From 4c740bae97f31e16cc6d15753868b6bd49e330d0 Mon Sep 17 00:00:00 2001 From: tenderlove Date: Mon, 12 Nov 2012 21:52:12 +0000 Subject: * probes.d: add DTrace probe declarations. [ruby-core:27448] * array.c (empty_ary_alloc, ary_new): added array create DTrace probe. * compile.c (rb_insns_name): allowing DTrace probes to access instruction sequence name. * Makefile.in: translate probes.d file to appropriate header file. * common.mk: declare dependencies on the DTrace header. * configure.in: add a test for existence of DTrace. * eval.c (setup_exception): add a probe for when an exception is raised. * gc.c: Add DTrace probes for mark begin and end, and sweep begin and end. * hash.c (empty_hash_alloc): Add a probe for hash allocation. * insns.def: Add probes for function entry and return. * internal.h: function declaration for compile.c change. * load.c (rb_f_load): add probes for `load` entry and exit, require entry and exit, and wrapping search_required for load path search. * object.c (rb_obj_alloc): added a probe for general object creation. * parse.y (yycompile0): added a probe around parse and compile phase. * string.c (empty_str_alloc, str_new): DTrace probes for string allocation. * test/dtrace/*: tests for DTrace probes. * vm.c (vm_invoke_proc): add probes for function return on exception raise, hash create, and instruction sequence execution. * vm_core.h: add probe declarations for function entry and exit. * vm_dump.c: add probes header file. * vm_eval.c (vm_call0_cfunc, vm_call0_cfunc_with_frame): add probe on function entry and return. * vm_exec.c: expose instruction number to instruction name function. * vm_insnshelper.c: add function entry and exit probes for cfunc methods. * vm_insnhelper.h: vm usage information is always collected, so uncomment the functions. 12 19:14:50 2012 Akinori MUSHA * configure.in (isinf, isnan): isinf() and isnan() are macros on DragonFly which cannot be found by AC_REPLACE_FUNCS(). This workaround enforces the fact that they exist on DragonFly. 12 15:59:38 2012 Shugo Maeda * vm_core.h (rb_call_info_t::refinements), compile.c (new_callinfo), vm_insnhelper.c (vm_search_method): revert r37616 because it's too slow. [ruby-dev:46477] * test/ruby/test_refinement.rb (test_inline_method_cache): skip the test until the bug is fixed efficiently. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37631 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- test/dtrace/test_object_create_start.rb | 35 +++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 test/dtrace/test_object_create_start.rb (limited to 'test/dtrace/test_object_create_start.rb') diff --git a/test/dtrace/test_object_create_start.rb b/test/dtrace/test_object_create_start.rb new file mode 100644 index 0000000000..756b3b3545 --- /dev/null +++ b/test/dtrace/test_object_create_start.rb @@ -0,0 +1,35 @@ +require 'dtrace/helper' + +module DTrace + class TestObjectCreateStart < TestCase + def test_object_create_start + trap_probe(probe, '10.times { Object.new }') { |_,rbfile,saw| + saw = saw.map(&:split).find_all { |_, file, _| + file == rbfile + } + assert_equal 10, saw.length + } + end + + def test_object_create_start_name + trap_probe(probe, 'Hash.new') { |_,rbfile,saw| + saw = saw.map(&:split).find_all { |klass, file, line| + file == rbfile + } + assert_equal(%w{ Hash }, saw.map(&:first)) + assert_equal([rbfile], saw.map { |line| line[1] }) + assert_equal(['1'], saw.map { |line| line[2] }) + } + end + + private + def probe + <<-eoprobe +ruby$target:::object-create +{ + printf("%s %s %d\\n", copyinstr(arg0), copyinstr(arg1), arg2); +} + eoprobe + end + end +end -- cgit v1.2.3
