# Adventure Land (MongoDB Edition) - image build
#
# The game is split across three upstream repositories:
#   adventureland_mongodb           -> /app
#   common_engine                   -> /app/common
#   adventureland_secretsandconfig  -> /app/secretsandconfig (template only,
#                                     replaced at runtime by ./config)
#
# All three are cloned at build time, so `docker compose build --pull` is the
# way to update the game.

# Local patch: make the DRM login check switchable (docker/patch-drm-check.js).
# A self-hosted server cannot produce Steam/MAS auth ids, so the check would
# otherwise flag every account with the "authfail" condition. Kept after the
# npm install so the dependency layers stay cached across patch changes.

# Local patch: self-host attribution (docker/patch-attribution.js).
# The license requires a crawlable link back to https://adventure.land, and
# the original project should not appear to support this instance. The phrase
# ships as docker/attribution/{en.js,de.json}; other languages fall back to
# English. Kept after the npm install so dependency layers stay cached.

# Local patch: custom game values and elements (docker/patch-custom-game.js).
# Hooks the loader into main.js and the game server, makes the e.g. Lone Wolf rates
# data-driven, and merges phrase overrides into the language catalogs. The
# loader itself is copied to /app/docker/ in the runtime stage; the custom file
# is mounted at runtime from ./files/custom.

# Local patch: optional email auto-verification (docker/patch-auto-verify-email.js).
# A self-hosted server without SES cannot deliver verification links, so every
# new account would stay "Not Verified". The patch marks accounts verified at
# signup and login when options.auto_verify_email is enabled; without the
# option the upstream behaviour is unchanged.

# Local patch: make the merchant and non-merchant multi-account limits
# configurable (docker/patch-multi-account-limits.js). Upstream hard-codes one
# merchant per IP/owner and three non-merchant characters per IP/owner in the
# backend enforcement cron, while login uses options.ip_limit/character_limit.
# The patch makes both places use options.merchant_ip_limit,
# options.merchant_owner_limit, options.ip_limit and options.character_limit.
