Advanced Workflow

Process execution flow

TODO

• task resolution & blocking
• wrapping execution in subprocess
• errors & skips
• orphan tasks

Events

Events are being send around process execution (see CleverAge\ProcessBundle\Event\ProcessEvent) :

• cleverage_process.start : on process start
• cleverage_process.end : on successful process end
• cleverage_process.fail : on failed process end (with the associated error)

Another event is send when a process is executed with the CLI (see CleverAge\ProcessBundle\Event\ConsoleProcessEvent) :

• cleverage_process.cli.init : before executing any process, giving access to console Input/Output objects

You can also use EventDispatcherTask to manually trigger an event in the middle of a process.

Parallelization

TODO

• ProcessLauncherTask
• pthread
