# lib/rally
# Functions to control the configuration and operation of the **Rally**

# Dependencies:
#
# - ``functions`` file
# - ``DEST``, ``DATA_DIR``, ``STACK_USER`` must be defined

# ``stack.sh`` calls the entry points in this order:
#
# - install_rally
# - configure_rally
# - init_rally

# Save trace setting
XTRACE=$(set +o | grep xtrace)
set +o xtrace


# Defaults
# --------

# Set up default directories
DIR=$(dirname ${BASH_SOURCE[0]})
RALLY_DIR=$(readlink -m $DIR/../..)
RALLY_CONF_DIR=${RALLY_CONF_DIR:-/etc/rally}
RALLY_CONF_FILE=rally.conf

# Debug mode
RALLY_DEBUG=${RALLY_DEBUG:-False}

# Create deployment
RALLY_ADD_DEPLOYMENT=${RALLY_ADD_DEPLOYMENT:-"True"}

# Integration with OSprofiler
OSPROFILER_HMAC_KEYS=${OSPROFILER_HMAC_KEYS:-""}
OSPROFILER_CONNECTION_STRING=${OSPROFILER_CONNECTION_STRING:-""}

# Functions
# ---------

# Creates a configuration file for the current deployment
# Uses the following variables:
#
# - ``ADMIN_PASSWORD``, ``REGION_NAME``
#   ``KEYSTONE_SERVICE_URI``
#   ``OSPROFILER_HMAC_KEYS`` - optional, for integration with osprofiler
#   ``OSPROFILER_CONNECTION_STRING`` - optional, if this is set together with
#       OSPROFILER_HMAC_KEYS rally html report will use osprofiler api to
#       generate html report for each trace and embed it as iframe to our
#       native html report
#   ``RALLY_OSPROFILER_CHART`` - optional, a path to store osprofiler's reports
