It means that memprof report will show their names instead of meaningless address. That's like memprof report for lua script with C modules looks like now: ``` ALLOCATIONS @test.lua:0: 4 events +640 bytes -0 bytes INTERNAL: 3 events +1164 bytes -0 bytes CFUNC 0x7f939831a119: 1 events +29 bytes -0 bytes REALLOCATIONS INTERNAL: 1 events +128 bytes -256 bytes DEALLOCATIONS INTERNAL: 254 events +0 bytes -61020 bytes Overrides: @test.lua:0 HEAP SUMMARY: INTERNAL holds 1164 bytes: 3 allocs, 0 frees @test.lua:0 holds 384 bytes: 4 allocs, 1 frees CFUNC 0x7f939831a119 holds 29 bytes: 1 allocs, 0 frees ``` Memprof report after applying the patch for the same script: ``` ALLOCATIONS @test.lua:0: 4 events +640 bytes -0 bytes INTERNAL: 3 events +1164 bytes -0 bytes /home/maxim/Programming/memprof-demangling/hello.so:say_hello 0x7f939831a119: 1 events +29 bytes -0 bytes REALLOCATIONS INTERNAL: 1 events +128 bytes -256 bytes DEALLOCATIONS INTERNAL: 254 events +0 bytes -61020 bytes Overrides: @test.lua:0 HEAP SUMMARY: INTERNAL holds 1164 bytes: 3 allocs, 0 frees @test.lua:0 holds 384 bytes: 4 allocs, 1 frees /home/maxim/Programming/memprof-demangling/hello.so:say_hello 0x7f939831a119 holds 29 bytes: 1 allocs, 0 frees ``` Part of tarantool/tarantool#5813 Maxim Kokryashkin (3): memprof: extend memprof symbol table memprof: update memprof parser test: adapt memprof tests to new symbol table format CMakeLists.txt | 2 + src/CMakeLists.txt | 1 + src/lj_hash.c | 136 ++++++++++++++++++ src/lj_hash.h | 28 ++++ src/lj_memprof.c | 27 +++- src/lj_memprof.h | 1 + .../misclib-memprof-lapi.test.lua | 5 +- tools/CMakeLists.txt | 2 + tools/utils/hash.lua | 99 +++++++++++++ tools/utils/symtab.lua | 112 ++++++++++++++- 10 files changed, 405 insertions(+), 8 deletions(-) create mode 100644 src/lj_hash.c create mode 100644 src/lj_hash.h create mode 100644 tools/utils/hash.lua --- Github branch in tarantool/tarantool: https://github.com/tarantool/tarantool/tree/fckxorg/gh-5813-memprof-demangling Github branch in tarantool/luajit: https://github.com/tarantool/luajit/tree/fckxorg/gh-5813-demangling-of-c-symbols 2.32.0
