Some external functions I wish to call may take a long time and unnecessarily block other threads. This may lead to performance regressions for fast functions as releasing/acquiring the GVL is not cheap, but can improve performance for long-running functions in multi-threaded applications. This also means we must reacquire the GVL when calling Ruby-defined callbacks for Fiddle::Closure, meaning we must detect whether the current thread has the GVL by exporting ruby_thread_has_gvl_p in internal.h * ext/fiddle/function.c (struct nogvl_ffi_call_args): new struct for GVL release (nogvl_ffi_call): new function (function_call): adjust for GVL release [ruby-core:71642] [Feature #11607] * ext/fiddle/closure.c (struct callback_args): new struct for GVL acquire (with_gvl_callback): adjusted original callback function (callback): wrapper for conditional GVL acquire * ext/fiddle/depend: add dependencies * ext/fiddle/extconf.rb: include top_srcdir for internal.h * internal.h (ruby_thread_has_gvl_p): expose for fiddle * vm_core.h (ruby_thread_has_gvl_p): moved to internal.h * test/fiddle/test_function.rb (test_nogvl_poll): new test git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52723 b2dd03c8-39d4-4d8f-98ff-823fe69b080e |
