[Twisted-Python] Setting a timeout for HTTPDownloader
by Edd Dumbill Aug. 12, 2003

Aug. 12, 2003

Hello, Firstly, thanks for Twisted, I'm just starting to use it and I'm impressed with what I see. I'm also grateful for the help folks have given me on the IRC channel. So here's my problem. I'm adapting the spider from Twisted to my own purposes. One problem I've come across is this: that an HTTP connection will be opened OK, but is just held open with no return for many many minutes by a server. So, I want to implement a timeout. As I understand it, this is different from the timeout … [View More]

[Twisted-Python] RFC - List hierarchies in Woven
by Abe Fettig Aug. 11, 2003

Aug. 11, 2003

Attached you'll find a patch for twisted.web.woven.widgets. This patch is designed to let the List view handle hierarchical data, and therefore generate tree structures and menus instead of plain lists. Currently this patch works by checking each Model object within a list for a "children" attribute. If the Model has a "children" attribute, the List view generates a child set of nodes, using its template as the view and the contents of the "children" attribute as the model. Sorry if this … [View More]

[Twisted-Python] Uninteruptable infinite loop: Woven rendering
by Mary Aug. 11, 2003

Aug. 11, 2003

The problem I'm describing is best illustrated by the two examples attached. safe.py renders the following HTML for the / URL (Twisted 1.0.7alpha4): <?xml version="1.0"?> <html> <body> <h1>My name </h1> </body> </html> If I start bad.py like this: "twistd -n -y bad.py" and request the / URL, it infinitely loops (judging from the output of --spew), and further, renders twistd uninteruptable via either Ctrl-C or SIGTERM. In this particular case … [View More]

[Twisted-Python] static.Data and embedded URL's...
by Stuart Hungerford Aug. 11, 2003

Aug. 11, 2003

Hi all, I'm using twisted.web for an application that generates very simple HTML page responses. It's probably way too simple to consider using Woven. I've have some resources inheriting from twisted.web.static.Data and in their render() method they use a very simplistic template/substitute: def render(self, request): lines = load_template('foo.html') lines = lines % ('foo', 'bar') return lines My question is how embedded URL's in the string result … [View More]

[Twisted-Python] Twisted and Postgresql
by Edmund Dengler Aug. 10, 2003

Aug. 10, 2003

Greetings! When trying to transfer a row set, which was obtained using the pyPgSQL module, I am having problems with specific types not being jelly-able. In particular, the row itself PgResultSetConcreteRow(?)(this is from memory) and PgInt2 (which I found out by trying to send individual elements of the row set over). Has anybody else encountered these, and is there a solution other than defining my own set of jelly-able components (for example, is there a stock jelly library someplace)? I … [View More]

[Twisted-Python] Sessions and URLs
by Edmund Dengler Aug. 10, 2003

Aug. 10, 2003

Hi all! Dug into the library. It looks like woven.guard.SessionWrapper is setup to return a child EVEN IF YOU DO NOT HAVE A SESSION!!. Basically. the code structure of getChild() looks like (I could be wrong in my understanding, so please correct if I am making a mistake): some setup stuff if we have a session key as the next bit in the path ... if the key matches the cookie we have cookies enabled, get rid of the embedded key ... else (… [View More]

[Twisted-Python] Deferring the return within PB
by Edmund Dengler Aug. 9, 2003

Aug. 9, 2003

As I forge ahead, another question rears it's ugly head to be thrashed! I am calling a PB perspective method from the client to the server. def perspective_transferXXX(self, XXX): ...deal with this item... I would like to perform a database operation on the server end. How do I defer the return statement til the operation is done? Roughly speaking: def perspective_transferXXX(self, XXX): ...perform the database operation, defer to doneTransferXXX()... ...do … [View More]
