fiddle: release GVL for ffi_call
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
