Verification shown its source 100% match to currently running version on TMWA.
The following changes were made VS version found in guildsrc.zip:
1) src/build and src/dist content completely removed.
Rationale: build-time artifacts; binaries contained login/password.
2) Executable flag (+x) removed from src/automation.cpp and src/main.cpp.
Rationale: executable CPP sources are weird thing. No change to file content.
3) src/main.cpp changes: 3 lines:
std::string main_username = "test";
std::string main_pw = "test";
std::string main_host = "127.0.0.1";
Rationale: avoid leaking real production credentials and ensure experimenters
dont hammer real TMW prod server by experiments.
Effort been made to preserve original file timestamps, etc. However toplevel src/
dir date adjusted to date of mentioned changes.
