Cutelyst 0.5.0

A bit more than one year after the initial commit, Cutelyst makes it's 5th release. It's now powering 3 commercial applications, the last one recently got into production and is the most complex of them, making heavy use of Grantlee and Cutelyst capabilities. Speaking of Grantlee if you use it on Qt5 you will get hit by QTBUG-41469 which sadly doesn't seems to get fixed in time for 5.4, but uWSGI can constrain your application resources so your server doesn't go out of memory (worth the leak due to it's usefulness). Here is an overview since 0.4.0 release:

  • Remove hardcode build setting to "Debug", so that one can build with "Release" increasing performance up to 20% - https://gitorious.org/cutelyst/pages/CutelystPerformance
  • Request::uploads() API was changed to be useful in real world, filling a QMap with the form field name as a key and in the proper order sent by the client
  • Introduced a new C_ATTR macro which allows to have the same Perl attributs syntax like C_ATTR(method_name, :Path(/foo/bar) :Args)
  • Added an Action class RoleACL which allows for doing authorization on control lists, making it easy to deny access to some resources if a user doesn't match the needed role
  • Added a RenderView class to make it easier to delegate the rendering to a view such as Grantlee
  • Request class is now QObject class so that we can use it on Grantlee as ctx.request.something
  • Make use of uWSGI ini (--init) configuration file to also configure the Cutelyst application
  • Better docs
  • As always some bugs were fixed

I'm very happy with the results, all those site performance tools like webpagetest give great scores for the apps, and I have started to work on translating Catalyst tutorial to Cutelyst, but I realize that I need Chained dispatcher working before that... If you want to try it, I've made a hello-world app available today at https://gitorious.org/cutelyst/hello-world Download here!
