DEPRECATION NOTICE

The python script in this directory has been deprecated in favour of https://github.com/AffectedArc07/ParaTracyReplay. It runs much faster and doesn't require you compiling a snowflake version of pylz4.

The notes below are kept for reference sake.

Old script notes

This directory contains the replay.py script. This is used to "replay" custom .utracy files generated by the production server.

BYOND-Tracy profiles can use excessive amounts of RAM, upwards of 48GB in a single process if captured normally at runtime. This is not viable for the production server, so they are written as a custom flatfile inside of data/profiler/. These need to be read into tracy over the "network" (localhost) via Tracy.exe or capture.exe. You will need >48GB of RAM for this process. I am not joking.

The version of replay.py in this folder is compatible with the protocol of Tracy 0.8.2. Newer versions will not work. It requires the lz4 python module with the streams extension. This requires manually downloading, building and installing the python-lz4/python-lz4 repo and building with PYLZ4_EXPERIMENTAL=TRUE as an environment variable.
