2024-12-16[ruby/fiddle] ffi_backend: convert numeric function args to pointersDani Smith
(https://github.com/ruby/fiddle/pull/162) This allows for passing integers as pointer arguments to functions when using the FFI backend. This is a workaround until we can get JRuby's FFI implementation to allow for it directly (see also https://github.com/jruby/jruby/pull/8423) --------- https://github.com/ruby/fiddle/commit/e2f0952e9b Co-authored-by: Benoit Daloze <eregontp@gmail.com>

omitted on Fedora 40 aarch64 (https://github.com/ruby/fiddle/pull/161) I found working on Fedora 40 on aarch64 that `test_dlopen_linker_script_input_linux` was omitted due to not finding libncurses.so, since it is in /usr/lib64.

2023-06-28[ruby/fiddle] Add a helper method for reading/writing memoryAaron Patterson
(https://github.com/ruby/fiddle/pull/123) This commit adds two new methods, `Fiddle::Pointer.read` and `Fiddle::Pointer.write`. Both methods take an address, and will read or write bytes at that address respectively. For example we can read from an address without making a Pointer object: ```ruby Fiddle::Pointer.read(address, 5) # read 5 bytes ``` We can also write to an address without allocating a Pointer object: ```ruby Fiddle::Pointer.write(address, "bytes") # write 5 bytes ``` This allows us to read / write memory at arbitrary addresses without instantiating a new `Fiddle::Pointer` object. Examples where this API would be useful [1](https://github.com/tenderlove/tenderjit/blob/f03481d28bff4d248746e596929b0841de65f181/lib/tenderjit/fiddle_hacks.rb#L26-L28) [2](https://github.com/tenderlove/ruby/blob/77c8daa2d40dd58eeb3785ce17dea2ee38f308d1/lib/ruby_vm/rjit/c_pointer.rb#L193) [3](https://github.com/tenderlove/ruby/blob/77c8daa2d40dd58eeb3785ce17dea2ee38f308d1/lib/ruby_vm/rjit/c_pointer.rb#L284) I also added a writer method for the same reasons as the reader. --------- https://github.com/ruby/fiddle/commit/04238cefed Co-authored-by: Sutou Kouhei <kou@clear-code.com>

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>
