PyGres DB Connection in Zope drops when many Users are added (UserDB) (UserDB)
by Stephan Richter 25 Apr '00

25 Apr '00

Hello everyone, This is a help message to every mailing list, I think this issue could be related to. We are in production and 5000 flyers (45000 follow) were sent out and the site keeps giving problems. I use: Zope 2.1.4, PyGres 2.x, Apache, and PostGres 7.0RC1 The issue: It seems like that whenever "many" (10, I know that is not much) people sign up at the same time on our Web Site (http://www.plandepot.com) we loose the DB connection. The connection is simple restored, when disconnecting and the reconnecting the database. Unfortunately I was unable to reproduce the error outside of business hours, so I had never the chance to inspect the issue in detail. I personally do not think it is PostGreSQL or Zope, since I would have read more about it. I have to mention, that PyGres is not thread safe and by default Zope uses more than one thread if required. So could that be the issue? How do I setup Zope in a way, that it uses only one thread? Also, I do not use any of the caching features in Zope SQL Methods either. Any ideas are appriciated.

Advice on Discussion-based products
by Alexander Limi 25 Apr '00

25 Apr '00

Zopistas, I would like some advice on choosing which product to use in my implementation of a discussion board on my site. We run a site much like mp3.com, where we host music for artists free of charge. The requirements are roughly this: - People should be able to comment on individual songs by an artist, also rating the song from 1-6 as they post their opinions (kind of like a mini-review) - The discussion threads should be collapsible - Only logged in users should be allowed to post comments Should I go for Confera? ZDiscussions? Parts of the Squishdot code? Are there any other alternatives in addition to these? I heard some people experience crashes and lockups when they used ZDiscussions on their site, any advice on this? Thanks in advance, Alexander. (Please CC me if you answer to this mail)

How to stop users uploading large images
by Steve Alexander 25 Apr '00

25 Apr '00

Hi Folks, I want to allow ordinary, low-privalidged but non-anonymous users of my site to upload small images. I can use PIL to scale images that are slightly too large. However, I want to stop users abusing the system by uploading 100MB images to see if it will crash the system. What is the best way of doing this? Can I modify the _read_data() method of lib/python/OFS/Image.py to read some kind of maximum-size attribute, and abort uploads that exceed that size? Alternatively, perhaps this is something I don't need to worry about. Maybe the ZODB has a graceful failure mode on extra-large uploads. -- Steve Alexander Cat-Box limited

Edit DTML Document content and properties in one form
by Sin Hang Kin 25 Apr '00

Can I edit the DTML Document and its properties in one form. Can this be extended to Zclass? I find that I always forgot to modify the properties. I hope making them into one form will help this. Rgs, Kent Sin

Zope fine tuning HOW-TO / Zope Performance
by Felipe E. Barousse 25 Apr '00

25 Apr '00

Hi all: We are relatively new to Zope. I have found problems related to performance issues. Even though it is known that Apache alone is much faster than Zope, and when migrating (even static pages) to Zope a performance degradation may be expected, the differentials we are getting are very significant. Forget it when we add the dynamic parts. My question is: Has anyone seen a Zope fine tuning guideline. ? It would be interesting to have something like a cookbook on Tuning Zope and the overall web serving environment for specific cases. I am using RH Linux 6.1, Zope, PostgreSQL...all latest versions. As of hardware, at the minimum we have Pentium III, 128 MB RAM. As of now, very few hits but slow response though. Also, any names (URLs) of high traffic sites that are currently running Zope and serving dynamic content would be appreciated. Thanks Felipe

How does one access a ZClass property from a ZClass method?
by Michael Grinder 25 Apr '00

25 Apr '00

I have a ZClass with a property sheet that contains two properties. I then created a method for the ZClass that tried to access the properties. For example: I created a property sheet that contained a float property named "high". I then created a DTML memo in the methods section of the ZClass. But when I put something like <dtml-var high> in the method, I get a KeyError saying that high doesn't exist? Obviously, I'm not understanding something somewhere. What am I doing wrong? ---------- Michael Grinder grinder(a)cs.montana.edu "Well, I've wrestled with reality for 35 years, doctor, and I'm happy to state I finally won out over it." -- Elwood P.
