Testing of Ivy revealed two bugs in the AstMemoryEfficientTransformer
class, a part of existing View Engine compiler infrastructure that's
reused in Ivy. These bugs cause AST expressions not to be transformed
under certain circumstances.
The fix is simple, and tests are added to ensure the specific expression
forms that trigger the issue compile properly under Ivy.

While marking a given views tree as dirty we should go all the way to the
root of the views tree and cross boundaries of dynamically inserted views.
In other words the markForCheck functionality should consider parents of
dynamically inserted views.

Prior to this change we used current injector implementation for module injector, which was causing problems and produces circular dependencies in case the same token is referenced (with @SkipSelf flag) in the `deps` array. The origin of the problem was that once `directiveInject` implementation becomes active, it was used for module injector as well, thus searching deps in Component/Directive DI scope. This fix sets `injectInjectorOnly` implementation for module injector to resolve the problem.

The web_worker images example is currently not really usable
because the rendered button that can be used to upload
an "image" to the demo is currently not working. This is because
the HTML markup for the `file-field` is not matching what `materialize-css`
expects. See: https://materializecss.com/text-inputs.html

Currently all playground examples are built with NGC, and most
of the HTML resources are automatically inlined. Surprisingly NGC
is able to resolve the relative component assets even though these
aren't specified in the `assets`. This seems to work because NGC
resolves the files in the execroot where the files are present
(if Bazel doesn't use sandboxing).

The `web_workers/images` example is not being tested by any e2e
spec and therefore it's technically not necessary to fix that it uses
external resources, though in order to ensure that the Bazel builds
are hermetic and that we can eventually add e2e specs for the
web_worker/image example, we should avoid any use of external
resources.
We remove the `web-animations` polyfill in the `web_workers/animations`
example because we should try to vendor as few as possible deps. Also
the animations API is already supported by browsers we run the e2e tests
against (note here: `web_workers/animations` is currently also disabled)

Prior to this update we had separate contentQueries and contentQueriesRefresh functions to handle creation and update phases. This approach was inconsistent with View Queries, Host Bindings and Template functions that we generate for Component/Directive defs. Now the mentioned 2 functions are combines into one (contentQueries), creation and update logic is separated with RenderFlags (similar to what we have in other generated functions).

For TypeScript compilation units that have the "strictFunctionTypes"
option enabled, an error would be produced for Ivy's definition fields
in declaration files in the case of inheritance across directives or
pipes.
This change loosens the definition types to allow for subtypes of the
defined type where necessary.
A test package that has the "strict" option enabled verifies that we
won't regress in environments where strict type checking is enabled.

With #28594 we refactored the `@angular/compiler` slightly to
allow opting out from external symbol re-exports which are
enabled by default.
Since symbol re-exports only benefit projects which have a
very strict dependency enforcement, external symbols should
not be re-exported by default as this could grow the size of
factory files and cause unexpected behavior with Angular's
AOT symbol resolving (e.g. see: #25644).
Note that the common strict dependency enforcement for source
files does still work with external symbol re-exports disabled,
but there are also strict dependency checks that enforce strict
module dependencies also for _generated files_ (such as the
ngfactory files). This is how Google3 manages it's dependencies
and therefore external symbol re-exports need to be enabled within
Google3.
Also "ngtsc" also does not provide any way of using external symbol
re-exports, so this means that with this change, NGC can partially
match the behavior of "ngtsc" then (unless explicitly opted-out).
As mentioned before, internally at Google symbol re-exports need to
be still enabled, so the `ng_module` Bazel rule will enable the symbol
re-exports by default when running within Blaze.
Fixes#25644.

Previously, using a pipe in an input binding on an ng-template would
evaluate the pipe in the context of node that was processed before the
template. This caused the retrieval of e.g. ChangeDetectorRef to be
incorrect, resulting in one of the following bugs depending on the
template's structure:
1. If the template was at the root of a view, the previously processed
node would be the component's host node outside of the current view.
Accessing that node in the context of the current view results in a crash.
2. For templates not at the root, the ChangeDetectorRef injected into the
pipe would correspond with the previously processed node. If that node
hosts a component, the ChangeDetectorRef would not correspond with the
view that the ng-template is part of.
The solution to the above problem is two-fold:
1. Template compilation is adjusted such that the template instruction
is emitted before any instructions produced by input bindings, such as
pipes. This ensures that pipes are evaluated in the context of the
template's container node.
2. A ChangeDetectorRef can be requested for container nodes.

During analysis, the `ComponentDecoratorHandler` passes the component
template to the `parseTemplate()` function. Previously, there was little or
no information about the original source file, where the template is found,
passed when calling this function.
Now, we correctly compute the URL of the source of the template, both
for external `templateUrl` and in-line `template` cases. Further in the
in-line template case we compute the character range of the template
in its containing source file; *but only in the case that the template is
a simple string literal*. If the template is actually a dynamic value like
an interpolated string or a function call, then we do not try to add the
originating source file information.
The translator that converts Ivy AST nodes to TypeScript now adds these
template specific source mappings, which account for the file where
the template was found, to the templates to support stepping through the
template creation and update code when debugging an Angular application.
Note that some versions of TypeScript have a bug which means they cannot
support external template source-maps. We check for this via the
`canSourceMapExternalTemplates()` helper function and avoid trying to
add template mappings to external templates if not supported.

When template bindings are being parsed the event handlers
were receiving a source span that included the whole attribute.
Now they get a span that is focussed on the handler itself.
PR Close#28055
The `convertActionBinding()` now accepts an optional `baseSourceSpan`,
which is the start point of the action expression being converted in the
original source code. This is used to compute the original position of
the output AST nodes.

When tokenizing markup (e.g. HTML) element attributes
can have quoted or unquoted values (e.g. `a=b` or `a="b"`).
The `ATTR_VALUE` tokens were capturing the quotes, which
was inconsistent and also affected source-mapping.
Now the tokenizer captures additional `ATTR_QUOTE` tokens,
which the HTML related parsers understand and factor into their
token parsing.

There are some differences in how ivy maps template source
compared to View Engine. In this commit we recreate the View Engine
tests for ivy.
PR Close#28055
Previously the call to `extractSourceMap()` would only work if the
`//#sourceMappingURL ...` was the last line of the file. This doesn't
work if the code is JIT evaluated as the comment is actually the last
line in the body of a function, wrapped by curly-braces.
PR Close#28055
When testing JIT code, it is useful to be able to access the
generated JIT source. Previously this is done by spying on the
global `Function` object, to capture the code when it is being
evaluated. This is problematic because you can only capture
the body of the function, and not the arguments, which messes
up line and column positions for source mapping for instance.
Now the code that generates and then evaluates JIT code is
wrapped in a `JitEvaluator` class, making it possible to provide
a mock implementation that can capture the generated source of
the function passed to `executeFunction(fn: Function, args: any[])`.
PR Close#28055
When we resolve a component `templateUrl` we copy the contents of the
resolved template file into the `template` property.
Previously we would then remove the `templateUrl` to indicate that
the component has been resolved. But this meant that we no longer had
access to the URL of the original template file. This is essential for
diagnostics messages about the template compilation.
Now the existence of the `template` property overrides the existence of
`templateUrl`, which allows us to keep the `templateUrl` property.
PR Close#28055
In order to support source mapping of templates, we need
to be able to tokenize the template in its original context.
When the template is defined inline as a JavaScript string
in a TS/JS source file, the tokenizer must be able to handle
string escape sequences, such as `\n` and `\"` as they
appear in the original source file.
This commit teaches the lexer how to unescape these
sequences, but only when the `escapedString` option is
set to true. Otherwise there is no change to the tokenizing
behaviour.
PR Close#28055
The lexer that does the tokenizing can now process only a part the source
string, by passing a `range` property in the `options` argument. The
locations of the nodes that are tokenized will now take into account the
position of the span in the context of the original source string.
This `range` option is, in turn, exposed from the template parser as well.
Being able to process parts of files helps to enable SourceMap support
when compiling inline component templates.
PR Close#28055
When we added the strict null checks, the lexer had some `!`
operators added to prevent the compilation from failing.
This commit resolves this problem correctly and removes the
hacks.
Also the comment
```
// Note: this is always lowercase!
```
has been removed as it is no longer true.

This commit consolidates the options that can modify the
parsing of text (e.g. HTML, Angular templates, CSS, i18n)
into an AST for further processing into a single `options`
hash.
This makes the code cleaner and more readable, but also
enables us to support further options to parsing without
triggering wide ranging changes to code that should not
be affected by these new options. Specifically, it will let
us pass information about the placement of a template
that is being parsed in its containing file, which is essential
for accurate SourceMap processing.

We currently face a lot of flakiness with our
Saucelabs CI jobs. These randomly exceed the 10min
CircleCI no-output limit because something throws
off `sauce-connect` in a long-lasting loop where
it tries to connect to some of their Saucelabs
servers. The initial assumption from the Saucelabs
team was that we might have some invalid firewall
rules, but this does not answer why this happens
_randomly_, so the latest update from the support
is that there have been some changes in the latest
version of `sauce-connect` version that **could**
cause this flakiness.
I've manually did multiple test runs and was only
able to reproduce the issues with v4.5.3 (latest
version), so it might be worth downgrading to
v4.5.1. This is also what the Saucelabs support
proposed us to do (though it's not guaranteed that
v4.5.1 is unaffected by the same issue)
