From 244916d43b9924f094d268c99df90fd81df68e68 Mon Sep 17 00:00:00 2001 From: normal Date: Tue, 12 Jan 2016 19:26:07 +0000 Subject: resolve class name earlier and more consistently This further avoids class name resolution issues which came about due to relying on hash table ordering before r53376. Pre-caching the class name when it is never used raises memory use, but the overall gain from moving away from st still gives us a small gain. Reverting r53376 and this patch and testing with "valgrind -v ./ruby -rrdoc -eexit" on x86 (32-bit) shows: before: in use at exit: 1,662,239 bytes in 25,286 blocks total heap usage: 49,514 allocs, 24,228 frees, 6,005,561 bytes allocated after, with this change: in use at exit: 1,646,529 bytes in 24,572 blocks total heap usage: 48,891 allocs, 24,319 frees, 6,003,921 bytes allocated * class.c (Init_class_hierarchy): resolve name for rb_cObject ASAP * object.c (rb_mod_const_set): move name resolution to rb_const_set * variable.c (rb_const_set): do class resolution here [ruby-core:72807] [Bug #11977] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@53518 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- variable.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'variable.c') diff --git a/variable.c b/variable.c index 047dbc7e67..842006ed71 100644 --- a/variable.c +++ b/variable.c @@ -2569,6 +2569,13 @@ rb_const_set(VALUE klass, ID id, VALUE val) args.value = val; const_tbl_update(&args); } + /* + * Resolve and cache class name immediately to resolve ambiguity + * and avoid order-dependency on const_tbl + */ + if (rb_cObject && (RB_TYPE_P(val, T_MODULE) || RB_TYPE_P(val, T_CLASS))) { + rb_class_name(val); + } } static void -- cgit v1.2.3
