From 241c1a5459d986187ec42f166535d51b37202532 Mon Sep 17 00:00:00 2001 From: tmm1 Date: Thu, 5 Dec 2013 07:45:13 +0000 Subject: gc.c: expose GC.stat() to C-api via rb_gc_stat() * include/ruby/intern.h: add rb_gc_stat() for access to GC.stat variables from c-api * gc.c (rb_gc_stat): new c-api method. accepts either VALUE hash like GC.stat, or VALUE symbol key and returns size_t directly. the second form is useful to avoid allocations, i.e. for usage inside INTERNAL_EVENT_GC tracepoints. * gc.c (gc_stat): add GC.stat(:key) to return single value instead of hash * gc.c (gc_stat_internal): helper method to retrieve single or all stat values * test/ruby/test_gc.rb (class TestGc): test for new behavior * NEWS: note about this new api git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44005 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- include/ruby/intern.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include') diff --git a/include/ruby/intern.h b/include/ruby/intern.h index c1114ae875..cc13557c4e 100644 --- a/include/ruby/intern.h +++ b/include/ruby/intern.h @@ -486,6 +486,7 @@ DEPRECATED(void rb_gc_set_params(void)); VALUE rb_define_finalizer(VALUE, VALUE); VALUE rb_undefine_finalizer(VALUE); size_t rb_gc_count(void); +size_t rb_gc_stat(VALUE); /* hash.c */ void st_foreach_safe(struct st_table *, int (*)(ANYARGS), st_data_t); VALUE rb_check_hash_type(VALUE); -- cgit v1.2.3
