This tool watches scala/scala for new commits and starts a run of our benchmark suite for every merge commit. The UI is at scala-ci.typesafe.com/benchq.

Admin

Running on the "influxdb" EC2 node, which does not have a static IP or hostname. Add the following to your .ssh/config to tunnel through jenkins-master:

Host jenkins-master
  HostName 54.67.111.226
  User admin

Host jenkins-grafana
  HostName 172.31.0.100
  User ubuntu
  ProxyCommand ssh -q -W %h:%p jenkins-master

CLI

Stop the service, log in as ubuntu (the admin user):

ssh ubuntu@jenkins-grafana
sudo sv down benchq

Use the sbt console in the benchq user (todo: for some reason, I saw all debug-level logs in the console):

ssh benchq@jenkins-grafana
cd compiler-benchq
sbt -Dconfig.file=/home/benchq/benchq-data/conf/application.conf -Dlogger.file=/home/benchq/benchq-data/conf/logback.xml console

scala> knownRevisionService.lastKnownRevision(Branch.v2_12_x)
res0: Option[benchq.model.KnownRevision] = Some(KnownRevision(2.12.x,cbf7daa57d70ccacf8cfc7c2f4a7c0e81e1c773a))

scala> q // to shutdown the application

Restart the service as ubuntu:

ssh ubuntu@jenkins-grafana
sudo sv up benchq

Deployment

• Running on ssh benchq@jenkins-grafana, port 8084.
• Exposed via the scala-ci reverse proxy

Sever admin

ssh ubuntu@jenkins-grafana

Service by runit, here's a tutorial. Script at /etc/service/benchq/run (uses a fat jar by sbt-assembly):

#!/bin/sh -e
exec 2>&1
exec chpst -u benchq -U benchq \
  env HOME=/home/benchq \
  java \
    -Dhttp.port=8084 \
    -Dplay.evolutions.db.default.autoApply=true \
    -Dpidfile.path=/dev/null \
    -Dconfig.file=/home/benchq/benchq-data/conf/application.conf \
    -Dlogger.file=/home/benchq/benchq-data/conf/logback.xml \
    -jar /home/benchq/compiler-benchq/target/scala-2.11/benchq.jar

Push to deploy

• Ordinary (not "bare") clone at /home/benchq/compiler-benchq
• Allow pushes to update the index: git config receive.denyCurrentBranch updateInstead
• post-receive script installed with ln -s ../../scripts/post-receive .git/hooks/post-receive
• Add prod remote to local checkout: git remote add prod ssh://benchq@jenkins-grafana/home/benchq/compiler-benchq
• git push prod master
