First patch add performance test for memtx allocator. You can copy perf folder to master branch and compare performance. 2. Second patch convert some *.c files to *.cc files. This is the preparation for the patch with allocator choise 3. Third patch implement api for allocator choise 4. Fourth patch add system allocator based on malloc and free This is a completely redesigned patch, however I would like to provide answers to some questions from the previous patch that may overlap 1. malloc_usable_size / malloc_size has different headers in different OS, so i use TARGET_OS_*** to check this in source file not in CMakeLists 2. I test snapshot using checkpoint_interval=5 option, several snapshots are created during my test mechanik20051988 (4): test: add performance test for memtx allocator. memtx: changed some memtx files from .c to .cc memtx: implement api for memory allocator selection Implement system allocator, based on malloc perf/allocator_perf.test.lua | 34 +++ src/box/CMakeLists.txt | 8 +- src/box/box.cc | 3 + src/box/field_map.h | 8 + src/box/lua/init.c | 2 +- src/box/lua/load_cfg.lua | 2 + src/box/lua/slab.c | 214 +------------ src/box/lua/slab.cc | 320 ++++++++++++++++++++ src/box/lua/slab.h | 1 + src/box/{memtx_engine.c => memtx_engine.cc} | 177 ++++++++--- src/box/memtx_engine.h | 53 ++-- src/box/{memtx_space.c => memtx_space.cc} | 94 +++--- src/box/small_allocator.cc | 74 +++++ src/box/small_allocator.h | 58 ++++ src/box/sysalloc.c | 210 +++++++++++++ src/box/sysalloc.h | 145 +++++++++ src/box/system_allocator.cc | 68 +++++ src/box/system_allocator.h | 54 ++++ test/app-tap/init_script.result | 1 + test/box/admin.result | 4 +- test/box/cfg.result | 8 +- test/box/choose_memtx_allocator.lua | 9 + test/box/choose_memtx_allocator.result | 139 +++++++++ test/box/choose_memtx_allocator.test.lua | 44 +++ 24 files changed, 1410 insertions(+), 320 deletions(-) create mode 100755 perf/allocator_perf.test.lua create mode 100644 src/box/lua/slab.cc rename src/box/{memtx_engine.c => memtx_engine.cc} (89%) rename src/box/{memtx_space.c => memtx_space.cc} (93%) create mode 100644 src/box/small_allocator.cc create mode 100644 src/box/small_allocator.h create mode 100644 src/box/sysalloc.c create mode 100644 src/box/sysalloc.h create mode 100644 src/box/system_allocator.cc create mode 100644 src/box/system_allocator.h create mode 100644 test/box/choose_memtx_allocator.lua create mode 100644 test/box/choose_memtx_allocator.result create mode 100644 test/box/choose_memtx_allocator.test.lua -- 2.20.1
