Missing aleph.utils.PluggableDnsAddressResolverGroup #616

Closed pavel-klavik closed 2 years ago

pavel-klavik commented 2 years ago

I have a project when an upgrade from aleph-0.4.6 to 0.5.0 fails with the following stacktrace:

Any idea what could be causing this? The code does not interact with Aleph much, just starts the server at the beginning:

(http/start-server #'handler/handler {:socket-address (InetSocketAddress. host port)
                                          :epoll?         (Epoll/isAvailable)
                                          :ssl-context    (when (and dev https) (tls-context))})

Hello Pavel!

Before digging too deeply, we have removed the usage of aleph.utils.PluggableDnsAddressResolverGroup. It's not present anymore on the code-base, it has been removed by the following PR : https://github.com/clj-commons/aleph/pull/399/files.

Maybe you have a mismatch between multiple aleph versions. What is the state of your deps?

KingMob commented 2 years ago

Hi Pavel.

In addition to what Arnaud said, what's the context you're using Aleph in? This sounds a lot like the sort of problem we see when multiple versions of a library end up on the classpath. Usually including an uberjar by accident is the reason. (E.g., Jepsen has a similar issue, related to deploying an uberjar that includes byte-streams and manifold.)

I would check for any uberjars in your classpath first. If in doubt, unzip them, look at the file list, and if any jars contain files/classes from elsewhere, they might be uberjars. Also, let us know if you're doing this with graal.

Based on the stacktrace, you're using orgpad-server, and looking at its project.clj, the first thing that looks suspicious is the dep on duct/server.http.aleph. Also, onyx-platform apparently used to use Aleph, and its onyx-http plugin looks like it still does.

That being said, neither appear to build uberjars like orgpad-server itself does. If you were using the orgpad-server uberjar as a dep in another project, that might be the most likely cause of the problem.

Thanks for the pointers. I checked my dependencies with lein deps :tree, but I couldn't find aleph included multiple times. The mentioned orgpad is our project itself. In the end, I tried to run lein clean and that fixed the problem.
