TypeScript has a more modern diagnostic emit function which produces
contextually annotated error information, using colors in the console
to indicate where in the code the error occurs.
This commit swiches ngtsc to use this format for diagnostics when
emitting them after a failed compilation.
PR Close#25647
This commit takes the first steps towards ngtsc producing real
TypeScript diagnostics instead of simply throwing errors when
encountering incorrect code.
A new class is introduced, FatalDiagnosticError, which can be thrown by
handlers whenever a condition in the code is encountered which by
necessity prevents the class from being compiled. This error type is
convertable to a ts.Diagnostic which represents the type and source of
the error.
Error codes are introduced for Angular errors, and are prefixed with -99
(so error code 1001 becomes -991001) to distinguish them from other TS
errors.
A function is provided which will read TS diagnostic output and convert
the TS errors to NG errors if they match this negative error code
format.

Previously, benchpress would use `console.time()` and
`console.timeEnd()` to measure the start and end of a test in the
performance log. This used to work over navigations - if you called
`console.time(id)` then navigated to a different page, calling
`console.timeEnd(id)` would still insert an event in the performance
log.
As of Chrome 65, this is no longer the case. `console.timeEnd(id)` will
simply not insert an event in the performance log unless
`console.time(id)` was called on the same page. Likewise, using
`performance.measure()` does not work if the starting mark was on a
different page.
This simple workaround uses `performance.mark()` to insert events in the
performance log at the start and end of the test. Benchpress looks for
'-bpstart' and '-bpend' in the name of the performance mark, and
normalizes that to the start and end events expected by PerflogMetric

When using ViewEncapsulation.ShadowDom, Angular will not remove the child nodes of the DOM node a root Component is bootstrapped into. This enables developers building Angular Elements to use the `<slot>` element to do native content projection.

By pulling in `compiler` into `core` the `compiler` was not
100% tree-shakable and about 8KB of code was retained
when tree-shaken with closure.

Due to unknown reasons, Firebase seems to return a 301 response for
`/index.html`, but without a `Location` header. According to the spec,
the browser will not follow the redirect, considering the response as
failed, instead.
This commit temporarily removes `index.html` from hashed resources and
changes `index` to `/` in `ngsw-config.json`, until we figure out an
appropriate long-term solution.

In tsc 3.0 the check that enables program structure reuse in tryReuseStructureFromOldProgram has changed
and now uses identity comparison on arrays within CompilerOptions. Since we recreate the options
on each incremental compilation, we now fail this check.
After this change the default set of options is reused in between incremental compilations, but we still
allow options to be overriden if needed.

In an overloaded method, the overload with the function body is the
actual method doc, and this doc is not included in the list of "additional"
overloads.
Moreover, the logic (all in dgeni-packages) is that if none of the items
has a body then we use the first overload as the actual method doc.
In the case of abstract methods, none of the methods have a body. So we
have a situation where the overloads collection does not contain the first
abstract method, even though it is not the "implementation" of the method.
Therefore we need to still render it.

This allows URLs to be passed through to the server (where they are
properly redirected), instead of serving `index.html` from the SW.
Known issue:
`/docs/` will be passed through to the server. `/docs` (without the
trailing slash) will be correctly treated as a navigation URL and
handled by the SW.
We don't link to `/docs/` from within the app, but if there are external
links to `/docs/` they will require a round-trip to the server and will
not work in offline mode.
