0.42.19

This is a minor maintenance release appropriate for all ServiceTalk users that contains several useful improvements and bug fixes. This release is expected to be a "drop-in" replacement for all prior 0.42.X releases.

Changes

Bug Fixes

• f927517 - gRPC: apply default timeout filter before user-supplied HTTP client filters (#2390)
  • Position of the filter that serves gRPC deadline (defaultTimeout) feature moved from the end of the client filter chain to the beginning. It ensures the deadline covers all business logic, including all appended filters, and prevents situations when an added filter can deadlock. Note that starting from this release, any manual modifications for the grpc-timeout header won't have an effect on the actual timeout duration for the client. If you need to change its value before the timeout is scheduled, use DefaultGrpcClientMetadata#timeout() for per-request modifications.
• aebad36 - Buffer.[set|write]Bytes doesn't respect length when reading from InputStream (#2389)
• d9d8e93 - RetryingHttpRequesterFilter: drain response before mapping to exception (#2391)

New APIs

• b1a5c53 - Add Publisher#concatPropagateCancel(Completable) to force cancel propagation (#2372)

• 509bec5 - DefaultPayloadInfo: enhance toString() to print all flags separately (#2373)

Changes
