object-storage: refactor to use swift devices
Refactor code to use the devices configuration file setting for account, container, and object servers, dropping mount_path from the fs.conf file, and constructing new account, container and object server rings. This removes the next to last set of diffs in the swift diff file. See BZ 870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589). The key to the change is the dropping of the pre-built account, container and object rings, instead providing a script that will generate them for the user given the gluster volume name in use. In addition, we override the Swift check_mount() method and replace it with Gluster's which attempts to "auto-mount" if it is not already mounted. The following is an enumeration of the changes contained in this refactoring: * The refactoring to override the Swift check_mount() involved condensing a lot of code, removing redundancies and simplifying methods across a number of modules * Drop checking the mount point in the low level DiskDir, DiskAccount and DiskFile objects now that Swift's normal mount checking is used, and enable it by default in the template configuration file * Add missing get_container_timestamp() method for DiskAccount objects * Fix the plugin RPM spec file to provide the new ring builders, and while we were at it, finally fix the over-writing of the configuration files on install * Bug fixes * The monkey patched version of check_object_creation was not working correctly due to a missing import of HTTPBadRequest and a bad reference to validate_obj_name_component() * Only have the utils module import the plugins constraints module for the side effect of monkey patching if gluster is enabled * Removed the db_file.db file in the tree since it is created on the fly * Updated 2011 copyright notices to 2012 Change-Id: I8f4454576b1423021c9bbf3c36176f8db51e62c0 BUG: 870589 Signed-off-by: Peter Portante <peter.portante@redhat.com> Reviewed-on: http://review.gluster.org/4179 Reviewed-by: Pete Zaitcev <zaitcev@redhat.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Tested-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Mohammed Junaid <junaid@redhat.com>
