armeria-0.43.0

New features

• #499 Unframed GRPC support

• #504 Allow adding a listener to any EndpointGroup implementations

  • Add Listeneable and AbstractListenable as a common utility

• #507 More convenient deferred construction of RpcResponse and HttpResponse

  • Before:

    // RpcResponse
    DefaultRpcResponse res = new DefaultRpcResponse();
    CompletableFuture<Object> future = doAsync();
    future.whenComplete((value, cause) -> {
        if (cause != null) {
            res.completeExceptionally(cause);
        } else {
            res.complete(value);
        }
    });
    return res;
    
    // HttpResponse
    DeferredHttpResponse res = new DeferredHttpResponse();
    CompletableFuture<HttpResponse> future = doAsync();
    future.whenComplete((actualRes, cause) -> {
        if (cause != null) {
            res.close(cause);
        } else {
            res.delegate(actualRes);
        }
    });
    return res;

  • After:

    // RpcResponse
    return RpcResponse.from(doAsync());
    
    // HttpResponse
    return HttpResponse.from(doAsync());

• #507 Add RpcResponse.join() and RpcResponse.getNow()

• #507 Add Exceptions.throwUnsafely()

Known issues

• This release depends on Netty 4.1.9, which has a bug related with domain name resolution. If you are in an IPv4 environment, specify the -Djava.net.preferIPv4Stack=true option to work around it. We will release a new version that depends on the Netty version with the fixes once it's available.
