Add support for Ruby 2.7; Fix code generated for Ruby global variables
2020-01-23 15:29:48 +00:00
From 00e291b319bd6b58bf061feee3721a58c9c6be32 Mon Sep 17 00:00:00 2001
From: Thomas Reitmayr <treitmayr@devbase.at>

Subject: [PATCH] Add support for Ruby 2.7
This commit fixes the signatures of various callback methods
and cleans up the macro definitions used for casting callbacks.
Note that the transparent version of the macro RUBY_METHOD_FUNC
is currently masked behind RUBY_DEVEL, see commit
https://github.com/ruby/ruby/commit/1d91feaf13e0ffe04b2dabc6e77e4101b6d0bb07
In order to still support strict signature checking and prevent
nasty deprecation warnings, the use of RUBY_METHOD_FUNC had to
be replaced with VALUEFUNC.
