[Twisted-Python] (Un)Twisted Clients and Servers (newbie)
by Bill la Forge May 27, 2004

May 27, 2004

Finally wrote my first Twisted-based client and server: http://compstrm.sourceforge.net/twcs/csprotocol.html Both the client and server are implemented as light- weight processes, where pipes are used for reading and writing to remote processes. This allows the logic flow to be more straight-line. I'm also "translucently" switching threads in the client, using in-line method calls, so that reads and writes to the client do not block the main thread. (I'm trying to show how much clearer … [View More]

[Twisted-Python] Lore question/ latex output question
by Schneider, Michael May 26, 2004

May 26, 2004

Hello All, I have been using lore for a project that I have been working on, and it is a great tool. I have a quick question. Does anyone know how to get the <pre>...</pre> tags to appear as shaded on the latex/pdf output? The generated latex looks like \\begin{verbatim} is being output at the start of the pre and \\end{verbatim} is being output at the end of the pre. I am trying to get the same output format as html output. Thank you very much, Mike -------------------… [View More]

[Twisted-Python] How to organize a web application?
by Alexander May May 26, 2004

May 26, 2004

I am looking for advice on how to organize a web application. I've never written a web application before, and would appreciate any insight into best practices and overall structure. I have html pages, html templates, an underlying database, and (hopefully) an understanding of twisted and nevow. What is the best way to glue all of this together? For example, what is the best way to associate derived rend.Page classes with html templates? I'll have all these different data and render … [View More]

by Anuj Seth May 25, 2004

May 25, 2004

Thanks for any pointers, Anuj. ------------------------------------------------------------------------------------- The information contained in this message is proprietary of Amdocs, protected from … [View More]

[Twisted-Python] Nevow and twisted.enterprise and deferreds
by Alexander May May 25, 2004

May 25, 2004

I am using nevow and twisted enterprise and have a situation like this: dbPool = adbapi.ConnectionPool('myDB') ... class MyPage(rend.Page): ... def data_mydata(self, context, data): return dbPool.runQuery("select * from table") def render_myrender(self, context, data): ... Happily, and a bit unexpectedly, it worked and the page rendered correctly. My issue is if the sql statement fails for some reason the page rendering just hangs. Is there an endorsed way to … [View More]

[Twisted-Python] example stdin handling client that supports readline?
by Ellers May 25, 2004

May 25, 2004

Dear All, I'd like to write a command-line shell-like interface to an in-house database service we have. The DB service provides a socket-based API with messages like 0001-SQL-select * from customer| (where | is a 0x00 char) The server responds with messages likt 0001-SQL-name|age|otherfields||Fred|23|etc I've got the basics going OK. And in a separate script I've got a basic shell-like program going, complete with readline support. It looks a bit like: mysh$ select * from customer [… [View More]
