Various improvements and additions. I couldn't be bothered to untangle this, so here it goes: * Log colors depending on loglevel * Simplified Filelogger * Remove description=None from basetask * create_list creates task list from argument now * Task rollback feature: If a task fails, the tasklist calls rollback() on the completed tasks in reverse order * Added TaskException to common.exceptions as a base to extend from * Added TriggerRollback task to common.tasks for development purposes * An EBS volume for bootstrapping is now created and attached to the instance (including rollback actions) * EC2 Connect task now depends on host.GetInfo 2013-06-24 23:12:39 +02:00

Remove 'Volume' part from ebs tasks. It's kind of obvious that we are working with volumes in the ebs module. 2013-07-13 13:55:12 +02:00			`class Create(Task):`
Support for partitions MAJOR refactor. The volume is now abstracted into a model along with a partitionmap and partitions. Volumes and partitions are now controlled via an FSM to ensure that commands are called in the proper sequence. GRUB can now be installed properly onto loop devices by using dmsetup to fake a proper harddisk. 2013-09-15 13:19:45 +02:00			`description = 'Creating the EBS volume'`
Put task class properties in identical order 2013-07-09 20:32:50 +02:00			`phase = phases.volume_creation`
PEP8 fixes 2013-06-26 20:14:37 +02:00

Fix #107. Rename before and after task properties `before' becomes `successors' and `after' becomes `predecessors' 2013-11-21 15:54:42 +01:00			`predecessors = [Create]`
