commit a31d54acc5d55e7bda567c37799afc8d6e2644af Author: Arturo Filastò <art(a)fuffa.org> Date: Wed Jan 16 18:09:39 2013 +0100 Get Director, TaskManager's, NetTest and oonicli to talk Tests are scheduled through the MeasurementManager, Reports via the ReporterManager and the Director keeps track of everything that is going on. Configurable retries and timeouts are possible. As an example, example_simple.py is run and the reports are written. --- bin/ooniprobe | 14 ++------ nettests/examples/example_simple.py | 8 +++++ ooni/director.py | 7 +--- ooni/managers.py | 5 ++- ooni/nettest.py | 58 +++++++++++++++++++++++++++-------- ooni/reporter.py | 20 +++++++----- ooni/tasks.py | 18 +++++----- tests/test_director.py | 1 - tests/test_managers.py | 2 - 9 files changed, 83 insertions(+), 50 deletions(-) diff --git a/bin/ooniprobe b/bin/ooniprobe index 36f0152..695b137 100755 --- a/bin/ooniprobe +++ b/bin/ooniprobe @@ -1,12 +1,4 @@ #!/usr/bin/env python -# -*- encoding: utf-8 -*- -# oonicli -# ----------- -# Runs ooniprobe tests from command line -# -# :authors: Arturo Filastò, Isis Lovecruft -# :licence: see included LICENSE file - import os, sys import copy_reg from twisted.internet import reactor @@ -19,5 +11,7 @@ sys.path.insert(0, os.path.abspath(os.getcwd())) from ooni.utils.hacks import patched_reduce_ex copy_reg._reduce_ex = patched_reduce_ex -from ooni.oonicli import run -run() +# from ooni.oonicli import run +# run() +from ooni.oonicli import runWithDirector +runWithDirector() diff --git a/nettests/examples/example_simple.py b/nettests/examples/example_simple.py new file mode 100644 index 0000000..24de5a6 --- /dev/null +++ b/nettests/examples/example_simple.py @@ -0,0 +1,8 @@ +from twisted.internet import defer +from ooni import nettest + +class MyIP(nettest.NetTestCase): + def test_simple(self): + self.report['foobar'] = 'antani' + return defer.succeed(42) + diff --git a/ooni/director.py b/ooni/director.py index ac53f5c..6fe3859 100644 --- a/ooni/director.py +++ b/ooni/director.py @@ -118,24 +118,21 @@ class Director(object): def measurementSucceeded(self, measurement): self.totalMeasurementRuntime += measurement.runtime - self.successfulMeasurements += 1 - - return measurement.report.write(measurement) + return measurement.testInstance.report def measurementFailed(self, failure, measurement): self.totalMeasurementRuntime += measurement.runtime self.failedMeasurements += 1 self.failures.append((failure, measurement)) + return failure def reportEntryFailed(self, failure): # XXX add failure handling logic return def netTestDone(self, result, net_test): - print result - print "Completed %s" % net_test self.activeNetTests.remove(net_test) def startNetTest(self, net_test_loader, options): diff --git a/ooni/managers.py b/ooni/managers.py index 818ae5c..533e6b5 100644 --- a/ooni/managers.py +++ b/ooni/managers.py @@ -23,10 +23,13 @@ class TaskManager(object): self.failures = [] def _failed(self, failure, task): + # XXX INFINITE RECURSION LOOP INSIDE OF THIS THING """ The has failed to complete, we append it to the end of the task chain to be re-run once all the currently scheduled tasks have run.
