Forum: Ruby-core Compile-time constant for HEAP_GROWTH_FACTOR (patch attached)

Issue #2837 has been updated by nobu (Nobuyoshi Nakada).


This patch contains not only the subject but also the accessors.
It isn't acceptable and you should separate them, I think.

 The GC currently increases the size at which newly-created heaps by a 
factor of 1.8 for each heap.  Some find it appropriate to modify this 
value (REE uses a value of 1 instead of 1.8, for example).  In the trunk 
version of this code, that value is hard-coded in as a constant at 1.8 
in gc.c:980.

 I've included a patch to expose this as a compile-time constant 
(HEAP_GROW_FACTOR), and also included getters and setters in the style 
of the patch I submitted in Issue 1047:
