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 --- test/ruby/test_gc.rb | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'test/ruby') diff --git a/test/ruby/test_gc.rb b/test/ruby/test_gc.rb index 7410516c7a..d43f8b8693 100644 --- a/test/ruby/test_gc.rb +++ b/test/ruby/test_gc.rb @@ -79,6 +79,12 @@ class TestGc < Test::Unit::TestCase assert_equal(count[:FREE], stat[:heap_free_slot]) end + def test_stat_single + stat = GC.stat + assert_equal stat[:count], GC.stat(:count) + assert_raise(ArgumentError){ GC.stat(:invalid) } + end + def test_gc_reason GC.start GC.stat[:heap_free_slot].times{ "a" + "b" } -- cgit v1.2.3
