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)

API Deprecations

Developer note: Additional API deprecation advisories and guidance have been added in each of the 0.41.X releases. Please build your application with the latest 0.41.X release and carefully review the deprecation warnings reported and associated suggestions. Changes to applications may be required for compatibility with future versions of ServiceTalk beyond the API compatible 0.41.X series. While there are many deprecations for planned future API changes, most applications should require few changes as the most significant changes are to internal or specialized APIs. If you have concerns or expect problems related to any of the API deprecations please report these as an issue.
