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>

2024-10-10Import JRuby implementation (#147)Sutou Kouhei
Fix GH-104 lib/fiddle/jruby.rb is based on https://github.com/jruby/jruby/blob/master/lib/ruby/stdlib/fiddle/jruby.rb . Here are changes for it: * Move `Fiddle::TYPE_*` to `Fiddle::Types::*` * Add `Fiddle::Types::VARIADIC` * Add `Fiddle::Types::CONST_STRING` * Add `Fiddle::Types::BOOL` * Add `Fiddle::Types::INT8_T` * Add `Fiddle::Types::UINT8_T` * Add `Fiddle::Types::INT16_T` * Add `Fiddle::Types::UINT16_T` * Add `Fiddle::Types::INT32_T` * Add `Fiddle::Types::UINT32_T` * Add `Fiddle::Types::INT64_T` * Add `Fiddle::Types::UINT64_T` * Add more `Fiddle::ALIGN_*` for the above new `Fiddle::Types::*` * Add more `Fiddle::SIZEOF_*` for the above new `Fiddle::Types::*` * Add support for specifying type as not only `Fiddle::Types::*` but also `Symbol` like `:int` * Add support for variable size arguments in `Fiddle::Function` * Add `Fiddle::Closure#free` * Add `Fiddle::Closure#freed?` * Add `Fiddle::Error` as base the error class * Add `Fiddle::Pointer#call_free` and stop using `FFI::AutoPointer` in `Fiddle::Pointer` * Add support for `Fiddle::Pointer.malloc {}` `Fiddle::Pointer` * Add support for `Fiddle::Pointer#free=` * Add `Fiddle::Pointer#freed?` * Use binary string not C string for `Fiddle::Pointer#[]` * Add `Fiddle::Handle.sym_defined?` * Add `Fiddle::Handle#sym_defined?` * Add `Fiddle::Handle::DEFAULT` * Add `Fiddle::ClearedReferenceError` * Add no-op `Fiddle::Pinned` Some features are still "not implemented". So there are some "omit"s for JRuby in tests. Notes: Merged: https://github.com/ruby/ruby/pull/11860

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>
