This page lays out milestone plans for the development of the Equinox Provisioning system (p2) in Eclipse 3.4.

Plan

M1 - August 2, 2007

Goals:

• Operations supported: install, uninstall, update, rollback.
• Self provisioning from a small download of the agent
• The agent runs in process

Details:

• Director / metadata:
  • Implement groups and selectors
  • Define constraints descriptors
  • Refine how fragments are being attached

• Engine:
  • Define new phases and operations.

• UI:
  • Browse what's installed in a profile
  • Invoke operations
  • Browse a repository

• First run integration: ability to ship metadata / artifact repo / profile with eclipse
• Investigate shared install problems

M2 - September 21, 2007

Goals:

• Updating the running profile (self update with a reasonable UI)
• Support for update / rollback in the director
• Support for transaction in the engine

Details:

• Director / metadata:
  • Implement groups and selectors
  • Refine and implement constraints descriptors

• Engine:
  • Support for transaction

• UI:
  • End user UI to install and update
  • Presentation of metadata repo content to the user

• Misc
  • Move to ECF 1.0.2
  • Support for relative paths
  • Review the usage of framework admin:
    • How are we using it?
    • Why do we use it, what does it bring?
  • Discover the JRE being used to run

• Shared install:
  • Initial implementation

• Repository:
  • Support for filtering content presented to the user
  • Make the artifact repository writable and have support for post-processing
  • Have an artifact repository implementation to read update sites

M3 - November 2, 2007

• Establish concrete set of functionality to be available in 3.4 final
• Perform rename of bundles and packages to the new name: p2. Updating wiki pages and other documents accordingly (dj)
• True self hosting:
  • Produce regular I-builds and nightly builds of p2 bundles (Kim/DJ)
  • p2 team will update across I-builds using p2 (all)
  • PDE target provisioning from bundles.txt
• Cross-platform:
  • Build the agent for all platforms (dj)
  • Metadata generation for all platforms (dj)
  • Be able to install to any platform/os from a single update site
• Engine:
  • Transaction support across phases
• Integrate metadata generation with current build update site generation (dj)
• Polish end-user UI work flows (Susan)
• Shared install (AndrewO, Tim)
• Pluggable download manager strategy (Tim)
• ECF support for pause/resume (Scott)
• ECF support for introspecting transports (throughput, latency) (Scott)
• Review Framework admin API, and usage of Framework admin in p2

M4 - December 14, 2007

M5 - February 8, 2008

Pending Items

If you are looking to be involved, feel free to pick any item listed below.

Questions:

• Nested profiles - multiple products installed together but run independently
• Prerequisites
• Governor - What does the governor look like?
• Installer - what does the installer look like?
• Branding experience for install
• Installing into the agent (customizing installer)
• Resolver - can't backtrack, do we need a new resolver algorithm?
• Metadata shape
  • Uses
  • Advice (aka recommendations)
  • Signatures/authentication for metadata

New items:
