twisted

I have a twisted server application that maintains persistent connections with around 1000 clients. Each client will occasionally send data to my twisted server, and I would like that server to store data into a MongoDB database. So far, so good. But, the pymongo documentation states something like "there is no good way to use pymongo with twisted". I don't understand why not. Can someone please explain what exactly the problem is and what the pitfalls are? I think it has something to do with pymongo being synchronous, but all I want to do is shove some stuff into the database. If I have a

I inherited a project using the Twisted Python library. The application is terminating after the user logs off of Windows XP. The Python code has been converted to an executable using bbfreeze. In addition, the bbfreeze generated executable is registered as a Windows service using the instsrv.exe and srvany.exe. I've taken a simple chat example from the Twisted website and create an executable from bbfreeze and registered it with instsrv and srvany and the same problem occurs: the executable stops running after the user logs off. I'm inclined to think that something about Windows XP and the

I'm running a django app using twisted. I moved now from http to https. How can I add redirects from http to https in twisted? Jean-Paul Calderone An easy way to generate redirects in Twisted Web is is with the Redirect resource. Instantiate it with a URL and put it into your resource hierarchy. If it is rendered, it will return a redirect response to that URL: from twisted.web.util import Redirect from twisted.web.resource import Resource from twisted.web.server import Site from twisted.internet import reactor root = Resource() root.putChild("foo", Redirect("https://stackoverflow.com/"))

I came across a situation where my scrapy code is working fine when used from command line but when I'm using the same spider after deploying (scrapy-deploy) and scheduling with scrapyd api it throws error in "scrapy.extensions.feedexport.FeedExporter" class. one is while initializing "open_spider" signal second is while initializing "item_scraped" signal and last while "close_spider" signal 1."open_spider" signal error 2016-05-14 12:09:38 [scrapy] INFO: Spider opened 2016-05-14 12:09:38 [scrapy] ERROR: Error caught on signal handler: <bound method ?.open_spider of <scrapy.extensions

On my production server I have periodically happening unicode error but not on my desktop. It appears in logs: 2011-03-17 13:14:53+0000 [GameProtocol,941,95.78.43.17] <unicode instance at 0x9e304a0 with str error: Traceback (most recent call last): File "/usr/local/lib/python2.6/dist-packages/twisted/python/reflect.py", line 546, in _safeFormat return formatter(o) UnicodeEncodeError: 'ascii' codec can't encode characters in position 21-26: ordinal not in range(128) > It doesn't affect any logic in application but it's annoying in logs. The server runs under Ubuntu 10.10 Server, Python 2.6.5,

I have a twisted server that generates log files and rotates them based on size. If the file size of a particular file is more than 1MB, a new log file is created. However, after several days of running, the log files start filling up my hard disk. Is there a way to have an overall limit on log rotation? The limit could be based on total size (like only 200GB worth of logs - anything more would be deleted), or on the number of files (like only 1000 logs would be stored). You can use the option logger. You will have to write your own logger factory, something like this #in module mymodule, file
