(core): Ability to turn off specific deprecations

[moltar]

Describe the feature

I'd like to be able to turn off (ack) some deprecation notices, but keep others.

Use Case

Turn off DnsValidatedCertificate notice.

We know the issue, but there is currently no good solution or path forward. The feature was deprecated without a matching replacement.

This warning shows up everywhere in our workflows and is very annoying. It can also cause warning blindness eventually, as developers learn to ignore it, but can also ignore others.

I want to be able to turn off this specific deprecation.

Proposed Solution

N/A

Other Information

    console.warn
Warning: RNING] aws-cdk-lib.aws_certificatemanager.DnsValidatedCertificate is deprecated.
        use {@link Certificate} instead
        This API will be removed in the next major release.

Yes this makes sense.

Another source of annoyance is aws-cdk-lib.aws_ec2.MachineImage#latestAmazonLinux.

[WARNING] aws-cdk-lib.aws_ec2.MachineImage#latestAmazonLinux is deprecated.
  use MachineImage.latestAmazonLinux2 instead
  This API will be removed in the next major release.

And this warning is coming from the CDK's own BastionHost construct, which is not upgraded due to the breaking nature of the change (#25310).

Workaround in Clojure/Java is to manually filter System/err:

(ns ...
  (:import [java.io PrintStream]
           [java.nio.charset StandardCharsets]))

; HACK: suppress "[WARNING] aws-cdk-lib.aws_certificatemanager.DnsValidatedCertificate is deprecated" log.
; The log originates from System.err.write call in software.amazon.jsii.JsiiRuntime.ErrorStreamSink.
; https://github.com/aws/aws-cdk/issues/25343, https://github.com/aws/aws-cdk/issues/24512.
(System/setErr
  (proxy [PrintStream] [System/err]
    (write
      ([x]
       (proxy-super write x))
      ([^bytes buf off len]
       (let [s (String. buf StandardCharsets/UTF_8)]
         (when (not (str/includes? s "DnsValidatedCertificate is deprecated"))
           (proxy-super write buf off len)))))))
