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.

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.

Helper functions for making navigation requests were created in several

The `latest` argument was only ever set to the value of comparing
`this.latestHash` with the `appVersion` hash, which is already computed
inside `versionFailed()`, so there is no reason to pass it as an
argument as well.
This doesn't have any impact on the current behavior of the SW.

Previously the template compiler would generate the same jsdoc comment
block for `$localize` as for `goog.getMsg()`. But it turns out that
the closure compiler will complain if the `@desc` and `@meaning`
tags are used for non-`getMsg()` calls.
For now we do not generate the comments for `$localize` calls. They are
not being used at the moment.
In the future it would be good to be able to extract the descriptions and
meanings from the `$localize` calls rather than relying upon the `getMsg()`
calls, which we do now. So we need to find a workaround for this constraint.

Prior to this fix if a `NO_CHANGE` value was assigned to a binding, or
an interpolation value rendererd a `NO_CHANGE` value, then the presence
of that value would cause the internal counter index values to not
increment properly. This patch ensures that this doesn't happen and
that the counter/bitmask values update accordingly.

This is a prerequisite to fix a bug in template completions whereby
completion of the string `ti` for the variable `title` results in
`tititle`.
This is because the position where the completion is requested is used
to insert the completion text. This is incorrect. Instead, a
`replacementSpan` should be used to indicate the span of text that needs
to be replaced. Angular's own `Completion` interface is insufficient to
hold this information. Instead, we should just use ts.CompletionEntry.
Also added string enum for `CompletionKind`, which is similar to
ts.ScriptElementKind but contains more info about HTML entities.

Mutable exports, i.e. using this pattern

working on banning it google internal codebase.
The workaround is adding an explcit getter function.

This test uses localization in the `AppComponent` component:
* an `i18n` attribute in the template
* a call to the `$localize` tag in the component constructor
PR Close#31609
This commit changes the Angular compiler (ivy-only) to generate `$localize`
tagged strings for component templates that use `i18n` attributes.
BREAKING CHANGE
Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.
```ts
import '@angular/localize';
```
For non-CLI applications this could be added as a script to the index.html
file or another suitable script file.

DebugElement.query also searches elements that may have been created
outside of Angular (ex: with `document.appendChild`). The current
behavior attempts to get the LContext of these nodes but throws an error
because the LContext does not exist.

This allows the script to recognise some matches that it would miss
before and avoid listing them as missing.
Ideally, the script should be able to understand the globs in
`CODEOWNERS` and correctly find matching file-system paths.However, for
the limited purposes of the script (and for just a couple of relevant
globs), implementing this would be an overkill.
Implemented the "manual expansion" instead.
(We might revisit, if the needs change.)

Commit 904a2018e0 introduced a new migration for
undecorated classes with decorated Angular class members. Currently the migration
always calls `tree.beginUpdate` and `tree.commitUpdate` (even if there are no changes).
This causes unnecessary updates to be reported to developers running `ng update`. Once
an update is commited, the CLI will report the update regardless of whether any changes were
made or not.
This behavior can be observed in the `ng_update_migrations` integration test. See:
https://circleci.com/gh/angular/angular/438470#tests/containers/3. Notice how all
source files are denoted as `UPDATED` (even though there are no changes).

`simple-server.js` is vulnerable to a trivial path traversal attack, i.e. an
attacker can supply a path like `../../etc/passwd` to read arbitrary files on
the server. This change fixes the issue by properly resolving the path, and then
only serving files under the current directory (as intended).
This is not really a security issue, given the code is not part of Angular, but
rather just testing infrastructure for Angular itself, and the CI servers are
not expected to contain confidential information, but still worth fixing for
code hygiene.
