0.95.0 release notes

26th October 2019

🥳 New features

You can now bind multiple paths to an annotated service easily using @Path. #1822 #1870
```
@Get
@Post
@Path("/a")
@Path("/b")
public String myAwesomeServcie(...) {...}
```
You can now make an annotated service run from blockingTaskExecutor by attaching @Blocking. #2078, #2187
```
@Get("/myHeavyTask")
@Blocking
public HttpResponse reallyHeavyComputation(...) {...}
```

Armeria server now adds Server and Date headers to responses by default. #2137, #2188

If you do not want that behavior, you should call:

Server.builder()
      .service(...)
      .disableServerHeader()
      .disableDateHeader()
      .build();

You can now configure a Caffeine cache spec for HttpFileService. #916, #2142

HttpFileServiceBuilder.forClassPath("/")
                      .entryCacheSpec("maximumSize=512")
                      .build()

Or, using JVM option: -Dcom.linecorp.armeria.fileServiceCache=maximumSize=1024,expireAfterAccess=600s

You can now see the Armeria version in the metric. #2179

💪 Improvements

Armeria server startup time is reduced to 80 percent when TLS is not used. #1645, #2184
The performance of getting HTTP timestamps is improved by caching the values every second. #2196
- Use HttpTimestampSupplier.currentTime() to take advantage of it.
The performance of finding service is improved by not making an unused Map in RouteResult. #2153
The performance of gRPC call is improved by using the singleton HTTP headers when a service does not create a new HTTP headers. #2152
The performance of making metric Tags is improved by adding Tags in ascending order. #2150, #2163
We now have favicon in our DocService. #2186

👻 Bug fixes

ServerHttpRequest.getRemoteAddress() now returns proper address. #2208
You can now see descriptive error messages when sslContext is not configured properly. #1844, #2124
You can now build (Request|Response)Headers multiple times using builders. #2190, #2193
- Previously, it raised ClassCastException if build() is called twice.

NoRequestContextException is not raised anymore if you configure the name of the non-request thread.

RequestContextCurrentTraceContext.builder()
                                 .nonRequestThread("RMI TCP Connection")
                                 .build()

NullPointerException is not raised anymore in Http1ClientCodec when the server sends multiple responses for one request. #2210
You can now see the access logs when the method of a request is not allowed and there are no services that match the path. #2159

🚫 Breaking changes

All annotated services are run from EventLoop by default. #2187
- Previously, if the return type is neither HttpResponse nor CompletableFuture, annotated services are run from blockingTaskExecutor.
ServerBuilder.tls() now throws a checked SSLException. #2124
ServerBuilder.sslContext() methods are completely removed. #2124
