Zope under Linux -- duh?
by Alexander Staubo 14 May '99

14 May '99

Have you guys ran Zope 1.11 under Linux 2.0.x with Python 1.5.2? I can't get the thing to work. Problem 1: If I try running the version of Python that comes with the Zope sources, I get "bash: ./python: No such file or directory". None of our resident Linux experts could explain this, as the file was seemingly not corrupted. Naturally the install script does not work because of this, and neither does Zope. Problem 2: Python 1.5.2 doesn't compile out of the box with glibc5, as the time module is incompatible with that version. You gotta get a patched version from the CVS repository. Problem 3: Python 1.5.2 doesn't come with a compatible thread module, or so it seems -- at least Python's "make test" reports an incompatibility, and Zope can't import it. I might have to upgrade to glibc6 to get Python to work, I guess. So, what's the deal here? Surely a _lot_ of people are running Zope on Linux.

Well, my understanding is that the main feature of Zope 2 will be ZODB 3. http://www.zope.org/Documentation/Models/ZODB This new object database architecture will allow concurrency in Zope request handling. Basically this means Zope will be multi-threaded. Also you will have more options for storing your Zope data, such as storing it in a RDMS. The upshot of these changes will be improved performance and improved scalability. You may even see exotic things like multiple Zope processes sharing one object database for load balancing or failover. But I'm not making any promises along these lines ;-) So in sum, Zope 2 means a more robust back end, not more user-visible bells and whistles. Of course, you should remember that the impending Zope 2 release will be an alpha source release. So don't switch immediately if you value stability. -Amos

There is probably something wrong happening before the publisher can start the Zope process. We are working on the details for a publisher error protocol so that publishers can participate in presenting useable errors to the user. Till then, cd to the lib/python directory in Zope, run python, and >>> import Main If that works, try: >>> import ZPublisher >>> ZPublsher.Main('') This asks for the index page of your site. You shouldn't get to this point (otherwise it would work for you in the first place) you'll get a traceback at some point, if the error is not obvious, post the traceback. -Michel > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

FYI: Zope mentioned again on scripting news
by Amos Latteier 13 May '99

In regards to Zope, Dave Winer (head Frontier honcho) today says, "...This becomes more interesting as we move towards Unix. We want to deploy apps that scale up to millions of users. We will use Frontier as a content management and rapid development environment. Until we have Frontier running on Linux, we will deploy in some other environment. If we can build a bridge to Zope, and if its applications scale well on Intel hardware, we'll go with Zope...Bottom-line: This is why it's good that Zope is getting XML-RPC." http://www.scripting.com I guess Dave will also be glad to here about the Zope 2 alpha next week since it should improve Zope's scalability story a fair amount ;-) -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

Re: [Zope] - ZAP for Win32?
by reedstrm＠wallace.ece.rice.edu 13 May '99

Zopists - For those who saw my plea on the list, Rob Page sent me his config files, and the thing that seems to have solved it (Accessing Zope under Apache-SSL/Win32) was to remove the drive letter from the rewrite rule substitution. I just successfully authenticated, and am setting up my site as we speak. Yeah! Thanks Rob, and all you other guys at DC, as well. Ross P.S. So, now I've got a secure channel for my shared web space - I'll keep the list informed of any problems I run into. -- Ross J.

ANNOUNCE: COMObject 1.0.1
by Amos Latteier 13 May '99

13 May '99

Hello: I'm happy to announce a new unsupported Zope Product, COMObject. I quickly hacked together this Product to demonstrate how COM can be used with Zope. http://www.zope.org/Download/Prereleases/COMObject Here's an example from the README.txt which gives the flavor of what you can do with this Product: Suppose you have a COM Object named 'word' whose COM Object Dispatch Name is 'Word.Application' You can use this COM Object like so:  <br>  COMObject requires: * Zope 1.11.0pr1 or later (running on win32) * Python Windows extensions * Some understanding of using COM from Python See the README.txt for more information. If you haven't used COM from Python before, then this Product is not for you. This Product is *not supported*. It is simply a proof of concept showing one way to use COM and Zope together. I'm happy to accept patches, and answer questions as time permits, but maintaining this Product is definitely a very low priority. If someone who knows COM well would like to take over this Product (or even just take it as an example, and rewrite the darned thing) I'd be quite happy to cede ownership of it, hint hint ;-) Right now the Product is fairly limited, it's just basically sugar for win32com.client.Dispatch(). I have ideas about how to evolve it, for example, COM Method objects could be added to make access to an object's methods easier and perhaps to wrap results like SQL Methods do. This could also provide finer grained security... Let me know if you find it useful. And don't forget to have fun! -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

ZServer Problems
by Ryan Daum 13 May '99

13 May '99

Using Zope 1.11.0pr1 on FreeBSD 2.2.8 with Python 1.5.2, ZServer starts correctly, fields HTTP, FTP, and PCGI requests, but both HTTP and PCGI don't seem to be publishing modules correctly. They both return this: <module 'Main' from '/usr/local/apache/zope/lib/python/Main.pyc'> .. when accessing the root document .. all other documents (i.e. /manage) return an error (does not exist) Anybody know what's going on?

Q: How to manage a long-running external program
by Evan Simpson 13 May '99

13 May '99

I have an External Method (which fetches, grinds up, and mixes data from several URLs) which can take 30 secs or more to run. Since Zope isn't concurrent yet, it blocks all other requests for an unacceptably long period. I vaguely remember reading about a way to return a "Processing request" page immediately, then have the client automatically retry at intervals until the final response is ready. The Method could easily be made into an external program, but then I'm not really sure of the best way to launch and wait for completion of an external program from Zope. I realize that this is really a general web server question more than a Zope question, but it might be nice to have a Product which can handle this situation automatically. Thanks, Evan Simpson

Database error - cannot lock
by Tom Jenkins 13 May '99

13 May '99

Hello All, I've been out for 2 weeks so I'm just now getting to followup on a message by Alan Johnston. To recap... I installed zope on the new webserver and verified it was working fine. Then we let it sit while we got ready to move the old IIS/frontpage web site over to a zope (and zap) based one. Now when we got ready to move it, surprise!, zope wouldn't run. We'd get the following error in the pcgi.log : "DatabaseError: Could not lock the database file. There must be another process that has opened the file." Alan posted a question on this for me and Bob OConnor answered that it sounded to him to be a file attributes problem. We start zope through an /etc/rc.d/init.d startup script (which calls the zope start script. So I believe we're starting zope (and zap) as root so the user should be nobody, correct? What about the group? What are the correct file permissions for the var directory and the files in the var directory? Thanks for any suggestions you can think of... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tom Jenkins DevIS (http://www.devis.com) python is executable pseudo-code; perl is executable line-noise
