Basic CI scripts for Squeak.

Requirements

• ruby 1.9 (but 2.0 should work too)
• cmake
• gcc
• zip
• unzip
• curl

On Windows this assumes you're using Cygwin and pik:

# Install pik
pik install ruby 1.9.3
pik use 193

On other OSes:

# Install RVM (or chruby, or rbenv, or...)
$ \curl -L https://get.rvm.io | bash -s stable --ruby=1.9.3
$ cd squeak-ci
$ which ruby
/home/frank/.rvm/rubies/ruby-1.9.3-p392/bin/ruby

After you have a Ruby installed, set up the initial environment:

$ gem install bundle # if necessary
$ bundle install

How do I contribute?

Report bugs in the issue list, or on [email protected]. Ideally I'd like to see a pull request raised against the master branch, but if you've only got time to drop a mail or a note in the issue tracker, that's fine too.

Volunteering to run a build slave

We are very happy to accept offers of build slaves! To run a build slave you'll need some additional software:

• Java (1.6 or later),
• git (1.7 or later),
• rvm

Ask on [email protected], and you'll get a user account. Then

• add a new node, labelling it with either 32bit or 64bit, and the OS - linux, windows, osx, freebsd, and so on.
• apt-get install openjdk-7-jdk cmake ruby1.9 zip unzip or equivalent
• 64 bit Linux users will need to apt-get install libc6:i386
• wget http://build.squeak.org/jnlpJars/slave.jar
• java -jar slave.jar -jnlpUrl http://build.squeak.org/computer/${SLAVENAME}/slave-agent.jnlp -jnlpCredentials username:password

To keep your slave persistently connected, you could always write a small upstart or systemd script to run Java.

What does what?

build_cog_vm.sh builds the Cog VM for the local platform. It assumes that another process has dumped a copy of the latest published VM source to its directory.

build_interpreter_vm.sh builds an interpreter VM for the local platform from the latest published source.

rake build prepares a test environment.

rake update_base_image takes an early 4.5 alpha image and updates it from trunk. It's a minimal image. ("Minimal" is more a description of what it should be, rather than what it is.)

rake test does what rake update_base_image does, and runs the full suite of SUnit tests on it. It produces Hudson/Jenkins compatible test reports. It should run on Linux, OS X, and Windows machines. FreeBSD support will follow as soon as some issues are resolved.

rake perf runs the performance tests in benchmarks.st, to allow Hudson to measure overall performance of the 4.5 image as it evolves.

rake release produces a 4.5 image suitable for release, labelled SqueakM.N-KKKK.image in a zipfile called Squeak4.5.zip. In particular, it loads several well-known packages.

resources\wallpaper.png contains the official background for the current Squeak release.

To run the tests for a particular package (find the currently supported packages in the package-load-tests directory) like this: rspec -fdoc --tag Xtreams test/package_test.rb.

How do I upgrade the Cog VM?

• Open up lib/squeak-ci/version.rb
• Edit COG_VERSION with the appropriate value. You can find the year & week portions of the version from the appropriate URL: http://www.mirandabanda.org/files/Cog/VM/VM.rNNNN/

Additional reading

If you run into any issues, please raise an issue here. If it looks like the issue's not a build in the scripts but a problem in building the VM, please mail [email protected] with details of your operating system and the output showing the problem.

While waiting for a reply, take a look the the official VM guides and see if you can solve the issue yourself. (If you do, please tell someone about it, either here as an issue, or in a post to the vm-dev list.)
