Part of my profiling result of a high speed transfer test is attached. What might that <string>:1(connect_ex) be? I only created 2 or 3 TCP connections, but there are 24655 calls. Thanks!

[Twisted-Python] PyPgSQL not locking in adbapi
by Carolina Ardohain June 2, 2005

June 2, 2005

I'm using Twisted 2.0, and pgSQL 2.4. I have two function in plpgsql that access the same table, I have to look if one id is in the table persons, if not then add to the table. I try to lock a table with "LOCK TABLE persons IN ACCESS EXCLUSIVE MODE;", so no both functions try to add the same id. I get 'duplicate key violates unique constraint' when run the two queries at the same time, if I delay one of the functions 1 sec then everything is fine.

[Twisted-Python] twisted.mail.imap4.MessageSet object & imap4 server example
by Sebastjan Trepca June 2, 2005

June 2, 2005

Hi! 1. I don't understand how to use this object. When the fetch method is called, this object is passed containing the requested messages which you then return, right? But is there any easy way to just iterate through it and get the requested UIDis, even if LAST is not set. 2. Where could I find some IMAP4 server examples? Thank you. Regards, Sebastjan

[Twisted-Python] Twisted server connection loss with Mysql
by Raghul J June 2, 2005

June 2, 2005

Hi Friends, My friend gave me a solution for the twisted server to reconnect mysql.This was opening a database connection,excecuting a query and closing the database connection.This works some what fine with my application. I need to confirm that If this is ok and can be deployed in live machine. Some people say that these won't be much suitable and efficient.I also tried by putting cp_reconnect=1 but it didn't work. My code is def excutequery: dbpool = adbapi.Connectionpool("… [View More]

[Twisted-Python] Using twisted.conch.recvline
by Abe Fettig June 2, 2005

June 2, 2005

Hello all, I'm trying to figure out how to hook up the necessary classes in twisted.conch.recvline to add line-editing and history to a simple ssh app. It was easy to modify http://twistedmatrix.com/projects/conch/documentation/examples/sshsimpleser… to use a custom protocol (a simple command-line interface that sends web services requests to a JotSpot wiki), but I can't figure out how recvline is meant to be used. Could someone (Jp?) show me how you'd go about bolting recvline onto sshsimpleserver? Thanks! Abe

[Twisted-Python] Stopping and restarting the reactor
by Brian Granger June 2, 2005

June 2, 2005

Hello, I am using twisted's client capabilities in an interactive setting. To allow for interactive work, I have wrapped all my calls to connectTCP with a class that starts the reactor when a new set of connectTCP calls is made. I stop the reactor in the clientConnectionLost method of my ClientFactory (when there are no more connections). The first time I initiate a connectTCP call in my wrapper class everything works as expected: the reactor is started, twisted does its stuff, and … [View More]

[Twisted-Python] Status update on 2.0 debian packages
by Tommi Virtanen June 2, 2005

June 2, 2005

Hi. Just to let everyone know, twisted 2.0 debs have been uploaded to Debian experimental. As there are a lot of changes from 1.3, they will require manual approval from Debian ftpmasters first. This is 2.0 (+ related lower-versioned projects), not 2.0.1. Hopefully I will have time for the version update sometime later. And just the to be very very clear: 2.0 will never be in sarge. 2.0 will be in unstable _after_ sarge releases.
