hi, i sometimes got this traceback from zope, and my site will be in a totally unusable state. i use zope2.2.2 with zeo0.4.1 and postgresql6.5 on RH linux. i'm not sure whre the bug lies. also, can anybody be so kind and point me to where i can check postgresql error the traceback ------ 2000-11-16T03:08:04 PANIC(300) ZODB A storage error occurred in the last phase o f a two-phase commit.

Problems with External Method
by Oleg Broytmann 18 Nov '00

18 Nov '00

Hello! I've stucked with a problem with External Methods. I wrote an External Method and sterted to debug it. After some period of bugs fixing in the method Zope responded "Error. Cannot import default_render..." and oops - my Method removed from its folder... Not exactly "removed" - Zope converts it to a folder-like object (there is folder icon on it instead of External Method icon), but I cannot enter the folder. I removed the folder, recrated External Method and continued debugging. But Zope continues to "remove" the method from time to time, and the more I work on the method the more frequently Zope requires me to recreate the Method. What's this? Normal behavior on buggy External Method or bug in the very Zope? My Method is very simple, I do not touch Zope internals there... or at least I *think* I don't touch :) (Zope 2.2) Oleg. ---- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

Big Work Ahead - any advise ???
by George Osvald 18 Nov '00

18 Nov '00

Hello Everyone, I have been playing with ZOPE for some time and I absolutely love it. I have my own site running without a problem for about six months. Recently I was able to demonstrate ZOPE to a "VERY" major player in entertainment industry (music and video). I sold the idea to them and in about one month I am supposed to start to redesign a major web site(and then may be another one). It contains about 2000 pages at the moment. Is there anything I should be aware of when designing a site of such magnitude in ZOPE? (streaming video and music is not going to be served from the ZOPE site) George Osvald

Running Mailman CGI under Zope ZServer
by Fred Wilson Horch 18 Nov '00

18 Nov '00

Hello out there, I'm looking for someone with some more Zope "Zen" to help me figure out how to add support for legacy CGI scripts (specifically Mailman 1.1) to Zope. To recap, I know and understand how to get Apache to play nicely with Zope. What I'm trying to do is remove the need for Apache by allowing ZServer to serve CGI scripts itself. The motivation is to allow me to run Mailman 1.1 on my Zope site without having to have Apache (or any other web server) configured and running. First, am I really the first person to try running CGI scripts from ZServer? I have found some hints here and there of people doing somewhat similar things, but I haven't yet found a product for easily adding legacy CGI scripts to a Zope site. It seems most people run Zope behind Apache. Is ZServer really slow or buggy or something? Second, is Mailman going to be integrated with Zope? It seems like a natural fit. It would be nice to move away from the pipermail archiving and use the Zope object database for archiving messages instead. Third, thanks to code from Eric Walstad and Chris Withers (author of PathHandler), I have hacked up an external method that sort of works. It attempts to add to Zope the functionality of ScriptAlias in Apache. But I'm running into some problems with the HTTP header. The attached code simply ignores the HTTP header sent by the Mailman CGI script, letting Zope do its thing. But this becomes a problem when Mailman wants to set cookies for authentication. Can anyone help me figure out how to convince Zope to let the CGI script send both the HTTP header and message body? Thanks, Fred Here's my external method. It is called by a Path Handler object. Some notes: 1) REQUEST['PATH_INFO'] seems to be brain dead 2) the path_to_handle key is inserted by the PathHandler product 3) this is written for Linux; I'm not sure how Windows handles os.popen 4) I don't understand why sometimes this function gets called with one argument and sometimes with two -- I always just ignore the second argument import os, os.path, string def testing(self, second=None): if self.REQUEST.has_key('path_to_handle'): script = self.REQUEST['path_to_handle'][0] if script: script_path = '/home/mailman/cgi-bin/%s' % script if os.path.isfile(script_path): ENV = '' if len(self.REQUEST['path_to_handle']) > 1: ENV = ENV + 'PATH_INFO=/%s' % string.join(self.REQUEST['path_to_handle'][1:],'/') elif self.REQUEST['PATH_INFO'][-1] == '/': ENV = ENV + 'PATH_INFO=/' ENV = ENV + ' HTTP_HOST=%s' % self.REQUEST['HTTP_HOST'] ENV = ENV + ' SERVER_NAME=%s' % self.REQUEST['SERVER_NAME'] f = os.popen("/usr/bin/env %s %s" % \ (ENV, script_path)) header = 1 while header: if (f.readline() == '\n'): header = 0 output = f.read() # grab the output of the CGI here status = f.close() else: return '%s: CGI script not found.' % script else: return 'No CGI script specified.' else: return 'No path to handle.' return output + '<hr>' + str(self.REQUEST.keys()) + '<hr>' + str(self.REQUEST)

Need some help with installing ZPatterns
by Steve Waterbury 18 Nov '00

18 Nov '00

I'm a newbie. Have successfully installed the precompiled Zope 2.2.2 on Solaris 2.6, running with apache 1.3.14 via fastcgi. Now trying to install ZPatterns-0-4-3b2. Untarred it into the zope dirs, so now its source is in zope/lib/python/Products/ZPatterns Following the instructions in README.txt, I looked for a Makefile.pre.in ... it wasn't included, so I looked around in the zope distribution and found one in /lib/python/Shared/DC/xml/pyexpat -- it claims to be "Universal Unix Makefile for Python extensions", and it says it works with Python 1.5 or newer: # Build *and install* the basic Python 1.5 distribution. See the # Python README for instructions. (This version of Makefile.pre.in # only withs with Python 1.5, alpha 3 or newer.) ^^^^^ (sic -- is that a Python idiom? :^) ... so I figured it might work, but when I try "make -f Makefile.pre.in boot", I get the following: rm -f *.o *~ rm -f *.a tags TAGS config.c Makefile.pre python sedscript rm -f *.so *.sl so_locations VERSION=`python -c "import sys; print sys.version[:3]"`; \ installdir=`python -c "import sys; print sys.prefix"`; \ exec_installdir=`python -c "import sys; print sys.exec_prefix"`; \ make -f ./Makefile.pre.in VPATH=. srcdir=. \ VERSION=$VERSION \ installdir=$installdir \ exec_installdir=$exec_installdir \ Makefile make: Fatal error: Don't know how to make target `/vol01/software/zope/lib/python1.5/config/Makefile' Current working directory /vol01/software/zope/lib/python/Products/ZPatterns *** Error code 1 make: Fatal error: Command failed for target `boot' ****************** What blockheaded thing am I doing?

off toic, but... ange-ftp only works as unix root
by Bill Welch 18 Nov '00

18 Nov '00

even though I can ftp into zope from unix root and non-root. As unix non-root, ange-ftp asks for password and then hangs emacs. Does respond to C-g. Same zope user in all cases. The obvious problem is some file or port permission, but I'm hoping someone can show me the way instead of me going for another bushwhack. Debian woody, emacs 20.7.2. Any ideas? Bill.

Re: [Zope] Web mail with POP3

What do you mean, 'pop3 support'? If you want people to access their mailboxes both through the web and from a pop3 mail client, then all you need to do is use a mail server like UW-imap which speaks both pop3 and imap. Then you can just stick with WorldPilot, for now at least. That's what I do, anyway. seb. ----- End forwarded message -----
