From 33af0429ea875cd11d4ffbeff1c278d4cc10bb0e Mon Sep 17 00:00:00 2001 From: mame Date: Wed, 22 Aug 2018 05:24:50 +0000 Subject: thread.c (rb_reset_coverages): remove coverage counters from all ISeqs When coverage measurement is enabled, the compiler makes each iseq have a reference to the counter array of coverage. Even after coverage measurement is disabled, the reference is kept. And, if coverage measurement is restarted, a coverage hook will increase the counter. This is completely meaningless; it brings just overhead. To remove this meaninglessness, this change removes all the reference when coverage measuement is stopped. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64504 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- iseq.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'iseq.h') diff --git a/iseq.h b/iseq.h index b8c10d8816..44ed3bdedf 100644 --- a/iseq.h +++ b/iseq.h @@ -178,6 +178,8 @@ VALUE rb_iseq_first_lineno(const rb_iseq_t *iseq); VALUE rb_iseq_method_name(const rb_iseq_t *iseq); void rb_iseq_code_location(const rb_iseq_t *iseq, int *first_lineno, int *first_column, int *last_lineno, int *last_column); +void rb_iseq_remove_coverage_all(); + /* proc.c */ const rb_iseq_t *rb_method_iseq(VALUE body); const rb_iseq_t *rb_proc_get_iseq(VALUE proc, int *is_proc); -- cgit v1.2.3
