Version 2.1.2 - PHP 7 `Throwable` exception compatibility

Features

• PHP 7 Throwables will now properly be caught and sent up the exception handling chain.
• Expanded compatibility with other exception types in some method signatures

Bug fixes

• Broad exception catch statements will now properly handle PHP 7 Throwable types

Upgrading

Interface Changes

• The RoutePathCompilationException::createFromRoute() method signature has changed to allow both Exception and Throwable types with dual support for PHP 5 and PHP 7
• The 4th parameter to the callbacks supported by Klein#onError will now be able to receive Throwable types under PHP 7

Version 2.1.1 - PHP 7 and HHVM compatibility

Features

• Header keys are now normalized, by default, to their canonical MIME format for consistency
• Header key normalization is now customizable
• Internal callback data-structures were moved from arrays to more appropriate SplQueue and SplStack instances, providing performance and memory footprint improvements
• The PHPUnit version used for tests has been updated for HHVM compatibility
• PHP 7.0 and HHVM compatibility!

Bug fixes

• A few internal property/attribute names have been updated for consistency
• An iteration bug effecting tests run under certain HHVM runtime versions has been fixed
• The README document has been updated to fix a few errors
• The file() method in the Response class has been updated to fix an issue found when run under PHP-FPM
• The file() method in the Response class will no longer send the Content-Length header when the response has been chunked, to comply with the HTTP requirements defined in RFC 2616
• References to the old https://github.com/chriso/klein.php repository URL have been updated to the new repository URL home of Klein: https://github.com/klein/klein.php
• Tests were updated to pass under an expanded number of PHP runtime versions and configurations
• A potential output buffer stack miss-handling in the dispatch process has been fixed

Upgrading

Deprecations

• The HeaderDataCollection::normalizeName() method has been deprecated in favor of using new normalization options (via constant switches) and other more specific methods on the same class

Interface Changes

• Three of the Klein internal callback attributes have changed both name and data structure. These attributes are protected, so the effect will only be felt by users that have extended and/or overwritten Klein's internal behaviors. The following changes were made:
  • Klein#errorCallbacks was renamed to Klein#error_callbacks and it's array data-structure was changed to use an SplStack
  • Klein#httpErrorCallbacks was renamed to Klein#http_error_callbacks and it's array data-structure was changed to use an SplStack
  • Klein#afterFilterCallbacks was renamed to Klein#after_filter_callbacks and it's array data-structure was changed to use an SplQueue
• Validator#defaultAdded was renamed to Validator#default_added

Version 2.1.0! This is quite a big release...

Features

• New exception and helper methods to help control the dispatch flow
• New abort() method to allow stopping the routing process and returning a response code
• Routes are now instances of a new Route class, instead of just being a set of meta properties and a callback
• Routes are now stored in a RouteCollection class, which extends the DataCollection class
• New keys() and clear() methods for the DataCollection class
• Added the capability of reverse routing!
• Now allowing for route callbacks to change the response object by returning a new ApiResponse instance
• New "slug" type for route param matching
• New isEmpty() and cloneEmpty() methods for the DataCollection class
• The $matched route callback parameter is now an instance of a RouteCollection, instead of just an integer
• Route callbacks are now passed the Klein instance for easier closure/class-scope use
• Regular expression routing is now more accurate and will match more special characters in a similar way to Sinatra
• Routes are now built with a dependency injected AbstractRouteFactory instance, allowing the building of routes to be customized more easily
• New options() and head() alias methods for matching OPTIONS and HEAD requests respectively
• The Response class has been abstracted into an AbstractResponse and a separate Response class for cleaner 3rd-party extension
• New "after dispatch" callbacks can be registered for firing a series of callbacks after the dispatch loop has completed
• New patch() alias method for matching PATCH requests
• New HTTP error handling via exceptions and callback registration for a more direct (and less magical) API for controlling HTTP errors
• The escape() method in the ServiceProvider class now allows for the passing of entity escaping flags
• Route regular expressions are now validated and provide helpful errors upon a validation failure
• Routes can now contain an empty string path
• The composer autoloader is now compatible with the PSR-4 standard.
• Regular expression compilation performance has been improved
• 100% Code Coverage

Bug fixes

• The README document has been updated to fix a few typos and inconsistencies
• Route params are now properly URL decoded
• 404/405 routes now properly set the appropriate status code automatically
• Silencing the locked response exceptions as the behavior is designed to be transparent/automatic
• Allow route callables to be an array suitable for call_user_func() callable behavior
• More proper handling for 404's that also call the 404 error handlers
• The file() and json() methods in the Response class no longer override system-configured time processing limits
• Now checking if the output buffer is open before attempting to close it
• The methods matched counter ($methods_matched) is now much more accurate, not counting methods that shouldn't have been considered matches
• Various PHPdoc inaccuracies and inconsistencies have been fixed
• Regular expressions are now quoted during compilation in a much safer manner
• The PHPdoc tags have been updated to use the more modern syntax

Upgrading

Deprecations

• Handling 404 and 405 errors with a specially registered route callback is now deprecated. It's now suggested to use Klein's new onHttpError() method instead.
• Autoloading the library with Composer no longer utilizes the PSR-0 spec. The composer autoloader now uses PSR-4.

Interface Changes

• Some of the route callback params have changed. This will effect any route definitions with callbacks using the more advanced parameters.
  • The old params were (in order):
    • Request $request
    • Response $response
    • Service $service
    • App $app
    • int $matched
    • array $methods_matched
  • The new params are (in order):
    • Request $request
    • Response $response
    • Service $service
    • App $app
    • Klein $klein
    • RouteCollection $matched
    • array $methods_matched
• Non-match routes (routes that are wildcard and shouldn't consider as "matches") will no longer be considered as part of the "methods matched" array, since they aren't supposed to be matches in the first place
  • This may have implications for users that have created "match-all" OPTIONS method routes, as the OPTIONS method will no longer be considered a match.
  • If you'd like to conserve the old match behavior, you can simply mark the route as one that should be counted as a match with $route->setCountMatch(true)
