0.3.5

This is a relatively small release. It incorporates a new version of Elle which brings dramatic performance improvements, and has a few quality-of-life improvements.

Bugfixes

• os.debian/install and remove now acquire locks, which means you can do multiple debian-package-affecting operations concurrently against a single node.
• Thread/sleep callsites now have explicit integer coercion, fixing a crashes in newer JVMs/Clojure.

API Changes

• control.util/grepkill! now matches the full pattern of the process, rather than just the first 15 characters. This is particularly helpful for killing, say, one out of several java processes.
• net/Net has been moved to net.proto/Net. All its functions are still available in jepsen.net too.

New Features

• checker.perf: nemesis specifications can now include :hidden? true, which prevents them from appearing on graphs.

Minor Changes

• fs-cache/deploy-remote! returns the remote path it uploaded, making it easier to thread into other expressions.
• control.util/install-archive! now has docs that explain the use of file:// URLs.
• net/drop! now uses existing SSH connections, making it faster
• net/drop! has a clearer docstring
• Elle 0.2.1
• SSHJ 0.38.0
• Ring 1.11.0
