| * | Freeze immutable objects and add explicit make_shareable to make library ↵Lars Kanis2023-05-075-19/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | definitions Ractor usable Freeze objects which are immutable from the start are now freezed. This allows these objects to be used by Ractor without make_shareable. This partially reverts commit 4fc6a8c5ec8a9a720330946af9d1103015c62942 in such a way, that functions are stored in a module variable @ffi_functions. Enums are implemented per FFI::Library not per attached function. To make them shareable they would have to be copied and freezed per function. This would increase memory footprint for the sake of Ractor support. IMHO it's better to mark the module explicit as finished by .freeze to allow its use in a Ractor. This also enables querying the enum definitions from a Ractor. Using a Hash instead of per-function variables allow to use foo! and bar? methods as wished in #971. Fixes #971
| * | Rename result_type to return_typeLars Kanis2023-04-271-2/+2
| | | | | | | | | | | | | | | The term "return_type" is already used in Truffleruby and sounds better to me. On the other hand the term "result_type" was only used in C-ffi as FunctionInfo#result_type, which is an internal class only.
| * | Store each FFI::Function in it's own instance variabe in the module to be ↵Lars Kanis2023-04-272-20/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | attached This allows to freeze the FFI::Function immediately, so that it is shareable by Ractor without the need to freeze the module explicit. To make it shareable the typedef hash used for variadic functions is duplicated and made frozen. This creates a small compatibility issue: Only typedefs defined above the variadic function can be used by that function. If a typedef is created after the definition of the variadic function, then this typedef can no longer be used as parameter to that variadic function. Also fix the retrieval of simple (non-struct) global variables per #attached_variables. Closes #975

| * | Freeze global typedefs and add per Ractor local custom typedefsLars Kanis2023-04-181-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ractor-local custom typedefs are used now, since global writable typedefs aren't compatible with Ractor isolation. Now the builtin typedefs are frozen and available for all Ractors. But all custom typedefs are only per Ractor. Actually the global typedefs already were useable in Ractors, if they are resolved in C code. This is because the C code doesn't check the Ractor boundaries.
| * | Add support for using FFI in RactorLars Kanis2023-04-184-1/+46
| | | | | | | | | | | | | | | | | | | | | | | | All objects are shareable now when frozen. All objects can be created in a non-main Ractor. Typedefs are a global mutable state and are not accessable from Ractor other than the main Ractor. So all Function, Struct, etc. must be defined in the main Ractor and can then be used in other Ractors.
* | | Allow private release method for ManagedStruct and AutoPointerLars Kanis2023-05-022-21/+5
| | | | | | | | | | | | | | | | | | | | | | | | FFI users might not want to expose `release` as a public class method, but want to keep it private. Also re-enable GC tests that were disabled as part of #427, but make them opt-in per env var FFI_TEST_GC. Derivations of Releaser are no longer necessary, so that they are removed now.

* | Implement Write Barrier and dsize for FFI::StructLayoutJean Boussier2023-03-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | And FFI::StructLayout::Field Write barrier protected objects are allowed to be promoted to the old generation, which means they only get marked on major GC. The downside is that the RB_BJ_WRITE macro MUST be used to set references, otherwise the referenced object may be garbaged collected. This commit also implement a `dsize` function so that these instance report a more relevant size in various memory profilers. I had to get rid of the `memset(0)` in `struct_layout_mark` has with Write Barriers it's not guaranteed that the layout will be marked before `fieldName` is moved. I don't think it was a good fix anyway, it's better to mark these VALUE so the GC pin them. I think we could go back to an `st_table` and mark only the keys with `rb_mark_set`. But I didn't want to go down this rabbit hole.
