Introduction

cms-bot started as a single script used to drive PR approval and grew to be the core of the whole release engineering process for CMSSW.

Setup

To have it working you’ll need a ~/.github-token which can access the cms-sw organization.

Release integration

process-pull-request: this is the script which updates the status of a CMSSW PR. It parses all the messages associated to the specified PR and if it spots a transition (e.g. a L2 signature) it posts a message acknowledging what happended, updates the tags etc. The state of the PR is fully obtained by parsing all the comments, so that we do not have to maintain our own state tracking DB. It is run by CMS Github Bot in jenkins.
run-pr-tests: Runs several tests for the pull requests, this includes compilation, unit tests, relvals, and static analysis, among other tests. It is run by ib-any-integration in Jenkins.
watchers.yaml: contains all the information required by process-pull-requests to notify developers when a PR touches the packages they watch.

Release building

process-build-release-request: script that handles the github issue used to request the build.
build-release: script used to build a release which has been requested through a Github issue.
upload-release: script used to upload a release to the repository. When the job processing build requests spots a request to upload, it SSH to the build machine which has the release and executes this script.

Logging

Logging happens at many different level but we are trying to unify things using Elasticsearch for “live” data from which we dump precomputed views on a basis.

es-templates: contains the templates for the logged dataes-templates.
es-cleanup-indexes: cleanups old indexes in elasticsearch.

IB Pages

The IB pages can bee seen here.

summary-of-merged-prs is the jenkins job that generates and deploys the pages.
report-summary-merged-prs is the script that generates the json files with the information that the pages show.

Cleanup of cmssdt

cleanup-cmssdt: takes care of cleaning up disk space in vocms12.
cleanup-cmssdt01: takes care fo cleaning up disk space in cmssdt01. This machine is currently used for the jenkins artifacts.

Automatic Forward Ports.

update-cmssw-7-0-X-branches: takes care of forward porting changes between cmsssw and cmssdt branches. It runs auto-update-git-branches.
