[dependabot-preview]

Bumps rack-contrib from 1.8.0 to 2.2.0.

Release notes

Sourced from rack-contrib's releases.

Stuck at home? Why not release your favourite collection of Rack contributions!

A healthy crop of fixes and new features in this release. Thanks to everyone who contributed, and welcome to Andrew Konchin, as the newest recipient of a commit bit.

• New middleware Rack::JSONBodyParser: a better-designed replacement for Rack::PostBodyContentTypeParser, with a more appropriate name (given that they both only handle JSON natively, having JSON in the name seems like a good idea), and with a better set of default behaviours and knobs. It is also significantly faster than PostBodyContentTypeParser.

• Rack::PostBodyContentTypeParser: this middleware's interface is a bit of a mess, which makes it nearly impossible to improve in a backwards-compatible manner. As a result, its use has been deprecated, in favour of Rack::JSONBodyParser.

• Several middlewares that set Content-Length headers were fixed to use String#bytesize, instead of String#size, which makes multibyte characters much happier. (Chris Frank)

• Rack::ResponseCache: Make header detection case-insensitive. (Chris Frank)

• A lot of broken tests and deprecation warnings in the test suite were fixed. (Andrew Konchin)

• Rack::Locale: significant correctness fixes, including q=0 handling, case insensitivity where appropriate, and better handling of whitespace. (Andrew Konchin)

• Rack::StaticCache: several correctness fixes, such as setting a Date response header, use UTC in timestamps, and improving the robustness of the date rendering.

Share and enjoy!

Spring has sprung so let's make a new release

New features:

• Rack::PostBodyContentTypeParser -- you can now pass a block to the middleware to override the default "parse me some JSON" behaviour. Thanks to Kris Dekeyser (@Kris-LEBIS) for the patch.

• Ruby 2.5 support -- we're now running the test suite through Ruby 2.5.1, as well as the latest patch releases of all other Ruby releases supported by rack-contrib (back to 2.2, the same as Rack itself). The only "interesting" change here is that some Rack::Profiler printers no longer work, which is not our fault, but rather a problem with ruby-prof.
