class ISlaveCommand(Interface):
"""This interface is implemented by all of the buildslave's Command
subclasses. It specifies how the buildslave can start, interrupt, and
query the various Commands running on behalf of the buildmaster."""
def __init__(builder, stepId, args):
"""Create the Command. 'builder' is a reference to the parent
buildbot.bot.SlaveBuilder instance, which will be used to send status
updates (by calling builder.sendStatus). 'stepId' is a random string
which helps correlate slave logs with the master. 'args' is a dict of
arguments that comes from the master-side BuildStep, with contents
that are specific to the individual Command subclass.
This method is not intended to be subclassed."""
def setup(args):
"""This method is provided for subclasses to override, to extract
parameters from the 'args' dictionary. The default implemention does
nothing. It will be called from __init__"""
def start():
"""Begin the command, and return a Deferred.
While the command runs, it should send status updates to the
master-side BuildStep by calling self.sendStatus(status). The
'status' argument is typically a dict with keys like 'stdout',
'stderr', and 'rc'.
When the step completes, it should fire the Deferred (the results are
not used). If an exception occurs during execution, it may also
errback the deferred, however any reasonable errors should be trapped
and indicated with a non-zero 'rc' status rather than raising an
exception. Exceptions should indicate problems within the buildbot
itself, not problems in the project being tested.
"""
def interrupt():
"""This is called to tell the Command that the build is being stopped
and therefore the command should be terminated as quickly as
possible. The command may continue to send status updates, up to and
including an 'rc' end-of-command update (which should indicate an
error condition). The Command's deferred should still be fired when
the command has finally completed.
If the build is being stopped because the slave it shutting down or
because the connection to the buildmaster has been lost, the status
updates will simply be discarded. The Command does not need to be
aware of this.
Child shell processes should be killed. Simple ShellCommand classes
can just insert a header line indicating that the process will be
killed, then os.kill() the child."""
