Announcing WildFly Swarm 2017.9.4

WildFly Swarm 2017.9.4

What a strange release number. Indeed.

We’ve been struck by some weird release problems, which forced us to burn a number of versions (x.9.0-x.9.3). If you care about the details, here’s a description of the issue we ran into: https://issues.sonatype.org/browse/NEXUS-9138

What’s New?

  • Topology.js Changes

  • Gradle enhancements

  • Consul Fixes and enhancements

  • Assorted minor bugfixes

Topology.js Changes

WARNING: Breaking change!

Previously, the topology.js script provided by the topology-webapp fraction exposed a simple topology() function that you used like this:

var Topology = topology();
... code using Topology ...

This was prone to race conditions, because you could start using Topology before the initial topology was obtained from the server.

Code like this will no longer work. The topology() function now returns a promise, which is only resolved when initial topology is obtained from the server. The code above needs to be transformed to look like this:

topology().then(function (Topology) {
    ... code using Topology ...
});

Now, you only get the Topology object when it is ready to be used.

Gradle enhancements

Gradle introduced seperate output directories for each jvm language in version 4. Therefore, when running Swarm from the IDE, resolving the build classes directory did fail. This should now be fixed.

Consul Fixes and enhancements

When trying to shutdown the application (via CTR-C or kill SIGTERM) the server tries to deregister the services from Consul multiple times and after a (seemingly) random number of log entries freezes and hangs. Amongst these fixes, are further enhancements that make the Consul integration more robust.
