Snaps is a prototype also from dm Server where it was known as Slices. It aims to give you the full benefit of a dynamic and modular OSGi environment for your web applications by allowing you to spread the front end across many bundles, or Snaps. The Snaps source code is available from one of our Git repos listed on the 'Source' tab. Thanks to Patsy Phelan and Dmitry Sklyut for comments on this content.
+
 
+
A Snap is an OSGi Web Application Bundle that is responsible for handling requests for part of the total application. Requests are served up to each snap depending on what part of the context path the snap has registered to handle. Each Snap will be given requests by a host bundle. A Host bundle is also just a normal web application bundle with filter configured to dispatch certain requests to any registered Snaps.
+
 
+
&nbsp; [[Image:Snaps.png]]
+
 
+
The host will handle requests to '/app/*' while '/app/orders' and '/app/billing' will be dispatched to the relevant Snap bundle.  
+
 
+
Snaps is different from other technologies such as Web Fragments in that it much more decoupled and takes advantage of OSGi to allow for the dynamic composition of a web app at runtime. The lifecycle of the Snap and the Host is completely decoupled. This is due to the services like approach. Web Fragments are static and much more closely coupled, they share the same classpath and the modularity it offers is only at development time. This extra decoupling means that snaps can be developed in isolation from the host application, even after the host application has be released.

This page summarises the Virgo plan and notes design ideas for future Virgo features.

Virgo Plan

The following plan is subject to change and depends on how much resource is available as the project evolves.

4.0.0 (Cobalt) Release

  • Upgrade to Gemini Management 2.0
  • Support Equinox unity (my suggestion, it may now be called something different) - see bug 404390

3.8.0 Release

See the Bugs addressed for 3.8.0 for more information.

3.7.2 Release

  • Upgrade to Gemini Web 3.0 (Embedded Apache Tomcat 8.5.16)

See the Bugs addressed for 3.7.2 for more information.

3.7.1 Release

  • Upgrade to Gemini Blueprint 2.1
  • Upgrade to Spring Framework 4.3.9
  • Upgrade to Jolokia 1.3.6
  • Upgrade to commons-io 2.5
  • Upgrade to Logback 1.2.3
  • Upgrade to Slf4j 1.7.25
  • Deliver OkHttp3 Bundles with Virgo

See the Bugs fixed with 3.7.1 for more information.

3.7.0 (Steel) Release

  • Upgrade to Gemini Blueprint 2.0
  • Upgrade to Gemini Web 3.0 (Embedded Apache Tomcat 8.5.11)
  • TBD, but see the Steel bugtrain bug 396813.

Release Branding

To accommodate simultaneous releases of Virgo runtime, OSGi Web Container runtime, and Virgo tooling, we are branding each release with the name of a colour, including old releases.

Fern SpringSource dm Server 1.0.x Embedded Apache Tomcat 6.0.x Spring DM 1.1.x 2.5.6.A - -

Gemini Blueprint 2.0 4.2.x.RELEASE Gemini Management 1.0.5 Virgo IDE 1.5
Cobalt Virgo 4.0 Gemini Web 3.0.x
(Embedded Apache Tomcat 8.5.x)
Gemini Blueprint 2.0 4.2.x.RELEASE Gemini Management 2.0 Virgo IDE 1.6

Note 1: we are steering clear of the following "wimp list" of colours: Azure, Indigo.


Future Directions

Support for the OSGi Subsystems specification is deferred indefinitely (rationale), except for generalising the InstallArtifact tree to a DAG which was implemented in Virgo 3.5.0 (see the Kernel Enhancements section of the Virgo 3.5.0 release notes).
