You cannot run Twisted's test suite using tsr, so who knows what it does? Any change made by any developer to Twisted might break it completely; as a tsr user, you might be the first to notice this circumstance. Not an ideal situation in the least. If tsr is important, I would suggest finding a way to run Twisted's test suite using it. One way to do this is to implement the actual reactor API using a subclass (or some such). Trial might then run the test suite using that reactor subclass. Hopefully there will be support for reactor plugins somewhat soon, but until then you'll need to patch the reactors dictionary at the top of twisted/application/app.py. Jean-Paul

[Twisted-Python] ThreadedSelectReactor
by Timothy Fitz 03 Oct '06

03 Oct '06

Recently there have been some changes to ThreadedSelectReactor, specifically that it is no longer being considered as a stand alone reactor choice (for example, you will no longer be able to twistd --reactor=threadedselect). This action is desirable since there's no reason for it. As I understand TSR it's broken for that usage anyway; however, I have been warned that TSR is completely broken and shouldn't be used at all. What exactly and specifically are the current problems or at least symptoms of TSR and is it truly broken?

[Twisted-Python] twistd save state does not work
by Remi Cool 02 Oct '06

02 Oct '06

Hello, I've readied my app for use with twistd, the daemonizing works, but a tap file is not saved upon exit (kill 'cat twisted.pid'). How can I enable the save state option? BTW I'm not using the -o option with twistd ;) Second ... is it possible to disable the twisted logging if you use twistd to start the app? Or is it possible to set a log level so that only warnings and errors are shown and my log is not flooded with (TCPServer) connection messages. - Remi -

[Twisted-Python] _pollingfile._PollingTimer
by Manlio Perillo 02 Oct '06

02 Oct '06

Since the _PollingTimer can be reused for a possible console support, why not to make it a public "simil reactor"? As an example: class UPollReactor(object): """User mode polling reactor, for Windows. Note that this is not a real reactor. """ def addResource(self, resource, action): ... def run(): # add a fake resource, just to do the job done by twistd with the # TimeService ... twistd can, as an example, always "run" the UPollReactor when on a windows system.

[Twisted-Python] Removing _wait from Trial
by Jonathan Lange 01 Oct '06

01 Oct '06

So, I would like to remove _wait() from Trial and make it work like a regular Twisted application. I've had all this stuff on my brain, and have decided to dump it here for feedback. Here's how the plan looks at the moment[1]: 1. Deprecate the use of reactor-spinning things within tests. (Twisted 2.5) We've already done a great deal of work on this. spinWhile, spinUntil and util.wait have alll been deprecated and removed. #2090 (ready for review) actually issues deprecation warnings when the reactor is iterated, crashed or stopped within a test. Unfortunately, some of Trial's cleanup code spins the reactor (see t.trial.util._Janitor.do_cleanPending). This has to go. 2. Tighten test cleanup errors. (Twisted 2.5) #2091 (ready for review) fulfils a long-standing promise. The "reactor unclean" warnings have been turned into errors. It doesn't help us remove _wait, but To remove _wait, we'll also have to remove the two calls to reactor.iterate() from _Janitor (see #2092). That means that many tests that *thought* they were cleaning up the reactor properly will find out that they weren't. We can reduce the number of errors by simulating reactor.iterate() using callLater. However, experiments show that even with this bandaid, there will still be new errors in the Twisted suite. That means we will have to either: a) surprise our users with new errors in their tests b) find some way to introduce this gradually. Obviously everyone[2] would prefer b). I've filed #2124 explaining how that might work. 3. Introduce asynchronous APIs to Trial (Twisted 2.6) Currently TestCase.run() is a blocking call. I wish it could remain a blocking call, but it can't. The branch for #1781 makes a SyncTestCase and an AsyncTestCase. run() works in SyncTestCase and doesn't work in AsyncTestCase. For AsyncTestCase, one uses runDeferred(). Although the branch for #1781 will need to be abandoned, these new classes should be brought in for Twisted 2.6 (without breaking run()). Naturally, this affects many, many tests in Trial. We might even add runDeferred to TestSuite at this point. 4. Deprecate TestSuite.run and TestCase.run. (Twisted 2.6) Neither of these will work without wait[3] and they are both public APIs. Also remove the calls to iterate() from _Janitor at this point. 5. Actually remove _wait. (Twisted 2.7) Add runDeferred() to TestSuite, make run() raise NotImplementedErrors for TestCase and TestSuite. Alter TrialSuite to start and stop the reactor. I can't find a theory to explain why this change will break unexpected tests in the Twisted suite. However, it will certainly happen. That means that some tests in user code will probably break as well. I don't know how we could make this any smoother. Questions: - What should I do with the ticket #1781? - What should I do with the branch for #1781? - What more can we do to reduce the number of tests that will break when _wait is removed? - Thoughts? thanks for getting this far :), jml [1] Incidentally, all of this would be superfluous if reactors were restartable. [2] Well, almost everyone [3] ... or restartable reactors.

[Twisted-Python] how can I invoke an httpFactory method in http.request?
by wang wei 01 Oct '06

01 Oct '06

hi, is that a way to invoke a function in httpFactory from a http.request? code here: from twisted.web import http class anotherRequestHandler(http.Request): def process(self): ''' how to invoke a method in anotherHttpFactory such as judge? ''' class anotherHttp(http.HTTPChannel): requestFactory = anotherRequestHandler class resolve: def show(self): return 'ok' class anotherHttpFactory(http.HTTPFactory): def __init__(self): a = resolve() def judge(self): return a.show() I don't want class 'resolve' to be initialized every time when a request comes, or am I mis-understand it ? Thanks for help.
