2024-04-26Allow RUBY_GC_LIBRARY_PATH to be set in minirubyPeter Zhu
miniruby is used by tool/runruby.rb, so we need to ensure we don't rb_bug when RUBY_GC_LIBRARY_PATH is set so we can run tests using the make commands. This commit changes it to warn instead.
2024-04-24Pass string error buffer into dln_openPeter Zhu
On Windows, the error exists on the stack so we should pass an error buffer from the caller.
2024-04-23Get error from dln_open when USE_SHARED_GCPeter Zhu
Before, if dln_open failed to open RUBY_GC_LIBRARY_PATH, it would segfault because it would try to raise an error, which cannot happen because the GC has not been initialized yet. This commit changes dln_open to return the error that occurred so the caller can handle the error.

It is for dynamically loading, useless for statically linked objects.
2023-12-19[wasm] dln.c: Guard `dladdr` use in symbol incompatibility checkYuta Saito
wasi-libc recently added a family of `dl*` functions[^1], but it still doesn't have `dladdr` unlike other platforms. Guard the use of `dladdr` with `HAVE_DLADDR` to avoid build failure with the head version of wasi-libc. The library name is used only for diagnostic purpose if it's not NULL, so it's safe to skip it. [^1]: https://github.com/WebAssembly/wasi-libc/commit/b85d65528d6e17ae1874c6cc6a6a3ac02e83021a
2023-12-14rb_ext_resolve_symbol: C API to resolve and return externed symbols [Feature ↵Satoshi Tagomori
#20005] This is a C API for extensions to resolve and get function symbols of other extensions. Extensions can check the expected symbol is correctly loaded and accessible, and use it if it is available. Otherwise, extensions can raise their own error to guide users to setup their environments correctly and what's missing.
2023-12-14dln_symbol: make dln_sym accessible Ruby internallySatoshi Tagomori
The symbol resolved by dln_symbol will eventually be passed to extensions. The error handling of dln_sym is also separated into dln_sym_func because the new call resolving symbols will not raise LoadError.

2022-02-22[Feature #18249] Implement ABI checkingPeter Zhu
Header file include/ruby/internal/abi.h contains RUBY_ABI_VERSION which is the ABI version. This value should be bumped whenever an ABI incompatible change is introduced. When loading dynamic libraries, Ruby will compare its own `ruby_abi_version` and the `ruby_abi_version` of the loaded library. If these two values don't match it will raise a `LoadError`. This feature can also be turned off by setting the environment variable `RUBY_RUBY_ABI_CHECK=0`. This feature will prevent cases where previously installed native gems fail in unexpected ways due to incompatibility of changes in header files. This will force the developer to recompile their gems to use the same header files as the built Ruby. In Ruby, the ABI version is exposed through `RbConfig::CONFIG["ruby_abi_version"]`.

Function pointers are not void*. See also ce4ea956d24eab5089a143bba38126f2b11b55b6 8427fca49bd85205f5a8766292dd893f003c0e48
2019-12-26decouple internal.h headers卜部昌平
Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).
