface was redone / simplified.
- `DirectDomRenderer` was replaced by `DomRenderer`.
- `DirectDomRenderer.setImperativeComponentRootNodes` is replaced
by the following 2 steps:
1. `ViewManager.getComponentView(elementRef) -> ViewRef`
2. `DomRenderer.setComponentViewRootNodes(viewRef, rootNodes)`
- all `@View` annotations need to have a template, but the template
may be empty. Previously views that had a `renderer` property did
not have to have a `template`.
- `dynamicComponentLoader.loadIntoNewLocation` does no more allow
to pass an element, but requires a css selector.
Special syntax: `:document` can be used as prefix to search globally
on the document instead of in the provided parent view.
Part of #1675
In 'angular2/di' the symbol:
- Inject is a decorator
- InjectAnnotation is an annotation
Internally one an get a hold of annotations without *Annotations appened
(to make ts2dart work without workarounds) by importing from
'angular2/src/di/annotations_impl' instead of 'angular2/di'. This is
needed only for users that transpile through TS and through ts2dart.
BREAKING CHANGE:
Previously, `Directive` was the abstract base class of several directives.
Now, `Directive` is the former `Decorator`, and `Component` inherits from it.
BREAKING_CHANGE:
- The special type of `Viewport` directives is removed
in favor of a more general `Decorator` directive
- `ViewContainerRef` now no more has a default `ProtoViewRef`
but requires an explicit one when creating views.
Closes#1536
BREAKING CHANGES:
- `NgElement` merged into `ElementRef`
- `Compiler.compile…` returns `ProtoViewRef`
- `ViewContainer` uses `ProtoViewRef`s and `ViewRef`s.
- `ViewRef`/`ProtoViewRef` in renderer were renamed to
`RenderViewRef`/`RenderProtoViewRef`.

AppViewManager is the single entry point to changing the view hierarchy.
It is split between the manager itself which does coordination and
helper methods, so both are easily testable in isolation.
Also, ViewContainer is now only a pure reference to a bound element
with the previous functionality but does not contain the list of views
any more.
Part of #1477
Major changes:
- `compiler.compileRoot(el, type)`
-> `compiler.compileInHost(type) + viewHydrator.hydrateHostViewInPlace(el, view)`
- move all `hydrate`/`dehydrate` methods out of `View` and `ViewContainer` into
a standalone class `view_hydrator` as private methods and provide new public
methods dedicated to the individual use cases.
Note: This PR does not change the current functionality, only moves it
into different places.
See design discussion in #1351, in preparation for imperative views.
Add two factory static functions to Injector: resolveAndCreate and
fromResolvedBindings.
We want to avoid resolution and flattening every time we create a new
injector. This commit allows the user to cache resolved bindings and
reuse them.
Introduces angular2/src/core/compiler/ViewFactory which
extracts ProtoView.instantiate and replaces ViewPool.
Note: This is a work in progress commit to unblock other commits.
There will be follow ups to add unit tests, remove TODOs, …
- Allow pub (build|serve) to specify mode
- Update pubbuild.js & pubserve.js to allow the caller to provide a `mode` value.
- Update settings to allow the di benchmark to be transformed to run statically.
We do this as we are seeing flakes in Chrome with ECONNREFUSED.
Also reuses the same browser window.
Also reenables the infinite scroll benchmark
Closes#1137
Now, running protractor configs by default only runs e2e tests. If
the --benchmark flag is added, it runs only the perf tests, and always
restarts the browser in between tests. If the --dryrun test is added,
the perf tests are run only once.
This should make it easier to run perf tests versus example e2e tests,
and help stabilize the travis build because perf tests always
run with a clean browser.
The `e2e_test` folder in `angular2` never contained e2e tests but was
used to store utilities for writing e2e/perf tests. A better place for
them is `angular2/src/test_lib`.
Closes#855
Export files are now directly under the module folder,
e.g. `core/core.js`. With this, an import like `core/core`
won’t need a path mapping (e.g. via `System.paths`) any more.
This adds the `src` folder to all other import statements as well.
modules/angular has no implementation, but depends on all the pieces
that make angular - core, di, directives, etc. It is the package that
all client apps will depend on.
Event emitters can be injected into Directives. Event emitters take over
browser events with the same name. Emitted events do not bubble. Event
emitters can be injected even if there is no corresponding callback in
the template.
Use as follows:
@Decorator(...)
class MyDec(@EventEmitter('click') clickEmitter) {
...
fireClick() {
var eventData = {...};
this._clickEmitter(eventData);
}
}
- adds console and cloud reporter (via Google BigQuery).
- makes parameters of tests explicit and modifiable.
- removes `detect` and `ignoreGc` mode from benchpress
as these can result in unstable numbers.
Shows the metrics:
script, render, gcAmount, gcAmountInScript, gcTime
Run modes:
- detect: auto detect whether to force gc
- forceGc: forces a gc before every run and ignores no runs
- noGcInScript: ignore runs that have gc while a script was executing
- plain: does not force gc nor ignore runs
Closes#368
Major changes:
- make API more reusable
- format output nicely
- only force gc if needed
Regarding forcing gc:
Forcing gc can change script execution time.
We now don't force gc at first and ignore results where gc happens during script execution.
When we ignored too many results, we switch to forcing gc.
Closes#339
