The size diff threshold of 1% has proven to be too lenient for us
to catch size regressions in AIO. Since the AIO main bundle is
between 400-500 KB, a size regression must be between 4-5 KB before
it will cause the tests to fail. As a result, we may merge many
changes with smaller regressions of a few KB before the size test
eventually lets us know that the number has increased. The hope is
that lowering the threshold will help us catch the smaller
regressions during code review and prevent the size tests failing at
a random later time when someone catches the size "hot potato".

It will be easier to track regressions in size if fewer people
are approving size diffs in PRs. That way, we will have a few
people that have a fuller picture of where size changes are
coming from.

In efbbae5a4, the `publish_packages_as_artifacts` CircleCI job was
created to publish the build artifacts of PR builds on CI. In a8f4f14bd,
its scope was expanded to also publish build artifacts on non-PR builds.
The published artifacts names are constructed based on the PR number
(e.g. include `-pr12345-`), so on non-PR builds the names do not reflect
the source branch (instead, they include `-prfalse-`).
This commit fixes this by using the current branch name. For example,
artifact names for the `master` or `9.0.x` branch will include
`-master-` and `-9.0.x-` respectively (instead of `-prfalse-`).
(NOTE: For PRs, where branch name is `pull/12345`, the branch name is
transformed to `pr12345`.)

In a package.json file, the "typings" or "types" field could be an array
of typings files. ngcc would previously crash unexpectedly for such
packages, as it assumed that the typings field would be a string. This

entry-points is not supported for Angular packages so it is safe to

The assertion that we have in the `directiveInject` instruction is too restrictive and we came across some pattern where it throws unnecessarily. This commit removes that assertion for now and more detailed investigation is needed to decide is we need to restrict the set of TNodeType again.
This commit also adds a test which triggered the TNodeType.View to come up in the `directiveInject` instruction, so it might be useful to avoid regressions during further refactoring.

Due to the fact that Tsickle runs between analyze and transform phases in Angular, Tsickle may transform nodes (add comments with type annotations for Closure) that we captured during the analyze phase. As a result, some patterns where a function is returned from another function may trigger automatic semicolon insertion, which breaks the code (makes functions return `undefined` instead of a function). In order to avoid the problem, this commit updates the code to wrap all functions in some expression ("privders" and "viewProviders") in parentheses.

When ngtsc comes across a source file during partial evaluation, it
would determine all exported symbols from that module and evaluate their
values greedily. This greedy evaluation strategy introduces unnecessary
work and can fall into infinite recursion when the evaluation result of
an exported expression would circularly depend on the source file. This
would primarily occur in CommonJS code, where the `exports` variable can
be used to refer to an exported variable. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,
thereby greedily evaluating all exported symbols and thus ending u
evaluating the `exports` variable again. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,
thereby greedily evaluating all exported symbols and thus ending up

until all stack frames were exhausted.
This commit introduces a `ResolvedModule` that delays the evaluation of
its exports until they are actually requested. This avoids the circular
dependency when evaluating `exports`, thereby fixing the issue.

The template type checker generates code to check directive inputs and
outputs, whose name may contain characters that can not be used as
identifier in TypeScript. Prior to this change, such names would be

This commit fixes the bug by representing the potentially invalid names

NgModule compilation in JIT mode (that is also used in TestBed) caches module scopes on NgModule defs (using `transitiveCompileScopes` field). Module overrides (defined via TestBed.overrideModule) may invalidate this data by adding/removing items in `declarations` list. This commit forces TestBed to recalculate transitive scopes in case module overrides are present, so TestBed always gets the most up-to-date information.

Previously, the generated StackBlitz examples as well as the
corresponding downloadable zips for the `http` guide examples were not
correct and thus trying to run the app and/or tests would fail.
This commit fixes the examples:
- Replace `TestBed.inject()` (which was [introduced in v9][1]) with
`TestBed.get()` (which is available in v8 used in the examples).
(NOTE: The examples will soon be updated to v9 (as part of
[FW-1609][2] and switched back to `TestBed.inject()` then.)
- Include `src/app/heroes/hero.ts` in the zip, because it is referenced
by some of the other files and the compilation fails without it.
- Ensure `src/main-specs.ts` is not included in the zip that does not
include the tests. Including the file broke the app, because there is
logic in our zip-builder that renamed `main-*.ts` files to `main.ts`
and thus `main-specs.ts` ended up overwriting the actual `main.ts`.

This commit transforms the setClassMetadata calls generated by ngtsc from:
```typescript
/*@__PURE__*/ setClassMetadata(...);
```
to:
```typescript
/*@__PURE__*/ (function() {
setClassMetadata(...);
})();
```
Without the IIFE, terser won't remove these function calls because the
function calls have arguments that themselves are function calls or other
impure expressions. In order to make the whole block be DCE-ed by terser,
we wrap it into IIFE and mark the IIFE as pure.
It should be noted that this change doesn't have any impact on CLI* with
build-optimizer, which removes the whole setClassMetadata block within
the webpack loader, so terser or webpack itself don't get to see it at
all. This is done to prevent cross-chunk retention issues caused by
webpack's internal module registry.
* actually we do expect a short-term size regression while
https://github.com/angular/angular-cli/pull/16228
is merged and released in the next rc of the CLI. But long term this
change does nothing to CLI + build-optimizer configuration and is done
primarly to correct the seemingly correct but non-function PURE annotation
that builds not using build-optimizer could rely on.

NgModules in Ivy have a definition which contains various different bits
of metadata about the module. In particular, this metadata falls into two
categories:
* metadata required to use the module at runtime (for bootstrapping, etc)
in AOT-only applications.
* metadata required to depend on the module from a JIT-compiled app.
The latter metadata consists of the module's declarations, imports, and
exports. To support JIT usage, this metadata must be included in the
generated code, especially if that code is shipped to NPM. However, because
this metadata preserves the entire NgModule graph (references to all
directives and components in the app), it needs to be removed during
optimization for AOT-only builds.
Previously, this was done with a clever design:
1. The extra metadata was added by a function called `setNgModuleScope`.
A call to this function was generated after each NgModule.
2. This function call was marked as "pure" with a comment and used
`noSideEffects` internally, which causes optimizers to remove it.
The effect was that in dev mode or test mode (which use JIT), no optimizer
runs and the full NgModule metadata was available at runtime. But in
production (presumably AOT) builds, the optimizer runs and removes the JIT-
specific metadata.
However, there are cases where apps that want to use JIT in production, and
still make an optimized build. In this case, the JIT-specific metadata would
be erroneously removed. This commit solves that problem by adding an
`ngJitMode` global variable which guards all `setNgModuleScope` calls. An
optimizer can be configured to statically define this global to be `false`
for AOT-only builds, causing the extra metadata to be stripped.
A configuration for Terser used by the CLI is provided in `tooling.ts` which
sets `ngJitMode` to `false` when building AOT apps.

The Ivy template type-checker is capable of inferring the type of a
structural directive (such as NgForOf<T>). Previously, this was done with
fullTemplateTypeCheck: true, even if strictTemplates was false. View Engine
previously did not do this inference, and so this causes breakages if the
type of the template context is not what the user expected.
In particular, consider the template:
```html
<div *ngFor="let user of users as all">
{{user.index}} out of {{all.length}}
</div>
```
As long as `users` is an array, this seems reasonable, because it appears
that `all` is an alias for the `users` array. However, this is misleading.
In reality, `NgForOf` is rendered with a template context that contains
both a `$implicit` value (for the loop variable `user`) as well as a
`ngForOf` value, which is the actual value assigned to `all`. The type of
`NgForOf`'s template context is `NgForContext<T>`, which declares `ngForOf`'s
type to be `NgIterable<T>`, which does not have a `length` property (due to
its incorporation of the `Iterable` type).
This commit stops the template type-checker from inferring template context
types unless strictTemplates is set (and strictInputTypes is not disabled).

Previously, the ngtsc compiler attempted to reuse analysis work from the
previous program during an incremental build. To do this, it had to prove
that the work was safe to reuse - that no changes made to the new program
would invalidate the previous analysis.
The implementation of this had a significant design flaw: if the previous
program had errors, the previous analysis would be missing significant
information, and the dependency graph extracted from it would not be
sufficient to determine which files should be re-analyzed to fill in the
gaps. This often meant that the build output after an error was resolved
would be wholly incorrect.
This commit switches ngtsc to take a simpler approach to incremental
rebuilds. Instead of attempting to reuse prior analysis work, the entire
program is re-analyzed with each compilation. This is actually not as
expensive as one might imagine - analysis is a fairly small part of overall
compilation time.
Based on the dependency graph extracted during this analysis, the compiler
then can make accurate decisions on whether to emit specific files. A new
suite of tests is added to validate behavior in the presence of source code
level errors.
This new approach is dramatically simpler than the previous algorithm, and
should always produce correct results for a semantically correct program.s
