[Twisted-Python] determine the number of incoming tcp connections
by Ricardo Niederberger Cabral 02 Dec '03

02 Dec '03

How can i ask my twisted.internet.app.Application or twisted.spread.pb.Root how many incoming tcp connections it currently has ? I failed to find such thing on the API (or didn't try hard enough :/ ), so should i make the other side say "i'm alive" and then count myself the number of "i'm alive"s i get ? Best regards, -- rnc <nieder at mail dot ru>

I don't believe there's any major changes in UDP in this release. Note that shtoom (shtoom.sf.net) is using UDP quite heavily, and hasn't had a problem.

Are there any significant UDP bug fixes or enhancements that make it worthwhile to migrate immediately to the new 1.1.1 release candidate? How stable is this rc, generally speaking? -Mark

[Twisted-Python] Woven and nested database queries
by Wenderson Teixeira 01 Dec '03

01 Dec '03

Hi, I'm new to the list and I'm just starting with Twisted and Woven. I think the framework is great, but I'm having some problems. When I try to make two nested <div>, both with independent queries, I get na error, the solution I've found is to create another model called "loaddata", which does nothing, except call the queries. If anyone knows a better way, I'd like to hear, I've searched all over the Internet, and found nothing that could help. Thanks in advance, Wenderson Teixeira Here is the minimum working code that exemplifies it: from twisted.web.resource import Resource from twisted.web.woven import page from twisted.web import microdom from twisted.enterprise import adbapi class A(page.Page): # When "loaddata" is not present, I get the following error: # exceptions.AttributeError: DeferredWidget instance has no attribute 'd' template = """ <html> <body> <div model="loaddata"/> <p>A</p> <div model="a"> <div view="Text"/> <p>B</p> <ul model="b" view="List"> <li pattern="listItem" view="Text" /> </ul> </div> </body> </html> """ def wmfactory_loaddata(self, request): self.runAQuery(request) self.runBQuery(request) return [] def wmfactory_a(self, request): return self.runAQuery(request) def wmfactory_b(self, request): return self.runBQuery(request) def runQuery(self, queryStr, attr, callback): if not hasattr(self, attr): dbpool = adbapi.ConnectionPool("pyPgSQL.PgSQL", "192.168.1.180::manesco_01:manesco") deferredQuery = dbpool.runQuery(queryStr) deferredQuery.addCallback(callback) dbpool.close() return deferredQuery return getattr(self, attr) def runAQuery(self, request): # Sample data #return [[1, 'Wenderson', 'WT', 2, 'Tex', None]] return self.runQuery("SELECT * FROM advogado WHERE id_adv=77", "aDataset", self.gotAResult) def runBQuery(self, request): # Sample data #return [ # [1, 'Advogado Sr.'], # [2, 'Advogado Pleno'], # [3, 'Advogado Jr.'], # [4, 'Estagiario'], # [5, 'Assist. Criatividade'], # [6, 'Empresario'], # [7, 'Departamento Pessoal'] #] return self.runQuery("SELECT * FROM categoria", "bDataset", self.gotBResult) def gotAResult(self, data): self.aDataset = data return data def gotBResult(self, data): self.bDataset = data return data resource = A(directory = "C:\inetpub\wwwroot\man")

[Twisted-Python] Re: using twisted web server as a type of REST server
by Oliver Nelson 01 Dec '03

01 Dec '03

Ok, I've got something kinda working now. I think I need to do a bunch more reading now as it looks like I've found a framework for my project :) Now I need to get much better at Python and the twisted library. I guess I'll try dropping in on IRC channel as I have questions. I'm not a big IRC guy, do I just sign in and ask away? OLIVER
