Magic, version 0.2.0.

Added

• Added Gemnasium, plus Coveralls and Code Climate integration (and hence improved code test coverage).
• Added functionality to handle releasing the GVL for any file and/or I/O operations.
• Added ability to Magic#flags_array to return name of each flag that is set.
• Added naïve synchronization via Mutex#lock and Mutex#unlock methods to make interactions with libmagic more thread-safe.
• Added ability for Travis CI test against multiple versions of vanilla libmagic.
• Added LLVM (clang) compiler to build with to Travis CI, and fixed various issues reported by clang compiler during build-time.
• Added ability for Magic#load to take nil as valid argument.
• Added support for the MAGIC_CONTINUE flag so that Magic#file, Magic#buffer and Magic#descriptor methods will return an array for multiple results when appropriate.
• Added rudimentary Vagrantfile that can be used to build a development environment.
• Added the Guard Ruby gem for convenience, with an appropriate Guardfile.

Changed

• Re-factored the API and cleaned up small portions of code and documentation.
• Changed Magic#version_array and Magic#version_string methods to be a singleton methods.
• Renamed the Magic#flags_array method to Magic#flags_to_a.
• Changed the Magic::new method, so that it accepts an array of paths from which to load the Magic database.
• Moved integration with File and String core classes into separate namespace.
• Changed the behaviour not to catch the generic Magic::Error, plus always to raise on errors coming from libmagic. This is to make it more aligned with the standard library, where file and I/O related errors would raise an appropriate exception.
• Changed behaviour consistent among various versions of libmagic adhering to the POSIX standard. This concerns the following IEEE 1003.1 standards:
  • http://pubs.opengroup.org/onlinepubs/007904975/utilities/file.html
  • http://pubs.opengroup.org/onlinepubs/9699919799/utilities/file.html

Fixed

• Fixed formatting and white spaces.
• Fixed Travis CI build against Rubinius.
• Fixed setting of global errno value to avoid race conditions.
• Fixed issue with libmagic's regular expression (regex) library not working with UTF-8 (or any other wide-character encoding).
• Fixed build to make it work with C++ compilers.
• Fixed any C90 standard related build-time warnings.
• Fixed version number to comply with Semantic Versioning 2 (http://semver.org/).

Deprecated

• Retired support for Ruby 1.8.x (no support for MRI, Ruby Enterprise Edition and Rubinius).
• Retired testing with Ruby 1.9.2 and 2.1.0, and added 2.2.0 on Travis CI.
• Removed forward declaration of errno as it's not needed on systems with modern C/C++ libraries and compilers.
• Removed the -Wl,--no-undefined option from LDFLAGS, as they might break on some systems.
