The following variables are assumed to be defined by certain functions:

  • GRENADE_DIR
  • TARGET_DEVSTACK_DIR
  • SCREEN_LOGDIR
  • PLUGIN_DIR
  • MYSQL_PASSWORD

save_data

pull the mysql pass from the old config

register a database we should save

Upgrade a service listed in $UPGRADE_PROJECTS.

This function triggers the upgrade process for each project if it exists, otherwise it shows up a warning message about the lack of this file.

NOTE(maurosr): Ideally in a new upgrade test right after a release no new configuration is need, so we can go on without the from-<release> directory. This is also useful due to cross dependencie between d-g and grenade when enabling grenade to run an upgrade between a new pair of releases.

Registration interfaces for external plugins

use caller so that we know the file this function was called from, and we'll derive the location of the plugin directory from that.

If the unit is not found, so fallback to the ps approach

Functions to handle service checking

ensure_services_stopped

wait for services to stop, wait up to 10 seconds because sometimes services take a while to shutdown.

TODO(sdague): work around because worlddump is apparently misconfigured
