Grails Diary - Week 10 in 2014

10 March 2014

This week has offered both a new Grails release, of version 2.3.7, a bugfix release of version 2.2.5, and the first milestone release of Grails 2.4.0, which uses Groovy 2.2 and Spring-framework 4. The 2.3.7 version has issues with the Hibernate plugin it ships with, for multiple datasources and providers like Mongo, so it is recommended to upgrade it to":hibernate:3.6.10.10"

Cédric Champeau is working on Traits for Groovy, and you are encouraged to test and review, on the open pull request

Peter Ledbrook promotes a discussion on the mailing list, about correct use of HTTP status codes: http://grails.1312388.n4.nabble.com/REST-status-codes-td4654080.html

The description of the bug in the resources plugin, which causes information disclosure, is updated with more information on mitigation strategies: CVE-2014-0053

Should blocks in Spock tests be indented? Zan Trash started an interesting discussion on twitter.

In another twitter thread, Ted Naleid has started working on a pre-built way to compile js files with replaceable values for the asset-pipeline plugin. He has recently submitted the groovy-template-grails-asset-pipeline plugin.

I'll be at Greach in the end of March. Catch me if you have comments or suggestions for the Grails Diary, or just wish to chat :)

The redis-plugin plugin also provides the possibility to set a TTL for a cached entry (using the provided @Memoize annotation), but it lacks the option to serialize any kind of Serializable objects (only object ids are cached and then hydrated from main DB). This means ...
