BREAKING CHANGES:
- `ShadowDomStrategy` was removed. To specify the encapsulation of a component use `@View(encapsulation: ViewEncapsulation.NONE | ViewEncapsulation.EMULATED | ViewEncapsulation.NATIVE)`
- The default encapsulation strategy is now `ViewEncapsulation.EMULATED` if a component contains styles and `ViewEncapsulation.NONE` if it does not. Before this was always `NONE`.
- `ViewLoader` now returns the template as a string and the styles as a separate array
Call new `(de)hydrateDirectives` methods from `(de)hydrate`. Add a null
implementation in `AbstractChangeDetector` and only override if
necessary for the specific change detector.
Update to #3248
Create `looseNotIdentical => !looseIdentical`, which will save a lot of
unnecessary '!' characters in generated change detectors.
Update to https://github.com/angular/angular/issues/3248
Harp 0.17 does not allow blank lines to appear between filters and their
content. This change ensures that any blank lines that could appear have
been trimmed inside Nunkjucks.
Closes#3325
Reverted from commit 35597a8349
This style change makes the docs look nicer but clang-format doesn't
like it. @mhevery perhaps we can tweak the clang-format rules for this?
Previously, `uninitialized()` was a method, requiring a call as well as
two extra characters everywhere it was used.
Make this value a variable, saving the characters and avoiding the
method call to get its value.
This change also removes the export of `uninitialized` from
change_detect.ts, which is technically a breaking change, however
`uninitialized` is an implementation detail and nobody should be using
it in app logic. By convention, apps should not be importing from files
under `src/`.
Update to #3248.
We discussed last week that our build has been steadily getting longer.
We should track the time so we can easily notice that it went up and
find the culprit.
This hooks us up to https://buildtimetrend.herokuapp.com/ which seems
capable and very quick to setup. We can easily gather the data and
then evaluate the dashboard.
Note that we want to have two different webhooks, and only notify gitter
on transitions, but we want to have timing for all builds, since a
series of passing builds might have a big jump in build time in the middle.
I don't see how to do this with travis.yml so I've overnotified gitter.
Fixes#3001
BREAKING CHANGE:
View renderer used to take normalized CSS class names (ex. fooBar for foo-bar).
With this change a rendered implementation gets a calss name as specified in a
template, without any transformations / normalization. This change only affects
custom view renderers that should be updated accordingly.
Closes#3264
Create `NameRegistry`, responsible for understanding how names are
generated for change detector fields and variables.
Use `NameRegistry` for both JS Jit & Dart pre-generated detectors.
Making progress on #3248
Previously, the compiler would detect cycles where there were none just because of other components that were compiled in parallel. Furthermore, the way ProtoView merging was triggered could result into early exits resulting in errors when trying to instantiate ProtoViews.
Fixes#3206Closes#3211
BREAKING CHANGE
Previously it was possible to pass a custom error reporter to bootstrap, which was used only during the construction of Injector. This had limited utility, so this capability has been removed.
In 2e4a2a0e5a we removed the `@public` tags but the `addJadeDataDocsProcessor`
was still relying upon them being there to identify whether a doc should
be included in the public docs.
Instead we should just check for the doc not being marked with the
`@private` tag.
Closes#3212
BREAKING CHANGES:
Dart applications and TypeScript applications meant to transpile to Dart must now
import `package:angular2/bootstrap.dart` instead of `package:angular2/angular2.dart`
in their bootstrap code. `package:angular2/angular2.dart` no longer export the
bootstrap function. The transformer rewrites imports of `bootstrap.dart` and calls
to `bootstrap` to `bootstrap_static.dart` and `bootstrapStatic` respectively.
When a `Directive` implements a lifecycle interface (e.g. `OnChange` or
`OnInit`), populate its `lifecycle` property if not already populated).
Closes#3181
Static binary component tree of depth 10, i.e. 1024 components.
Current numbers for `pureScriptTime` are:
JavaScript:
Baseline: 27.10+-9%
Ng2: 26.84+-8%
Ng1: 55.30+-14%
Dart:
Baseline: 30.13+-4%
Ng2: 45.94+-3%
Ng1: 128.88+-10%
I.e. in JS we are same speed as baseline right now!
Some background: We had a recent change in the compiler that merges components into their parents already during compilation (#2529). This made Ng2 2x faster in this benchmark (before the Ng2 JS time was 49.59+-14%ms).
Closes#3196
Don't precompile Dart2JS for pull requests, instead serve the dart
sources with pub serve. We were already testing with Dartium so
all we lose is some test coverage of defects exposed only by the
Dart2JS transpiler.
This still runs the dart transformer.
Fixes#3030
BREAKING CHANGE
The @Parent annotation has been removed. Use @Ancestor instead.
@Parent was used to enforce a particular DOM structure (e.g., a pane component is a direct child of the tabs component).
DI is not the right mechanism to do it. We should enforce it using schema instead.
The Angular 2 render compiler can get out of sync between its transformer
execution and its runtime execution, leading to incorrect change detectors with
out-of-order property values. Stable sorting solves this problem (temporarily).
Angular fetches template HTML files outside of the browser's normal parsing flow. As a result, URLs in template files are interpreted relative to the root application, when the components defined by the template files are inserted into the DOM. This change enables a template author to prefix URLs with the string $baseUrl, which will be replaced with the relative base path of the template file.
So for an example template loaded from /component/foo/template.html:
<img src="$baseUrl/logo.png" />
becomes:
<img src="/component/foo/logo.png" />
Addresses #2384.
Due to #3019 we have to check whether a property exists on a DOM element
not before runtime of the application.
Previously, we did this check in JavaScript, making all property values
go through dart js interop. However, this is slow for complex objects.
This commit changes this behavior to first check whether the property exists
before sending the property value to the DOM element via js interop.
Closes#3149
Previously, calls to getBaseHref used document.baseURI, which defaults
to the current path in the absence of a base element in the document.
This leads to surprising behavior.
With this change, getBaseHref returns null when a base element is not
present in the document.
Implement deferred libraries to work with dependency injection and other
angular codegen. This is done by not initializing the library in the parent
ng_deps file when it is declared as deferred, rewriting the import and,
chaining a future that initializes the library in any files that are using
deferred libraries which need angular codegen.
BREAKING CHANGES:
`ViewManager.createView` / `ViewContainerRef.create` have been split into 2 methods:
- `createHostView` which takes dynamically created bindings
- `createEmbeddedView` which takes the newly introduced `TemplateRef`
The new type `TemplateRef` is the combination of a `ProtoViewRef` and and `ElementRef`
from the same place. Use `TemplateRef` when working with embedded views in
`ng-if`, `ng-for`, ... instead of `ProtoViewRef`.
Also, `ProtoViewRef` is no more injectable, but `TemplateRef` is.
First part of #1989 to clean up manual content projection.
Closes#3114
Fix sort order for reflective imports in reflection_remover/rewriter.dart.
Currently there is only one import so the sort order happens to be correct,
but if another one is added the rewrite code will break.
Remove reflector parameter from initReflector method to simplify ng_deps for reflection
initialization. It wasn't used and was added for testability, but wasn't used. This
keeps the interface simplier.
In Dart, '$' indicates the beginning of an interpolation.
- Escapes '$' in strings when generating change detector classes.
- Adds a unit test to cover this case.
The pub publish process was not following through with publishing
packages because the -f flag was not be provided to pub publish,
causing the process to prompt for confirmation before publishing,
which was causing the pub_publish.sh script to skip publishing.
Closes#3077
Closes#2529
BREAKING CHANGES:
- shadow dom emulation no longer
supports the `<content>` tag. Use the new `<ng-content>` instead
(works with all shadow dom strategies).
- removed `DomRenderer.setViewRootNodes` and `AppViewManager.getComponentView`
-> use `DomRenderer.getNativeElementSync(elementRef)` and change shadow dom directly
- the `Renderer` interface has changed:
* `createView` now also has to support sub views
* the notion of a container has been removed. Instead, the renderer has
to implement methods to attach views next to elements or other views.
* a RenderView now contains multiple RenderFragments. Fragments
are used to move DOM nodes around.
Internal changes / design changes:
- Introduce notion of view fragments on render side
- DomProtoViews and DomViews on render side are merged,
AppProtoViews are not merged, AppViews are partially merged
(they share arrays with the other merged AppViews but we keep
individual AppView instances for now).
- DomProtoViews always have a `<template>` element as root
* needed for storing subviews
* we have less chunks of DOM to clone now
- remove fake ElementBinder / Bound element for root text bindings
and model them explicitly. This removes a lot of special cases we had!
- AppView shares data with nested component views
- some methods in AppViewManager (create, hydrate, dehydrate) are iterative now
* now possible as we have all child AppViews / ElementRefs already in an array!
By binding the token `DOM_REFLECT_PROPERTIES_AS_ATTRIBUTES` provided by
the dom_renderer module to `true` in the root injector (i.e. bootstrap()),
all elements whose properties are set by angular will be reflected as
attributes with the prefix "ng-reflect-".
Fixes#2910
Relying on ASI (automatic semicolon insertion)
is allowed in TypeScript because JavaScript allows
it. However, when we run clang-format it doesn’t
understand that these statements are terminated
with a newline and changes the indentation, in bad
cases even breaking the code.
Fixes#817
When we are creating a type definition file for a class has a private constructor,
we convert it to a combination of an instance of a concrete type with no constructor and an interface that contains the other methods.
When this happens, we must also convert the class's heritage from
`implements` to `extends` since interfaces cannot implement other interfaces
or classes.
Fixes a problem with #2996Closes#3002
This fixes several minor indentation issues (instanceof precendence,
type declaration specificity, template string length calculation).
This should also fix some flip-flop situations with template strings.
This means that we can now run just the d.ts file generation by running:
```bash
gulp docs/typings
```
In addition the type definition generation was messing with the other docs tasks
so separating it also fixes problems there.
BREAKING CHANGE:
This change renames all instances of PipeRegistry to Pipes.
As part of this change, the former "defaultPipes" export is
now a Pipes instance, instead of a map. The map that was previously
called "defaultPipes" no longer exists, but may be accessed via
defaultPipes.config.
This is its own commit so that tools have an easier time of preserving
history of the file, by keeping the diff between pipes.ts and
pipe_registry.ts minimal.
Also moved pipe_registry_spec.ts
second attempt after rollback of https://github.com/angular/angular/pull/2946
After each successful build in the dart stable variant, this uploads just enough of the dart
artifacts to mirror what we would push to pub.
By uploading the files instead of a zip, this lets dart users depend on an unreleased snapshot
of angular2, and lets us easily fetch the dart artifacts for sync into google3
without having to re-build (potentially in a subtly different environment).
This doesn't upload anything for pull requests.
Travis is currently stalling, presumably it takes too long to upload this many files.
Also it picks up the dart directory when deploying js, which looks like a bug
with multiple gcs providers, so just do dart for now.
This copies the dist/ folder for each successful travis run
to a google cloud storage bucket, under the SHA of the commit.
We only upload for submitted changes, not PRs.
We can use this to fetch the dart sources for each SHA
without having to re-build them, which is hard to reproduce
since the environment might differ (eg. different Dart SDK)
This change prevents the doc generation from crashing due to a missing module,
but perhaps we need to think of a way of being able to generate the angular.d.ts
file correctly in `gulp public_docs`, perhaps by removing the need for
angular2/angular2.api
The properties of the annotation classes are not really the public API.
Users will interact with these via a decorator, and the decorator
takes a single arg, typed with the args class. Thus the comment is
more useful on the arg class.
This also fixes the problem of intellisense/autocomplete not showing
the important docs as you fill in the properties in a decorator
declaration.
We had the same symbol exported as the interface
for Component decorator as well as the class for
Component annotation, and dgeni only showed the
latter.
Rename the interfaces for decorators with an ‘I’
prefix so they are retained in the .d.ts output.
Previously, when a return type was missing it
could have been any. But following #2746 we
require return types so remaining untyped returns
must be void.
this is no longer necessary and if anyone runs two gulp processes in parallel can actually cause
issues because once one of the processes ends, it delets the tmp dir which can affect the remaining
process
In non-transformed mode the funcOrValue check was enough, but once
transformed these all use the same function for getters, so we need
to also check the name.
BREAKING CHANGE:
The Http module previously would return RxJS Observables from method calls
of the Http class. In order to support Dart, the module was refactored to
return the EventEmitter abstraction instead, which does not contain the same
combinators or subscription semantics as an RxJS Observable. However, the
EventEmitter provides a toRx() method which will return an RxJS Subject,
providing the same subscription and combinator conveniences as were
available prior to this refactor.
This is temporary, until issue #2794 is resolved, when Observables will
again be returned directly from Http class methods.
Travis creates an empty node_modules directory when the cache is empty which confuses
our current script into thinking that it's ok to require fs-extra. While this is rare,
it's better not to depend on anything in node_modules when purging it, so I reimplemented
recorsive delete that we use to purse node_modules.
This is an alternative to #2778. All of the symlinks to packages directory within the test directory
are not needed for running tests, so we can safely remove them. This removes 80k files from the test directory
which significantly speeds up Karma.
Closes#2437
The BaseRequestOptions class is responsible for declaring default values,
while the RequestOptions class is merely responsible for setting values
based on values provided in the constructor.
BREAKING CHANGE: HttpFactory is no longer available.
This factory provided a function alternative to the `request` method of the
Http class, but added no real value. The additional factory required an
additional IHttp interface, an odd way to inject while preserving type information
(`@Inject(HttpFactory) http:IHttp`), and required additional documentation in the
http module.
Closes#2564
This change causes the build system to write a log file into the tmp folder after each build.
This file contains command line arguments that tell karma about all the added/changed/removed files
from the last build. Karma can then use this list instead of doing internal globbing which can be
very expensive especially for hte dart builds that contain thousands of files.
Closes#2437
The .nvmrc file is used by nvm if you don't specify a version. This lets us type Found '/Users/alexeagle/Projects/angular/.nvmrc' with version <0.12>
Now using node v0.12.2. It doesn't check that you are using the node version from the file, however, so this won't prevent version skew.
See https://github.com/creationix/nvm#usagecloses#1995
One of the non-angular broccoli plugins returns a weird object. We can't
assume that all trees meet the contract that we expect them to meet, so
we do a typecheck before storing the result of the rebuild.
Closes#2662
Don’t need to bundle them as they are already
present in G3. I.e. the benchpress bundle
only includes benchpress and Angular2 bits.
Also removes adding license headers for now,
as we only have one license.
This makes sure just running clang-format will use whatever version is
used in the project, by loading it from the closest node_modules folder.
It also moves the clang-format dependency to the top and explicitly
passes it to gulp-clang-format, giving us more control over the version
used.
Move the section from `CONTRIBUTING.md` (which should only be policy) to
`DEVELOPER.md` (which should document developer tooling).
Consolidates the whole thing a bit, and adjusts for the now always
installed `git clang-format` hook. Also mentions clang-format's lookup
behaviour.
This removes some, but not all, of the manual work needed to patch up our
.d.ts for pushing to DefinitelyTyped. Remaining manual steps are:
- some types still missing
- declaration of decorators
- remove destructuring args
See #2686.
add test in gulpfile which will compile a basic TS file with generated
angular2.d.ts to ensure generated d.ts is valid syntactic TS
Adds support for enums in .d.ts generation pipeline.
Removes renaming reexports in http module.
BREAKING CHANGES:
- rename `ElementRef.domElement` to `ElementRef.nativeElement`
- add `Renderer.getNativeElementSync` to make the app side
less dependent on the dom renderer.
- don’t use `ElementRef.nativeElement` in directives but
use the methods on `Renderer` directly.
- Removed `ElementRef.setAttribute`. Use `Renderer.setElementAttribute` instead.
Closes#2712
Last part of #2476Closes#2476
BREAKING CHANGES:
- Almost all methods in `Renderer` now take a `RenderElementRef` instead
of a `ViewRef` + `boundElementIndex`.
- These methods can be called with the `ElementRef` from the app side
directly.
Closes#2706

In order to speedup the startup time of test.unit.js task, we are moving the circular dependency check into
a pre-test check that executes only on travis. Similarly we are moving the style check to a post-test check
that executes on travis.
This way if a circular dependency issue occurs, we find it before running tests on CI and if the code
is not formatted we fail the build only if all the tests pass.

BREAKING CHANGES:
- host actions don't take an expression as value any more but only a method name,

- Renderer.setElementProperty does not take `style.`/... prefixes any more.
Use the new methods `Renderer.setElementAttribute`, ... instead
Part of #2476Closes#2637
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
You can now run `gulp serve.e2e.prod` to instantiate a task that watches

Allows to add or remove previous siblings of text
interpolations (e.g. by added `<script>` tags for
content reproduction, or by removed `<style>` tags).
Also calculates correctly whether an element is
empty.
Fixes#2591
As the constructed objects have an any type, the
resulting containers are assignable to any type:
var x: Map<string, number> = new Map();
That is useful to avoid having to specify types
twice when declaration and assignment are in
different places.
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.
StringMap really ought to always enforce a string
key, and also ought to have an index property.
This currently breaks too much code in Angular, so
should be fixed in a follow up Pull Request
separate from this.
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.
Previously, class members were ordered alphabetically.
This change leaves it up to the class author to
determine the order in which they would like
properties and methods to appear in class
documentation, without having to create methods like
`zUnimportantMethod`.
Fixes#2569
Benchpress now prints out the best and worst frame time in addition to the percentage of frames that hit the target of 60fps.
It also renames 'meanFrameTime' to 'frameTime.mean'. That way, all frameTime metrics start with a common suffix and will be grouped together in the console reporter.

Uglify files related to angular2.min.js bundle in one task.
Include reflect.js in the bundle, which was previously missing. Minify reflect.js, zone.js, and angular2.min.js using uglify.
Move all remaining unit tests for change detectors to exercise Dart
pre-generated change detectors as well as `dynamic` and `JIT` change
detectors.
See #502
More the change detect tests that exercise various detection modes to
use the Dart pre-generated change detectors in addition to the `dynamic`

Once we add support for addedPaths then this implementation will be significantly faster than the original.
In the meantime we benefit from having stable output directory which solves issues with certain files disappearing

System.js seems detect an empty file as global and choke on exporting
symbols from angular2/angular2 (possibly a bug in system.js).
As temporary measure we make sure that the file has some (fake) runtime

- 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.
Note that this also removes the `components` option from `RouteConfig`.
This functionality will be reintroduced with the more general `//` routing.
See #2329 for more details.
Update the transformer's `TemplateCompiler` phase to avoid setting
`reflector.reflectionCapabilities`, allowing asynchronous
operations, and restoring the original value, which allows
`reflector.reflectionCapabilities` to get into a bad state.
This requires some hacks, documented in
https://docs.google.com/document/d/1nNebWTiLzz5ePcit_bjZPtaiSIFU4EsQKUlX7LX0c0A/edit
Changes:
- include subtyping info in angular2.d.ts by adding 'extends supertype'
- export missing symbols needed transitively by angular2/angular2
- because of decorator/annotation mismatch, we can't export these to applications.
So I've added a separate angular2.api.ts file to re-export specifically to .d.ts
generation.
- Hack to remove aliases introduced by 'import * as alias' syntax
- Hack to deal with Error still an interface
note that we require users to install the transitive dependencies - this is how TSD works.
It is very noisy, especially when multiple trees are used. Since the
tree differ is fairly quick, it's not measuring the real costs of a
plugin anyhow.
Closes#2378
Add a type for the `context` field in Dart's pre-generated change
detectors. This requires slight changes to set the dehydrated value of
`context` to `null` rather than `ChangeDetectionUtil.uninitialized()`,
which was its former dehydrated state.
Mirror these chagnes as closely as possible in the
`ChangeDetectionJITGenerator` to allow easier maintenance.
Closes#2070
To support interface-based lifecycle methods (#2220), we need to be able
to query for the `interface`s a class supports. Record implemented

Replaces the multiple arrays of `DomView`
by a single array with `DomElement`s.
Note: this commit does not show a performance regression
(tested against the tree benchmark locally).
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.
Free embedded views are view instances that are created
logically in the same was as views of a ViewContainer,
but their dom nodes are not attached.
BREAKING CHANGE:
- `Renderer.detachFreeHostView` was renamed to
`Renderer.detachFreeView`
- `DomRenderer.getHostElement()` was generalized into
`DomRenderer.getRootNodes()`
Largetable benchmark with `interpolationAttr` and 200 rows / 20 columns:
Time for destroy/create pair dropped from about 1260ms to about 150ms.
Related to #2298, but does not really fix it as we are still slow
if people are using `<content>`.
Closes#2297
It was confusing because the test.unit.dart task does ignore the initial, and
the logger was hardcoded to always ignore the first task, leading to the appearance
that a run was happening twice for no reason.
Also, fixed the "fake ignoreInitial" handling to not rely on a fake event, which
is not necessary.
Closes#2101
The semantics between ES6 `Promise#all` and Dart's `Future#wait` are
different for values that are not `Promise`/`Future`s. In ES6,
non-`Promise` values are immediately completed to their current value.
In Dart, non-`Future` values cause an error.
Updated Dart's `PromiseWrapper#all` implementation to conform to the ES6
spec.
Use the `ProtoViewDto` created by the render `Compiler` to create a
`ChangeDetectorDefinition`.
From there, generate a subclass of `AbstractChangeDetector` for each
`ChangeDetectorDefinition`.
Run some basic unit tests for the dynamic and JIT change detectors on
pre-generated change detectors.
Usage: bootstrap the app with the special binding
`ELEMENT_PROBE_CONFIG` from `angular2/debug`.
This will provide a global method `ngProbe(element)` that
will expose a `DebugElement` with directive instances, ... on it.
During tests that use Angular's test injector, the probe is
enabled by default. The `DebugElement ` can be retrieved via the
function `inspectDomElement` of `angular2/debug`. Note
that the `TestComponentBuilder` already returns `DebugElement `s.
Closes#1992
When a template contains bound text nodes as root nodes,
we used to store the document fragment that we got from
cloning `template.content`. However, this fragment will be
empty as soon as the view gets attached. Now we store
`null` instead of the document fragment in this case.
Also groups the 3 cases in `_createView` so they are easier to
understand.
Previously we assumed that all input and ouput paths for broccoli trees are immutable, that turned out to be
incorrect.
By adding a tree stabilizer plugin in front of each diffing plugin, we ensure that the input trees
are stable. The stabilization is done via symlinks which is super cheap on platforms that support
symlinks. On Windows we currently copy the whole input directory, which is far from ideal. We should
investagate if using move operation on Windows is ok in the future to improve performance.

But do it during the build process for cjs.
Right now we only need this when we transpile from ts

the rest.
Previously this was a bit cryptic as we just had a `hideSpecialExports` flag.
Now it ignores exports that match an array of regexes, with the default case
being those exports called `___esModule`.
ts2dart's node-source-map-support dependency was updated to match the main
line patch, but this changed the SHA in the existing repo, breaking Angular's
shrink wrapped dependency.
This update changes the dependency back to an existing SHA.
Previously, tree-differ would not correctly handle symlinks to deleted files, resulting in
an ENOENT errno being tossed by libuv.
This change fixes this to ensure that symlinks are safely handled, performantly.
Closes#1961
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.
It is possible for a class defined first to be referencing a class defined later,
and as a result at the time of the definition it is not possible to access the later's
class reference. This allows to refer to the later defined class through
a closure.Closes #1891
BREAKING CHANGE:
`AppViewManager.createInPlaceHostView` is replaced by
`AppViewManager.createRootHostView` (for bootstrap) and
`AppViewManager.createFreeHostView` (for imperative components).
The later creates new host elements that are not attached anywhere.
To attach them, use `DomRenderer.getHostElement(hostviewRef)`
to get the host element.
Closes#1920
if any tasks executed by gulp results in an error, gulp will try hard to show errors. these are usually irelevant in the
watch mode. this is why it's ok to supress them except when running in the ci test mode, in which case failing tasks and logging
exceptions is helpful.
Closes#1881
Also consolidates metadata handling in `ElementInjector`
BREAKING CHANGE:
- renames `DirectiveMetadataReader` into `DirectiveResolver`
and removes `src/core/compiler/directive_metadata`.
Fixes#1712Fixes#1713
We ran across fatal issues with npm shrinkwrap on node 0.10.x which don't go away even with npm 2.9.x.
Upgrading node to 0.12 fixed the shrinkwrap issues. Since now we run node 0.12 on ci as well, there
is no reason for anyone to use node 0.10 during development.
BREAKING CHANGE:
VmTurnZone has been renamed to NgZone.
- The public API has not chnanged,
- The "outer" zone is now named "mount" zone (private to NgZone).
Before this PR there were only 2 zones: root zone = outer zone > inner
zone.
This PR creates the outer zone as a fork of the root zone: root > outer
> inner.
By doing this it is possible to detected microtasks scheduling in the
outer zone and run the change detection less often (no more than one
time per VM turn).
The PR also introduce a Promise monkey patch for the JS implementation.
It makes Promises aware of microtasks and again allow running the change
detection only once per turn.
BREAKING CHANGE:
A collection of all the form directives is exported
under `formDirectives`
while those were previously available
under `FormDirectives`.
Closes#1804
The async pipe in templates will now delegate to both Observable pipe or Promise pipe,
whichever first says it can support the input. Therefore, it's beneficial to disambiguate
the name of the AsyncPipe/AsyncPipeFactory constructors to reflect that these actually
support only Observables.
Update the `TemplateCompile` step to use the full render `Compiler`.
Provide `DirectiveMetadata` for `ViewDefinition` objects and use it to
run the `DirectiveParser` step of the render compile pipeline.
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
gulp-watch uses chokidar which uses fsevents which is much better than fs polling or relying on fs.watch.
fsevents use only one FD per watch invocation as opposed to one FD per watched directory and any subdirectory.
this should improve the situation with EMFILE errors (caused by lack of available file descriptors)
----
I also tried the following:
gulp-sane: requires watchman installation via brew so I didn't want to request that everyone goes throught that yet
gulp-chokidar: didn't work, seems to be obsolete
Special regexp tokens were allowed unchanged previously, which incorrectly broke
the include/exclude behaviour. Now, they're escaped first.
Closes#1721Closes#1752
By default, gulp-typescript currently depends on typescript 1.4, which doesn't work for us.
For example, it doesn't allow `let` when emitting ES5, along with lots of other errors.
It so happens that npm sometimes makes this work, as seen by the warning
```npm WARN unmet dependency /Users/alexeagle/Projects/angular/node_modules/gulp-typescript requires typescript@'1.4.1' but will load
npm WARN unmet dependency /Users/alexeagle/Projects/angular/node_modules/typescript,
npm WARN unmet dependency which is version 1.5.0```
but when we update our node_modules in a certain way, we lose this setup and it breaks.
We should be explicit about using a different version of typescript than gulp-typescript depends on.
Update `TemplateCompiler` transform step to use abstractions used by the
render `Compiler`. For example, template code is now loaded via an
instance of `TemplateLoader` and external resources are fetched via an
instance of `XHR`.
previously there was a chance of race conditions that could sporadically fail the build.
additionally runing a task via gulp.start or runSequence always reruns its dependencies, which meant that we were blowing away
the build.tools build and rebuilding everything from scratch even during the interactive/watch mode. This meant that the build
pipeline cache was destroyed on every change and we never got the benefit of incremental compilation
tree-differ:
- export both TreeDiffer and DiffResult interface
diffing-broccoli-plugin:
- factory class for wrapping DiffingBroccoliPlugins and turning them into BroccoliTrees
broccoli-dest-copy:
- refactor into DiffingBroccoliPlugin
broccoli-traceur:
- refactor into DiffingBroccoliPlugin
Previously, karma used a custom preprocessor. Instead, have karma
run built dart from the `dist` folder and use gulp and broccoli
to watch for changes.
Using string1 === string2 translates to identical(string1, string2) in
dart, which is incorrect as it is possilbe for dart strings to have
different reference.
Add a step that reads `DirectiveMetadata` object off annotated classes
into `.ng_meta.dart` files. These will be used by the `TemplateCompiler`
step as inputs to the Angular 2 render compiler.
Update one test to avoid unsupported functionality, format others.
Due to limitation of system build, the router cannot have its own sfx
bundle.
Fixes an issue with RouteConfig decorator by moving it into its own
file.
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.
This removes .es6 files which are pure duplicates of a
.ts file in the same folder.
Next we need to remove .js files as well, and remove karma preprocessors for dart.
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
Add utility methods to convert `render.dom.DirectiveMetadata` to and
from maps. This will allow saving and restoring `DirectiveMetadata` in
the Angular 2 Transformer.
We discussed adding this as a member on `DirectiveMetadata`. Since this
is not necessary for anything except the Transformer, we decided to put
it into a separate file to avoid shipping it with the Angular 2 core
code.
This is a prerequisite for switching to TypeScript. We need to remove the Traceur preprocessor
from Karma, so we have the build specified in a single place (broccoli tree def'n).
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`.

You can generate docs for comsumption by the angular.io website by running:
```bash
gulp docs/angular.io
```
The generated docs can be found in `dist/angular.io`
on our CI server we currently split each build into the building phase and testing phase, this change aligns test.unit.tools/ci
with the rest of ci test taskswq
components:
- gulp test.unit.broccoli task
- mock-fs for mocking our FS in unit tests
- jasmine d.ts file for type checking
jasmine lib is provided by minijasmine2 so we don't need to include it explicitly
This change solves several problems:
- the broccoli pipeline is used to compile the node/cjs tree upon any change to the modules/ directory
- jasmine tests run in a new process removing the need to clean up environment after each test
- since we transpile only those test files that are actually needed for node/cjs build, we transpile less and don't need to filter out tests
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
We have Dart code in `angular2` module that ought to be in its own
package. Examples include Dart analysis plugins, and potentially the
transformers (although transformers cannot be moved out just yet).
However, this code is Dart-only and it doesn’t make sense to use JS
directory layout for it. This commit introduces a sub-directory called
`modules_dart`. All modules in this directory are pure Dart packages
using standard pub directory layout. The code in these packages never
gets transpiled. It is directly copied to `dist` unmodified, except an
adjustment in relative paths in `pubspec.yaml` files.
When the mean is 0, the coefficient of variation is calculated to be
NaN, which is not meaningful, so instead of printing "+-NaN%", just
don't print the CV at all.
Closes#908Closes#1444
I didn't get a full trace back for my evidence I got from making this example work. EventEmitter was instantiated and assigned to wrong property. Also the mapping should be done using the component property name as it will be obtained via accessor and exposed on the directive (as far as I understood).
Previously, getting testability was `window.angular2.getTestability`
This was because the plan was to export the API to the window as
angular2. However, the decision was changed to make this just `angular`
in 3177576ad6
To decouple testability from the rest of the Angular API, just make it
one function, `window.getAngularTestability`.
Add two transform parameters to aid in debugging the transformer
- `mirror_mode`, with values {`debug`, `none`, and `verbose`}
- `init_reflector`, with values {`true`, `false`}
`mirror_mode`:
- `debug`: Allow reflective access, but log a message if it is used
- `none`: Remove reflective access, `throw` if it is used. Default value
- `verbose`: Allow reflective access, log a stack trace if it is used
`init_reflector`: Whether to generate calls to our generated
`initReflector` code.
These will be useful to reveal areas where the transformer is not generating
appropriate code and to quickly see where reflective accesses occur.
When the pub mode is `transform_dynamic`, we run in MirrorMode.debug
with `init_reflector = false`. This is used for testing purposes.
Previously, light dom nodes that were not used by any content tag
were not removed from a view on redistribute. This lead
to a bug when reusing a view from the view pool, as it
still contained stale reprojected nodes.
Fixes#1416
You can now write a link to a member of a class by appending the member name
to the class name joined by a hash sign:
```
{@link ControlGroupDirective#addDirective `addDirective`}
```
By default the link will contain the text of the class rather than the member
so you must add it as an inline code text snippet in the link tag.
Closes#1432
index_static.js & index_static.html are unnecessary in Js and are now
essentially generated via the Dart transformer. The angular
transformer is specified in examples/pubspec.yaml; use pub build to
create a transformed application that does not use dart:mirrors.
Create index_dynamic.js & index_dynamic.html, which are used to test
that the app runs equally well with mirrors and without.
Closes#495
This commit enables links to other docs, such as classes and modules,
via the `{@link CodeIdentifier}` style inline tag.
Dgeni identifies what you are linking to by comparing the identifier to the
aliases for each doc. If no alias matches the identifier then the dgeni
run exits with a missing doc in link error. If more than one alias matches
the identifier then dgeni exits with an ambiguous link error.
In the future we could build in some heuristics for choosing a preferred
doc when the link is ambiguous, such as choosing a public doc over a
non-public doc; and choosing a code component that is in the same module as
the doc where the link is found.
Currently there are two aliases for each API component: its name and its
identier. For example, if the `Directive` class is exported from
`angular2/annotations`, so its aliases are 'Directive' and
`angular2/annotations.Directive`.
There is an issue in the non-public doc generation, which means that it
does not yet have `{@link}` tags implemented. This is that when we re-export
a code component, it gets cloned into another module. This means that a
simple reference to the code component's name will always produce an
ambiguous link. This can be fixed with a heuristic as described above.
Meanwhile you can avoid this by always using the full id of the code
component if it is being re-exported.

Since we are currently stuck on node 0.10 (see #1396), this will at least help us avoid
some of the npm bugs present in older version that comes with 0.10.
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.
Create a method that recursively walks imports from an entry point and
determines where classes are registered.
Use this information to determine if a particular annotation implements or
extends Injectable or Template.
Since `DynamicChangeDetection` and `JitChangeDetection` classes are alreadt in the
public module, they do not need to be annotated with a `@exportAs` tag
Closes#1353
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.
If an "empty" file (like angular2/template.js) is imported
it is auto-detected as the one using "global" format by the
system builder. This is incorrect as the entire angular2 build
output is in the ES6 format.
Removing empty import till it has some content.
Closes#1329
Our style guide includes formatting conventions. Instead of wasting time in reviewing PRs discussing things like indenting, and to avoid later deltas to fix bad formatting in earlier commits, we want to enforce these in the build.
The intent in this change is to fail the build as quickly as possible in travis, so those sending a PR immediately know they should run clang-format and update their commit. When running locally, we want users to know about formatting, but they may not want to act on it immediately, until they are done working. For this reason, it is only a warning outside of the continuous build.
This is done by having a check-format task which should run on most local builds, and an enforce-format task only run by travis.
chore(doc-gen): capture docs for modules from comments
Closes#1258
docs(*): add module description jsdoc tags
docs(*): add @public tag to public modules
chore(doc-gen): fix overview-dump template
The template was referencing an invalid property
chore(doc-gen): use `@exportedAs` and `@public` rather than `@publicModule`
This commit refactors how we describe components that are re-exported in another
module. For example the "public" modules like `angular/angular` and `angular/annotations`
are public but they only re-export components from "private" modules.
Previously, you must apply the `@publicModule` tag to a component that was to be
re-exported. Applying this tag caused the destination module to become public.
Now, you specify that a module is public by applying the `@public` tag and then
you can "re-export" components to other modules by applying the `@exportedAs`
giving the name of the module from which the component will be re-exported.
tag. This tag can be used multiple times on a single component, allowing the
component to be exported on multiple modules.
docs(*): rename `@publicModule` to `@exportedAs`
The `@publicModule` dgeni tag has been replaced by the `@exportedAs`
dgeni tag on components that are to be re-exported on another module.
Closes#1290
- Allow the user to specify multiple entry points to an app.
- Allow the Angular 2 transformer to run without explicit entry points to

Closes#1246
This commit adds a plugin for the event manager, to allow a key name to
be appended to the event name (for keyup and keydown events), so that
the callback is only called for that key.
Here are some examples:
(keydown.shift.enter)
(keyup.space)
(keydown.control.shift.a)
(keyup.f1)
Key names mostly follow the DOM Level 3 event key values:
http://www.w3.org/TR/DOM-Level-3-Events-key/#key-value-tables
There are some limitations to be worked on (cf details
in https://github.com/angular/angular/pull/1136) but for now, this
implementation is reliable for the following keys (by "reliable" I mean
compatible with Chrome and Firefox and not depending on the keyboard
layout):
- alt, control, shift, meta (those keys can be combined with other keys)
- tab, enter, backspace, pause, scrolllock, capslock, numlock
- insert, delete, home, end, pageup, pagedown
- arrowup, arrowdown, arrowleft, arrowright
- latin letters (a-z), function keys (f1-f12)
- numbers on the numeric keypad (but those keys are not correctly simulated
by Chromedriver)
There is a sample to play with in examples/src/key_events/.

Queries allow a directive to inject a live list of directives of a given
type from its LightDom. The injected list is Iterable (in JS and Dart).
It will be Observable when Observables are support in JS, for now it
maintains a simple list of onChange callbacks API.
To support queries, element injectors now maintain a list of
child injectors in the correct DOM order (dynamically updated by
viewports).
For performance reasons we allow only 3 active queries in an injector
subtree. The feature adds no overhead to the application when not
used. Queries walk the injector tree only during dynamic view
addition/removal as triggered by viewport directives.
Syncs changes between viewContainer on the render and logic sides.
Closes#792
This switches all transpilation over from using Traceur to using ts2dart, based
on the TypeScript tool chain. Transpilation is a bit slow due to issues with
the gulp integration, but that should be easily fixable once we move to
broccoli.

extracts ProtoView.instantiate and replaces ViewPool.
Note: This is a work in progress commit to unblock other commits.

Needed to change Renderer.mergeChildComponentProtoViews to not create
new ProtoViews to be able to deal with cyclic references.
This commit is part of using the new render layer in Angular.
- 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.
Adds a gulp task which builds the .ts files (in the cjs build only).
The new files have extension .ts since they are now valid typescript.
Unfortunately until Typescript can emit System.require, we have to keep the old .es6 version
so traceur works inside the Karma preprocessor. This should be fixed soon.
Add a transformer for `di` which generates `.ng_deps.dart` files for all
`.dart` files it is run on. These `.ng_deps.dart` files register
metadata for any `@Injectable` classes.
Fix unit tests for changes introduced by the di transformer.
When using `pub (build|serve) --mode=ngstatic`, we will also generate
getters and setters, parse templates, and remove import of `dart:mirrors`
in the Angular transform. Because this is still relatively immature, we
use the mode to keep it opt-in for now.
Closes#700
We do this as we are seeing flakes in Chrome with ECONNREFUSED.
Also reuses the same browser window.

Closes#1137
This uses tsd to fetch the typings from another git repo. I've forked the DefinitelyTyped repo because some typings we use are not available upstream.
We should probably fork it in the Angular org, so everyone on the team has commit access to our DefinitelyTyped fork.
When a `Template` annotation declares a `url` value, parse it to
generate `getter`s, `setter`s, and `method`s which will it needs to
access reflectively.
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.
This only transpiles one package to start with: di/
It ensures that package transpiles without errors, so no one can
introduce non-TypeScript syntax.
Next step is to widen the task inputs to cover additional packages.
See design doc for the migration:
https://docs.google.com/document/d/14RJLhu6uuv7NchFkAb6PKzOOO0L7l3Z507eKWzkEUhQ/edit
A convenience task 'ts2dart' is added for developing ts2dart, and
it runs all of the angular code through the transpiler to collect errors.
Now the visitor will find the last jsdoc style comment (e.g. `/** jsdoc comment */`)
before the current code item, ignoring any inline style comments (e.g. `// inline comment`)
in between.
Closes#1072
Based on the discussion in #776 we can't reliably check if a given
element has a particular property at the compilation time. As such
the existing algorithm detecting "missing" directives can't be used.
We need to see if there is a different / better algorithm or maybe
those checks need to be moved later in the process (runtime). Leaving
integration tests in place (disabled) so we can come back to the
topic after unblocking the situation.

## Running Tests Locally
### Basic tests
### Full test suite
1.`$(npm bin)/gulp test.unit.js`: JS tests in a browser; runs in **watch mode** (i.e. karma
watches the test files for changes and re-runs tests when files are updated).
2.`$(npm bin)/gulp test.unit.cjs`: JS tests in NodeJS; runs in **watch mode**
3.`$(npm bin)/gulp test.unit.dart`: Dart tests in Dartium; runs in **watch mode**.
*`npm test`: full test suite for both JS and Dart versions of Angular. These are the same tests
that run on Travis.
If you prefer running tests in "single-run" mode rather than watch mode use
You can selectively run either the JS or Dart versions as follows:
*`$(npm bin)/gulp test.all.js`
*`$(npm bin)/gulp test.all.dart`
### Unit tests
You can run just the unit tests as follows:
*`$(npm bin)/gulp test.unit.js`: JS tests in a browser; runs in **watch mode** (i.e.
watches the test files for changes and re-runs tests when files are updated).
* `$(npm bin)/gulp test.unit.cjs`: JS tests in NodeJS; runs in **watch mode**.
* `$(npm bin)/gulp test.unit.dart`: Dart tests in Dartium; runs in **watch mode**.
If you prefer running tests in "single-run" mode rather than watch mode use:
*`$(npm bin)/gulp test.unit.js/ci`
*`$(npm bin)/gulp test.unit.cjs/ci`
*`$(npm bin)/gulp test.unit.dart/ci`
**Note**: If you want to only run a single test you can alter the test you wish
to run by changing `it` to `iit` or `describe` to `ddescribe`. This will only
run that individual test and make it much easier to debug. `xit` and `xdescribe`
can also be useful to exclude a test and a group of tests respectively.
The task updates the dist folder with transpiled code whenever a source or test file changes, and
Karma is run against the new output.
**Note** for transpiler tests: The karma preprocessor is setup in a way so that after every test
run the transpiler is reloaded. With that it is possible to make changes to the preprocessor and
run the tests without exiting karma (just touch a test file that you would like to run).
**Note**: If you want to only run a single test you can alter the test you wish to run by changing
`it` to `iit` or `describe` to `ddescribe`. This will only run that individual test and make it

rights to built them in your operating system.
