parentAdd a spamchecker callback to allow or deny room joins (#10910) (diff)
downloadsynapse-f4b1a9a527273ef71b2f7d970642b7af45462e0f.tar.xz
Require direct references to configuration variables. (#10985)
This removes the magic allowing accessing configurable
variables directly from the config object. It is now required
that a specific configuration class is used (e.g. `config.foo`
must be replaced with `config.server.foo`).
