Maximilian Koeller ee35e223a7 feat(service-worker): use `ignoreVary: true` when retrieving responses from cache (#34663)
The Angular ServiceWorker always uses a copy of the request without
headers for caching assets (in order to avoid issues with opaque
responses). Therefore, it was previously not possible to retrieve
resources from the cache if the response contained [Vary](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary) headers.

In addition to that, `Vary` headers do not work in all browsers (or work
differently) and may not work as intended with ServiceWorker caches. See
[this article](https://www.smashingmagazine.com/2017/11/understanding-vary-header) and the linked resources for more info.

This commit avoids the aforementioned issues by making sure the Angular
ServiceWorker always sets the `ignoreVary` option passed to
[Cache#match()](https://developer.mozilla.org/en-US/docs/Web/API/Cache/match) to `true`. This allows the ServiceWorker to correctly
retrieve cached responses with `Vary` headers, which was previously not
possible.

Fixes #36638

BREAKING CHANGE:

Previously, [Vary](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Vary)
headers would be taken into account when retrieving resources from the
cache, completely preventing the retrieval of cached assets (due to
ServiceWorker implementation details) and leading to unpredictable
behavior due to inconsistent/buggy implementations in different
browsers.

Now, `Vary` headers are ignored when retrieving resources from the
ServiceWorker caches, which can result in resources being retrieved even
when their headers are different. If your application needs to
differentiate its responses based on request headers, please make sure
the Angular ServiceWorker is [configured](https://angular.io/guide/service-worker-config)
to avoid caching the affected resources.

Maximilian Koeller dc9f4b994e feat(service-worker): include `CacheQueryOptions` options in ngsw-config (#34663)
Previously it was not possible to provide `CacheQueryOptions` ([MDN](https://developer.mozilla.org/en-US/docs/Web/API/Cache)) for querying the Cache.
This commit introduces a new parameter called `cacheQueryOptions` for `DataGroup` and `AssetGroup`.
Currently only `ignoreSearch` is supported as `ignoreVary` and `ignoreMethod` would require using
the complete Request object for matching which is not possible with the current implementation.

Closes #28443

1. We were serving es2017 code during tests. I've set it to es5.

Paul Gschwendtner 5615928df9 build: no longer run tslint from within gulp task (#35800)
Switches our tslint setup to the standard `tslint.json` linter excludes.
The set of files that need to be linted is specified through a Yarn script.

For IDEs, open files are linted with the closest tslint configuration, if the
tslint IDE extension is set up, and the source file is not excluded.

We cannot use the language service plugin for tslint as we have multiple nested
tsconfig files, and we don't want to add the plugin to each tsconfig. We
could reduce that bloat by just extending from a top-level tsconfig that
defines the language service plugin, but unfortunately the tslint plugin does
not allow the use of tslint configs which are not part of the tsconfig project.

This is problematic since the tslint configuration is at the project root, and we
don't want to copy tslint configurations next to each tsconfig file.

Additionally, linting of `d.ts` files has been re-enabled. This has been
disabled in the past and a TODO has been left. This commit fixes the
lint issues and re-enables linting.

George Kalpakas 094538c0ce feat(service-worker): recover from `EXISTING_CLIENTS_ONLY` mode when there is a valid update (#31865)
Previously, when the ServiceWorker entered a degraded mode
(`EXISTING_CLIENTS_ONLY` or `SAFE_MODE`) it would remain in that mode
for the rest of the lifetime of ServiceWorker instance. Note that
ServiceWorkers are stopped by the browser after a certain period of
inactivity and a new instance is created as soon as the ServiceWorker
needs to handle an event (such as a request from the page). Those new
instances would start from the `NORMAL` mode.

The reason for this behavior is to err on the side of caution: If we
can't be sure why the ServiceWorker entered the degraded mode, it is
risky to try recovering on the same instance and might lead to
unexpected behavior.

However, it turns out that the `EXISTING_CLIENTS_ONLY` mode can only be
a result of some error happening with the latest version (e.g. a hash
mismatch in the manifest). Therefore, it is safe to recover from that
mode once a new, valid update is successfully installed and to start
accepting new clients.

This commit ensures that the mode is set back to `NORMAL`, when (a) an
update is successfully installed and (b) the current mode is
`EXISTING_CLIENTS_ONLY`.

Besides making the behavior more predictable (instead of relying on the
browser to decide when to terminate the current ServiceWorker instance
and create a new one), this change can also improve the developer
experience:
When people notice the error during debugging and fix it by deploying a
new version (either to production or locally), it is confusing that the
ServiceWorker will fetch and install the update (as seen by the requests
in the Network panel in DevTools) but not serve it to clients. With this
change, the update will be served to new clients as soon as it is
installed.

George Kalpakas bda2b4ebb6 fix(service-worker): keep serving clients on older versions if latest is invalidated (#31865)
Previously, when the latest version was invalidated (e.g. due to a hash
mismatch), the SW entered a degraded `EXISTING_CLIENTS_ONLY` mode and
removed _all_ clients from its client-version map (essentially stopping
to serve any clients). Based on the code and surrounding comments, the
intention seems to have been to only remove clients that were on the
invalidated version, but keep other clients on older versions.

This commit fixes it by only unassigning clients what were on the latest
version and keep clients assigned to older versions.

Previously, (presummably due to a typo) the `okToCacheOpaque` argument

This commit doesn't change the behavior wrt caching, but it makes it
more explicit that only non-timed-out responses are cached. In case of a

have cached it anyway, but this makes change makes it more explicit (and
more similar to the equivalent part in [handleFetchWithFreshness()][1]).

George Kalpakas 5306330d85 test(service-worker): better simulate opaque requests (#30977)
Previously, opaque responses where handled a little differently than
other responses from the mock server. More specifically, they were not
tracked (so no assertions could be made for them) and their
[`Body` mixin][1] methods (such as `arrayBuffer()`, `json()`, `text()`)
would throw an error due to `body` being `null`.

This commit ensures opaque responses are also captured on the mock
server and also changes `Body` mixin methods to better simulate the
[spec'd behavior][2].

(These improvements will be necessary to test caching of opaque
responses in a subsequent commit.)
