uhttp

This is a native CLI tool created using Clojure and GraalVM. Its main purpose is to prove that unixsocket-http can be compiled using GraalVM.

Build

Make sure you have native-image installed and run:

lein uberjar
$GRAALVM_HOME/bin/native-image -jar target/uhttp.jar -H:Name=uhttp

Afterwards, you should have uhttp binary available. Note that all native-image configuration is part of the Uberjar.

Run

The native image can be run on any platform that provides glibc and is supported by junixsocket (the underlying Java/Native bridge). You also need to ensure that the directory identified by the property java.io.tmpdir exists and is writeable.

uhttp <socket> <path>

This will send an HTTP request over the given UNIX Domain Socket. For example, to ping the Docker daemon:

$ ./uhttp unix:///var/run/docker.sock /_ping
{:status 200, :headers {"api-version" "1.40", "server" "Docker/19.03.2 (linux)", "content-type" "text/plain; charset=utf-8", "content-length" "2", "docker-experimental" "false", "pragma" "no-cache", "date" "Sat, 11 Apr 2020 15:47:35 GMT", "ostype" "linux", "cache-control" "no-cache, no-store, must-revalidate"}, :body "OK"}

uhttp

This will run a small diagnostics program, attempting to load the native library using a mechanism very close to what junixsocket actually does:

$ ./uhttp
Native Library:  libjunixsocket-native-2.3.2.so
  Architecture:  amd64
  OS:            Linux
  Path:          /lib/amd64-Linux-clang/jni/libjunixsocket-native-2.3.2.so
  Temp Dir:      /var/tmp/
Loading native library ...
  Copying to /var/tmp/libtmp2171414089132613831libjunixsocket-native-2.3.2.so ...
  Loading /var/tmp/libtmp2171414089132613831libjunixsocket-native-2.3.2.so ...
  OK!
