Misko Hevery 47bcb5bc35 build(core): add bazel test targets for core (#21053)
- Add tests target for `test`, `test_node_only` and `test_web` in `core` package.
- Created a `_testing_init` pseudo package where bootstrap code for tests is kept.
- Moved `source_map_util` from `test` to `testing` so to prevent circular dependency.
- Removed `visibility:public` for testing `BUILD` packages.

Alex Rickabaugh 20e1cc049f fix(service-worker): check for updates on navigation
Currently the Service Worker checks for updates only on SW startup,
an event which happens frequently but also nondeterministically. This
makes it hard for developers to observe the update process or reason
about how updates will be delivered to users. This problem is
exacerbated by the DevTools behavior of keeping the SW alive
indefinitely while opened, effectively preventing the page from
updating at all.

This change causes the SW to additionally check for updates on
navigation requests (app page reloads). This creates deterministic
update behavior, and is much easier for developers to reason about.
It does leave the old update-on-SW-startup behavior in place, as
removing that would be a breaking change.

Alex Eagle ef534c0cc1 build: upgrade bazel rules to latest (#20768)
Add enough BUILD files to make it possible to
`bazel build packages/core/test`

Also re-format BUILD.bazel files with Buildifier.
Add a CI lint check that they stay formatted.

Alex Rickabaugh f582620d5b fix(service-worker): use relative path for ngsw.json
Not every application is served from the domain root. The Service
Worker made a bad assumption that it would be, and so requested
/ngsw.json from the domain root.

This change corrects this assumption, and requests ngsw.json without
the leading slash. This causes the request to be interpreted
relative to the SW origin, which will be the application root.

Alex Rickabaugh 3bcf0cf472 fix(service-worker): PushEvent.data has to be decoded (#19764)
PushEvent.data is not the data object itself, but an instance representing
the data in wire format, with methods to synchronously decode it to JSON,
ArrayBuffer, etc. NGSW assumes all push data is in JSON format.

Alex Rickabaugh 396c2417d9 fix(service-worker): freshness strategy should clone response for cache (#19764)
When Cache.put() is called with a Response, it consumes the response. If
the Response is used for any other purpose (such as satisfying the
original FetchEvent) it must be cloned first.

A bug exists in the mocks used for SW tests, where this condition is not
validated. The bodies of MockResponses can be utilized repeatedly without
erroring in the same way that a real browser would. This bug is fixed by
this commit, which causes tests for the freshness strategy of data caching
to start failing.

The cause of this failure is a second bug in the data caching code, where
the Response is not cloned prior to being passed to Cache.put(). This is
also fixed.

Alex Rickabaugh f10f8db5fb fix(service-worker): several misc fixes for corner cases
This commit fixes several issues discovered through use in real apps.

* The sha1() function operated on text content, causing issues for binary-format files.
  A sha1Binary() function which operates on unparsed data now avoids any encoding issues.
* The characters '?' and '+' were not escaped in Glob-to-regex conversion previously, but
  are now.
* URLs from the browser contain the full origin, but were checked against the table of
  hashes from the manifest which only has the path for URLs from the same origin. Now the
  origin is checked and URLs are relativized to the domain root before comparison if
  appropriate.
* ngsw: prefix was missing from data groups, is now added.
* Occasionally servers will return a redirected response for an asset, and caching it could
  cause errors for navigation requests. The SW now handles this by detecting such responses
  and following the redirect manually, to avoid caching a redirected response.
* The request for known assets is now created from scratch from the URL before fetching from
  the network, in order to sanitize it and avoid carrying any special modes or headers that
  might result in opaque responses.
* Debugging log for troubleshooting.
* Avoid creating errors by returning 504 responses on error.
* Fix bug where idle queue doesn't run in some circumstances.
* Add tests for the above.

Alex Rickabaugh d442b6855f feat(service-worker): introduce the @angular/service-worker package (#19274)
This service worker is a conceptual derivative of the existing @angular/service-worker maintained at github.com/angular/mobile-toolkit, but has been rewritten to support use across a much wider variety of applications.

Entrypoints include:

@angular/service-worker: a library for use within Angular client apps to communicate with the service worker.
@angular/service-worker/gen: a library for generating ngsw.json files from glob-based SW config files.
@angular/service-worker/ngsw-worker.js: the bundled service worker script itself.
@angular/service-worker/ngsw-cli.js: a CLI tool for generating ngsw.json files from glob-based SW config files.
