2020-11-18[ruby/fiddle] Add a "pinning" reference (#44)Aaron Patterson
* Add a "pinning" reference A `Fiddle::Pinned` objects will prevent the objects they point to from moving. This is useful in the case where you need to pass a reference to a C extension that keeps the address in a global and needs the address to be stable. For example: ```ruby class Foo A = "hi" # this is an embedded string some_c_function A # A might move! end ``` If `A` moves, then the underlying string buffer may also move. `Fiddle::Pinned` will prevent the object from moving: ```ruby class Foo A = "hi" # this is an embedded string A_pinner = Fiddle::Pinned.new(A) # :nodoc: some_c_function A # A can't move because of `Fiddle::Pinned` end ``` This is a similar strategy to what Graal uses: https://www.graalvm.org/sdk/javadoc/org/graalvm/nativeimage/PinnedObject.html#getObject-- * rename global to match exception name * Introduce generic Fiddle::Error and rearrange error classes Fiddle::Error is the generic exception base class for Fiddle exceptions. This commit introduces the class and rearranges Fiddle exceptions to inherit from it. https://github.com/ruby/fiddle/commit/ac52d00223 Notes: Merged: https://github.com/ruby/ruby/pull/3780
2020-11-18[ruby/fiddle] Add support for specifying types by name as String or SymbolSutou Kouhei
For example, :voidp equals to Fiddle::TYPE_VOID_P. https://github.com/ruby/fiddle/commit/3b4de54899 Notes: Merged: https://github.com/ruby/ruby/pull/3780
2020-11-18[ruby/fiddle] Add TYPE_CONST_STRING and SIZEOF_CONST_STRING for "const char *"Sutou Kouhei
Add rb_fiddle_ prefix to conversion functions.h to keep backward compatibility but value_to_generic() isn't safe for TYPE_CONST_STRING and not String src. Use rb_fiddle_value_to_generic() instead. https://github.com/ruby/fiddle/commit/0ffcaa39e5 Notes: Merged: https://github.com/ruby/ruby/pull/3780
