The latest version of Apple Push Notifications on Rails (APN on Rails) has been released. This release brings a few bug fixes, a new migration, and Feedback processing.

Installing/upgrading is easy:

$ sudo gem install apn_on_rails
$ ruby script/generate apn_migrations
$ rake db:migrate


It’s important to always run the migrations generator after each update to get the latest database schema needed for the the gem.

To use the new Feedback integration you have to first make sure that you update the new last_registered_at column when your iPhone application calls home. This column is checked against the timestamp Apple returns with the device token. If the last_registered_at is older than Apple’s date then the device is deleted, otherwise the Feedback is ignored.

To get and process the list of devices from Apple’s Feedback service just run the following Rake task:

$ rake apn:feedback:process

Enjoy!

Thanks to the cold and snowy New England winter this year, I’ve been able to devote quite a bit of time to getting Mack to run on Ruby 1.9, so with that said, here’s the 0.8.3 release of Mack, featuring… TADA… Ruby 1.9!! Of course there are a few other features and improvements in this release. Here’s a quick run down:

Ruby 1.9

The big one. Mack runs very well on Ruby 1.9, unfortunately I can’t say the same thing about some other frameworks. I’ve had some run ins with DataMapper on 1.9, but I’m sure those will be ironed out shortly.

A few weeks ago I announced I was working on getting Ruby 1.9 support for all my gems and libraries. I started out with Configatron, then upgraded Cachetastic and Genosaurus. Now Mack is 1.9 compatible. When I made the announcement the guys at RailsEnvy picked up on it and said that I made a call to arms to the community to pick up 1.9 support. Now granted, I didn’t actually say those words, but I think the intent was there, so I’m going to now officially say those words. This is a ‘call to arms’ to the Ruby community to upgrade their gems, plugins, libraries, frameworks, etc… to work on Ruby 1.9. I’ve done it, and I can tell you, it’s not that tough. Just use multiruby, and you’re off and running.

ActiveSupport In, Facets Out

What with the world getting smaller these days, well, at least the world of Ruby web frameworks. A lot of great work is going into refactoring ActiveSupport and making it faster, better, and smaller. Because of that and the fact that every time a new release of Facets comes out it breaks a whole lot of stuff, I’ve decided to use ActiveSupport as the basis of the mack-facets gem. So basically mack-facets is just ActiveSupport with a few more enhancements.

JavaScript Effects

Thanks to the tireless efforts of Gerardo Pis-Lopez, mack-javascript, has been upgraded to add helpers methods for effects for both Prototype/Scriptaculous and jQuery. Thank you to Gerardo for the much needed upgraded to mack-javascript.

Upgrades

Mack has been upgraded to use Rack 0.9.1, DataMapper 0.9.9, and a few other smaller gems.

Changelog:

• [#243] Upgraded to Rack 0.9.1
• [#242] Upgraded to DataMapper 0.9.9
• [#241] Removed dependency on Facets
• [#239] Add do_sqlite3 to gems.rb
• [#166] Effects for mack-javascript
• [#133] Added Form Builders
• [#22] Ruby 1.9 Support
• gem: rack 0.9.1
• gem: rspec 1.1.12
• gem: configatron 2.2.2
• gem: cachetastic 2.1.2
• gem: data_mapper 0.9.9
• gem: addressable 2.0.1
• gem: extlib 0.9.9

Happy New Year everyone!

With the help of the absolutely amazing multiruby library and an edge version of rspec from GitHub, the latest version of Configatron now supports JRuby 1.1.6 and Ruby 1.9.1rc1. There are no other functional changes to the library, so it’s a full drop in replacement for vesion 2.1.6.

I highly encourage everyone to checkout multiruby and start upgrading their libraries so we can all move to 1.9 quicker, which means more speed and more power. Once we’re all in 1.9 land we can really make use of some of the amazing features it provides.

Anyway, I’ll be working on upgrading all my libraries and applications to work on 1.8 and 1.9, and hopefully JRuby, over the next couple of months. So be on the look out for a new versions of Cachetastic, Genosaurus [update: Genosaurus already works with 1.9 and JRuby. Hoorah!], and, of course, Mack.

Hey there folks, sorry for the long wait for this release, but it’s here. It’s been a long November for yours truly. I’ve had to find a new job. I’ve had pneumonia. We, at least in America, have celebrated Thanksgiving. And, of course, who can forget RubyConf 2008?

So with that said, what’s in 0.8.2? Honestly, not a whole lot. There are a couple of bug fixes, a button_to_remote (think submit_to_remote in Rails) helper, and deferred routes. More on deferred routes in a moment, as it’s actually a pretty cool feature that only Mack and Merb share. And finally there is bundled gems.

Bundled Gems

What do I mean I say ‘bundled gems’? Well, because of the rather large number of gems that get installed with Mack, and because of some gem version dependency issues, Mack is now bundling it’s third party dependency gems inside itself. For example, mack-facets used to rely on the gems ‘facets’ and ‘english’. Those gems are now bundled inside the mack-facets gem and now longer need to be downloaded and installed by end users. This should make installing Mack super easy. It should also make dealing with having multiple versions of Mack installed on your system easier to deal with and maintain.

Deferred? Routes

So what are deferred routes? Ezra wrote a really great write up back in April. The idea is simple, with newer web servers such as Thin and Ebb, you can tell them to spawn a new thread to handle particular requests, such as long running processes like file uploads. This can really help speed things up as server can process regular requests using an event machine model, which is very fast, but can be really slow and block the server for longer processes. Now those processes can spawn into their own threads and not block the server.

In Mack 0.8.2 you can mark your routes with a deferred? => true option which will trigger this behavior. It’s much more advanced than the similar feature that can be found in Merb, which requires a separate configuration for your deferred actions, and the urls have to be ‘hard coded’. Mack let’s you use all the dynamic power of your routes, like you would want to. It’s just another option on the route itself.

Thanks to Matthew A. Brown for his contribution to the Configatron library. He added the ability to ‘lock’ down a namespace. Configatron has had a protect method for a while, but that only locks down a specific configuration. With lock you can lock down the whole namespace and prevent everything in that namespace from being altered. Maybe some code will help you understand:
