* Implement the last missing Write Barriers and dsizeJean Boussier2023-03-061-3/+11
| | | | | | | | | | | | | | Ref: https://github.com/ffi/ffi/pull/991 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. It's not counting everything because some types are opaque right now, so a larger refactoring would be needed.

This commit also implement a `dsize` function so that these instance report a more relevant size in various memory profilers. It's not counting everything because some types are opaque right now, so a larger refactoring would be needed. While I was at it, I moved `Symbol.library` into the unused `Symbol.base.rbParent` which seemed appropriate and saves a pointer.

* Convert FFI::DynamicLibrary to TypedDataLars Kanis2023-03-031-7/+19
| | | | | | | Ref: ffi#991 The old untyped DATA API is soft deprecated and this new one open the door to write barriers, compaction, memsize etc.

* Remove win32/stdint.h and stdbool.hLars Kanis2020-09-231-6/+1
| | | | | | | | Only very old Visual-C compilers before 2010 didn't contain these files. Since the copyright of the included files conflicts with ffi's license, we better remove it. Fixes #693
* Remove taint supportyuuji.yaginuma2019-11-251-1/+1
| | | | | | | | | | Ruby 2.7 deprecates taint and it no longer has an effect. https://bugs.ruby-lang.org/issues/16131 The APIs related to taint cause deprecation warning message and the lack of taint support should not cause a problem in previous Ruby versions. So I removed that. But if need to taint support that to old versions of Ruby, I will update PR.

* Avoid undefined behaviour of LoadLibrary() on Windows.Lars Kanis2017-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | According to [1] the flag LOAD_WITH_ALTERED_SEARCH_PATH should be used with absolute paths only. It has the effect, that the path of the DLL to be loaded is temporary added to the search path, so that dependent DLLs in the same directory can be found and loaded implicit. However for relative paths the standard LoadLibrary() search order should be used, because the behaviour of LOAD_WITH_ALTERED_SEARCH_PATH isn't defined for relative paths. In practice (on Windows 10) relative paths to Windows system DLLs do work, so that the library is loaded, but DLLs in other search paths are not found, when this flag is set. Ruby's fiddle library uses LoadLibrary without flags in both cases. [1] https://msdn.microsoft.com/en-us/library/windows/desktop/ms684179(v=vs.85).aspx
