No longer locks the Material unit tests job to a specific branch, but rather allows

Previously, the ivy-2019 branch of the Material (aka components) repo was

These changes are not longer necessary, as Material's master branch is

development and its support for more recent dependencies, e.g. TypeScript,
it is desirable for us to be on a newer version of Material.
This commit moves the Material tests away from the ivy-2019 branch, to a

as that would introduce a moving target into Angular's CI checks, which
is undesirable.

In ViewEngine nodes that were inserted through `Renderer2` would also be picked up by `DebugNode.query` and `DebugNode.queryAll`. This worked because everything in ViewEngine went through `Renderer2` and `DebugRenderer2` in dev mode which was able to keep track of the child nodes as they're being inserted. This no longer works in Ivy, because we don't use `DebugRenderer2` and debug nodes work a little differently. These changes work around the issue by walking the DOM as the logical tree is being walked and looking for matches. Note that this is __not__ optimal, because we're walking similar trees multiple times. ViewEngine could do it more efficiently, because all the insertions go through Renderer2, however that's not the case in Ivy. This approach is being used because:
1. Matching the ViewEngine behavior would mean potentially introducing a depedency from `Renderer2` to Ivy which could bring Ivy code into ViewEngine.
2. We would have to make `Renderer3` "know" about debug nodes.
3. It allows us to capture nodes that were inserted directly via the DOM.

Currently developers can use the `By` class to construct common

The `directive()` and `all()` predicates are currently returning

is too strict since the predicate is not specific to `DebugElement`
instances and can also apply to `DebugNode` instances.
Meaning that developers are currently able to use the `directive()`
predicate when using `queryAllNodes()`. This is a common practice

`--strictFunctionTypes` flag as the `DebugElement` predicate type

Currently we reuse the same instruction both for regular property bindings and property bindings on the `host`. The only difference between the two is that when it's on the host we shouldn't support inputs. We have an optional parameter called `nativeOnly` which is used to differentiate the two, however since `nativeOnly` is preceeded by another optional parameter (`sanitizer`), we have to generate two extra parameters for each host property bindings every time (e.g. `property('someProp', 'someValue', null, true)`).
These changes add a new instruction called `hostProperty` which avoids the need for the two parameters by removing `nativeOnly` which is always set and it allows us to omit `sanitizer` when it isn't being used.
These changes also remove the `nativeOnly` parameter from the `updateSyntheticHostBinding` instruction, because it's only generated for host elements which means that we can assume that its value will always be `true`.

There are two places in the ngcc processing where it needs to load the
content of a file given by a general path:
* when determining the format of an entry-point.
To do this ngcc uses the value of the relevant property in package.json.
But in the case of `main` it must parse the contents of the entry-point
file to decide whether the format is UMD or CommonJS.
* when parsing the source files for dependencies to determine the order in
which compilation must occur. The relative imports in each file are parsed
and followed recursively, looking for external imports.
Previously, we naively assumed that the path would match the file name exactly.
But actually we must consider the standard module resolution conventions.
E.g. the extension (.js) may be missing, or the path may refer to a directory
containing an index.js file.
This commit fixes both places.
This commit now requires the `DependencyHost` instances to check
the existence of more files than before (at worst all the different possible
post-fixes). This should not create a significant performance reduction for
ngcc. Since the results of the checks will be cached, and similar work is
done inside the TS compiler, so what we lose in doing it here, is saved later
in the processing. The main performance loss would be where there are lots
of files that need to be parsed for dependencies that do not end up being
processed by TS. But compared to the main ngcc processing this dependency
parsing is a small proportion of the work done and so should not impact
much on the overall performance of ngcc.

When profiling ngcc it is notable that a large amount of time
is spent dealing with an exception that is thrown (and handled
internally by fs) when checking the existence of a file.
We check file existence a lot in both finding entry-points
and when TS is compiling code. This commit adds a simple
cached `FileSystem`, which wraps a real `FileSystem` delegate.
This will reduce the number of calls through to `fs.exists()` and
`fs.readFile()` on the delegate.
Initial benchmarks indicate that the cache is miss to hit ratio
for `exists()` is about 2:1, which means that we save about 1/3
of the calls to `fs.existsSync()`.
Note that this implements a "non-expiring" cache, so it is not suitable
for a long lived `FileSystem`, where files may be modified externally.
The cache will be updated if a file is changed or moved via
calls to `FileSystem` methods but it will not be aware of changes
to the files system from outside the `FileSystem` service.
For ngcc we must create a new `FileSystem` service
for each run of `mainNgcc` and ensure that all file operations
(including TS compilation) use the `FileSystem` service.
This ensures that it is very unlikely that a file will change
externally during `mainNgcc` processing.

Adds a schematic and tslint rule that automatically migrate the consumer from `Renderer` to `Renderer2`. Supports:
* Renaming imports.
* Renaming property and method argument types.
* Casting to `Renderer`.
* Mapping all of the methods from the `Renderer` to `Renderer2`.
Note that some of the `Renderer` methods don't map cleanly between renderers. In these cases the migration adds a helper function at the bottom of the file which ensures that we generate valid code with the same return value as before. E.g. here's what the migration for `createText` looks like.
Before:
```
class SomeComponent {
createAndAddText() {
const node = this._renderer.createText(this._element.nativeElement, 'hello');
node.textContent += ' world';

Adds the new `classMapInterpolate1` through `classMapInterpolate8` instructions which handle interpolations inside the `class` attribute and moves the interpolation logic internally. This allows us to remove the `interpolationX` instructions in a follow-up PR.
These changes also add an error if an interpolation is encountered inside a `style` tag (e.g. `style="width: {{value}}"`). Up until now this would actually generate valid instructions, because `styleMap` goes through the same code path as `classMap` which does support interpolation. At runtime, however, `styleMap` would set invalid styles that look like `<div style="0:w;1:i;2:d;3:t;4:h;5::;7:1;">`. In `ViewEngine` interpolations inside `style` weren't supported either, however there we'd output invalid styles like `<div style="unsafe">`, even if the content was trusted.

There's no build time dependency from @angular/core to @angular/compiler,
so core can't directly refer to compiler types. To overcome this limitation,
there's a facade layer defined in the compiler and duplicated in core,
such that during runtime all types will correctly align.
There's a testcase in the compiler that verifies that all such facade types
are compatible across core and compiler, such that the core types can't get
misaligned with the actual definitions in the compiler. This suite of
tests were missing the `R3BaseMetadataFacade` facade type, so it was possible
for this type to get out of sync.

When a class uses Angular decorators such as `@Input`, `@Output` and
friends without an Angular class decorator, they are compiled into a
static `ngBaseDef` field on the class, with the TypeScript declaration
of the class being altered to declare the `ngBaseDef` field to be of type
`ɵɵBaseDef`. This type however requires a generic type parameter that
corresponds with the type of the class, however the compiler did not
provide this type parameter. As a result, compiling a program where such
invalid `ngBaseDef` declarations are present will result in compilation
errors.
This commit fixes the problem by providing the generic type parameter.

Currently in Ivy whenever we encounter a new namespace, we set it in the global state so that all subsequent nodes are created under the same namespace. Next time a template is run the namespace will be reset back to HTML.
This breaks down if the last node that was rendered was under the SVG or MathML namespace and we create a component through `ViewContainerRef.create`, because the next template function hasn't run yet and it hasn't had the chance to update the namespace. The result is that the root node of the new component will retain the wrong namespace and may not end up rendering at all (e.g. if we're trying to show a `div` inside the SVG namespace). This issue has the potential to affect a lot of apps, because all components inserted through the router also go through `ViewContainerRef.create`.

The `gulp format*` tasks have been broken since 5eb742621. These include
the `gulp format:enforce` task, which is what runs on CI to enforce
consistent code style. Here is what (I believe) happened:
- I assume formatting was failing in 5eb742621 (moving `zone.js` into
`angular/angular`). The reason must have been that
[this glob pattern][1] matches `packages/zone.js/` (which is a
directory) and passes it to `clang-format` claiming it is a file.
- I further assume that in an attempt to fix the issue,
`gulp-clang-format` was updated to the latest version (1.0.27) in
5eb742621.
- `gulp format:enforce` stopped complaining, so everyone thought
formatting was fine and moved on.
- Formatting still wasn't fine, but the task completed successfully
nevertheless 😱
- The reason is that angular/gulp-clang-format@55b697c5c (and subsequent
commits) changed the way the `done()` callback was called, leaving it
to `clang-format` to call it (while previously it was also called when
the associated stream ended).
- In the old version of `clang-format` that we are using (1.0.41), there
is a bug (which has been fixed in angular/clang-format@4cce2c4ee):
The callback is not called
[unless the process exits with an error][2].
One can also see that the `gulp format:enforce` task is not completed in
`gulp lint`. Example output from [build 374722][3]:

The Angular runtime frequently calls into user code (for example, when
writing to a property binding). Since user code can throw errors, calls to
it are frequently wrapped in a try-finally block. In Ivy, the following
pattern is common:
```typescript
enterView();
try {
callUserCode();
} finally {
leaveView();
}
```
This has a significant problem, however: `leaveView` has a side effect: it
calls any pending lifecycle hooks that might've been scheduled during the
current round of change detection. Generally it's a bad idea to run
lifecycle hooks after the application has crashed. The application is in an
inconsistent state - directives may not be instantiated fully, queries may
not be resolved, bindings may not have been applied, etc. Invariants that
the app code relies upon may not hold. Further crashes or broken behavior
are likely.
Frequently, lifecycle hooks are used to make assertions about these
invariants. When these assertions fail, they will throw and "swallow" the
original error, making debugging of the problem much more difficult.
This commit modifies `leaveView` to understand whether the application is
currently crashing, via a parameter `safeToRunHooks`. This parameter is set
by modifying the above pattern:
```typescript
enterView();
let safeToRunHooks = false;
try {
callUserCode();
safeToRunHooks = true;
} finally {
leaveView(..., safeToRunHooks);
}
```
If `callUserCode` crashes, then `safeToRunHooks` will never be set to `true`
and `leaveView` won't call any further user code. The original error will
then propagate back up the stack and be reported correctly. A test is added
to verify this behavior.

Our module resolution prefers `.js` files over `.d.ts` files because
occasionally libraries publish their typings in the same directory
structure as the compiled JS files, i.e. adjacent to each other.
The standard TS module resolution would pick up the typings
file and add that to the `ts.Program` and so they would be
ignored by our analyzers. But we need those JS files, if they
are part of the current package.
But this meant that we also bring in JS files from external
imports from outside the package, which is not desired.
This was happening for the `@fire/storage` enty-point
that was importing the `firebase/storage` path.
In this commit we solve this problem, for the case of imports
coming from a completely different package, by saying that any
file that is outside the package root directory must be an external
import and so we do not analyze those files.
This does not solve the potential problem of imports between
secondary entry-points within a package but so far that does
not appear to be a problem.

There are scenarios where it is not possible for ngcc to guess the format
or configuration of an entry-point just from the files on disk.
Such scenarios include:
1) Unwanted entry-points: A spurious package.json makes ngcc think
there is an entry-point when there should not be one.
2) Deep-import entry-points: some packages allow deep-imports but do not
provide package.json files to indicate to ngcc that the imported path is
actually an entry-point to be processed.
3) Invalid/missing package.json properties: For example, an entry-point
that does not provide a valid property to a required format.
The configuration is provided by one or more `ngcc.config.js` files:
* If placed at the root of the project, this file can provide configuration
for named packages (and their entry-points) that have been npm installed
into the project.
* If published as part of a package, the file can provide configuration
for entry-points of the package.
The configured of a package at the project level will override any

This commit breaks up these big mock file-systems into smaller more
focused chunks.
PR Close#30591
To improve cross platform support, all file access (and path manipulation)
is now done through a well known interface (`FileSystem`).
For testing a number of `MockFileSystem` implementations are provided.
These provide an in-memory file-system which emulates operating systems
like OS/X, Unix and Windows.
The current file system is always available via the static method,
`FileSystem.getFileSystem()`. This is also used by a number of static
methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass
`FileSystem` objects around all the time. The result of this is that one
must be careful to ensure that the file-system has been initialized before
using any of these static methods. To prevent this happening accidentally
the current file system always starts out as an instance of `InvalidFileSystem`,
which will throw an error if any of its methods are called.
You can set the current file-system by calling `FileSystem.setFileSystem()`.
During testing you can call the helper function `initMockFileSystem(os)`
which takes a string name of the OS to emulate, and will also monkey-patch
aspects of the TypeScript library to ensure that TS is also using the
current file-system.
Finally there is the `NgtscCompilerHost` to be used for any TypeScript
compilation, which uses a given file-system.
All tests that interact with the file-system should be tested against each
of the mock file-systems. A series of helpers have been provided to support
such tests:
* `runInEachFileSystem()` - wrap your tests in this helper to run all the
wrapped tests in each of the mock file-systems.
* `addTestFilesToFileSystem()` - use this to add files and their contents
to the mock file system for testing.
* `loadTestFilesFromDisk()` - use this to load a mirror image of files on
disk into the in-memory mock file-system.
* `loadFakeCore()` - use this to load a fake version of `@angular/core`
into the mock file-system.
All ngcc and ngtsc source and tests now use this virtual file-system setup.

In ViewEngine injecting a Renderer2 returns a renderer that is specific to the particular component, however in Ivy we inject the renderer for the parent view instead. This causes it to set incorrect `ngcontent` attributes when creating elements through the renderer.
The issue comes from the fact that the `Renderer2` is created according to the current `LView`, but because DI happens before we've entered the `LView` of the component that's injecting the renderer, we end up with one that's one level up. We work around the issue by finding the `LView` that corresponds to the `previousOrParentTNode` inside of the parent view and associating the `Renderer2` with it.

Previously, multiple ViewContainerRef instances (obtained by injecting
ViewContainerRef multiple times) each had private state that could be out of
sync with actual LContainer, if views were inserted/removed/queried across
the different instances. In particular each instance had its own array which
tracked ViewRefs inserted via that instance.
This commit moves the ViewRefs array onto the LContainer itself, so that it
can be shared across multiple ViewContainerRef instances. A test is added
that verifies ViewContainerRefs now provide a consistent view of the

Currently the `RecursiveAstVisitor` that is part of the template expression
parser does not _always_ properly pass through the context that can be
specified when visting a given expression. Only a handful of AST types
pass through the context while others are accidentally left out. This causes
unexpected and inconsistent behavior and basically makes the `context`
parameter not usable if the type of template expression is not known.

To provide some context: The implicit receiver is part of the
parsed Angular template AST. Any property reads in bindings,
interpolations etc. read from a given object (usually the component
instance). In that case there is an _implicit_ receiver which can also
be specified explicitly by just using `this`.
e.g.
```html
<ng-template>{{this.myProperty}}</ng-template>
```
This works as expected in Ivy and View Engine, but breaks in case the
implicit receiver is not used for property reads. For example:
```html
<my-dir [myFn]="greetFn.bind(this)"></my-dir>
```
In that case the `this` will not be properly translated into the generated
template function code because the Ivy compiler currently always treats
the `ctx` variable as the implicit receiver. This is **not correct** and breaks
compatibility with View Engine. Rather we need to ensure that we retrieve
the root context for the standalone implicit receiver similar to how it works
for property reads (as seen in the example above with `this.myProperty`)
Note that this requires some small changes to the `expression_converter`
because we only want to generate the `eenextContent()` instruction if the
implicit receiver is _actually_ used/needed. View Engine determines if that is the case by recursively walking through the converted output AST and
checking for usages of the `o.variable('_co')` variable ([see here][ve_check]). This would work too for Ivy, but involves most likely more code duplication
since templates are isolated in different functions and it another pass
through the output AST for every template expression.

In a derived service class with no decorator (and therefore no factory) of

Previously this logic had a bug where the factory function would be called
with no arguments, which would incorrectly create an instance of the base

correctness of this behavior.

Factory functions written by the compiler optionally allow an explicit type
to be passed. If called with this type, an instance of the given type will
be created instead of the type for which the factory was generated. This is
used to power inheritance of Angular types, as if the constructor of a class
is inherited from its superclass, then the factory function of the
superclass must be used (it has all the DI info) to construct an instance of
the derived class.
This commit adjusts typings in a few places to allow factory functions to be
called with this extra type parameter.

In older browsers such as IE10, inheritance of static properties on class
types is implemented by copying the properties. This makes hasOwnProperty
unreliable for checking if a static property is defined directly on a class
or is inherited. This causes problems when trying to read the
ngInjectableDef properties of inherited services, as in IE10 even inherited
definitions will appear to be local.

when a definition is read which doesn't belong to the type itself.

Currently undecorated classes are intentionally not processed
with ngcc. This is causing unexpected behavior because decorator
handlers such as `base_def.ts` are specifically interested in class
definitions without top-level decorators, so that the base definition
can be generated if there are Angular-specific class members.
In order to ensure that undecorated base-classes work as expected
with Ivy, we need to run the decorator handlers for all top-level
class declarations (not only for those with decorators). This is similar
to when `ngtsc` runs decorator handlers when analyzing source-files.

The usage of array spread syntax in source code may be downleveled to a
call to TypeScript's `__spread` helper function from `tslib`, depending

problematic for ngcc when it is processing ES5 formats, as the static
evaluator won't be able to interpret those calls.
A custom foreign function resolver is not sufficient in this case, as
`tslib` may be emitted into the library code itself. In that case, a
helper function can be resolved to an actual function with body, such
that it won't be considered as foreign function. Instead, a reflection
host can now indicate that the definition of a function corresponds with
a certain TypeScript helper, such that it becomes statically evaluable

definitions and to programmatically project nodes into the slots.
e.g.
```html
<ng-content></ng-content>
<ng-content></ng-content>
```
Using `ViewContainerRef#createComponent` allowed projecting
nodes into one of the projection defs (through index)
This no longer works with Ivy as the `projectionDef` instruction only
retrieves a list of selectors instead of also retrieving entries for
reserved projection slots which appear when using the default
selector multiple times (as seen above).
In order to fix this issue, the Ivy compiler now passes all
projection slots to the `projectionDef` instruction. Meaning that
there can be multiple projection slots with the same wildcard
selector. This allows multi-slot projection as seen in the
example above, and it also allows us to match the multi-slot node
projection order from View Engine (to avoid breaking changes).
It basically ensures that Ivy fully matches the View Engine behavior
except of a very small edge case that has already been discussed
in FW-886 (with the conclusion of working as intended).

Currently with Ivy, `ModuleWithProvider` providers are processed in order
of declaration in the `NgModule` imports. This technically makes makes
sense but is a potential breaking change as `ModuleWithProvider` providers
are processed after all imported modules in View Engine.
In order to keep the behavior of View Engine, the `r3_injector` is updated

fix(@schematics/angular): TypeScript related migrations should cater for BOM
In the CLI `UpdateRecorder` methods such as `insertLeft`, `remove` etc.. accepts positions which are not offset by a BOM. This is because when a file has a BOM a different recorder will be used https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/schematics/src/tree/recorder.ts#L72 which caters for an addition offset/delta.
The main reason for this is that when a developer is writing a schematic they shouldn't need to compute the offset based if a file has a BOM or not and is handled out of the box.
Example
```ts
recorder.insertLeft(5, 'true');
```
However this is unfortunate in the case if a ts SourceFile is used and one uses `getWidth` and `getStart` method they will already be offset by 1, which at the end it results in a double offset and hence the problem.

Two issues with DebugNode/DebugElement in Ivy were causing problems in user
tests.
1. The DebugNodes returned by Ivy were not actually instances of DebugNode.
This was due to an issue with the Ivy switch logic in debug_node.ts.
The declaration of the exported DebugNode reference was set to
`DebugNode__PRE_R3__ as any`. The cast prevented the Ivy switch transform
from detecting this as a switchable declaration. The transform cannot handle
arbitrary syntax, and exports *must* be of the form "const x = y__PRE_R3__;"
or they will not work. The cast to any in this case was not needed, so this
commit removes it.
2. DebugNodes returned by Ivy multiple times for the same element were not
reference-identical. This was previously considered a minor breaking change
in Ivy, but testing has shown that users depend on referential equality of
DebugNodes. This commit caches a DebugNode on a DOM node when first creating
it, to allow returning the same instance in subsequent operations.

The R3TargetBinder "binds" an Angular template AST, computing semantic
information regarding the template and making it accessible.
One of the binding passes previously had a bug, where for the following
template:
<div *ngIf="foo as foo"></div>
which desugars to:
<ng-template ngIf [ngIf]="foo" let-foo="ngIf">
<div></div>
</ng-template>
would have the `[ngIf]` binding processed twice - in both the scope which
contains the `<ng-template>` and the scope inside the template. The bug
arises because during the latter, `foo` is a variable defined by `let-foo`,
and so the R3TargetBinder would incorrectly learn that `foo` inside `[ngIf]`
maps to that variable.
This commit fixes the bug by only processing inputs, outputs, and
templateAttrs from `Template`s in the outer scope.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

DEPRECATION:
platform-webworker has been around since the initial release of Angular
version 2. It began as an experiment to leverage Angular's rendering
architecture and try something different: to run an entire web application
in a web worker.
We've learned a lot from this experiment, and have come to the conclusion
that pushing entire applications to run in a web worker is not a recipe for
success for most applications. This is due to a number of unresolved issues,
including:
* Poor or non-existent support for web worker APIs in web crawlers/indexers.
* Poor support in build and bundling tooling.
As a result, as of Angular version 8, we are deprecating the
`platform-webworker` APIs in Angular. This consists of both NPM packages,
`@angular/platform-webworker` and `@angular/platform-webworker-dynamic`.
Going forward, we will focus our efforts related to web workers around their
primary use case of offloading CPU-intensive but not critical work.

With Ivy, injecting a `ViewContainerRef` for a `<ng-container>` element
results in two comments generated in the DOM. One comment as host
element for the `ElementContainer` and one for the generated `LContainer`
which is needed for the created `ViewContainerRef`.
This is problematic as developers expect the same anchor element for
the `LContainer` and the `ElementContainer` in order to be able to move
the host element of `<ng-container>` without leaving the actual
`LContainer` anchor element at the original location.
This worked differently in View Engine and various applications might
depend on the behavior where the `ViewContainerRef` shares the anchor
comment node with the host comment node of the `<ng-container>`. For
example `CdkTable` from `@angular/cdk` moves around the host element of
a `<ng-container>` and also expects embedded views to be inserted next
to the moved `<ng-container>` host element.

BREAKING CHANGE
In PR #19558, we fixed a bug in `TestBed.overrideProvider` where
eager providers were not being instantiated correctly. However,
it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers
would not be instantiated. To assist in the transition, the
`TestBed.deprecatedOverrideProvider` method was temporarily
introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.
2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs
for the dependencies of the newly instantiated providers.

Context:
As part of the `test_docs_examples_ivy` job, we run 5 concurrent builds
on each VM (each for a different example/project). Additionally, all
example projects share the same `node_modules/` (via a symlink to
`aio/tools/examples/shared/node_modules/`), so all concurrent builds
operate on the same files.
Previously, we pre-ran ngcc with `--properties module` to process the
fesm5 bundles. Since we have switched to es2015 in 661a57d9e, we now
need the esm2015 bundles. As a result, the initial ngcc run is
redundant and ngcc runs again during each build (to process the fesm2015
bundles). Since there are 5 concurrent builds, we often end up with
multiple ngcc instances processing the same package and trying to write
to the same directories at the same time, causing a
`file already exists` error
This commit fixes it by pre-processing the esm2015 bundles, so there is
no need to re-run ngcc during each concurrent build.

using the following declaration:
```typescript
export declare class NgIf {
static ngTemplateGuard_ngIf<E>(dir: NgIf, expr: E): expr is NonNullable<E>
}
```
This works fine for usages such as `*ngIf="person"` but starts to introduce
false-positives when e.g. an explicit non-null check like
`*ngIf="person !== null"` is used, as the method invocation in the TCB
would not have the desired effect of narrowing `person` to become
non-nullable:
```typescript
if (NgIf.ngTemplateGuard_ngIf(directive, ctx.person !== null)) {
// Usages of `ctx.person` within this block would
// not have been narrowed to be non-nullable.
}
```
This commit introduces a new strategy for template guards to allow for the
binding expression itself to be used as template guard in the TCB. Now,
the TCB generated for `*ngIf="person !== null"` would look as follows:
```typescript
if (ctx.person !== null) {
// This time `ctx.person` will successfully have
// been narrowed to be non-nullable.
}
```
This strategy can be activated by declaring the template guard as a
property declaration with `'binding'` as literal return type.
See #30235 for an example where this led to a false positive.

In View engine it is possible to instantiate a service that that has no
`@Injectable` decorator as long as it satisfies one of:
1) It has no dependencies and so a constructor with no parameters.
This is already supported in Ivy.
2) It has no constructor of its own and sub-classes a service which has
dependencies but has its own `@Injectable` decorator. This second
scenario was broken in Ivy.
In Ivy, previous to this commit, if a class to be instantiated did not have
its own `@Injectable` decorator and did not provide a constructor of
its own, then it would be created using `new` with no arguments -
i.e. falling back to the first scenario.
After this commit Ivy correctly uses the `ngInjectableDef` inherited
from the super-class to provide the `factory` for instantiating the
sub-class.

In some cases where multiple navigations happen to the same URL, the router will not process a given URL. In those cases, we fall into logic that resets state for the next navigation. One piece of this resetting is to set the `browserUrlTree` to the most recent `urlAfterRedirects`i.
However, there was bug in this logic because in some cases the `urlAfterRedirects` is a stale value. This happens any time a URL won't be processed, and the previous URL will also not be processed. This creates unpredictable behavior, not the least of which ends up being a broken `back` button.
This PR kicks off new navigations with the current value the router assumes is in the browser. All the logic around how to handle future navigations is based on this value compared to the current transition, so it's important to kick off all new navigations with the current value so in the edge case described above we don't end up with an old value being set into `browserUrlTree`.

To support skipping analysis of a file containing a component
we need to know that none of the declarations that might affect

files that are in each declared class's `CompilationScope` via
a new method, `recordNgModuleScopeDependencies()`, that is called
after all the handlers have been "resolved".
Further, if analysis is skipped for a declared class, then we need
to recover the analysis from the previous compilation run. To
support this, the `IncrementalState` class has been updated to
expose the `MetadataReader` and `MetadataRegistry` interfaces.

to tell whether the given call expression actually causes the specified
arrow function to be executed synchronously or not. In order to be able

When working out the dependencies between entry-points
ngcc must parse the import statements and then resolve the

Previously ngcc used the node.js `require.resolve`, with some
hacking to resolve modules. This change refactors the `DependencyHost`
to use a new custom `ModuleResolver`, which is optimized for this use
case.

but at least the polyfills now uses the evergreen build of zones so we shaved off a few KB there.
PR Close#30183
Introduces a new Bazel test that allows us to inspect
what source-files contribute to a given bundled file
and how much bytes they contribute to the bundle size.
Additionally the size-tracking rule groups the size
data by directories. This allows us to compare size
changes in the scope of directories. e.g. a lot of
files in a directory could increase slightly in size, but
in the directory scope the size change could be significant
and needs to be reported by the test target.

Disables the injectable pipe migration until we can decide whether this is the right solution for Ivy. Rolling it out properly will involve a more detailed plan and more changes like updating the styleguide, scaffolding schematics etc.
Context for the new `test-migrations.json`: since we use the `migrations.json` both for the real migrations and for tests, it doesn't allow us to disable a schematic, but continue running its tests. This change adds the test-specific file so that we can continue running the `injectable-pipe` tests, even though the schematic itself is disabled.
PR Close#30180
Currently the injectable pipe schematic generates invalid imports like `import import { Pipe, PipeTransform, Injectable } from '@angular/core'; from '@angular/core';`. The issue wasn't caught by the unit tests, because the invalid import still contains the valid one.
Fixes#30159.

Currently when working on Windows, it's not possible to accept a new
golden for a `symbol-extractor` Bazel test. This is because the generated
executable output from the `nodejs_binary` rule (without a macro) misses
a Windows executable wrapper that sets up the proper environment
variables for the runfiles. Causing the following failure on Windows:
```
>>>> FAIL: RUNFILES environment variable is not set. <<<<
```

This PR removes `tsserverlibrary` from rollup globals since the symbol
should not appear by the time rollup is invoked. `tsserverlibrary` is
used for types only, so the import statement should not be emitted by
tsc.

Previously, the `aio_monitoring_stable` job (which runs tests against
https://angular.io/) was using the tests from the master branch. As a
result, if the master branch included changes in those tests that were
not yet backported to the stable branch (and thus deployed to
https://angular.io/), the tests would fail.
This commit fixes this by using the tests from the stable branch to test
against https://angular.io/.
Fixes#30101
PR Close#30110
Previously, the `aio_monitoring` job was testing both the stable
(https://angular.io/) and the @next (https://next.angular.io/) versions.
This commit splits the tests into two separate jobs (still run as part
of the same workflow). This speeds up the tests (since the two jobs can
now run in parallel) and makes it easier to isolate failures (e.g.
identify which branch is failing, disable one of the two, etc.).
(Credits to @petebacondarwin 😉)
PR Close#30110
The job started failing for https://angular.io/, due to changes in tests
that only affected https://next.angular.io/, and was disabled in #30102.
This commit re-enables the job (since it does not block anything and it
will be fixed in a subsequent commit).

When the workspace node_modules are not installed outside of bazel context the api guardian tests fails because the tree artifacts files are not symlinked in windows.
We need to pass the node module location in the node_path
PR Close#30105
This change addresses several issues with ts-api-guardian and public api guards related tests in Windows
The fixes contain 3 main changes:
1) In `stripExportPattern` - replace `^` with `^^^^` in RegExp due to a double escaping requirment under Windows. Note that under Linux this the extra character has no effect because it's still a valid RegExp in Js.
2. Force `*.patch` files to always be with a LF line sequence instead of CRLF in windows
3. When adding JSDoc comments consider the presence of a carriage return in a line new feed

We recently had an unexpected size regression in the hello world

Prior to this commit, we were pulling DebugNode and DebugElement
into production builds because BrowserModule automatically pulled
in NgProbe and thus getDebugNode. In Ivy, this is not necessary
because Ivy has its own set of debug utilities. We should use these
existing tools instead of NgProbe.
This commit adds an Ivy switch so we do not pull in NgProbe utilities
when running with Ivy. This saves us ~8KB in prod builds.

* **core:** deprecate integration with the Web Tracing Framework (WTF) ([#30642](https://github.com/angular/angular/issues/30642)) ([b408445](https://github.com/angular/angular/commit/b408445))
* **bazel:** @bazel/typescript is now a peerDependency of @angular/bazel so users of @angular/bazel must add @bazel/typescript to their package.json
* **bazel:** `ng_module` now depends on a minimum of build_bazel_rules_nodejs 0.27.12
* **core:** In Angular version 8, it's required that all `@ViewChild` and `@ContentChild`
queries have a `'static'` flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see
[static query migration guide](https://v8.angular.io/guide/static-query-migration) for more details.
`@ViewChildren` and `@ContentChildren` queries are always dynamic, and so are
unaffected.
*`TestBed.get()` has two signatures, one which is typed and another which accepts and returns `any`. The signature for `any` is deprecated; all usage of `TestBed.get()` should go through the typed API. This mainly affects string tokens
(which aren't supported) and abstract class tokens.
Before:
```ts
TestBed.configureTestingModule({
providers: [{provide: "stringToken", useValue: new Service()}],
});
let service = TestBed.get("stringToken"); // type any
```
After:
```ts
const SERVICE_TOKEN = new InjectionToken<Service>("SERVICE_TOKEN");
TestBed.configureTestingModule({
providers: [{provide: SERVICE_TOKEN, useValue: new Service()}],
});
let service = TestBed.get(SERVICE_TOKEN); // type Service
```
* **core:** Certain elements (like `<tr>` or `<col>`) require parent elements to be of a certain type by the HTML specification
(ex. `<tr>` can only be inside `<tbody>` / `<thead>`). Before this change Angular template parser was auto-correcting
"invalid" HTML using the following rules:
- `<tr>` would be wrapped in `<tbody>` if not inside `<tbody>`, `<tfoot>` or `<thead>`;
- `<col>` would be wrapped in `<colgroup>` if not inside `<colgroup>`.
This mechanism of automatic wrapping / auto-correcting was problematic for several reasons:
- it is non-obvious and arbitrary (ex. there are more HTML elements that have rules for parent type);
- it is incorrect for cases where `<tr>` / `<col>` are at the root of a component's content, ex.:
```html
<projecting-tr-inside-tbody>
<tr>...</tr>
</projecting-tr-inside-tbody>
```
In the above example the `<projecting-tr-inside-tbody>` component could be "surprised" to see additional
`<tbody>` elements inserted by Angular HTML parser.
* **http:** The deprecated @angular/http package has been removed, the @angular/common/http package should be used instead.
For details on how to migrate, please refer to [the deprecations guide](https://angular.io/guide/deprecations#angularhttp).
* TypeScript 3.1 and 3.2 are no longer supported.
Please update your TypeScript version to 3.4, as version 3.3 is also not supported.
