[Twisted-Python] question about setSubmodel in web.woven.model
by vicky lupien Oct. 24, 2003

Oct. 24, 2003

I took a look in the class Model in the module model and I found one difference. A part of the code is gone in the function setSubmodel. Original code: def setSubmodel(self, request=None, name=None, value=None): """ Set a submodel on this model. If getSubmodel or lookupSubmodel ever return a Deferred, I ought to set this in a place that lookupSubmodel/getSubmodel know about, so they can use it as a cache. """ if value is None: … [View More]

[Twisted-Python] Deffered question
by soso Oct. 23, 2003

Oct. 23, 2003

Hi all, I need to implement a command based protocol, that is a client sends a command to the server and waits for the response. Since the response computation might be time consuming I have to choose between 2 solutions: - use Twisted deffereds - or write my own implementation, a TCP based threaded server. I'm not worried about scaling since it will not be used by more than 10 clients at a time. And the question is, how are deffereds actually implemented? My guess is that there are some … [View More]

[Twisted-Python] Compile failure in 1.1.0rc1 Windows
by Mark Evans Oct. 23, 2003

Oct. 23, 2003

Windows 2000, MSVC6sp5, the full Microsoft SDK is also installed (free from MS website in case you didn't know), as well as MASM for that matter. Necessary Microsoft INCLUDE and PATH environment variables OK, and as per standard. All TM prerequisites like SSL etc are installed correctly. Then tried a simple setup.py install command. The failure is a missing include file referenced from portmap.c. #include <rpc/rpc.h> #include <rpc/pmap_clnt.h> Some clues. On Windows, there *… [View More]is* a VC6 and MSSDK header called rpc.h. However it does not live in a folder called rpc. And there is *no* header called pmap_clnt.h. The last part of the output is shown below. I'm sorry if this is the wrong list, only trying to help out with the rc1 release.

[Twisted-Python] Weird thread count

Hello all, The following client code creates 3 threads on startup, even if there is no server to connect to. And I have no clue why. I'm running on Win2k and that's what taskmanager says.

Yep, that's why I thought is weird. Anyway, I double-checked. I restarted the computer and checked with Spy++ too. Still 3 threads... Also, if you remove the "reactor.connectTCP..." line it behaves ok, only 1 thread. > On Wed, 22 Oct 2003 23:28:31 +0300 > soso <duke99(a)email.ro> wrote: > > > The following client code creates 3 threads on startup, even if there > > is no server to connect to.

[Twisted-Python] Timeouts
by Matteo Giacomazzi Oct. 22, 2003

Oct. 22, 2003

Hi all, I'm doing some tests with twisted.web.client and it is working pretty fine! I've just a doubt: the function getPage accepts a parameter named `timeout' (well, it takes it as a **kwarg and pass it along up to the factory). BTW, this is the timeout in seconds: if the remote host didn't return a response within that time, the errback is called. Now the question: what happens if the remote IP address doesn't respond at all (host unreachable)? I'… [View More]

[Twisted-Python] HTTP Client - HOW TO?
by Matteo Giacomazzi Oct. 22, 2003

Oct. 22, 2003

Hi all, I'm writing a software that needs to query some remote hosts via HTTP (sometimes using GET method, sometimes using POST method): the problem is I cannot figure out how I should use the HTTPClient class or the QueryProtocol class... any hint somewhere? I'm not able to find anything useful in the API docs. Any help will be greatly appreciated! Many thanks in advance. Regards, Matteo

[Twisted-Python] Form with formprocessor
by vicky lupien Oct. 22, 2003

Oct. 22, 2003

I have a form and I'm using formprocessor for validation. I want to get the original form if there's an error and an other page in case of everything is alright. I tried to call formprocessor with callback=self and errback=self but it cause a strange error. Please someone help me, I'm really tired not to be able to use a form. Vicky
