Hello list, are you there? Sorry, but I haven't had any mail from the Zope list, Zope-Dev list and the ZDP list for over 3 and a half hours. And I don't trust such quiet.. =) -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-6254545 Fax: +31-35-6254555 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

Re: [Zope] Newbie install help needed !!!!!
by Robert OConnor 18 Mar '99

Hi Thomas, >Is there anyone that could help or give me some pointers ? Yup, those switch options are confusing so I avoid them ;-) First, the most helpful tool for me in working with Linux is "git". This is a nice character based navigation and file management utility. Just type git. It came on my RH Linux and is installed automatically without your request. This program is alot like the DOS Norton Commander that I started using years ago. So you get the distribution: Zope-1_10_2-linux2-x86.tgz I use git's F6 key to rename it zope1102.tgz to ease the long typing. Move it to a newly created directory (F7) named perhaps "zope". Then in that directory, type: tar -xvzf zope1102.tgz A new directory is then created under your new zope directory named: Zope-1_10_2-linux2-x86.tgz/ Go into this directory and type ***This is were you got stuck*** ./install ***No switches!!! Then edit the access file now in this directory and change the obscure username and password to your favorites with F4 key to use "vi" Press i to insert new user/passwrd -- example: zope:gogo Press escape then :wq to save. Then ./start to start zope and maybe later if you EVER want to stop zope (who would ever WANT to stop!, ./stop. BTW, if you want to test the integrity of the downloaded zope distro, only change the t to an x as in: tar -xvzf zope1102.tgz Enjoy!!! -bobo connor

Python freezes in lwp_sema_p()
by Andreas Jung 18 Mar '99

18 Mar '99

We are running Python1.5.2b2 (with thread support) , latest DCOracle, Oracle 7.3 under Solaris 2.5.1. Some of our applications hang in about 10% when they run. We trussed the binaries and discovered that they all sleep in a lwp_sema_p() call. Python/thread_cthread.h seems to mention a problem with the Solaris PThreads implementation however I can't figure out if this is the real problem. I am not sure whether it's a problem of Python, DCOracle or the Oracle libraries. Any ideas or comments ?

Zope LDAP Products available (v0.1)
by Anthony Baxter 18 Mar '99

18 Mar '99

Short Version of message: ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from http://www.interlink.com.au/anthony/python/ I'm looking for opinions on the LDAP zope product I've been building. Right now, LDAP connections work, LDAP Methods work, but there's still a bit more to do. Right now, the following is unimplemented: In ZLDAPconn: . Anything other than simple_bind(who, passwd) for connecting to the LDAP server . meaningful doc strings In ZLDAPMethods: . Pluggable Brains . Result Caching . Limits on the number of results . Variable interpolation in the filters, and in the base DN . modify or add queries (only search is supported right now) . meaningful doc strings :) Other stuff: . UserLDAP is not finished yet (or released) - the primary issue is the storing of roles and domains. Right now this would have to be some non-standard LDAP attribute... but what should it be? It also probably needs modify and add added to ZLDAPMethods before being really useful. Things I'd like comments on: For ZLDAPconn: what other bind methods would you like to see? For ZLDAPMethods: how should add/modify/query be distinguished? Separate methods? I had planned to get variable interpolation working tonight, but decided I'd rather get an early night. Probably tomorrow evening, instead. Stuff I hope to get going in the next day or so: variable interpolation, pluggable brains. Anyway, ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from http://www.interlink.com.au/anthony/python/ It requires David Leonard's ldapmodule, from http://www.it.uq.edu.au/personal/leonard/dc-prj/ldapmodule/ It's been tested on Linux 2.2, under Zope 1.10.2 and ZServer. Assuming the ldapmodule works on other platforms (it's available in source, and also as a windows .pyd) it should work elsewhere, too. Anthony

ZAP
by Shaw, Howard 18 Mar '99

18 Mar '99

How can I configure ZAP so that all http requests go through the cgi? Zope is the only thing running through this apache, so I don't want everything on the site prefixed with Zope/ (or anything else, so no, I don't just want to know how to change the prefix). This is basically what is keeping me on ZopeHTTPServer. BTW, running ZopeHTTPServer multi-threaded worked well for about 15 minutes. Then suddenly certain pages wouldn't load. I stopped and restarted the server, but the pages still wouldn't load. I also noticed that if I stopped Netscape and hit reload, it would cause several new ZopeHTTPServer instances to appear, and doing so again would continue to create new instances which never seemed to dissappear. Are these locking the items they are downloading? The behavior I saw seemed consonant with it locking the item it was downloading, then failing to recognize the netscape had disconnected, and thus never removed its lock. When I restarted it single-threaded, all the pages came up without a problem. I would really like to move to Zap, but I can't afford at this point to have the URL of the page change. How can I make a Zope pcgi accessible as the root of a Zap install? Please help. Howard C. Shaw III Programmer/SysAdmin St. Thomas High School

multiple trees
by cimarron＠taylors.org 18 Mar '99

18 Mar '99

There seems to be a problem with DTML documents which uses more than one  ..  sections. I'm seeing a python error when attempting to expand any node of the second tree. I'm going to try and fix this on my own as a way to familiarize myself with Zope internals but I thought others on this list might want to be aware of the problem and/or provide information about their own experience with multiple trees.

Newbie install help needed !!!!!
by Thomas Schruefer 17 Mar '99

17 Mar '99

Thus far my attempts to install the Zope binary release on a Linux machine have been for nothing. The Install documentation and the Install program contradict each other at almost every turn. The docs say use ./install -u <userid> but the -u switch is gives a error message, saying it is a invalid switch and not supported at all. The install --help, says nothing about a -u switch. The docs say you can specify the cgi directory, with the -c switch, but the install program says that is a unsupported feature. The -s switch in the docs says this is to provide the superuser login and password to the install routine, yet the install program say this is used to strip tables (perhaps parsing the access file), none of the docs say anything more. I have tried numerous variations, all to no avail. Perhaps the ZDP should have started at the beginning, with usable install instructions, instead of with a FAQ. I must say that the screen shots in the PDF file and those docs are quite nice, but thats about it. Reading the PDF docs, just makes me want to get in and try Zope even more. Is there anyone that could help or give me some pointers ? Tom

Newbie questions
by Rankine, Alastair 17 Mar '99

17 Mar '99

Hi Zopesters, I'm trying out Zope for the purpose of getting a book catalogue on the web. So far, I'm extremely impressed with it! Of course, I have some questions. (For the record, I am running Zope 1.10.2 with Apache 1.3.something on a MkLinux DR3 box, administered with IE4 on NT). 1. When you edit a DTML document using the Zope management interface and hit the update button, Zope goes away and tries to parse it to ensure that it's consistent DTML. If this fails, you are left with no option but the browser's back button, which, under IE4 anyway, seems to discard the changes you made to the document. Is there a fix or workaround (besides ctrl-A ctrl-C before clicking the update button) for this? Us newbies write lots of bad DTML :) 2. When a folder acquires an index_html document from further up in the heirarchy, the  tag refers to the title of the index_html document, rather than the folder being displayed. How do you write the index_html document to display the title of the acquired object, rather than the index_html document itself? (Hope this is clear) 3. Finally, I need some advice about how best to lay out the website. Basically I'm trying to build a site containing a book catalogue. Here's what I've got so far: + Root + Titles [folder] - index_html + OriginSpecies [folder, title: "Origin of the Species", desc: "blah", author: "CharlesDarwin", year: 1854] - cover [image] + DiamondAge [folder, title: "The Diamond Age", desc: "blab", author: "NealStephenson", year: 1995] - cover [image] ... + Authors [folder] - index_html + CharlesDarwin [folder, title: "Charles Darwin", bio: "..."] - photo [image] + NealStephenson [folder, title: "Charles Darwin", bio: "..."] - photo [image] Hope the notation is clear enough. What I want to do is "link" the titles to their authors and vice versa. So the index_html document for Authors would display the author, their picture, bio, and a list of titles by them. A similar arrangement would apply for Titles. The author property of the title (*) links the title to author, but what's the best way to link backwards? Similarly, what's the best way to display the author's information for a title? All advice appreciated! Thanks. (*) assuming only one author for now

Re: [Zope] Impact of Zope on hosting provider?
by Jim Harris 17 Mar '99

17 Mar '99

I contacted NexusWeb yesterday and they said they would provide a setup for Zope, but no support. They were not specific as to the setup. They did mention they supported Python. I was going to write them back to see if they ran Zserver, or just provided the links to Apache. They did have msql and mysql. The minimum plan to support Zope was the 50MB/$20 a month plan. The other site was out of my price range ($50/mo). I just started studying Zope yesterday to use for a project I was planning to use Visual Basic/ADO/ASP for. I'm testing on a Win95 machine, but plan to move testing to a Linux box. I decided before signing up with a hosting server to wait for Zope 2, which I've seen a couple of references to. What's the deal on that? One place promised a better integrated web server. If Zope moves more torward being a totally self contained server, then I don't want to mess with Apache or IIS. -----Original Message----- From: Robert Wentworth <rhww(a)erols.com> To: zope(a)zope.org <zope(a)zope.org> Date: Tuesday, March 16, 1999 4:25 PM Subject: [Zope] Impact of Zope on hosting provider? >Right now my biggest obstacle to setting up a Zope-powered >site could be finding a hosting provider I have confidence >in who is willing to run Zope.

Hmm... the screenshot didn't seem to 'travel' too well, Guess you'll just have to install PIL to see it. ;) Cheers, A.
