Wire v4.0.0-alpha.1 Release Notes

  • 2021-05-01

    Kotlin + Java

    • New: GrpcClient.Builder.minMessageToCompress() configures which messages are compressed. This will completely disable compression if the size is Long.MAX_VALUE. We've seen problems where some Golang gRPC servers don't support compression; setting this to MAX_VALUE is necessary to interop with them.
    • New: SchemaReflector is our initial implementation of the [gRPC Server Reflection Protocol][reflect]. Note that although we implement the business logic of gRPC reflection, we don't offer a gRPC server built into Wire.
    • New: Support rpcRole = 'none' in the Gradle plugin to generate neither client nor server code.
    • Fix: Generate @Deprecated annotations on deprecated messages, fields, enums, and enum constants.
    • Fix: Update the Wire Gradle plugin to register generated .java sources with the Java compiler. Previously this was broken if the Kotlin plugin was installed.
    • Fix: Use Gradle's logging mechanism to reduce output when Wire generates code.
    • Fix: Update the Wire Gradle plugin to clear the output directory before generating code. This prevents the need to do a clean build after removing a message type.
    • Fix: Permit values other than 0 and 1 when decoding protobuf-encoded booleans. Previously we threw an IOException for other values; now all non-zero values are true.
    • Upgrade: [Okio 3.0.0-alpha.3][okio_3_0_0_a_3]. We now use Okio 3's FileSystem in SchemaLoader, which makes it easier to load .proto files from the classpath.

    Swift:

    • New: Support Timestamp and Duration.
    • Fix: Throw an error when encountering an unexpected ProtoReader.beginMessage() rather than calling fatalError().
