X-BeenThere: ruby-core@ruby-lang.org X-Mailman-Version: 2.1.15 Precedence: list Reply-To: Ruby developers List-Id: Ruby developers List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: ruby-core-bounces@ruby-lang.org Sender: "ruby-core" Issue #17643 has been updated by cfis (Charlie Savage). @nobu - Sorry that I missed your feedback. I updated the code to call ruby_options, but that just hangs the interpreter. It thinks it is going to run a ruby script, but that is not correct. I have attached a screenshot of the call stack. What I want to do is initialize the interpreter so I can later run code in it. As part of the initialization I'd like to set GC.stress to true. I updated the embedding code to look like this (copied from Ruby's main function): ```c int argc = 0; char* argv = nullptr; char** pArgv = &argv; ruby_sysinit(&argc, &pArgv); { RUBY_INIT_STACK; ruby_init(); ruby_run_node(ruby_options(argc, pArgv)); } initialized__ = true; // <----- this is never called ``` That doesn't work. Could you point me in the direction of what does work? Thanks! ---------------------------------------- Bug #17643: Ruby 3 embedded - no GC methods? https://bugs.ruby-lang.org/issues/17643#change-91245 * Author: cfis (Charlie Savage) * Status: Rejected * Priority: Normal * Assignee: nobu (Nobuyoshi Nakada) * ruby -v: ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x64-mingw32] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- The following code works on Ruby 2.x, but not on Ruby 3.0.0. ``` c // Initialize Ruby VM int argc = 0; char* argv = (char*)malloc(1); argv[0] = 0; char** pArgv = &argv; ruby_sysinit(&argc, &pArgv); ruby_init(); ruby_init_loadpath(); // Try to call GC.start int state; VALUE result = rb_eval_string_protect("GC.start", &state); VALUE err = rb_errinfo(); VALUE rubyMessage = rb_funcall(err, rb_intern("message"), 0); char* message = RSTRING_PTR(rubyMessage); message is "undefined method `start' for GC:Module" ``` This is true for all the GC methods (stop, stress, etc). Note if you create a Ruby script that contains GC.start and run it using the Ruby interpreter all is well. Is there some new special way Ruby 3 needs to be embedded? Note I tested this on mingw, MSVC and gcc (Fedora). All the same. Like I said above, this code works fine on Ruby 2.7 and earlier. -- https://bugs.ruby-lang.org/
