# panel-native Windrose runtime image.
#
# Windrose's dedicated server is a Windows-only UE5 build, so we bring along
# just enough Wine + Xvfb to host it headlessly. SteamCMD is NOT installed
# here — the panel's generic updater sidecar uses the official steamcmd
# image and writes into our /game volume.
#
# Expected runtime layout inside the container:
# /game — SteamCMD-installed Windows build (panel volume)
# /game/WindroseServer.exe — dedicated server binary (preferred path)
# /game/R5/Binaries/Win64/WindroseServer.exe — fallback path (UE5 convention)
# /game-saves — ServerDescription.json, R5/Saved save tree
# /entrypoint.sh — boot Xvfb, launch exe under Wine

# Wine: install winehq-stable from dl.winehq.org rather than Debian's
# wine 8.0~repack. Reason: Windrose's UE5 game uses gRPC for its R5 coop
# session. gRPC's Windows event engine asserts on partial-transfer IOCP
# completions ("ASSERTION FAILED: result.bytes_transferred ==
# buffer_->Length() at windows_endpoint.cc:355"). Wine 8.0's IOCP can
# return partial completions for WSARecv that the assertion rejects, so
# the server *crashes* the moment a player session reaches the gRPC
# transport layer (~12 seconds after a join). Wine 9+ on winehq's stable
# repo has the IOCP fix; matches what CubeCoders' AMP wine-stable image
# ships. cabextract + winbind are commonly needed by Wine's installer
# helpers even though we don't call winetricks directly.

# Pre-warm the Wine prefix at /home/panel/.wine during the image build.
#
# Why: Wine 11's first-boot wineboot pops `appwiz.cpl install_mono` to
# install Wine Mono. In a headless xvfb container that step blocks
# indefinitely, and any interrupt (SIGINT, container restart) leaves the
# prefix half-built — kernel32.dll never finishes registering, so the
# next launch dies with "could not load kernel32.dll, status c0000135"
# in a tight crash-loop. UE5 dedicated servers don't need .NET, so we
# skip Mono entirely via WINEDLLOVERRIDES=mscoree= and the Gecko HTML
# engine via mshtml=. Result: first boot is fast and idempotent;
# entrypoint can skip wineboot since system.reg is already present.

# wineboot --init under xvfb-run hangs on Wine 11 because xvfb-run kills

# Run Xvfb directly, give it a moment, point DISPLAY at it, init the
# prefix, then `wineserver -w` to flush state and explicitly stop Xvfb.
