We previously disabled this test because we did not yet have
static query support in Ivy and the planned API would be
slightly different. Now that a static query flag is available
that works in both View Engine and Ivy, the test has been

PR Close#28832
Prior to this commit, the timing of `ViewChild`/`ContentChild` query
resolution depended on the results of each query. If any results
for a particular query were nested inside embedded views (e.g.
*ngIfs), that query would be resolved after change detection ran.
Otherwise, the query would be resolved as soon as nodes were created.
This inconsistency in resolution timing had the potential to cause
confusion because query results would sometimes be available in
ngOnInit, but sometimes wouldn't be available until ngAfterContentInit
or ngAfterViewInit. Code depending on a query result could suddenly
stop working as soon as an *ngIf or an *ngFor was added to the template.
With this commit, users can dictate when they want a particular
`ViewChild` or `ContentChild` query to be resolved with the `static`
flag. For example, one can mark a particular query as `static: false`
to ensure change detection always runs before its results are set:
```ts
@ContentChild('foo', {static: false}) foo !: ElementRef;
```
This means that even if there isn't a query result wrapped in an
*ngIf or an *ngFor now, adding one to the template later won't change
the timing of the query resolution and potentially break your component.
Similarly, if you know that your query needs to be resolved earlier
(e.g. you need results in an ngOnInit hook), you can mark it as
`static: true`.
```ts
@ViewChild(TemplateRef, {static: true}) foo !: TemplateRef;
```
Note: this means that your component will not support *ngIf results.
If you do not supply a `static` option when creating your `ViewChild` or
`ContentChild` query, the default query resolution timing will kick in.
Note: This new option only applies to `ViewChild` and `ContentChild`
queries, not `ViewChildren` or `ContentChildren` queries, as those types
already resolve after CD runs.

Currently if developers use call expressions in their static
class members ([like we do in Angular](https://github.com/angular/angular/blob/master/packages/core/src/change_detection/differs/keyvalue_differs.ts#L121)),
the metadata that is generated for flat modules is invalid. This
is because the metadata bundler logic currently does not handle
call expressions in static class members and the symbol references
are not rewritten to avoid relative paths in the bundle.
Static class members using a call expression are not relevant for
the ViewEngine AOT compilation, but it is problematic that the
bundled metadata references modules using their original relative
path. This means that the bundled metadata is no longer encapsulated
and depends on other emitted files to be emitted in the proper place.
These incorrect relative paths can now cause issues where NGC
looks for the referenced symbols in the incorrect path. e.g.
```
src/
| lib/
| index.ts -> References the call expression using `../../di`
```
Now the metadata looks like that:
```
node_modules/
| @angular/
-- | core/
-- -- | core.metadata.json -> Says that the call expr. is in `../../di`.
| di/
```
Now if NGC tries to use the metadata files and create the summary files,
NGC resolves the call expression to the `node_modules/di` module. Since
the "unexpected" module does not contain the desired symbol, NGC will
error out.
We should fix this by ensuring that we don't ship corrupted metadata
to NPM which contains relative references that can cause such
failures (other imports can be affected as well; it depends on what
modules the developer has installed and how we import our call
expressions).

BREAKING CHANGE
Previous to this change, when a control was reset, value and status change
events would be emitted before the control was reset to pristine. As a
result, if one were to check a control's pristine state in a valueChange
listener, it would appear that the control was still dirty after reset.
This change delays emission of value and status change events until after
controls have been marked pristine. This means the pristine state will be
reset as expected if one checks in a listener.
Theoretically, there could be applications depending on checking whether a
control *used to be dirty*, so this is marked as breaking. In these cases,
apps should cache the state on the app side before calling reset.

The ultimate goal of this commit is to make use of fileNameToModuleName to
get the module specifier to use when generating an import, when that API is
available in the CompilerHost that ngtsc is created with.
As part of getting there, the way in which ngtsc tracks references and
generates import module specifiers is refactored considerably. References
are tracked with the Reference class, and previously ngtsc had several
different kinds of Reference. An AbsoluteReference represented a declaration
which needed to be imported via an absolute module specifier tracked in the
AbsoluteReference, and a RelativeReference represented a declaration from
the local program, imported via relative path or referred to directly by
identifier if possible. Thus, how to refer to a particular declaration was
encoded into the Reference type _at the time of creation of the Reference_.
This commit refactors that logic and reduces Reference to a single class
with no subclasses. A Reference represents a node being referenced, plus
context about how the node was located. This context includes a
"bestGuessOwningModule", the compiler's best guess at which absolute
module specifier has defined this reference. For example, if the compiler
arrives at the declaration of CommonModule via an import to @angular/common,
then any references obtained from CommonModule (e.g. NgIf) will also be
considered to be owned by @angular/common.
A ReferenceEmitter class and accompanying ReferenceEmitStrategy interface
are introduced. To produce an Expression referring to a given Reference'd
node, the ReferenceEmitter consults a sequence of ReferenceEmitStrategy
implementations.
Several different strategies are defined:
- LocalIdentifierStrategy: use local ts.Identifiers if available.
- AbsoluteModuleStrategy: if the Reference has a bestGuessOwningModule,
import the node via an absolute import from that module specifier.
- LogicalProjectStrategy: if the Reference is in the logical project
(is under the project rootDirs), import the node via a relative import.
- FileToModuleStrategy: use a FileToModuleHost to generate the module
specifier by which to import the node.
Depending on the availability of fileNameToModuleName in the CompilerHost,
then, a different collection of these strategies is used for compilation.

Previously, ngtsc would throw an error if two decorators were matched on
the same class simultaneously. However, @Injectable is a special case, and
it appears frequently on component, directive, and pipe classes. For pipes
in particular, it's a common pattern to treat the pipe class also as an
injectable service.
ngtsc actually lacked the capability to compile multiple matching
decorators on a class, so this commit adds support for that. Decorator
handlers (and thus the decorators they match) are classified into three
categories: PRIMARY, SHARED, and WEAK.
PRIMARY handlers compile decorators that cannot coexist with other primary
decorators. The handlers for Component, Directive, Pipe, and NgModule are
marked as PRIMARY. A class may only have one decorator from this group.
SHARED handlers compile decorators that can coexist with others. Injectable
is the only decorator in this category, meaning it's valid to put an
@Injectable decorator on a previously decorated class.
WEAK handlers behave like SHARED, but are dropped if any non-WEAK handler
matches a class. The handler which compiles ngBaseDef is WEAK, since
ngBaseDef is only needed if a class doesn't otherwise have a decorator.
Tests are added to validate that @Injectable can coexist with the other
decorators and that an error is generated when mixing the primaries.
PR Close#28523
In the past, @Injectable had no side effects and existing Angular code is
therefore littered with @Injectable usage on classes which are not intended
to be injected.
A common example is:
@Injectable()
class Foo {
constructor(private notInjectable: string) {}
}
and somewhere else:
providers: [{provide: Foo, useFactory: ...})
Here, there is no need for Foo to be injectable - indeed, it's impossible
for the DI system to create an instance of it, as it has a non-injectable
constructor. The provider configures a factory for the DI system to be
able to create instances of Foo.
Adding @Injectable in Ivy signifies that the class's own constructor, and
not a provider, determines how the class will be created.
This commit adds logic to compile classes which are marked with @Injectable
but are otherwise not injectable, and create an ngInjectableDef field with
a factory function that throws an error. This way, existing code in the wild
continues to compile, but if someone attempts to use the injectable it will
fail with a useful error message.
In the case where strictInjectionParameters is set to true, a compile-time
error is thrown instead of the runtime error, as ngtsc has enough
information to determine when injection couldn't possibly be valid.

With #28594 we refactored the `@angular/compiler` slightly to
allow opting out from external symbol re-exports which are
enabled by default.
Since symbol re-exports only benefit projects which have a
very strict dependency enforcement, external symbols should
not be re-exported by default as this could grow the size of
factory files and cause unexpected behavior with Angular's
AOT symbol resolving (e.g. see: #25644).
Note that the common strict dependency enforcement for source
files does still work with external symbol re-exports disabled,
but there are also strict dependency checks that enforce strict
module dependencies also for _generated files_ (such as the
ngfactory files). This is how Google3 manages it's dependencies
and therefore external symbol re-exports need to be enabled within
Google3.
Also "ngtsc" also does not provide any way of using external symbol
re-exports, so this means that with this change, NGC can partially
match the behavior of "ngtsc" then (unless explicitly opted-out).
As mentioned before, internally at Google symbol re-exports need to
be still enabled, so the `ng_module` Bazel rule will enable the symbol
re-exports by default when running within Blaze.

Previously, using a pipe in an input binding on an ng-template would
evaluate the pipe in the context of node that was processed before the
template. This caused the retrieval of e.g. ChangeDetectorRef to be
incorrect, resulting in one of the following bugs depending on the
template's structure:
1. If the template was at the root of a view, the previously processed
node would be the component's host node outside of the current view.
Accessing that node in the context of the current view results in a crash.
2. For templates not at the root, the ChangeDetectorRef injected into the
pipe would correspond with the previously processed node. If that node
hosts a component, the ChangeDetectorRef would not correspond with the
view that the ng-template is part of.
The solution to the above problem is two-fold:
1. Template compilation is adjusted such that the template instruction
is emitted before any instructions produced by input bindings, such as
pipes. This ensures that pipes are evaluated in the context of the
template's container node.
2. A ChangeDetectorRef can be requested for container nodes.

During analysis, the `ComponentDecoratorHandler` passes the component
template to the `parseTemplate()` function. Previously, there was little or
no information about the original source file, where the template is found,
passed when calling this function.
Now, we correctly compute the URL of the source of the template, both
for external `templateUrl` and in-line `template` cases. Further in the
in-line template case we compute the character range of the template
in its containing source file; *but only in the case that the template is
a simple string literal*. If the template is actually a dynamic value like
an interpolated string or a function call, then we do not try to add the
originating source file information.
The translator that converts Ivy AST nodes to TypeScript now adds these
template specific source mappings, which account for the file where
the template was found, to the templates to support stepping through the
template creation and update code when debugging an Angular application.
Note that some versions of TypeScript have a bug which means they cannot
support external template source-maps. We check for this via the
`canSourceMapExternalTemplates()` helper function and avoid trying to
add template mappings to external templates if not supported.

the body of the function, and not the arguments, which messes
up line and column positions for source mapping for instance.

behaviour.

parsing of text (e.g. HTML, Angular templates, CSS, i18n)
into an AST for further processing into a single `options`
hash.
This makes the code cleaner and more readable, but also
enables us to support further options to parsing without
triggering wide ranging changes to code that should not
be affected by these new options. Specifically, it will let
us pass information about the placement of a template
that is being parsed in its containing file, which is essential
for accurate SourceMap processing.

We currently face a lot of flakiness with our
Saucelabs CI jobs. These randomly exceed the 10min
CircleCI no-output limit because something throws
off `sauce-connect` in a long-lasting loop where
it tries to connect to some of their Saucelabs
servers. The initial assumption from the Saucelabs
team was that we might have some invalid firewall
rules, but this does not answer why this happens
_randomly_, so the latest update from the support
is that there have been some changes in the latest
version of `sauce-connect` version that **could**
cause this flakiness.
I've manually did multiple test runs and was only
able to reproduce the issues with v4.5.3 (latest
version), so it might be worth downgrading to
v4.5.1. This is also what the Saucelabs support
proposed us to do (though it's not guaranteed that
v4.5.1 is unaffected by the same issue)

Prior to this change in Ivy we had strict check that disabled non-unique #localRefs usage within a given template. While this limitation was technically present in View Engine, in many cases View Engine neglected this restriction and as a result, some apps relied on a fact that multiple non-unique #localRefs can be defined and utilized to query elements via @ViewChild(ren) and @ContentChild(ren). In order to provide better compatibility with View Engine, this commit removes existing restriction.
As a part of this commit, are few tests were added to verify VE and Ivy compatibility in most common use-cases where multiple non-unique #localRefs were used.

Currently external static symbols which are referenced by AOT
compiler generated code, will be re-exported in the corresponding
`.ngfactory` files.
This way of handling the symbol resolution has been introduced in
favor of avoding dynamically generated module dependencies. This
behavior therefore avoids any strict dependency failures.
Read more about a particular scenario here: https://github.com/angular/angular/issues/25644#issuecomment-458354439
Now with `ngtsc`, this behavior has changed since `ngtsc` just
introduces these module dependencies in order to properly reference
the external symbol from its original location (also eliminating the need
for factories). Similarly we should provide a way to use the same
behavior with `ngc` because the downside of using the re-exported symbol
resolution is that user-code transformations (e.g. the `ngInjectableDef`
metadata which is added to the user source code), can resolve external
symbols to previous factory symbol re-exports. This is a critical issue
because it means that the actual JIT code references factory files in order
to access external symbols. This means that the generated output cannot
shipped to NPM without shipping the referenced factory files.
A specific example has been reported here: https://github.com/angular/angular/issues/25644#issue-353554070

Previously, `ng-packages-installer` would replace the version ranges for
all dependencies that were peer dependencies of an Angular package with
the version range used in the Angular package. This effectively meant
that the pinned version (from `yarn.lock`) for that dependency was
ignored (even if the pinned version satisfied the new version range).
This commit reduces non-determinism in CI jobs using the locally built
Angular packages by always using pinned versions of dependencies for
Angular package peer dependencies if possible.
For example, assuming the following versions for the RxJS dependency:
- **aio/package.json**: `rxjs: ^6.3.0`
- **aio/yarn.lock**: `rxjs@^6.3.0: 6.3.3`
- **@angular/core#peerDependencies**: `rxjs: ^6.0.0`
...the following versions would be used with `ng-packages-installer`:
- Before this commit:
- **aio/package.json**: `rxjs: ^6.0.0`
- **node_modules/rxjs/**: `6.4.0` (latest version satisfying `^6.0.0`)
- After this commit:
- **aio/package.json**: `rxjs: ^6.3.0`
- **node_modules/rxjs/**: `6.3.3` (because it satisfies `^6.0.0`)

`ng-packages-installer` can be used to replace Angular packages with
locally built ones (from `dist/packages-dist/`) along with their peer
dependencies.
Previously, in order to achieve this, `yarn install` was called with the
`--no-lockfile` option, which resulted in installing the latest versions
of all dependencies (including transitive ones) permitted by the
corresponding version ranges in `package.json` files. As a result, newly
released versions would be picked, resulting in unexpected,
non-deterministic breakages in CI.
This commit calls `yarn install` with the `--pure-lockfile` option
instead. As a result, only the Angular packages (for which the locally
built ones are used) and their peer dependencies are unpinned; the
pinned versions from `yarn.lock` are used for all other (direct and
transitive) dependencies.
While this does not eliminate non-determinism across builds, it
significantly reduces it.

When we first started writing tests for Ivy, we did not yet have a
compatible compiler. For this reason, we set up the Ivy runtime tests
to run with generated code that we wrote by hand (instead of real code
generated by the compiler).
Now that we have a working Ivy compiler and TestBed infrastructure
that is compatible with Ivy, we should start writing integration
tests that leverage them (no more handwritten generated code!). This
will prevent bugs where the compiler code and runtime code become
out of sync (which is easy if they are tested separately). And
eventually, we should migrate all the existing runtime tests in
"core/test/render3" to TestBed and ngtsc.
To kick off this effort, this commit migrates some existing tests
from "core/test/render3/exports_spec.ts" and saves them in a new file

i18n instructions create text nodes dynamically and save them between bindings and the expando block in `LView`. e.g., they try to create the following order in `LView`.
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando (dirs, injectors) -- |
```
Each time a new text node is created, it is pushed to the end of the array and the `expandoStartIndex` marker is incremented, so the section begins slightly later. This happens in `allocExpando`.
This is fine if no directives have been created yet. The end of the array will be in the "dynamic text node" section.
| -- elements -- | -- bindings -- | -- dynamic i18n text -- |
However, this approach doesn't work if dynamic text nodes are created after directives are matched (for example when the directive uses host bindings). In that case, there are already directives and injectors saved in the "expando" section. So pushing to the end of `LView` actually pushes after the expando section. What we get is this:
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando -- | -- dynamic i18n text-- |
```
In this case, the `expandoStartIndex` shouldn't be incremented because we are not inserting anything before the expando section (it's now after the expando section). But because it is incremented in the code right now, it's now pointing to an index in the middle of the expando section.
This PR fixes that so that we only increment the `expandoStartIndex` if nothing was pushed into the expando section.

Ivy allows Components to extend Directives (but not the other way around) and as a result we may have Component and Directive annotations present at the same time.

We can safely remove the `{Branch}` variable from the cache key because

project, the node_modules directory is actually one level above the
project path.
This PR fixes the bug by resolving node_modules with require.resolve().
It requires @bazel/bazel v0.22.1 because previous versions do not have
index.js or main field in package.json and would cause node module
resolution to fail.
This has been tested with both bazel and ibazel.

In 7cb8396, we improved the symbol test to remove suffixes from
the output, so "CIRCULAR$1" became "CIRCULAR". However, the logic
that checked for extra symbols depended on each symbol being unique.
If multiple symbols with the same name were added (e.g. pulled in
from separate files), they would be added to the map as "extras",
even if they were marked as expected in the golden file.
This commit updates the symbol checking logic to take multiple
symbols with the same name into account.

Previously, attempting to destroy a view with listeners more than once
throws an error during event listener cleanup. This happens because
`cleanup` field on the `TView` has already been cleared out by the time
the second destruction runs.
The `destroyed` flag on LView was previously being set in the `destroyLView` function,
but this flag was never _checked_ anywhere in the codebase. This commit
moves _setting_ this flag to the `cleanupView` function, just before
destroy hooks are called. This is necessary because the destroy hooks
can contain arbitrary user code, such as (surprise!) attempting to
destroy the view (again). We also add a check to `destroyLView` to skip
already-destroyed views. This prevents the cleanup code path from running twice.

With the release of @angular/bazel v7.2.3, the npm install step right
after `ng new` installs this version. However there is a bug in the
builder which results in bazel executable not found.
This bug was not discovered before because the dependencies of the
project created by `ng new` are not pinned.
The fix is to pin the version of @angular/bazel to 7.2.2 which relies on
global installation of bazel.

In View Engine, we supported @Input and @ContentChild annotations
on the same property. This feature was somewhat brittle because
it would only work for static queries, so it would break if a
content child was passed in wrapped in an *ngIf. Due to the
inconsistent behavior and low usage both internally and externally,
we will likely be deprecating it in the next version, and it does
not make sense to perpetuate it in Ivy.
This commit ensures that we now throw in Ivy if we encounter the

When testing whether `value` is an object, use the ideal sequence of
strictly not equal to `null` followed by `typeof value === 'object'`
consistently. Specifically there's no point in using double equal with
`null` since `undefined` is ruled out by the `typeof` check.
Also avoid the unnecessary ToBoolean check on `value.ngOnDestroy` in
`hasOnDestroy()`, since the `typeof value.ngOnDestroy === 'function'`
will only let closures pass and all closures are truish (with the
notable exception of `document.all`, but that shouldn't be relevant
for the `ngOnDestroy` hook).

Prior to this change contentQueriesRefresh functions that represent refresh logic for @ContentQuery list were not composable, which caused problems in case one Directive inherits another one and both of them contain Content Queries.

In some cases, calling getSourceFile() on a node from within a TS

PR Close#28412
By its nature, Ivy alters the import graph of a TS program, adding imports
where template dependencies exist. For example, if ComponentA uses PipeB
in its template, Ivy will insert an import of PipeB into the file in which
ComponentA is declared.
Any insertion of an import into a program has the potential to introduce a
cycle into the import graph. If for some reason the file in which PipeB is
declared imports the file in which ComponentA is declared (maybe it makes
use of a service or utility function that happens to be in the same file as
ComponentA) then this could create an import cycle. This turns out to
happen quite regularly in larger Angular codebases.
TypeScript and the Ivy runtime have no issues with such cycles. However,
other tools are not so accepting. In particular the Closure Compiler is
very anti-cycle.
To mitigate this problem, it's necessary to detect when the insertion of
an import would create a cycle. ngtsc can then use a different strategy,
known as "remote scoping", instead of directly writing a reference from
one component to another. Under remote scoping, a function
'setComponentScope' is called after the declaration of the component's
module, which does not require the addition of new imports.

This commit implements a cycle detector which looks at the import graph of

Users should be able to add Bazel workspace to an existing project.
The current approach assumes that the schematics is working on the same

used to run the `@angular/bazel` schematic. Even if a different version

TestBed.compileComponents has always been an async API. However,

ngcc's reflection host needs to be able to determine all members of a
class, which it does by using the `ts.Symbol` from TypeScript's
TypeChecker. Such Symbol however may represent multiple class members
in the case of accessors; an equally named getter/setter accessor pair
is combined into a single `ts.Symbol`.
This commit introduces logic to recognize such accessors in order for
both the getter and setter to be considered as class member, similar to
ngtsc's behavior when operating on original TypeScript code.
One difference wrt the TypeScript host is that ngcc cannot see to which
accessor originally had any decorators applied to them, as decorators
are applied to the property descriptor in general, not a specific accessor.
If an accessor has both a setter and getter, any decorators are only
attached to the setter member.
PR Close#28357
Prior to this change, accessor functions for getters and setters would
not be considered as class member, as their declaration is vastly
different from ES2015 syntax.
With this change, the ES5 reflection host has learned to recognize the
downleveled syntax for accessors, allowing for them to be considered as
class member once again.

There are cases where we should check an element injector but don't go
into the associated module injector if a token is not found. In both the
view engine and ngIvy this is acheived by passing the
`NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR` as the `notFoundValue`.
Before this fix the view engine and ngIvy were using different objects to
represent `NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR`. This was causing problems
as ngUpgrade is using `NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR` const in its
`NgAdapterInjector` to prevent searching of module injectors.
This commit makes sure that ngIvy is using the same object to represent
`NOT_FOUND_CHECK_ONLY_ELEMENT_INJECTOR` as the view engine.

Before this commit we were creating a "fake" TNode for each and every
projectable node passed during dynamic component creation. This approach
had several problems:
- the existing TView structure had to be mutated to accomodate new TNodes and
it was very easy to "corrupt" TView / TNode data structures;
- TNodes are not really needed to fully support projectable nodes so we were
creating objects and updating existing data structures for nothing.
This commit changes the approach so we don't create "fake" TNodes for projectable
nodes but instead we process projectable nodes directly in the projection instruction.
As a result we've got less code, less object allocation and - as a bonus - we fix few
bugs where TView / TNode data structures were corrupted when using projectable nodes.

This commit changes the partial evaluation mechanism to propagate
DynamicValue errors internally during evaluation, and not to "poison"
entire data structures when a single value is dynamic. For example,
previously if any entry in an array was dynamic, evaluating the entire
array would return DynamicValue. Now, the array is returned with only
the specific dynamic entry as DynamicValue.
Instances of DynamicValue also report the node that was determined to
be dynamic, as well as a potential reason for the dynamic-ness. These
can be nested, so an expression `a + b` may have a DynamicValue that
indicates the 'a' term was DynamicValue, which will itself contain a
reason for the dynamic-ness.
This work was undertaken for the implementation of listLazyRoutes(),
which needs to partially evaluate provider arrays, parts of which are
dynamic and parts of which contain useful information.

Previous to this change, the isStylingContext() function was improperly
returning true for LContainers because it used the presence of an array
at index 2 to determine whether it was a styling context. Unfortunately,
LContainers also contain arrays at index 2, so this would return a false
positive. This led to other errors down the line because we would treat
nodes with containers as if they already had styling contexts (even if
they did not), so the proper initialization logic for styling contexts
was not run.
This commit fixes the isStylingContext() function to use LCONTAINER_LENGTH
as a marker rather than the presence of an array, which in turn fixes
host bindings to styles on nodes with containers.

There were two issues with multiple ICU expressions in the same i18n block:
- the regexp that was used to parse the text wasn't able to handle multiple ICU expressions, I've replaced it with parsing the text and searching for brackets (which is what we ended up doing in the end anyway)
- we allocate node indexes for nodes generated by the ICU expressions which increases the expando value, but we would create the nodes for those cases during the update phase. In the mean time we would create some nodes during the creation phase (comment nodes for ICU expressions, text nodes, ...) with an auto increment index. This means that any node created after an ICU expression would get the following index value, but the ICU case nodes expected to use the same index as well... There was a mismatch between the auto generated index, and the expected index which was causing problems when we needed to select those nodes for updates later on. To fix it, I've added the expected node index to the list of mutate codes that we generate, and we do not use an auto increment value anymore.

The implementation of the `compileComponents` method for `TestBedRender3` was missing.
We now pass each component through `resolveComponentResources` when `TestBed.compileComponents` is called so that `templateUrl` and `styleUrls` can be resolved asynchronously and used once `TestBed.createComponent` is called.
The component's metadata are overriden in `TestBed` instead of mutating the original metadata like this is the case outside of TestBed.

With the update to TypeScript 3.2.x, a big issue seems to have appeared for downstream Bazel users. If the downstream user still uses a lower TypeScript version, normal Bazel targets using the `ng_module` rule are still compiled with the correct/old TypeScript version (assuming they set the `node_modules` attribute properly).
But, if they build the previous Bazel targets by specifying them within a `ng_package` rule, the TypeScript version from the Angular `workspace` is being used for the replayed ESM5 compilation. This is because we resolve the replay compiler to `ngc_wrapped` or `tsc_wrapped` Bazel executables which are defined as part of the `angular` workspace. This means that the compilers are different if the downstream user uses `ngc-wrapped` from the `@npm` repository because the replayed compilation would use the compiler with `@ngdeps//typescript`.
In order to fix this, we should just use the compiler that is defined in the `@angular//BUILD.bazel` file. This target by defaults to the "@npm" workspace which is working for downstream users. This is similar to how it is handled for `tsc-wrapped`. `tsc-wrapped` works as expected for downstream users.
**Note**: This is not the ideal solution because ideally we would
completely respect the `compiler` option from the base `ng_module`, but
this is not possible in a hermetic way, unless we somehow accept the
`compiler` as an attribute that builds all transitive deps. This is
something we should explore in the future. For now, we just fix this in
a reasonable way that is also used for `tsc_wrapped` from the TypeScript
rules.

When an @NgModule decorator executes, the module is added to a queue in
render3/jit/module.ts. Reading an ngComponentDef property causes this queue
to be flushed, ensuring that the component gets the correct module scope
applied.
In before_each.ts, a global beforeEach is added to all Angular tests which
calls TestBed.resetTestingModule() prior to running each test. This in turn
clears the module compilation queue (which is correct behavior, as modules
declared within the test should not leak outside of it via the queue).
So far this is okay. But before the first test runs, the module compilation
queue is full of modules declared in global scope. No definitions have been
read, so no flushes of the queue have been triggered. The global beforeEach
triggers a reset of the queue, aborting all of the in-progress global
compilation, breaking those classes when they're later used in tests.
This commit adds logic to TestBedRender3 to respect the state of the module
queue before the TestBed is first initialized or reset. The queue is flushed
prior to such an operation to ensure global compilation is allowed to finish
properly.

An @NgModule with invalid provider declarations produces errors under
normal circumstances. However, within the TestBed two small issues with
provider overrides interfered with the correct production of these errors:
1. a 'null' provider object caused a premature crash when the TestBed

2. the array of providers would have an empty override array appended to it
for each input provider, which would pollute the error messages produced

In this refactoring, this rewriting logic is moved out of the ImportManager

of the interface:
* NoopImportRewriter, used for compiling all non-core packages.
* R3SymbolsImportRewriter, used when ngtsc compiles @angular/core.
* NgccFlatImportRewriter, used when ngcc compiles @angular/core (special
logic is needed because ngcc has to rewrite imports in flat bundles
differently than in non-flat bundles).

These tests validate the ability of the View Engine TestBed to consume
summary metadata, a mechanism which allows the TestBed to use
AOT-compiled components & directives in tests. It achieves this through
two operations which are independently obsolete in Ivy:
1. It injects CompileMetadataResolver, a View Engine specific compiler
internal class which extracts global analysis metadata from classes,
and uses it to construct summary metadata. This happens in a
beforeEach() block which calls createSummaries().
2. It uses TestBed.initTestEnvironment to pass summary metadata to the
TestBed itself. Any such metadata is ignored in Ivy.
Operation #1 makes it impossible to run these tests under Ivy, as the
CompileMetadataResolver is not available with an Ivy compiler.
Ivy itself does not rely on summary data, and the R3TestBed can depend
directly on AOT compiled components without it. Thus, the spirit of thes
tests is obsolete in an Ivy world.

A constructor function may have been "synthesized" by TypeScript during
JavaScript emit, in the case no user-defined constructor exists and e.g.

synthetic constructor.
This commit adds identification of such constructors as ngcc needs to be
able to tell if a class did originally have a constructor in the
TypeScript source. When a class has a superclass, a synthesized
constructor must not be considered as a user-defined constructor as that
prevents a base factory call from being created by ngtsc, resulting in a
factory function that does not inject the dependencies of the superclass.
Hence, we identify a default synthesized super call in the constructor
body, according to the structure that TypeScript emits.

ts.Program as a constructor parameter. This is not a lifecycle change, as
it was previously created with the ts.TypeChecker which is derived from the
ts.Program anyways. This change requires some reorganization in ngcc to
accommodate, especially in testing harnesses where DecorationAnalyzer is
created manually in a number of specs.

This refactoring moves code around between a few of the ngtsc subpackages,
with the goal of having a more logical package structure. Additional
interfaces are also introduced where they make sense.
The 'metadata' package formerly contained both the partial evaluator,
the TypeScriptReflectionHost as well as some other reflection functions,
and the Reference interface and various implementations. This package
was split into 3 parts.
The partial evaluator now has its own package 'partial_evaluator', and
exists behind an interface PartialEvaluator instead of a top-level
function. In the future this will be useful for reducing churn as the
partial evaluator becomes more complicated.
The TypeScriptReflectionHost and other miscellaneous functions have moved
into a new 'reflection' package. The former 'host' package which contained
the ReflectionHost interface and associated types was also merged into this
new 'reflection' package.
Finally, the Reference APIs were moved to the 'imports' package, which will
consolidate all import-related logic in ngtsc.

Previously the appendChild / removeChild could take null as an argument for
a child to be added / removed. This is difficult to understand since the
mentioned methods are noop if a child is null.
This commit clarifies the appendChild / removeChild signature to systematically
require a child node to be added removed. It turns out that null could be passed
only for a very specific i18n cases so now we guard a call to removeChild with
an explicit check on the i18n side.

On push builds, CircleCI provides `CIRCLE_COMPARE_URL`, which we use to
extract the commit range for a given build. When a workflow is rerun
(e.g. to recover from a flaked job), `CIRCLE_COMPARE_URL` is not
defined, causing some jobs to fail.
This commit fixes it by retrieving the compare URL from the original
workflow. It uses a slow process involving a (potentially large) number
of requests to CircleCI API.
It depends on the (undocumented) fact, that the `workspace_id` is the
same on all rerun workflows and the same as the original `workflow_id`.

test.sh is no longer needed... all the tests should now be executed via bazel.

Moving the tests over to CircleCI in pretty much "as-is" state just so that we can drop the dependency on Travis.
In the followup changes we plan to migrate these tests to run on sauce under bazel. @gregmagolan is working on that.
I've previously verified that all the tests executed in legacy-unit-tests-local already under bazel.
Therefore the legacy-unit-tests-local job is strictly not necessary any more, but given how flaky legacy-unit-tests-saucelabs is,
it is good to have the -local job just so that we can quickly determine if any failure is a flake or legit issue
(the bazel version of these tests could theoretically run in a slightly different way and fail or not fail in a different way, so having -lcoal job is just an extra safety check).

Fixes Ivy's `QueryList` not being an instance of the exported ViewEnginer `QueryList`.
Also reworks `first`, `last` and `length` to be regular properties, rather than setters. Reworking `length` was required to be able to extend the ViewEngine `QueryList`, but I reworked `first` and `last` as well since getters generate a lot more code when transpiled to ES5.
These changes fix FW-706.

* Currently the protractor utils assume that the specified Bazel server runfile can be resolved by just using the real file system. This is not the case on Windows because the runfiles are not symlinked into the working directory and need to be resolved through the runfile manifest.

Currently when building a package on Windows, the typings re-export for secondary entry-points is not valid TypeScript. Similarly the metadata and the "package.json" files use non-posix paths and cause inconsistency within the NPM package.
For example:
_package.json_
```
"esm5": "./esm5\\core.js",
"esm2015": "./esm2015\\core.js",
```
_testing.d.t.s_ (of the `core` package)
```
export * from './testing\testing';
```

`R3TestBed` allows consumers to configure a "testing module", declare components, override various metadata, etc. To do this, it implements its own JIT compilation, where components/directives/modules have Ivy definition fields generated based on testing metadata. It results in tests interfering with each other. One test might override something in a component that another test tries to use normally, causing failures.
In order to resolve this problem, we store current components/directives/modules defs before applying overrides and re-compiling. Once the test is complete, we restore initial defs, so the next tests interact with "clean" components.

Summary of changes:
- created .github/CODEOWNERS with docs and config similar to the one in .pullapprove.yml
- updated docs
- updated .github/angular-robot.yml to not expect pullapprove status
- removed .pullapprove.yml
The primary motivations behind this change are:
- CODEOWNERS didn't exist when we introduced pullapprove
- CODEOWNERS is a functionality tightly integrated with github which results in better DX
- pullapprove v2 has been very unstable recently causing productivity loss
- pullapprove v2 has been deprecated in favor of v3, which requires and migration

Previously, there could be identical template/listener function names
for a component's template, if it had multiple similarly structured
nested sub-templates or listeners.
This resulted in build errors:
`Identifier '<SOME_IDENTIFIER>' has already been declared`
This commit fixes this by ensuring that the template index is included
in the `contextName` passed to the `TemplateDefinitionBuilder`
responsible for processing nested sub-templates.
Similarly, the template or element index is included in the listener
names.

This PR assures that content projection works if an <ng-content> tag is
placed inside an <ng-template> in one component and that <ng-template>
is inserted into a different component. It fixes a bug where the

selector data instead of the declaration tree.

Prior to this change, ICU extraction logic was not taking into account nested bindings (that look like this: �0:1�) and only accounted for top level bindings (like this �0�). As a result, ICUs were not parsed and remained as text in the output. Now the extraction logic (regular expressions) take into account the nested bindings format as well.
