Previously, we would simply prepend any relative URL with the HREF
for the current route (pulled from document.location). However,
this does not correctly account for the leading slash URLs that
would otherwise be parsed correctly in the browser, or the
presence of a base HREF in the DOM.
Therefore, we use the built-in URL implementation for NodeJS,
which implements the WHATWG standard that's used in the browser.
We also pull the base HREF from the DOM, falling back on the full
HREF as the browser would, to form the correct request URL.

Keen and I were talking about what it would take to support getting
references at a position in the current language service, since it's
unclear when more investment in the Ivy LS will be available. Getting TS
references from a template is trivial -- we simply need to get the
definition of a symbol, which is already handled by the language
service, and ask the TS language service to give us the references for
that definition.
This doesn't handle references in templates, but that could be done in a
subsequent pass.

Fixes#20402
PR Close#37301
This PR provides a more helpful error than the one currently present:
`el.setAttribute is not a function`. It is not valid to have directives with host bindings
on `ng-template` or `ng-container` nodes. VE would silently ignore this, while Ivy
attempts to set the attribute and throws an error because these are comment nodes
and do not have `setAttribute` functionality.
It is better to throw a helpful error than to silently ignore this because
putting a directive with host binding on an `ng-template` or `ng-container` is most often a mistake.
Developers should be made aware that the host binding will have no effect in these cases.
Note that an error is already thrown in Ivy, as mentioned above, so this
is not a breaking change and can be merged to both master and patch.

This commit removes all markers from the inline template in
`AppComponent` and external template in `TemplateReference`.
Test scenarios should be colocated with the test cases themselves.
Besides, many existing cases are invalid. For example, if we want to
test autocomplete for HTML element, the existing test case is like:
```
<~{cursor} h1>
```
This doesn't make much sense, becasue the language service already sees
the `h1` tag in the template. The correct test case should be:
```
<~{cursor
```
IMO, this reflects the real-world use case better.
This commit also uncovers a bug in the way HTML entities autocompletion
is done. There's an off-by-one error in which a cursor that immediately
trails the ampersand character fails to trigger HTML entities
autocompletion.

**Problem**
After #31109 and #31865, it's still possible to get locked in state
`EXISTING_CLIENTS_ONLY`, without any possibility to get out (even by
pushing new updates on the server).
More specifically, if control doc `/latest` of `ngsw:/:db:control` once
gets a bad value, then the service worker will fail early, and won't be
able to overwrite `/latest` with new, valid values (the ones from future
updates).
For example, once in this state, URL `/ngsw/state` will show:
NGSW Debug Info:
Driver state: EXISTING_CLIENTS_ONLY (Degraded due to failed initialization: Invariant violated (initialize): latest hash 8b75… has no known manifest
Error: Invariant violated (initialize): latest hash 8b75… has no known manifest
at Driver.<anonymous> (https://my.app/ngsw-worker.js:2302:27)
at Generator.next (<anonymous>)
at fulfilled (https://my.app/ngsw-worker.js:175:62))
Latest manifest hash: 8b75…
Last update check: 22s971u
... with hash `8b75…` corresponding to no installed version.
**Solution**
Currently, when such a case happens, the service worker [simply fails
with an assertion][1]. Because this failure happens early, and is not
handled, the service worker is not able to update `/latest` to new
installed app versions.
I propose to detect this corrupted case (a `latest` hash that doesn't
match any installed version) a few lines above, so that the service
worker can correctly call its [already existing cleaning code][2].

Previously, event listeners for component output events attached on an
Angular custom element before inserting it into the DOM (i.e. before
instantiating the underlying component) didn't fire for events emitted
during initialization lifecycle hooks, such as `ngAfterContentInit`,
`ngAfterViewInit`, `ngOnChanges` (initial call) and `ngOnInit`.
The reason was that that `NgElementImpl` [subscribed to events][1]
_after_ calling [ngElementStrategy#connect()][2], which is where the
[initial change detection][3] takes place (running the initialization
lifecycle hooks).
This commit fixes this by:
1. Ensuring `ComponentNgElementStrategy#events` is defined and available
for subscribing to, even before instantiating the component.
2. Ensuring `NgElementImpl` subscribes to `NgElementStrategy#events`
before calling `NgElementStrategy#connect()` (which initializes the
component instance).

of addressing PR review feedback. Right now, always the empty

it as the already-requested API value. This is not the case as
the default promise is also truthy. We should just fix this by making

This finder is designed to only process entry-points that are reachable
by the program defined by a tsconfig.json file.
It is triggered by calling `mainNgcc()` with the `findEntryPointsFromTsConfigProgram`
option set to true. It is ignored if a `targetEntryPointPath` has been
provided as well.
It is triggered from the command line by adding the `--use-program-dependencies`
option, which is also ignored if the `--target` option has been provided.
Using this option can speed up processing in cases where there is a large
number of dependencies installed but only a small proportion of the
entry-points are actually imported into the application.

Also this commit should speed up processing: Previously we were parsing

The angular.io production deployment script (`deploy-to-firebase.sh`)
compares the major version corresponding to the current branch (e.g.
`8` for branch `8.1.x`) against the major stable version (e.g. `9` if
the current stable version is `9.1.0`). It then uses the result of that
comparison to determine whether the current branch corresponds to a
newer version than stable (i.e. an RC version) and thus should not be
deployed or to an older version and thus may need to be deployed to an
archive vX.angular.io project.
Previously, the script was using string comparison (`<`) to compare the
two major versions. This could produce incorrect results for an RC major
version that is numerically greater than the stable but
lexicographically smaller. For example, 10 vs 9 (10 is numerically
greater but lexicographically smaller than 9).
Example of a CI job that incorrectly tried to deploy an RC branch to
production: https://circleci.com/gh/angular/angular/726414
This commit fixes it by switching to an integer comparison (i.e. using

`NgCompiler` is the heart of ngtsc and can be used to analyze and compile
Angular programs in a variety of environments. Most of these integrations
rely on `NgProgram` and the creation of an `NgCompilerHost` in order to
create a `ts.Program` with the right shape for `NgCompiler`.
However, certain environments (such as the Angular Language Service) have
their own mechanisms for creating `ts.Program`s that don't make use of a
`ts.CompilerHost`. In such environments, an `NgCompilerHost` does not make
sense.
This commit breaks the dependency of `NgCompiler` on `NgCompilerHost` and
extracts the specific interface of the host on which `NgCompiler` depends
into a new interface, `NgCompilerAdapter`. This interface includes methods
from `ts.CompilerHost`, the `ExtendedTsCompilerHost`, as well as APIs from
`NgCompilerHost`.
A consumer such as the language service can implement this API without
needing to jump through hoops to create an `NgCompilerHost` implementation
that somehow wraps its specific environment.
PR Close#37118
When the compiler encounters a function call within an NgModule imports
section, it attempts to resolve it to an NgModule-annotated class by
looking at the function body and evaluating the statements there. This
evaluation can only understand simple functions which have a single
return statement as their body. If the function the user writes is more
complex than that, the compiler won't be able to understand it and
previously the PartialEvaluator would return a "DynamicValue" for
that import.
With this change, in the event the function body resolution fails the
PartialEvaluator will now attempt to use its foreign function resolvers to
determine the correct result from the function's type signtaure instead. If
the function is annotated with a correct ModuleWithProviders type, the
compiler will be able to understand the import without static analysis of
the function body.

If we detect that an injectable class is inheriting from another injectable, we generate code that looks something like this:
```
const baseFactory = ɵɵgetInheritedFactory(Child);
@Injectable()
class Parent {}
@Injectable()
class Child extends Parent {
static ɵfac = (t) => baseFactory(t || Child)
}
```
This usually works fine, because the `ɵɵgetInheritedFactory` resolves to the factory of `Parent`, but the logic can break down if the `Child` class has a custom decorator. Custom decorators can return a new class that extends the original once, which means that the `ɵɵgetInheritedFactory` call will now resolve to the factory of the `Child`, causing an infinite loop.
These changes fix the issue by changing the inherited factory resolution logic so that it walks up the prototype chain class-by-class, while skipping classes that have the same factory as the class that was passed in.
