Performance related to content loops/depth
by Granzow, Doug (NCI) 07 Jun '02

07 Jun '02

Bear with me, I'm a sysadmin, not a developer. I'm maintaining a Zope 2.5.1 server with Python 2.1.3 on Solaris 7. We recently upgraded from Zope 2.3.1. I'm seeing a problem where, occasionally, a bot will come along to index our site and suddenly Zope stops responding to all requests. It looks like what is happening is that the bot finds a loop in the content where each time you click on a link, you are returned to the same page, but the URL has one more level of depth. For example, I see requests in the log file for things like this: siteroot/info/catalog/catalog/catalog/catalog/catalog/catalog/catalog/catalo g/catalog/catalog/catalog/catalog/catalog/catalog/catalog When a bot hits this it keeps going deeper and deeper until we deny access to the bot. When I request a URL like that in my browser, even just one time, Python's CPU usage shoots to near 100%, and stays there for several seconds. If I keep clicking on the link to go deeper, it doesn't take long for it to effectively become a denial of service attack, because the processing time required to process each request seems to grow more and more as you go deeper. Is there any way to stop this from happening? Obviously we want to remove loops like this from the content, but as I said, I'm the sysadmin, not the developer. Any input is appreciated!

making authentication permanent?
by John Doe 07 Jun '02

07 Jun '02

Hi, I would like to make authentication permanent (ie once successfully logged in, no relogin required after closing browser). I've set the 'cookie lifetime' to 600 days but this does not seem to help. Anyone knows how to achieve this permanent authentication?

Product seeking products: how?
by Terry Hancock 07 Jun '02

07 Jun '02

Hi all, I need to create a plugin architecture for a product I'm developing, since I want to encourage third-party contributions, and define a clean way for them to work together. Given that Zope already has a nice plugin architecture, AKA Products, it seems like the most logical solution is to use that. Thus, my plugins would just be Zope products which implement a certain interface. But it is unclear to me how best to go about finding them. It seems like the most plug-n-play way for this to work would be for my product to collect all the plugins when Zope restarts -- but there are some problems, such as how to run code after all the other products have loaded. Is there any example code I should be looking at to do this (i.e. other products that behave like this)? Thanks, Terry -- ------------------------------------------------------ Terry Hancock hancock(a)anansispaceworks.com Anansi Spaceworks http://www.anansispaceworks.com ------------------------------------------------------

nested <dtml-in ...> statements breaking
by Donald Braman 07 Jun '02

07 Jun '02

I have nested queries using dtml-in statements. The outer query performs a broad query based on a number of variables and returns a number of variables for several records. The inner query performs a dtml-sqltest on one of the variables returned and returns another set of variables. (Or at least it is supposed to.) The only variable that two queries share is the variable on which the inner query performs the dtml-sqltest. The inner query gives me a key error, asking for a variable supplied by the outer query. Strangely, the inner query works when nested within a query that returns a single record using the same dtml-sqltest as the inner query. Any pointers on how to manage this?
