[ruby-core:119239] [Ruby master Feature#20750] Expose ruby_thread_has_gvl_p in ruby/thread.h

Issue #20750 has been updated by Eregon (Benoit Daloze). Note that the majority of the search results are just CRuby using it, and GitHub not detecting it's effectively copies of CRuby. This seems like a strange pattern, why not just use `rb_thread_call_with_gvl` and remove the condition? That should be as efficient and not need to rely on private APIs. ---------------------------------------- Feature #20750: Expose ruby_thread_has_gvl_p in ruby/thread.h https://bugs.ruby-lang.org/issues/20750#change-109822 * Author: kbrock (Keenan Brock) * Status: Open ---------------------------------------- Hello All, I'm hoping we can make `ruby_thread_has_gvl_p` a public method and no longer experimental.

Issue #20750 has been updated by kbrock (Keenan Brock). Hello Benoit, Thank you for your question. Eregon (Benoit Daloze) wrote in #note-1:

Yes, agreed. The pattern seems overly verbose and complicated. It is part of a gem's PR to get ruby 3.3 working [1] To determine if this is strange, I went looking for how other code calls `rb_thread_call_with_gvl`. ## Patterns I searched for `rb_thread_call_with_gvl` to see the various calling patterns. [2] ### ffi In ffi, they make the `ruby_thread_has_gvl_p` check in the 1 method call to `rb_thread_call_with_gvl` [3] ### ruby using `rb_thread_call_with_gvl` In ruby, it seems checking `ruby_thread_has_gvl_p` before calling `rb_thread_call_with_gvl` is a very common use case. [4] [5] [6] Of note, ruby has one other pattern: Define methods specific to the case that the gvl is not acquired. (Though some of these examples like [7] may just be asserting the gvl is obtained) ### ruby using `ruby_thread_has_gvl_p` It is almost as if `ruby_thread_has_gvl_p` is only used for 2 purposes: - Decide to use or not use `rb_thread_call_with_gvl` (our use case). - `VM_ASSERT(ruby_thread_has_gvl_p())` - an extension of specific methods for gvl acquired. ### conclusion To me, it seems this pattern is valid. Agreed that it would be nice if the code were organized better and it partitioned whether the gvl has already been acquired. Are there other patterns I missed?

Issue #20750 has been updated by Eregon (Benoit Daloze). So what is the concrete issue if the pattern above is replaced by `rb_thread_call_with_gvl(method_call, &context);`? Does `rb_thread_call_with_gvl()` fail if the GVL is already acquired? If so, I think that would be a bug of `rb_thread_call_with_gvl()` and it should be fixed. From the name it seems pretty clear it should just call the callback if the GVL is already acquired. ---------------------------------------- Feature #20750: Expose ruby_thread_has_gvl_p in ruby/thread.h https://bugs.ruby-lang.org/issues/20750#change-109833 * Author: kbrock (Keenan Brock) * Status: Open ---------------------------------------- Hello All, I'm hoping we can make `ruby_thread_has_gvl_p` a public method and no longer experimental.

Issue #20750 has been updated by Eregon (Benoit Daloze). OK the issue/bug is https://github.com/ruby/ruby/blob/4797b0704ae49fb42c8ad9a45028efbe2298b5f5/t... ``` if (brb == 0) { rb_bug("rb_thread_call_with_gvl: called by a thread which has GVL."); } ``` @ko1 I think that's a bug, I think rb_thread_call_with_gvl() should be allowed if the GVL is already acquired, there seems to be no value to prevent it. TruffleRuby already implements those semantics BTW.

Issue #20750 has been updated by kbrock (Keenan Brock). Benoit, Thank you. Maybe I should have run the more complete pattern that I see in the ruby code base: ```c if(!ruby_native_thread_p()) { // (th = ruby_thread_from_native()) == 0 //issues else if(ruby_thread_has_gvl_p()) { // (brb = th->blocking_region_buffer) == 0 func(params); } else { rb_thread_call_with_gvl(func, params); } ``` I had not wanted to be intrusive, but I think this solution makes much more sense. ---------------------------------------- Feature #20750: Expose ruby_thread_has_gvl_p in ruby/thread.h https://bugs.ruby-lang.org/issues/20750#change-109849 * Author: kbrock (Keenan Brock) * Status: Open ---------------------------------------- Hello All, I'm hoping we can make `ruby_thread_has_gvl_p` a public method and no longer experimental.

I'm hoping we can make `ruby_thread_has_gvl_p` a public method and no longer experimental.
This has been done as part of #20877 in https://github.com/ruby/ruby/pull/11975/commits/979c05185270d088b4531a65aac1... ---------------------------------------- Feature #20750: Allow rb_thread_call_with_gvl to work when thread already has GVL https://bugs.ruby-lang.org/issues/20750#change-115261 * Author: kbrock (Keenan Brock) * Status: Open ---------------------------------------- Hello All, I'm hoping we can make `ruby_thread_has_gvl_p` a public method and no longer experimental. I saw the following code in a gem that was not compiling with ruby 3.3: ``` c // int ruby_thread_has_gvl_p(void); // <== line of concern if (ruby_thread_has_gvl_p()) { method_call(&context); } else { rb_thread_call_with_gvl(method_call, &context); } ``` 400 unique projects on github added the line listed above to fix compilation. [1] Some of the projects detected the method first in `extconf.rb`, but a majority just referenced it. `ffi` used to have the detection code but dropped it since the method was in all supported ruby versions. It feels like this method is now part of the undocumented public interface. My suggestion is to add the method to the real public interface in `ruby/thread.h`.
