Hi,Andres nagged to me about valgrind runs taking much longer since 9fab40ad introduced the SlabContext into reorderbuffer.c. And by "longer" I mean hours instead of minutes.
After a bit of investigation I stumbled on this line in slab.c: VALGRIND_MAKE_MEM_DEFINED(chunk, SlabChunkGetPointer(chunk));which is wrong, because the second parameter should be size and not another pointer. This essentially marks a lot of memory as defined, which results in the extreme test runtime.
Instead, the line should be: VALGRIND_MAKE_MEM_DEFINED(SlabChunkGetPointer(chunk), sizeof(int32)); Patch attached. -- Tomas Vondra http://www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
