So you are interested in the provisioning code. Great! There are several levels of involvement ranging from calling the API to contributing provisioning code. This page should help you understand how to do all of those. If you are actually looking to get started as an end-user of the provisioning facilities then check out the getting started guide for users.
Getting the code
- Get the most recent 3.5 build available (http://download.eclipse.org/eclipse/downloads/)
- Create a CVS repository location for ":pserver:anonymous@dev.eclipse.org:/cvsroot/rt". Hint: Select the quoted text, open the CVS Repositories view, and select Paste Connection or hit Ctrl+V to add the connection
- Expand HEAD > org.eclipse.equinox > p2
- Checkout "org.eclipse.equinox.p2.releng"
- Import the "projectSet.psf" project set by right clicking on the file in the Package Explorer and clicking Import Project Set... in the releng project you just checked out. If you are a committer, and able to make an extssh connection, you can use projectSet-extssh.psf
You will get a mess of projects added to you workspace and you are "good to go".
Understanding the code
While it would be extremely hard to capture essence of all the different code areas here, we can give you a few starting points and places to look.
- The Equinox p2 Concepts document sets out much of the terminology for and relationships between the different elements of the Equinox provisioning system.
- ProvisioningHelper in the console bundle. This is a helper class that has lots of useful methods and is useful as an example of how to do various operations. Note that this class is currently not API and is sadly misplaced to be widely useful (in the console bundle?!), but overall, it is very educational.
- Also it worth nothing that the code you check out contains two kinds of bundles. First are the runtime bundles (you will deploy a subset of those when you want to use p2 as a provisioning system, e.g. engine, director, etc.), second are the bundles related to tooling (e.g. publisher, metadata.generator, repo tools, etc.).
My first run
Note that there are also a bunch of launch configurations that come in the various projects. We can't explain them all here but looking at the launch configs (and the code they run) is one interesting starting point. To get a feel for how things work the section below walks you through using a few of the launch configs to setup a working provisioning system.
- director app This allows you to run the director application, which is a headless way to install and uninstall using p2. http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclipse.platform.doc.isv/guide/p2_director.html
- Publisher * This allows you to generate p2 metadata from various input
