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.

DEPRECATION:
Angular previously has supported an integration with the Web Tracing
Framework (WTF) for performance testing of Angular applications. This
integration has not been maintained and likely does not work for the
majority of Angular applications today. As a result, we are deprecating
the integration in Angular version 8.
This deprecation covers the following public APIs:
* `WtfScopeFn`
* `wtfCreateScope`
* `wtfStartTimeRange`
* `wtfEndTimeRange`
* `wtfLeave`

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.

There is an encoding issue with using delta `Δ`, where the browser will attempt to detect the file encoding if the character set is not explicitly declared on a `<script/>` tag, and Chrome will find the `Δ` character and decide it is window-1252 encoding, which misinterprets the `Δ` character to be some other character that is not a valid JS identifier character
So back to the frog eyes we go.

Previously, the processor that excludes certain cli commands
(`filterHiddenCommand`) was being run after the `createSitemap`
processor, resulting in those commands to be present in `sitemap.xml`,
while the actual pages where missing. This also resulted in 404s, when
search engine crawlers tried to index the missing URLs.
This commit fixes it by ensuring that the `filterHiddenCommand`
processor is run before the `createSitemap` processor.

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.).

This minimises the risk of unexpected failures due to breaking changes,
when building a new image (e.g. as a result of an unrelated config
change in Dockerfile).
PR Close#29976
Previously, the preview server docker image was based on Debian 8
(jessie). Recently, `jessie-updates` and `jessie-backborts` were removed
from the Debian mirrors ([more info][1]), thus breaking new builds of
the image.
Instead of updating `/etc/apt/sources.list` to remove the obsolete
sources, this commit upgrades to Debian 9 (stretch).
(The GCE VM running the preview server docker container was also
upgraded from Debian 8 to 9 this morning.)
---
Other changes:
- Removed dependency on `chkconfig`, which is not supported on Debian 9.
- Installing `nginx` from the regular repositories (instead of
`*-backports).
- Upgraded to `pm2` v3, which can handle hooking itself up to system
startup better (without `chkconfig` - see above).
- Updated tests to reflect the fact that `nginx` has dropped the reason
phrase in response status lines for HTTP/2 (in compliance with
[the spec][2]). (HTTP/1.1: `HTTP/1.1 200 OK` | HTTP/2: `HTTP/2 200`)

In #29926, the size of the build artifacts has increased due to turning
on differential loading (which generates an es2015/es5 pair for each JS
resource).
To avoid the preview server's rejecting the build artifacts (as in
[288181][1]), this commit increases the max allowed artifact size from
20MB to 25MB (current artifact size after #29926 is ~22MB).

In light of #29926, that will change the path of `tsconfig.app.json`,
this commit switches from a hard-coded `tsconfig.app.json` path to
looking it up in `angular.json` (to be more future-proof).
PR Close#29989
Previously, the `build-with-ivy` script could be used to build the `aio`
project with Ivy (once it had been prepared with `ivy-ngcc`, etc.) and
then restored the configuration (e.g. `tsconfig.json`) to non-ivy mode.
As a result, it was not useful for running other commands (e.g. unit/e2e
tests) in Ivy mode.
This commit renames the script to `switch-to-ivy` and employs a
different model (similar to `ng-packages-installer`), where the project
is setup to run in Ivy mode and then all subsequent commands are
executed in that mode (until restored).
Since this is currently only used on CI, there is no automatic way to
switch back to non-ivy mode (but it could be implemented in the future
if needed).
Finally, the script now modifies `src/tsconfig.app/json` instead of
`tsconfig.json` to ensure that the `angularCompilerOptions` are not
ignored/overwritten. This is also closer to what the cli generates
with the `--enable-ivy` option.

The server used for testing on localhost has less optimizations (e.g.
serves uncompressed files), so we need to wait longer the ServiceWorker
to be loaded and registered to allow Lighthouse to reliably detect it,

Now, one can add an `@alias` tag to API docs, which tells dgeni that this
API element (usually a `const`) is really just an alias for some API element
defined elsewhere.
Dgeni will then look up this API element and copy over the properties from
the alias to the current doc.
For example, we would like to privately export an Enum from `@angular/core`
but then publicly export this from `@angular/common`:
**packages/core/private_exports.ts**
```ts
/**
* Description of this document.
*/
export enum ɵSomeEnum { ... }
```
**packages/common/public_api.ts**
```ts
import {ɵSomeEnum} from '@angular/core';
/**
* @alias core/ɵSomeEnum
*/
export const SomeEnum = ɵSomeEnum;
```
In the generated docs there will be a page for `common/SomeEnum`, which
will be rendered as an enum, rather than a const, showing the description
extracted from the `core/ɵSomeEnum`.
---
The implementation of this feature required some refactoring of the other
processing:
1. Previously `ɵ` prefixed exports were not even considered.
2. Due to 1. some processors needed to have guards added to ignore such
private exports (`addMetadataAliases` and `checkContentRules`).
3. The processing of package pages had to be reworked (and split) so that
it picked up the aliased export docs after their alias proeprties had
been copied.
