* [ruby/fiddle] Add "offsetof" to Struct classes ↵Aaron Patterson2021-07-131-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (https://github.com/ruby/fiddle/pull/83) * Add "offsetof" to Struct classes I need to get the offset of a member inside a struct without allocating the struct. This patch adds an "offsetof" class method to structs that are generated. The usage is like this: ```ruby MyStruct = struct [ "int64_t i", "char c", ] MyStruct.offsetof("i") # => 0 MyStruct.offsetof("c") # => 8 ``` * Update test/fiddle/test_c_struct_builder.rb Co-authored-by: Sutou Kouhei <kou@cozmixng.org> https://github.com/ruby/fiddle/commit/4e3b60c5b6 Co-authored-by: Sutou Kouhei <kou@cozmixng.org>

* Revert "test/fiddle/helper.rb: remove duplication (#3863)" (#3865)Kenta Murata2020-12-081-1/+5
| | | | | | This reverts commit bd47a8d660ab33a20c5e28d0effcc29105c434e4. `libc_so` and `libm_so` are `nil` at line 124 because Big Sur doesn't have `/usr/lib/libSystem.B.dylib`. The reassignment at line 127 is necessary in this case.

* [ruby/fiddle] Add a "pinning" reference (#44)Aaron Patterson2020-11-181-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* [ruby/fiddle] Add support for specifying types by name as String or SymbolSutou Kouhei2020-11-181-13/+13
| | | | | | For example, :voidp equals to Fiddle::TYPE_VOID_P. https://github.com/ruby/fiddle/commit/3b4de54899
* [ruby/fiddle] Add TYPE_CONST_STRING and SIZEOF_CONST_STRING for "const char *"Sutou Kouhei2020-11-182-9/+27
| | | | | | | | 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

|
* Use libSystem.dylib instead of libm.dylib and libc.dylibHiroshi SHIBATA2020-09-081-2/+1
| | | | Because macOS 11.0(Big Sur) was removed libc and libm from `/usr/lib`.
