2022-10-07[ruby/fiddle] Add Fiddle::Closure.create and Fiddle::Closure.freeSutou Kouhei
GitHub: fix GH-102 It's for freeing a closure explicitly. We can't use Fiddle::Closure before we fork the process. If we do it, the process may be crashed with SELinux.

2022-10-07[ruby/fiddle] Add `sym_defined?` methods to test if a symbol is defined ↵Aaron Patterson
(https://github.com/ruby/fiddle/pull/108) I would like to check if a symbol is defined before trying to access it. Some symbols aren't available on all platforms, so instead of raising an exception, I want to check if it's defined first. Today we have to do: ```ruby begin addr = Fiddle::Handle.sym("something") # do something rescue Fiddle::DLError end ``` I want to write this: ```ruby if Fiddle::Handle.sym_defined?("something") addr = Fiddle::Handle.sym("something") # do something end ``` https://github.com/ruby/fiddle/commit/9d3371de13 Co-authored-by: Sutou Kouhei <kou@clear-code.com>
2022-10-07[ruby/fiddle] Move "type" constants to `Fiddle::Types` ↵Aaron Patterson
(https://github.com/ruby/fiddle/pull/112) This helps to reduce repetition in code. Instead of doing "TYPE_*" everywhere, you can do `include Fiddle::Types`, and write the type name directly. This PR is to help reduce repetition when writing Fiddle code. Right now we have to type `TYPE_` everywhere, and you also have to include all of `Fiddle` to access `TYPE_*` constants. With this change, you can just include `Fiddle::Types` and it will shorten your code and also you only have to include those constants. Here is an example before: ```ruby require "fiddle" module MMAP # All Fiddle constants included include Fiddle def self.make_function name, args, ret ptr = Handle::DEFAULT[name] func = Function.new ptr, args, ret, name: name define_singleton_method name, &func.to_proc end make_function "munmap", [TYPE_VOIDP, # addr TYPE_SIZE_T], # len TYPE_INT make_function "mmap", [TYPE_VOIDP, TYPE_SIZE_T, TYPE_INT, TYPE_INT, TYPE_INT, TYPE_INT], TYPE_VOIDP make_function "mprotect", [TYPE_VOIDP, TYPE_SIZE_T, TYPE_INT], TYPE_INT end ``` After: ```ruby require "fiddle" module MMAP # Only type names included include Fiddle::Types def self.make_function name, args, ret ptr = Fiddle::Handle::DEFAULT[name] func = Fiddle::Function.new ptr, args, ret, name: name define_singleton_method name, &func.to_proc end make_function "munmap", [VOIDP, # addr SIZE_T], # len INT make_function "mmap", [VOIDP, SIZE_T, INT, INT, INT, INT], VOIDP make_function "mprotect", [VOIDP, SIZE_T, INT], INT end ``` We only need to import the type names, and you don't have to type `TYPE_` over and over. I think this makes Fiddle code easier to read. https://github.com/ruby/fiddle/commit/49fa7233e5 Co-authored-by: Sutou Kouhei <kou@clear-code.com>
2022-10-07[ruby/fiddle] Add constants for unsigned values ↵Aaron Patterson
(https://github.com/ruby/fiddle/pull/111) This commit adds constants for unsigned values. Currently we can use `-` to mean "unsigned", but I think having a specific name makes Fiddle more user friendly. This commit continues to support `-`, but introduces negative constants with "unsigned" names I think this will help to eliminate [this code](https://github.com/ruby/ruby/blob/3a56bf0bcc66e14ffe5ec89efc32ecfceed180f4/lib/mjit/c_type.rb#L31-L38) https://github.com/ruby/fiddle/commit/2bef0f1082 Co-authored-by: Sutou Kouhei <kou@clear-code.com>

(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.

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. Notes: Merged-By: mrkn <mrkn@ruby-lang.org>

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

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
