Progress notification
|
|
|
|
|
=====================
|
|
|
|
|
|
|
|
|
|
*Pungi* has the ability to emit notification messages about progress and
|
|
|
|
|
general status of the compose. These can be used to e.g. send messages to
|
|
|
|
|
*fedmsg*. This is implemented by actually calling a separate script.
|
|
|
|
|
|
|
|
|
|
The script will be called with one argument describing action that just
|
|
|
|
|
happened. A JSON-encoded object will be passed to standard input to provide
|
|
|
|
|
more information about the event. At the very least, the object will contain a
|
|
|
|
|
``compose_id`` key.
|
|
|
|
|
|
|
|
|
|
Currently these messages are sent:
|
|
|
|
|
|
|
|
|
|
* ``status-change`` -- when composing starts, finishes or fails; a ``status``
|
|
|
|
|
key is provided to indicate details
|
|
|
|
|
* ``phase-start`` -- on start of a phase
|
|
|
|
|
* ``phase-stop`` -- when phase is finished
|
|
|
|
|
* ``createiso-targets`` -- with a list of images to be created
|
|
|
|
|
* ``createiso-imagedone`` -- when any single image is finished
|
|
|
|
|
* ``createiso-imagefail`` -- when any single image fails to create
|
|
|
|
|
|
|
|
|
|
For phase related messages ``phase_name`` key is provided as well.
|
|
|
|
|
|
|
|
|
|
The script is invoked in compose directory and can read other information
|
|
|
|
|
there.
|
|
|
|
|
|
|
|
|
|
A ``pungi-fedmsg-notification`` script is provided and understands this
|
|
|
|
|
interface.
|
|
|
|
|
|
|
|
|
|
Setting it up
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
The script should be provided as a command line argument
|
|
|
|
|
``--notification-script``. ::
