# DATABASE CONFIGURATION
########################################################################
# Zulip's Django configuration supports 4 different ways to do
# PostgreSQL authentication:
#
# * The development environment uses the `local_database_password`
# secret from `zulip-secrets.conf` to authenticate with a local
# database. The password is automatically generated and managed by
# `generate_secrets.py` during or provision.
#
# The remaining 3 options are for production use:
#
# * Using PostgreSQL's "peer" authentication to authenticate to a
# database on the local system using one's user ID (processes
# running as user `zulip` on the system are automatically
# authenticated as database user `zulip`). This is the default in
# production. We don't use this in the development environment,
# because it requires the developer's user to be called `zulip`.
#
# * Using password authentication with a remote PostgreSQL server using
# the `REMOTE_POSTGRES_HOST` setting and the password from the
# `postgres_password` secret.
#
# * Using passwordless authentication with a remote PostgreSQL server
# using the `REMOTE_POSTGRES_HOST` setting and a client certificate
# under `/home/zulip/.postgresql/`.
#
# We implement these options with a default DATABASES configuration
# supporting peer authentication, with logic to override it as
# appropriate if DEVELOPMENT or REMOTE_POSTGRES_HOST is set.

# The Python logging module uses a hierarchy of logger names for config:
# "foo.bar" has parent "foo" has parent "", the root. But the semantics
# are subtle: it walks this hierarchy once to find the log level to
# decide whether to log the record at all, then a separate time to find
# handlers to emit the record.
#
# For `level`, the most specific ancestor that has a `level` counts.
# For `handlers`, the most specific ancestor that has a `handlers`
# counts (assuming we set `propagate=False`, which we always do.)
# These are independent -- they might come at the same layer, or
# either one could come before the other.
#
# For `filters`, no ancestors count at all -- only the exact logger name
# the record was logged at.
#
# Upstream docs: https://docs.python.org/3/library/logging
#
# Style rules:
# * Always set `propagate=False` if setting `handlers`.
# * Setting `level` equal to the parent is redundant; don't.
# * Setting `handlers` equal to the parent is redundant; don't.
# * Always write in order: level, filters, handlers, propagate.
