Specifically, look at the ConnectionPool class: There are two kwargs that you can pass, cp_reconnect and cp_good_sql. I use this version in production as part of a simple database uptime monitor, and it works in a satisfactory manner. You may need to trap ConnectionLost errors in some cases, in order to re-send your original query. Hope this helps, Daniel

[Twisted-Python] Parsing POST data inside render_POST
by snacktime 15 Feb '05

15 Feb '05

I couldn't find an example but I thought someone must have one laying around somewhere. The question is, how do I decode the data from an http POST inside of render_POST ? I'm not even sure what variables hold the data, and if there are builtin methods somewhere to decode it and possibly stick it in a dict? Chris

[Twisted-Python] Twisted 2.0 pre-pre release on Windows
by Kevin Dangoor 14 Feb '05

14 Feb '05

Hi, I ran into two problems installing the Twisted 2.0 core pre-prerelease: 1) the post install script referred to by setup.py does not appear to exist 2) the twisted.python.dist module computed the data_files path with a leading "\". So, for example, setup.py tried to copy "\twisted\plugins.tml" rather than "twisted\plugins.tml" and couldn't find it. Kevin

[Twisted-Python] Lock classes for berkely dbm files
by snacktime 14 Feb '05

14 Feb '05

Anyone have any thoughts on using a lock class (using deferreds) versus the built in transaction/locking support in BerkeleyDB? My thought was this. It sure would be a lot simpler to just use a lock class and the python built in dbm functions than having to use the newer bsddb3 module and worry about BerkeleyDb environments and transactions. The application is transaction oriented, and each transaction would have one write and one read, each in a different lock. Anyone see any problems with using a lock class in this way? Chris

[Twisted-Python] Twisted for Corba/J2EE/COM+/etc. integration?
by Wolfgang Keller 13 Feb '05

Hello, dumb question: would Twisted be suitable for the implementation of a server application that exposes its services through Corba/COM/SOAP/whatever client-server communication technology is currently "en vogue"/will be so in the future? TIA, Best regards Wolfgang Keller

[Twisted-Python] Authentication with Perspective Broker and hashed password file
by Dave Cook 13 Feb '05

13 Feb '05

I'd like to authenticate my PB client against a hashed password file, but I'm getting an error when I use a hash: Failure: twisted.cred.error.UnhandledCredentials: No checker for twisted.spread.interfaces.IJellyable, twisted.cred.credentials.IUsernameHashedPassword, twisted.cred.credentials.ICredentials, twisted.spread.pb.IUsernameMD5Password However, if I use plaintext passwords, it works fine. I'm working with the example in the book: http://twistedmatrix.com/documents/current/howto/pb-cred#auto7 with the credential checker set to import sha myChecker = checkers.FilePasswordDB("my_hashed_passwd_file", hash = lambda u, p, h: sha.new(p).hexdigest()) I've tested this checker and hash, and they work fine for logging in to my nevow site. The example works, though if I use plaintext passwords and don't pass in a hash: myPlaintextChecker = checkers.FilePasswordDB("my_plaintext_passwd_file") Thanks for any hints, Dave Cook

[Twisted-Python] apache authentication
by Gustavo Rahal 11 Feb '05

11 Feb '05

Hi I'm using apache as proxy to a xmlrpc server. How do I set the client xmlrpc to connect to apache using ssl, username and password? A prototype of my idea: from twisted.web.xmlrpc import Proxy from twisted.internet import reactor proxy = Proxy('https://localhost/RPC2') """ apache should redirect to 192.168.2.22:7080... how do I send username and password? """" proxy.callRemote('status_mds').addCallbacks(self.buildMDSObject, self.printError) ........ Thanks Gustavo
