Building Rodin Headless

This page documents the procedure followed for building the binary packages of the Rodin platform that are distributed on SourceForge. The build is done in two steps

1. Fetch the sources from the repository and make a source archive with them.
2. Build the platform headless from this set of sources using Apache Ant.

Pre Build Verifications

Before building, several checks have to be made in the sources:

• clean build all RodinCore plug-ins, so that generated files are regenerated using repository sources
• JUnit tests are OK
• versions of plug-ins, features and product obey Eclipse versioning policy
• API Tooling build against previous Rodin release produces no errors on any plug-in
• the correct Eclipse version is referenced in the p2 configuration (org.rodinp.platform/p2.inf)
• branding plug-ins display the correct Eclipse version (text information found in several about.properties/plugin.properties files)
• SVN project org.rodinp.releng is up to date, i.e. all required plug-ins are listed/processed in
  • rodin-core.psf
  • rodin-tests.psf
  • customTargets.xml (copySources)
  • export-RodinCore-src-jars.xml
• documentation is up to date for /org.rodinp.platform/html/root.html
• generated documentation matches latest wiki sources for
  • /org.rodinp.keyboard/doc
• make a local test within Eclipse:
  • update buildId and buildVersion in org.rodinp.releng/build.properties
  • import (binary with linked content) org.eclipse.pde.build into the Eclipse workspace containing Rodin sources
  • run "Build Rodin Product.launch": if everything went well, a directory "${workspace_loc}/../work/result" contains zipped archives for every platform, else errors are reported in the console.

When everything works, any changes to the sources made during this verification process are pushed to the Source Forge repository.

Build Parameters

Several parameters need to be defined for each build:

1. the platform version, that is the user-visible version which is displayed in About Rodin Platform. Example of versions are 1.0 and 2.3RC1.
2. the Git commit number, which permits to know very precisely which source versions are used for the build.
3. the Git branch from which the commit can be checked out
4. the full platform version used for provisioning. This version is made of the platform version and the commit number, separated by a dot. Example of full versions are 2.8RC1.r365721c and 2.8.1.r6f52165.

Fetching Sources

Sources are fetched from Subversion using the script below. The script can be run on any Unix machine and takes the first two parameters described above (i.e., platform version and subversion revision). For instance, to build Rodin 1.1, the script was invoked as

fetchSources 1.1 7661

The script itself is

#!/bin/sh 
# 
#  Fetch sources of the Rodin Platform from the Subversion repository on 
#  SourceForge. 
# 
 
. ./version.sh 
 
GITROOT=ssh://pcb//git/c572/RodinCore.git 
 
fatal() { 
    echo "$@" >&2 
    exit 1 
} 
 
checkCommit() { 
    if expr "$GIT_COMMIT" : '^[0-9a-f][0-9a-f]*$' >/dev/null; then 
        : OK 
    else 
        fatal "Invalid GIT commit: $GIT_COMMIT" 
    fi 
} 
 
fetchSources() { 
    mkdir gitrepo || fatal "Some sources have already been checked out." 
    git clone --branch $GIT_BRANCH $GITROOT gitrepo 
    cd gitrepo 
    git checkout $GIT_COMMIT 
 
    mkdir ../sources 
    cp -R org.rodinp.releng ../sources 
 
    cat org.rodinp.releng/rodin-core.psf |  
    grep "^<project" | 
    sed -e 's/.*\,master\,//' -e 's/\".*//' | 
    xargs -i cp -R {} ../sources 
 
    cd .. 
} 
 
checkCommit 
fetchSources 
 
cd sources 
zip -q -r "../rodin-${VERSION}-sources.zip" *

Installing Eclipse for Headless Build

To install Eclipse for headless build, you first need to download two bundles from the Eclipse download site:

• eclipse-SDK-${VERSION}-${PLATFORM}.tar.gz
• eclipse-${VERSION}-delta-pack.zip

where VERSION is the version of Eclipse (e.g., 3.4.2) and PLATFORM specifies the host platform for the build (e.g., linux-gtk).

Once downloaded, you need to extract the first archive, and then the second archive on top of the first. You now have an Eclipse installation able to build binary distribution for all platforms supported by Eclipse.

Building the Platform

To build the platform, you just need to run the script below after possibly modifying some of the variables at the beginning of it. The meaning of the variables is

BUILD_ID	Simple platform version (first parameter above)
SVNREV	Subversion revision number with an r prepended
VERSION	Full platform version used for provisioning (must contain $SVNREV as qualifier)
JAVA_HOME	Absolute path to a Java Runtime Environment
BUILD_BASE	Absolute path to the directory used for building. As a result of a previous step, this directory must contain a sources folder where the Rodin sources have been downloaded.
ECLIPSE_HOME	Absolute path to the Eclipse installation (including the delta pack) to use for building
PDE_BUILD	Absolute path to the PDE plug-in in your Eclipse installation.
BASE_OS	Operating system of the host platform
BASE_WS	Windowing system of the host platform
BASE_ARCH	Architecture of the host platform

The build script is

#!/bin/sh

BUILD_ID=2.8 
GIT_COMMIT=05788b6 
GIT_BRANCH=2.8-master

Post Build Verifications

When the build worked, the "work/result" directory contains zipped archives for all platforms. For each of them, check that:

• "rodin" binary is an executable file (for Linux and Mac)
• a directory "dropins" exists at the root (under "rodin", among "features", plugins", ...)
• in "configuration/org.eclipse.equinox.simpleconfigurator/bundles.info", plug-in "org.eclipse.equinox.p2.reconciler.dropins" is configured with auto start mode ("true" at the end of the line)

Failures must be manually corrected. Final archives shall match the above requirements.

Providing Sources

Sources must also be provided, in both these ways:

• compressed source archive, as fetched through #Fetching Sources
• archive suitable for inclusion in a target platform (see Generating source bundles for inclusion in a target platform configuration)
• SVN tag under /svnroot/rodin-b-sharp/tags/RodinCore/x.y

Last operations to perform

• Ensure that the download of the uploaded version of Rodin is here by default
• Update the main wiki page:
  • http://wiki.event-b.org/index.php/Main_Page
  • The image "out now" is to be changed
  • The link "learn more" should point to the release notes
  • The link "download now" should point to the SF repository
• The Platform releases page should be updated:
  • http://wiki.event-b.org/index.php/Rodin_Platform_Releases
• The 64 bits page should be updated:
  • http://wiki.event-b.org/index.php/Rodin_64_bit
• A group for the new release is available on Bug and Feature Request trackers.
• A mail is sent on the user + announce rodin SF lists.
