As of TypeScript 3.9, the tsc emit is not compatible with Closure
Compiler due to
https://github.com/microsoft/TypeScript/pull/32011.
There is some hope that this will be fixed by a solution like the one
proposed in
https://github.com/microsoft/TypeScript/issues/38374 but currently it's
unclear if / when that will
happen.
Since the Closure support has been somewhat already broken, and the
tsickle pass has been a source
of headaches for some time for Angular packages, we are removing it for
now while we rethink our
strategy to make Angular Closure compatible outside of Google.
This change has no effect on our Closure compatibility within Google
which work well because all the
code is compiled from sources and passed through tsickle.
This change only disables the tsickle pass but doesn't remove it.
A follow up PR should either remove all the traces of tscikle or
re-enable the fixed version.
BREAKING CHANGE: Angular npm packages no longer contain jsdoc comments
to support Closure Compiler's advanced optimizations
The support for Closure compiler in Angular packages has been
experimental and broken for quite some
time.
As of TS3.9 Closure is unusable with the JavaScript emit. Please follow
https://github.com/microsoft/TypeScript/issues/38374 for more
information and updates.
If you used Closure compiler with Angular in the past, you will likely
be better off consuming
Angular packages built from sources directly rather than consuming the
version we publish on npm
which is primarily optimized for Webpack/Rollup + Terser build pipeline.
As a temporary workaround you might consider using your current build
pipeline with Closure flag
`--compilation_level=SIMPLE`. This flag will ensure that your build
pipeline produces buildable and
runnable artifacts, at the cost of increased payload size due to
advanced optimizations being disabled.
If you were affected by this change, please help us understand your
needs by leaving a comment on https://github.com/angular/angular/issues/37234.

* 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
* run "exclusive" and "manual" bazel-in-bazel integration tests in their own CI job as they take 8m+ to execute
```
//integration:bazel-schematics_test PASSED in 317.2s
//integration:bazel_test PASSED in 167.8s
```
* 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.

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

In #33046, internal uses of `zone.js` were switched to reference it
directly from source (built with Bazel) instead of npm. As a result, the
necessary scripts were updated to build `zone.js` as necessary. However,
some `integration/**/debug-test.sh` scripts were missed (apparently
because they are not used on CI, but only locally as helpers for
debugging the integration projects).
This commit updates the `scripts/build-packages-dist.sh` script to also
build `zone.js`, so that other scripts (such as the various
`debug-test.sh` scripts) can use it.

Bundle size changed in both zone.js(legacy) and zone-evergreen.js
- zone.js(legacy) package increased a little because the following feature and fixes.
1. #31699, handle MSPointer events PR
2. https://github.com/angular/zone.js/pull/1219 to add __zone_symbol__ customization support
- zone-evergreen.js package decreased because
1. the MSPointer PR only for legacy
2. the Object.defineProperty patch is moved to legacy #31660

Updates the NodeJS version to the latest stable version at the time of
writing (v10.16.0). We need to update our image to use a minimum NodeJS
version of v10.15.0 because new CLI apps automatically install a non-locked
version of selenium-webdriver that now requires NodeJS >= 10.15.0 since the
latest release of 17th June 2019 (4.0.0-alpha.3).
