Provisioning UI Overview

There are currently two flavors of provisioning UI under development. To complicate matters, you can configure your workspace to run both at the same time if you desire.

• The end user UI appears as a new menu item Software Updates (Incubation)... in the help menu of your eclipse application. To include this UI in your eclipse application, you want to include the plug-in org.eclipse.equinox.prov.ui.sdk in your launch.
• The admin UI appears as either a perspective in your Eclipse launch, or as a stand-alone RCP app. The intention of this UI is to help the team develop, test, and use the provisioning infrastructure. Thus the UI exposes the underlying infrastructure and associated terminology to the end user, which is definitely not the approach we expect to take for end users. To include this UI, you want to include the plug-in org.eclipse.equinox.prov.ui.admin in your launch, or else run the RCP version of the app using the launch in org.eclipse.equinox.prov.ui.admin.rcp.
• Note that if you enable the sdk UI in a launch of the admin UI, you can operate the admin UI and still launch the end-user UI using the menu item in the help menu. If you do this, you will notice multiple property pages for repositories and IU's, one with developer/implementation info, and the other with more end-user info.

Plugin Structure

• org.eclipse.equinox.prov.ui contains code we think is useful for any SWT/JFace-based provisioning UI.
  • Content and label providers for showing provisioning objects in views
  • View filtering
  • Widget groups for creating/editing provisioning objects
  • Common drag/drop adapters with pluggable prompting
  • Reusable actions and operations for provisioning commands
  • Pluggable update and install UI
  • Issues not addressed yet
    • Evolve the current undo support to use the underlying engine history, not UI-level implementation
    • Scalability issues - lazy content providers for repo access (iteration vs. collection)
    • consider UI forms vs. dialogs
    • Input validators for provisioning info (repo URLs, capabilities, touchpoint types, etc.)
    • Automatic checking for available updates with pluggable notification style
• org.eclipse.equinox.prov.ui.sdk contains the update manager replacement UI. You'll see terminology such as "feature" and "site" used in this UI.
• org.eclipse.equinox.prov.ui.admin is the current developer/administrator UI.
• org.eclipse.equinox.prov.ui.rcp is an RCP application of the admin UI

Eclipse SDK UI

Different workflows drive the development of this UI. The first priority is to deliver the equivalent functionality of the current Update Manager UI. Note that we are not saying we are solving all of these problems. Part of defining the workflow may be saying that we aren't addressing it yet.

• User is looking for a specific software component to add to their environment
  • Simple install
    • user browses repositories for software to install/update
    • UI precomputes info such as required software, download size/time, etc
    • user accepts licenses, etc.
  • Install requires updating (or downgrading) of existing components
  • Conflicts arise in the requirements for various components
• Software updating
  • User looks for updates of software already installed
  • User wants automatic checking/notification of available updates
  • Silent/automatic updating
• User wants to remove a software component from their environment
  • Simple uninstall
  • Associated uninstall of required software
  • How much does the user care about complete rollback (downgrading components that were upgraded by an install, etc.)
• User wants to know what software is available for download (browse, search by function or name, etc.)
• User's environment is defined explicitly by someone external (administrator)
  • Upgrade or install to a new specification
  • Compare current installation to required one
• User wants to return to some previously known state (rollback to a named state)

Admin UI

The following are improvements for the admin UI

• General UI polish issues
  • persisting user choices (view expansions, etc.)
  • more flexible work flows (create a new profile from profile chooser, etc.)
  • configurable label providers to control what is seen in various views

Milestone plan

      • [done]Detect invalid states on install/update/uninstall
    • Polling for software updates and associated user prefs
      • Automatic updating
      • Alert me when updates available
      • Ability to update now/remind me later
    • Improved support for browsing repos
      • IU categories
      • Filtering of available IU view
  • Admin UI
    • Artifact repo view shows artifact descriptors, processing steps, size, etc.

Additional Requirements

Here are some requirements that have surfaced so far. They are not added in a milestone plan yet.

• Use engine query infrastructure for content providers (lazy population of views) Bug 203543
• UI for rollback Bug 205223

  • Core can call a UI service that can prompt for certain types (file, dir, numbers, etc.)
• Improved way to present licenses and remember accepted licenses Bug 205232
• Installation by drag and drop on a running eclipse
• Ability to update to a new version of a base and keep other plug-ins
• Ability to install from other eclipse installs on the machine
• Install from a click on the webpage
• Silent installation
• Support installation even when there are errors in the configuration
• Admin/tooling
  • Repo management
    • Create and populate repos
    • Category definition
  • Defining and persisting profiles for mass deployment to users

Past milestone plans

• M2
  • Install, Uninstall, and/or update IU's from running profile
    • user views installed IU's in the current profile
    • user can manage repositories as an advanced feature (separate button on dialog)
      • repositories are colocated (no distinction between metadata and artifact repo)
    • UI prequalifies the install
      • figure out if the install is valid using oracle
      • [deferred] use advanced oracle to flag any invalid states
      • [deferred] use advanced oracle to precompute info such as download size/time, etc.
    • user can uninstall an installed IU
    • user can update an installed IU
  • Repository naming
    • repo level
    • [deferred] user can override repo name

    • Give the ability to name what is being installed
  • Admin UI can launch end user UI from selected profile in profile view
