Progress Report

May 1, 2012: Prudence 2.0-dev1

The most significant changes in 2.0 have been in packaging and distribution. No longer are there "flavors": instead, language support is installed via modules managed by Sincerity. The directory structure has also changed. Additionally, JavaScript is now the default language used for application bootstrapping/configuration.

• Implicit resources: new feature (multilingual dispatch mechanisms)
• Merged /web/dynamic/, /web/static/, /resources/ into /mapped/
• API: removed filter and filterBase
• Prudence JavaScript Library: new!
• Bootstrapping, logging, service/daemon: removed! We now using Sincerity instead
• Distribution: moved to the Three Crickets Repository
• Version control: switched from Subversion to git
• Build: we now use Ivy to download dependencies required for compiling the Java source code
• Prudence Manual: heavily restructured for all the above

• Distribution: an informative readme.txt is now included, with instructions on installation and troubleshooting (issue #11)
• Distribution: make sure all text files are in Windows-friendly format (CR-LF line ending)
• Distribution: cleaner packaging of jQuery, now also including the license

Mar 26, 2011: Prudence 1.1-RC2 (revision 916)

Bugs fixed:

• NPE in ResolvingTemplate when used outside of applications (for example, in tasks)
• Clojure flavor: code was commented out by mistake
• Windows: run.bat script was not enumerating the jars

New features:

• New API: application.distributedTask
• New API: application.distributedGlobals
• New API: conversation.disposition
• New API: document.context (for /tasks/)
• /resources/: can now return binary data (as byte arrays)
• /tasks/: improved exception handling

• /tasks/: can now be called over Hazelcast
• Comment scriptlets, via <%# ... %> (via Scripturian)
• Dependency bumps: Hazelcast 1.9.2.2, H2 1.3.153, Scripturian R261, MongoDB driver 2.5.2, Commons Daemon 1.0.5

Mar 5, 2011: Prudence 1.1-RC1 (revision 886)

Bugs fixed:

• Concurrency bugs: DelegatedHandler (used by filters and cache key pattern handlers)
• document.internal does now follow same capturing route exposed externally
• {dn} variable is truncated in cache key patterns for relative paths
• conversation.stop logs an error
• conversation.internal can be wrong for some captured requests

New features:

• "/libraries/javascript/" automatically added to library path (with equivalents for other languages)
• Support for multiple library locations (also improved performance for access to libraries)
• Delegated filters can now capture, allowing for some very powerful filters
• New API: application.sharedGlobals (with matching predefinedSharedGlobals in the configuration scripts)
• New router APIs: reattach, capture with/without query
• Settings: a single minimumTimeBetweenValidityChecks replaces all variants
• Concurrency improvements: DelegatedResource, GeneratedTextResource, Fallback, FallbackRouter
• Dependency bumps: Restlet 2.0.5, Jython 2.5.2
• Rhino: higher optimization level
• Restlet utilities: support for overriding default Resolvers (allows supporting new template variables; currently we're not using this)

Many parts of the routing, attribute setup, and configuration script code have been rewritten. One consequence is that the new recommended best practice is to always standardize on using a beginning slash for all internal URIs (router.capture, document.execute, document.include, document.internal). The Prudence Manual and all example applications have been updated accordingly.
