For now, we always create all generated files, but diff them
before we pass them to TypeScript.
For the user files, we compare the programs and only emit changed
TypeScript files.
This also adds more diagnostic messages if the `—diagnostics` flag
is passed to the command line.
Closure no longer needs to have the imports rewritten avoid rewriting
as this can cause issues when the source directory structure differs
from what is deployed.
Fixes: #19026
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 6e3498ca8e.
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.
