ErrorCatcher renderers do not have access to the response object.

[kamarton]

What steps will reproduce the problem?

yiisoft/yii-web#146 issues would require you to add headers to the response. It is also required for other applications where a change in the cache header is warranted in the response, e.g. if the error is persistent, it may be appropriate to use stale-if-error with a higher value.

What do you get instead?

It is not currently available.

I see multiple ways solving it:

1. We may merge ErrorCatcher and ErrorHandler. But I don't like the solution because ErrorHandler is used also for fatal errors that aren't in the context of PSR-7 request-response.
2. We may make renderer return headers as well. That would work but we have to rename it somehow since it won't be strictly rendering anymore.

I prefer this solution. What you may need:

• override headers (array list)
• status code override (int)
  At the moment, I think these are enough.

Like this?

class ThrowableRenderer
{
    // ...
    public function render(\Throwable $t): RenderedError;
}

class RenderedError
{
    public function getBody(): string;
    public function getHeaders(): array;
    public function getStatusCode(): int;
}
