Currently, when running the ngcc binary directly and provide an invalid option ngcc will not error out and the user might have a hard time telling why ngcc is behaving not as expected.
With this change we now output an actionable error:
```
yarn ngcc --unknown-option
Options:
--version Show version number [boolean]
-s, --source A path (relative to the working directory)
of the `node_modules` folder to process.
[default: "./node_modules"]
-p, --properties An array of names of properties in
package.json to compile (e.g. `module` or
`es2015`)
Each of these properties should hold the
path to a bundle-format.
If provided, only the specified properties
are considered for processing.
If not provided, all the supported format
properties (e.g. fesm2015, fesm5, es2015,
esm2015, esm5, main, module) in the
package.json are considered. [array]
-t, --target A relative path (from the `source` path) to
a single entry-point to process (plus its
dependencies).
--first-only If specified then only the first matching
package.json property will be compiled.
[boolean]
--create-ivy-entry-points If specified then new `*_ivy_ngcc`
entry-points will be added to package.json
rather than modifying the ones in-place.
For this to work you need to have custom
resolution set up (e.g. in webpack) to look
for these new entry-points.
The Angular CLI does this already, so it is
safe to use this option if the project is
being built via the CLI. [boolean]
--legacy-message-ids Render `$localize` messages with legacy
format ids.
The default value is `true`. Only set this
to `false` if you do not want legacy
message ids to
be rendered. For example, if you are not
using legacy message ids in your
translation files
AND are not doing compile-time inlining of
translations, in which case the extra
message ids
would add unwanted size to the final source
bundle.
It is safe to leave this set to true if you
are doing compile-time inlining because the
extra
legacy message ids will all be stripped
during translation.
[boolean] [default: true]
--async Whether to compile asynchronously. This is
enabled by default as it allows
compilations to be parallelized.
Disabling asynchronous compilation may be
useful for debugging.
[boolean] [default: true]
-l, --loglevel The lowest severity logging message that
should be output.
[choices: "debug", "info", "warn", "error"]
--invalidate-entry-point-manifest If this is set then ngcc will not read an
entry-point manifest file from disk.
Instead it will walking the directory tree
as normal looking for entry-points, and
then write a new manifest file.
[boolean] [default: false]
--help Show help [boolean]
Unknown arguments: unknown-option, unknownOption

This commit adds support in the Angular monorepo and in the Angular
compiler(s) for TypeScript 3.8. All packages can now compile with
TS 3.8.
For most of the repo, only a handful few typings adjustments were needed:
* TS 3.8 has a new `CustomElementConstructor` DOM type, which enforces a
zero-argument constructor. The `NgElementConstructor` type previously
declared a required `injector` argument despite the fact that its
implementation allowed `injector` to be optional. The interface type was
updated to reflect the optionality of the argument.
* Certain error messages were changed, and expectations in tests were
updated as a result.
* tsserver (part of language server) now returns performance information in
responses, so test expectations were changed to only assert on the actual
body content of responses.
For compiler-cli and schematics (which use the TypeScript AST) a major
breaking change was the introduction of the export form:
```typescript
export * as foo from 'bar';
```
This is a `ts.NamespaceExport`, and the `exportClause` of a
`ts.ExportDeclaration` can now take this type as well as `ts.NamedExports`.
This broke a lot of places where `exportClause` was assumed to be
`ts.NamedExports`.
For the most part these breakages were in cases where it is not necessary
to handle the new `ts.NamedExports` anyway. ngtsc's design uses the
`ts.TypeChecker` APIs to understand syntax and so automatically supports the
new form of exports.
The View Engine compiler on the other hand extracts TS structures into
metadata.json files, and that format was not designed for namespaced
exports. As a result it will take a nontrivial amount of work if we want to
support such exports in View Engine. For now, these new exports are not
accounted for in metadata.json, and so using them in "folded" Angular
expressions will result in errors (probably claiming that the referenced
exported namespace doesn't exist).
Care was taken to only use TS APIs which are present in 3.7/3.6, as Angular
needs to remain compatible with these for the time being.
This commit does not update angular.io.

ng_update_migrations will still access the global yarn cache on its `ng update` call and there is no way to avoid this that I can see but if no other integration tests access the global yarn cache then that one test can have free reign over it.

This commit moves the build-related scripts
(`build-ivy-npm-packages.js`, `build-packages-dist.js` and
`package-builder.js`) to a dedicated directory to keep the `scripts/`
directory cleaner.
It also moves the logic for building the `zone.js` package to a separate
script, `zone-js-builder.js`, to make it re-usable. A subsequent commit
will use it to build the `zone.js` package when building the Ivy Angular
packages as well.

Because the WORKSPACE file is generated JIT by schematics in this integration test, we need to patch the schematics to add the work-around.
PR Close#35808
`ɵɵgetInheritedFactory()` is called from generated code for a component which extends another class. This function is detected by Closure to have a side effect and is not able to tree shake the component as a result. Marking it with `noSideEffects()` tells Closure it can remove this function under the relevant tree shaking conditions.

* it's tricky to get out of the runfiles tree with `bazel test` as `BUILD_WORKSPACE_DIRECTORY` is not set but I employed a trick to read the `DO_NOT_BUILD_HERE` file that is one level up from `execroot` and that contains the workspace directory. This is experimental and if `bazel test //:test.debug` fails than `bazel run` is still guaranteed to work as `BUILD_WORKSPACE_DIRECTORY` will be set in that context
* test //integration:bazel_test and //integration:bazel-schematics_test exclusively

* Skip all integration tests that are now handled by angular_integration_test except the tests that are tracked for payload size; these are:
- cli-hello-world*
- hello_world__closure
* add & pin @babel deps as newer versions of babel break //packages/localize/src/tools/test:test
@babel/core dep had to be pinned to 7.6.4 or else //packages/localize/src/tools/test:test failed. Also //packages/localize uses @babel/generator, @babel/template, @babel/traverse & @babel/types so these deps were added to package.json as they were not being hoisted anymore from @babel/core transitive.
NB: integration/hello_world__systemjs_umd test must run with systemjs 0.20.0
NB: systemjs must be at 0.18.10 for legacy saucelabs job to pass
NB: With Bazel 2.0, the glob for the files to test `"integration/bazel/**"` is empty if integation/bazel is in .bazelignore. This glob worked under these conditions with 1.1.0. I did not bother testing with 1.2.x as not having integration/bazel in .bazelignore is correct.

Before this change content queries with the `descendants: false` option, as implemented in ivy,
would not descendinto `<ng-container>` elements. This behaviour was different from the way the
View Engine worked. This change alligns ngIvy and VE behaviours when it comes to queries and the
`<ng-container>` elements and fixes a common bugs where a query target was placed inside the
`<ng-container>` element with a * directive on it.
Before:
```html
<needs-target>
<ng-container *ngIf="condition">
<div #target>...</div> <!-- this node would NOT match -->
</ng-container>
</needs-target>
```
After:
```html

Previously, we needed to manually specify a ChromeDriver version to
download on CI that would be compatible with the browser version
provided by the docker image used to run the tests. This was kept in the
`CI_CHROMEDRIVER_VERSION_ARG` environment variable.
With recent commits, we use the browser provided by `puppeteer` and can
determine the correct ChromeDriver version programmatically. Therefore,
we no longer need the `CI_CHROMEDRIVER_VERSION_ARG` environment
variable.
NOTE:
There is still one place (the `bazel-schematics` integration project)
where a hard-coded ChromeDriver version is necessary. Since I am not
sure what is the best way to refactor the tests to not rely on a
hard-coded version, I left it as a TODO for a follow-up PR.

Root cause is that for perf reasons we cache `LFrame` so that we don't have to allocate it all the time. To be extra fast we clear the `LFrame` on `enterView()` rather that on `leaveView()`. The implication of this strategy is that the deepest `LFrame` will retain objects until the `LFrame` allocation depth matches the deepest object.
The fix is to simply clear the `LFrame` on `leaveView()` rather then on `enterView()`

This means integration tests no longer need to depend on a $CI_CHROMEDRIVER_VERSION_ARG environment variable to specify which chromedriver version to download to match the locally installed chrome. This was bad DX and not having it specified was not reliable as webdriver-manager would not always download the chromedriver version to work with the locally installed chrome.
webdriver-manager update --gecko=false --standalone=false $CI_CHROMEDRIVER_VERSION_ARG is now replaced with node webdriver-manager-update.js in the root package.json, which checks which version of chrome puppeteer has come bundled with & downloads informs webdriver-manager to download the corresponding chrome driver version.
Integration tests now use "webdriver-manager": "file:../../node_modules/webdriver-manager" so they don't have to waste time calling webdriver-manager update in postinstall
"// resolutions": "Ensure a single version of webdriver-manager which comes from root node_modules that has already run webdriver-manager update",
"resolutions": {
"**/webdriver-manager": "file:../../node_modules/webdriver-manager"
}
This should speed up each integration postinstall by a few seconds.
Further, integration test package.json files link puppeteer via file:../../node_modules/puppeteer which is the ideal situation as the puppeteer post-install won't download chrome if it is already downloaded. In CI, since node_modules is cached it should not need to download Chrome either unless the node_modules cache is busted.
NB: each version of puppeteer comes bundles with a specific version of chrome. Root package.json & yarn.lock currently pull down puppeteer 2.1.0 which comes with chrome 80. See https://github.com/puppeteer/puppeteer#q-which-chromium-version-does-puppeteer-use for more info.
Only two references to CI_CHROMEDRIVER_VERSION_ARG left in integration tests at integration/bazel-schematics/test.sh which I'm not entirely sure how to get rid of it
Use a lightweight puppeteer=>chrome version mapping instead of launching chrome and calling browser.version()
Launching puppeteer headless chrome and calling browser.version() was a heavy-handed approach to determine the Chrome version. A small and easy to update mappings file is a better solution and it means that the `yarn install` step does not require chrome shared libs available on the system for its postinstall step
