Inheritance and the Search Engine : A Tragic Tale of Romance
by Edward Pollard 05 Sep '03

05 Sep '03

Greetings Zopers, I've got a quandary that I would like to solicit wisdom on. We are running Zope 2.6 as part of our website. Our central search engine that spans all our websites is running on ht-dig. Inheritance on zope is sending our search engine on infinite traversals of the Zope tree. This is caused, as you can probably guess, by relative linking (eg '../../blah.htm'), and one ill-formed url somewhere that gets the recursion started. This is not good. Now, I'm trying to create an environment where people can port their websites from the old non-templated world to the new Zope-templated one. However this necessitates a tolerance for bad coding, at the very least a tolerance so that one idiot with a (trivially) badly formatted url does not cause our search engine database to become somewhat close to useless as the same page is listed at 1000 distinct urls. Of course that just utterly destroys word search heuristics. It being my opinion that I'm not doing something completely batty and unusual, I thought there might be someone out there with greater understanding with which to enlighten me. Thanks for your time, --- Edward J. Pollard University of Lethbridge Web Development

acl_users

Hi Am I right that there is no extense documentation about automatic user creation and authentification in dtml-methods. I haven't found any. There is some little info about the variables and methods and I also found some discussion about it but I didn't success with that. For the use of a conference registration I want the applicants to be able to modify their indications after they subscribed a form. So I tried to create a user (with success) and authenticate him within the same method (without success). To create I use: ----------- <dtml-call "REQUEST.set('name',_.string.join([REQUEST.form.get('email')]))"> <dtml-call "REQUEST.set('pwd',REQUEST.form.get('last')+_.str(_.random.randint(0,9)))"> <dtml-call "REQUEST.set('password',pwd)"> <dtml-call "REQUEST.set('confirm',pwd)"> <dtml-call "REQUEST.set('roles', ['approvals'])"> <dtml-call "REQUEST.set('domains', '')"> <dtml-call "acl_users.manage_users(submit='Add', REQUEST=REQUEST)"> ----------- to confirm within the same method or after clicking a submit button, there seem to be different possibilities: ----------- DTML-Method: <dtml-call "acl_users.authenticate(name, pwd, REQUEST)"> <dtml-call "acl_users.autorize(name, pwd, REQUEST)"> Python-Script: security.validate(access, container, name, value, roles) ---what means 'container' and 'value'??? ----------- Thanks for any hint!

Scripts run as least privileged user necessary?
by Ken Causey 05 Sep '03

05 Sep '03

I'm running into a strange problem. I have a situation in which I want a script to treat Managers differently than other users. But I'm finding that whether or not I'm logged in as a manager or not the script only considers the user to be 'Anonymous User' as long as 'Anonymous' has View privilege for the script. If I change the Security permissions so that only 'Authenticated' can View the script then the user is properly identified. Is this expected behaviour? This is what I'm seeing on 2.6.1. As a test create a script with return _.SecurityGetUser() be sure to bind '_' to Namespace. Set that script so that the View privilege is allowed for 'Anonymous'. Stay logged in and run the script. Then change it so only 'Authenticated' as the View privilege, run it again. The behavior changes based on the permissions. Ken Causey

What happened to MetaPublisher?
by paulporter＠buffalotalks.com 05 Sep '03

Does anyone know the status of MetaPublisher? It was put out by Beehive in Germany but their web site doesn't seem to exist any more. It was www.beehive.de. If MetaPublisher is gone is there anything as good or better available that someone could recommend? Your input is greatly appreciated. Paul

Problem with http-logging in Zope 2.6.1
by Charlie Clark 05 Sep '03

05 Sep '03

Hi, I've noticed there is a problem with the http-server log in Zope 2.6.1. I've also noticed I'm not the first to notice this. 2.6 betas seem to contain the fix but I'm loathe to update my productive system. I've traced the error medusa/http_server. Is is correct simply to remove the offending double space in the logging string? ie. self.channel.server.logger.log ( self.channel.addr[0], ' - %s [%s] "%s" %d %d "%s" "%s"\n' % ( name, self.log_date_string (time.time()), self.request, self.reply_code, bytes, referer, user_agent ) ) becomes self.channel.server.logger.log ( self.channel.addr[0], '- %s [%s] "%s" %d %d "%s" "%s"\n' % ( name, self.log_date_string (time.time()), self.request, self.reply_code, bytes, referer, user_agent ) ) Thanx very much Charlie Clark

An intro to vice posting policy..
by Børge Kjeldstad 05 Sep '03

05 Sep '03

Hi, I have just been noticed I posted my messages in html. I am realy sorry for this. I did not know I did, and did not even know what posting in html was. However, now I have pressed som buttons in the email program and I hope it is now ok. Please tell me if not :) Now, having become aware that I was misdoing, I looked for some guidelines on vice posting policy. The intuitiv places to look were: 1. The welcome message I received when I subscribed to the zope list 2. The webpage were I administrate my member options 3. The zope.org/Resources/MailingLists page Unfortunately I found no such guidelines on these pages. My question is then: Would it be beneficial to have some such guidelines on one or more of these places? To many members such guidelines are surely not needed, but for some they may be of help. I see at least two possible ways to include such guidelines on one or more of the three places mentioned above: 1. Simply just include a link to some site on the internet were vice posting policy is described. 2. Make a checklist and have a link to it. The checklist could be like this: - Edit your subject line to avoid ..... - Do not post your messages in html. To confirm that you do not, do the following: ..... - Edit message body when replying. For instance you should cut away... - - - etc. Best! Børge

Hyperthreading is only virtual processor not physical. In Linux with smp kernel that know HT features you get only 5-30% increase in computing power depends on kind of computing. So you could be quiet with Zope, if Zope will be boound in CPU0 then system consume power from CPU1. > Say you have a dual-processor HT machine, running two Zope.

Will this configuration perform > better? I think that you will get most performacne with two Zope instances. HT technology is only moneymakers marketing tool for thumbs. If you want best available performacne for low price (ie., does not use processors targetted for servers), use dual P-III Celeron CPU instead of dual P-4 with HT, you will get much more performance with this oldies but goldies...
