Synnefo

Continuous integration with Jenkins

===================================

Preparing a GIT mirror

----------------------

Jenkins cannot currently work with Git over encrypted HTTP. To solve this

problem we currently mirror the central Git repository locally on the jenkins

installation machine. To setup such a mirror do the following:

-edit .netrc

machine code.grnet.gr

login accountname

password accountpasswd

-Create the mirror

git clone --mirror https://code.grnet.gr/git/synnefo synnefo

-Setup cron to pull from the mirror periodically. Ideally, Git mirror updates

should run just before Jenkins jobs check the mirror for changes.

4,14,24,34,44,54 * * * * cd /path/to/mirror && git fetch && git remote prune origin

Jenkins setup

-------------

The following instructions will setup Jenkins to run synnefo tests with the

SQLite database. To run the tests on MySQL and/or Postgres, step 5 must be

replicated. Also, the correct configuration file must be copied (line 6 of the

build script).

1. Install and start Jenkins. On Debian Squeeze:

   wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | apt-key add -

   echo "deb http://pkg.jenkins-ci.org/debian binary/" >>/etc/apt/sources.list

   echo "deb http://ppa.launchpad.net/chris-lea/zeromq/ubuntu lucid main" >> /etc/apt/sources.list

   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C7917B12  

   sudo apt-get update

   sudo apt-get install jenkins

   Also install the following packages:

   apt-get install python-virtualenv libcurl3-gnutls libcurl3-gnutls-dev

                   uuid-dev libmysqlclient-dev libpq-dev libsqlite-dev

                   python-dev libzmq-dev

2. After Jenkins starts, go to

   http://$HOST:8080/pluginManager/

   and install the following plug-ins at

   -Jenkins Cobertura Plugin

   -Jenkins Email Extension Plugin

   -Jenkins GIT plugin

   -Jenkins SLOCCount Plug-in

   -Hudson/Jenkins Violations plugin

3. Configure the Jenkins user's Git details:

   su jenkins

   git config --global user.email "buildbot@lists.grnet.gr"

   git config --global user.name "Buildbot"

4. Make sure that all system-level dependencies specified in README.develop

   are correctly installed

5. Create a new "free-style software" job and set the following values:

-Project name: synnefo

-Source Code Management: Git

-URL of repository: Jenkins Git does not support HTTPS for checking out directly

                    from the repository. The temporary solution is to checkout

                    with a cron script in a directory and set the checkout path

                    in this field

-Branches to build: master and perhaps others

-Git->Advanced->Local subdirectory for repo (optional): synnefo

-Git->Advanced->Prune remote branches before build: check

-Repository browser: redmineweb,

                     URL: https://code.grnet.gr/projects/synnefo/repository/

-Build Triggers->Poll SCM: check

                 Schedule: # every five minutes

			   0,5,10,15,20,25,30,35,40,45,50,55 * * * * 

-Build -> Add build step-> Execute shell

Command:

#!/bin/bash -ex

cd synnefo

mkdir -p reports

/usr/bin/sloccount --duplicates --wide --details api util ui logic auth > reports/sloccount.sc

cp conf/ci/manage.py .

if [ ! -e requirements.pip ]; then cp conf/ci/pip-1.2.conf requirements.pip; fi

cat settings.py.dist conf/ci/settings.py.sqlite > settings.py

python manage.py update_ve

python manage.py hudson api db logic 

-Post-build Actions->Publish JUnit test result report: check

                     Test report XMLs: synnefo/reports/TEST-*.xml

-Post-build Actions->Publish Cobertura Coverage Report: check

                     Cobertura xml report pattern: synnefo/reports/coverage.xml

-Post-build Actions->Report Violations: check

                     pylint[XML filename pattern]: synnefo/reports/pylint.report

-Post-build Actions->Publish SLOCCount analysis results

                     SLOCCount reports: synnefo/reports/sloccount.sc

                     (also, remember to install sloccount at /usr/bin)
