From 680f0b5ba4eb4ba4f542ebc8d1204da61b71eb92 Mon Sep 17 00:00:00 2001 From: ko1 Date: Mon, 27 May 2013 00:21:02 +0000 Subject: * include/ruby/ruby.h, gc.c, vm_trace.c: add internal events. * RUBY_INTERNAL_EVENT_NEWOBJ: object created. * RUBY_INTERNAL_EVENT_FREE: object freeed. * RUBY_INTERNAL_EVENT_GC_START: GC started. And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'. Internal events can not invoke any Ruby program because the tracing timing may be critical (under huge restriction). These events can be hooked only by C-extensions. We recommend to use rb_potponed_job_register() API to call Ruby program safely. This change is mostly written by Aman Gupta (tmm1). https://bugs.ruby-lang.org/issues/8107#note-12 [Feature #8107] * include/ruby/debug.h, vm_trace.c: added two new APIs. * rb_tracearg_event_flag() returns rb_event_flag_t of this event. * rb_tracearg_object() returns created/freeed object. * ext/-test-/tracepoint/extconf.rb, ext/-test-/tracepoint/tracepoint.c, test/-ext-/tracepoint/test_tracepoint.rb: add a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40946 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- internal.h | 1 + 1 file changed, 1 insertion(+) (limited to 'internal.h') diff --git a/internal.h b/internal.h index b49e748f16..89cce7e69a 100644 --- a/internal.h +++ b/internal.h @@ -188,6 +188,7 @@ void rb_w32_init_file(void); /* gc.c */ void Init_heap(void); void *ruby_mimmalloc(size_t size); +void rb_objspace_set_event_hook(const rb_event_flag_t event); /* hash.c */ struct st_table *rb_hash_tbl_raw(VALUE hash); -- cgit v1.2.3
