Motivation: The main use case with Buf.compact is in conjunction with ensureWritable. It turns out we can get a simpler API, and faster methods, by combining those two operations, because it allows us to relax some guarantees and skip some steps in certain cases, which wouldn't be as neat or clean if they were two separate steps. Modification: Add a new Buf.ensureWritable method, which takes an allowCompaction argument. In MemSegBuf, we can just delegate to compact() when applicable. In CompositeBuf, we can sometimes get away with just reorganising the bufs array. Result: We can now do ensureWritable without allocating in some cases, and this can in particular make the operation faster for CompositeBuf.
Netty Incubator Buffer API
This repository is incubating a new buffer API proposed for Netty 5.
Building and Testing
Short version: just run make.
The project currently relies on snapshot versions of the Panama Foreign fork of OpenJDK.
This allows us to test out the must recent version of the jdk.incubator.foreign APIs, but also make building and local development more involved.
To simplify things, we have a Docker based build, controlled via a Makefile with the following commands:
image– build the docker image. This includes building a snapshot of OpenJDK, and download all relevant Maven dependencies.test– run all tests in a docker container. This impliesimage. The container is automatically deleted afterwards.dbg– drop into a shell in the build container, without running the build itself. The debugging container is not deleted afterwards.clean– remote the debugging container created bydbg.build– build binaries and run all tests in a container, and copy thetargetdirectory out of the container afterwards. This is the default build target.
