  • What about you? • How do you use p2? • What are you looking to get out of this tutorial? • Are your building products based on p2? Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Agile Software Development • Key characteristic of agile software development includes Fast Cycle Time: • Include your customers in the development process • Ensure your customers are continually using the latest software • Ensure your developers are building against the latest software Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Overview • How can p2 be used to manage your update strategy? • Update your RCP and OSGi applications • Provide a mechanism to install and manage new features • Provide a mechanism to manage different configurations • Manage your developers target platforms Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Outline • Overview of p2 • p2 architecture and terminology • Anatomy of a repository • Using the director and publisher • Product based builds with p2 • Repository management best practices • Assembling products out of pre-existing components (no compiling) Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Hands-on exercises • Building and assembling different configurations of your application • Building and publishing add-on bundles • Export or build your product to a repository, and then install the product from the repository you just created. • Using repository tools such as the slicer, repo2runnable or mirror to build smaller components from existing repositories Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • A brief history of Eclipse • When Eclipse starts, the plug-ins are scanned and functionality is discovered • If a dependency is missing, all the dependent plug-ins simply fail to start • Old plug-ins pollute the application • You cannot update resources, licenses, executables or the framework itself Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Unzipping is not Installing Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • What is p2 – p2 is Installing! • A replacement for the old update manager • New UI, simplified workflow • Manage Eclipse, RCP and more (exe, ini, bundles, registry keys, …) • Shared bundles across Eclipse-based products • An installer TM • A provisioning platform for OSGi systems (in progress) • Managing non-running instance • Start level, framework extension • Fine-grained dependency management Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • What does p2 enable? • An extensible provisioning platform for OSGiTM systems which provides • Installation • Searching for updates • Rollback • Dependency management • Policy control • UI or headless Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • What p2 isn’t • An end to end build system • PDE build provides tooling to generate p2 repositories when building bundles • A product – the eclipse community builds the products! Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • What can you build with p2? • Add-on manager for RCP applications • Installers • Configuration Management Systems • Self updating applications • Install -> Update -> Roll back scenarios • etc… Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Who needs to provision? Engineers Users source code applications open source tools in-house built runtimes licensed software Automated Builds Test Test Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • p2 is for more than just bundles • p2 can provision • OSGiTM bundles • Executables • Configuration files – for instance eclipse.ini and config.ini • Registry keys • Native code • Also supports bundle pooling – sharing bundles across multiple installs Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Where’s p2 ? Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • p2 terminology • Artifacts is actual content being installed (bytes) • Metadata consist of Installable units (IUs) that describes the content that can be installed Person Artifact IU Name: org.eclipse.gumby Version:3.6.0.v20100321 Requirements: org.eclipse.pokey Provided capabilities: org.eclipse.bendy Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Decouple decision making from the actual content IU (id, ver) Everything is an IU Everything is installable It is also referred to as “metadata” Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Anatomy of an IU, more • Update description • This allows to control of • IU is being updated org.eclipse.osgi_3.5.1 _v20090827 • IU to update it to org.eclipse.osgi_3.5.2_v20100126 • Applicability filter • This allows for an IU to express when it is only applicable to a particular environment. • Example platform specific filters for swt fragments (x86,linux,gtk) Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Anatomy of an IU, requirements / capabilities • Capabilities and requirements are the mechanism by which an IU express what it provides and what needs. • A capability is composed of a: • Namespace (string), name (string) and version • A requirement is composed of a query by default: • Namespace, name and version range • Namespace, name and version are open ended. • The requirements and capabilities expressed by IUs can be arbitrary and don’t have to all be in the same namespace. • Resources – RPMs, .exes, docs, … • Virtual – if you can define a capability, I can depend on it Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Separation of concerns • Installable Unit • Exists independently of the repository • Metadata Repository • Store only Installable Units • Artifact Repository • Store only Artifacts Metadata Artifacts Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Artifacts • Bytes/content to be installed • Any form • JARs (e.g., bundles, features, …)‫‏‬ • Binary executables • RPM, MSI, … • Defined, maintained, loaded and used separately from the metadata Copyright © IBM Corp., EclipseSource 2010. All rights reserved. Licensed under EPL, v1.0.
  • Repositories • Defined as an interface, IRepository • No serialization format assumed • All repositories have • Identity • Version • Description • Repos can be queried • Allows for delayed loading • Captures standard questions Copyright © IBM Corp., EclipseSource 2010.
