Para-byond-tracy

Para-byond-tracy glues together a byond server the tracy profiler allowing you to analyze and visualize proc calls. This differs from the standard byond-tracy by the nature of it writing to flatfiles inside data/profiler/. While these files can be up to 30 gigabytes in size, they allow the RAM usage of DreamDaemon to remain very low at runtime, which is useful for profiling entire rounds (A profile from a full round needs >48GB of RAM just to view, let alone save at runtime).

Note that the files generated cannot be loaded straight into tracy. You must use replay.py to load the .utracy file and stream "it over the network" (localhost) into capture.exe as part of Tracy. You can stream straight into Tracy.exe, but this is not advised due to performance overhead.

The above script requires the lz4 library with the stream addon. The instructions for that are out of scope of this guide.

A massive thanks to mafemergency for even making this possible. The below readme is adapted from the original repo (branch: stream-to-file) https://github.com/mafemergency/byond-tracy/

usage

simply call init from prof.dll to begin collecting profile data and connect using tracy-server Tracy.exe

/proc/prof_init()
    var/lib

    switch(world.system_type)
        if(MS_WINDOWS) lib = "prof.dll"
        if(UNIX) lib = "libprof.so"
        else CRASH("unsupported platform")

    var/init = call_ext(lib, "init")()
    if("0" != init) CRASH("[lib] init error: [init]")

/world/New()
    prof_init()
    . = ..()

building

no build system included, simply invoke your preferred c11 compiler. examples:

(AA recommended: If you have the MSVC++ buildchain, open x86 Native Tools Command Prompt for VS 2022 and then cd to this repo. cl should be on your path inside of that CLI environment)

cl.exe /nologo /std:c11 /O2 /LD /DNDEBUG prof.c ws2_32.lib /Fe:prof.dll

clang.exe -std=c11 -m32 -shared -Ofast3 -DNDEBUG -fuse-ld=lld-link prof.c -lws2_32 -o prof.dll

gcc -std=c11 -m32 -shared -fPIC -Ofast -s -DNDEBUG prof.c -pthread -o libprof.so
