Beta 1

[Tal Liron]

Happy 2014

Prudence and Sincerity are now in beta. Please distribute the news widely!

FULLY DOCUMENTED

The Prudence Manual manual is now *finished*, which means that everything that I consider necessary for using Prudence 2.0 is now confirmed to be existing and working. Are there bugs? Probably, so that's where you come in ... please help test and report bugs, even if they are documentation bugs.

Exciting teasers:

• Learn how to implement a super-scalable task farm in the cluster chapter
• MVC on Prudence: it's possible, and there are even working examples for using Jinja2 templates or StringTemplate
• See how to execute live code in the debugging chapter
  
• Load-balancing: fully explained with Nginx and Perlbal examples in the deployment chapter

What are you waiting for? Start with the Tutorial, and expand your horizons from there. Or go ahead and print the 160-page (!) PDF.

JVM 8 NOW

The entire stack now supports JVM 8 via the current developer release of OpenJDK, and will be using Nashorn by default (falling back to Rhino for JVM 7 and earlier). Simple benchmarking has revealed significant performance gains -- I will publish some information about it soon. Please help testing by running the stack on JVM 8! Lots of effort has been put into making sure everything works with Nashorn, from plugins to the MongoDB API. The Three Crickets web site has also moved to using JVM 8.

LOGGING

One major shift in this release is upgrading the logging plugin to use Log4j 2.0. This upgrade represents a major reworking of Log4j, with exciting performance improvements due to its use of the Disruptor library, and it also includes no-SQL appenders. Log4j 2.0 is still in beta, and in integrating it into Sincerity I've discovered and reported quite a few bugs. For now, they are implemented with workarounds, so everything should "just work" as long as you're using Sincerity.

For you, this means that you need to redo your logging configuration -- the scripts now all use a Sincerity.Log4j library, which makes everything easier on your end.

PRUDENCE 2.0-beta1

Breaking change in how internal requests are handled: please use the "application/internal" MIME type instead of "application/java". The Prudence Manual explains this: http://staging.threecrickets.com/prudence/manual/internal/#avoiding-serialization-for-internal-requests

Congrats Tal! Your work is truly inspiring and thank you for making it available to all.

Now I just need an app to write!

On a side note - I was recently looking into lua and found luaj. The top result when i google luaj, jetty and jsr223 is your bug report and what the associated fix is. Ha! Looks like a new luaj came out yesterday. Not sure if your fix is in though... Thanks again for your work.
