[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz Aug. 5, 2021

Aug. 5, 2021

hi there, folks: I'd really like to release 0.7.0 but I would like it to be at least a little bit tested before I do so. Could those of you with CVS trees check everything out and see if it performs as advertised? Deeper bugs than that will have to wait for the next release, but I'd at least like to know if it works for someone other than me. Thanks. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |… [View More]

[Twisted-Python] Re: [Twisted-commits] log stderr and non-zero exit code in CGIs, don't show info to users as it is a security risk (closes issue #241)

If it's a security risk, provide a way for the server administrator to turn it off, but this is a _bad_ default. If you doubt the wisdom of making this default, please consult any number of Perl FAQs of the form: Q. "I wrote a CGI and it works perfectly, … [View More]

[Twisted-Python] callFromThread with return
by Egor Cheshkov Oct. 7, 2003

Oct. 7, 2003

Hello! Suppose I run task in worker thread (e.g. database transaction) and I need to do some IO (PB call) and get the result from it during transaction. Since I run not in reactor's thread it's ok to block and wait for the result. I know that there is callFromThread but it never return any result. Is it possible to implement something like callFromThread that can block, wait for result and return it? Thanks in advance, Egor.

Can anybody provide a working, simple example of a SSL-capable web-server using Twisted ? Any hints or clues regarding installation of openssl or other required library is also interesting. Thanks in advance, Thomas

[Twisted-Python] more on IRC frustration
by Glyph Lefkowitz Oct. 1, 2003

Oct. 1, 2003

Mentioning IRC frustrations in my message to paul reminded me of something. There is one stylistic hint in particular I'd like to point out, because it causes the most misunderstanding, and it seems as though it may be particular to our peculiar IRC subculture. If you're in #twisted and somebody says something like this: <usr> Hi there! I am a user with a proble integrating widgets and frobules, and there seems to be a problem with version 2.5-X of Twisted. <dev> i guess you … [View More]

[Twisted-Python] secsh, please compare with conch
by Tommi Virtanen Sept. 30, 2003

Sept. 30, 2003

Hi. I hate duplicated effort (that has not real reason to be duplicated), and noticed this: http://www.lag.net/~robey/secsh/ secsh is a module for python 2.3 that implements the SSH2 protocol for secure (encrypted and authenticated) connections to remote machines. unlike SSL (aka TLS), SSH2 protocol does not require heirarchical certificates signed by a powerful central authority. you may know SSH2 as the protocol that replaced telnet and rsh for secure access to remote shells, but the … [View More]

[Twisted-Python] using ClientFactory from within a server
by Greg Sept. 30, 2003

Sept. 30, 2003

I am having trouble using ClientFactory to communicate from within a server. Specifically, I can't figure out the proper way to exit from the client process. Included is some example code illustrating the problem I am having. It is the simple echo server example, but when someone sends some text to the server, I am trying to talk to an SMTP server to send an email. This is just an example (there are probably better ways to fire off an email), but you get the idea. The client code never "… [View More]exits" and if I try to use reactor.stop() it causes a traceback. So how do I properly exit from this client code, or (being new to twisted) am I going about this in the entirely wrong way? Thanks. #!/usr/bin/env python from twisted.internet import reactor from twisted.internet.protocol import Protocol, ClientFactory, ServerFactory import sys class Echo(Protocol): """This is just about the simplest possible protocol""" def dataReceived(self, data): "As soon as any data is received, write it back." self.transport.write(data) factory2 = MySMTPClientFactory() host = 'localhost' port = 25 reactor.connectTCP(host, port, factory2) reactor.run() print "Returned from sending email" # ^ Never gets to this point class MySMTP(Protocol): def dataReceived(self, data): sys.stdout.write('Server said: ' + data) if data[:3] == "220": self.transport.write("helo foo.com\n") self.stage = 1 if data[:3] == "250": if self.stage == 1: self.transport.write("MAIL FROM:<greg(a)foo.com>\n") self.stage = 2 elif self.stage == 2: self.transport.write("RCPT TO:<greg(a)foo.com>\n") self.stage = 3 elif self.stage == 3: self.transport.write("DATA\n") self.stage = 4 elif self.stage == 4: self.transport.write("QUIT\n") self.transport.loseConnection() #reactor.stop() # ^ This causes a traceback if data[:3] == "354": # Ready to send actual email self.transport.write("This is a test email\n.\n") class MySMTPClientFactory(ClientFactory): def startedConnection(self, connector): print 'Started to connect.' def buildProtocol(self, addr): print 'Connected.' return MySMTP() def clientConnectionLost(self, connector, reason): print 'Lost connection.

[Twisted-Python] deferred folies
by Federico Di Gregorio Sept. 30, 2003

Sept. 30, 2003

hi *, lately i did some dirty Deferred tricks and i just want to know if there is a better way to do what i did. the situation is as follows: a server exposes through pb a "session" object. the client can call on that object "execute" (any number of times) and then "abort" or "end" to end the session. the session is created by calling "new_session" on the remote perspective (after authentication, etc.) now, for a simple get session/execute/end sequence i don't want to write n+1 callbacks (… [View More]
