Added the compiler options `strictInjectionParameters` that defaults
to `false`. If enabled the compiler will report errors for parameters
of an `@Injectable` that cannot be determined instead of generating a
warning.
This is planned to be switched to default to `true` for Angular 6.0.
Also adds auto upgrade from lower version based
on the .d.ts file (e.g. from version 3 to 4).
This is needed as we are now also capturing type aliases
in metadata files (and we rely on this),
see 6e3498ca8e6752c0d59c19c89e3211744e80f6d8.
The new expression lowering lowers everything after `useValue` / `useFactory`
into a separate exported variable. If the value was a `forwardRef`, this
was passed to the runtime and resulted in errors.
This change unwraps `forwardRef`s during runtime again.
Note: we can’t unwrap the `forwardRef` into an exported variable
during compile time, as this would defeat the purpose of the
`forwardRef` in referring to something that can’t be referred to
at this position.
introduce the option `allowEmptyCodegenFiles` to generate all generated files,
even if they are empty.
- also provides the original source files from which the file was generated
in the write file callback
- needed e.g. for G3 when copying over pinto mod names from the original component
to all generated files
use `importAs` from flat modules when writing summaries
- i.e. prevents incorrect entries like @angular/common/common in the .ngsummary.json files.
change interaction between ng and ts to prevent race conditions
- before Angular would rely on TS to first read the file for which we generate files,
and then the generated files. However, this can break easily when we reuse an old program.
don’t generate files for sources that are outside of `rootDir`
(see #19337)
With this commit `ngc` is used instead of `tsc-wrapped` for
collecting metadata and tsickle rewriting and `tsc-wrapped`
is removed from the repository.
`@angular/tsc-wrapped@5` is now deprecated and is no longer
used, updated, or maintained as part as of Angular 5.x.x.
`@angular/tsc-wrapped@4` is still maintained and required by
Angular 4.x.x and will be maintained as long as 4.x.x is in
LTS.

- don’t regenerate code for .d.ts files when
an oldProgram is passed to `createProgram`
- cache `fileExists` / `getSourceFile` / `readFile` in watch mode
- refactor tests to share common code in `test_support`
- support `—diagnostic` command line to print total time
used per watch mode compilation.

This flag controls whether the compiler emits generated files.
It is initially calculated via `skipTemplateCodegen` from the
compiler options.
Also:
- adds a small performance improvement to not generate the files
at all if we don’t emit generated code.
- removes `EmitFlags.Summaries` as we never used it.
PR Close#19275
We now create 2 programs with exactly the same fileNames and
exactly the same `import` / `export` declarations,
allowing TS to reuse the structure of first program
completely. When passing in an oldProgram and the files didn’t change,
TS can also reuse the old program completely.
This is possible buy adding generated files to TS
in `host.geSourceFile` via `ts.SourceFile.referencedFiles`.
This commit also:
- has a minor side effect on how we generate shared stylesheets:
- previously every import in a stylesheet would generate a new
`.ngstyles.ts` file.
- now, we only generate 1 `.ngstyles.ts` file per entry in `@Component.styleUrls`.
This was required as we need to be able to determine the program files
without loading the resources (which can be async).
- makes all angular related methods in `CompilerHost`
optional, allowing to just use a regular `ts.CompilerHost` as `CompilerHost`.
- simplifies the logic around `Compiler.analyzeNgModules` by introducing `NgAnalyzedFile`.

This speeds up the compilation process significantly.
Also introduces a new option `fullTemplateTypeCheck` to do more checks in templates:
- check expressions inside of templatized content (e.g. inside of `<div *ngIf>`).
- check the arguments of calls to the `transform` function of pipes
- check references to directives that were exposed as variables via `exportAs`
PR Close#19152
- temporarily keeps the old sources under packages/tsc-wrapped
until the build scripts are changed to use compiler-cli everywhere.
- removes the compiler options `disableTransformerPipeline` that was introduced
in a previous beta of Angular 5, i.e. the transformer based compiler
is now always enabled.

BREAKING CHANGE: the compiler option `enableLegacyTemplate` is now disabled by default as the `<template>` element has been deprecated since v4. Use `<ng-template>` instead. The option `enableLegacyTemplate` and the `<template>` element will both be removed in Angular v6.

This is a corner case, and converting them is what
was expected in G3. This also fits the fact that
we already convert package paths into relative paths.

With this change ngc now accepts a `-w` or a `--watch`
command-line option that will automatically perform a
recompile whenever any source files change on disk.
PR Close#18818
With this commit the compiler will "lower" expressions into exported
variables for values the compiler does not need to know statically
in order to be able to generate a factory. For example:
```
providers: [{provider: 'token', useValue: calculated()}]
```
produced an error as the expression `calculated()` is not supported
by the compiler because `calculated` is not a
[known function](https://angular.io/guide/metadata#annotationsdecorators)
With this commit this is rewritten, during emit of the .js file, into
something like:
```
export var ɵ0 = calculated();
...
provdiers: [{provider: 'token', useValue: ɵ0}]
```
The compiler then will now generate a reference to the exported `ɵ0`
instead of failing to evaluate `calculated()`.
