What happened to worldpilot
by Steve Drees 13 Dec '00

13 Dec '00

I can't seem to find worldpilot on zope.org anymore. Has it been killed? -- Steve Drees SysAdmin/Software Developer/Web Geek/Chief Bottle Washer "A problem well-stated is a problem half-solved." http://www.christianmp3zone.com/savanna

HTML formatting from a text field
by Ausum 13 Dec '00

13 Dec '00

I'm needing a tool that could let a normal user to update a web page, HTML-formatted from a text field within a Zope's form, just like the Compose page at Hotmail, when selecting "Rich Text Format". Does anyone know how to do it? I've tried to find out the technology behind that page, but guess I didn't get too far. Thanks in advance, Ausum

Zope with BBedit: a successful experiment
by Stephane Bortzmeyer 13 Dec '00

13 Dec '00

http://www.zope.org/Members/runyaga/ZopeFAQs/ZopeCompatibleTools says that BBedit have not been tested as a DTML editor for Zope <http://www.zope.org/> but it works fine and is a good solution for MacOS users. A few tricks which may be included on www.zope.org if you think so: BBedit <http://www.barebones.com/products/bbedit.html> has two versions, a free (as in free beer) one and a commercial one. I tried only the first, the second seems to have many useful things for Zope. The official list of plugins at BBedit official site is far from complete (because they allow the free version to be less antiquated by the commercial one?). Most of the plugins are in info-mac/_Text_Processing/_BBEdit. I suggest the HTML plugin (to have some useful HTML menus), the Midex plugin (to translate composed characters since MacOS is not Latin-1) and the FTP plugin (to exchange with Zope). If you transfer with Fetch, for reasons I don't know, the Zserver does strange things in text mode. You have to transfer in binary (which makes you lose the charset translation) and then to import with "LF translation" in BBedit. I prefer to transfer with the FTP plugin (but you still have to convert the composed characters with Midex, which is painful). Unfortunately, it seems no longer maintained. For both FTP clients, don't forget to add the FTP port number (typically 8021) after the host name (separated with a space). I did not test the Interarchy FTP client, which some people recommend. http://www.anybrowser.org/bbedit/ is a good list of tricks for BBedit.

Important Fix for Zope 2.2.x
by Evan Simpson 13 Dec '00

13 Dec '00

Thanks to Jeff Ragsdale, we've finally been able to kill a longstanding bug that allows POST requests to interfere with each other. Symptoms include corrupted or aborted File and Image uploads, and stupid-log messages about "AttributeError: data" killing threads. The attached HTTPServer.py is valid for all Zope 2.2.x versions. I am posting the patched file for earlier Zope versions separately. PLEASE BACK UP <Zope>/ZServer/HTTPServer.py, then replace it with the attached file. Cheers, Evan @ digicool & 4-am

SOAP support in Zope?
by Brad Clements 13 Dec '00

13 Dec '00

I'm thinking of using the MS WebServices IE behaviour with Zope. But when searching the zope site for info on soap, I find only a news announcement saying it will be supported in 2000. I've grepped the source, can't find a mention of soap. I thought someone had posted a patch to enable soap in Zope some time ago, but search doesn't bring it up. Can anyone tell me the status of Soap in Zope? Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com AOL-IM: BKClements

apache/mod_rewrite and user-logging (semi-OT)
by Oliver Bleutgen 13 Dec '00

13 Dec '00

This is not directly a zope-question, but maybe someone has figured out how to solve this. I'm using apache with mod_rewrite to redirect requests for a certain directory from apache to zope (with option [p]). Now for the first time I can't get apache to do want I want it to, that is logging the usernames into apaches logfile. Apache does this only when enabling apache's mod_auth via <Directory Proxy:*> AuthType Basic AuthName "Ihr Login..." AuthUserFile "/httproot/web/bogus_userfile.txt" require valid-user </Directory> or similar, but the silly thing then also wants his own authentication. I am not able to get it to extract the username without really requiring apache authentication. Does anybody know how I could accomplish that? Any dirty tricks to get apache to *think* it authentifies, but letting through every username/password combination, so that zope can do it's job? And no, putting any of this combinations in bogus_userfile.txt is not an option ;->. Another possibility (which gets me more on-topic) is to do that in medusas http_server (which logs a '-' hardcoded), but the only way I could imagine (and code myself) would be to do the base64-decoding there and that seems not quite elegant, even more because apache's log-files hold the client-ip in this situation and therefore are more informative anyway. cheers, oliver

RE: [Zope] HTML formatting from a text field
by sean.upton＠uniontrib.com 13 Dec '00

I remember reading somewhere about messaging between Java applets and JavaScript code in the browser, allowing JavaScript code from a web form to manipulate the applet output; the example was typing something into a text box, clicking a button in a form, and having that rendered in some obscure font inside the applet. Where I read this escapes me, and I've never tried this, but I wonder if such a trick works conversely. In other words, what if the applet can pass values to a JavaScript variable associated with the value of a form input element in the browser's HTML DOM? I could imagine that something like this could be very effective for certain situations where people want better through-the-web editing of code (imagine if you could edit dtml in a web form color coding syntax with a feature to collapse blocks of code, similar to Homesite 4.5, or editing python scripts -- what were python methods -- with an outline-based editor that created automatic indentation). Or, better yet, imagine running JPython within the applet (I don't know whether this is possible) to do all this. Anyway, I wonder if this type of thing could be an alternative to either ActiveX components or a XUL/XPCOM based-interface.

Strange Win2000 Service behaviour
by peter bengtson 13 Dec '00

13 Dec '00

I restarted the Zope server from the Control Panel inside Zope and it took a long time untill it was back up again. About 20 seconds. During these 20 seconds, I started to suspect that the service wasn't working, so I manually pressed the "Start" on the Zope Server inside the Control panel in windows. I couldn't. Below is the traceback I got. I suspect that it means that the Zope server is already running and that I can't start it again (see error and Fs.lock stuff). It turned out that the server was actually running since people on the intranet was using it at the same time as I was struggling with getting the service running. Now the server is running fine, but if I go into the Services in Administrative Tools of the Control Panel, the service ZopeSite is "turned off". So from a quick look on the Win2000 server you can't tell whether the Zope Server actually is running, unless you open a web browser. Strange. It's not a production server and I guess the w2k needs a robust restart with a little kick in the machines direction. Here's the Traceback I got when I tried to start it because I thought it was started: C:\Program Files\Zopesite>start.bat C:\Program Files\Zopesite>"C:\Program Files\Zopesite\bin\python.exe" "C:\Program Files\Zopesite\z2.py" -D Traceback (innermost last): File "C:\Program Files\Zopesite\z2.py", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ?
