Re: [Zope] Starting a hosting business

Hi Jake, Thanks for your reply regarding the setting up hosting facilities. I don't think the overhead of running multiple zopes will be a problem (until I approach > 10 clients). Is this as simple as setting up multple instance homes and having them all point at the one version of zope, or do I need one install of zope for each instance home too? I guess the other thing I need to think about is how a request is directed to each instance of zope. I know I can get an instance to listen to just one ip address, so if each domain had it's own ip address, that would be fine. However, if multiple sites share the same ip address, how would I send the request to the correct instance? (using zserver) I hope these questions make sense. Tim Haines.

Documentation Questions
by Andrew Williams 20 Feb '01

20 Feb '01

I have a couple of questions about the best place to get information on objects, methods and properties. Specifically, I am trying to figure out what kind of methods and properties record objects have. I have tried looking through the source code, the mailing list and zope.org, but unfortunately I can't seem to find any info. Can anyone help "steer" me in the right direction? Thanks, Andrew Williams ___________________________________________________________________________ Visit http://www.visto.com/info, your free web-based communications center. Visto.com.

What about Dreamweaver 4? I also heard XMetal would support WebDav as well...

Re: [Zope] Strange TransactionError in ZODB
by Chris McDonough 20 Feb '01

20 Feb '01

Do you allow image uploads? Do you use the catalog? If so in either of these cases, subtransction changes in 2.3.1 b1 might help solve the problem. It also may be an error in the transaction code in either SQLSession or MySQLDA. I'd try 2.3.1 final when it comes out. If you're in a hurry, you can try the beta 1 of 2.3.1 which is available on Zope.org. ----- Original Message ----- From: "Harald Koschinski" <Harald(a)koschinski.com> To: "Chris McDonough" <chrism(a)digicool.com> Sent: Friday, February 16, 2001 11:28 AM Subject: Re: [Zope] Strange TransactionError in ZODB Chris McDonough wrote: > > You didn't receive a StorageTransactionError, you received a > TransactionError.

ansychat.py internal error
by Leichtman, David J 20 Feb '01

20 Feb '01

Can anyone tell me why this might be happening? Recently, and for no apparent reason, the ZServer's been throwing socket errors from ansychat.py's initiate_send. What could cause this? I don't even know where to start in debugging. It seems to be random, and not tied to any particular access or event. It's kind of agrevating when there's no straightforward way to track down the error. And I don't know how to get any more info. I've run in debug mode with a debug log, and run it through the analyzer script, but to no avail. Doesn't produce any errors. Any help or direction would be greatly appreciated. I'm running Zope 2.2.2 on Solaris. Example errors below: 2001-02-20T16:02:35 ERROR(200) ZServer uncaptured python exception, closing channel <FCGIChannel connected 127.0.0.1:54515 at 7be948> (socket.error:(32, 'Broken pipe') [/opt/zope/ZServer/medusa/asynchat.py|initiate_send|211] [/opt/zope/ZServer/medusa/asyncore.py|send|274]) ------ 2001-02-20T16:04:50 ERROR(200) ZServer uncaptured python exception, closing channel <FCGIChannel connected 127.0.0.1:54630 at 7cf3e8> (socket.error:(32, 'Broken pipe') [/opt/zope/ZServer/medusa/asynchat.py|initiate_send|211] [/opt/zope/ZServer/medusa/asyncore.py|send|274]) ------ 2001-02-20T16:05:44 ERROR(200) ZServer uncaptured python exception, closing channel <FCGIChannel connected 127.0.0.1:54317 at 7b7018> (socket.error:(32, 'Broken pipe') [/opt/zope/ZServer/medusa/asynchat.py|initiate_send|211] [/opt/zope/ZServer/medusa/asyncore.py|send|274])

RE: [Zope] newbie batching question

I could be mistaken, but change your line: <dtml-in expr="objectValues('Images')" size=1 start=query_start> to this: <dtml-in expr="objectValues('Image')" size=1 start=query_start> Right now, you are looking for the values of each 'Images', not each Image.

I read through a tutorial and have been working a bit with the Zope Book and there's where I hit a problem. I'm trying to modify the batching example to create a slideshow. Here's what I've got: <dtml-var standard_html_header> <dtml-in expr="objectValues('Images')" size=1 start=query_start> <p>display for any items found: <dtml-var sequence-item></p> </dtml-in> <dtml-var standard_html_footer> (This is stripped down from the code in Chapter 7.)

Hello, i'm using Zope 2.3, ZMysqlDA2.0.4, MySQL-python0.3.1 and MySQL latest rev. Create a table with a date, put in it 1970-1-1 and try to read it. You will got this error: Error, exceptions.IOError: [Errno 22] Invalid argument I think that the problem is in the Y2K patch in datetime.py. Someone can confirm?
