Andy Schwartz commented on TRINIDAD-2234:
-----------------------------------------
I have implemented a solution that exposes a skin pregeneration service via an
internal view. Requests into this internal view cause skin pregeneration to
kick in.
The new API is fairly small:
- A couple of system properties for enabling this service.
- The internal view name.
- Request parameters for tweaking pregeneration behavior.
I will upload a patch shortly and provide more details on the
design/implementation.
> Pregeneration of skin style sheets
> ----------------------------------
>
> Key: TRINIDAD-2234
> URL: https://issues.apache.org/jira/browse/TRINIDAD-2234
> Project: MyFaces Trinidad
> Issue Type: New Feature
> Components: Skinning
> Affects Versions: 2.0.1-core
> Reporter: Andy Schwartz
> Assignee: Andy Schwartz
> Priority: Minor
>
> Trinidad skinning dynamically generates style sheets at runtime to meet
> context-specific (ie. platform/agent/locale/accessibility-specific) skinning
> requirements. While dynamic generation of style sheets is beneficial in that
> it allows fine tuning of which styles are delivered for particular contexts,
> it can complicate some use cases.
> One case that dynamic generation makes particularly difficult is where the
> application and its resources are split across separate hosts/domains. In
> this case, resources are typically hosted on a dedicated server that can be:
> a) Shared across multiple applications, thus improving the likelihood of
> browser cache hits. And...
> b) More easily fronted by a CDN (without also having to route all application
> traffic through a CDN ).
> Since a single skin definition can result in an arbitrary number of generated
> style sheets, it is not possible to host Trinidad skin/style sheets on a
> dedicated server - ie. there is currently no reliable way to pre-generate all
> possible variants of any given skin.
> This issue requests that we add a new skin pregeneration feature that would
> allow all style sheet variants for any skin to be generated prior to
> application deployment. This would facilitate the the split
> application/resources scenario described above.
