docker-compose.dev-cache.yml

# Local-developer override: keep downloaded Defold SDKs between test runs.
#
# Without this, /var/extender/sdk lives in the container's writable layer, so every
# `docker compose down` throws the SDKs away and the next run re-downloads and re-unzips
# one per (builder x Defold version) - by far the largest cost of a local test run.
#
# Enabled by server/scripts/start-test-server.sh unless EXTENDER_DEV_CACHE=0, and never
# in CI. Layered with `-f`, so docker-compose.yml stays exactly what CI sees.
#
# Only the builders mount the cache: the frontend is FRONTEND_ONLY and never downloads an
# SDK (only AsyncBuilder does), and keeping it off the shared volume keeps its @PreDestroy
# cache cleanup away from everyone else's SDKs.

volumes:
  # External, so the `extender-test` and `extender-test-auth` compose projects share one
  # cache instead of each getting a project-prefixed copy. Created by start-test-server.sh.

    # stop grace, so a multi-GB delete gets SIGKILLed part-way through - which is harmless
    # for a throwaway writable layer but corrupts a persistent volume, because getRemoteSdk
    # treats "directory exists" as "already verified".
