- Image handling - avoiding chaos
by Brad Marsh 13 Dec '98

Hi, I have been playing around with Zope, doing the usual Plutonia tutorial. An immediate questions pops into mind: Do I have to scatter images around the folders? Or can I organize them into "images" subfolders and refer to them implicitly? I tried putting a folder called "root_images" for images that would be common throughout the site in the root folder, copying the logo image into that folder, and then calling it using a var tag. I couldn't get it to work. What's the syntax for calling an object several folders away? Something equivalent to "../../images/logo.gif". Thanks, and cheers!

- Httpdapy and Zope problems
by Grisha Trubetskoy 13 Dec '98

13 Dec '98

Although theoretically I don't see why Zope couldn't work with Httpdapy some day, it currently doesn't really, and here is why: 1. Because Apache runs multiple processes, BoboPOS databases will end up being opened more than once. Since BoboPOS provides no other locking mechanism than "go away I'm busy" using UNIX file locking, you immediately run in to a "Resource Temporarily Unavailable" exception. 2. On Linux, apparently, there is a pretty serious low level problem with using LinuxThreads and Apache together. Zope has a Scheduler object which uses threads. LinuxThreads requires the use of a SIGUSR1 signal, and so does Apache. So when you create a new thread your whole web server hangs. P.S. Not to mislead the public - bare bones ZPublisher i.e. Bobo still works great, by the way, and is still by far my favorite way of writing WWW apps. Grisha

- Re: Zope Win32 feedback and plea for help
by Brad Marsh 13 Dec '98

Hi, all, Just a quick sharing of experience... I tried installing the Win32 version on Win95, and was able to get it going pretty easily. However, when I tried to access the /manage section, I got an error (see below). Paul Everitt answered my query directly, and provided some guidance. I was just now successful starting Zope and opening the /manage section, and here's what I did: Install the Zope binary, use the integrated server (which needs a catchy name, I think). Download and install Python, win32 extensions (all) from the Python web site. They only offer v.1.5.1... Modify the serve.bat file in your Zope root directory to point to the new Python directory and python.exe file. Mine reads: "C:\Program Files\Python\python.exe" "C:\Program Files\Zope\serve.py" Move the stuff that is currently in the Zope\var directory (I put it in a temp directory so it wouldn't get lost). Make sure the var directory is empty. That's it! Run the modified serve.bat and off you go. Good luck...

I can view information on my local IP at port :8080 but as soon as I attempt to look at the management screens, BAM Nothing. 5. Any guidance out there or similar encounters? Thanks in advance. _____ CURRENT I am picking up events in the event logs as follows: I definitly think it is a configuration issue here are the events(4 critical occur): a.The Open Procedure for service "ISAPISearch" in DLL "QPerf.dll" failed.

- FYI: Infoworld article

[must put down baby...one-handed typing is too hard...] Whew, much better. For you weekend Zopers, here's a bit of news: http://www.infoworld.com/cgi-bin/displayStory.pl?981211.whpython.htm The reporter called me on Thursday to chat. Wasn't clear what kind of article he was writing though. Interestingly about ten minutes after I talked to the reporter (Jeff Walsh) I got a call from Dave Winer who had just talked to him. Anyway, Jeff said the article might be in the print edition on Monday. If the binary distributions appear to be pretty stable, then Amos and I will start talking more about Zope next week. Also, I know there is interest in a roadmap that shows what is going to happen when, especially SQL integration. If I can ever get this silly Q&A done, I'll get one online.

I finally updated my Q&A at: www.zope.org/Information/QA It is authored completely in Structured Text with some DTML scripting to assemble the pieces. For those that care, I've attached an External Method which will upload the contents of a directory into a Folder. It fails if the documents already exist (I couldn't figure out how to test for the existance of an object in a folder, has_key failed :^( ) --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909 -------------------------------------- loadfiles.py -------------------------------------- import os def importfiles(self): """Load files from disk into a Folder If you use an editor to manage a bunch of files on disk and you want to keep them current in a Zope Folder, loading them one by one is a pain. It would be nice to have a facility to easily load files on the same machine as the Zope site into Zope. Since External Methods have access to the filesystem, they are a natural fit. Just make sure you pass in 'self' as an argument, allowing the function to invoke Folder methods to add documents. """ directory = 'c:/temp/OSS/QandA' response = 'Starting External Method...' for filename in os.listdir(directory): # Skip things ending in '~' from Emacs if filename[-1] == '~': continue contents = open(os.path.join(directory,filename)).read() try: # See if the document exists, if so, grab it and update it. document = self[filename] document.manage_edit(contents,filename) response = response + '\nAdded %s.' % filename except KeyError: # Document doesn't exist so add it self.manage_addDocument(filename,'',contents) response = response + '\nUpdated %s.' % filename return response if __name__ == '__main__': importfiles()

- Win32 (Win95) feedback and plea for help
by Brad Marsh 12 Dec '98

12 Dec '98

Hi, The Win95 install worked flawlessly. One point: I assiduously went to the Python web site, downloaded 1.5.1 and the Win32 extensions, installed them, installed Zope, then read the readme file (since it's inside the install .exe file). The readme says that it includes a compiled version of Python. Coulda saved me a bunch of downloading time to say that on the Zope download page... Zope runs with the integrated server just fine; I read all the quickstart docs, then tried the management screen link (http://localhost:8080/manage) Error: The server returned an unrecognized response. Now what? Thanks for any help, Brad Marsh, Computer Specialist Center for Evaluation and Research, LLC http://www.tchp.org/cer/
