problem using ssl from zope
by Laura Skosnik 27 Apr '05

27 Apr '05

Hello, We are having a similiar problem, did you ever find a solution to this issue? When we test in the python console, the connection is fine. We get this error from python 2.3.5 when making secure socket connections from my mod_python based application. It is very odd because we cannot replicate this in the development environment, only in production on a cluster of 2 debian boxes with Apache2 MPM Worker w/ Mod Python 3.13. Does anybody have any ideas as to what could be causing this error? Here is the full traceback: Traceback: File "/home/orderform/www/cgi-bin/OrderForm_bundle/hwmodules/register/dp_registrar/DPRegistrar.py", line 95, in _ _execCmd con.endheaders() File "/usr/lib/python2.3/httplib.py", line 715, in endheaders self._send_output() File "/usr/lib/python2.3/httplib.py", line 600, in _send_output self.send(msg) File "/usr/lib/python2.3/httplib.py", line 567, in send self.connect() File "/usr/lib/python2.3/httplib.py", line 988, in connect ssl = socket.ssl(sock, self.key_file, self.cert_file) File "/usr/lib/python2.3/socket.py", line 73, in ssl return _realssl(sock, keyfile, certfile) TypeError: ssl() argument 1 must be _socket.socket, not _socketobject The thing is that if we restart the web server, it works fine for about 20 minutes after which we start getting these errors. Any help would be appreciated. Thanks, Laura

Re: How can I make class variables store in the zodb??

I don't understand all the issues, but from an AT-user's point of view, it'd be very nice to have a fully supported dictionary and array field. I'm very interested in using the ATExtentions, but am wary of exposing myself to code that may not be future-proof. Practically speaking, is the risk low for using these ATExtensions?

I certainly don't think having things in two places will be helpful - people won't know where to go for updates, bug fixes or contributing, and things will end up out of sync very, very quickly. I don't quite see the benefit of amalgamating a losely related set of fields and widgets into a single product. Usually, you only want one or two of them, and downloading a couple of products is not all that hard. Having a single "library" makes sense when its contents are closely related, either in approach, functionality, maturity, quality control or importance. Trying to make a "one size fits all" product is imitating the problem Archetypes itself has been amassing for some time. Modularising will make the whole collection much more managable, imho, especially if the quality and maturity of various components will vary within the library. If there is a need for a single "libary", why not use svn bundles and tarballs thereof to collect a number of tried-and-tested products into a single download? Martin -- (muted)

How can I make class variables store in the zodb??
by Peter Millar 26 Apr '05

26 Apr '05

One thing we have noticed in our development of a plone archetype product is that archetype fields get stored in the zodb, whereas class variables do not (which is fine). Plone portal tools have their properties stored in the zodb. How do you get variables to store their data in the zodb?? If I wanted to store an archetype class variable to the zodb how could I do it . besides making it an archetype field?? ____________________________________________ Peter Millar Technical Project Manager Parasyn Controls Pty Ltd Peter.Millar(a)Parasyn.com.au T: 61 7 3396 6388 F: 61 7 3396 6299 45 Millenium Place, Tingalpa QLD 4173 PO Box 400 Cannon Hill QLD 4170 Australia www.parasyn.com.au <http://www.parasyn.com.au/>

What is Flash Communication Server and Help
by Birol BI�AKLI 26 Apr '05

26 Apr '05

Macromedia Flash Communication Server MX is a server based platform for creating and deploying compelling, interactive web-based audio/video applications such as video on demand, live event broadcasts, webcam chat, and real-time collaboration applications. This software includes fine properties but, I started to think there is not any open source software that includes all of these features. So, I decided to get a software that makes only audio/video streaming for now. It must communicate two or more clients by doing live broadcasts. If you know any "open source" software which has minimum this property and can be run in Zope applications, please suggest me.

Memorysegment error in Zope
by Max M 26 Apr '05

26 Apr '05

I am writing an Imap client. The Imap server (Groupwise) I connect to is really slow at accepting logins. So I have made a connection pool where I store the open connections to the server. But once in a while I get a memory segment error on the server and it crashes. I suspect what happens is that a connection has been idle for to long, ad the connection dropped by the imap server. Which might cause some memory to be freed that is then accessed when I call noop(). It could also be be some kind of threading problem. Does any of you hav an ide as to how I can find out? I am not used to these kind of problems, having been spoiled by Python for too long. regards Max M I have attached the connection pool code in the bottom. ########################################## # a borg/singleton for pooling connections. # Necessary as login can take a looong time class ConnectionPool: __shared_state = {} def __init__(self): self.__dict__ = self.__shared_state def getConnection(self, server_uri, user, password): if not hasattr(self, 'connections'): self.connections = {} user_key = (server_uri, user, password) user_connections = self.connections.setdefault(user_key, []) # first try and return a connection from the pool for i in range(len(user_connections)-1, -1, -1): # a connection can be timed out, # try noop to see if it's still open connection = user_connections[i] try: connection.noop() return user_connections.pop(i) except: # else login again user_connections.pop(i) # if no usable connections in the pool, # create new one and return it return Imap4Connector(server_uri, user, password) def release(self, connection): # take the connection and put it in the pool user_key = (connection.server_uri, connection.user, \ connection.password) user_connections = self.connections.setdefault(user_key, []) user_connections.append(connection) -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science
