Padrino 0.13.0 - Mustermann Router, Performance Enhancements, Streaming Support, and Much More

Posted on October 12, 2015 by Nathan Esquenazi | categories: ruby, update

Padrino 0.12.4 was shipped on October 19th 2014. Hard to believe that just about a year has flown by since then as we have been working towards our next major release of Padrino. While there have been betas available for some time, we are excited to announce the final release of Padrino 0.13.0! This version has a huge host of improvements and upgrades, both big and small.

This 0.13.0 release brings several major changes and updates including a completely redesigned router, significant performance enhancements, streaming support, bug fixes and a ton of code cleanup. Full details for this release are below. You should also check out the 0.13.0 upgrade guide as well for a detailed look at moving up from 0.12.X.

Redesigned Mustermann Router

One of the big changes in this release was the retirement of http_router which is no longer being maintained. We have switched to a brand new router written by @namusyaka. The older router had accrued significant technical debt with many hacks and workarounds introduced along with thread-safety issues. We’ve been working on this redesigned router for quite sometime, running router benchmarks and making sure we took our time to ensure a smooth replacement. We are proud to unveil the new router with this release and you can read more details in this PR.

Project-wide Configuration

With 0.13.0 comes project-wide global configuration options with environment support. This is inspired by the Sinatra configuration system but is project-wide rather than app-specific. Configuration can be done anywhere in your project including config/apps.rb:

Padrino.config.value1 = 42

Padrino.configure :development do |config|
  config.value2 = "only development"
end

Padrino.configure :development, :production do |config|
  config.value2 = "both development and production"
end

Padrino.configure do |config|
  config.value2 = "any environment"
end

and then these values can be accessed with:

Padrino.config.value1 # => 42
Padrino.config.value2 # => 'any environment'

Thanks to @ujifgc for implementing this. More details can be found in the PR.

Sinatra Upgrades

In this release, we have upgraded Sinatra to the latest 1.4.6 release which allowed us to clean up several previous workarounds. The result is an even cleaner integration with Sinatra. This includes the following Sinatra compatibility improvements:

We are committed to compatibility with our Sinatra core and this release marks a solid step forward in that regard.

Component Updates

There are several component updates and tweaks in this release including but not limited to:

Performance Improvements

We are committed to making Padrino as lightweight and comparable to raw Sinatra speed as possible. In that vein, we have made the following improvements:

We’ve also introduced a benchmark test suite to test speed for padrino core and router:

This should help us in making continued improvements going forward.
