Changelog v2.0.4

General

  • Block user & team name changes if name changes are disabled (Closes #835)
  • Set accounts to unconfirmed if email is changed while verify_emails is enabled
  • Only allow users to change their email to emails with domains in the whitelist.
  • Add email.check_email_is_whitelisted() to verify that a user’s email is whitelisted.
  • Create a get_config wrapper around the internal _get_config to let us set a default config value (Closes #659)
  • Remove utils.get_app_config() from memoization and also give it a default parameter
  • Move utils.logging.init_logs() into utils.initialization and properly call init_logs() to save logs to the logs folder
  • Block the creation of users/teams from MLC if registration_visibility is private
  • Fix showing incorrect ‘CTF has ended’ error if view_after_ctf is set.
  • Fix creating users from the admin panel while name changes are disabled.

API

  • /api/v1/teams/<team_id> now coerced to an int (i.e. /api/v1/teams/<int:team_id>)

Deployment

  • Re-add the LOG_FOLDER envvar to docker-compose so we don’t try to write to the read-only host
  • Stop gunicorn from logging to LOG_FOLDER in docker without explicit opt-in
  • Add ACCESS_LOG and ERROR_LOG envvars to docker to specify where gunicorn will log to
  • Allow DATABASE_URL to contain custom MySQL ports for docker-entrypoint.sh
  • Drop WORKERS count to 1 to avoid dealing with Flask-SocketIO sticky sessions’
  • Install gevent-websocket and use it by default until we have a better solution
  • NOTE: In future releases, websockets functionality will likely be removed. (#852)
