2020-03-15Avoid doubly showing debug countersTakashi Kokubun
when RubyVM.show_debug_counters is explicitly called. According to the original description in 70fd099220446e39bb80eb0bb32870ce12134619, I think it's not intended to use the exit counter at all, and I'd like to skip it when I need to explicitly call this.

These functions are enabled only on USE_DEBUG_COUNTER=1.

2019-08-07Add a way to print debug counters without exitingAaron Patterson
I am trying to study debug counters inside a Rails application. Accessing debug counters by killing the process is hard because child processes don't get the same TRAP as the parent, and Rails seems to intercept calls to `exit`. Adding this method lets me print the debug counters when I want (at the end of requests for example)

2017-02-21add performance counting mechanism for MRI debug/tuning purpose.ko1
* How to enable this feature? * define USE_DEBUG_COUNTER as 1. * you can disable to output the result with RUBY_DEBUG_COUNTER_DISABLE environment variable even if USE_DEBUG_COUNTER == 1. * How to add new counter? * add COUNTER(<name>) line on debug_counter.h. * include "debug_counter.h" * insert RB_DEBUG_COUNTER_INC(<name>) line on your favorite place. * counter output example: [RUBY_DEBUG_COUNTER] mc_inline_hit 999 [RUBY_DEBUG_COUNTER] mc_inline_miss 3 [RUBY_DEBUG_COUNTER] mc_global_hit 23 [RUBY_DEBUG_COUNTER] mc_global_miss 273 [RUBY_DEBUG_COUNTER] mc_global_state_miss 3 [RUBY_DEBUG_COUNTER] mc_class_serial_miss 0 [RUBY_DEBUG_COUNTER] mc_cme_complement 0 [RUBY_DEBUG_COUNTER] mc_cme_complement_hit 0 [RUBY_DEBUG_COUNTER] mc_search_super 1384 [RUBY_DEBUG_COUNTER] ivar_get_hit 0 [RUBY_DEBUG_COUNTER] ivar_get_miss 0 [RUBY_DEBUG_COUNTER] ivar_set_hit 0 [RUBY_DEBUG_COUNTER] ivar_set_miss 0 [RUBY_DEBUG_COUNTER] ivar_get 431 [RUBY_DEBUG_COUNTER] ivar_set 465 * mc_... is related to method caching. * ivar_... is related to instance variable accesses. * compare with dtrace/system tap features, there are completely no performacne penalties when it is disabled. * This feature is supported only on __GNUC__ compilers. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57676 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
