Part of the CI pipeline is generating the tarball, debian and redhat packages for each commit, which are now stored under nightlies. And we now have those for ARM, for example: https://nightlies.apache.org/cassandra/trunk/Cassandra-trunk-artifacts/519/Cassandra-trunk-artifacts/jdk=jdk_11_latest,label=cassandra-arm64/build/ Going from nightlies to releases, the biggest challenge I see is the gpg signing of them. >From ASF INFRA's policy¹ on releases: • Private keys must not be stored on any ASF machine. Likewise, signatures for releases must not be created on ASF machines. I don't know how Hadoop's release process² deals with it in its create-release script³. From the 3.3.0 release, all staged artefacts are listed together…⁴ But my understanding of it all is that we can't create ARM specific releases until we have a release manager that owns an ARM machine where they can keep their gpg private key. It might be possible to create a release via SSH and gpg-agent⁵ if we update our release scripts⁶, but this should be double-checked with INFRA. To move forward on the issue, we need the following information: - how is hadoop creating (and gpg signing) multi-architecture releases? Is it from multiple `create-release` executions? - are there other apache projects doing multi-architecture releases? are they part of one release, or separately created and labelled releases? how are they doing the gpg signing? - can we SSH gpg-agent sign releases on hardware the release manager does not own? > Or add an announcement about ARM platform support in Cassandra doc ? Absolutely! I hope this becomes one significant part of the 4.0 announcement. regards, Mick [1] https://infra.apache.org/release-distribution.html#sigs-and-sums [2] https://cwiki.apache.org/confluence/display/HADOOP2/HowToRelease [3] https://github.com/apache/hadoop/blob/trunk/dev-support/bin/create-release [4] https://home.apache.org/~brahma/Hadoop-3.3.0-RC0/ [5] https://wiki.gnupg.org/AgentForwarding [6] https://github.com/apache/cassandra-builds/tree/trunk/cassandra-release --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@cassandra.apache.org For additional commands, e-mail: dev-h...@cassandra.apache.org
