I want the script to insert a link to a public library catalog that searches for

have to be invoked for every ISBN, I guess. I'm using CMFSin to get the feeds.

[Zope] Zope stops responding on hpux
Dear list-members
I am desperately trying to get our zope application run on hpux, and any
help is greatly appreciated. I have the following problem:
When I click on a tal-object ("Page Template") to edit it, then zope
stops responding. No error is logged, nothing. I even cannot stop zope
anymore with "zopectl stop" or control-c if started with runzope. It
seems that zope silently crashes... However, I can create a tal-object,
it only happens when I try to edit.

Any hint is greatly appreciated where I can look at or how I could debug
zope.

That's exactly what's happening at the moment; the WebDAV access is linked to via the web interface after they log in (it's only one small part of a larger system). They log in via the web, gaining a cookie which is passed to the Explorer 'web folders' thing, so when they click on the link to the WebDAV part of the site the cookie is still valid and they don't have to log in to WebDAV. * All I'm trying to do is boost the security of the system overall by ensuring an attacker can't simply sidestep the 'three login failure lockout' just by repeatedly trying to log in via WebDAV. mark * A thought occurs to me after writing it like this.

Well, in theory its possible if the client accepts cookie to just store the amount of wrong attempts via cookie (or id - which would be the same) and deny any password, be it even the correct one when it comes via basic auth. But I strongly believe this does not save from abuse because its just too easy to remove the cookie or just not accept it in the first place.

Re: [Zope] A memory leak in Zope, PageTemplateFile and macros?

Small memory consumption increases can be caused by an effect
known as memory fragmentation. The "C" runtime library (and Python
on top of it) does not support memory compaction. Therefore, free memory
areas can only be joined together if they are adjacent (and even then
memory management may not do it). As a consequence, the free memory
tends to be fragmented in a large number of small blocks.

The usual approach in investigating memory leaks works as follows:
* you flush the ZODB caches
("Control_Panel --> Database Management --> --> Flush cache
--> "minimize").
* you visit "Control_Panel --> Debug information" and
"update snapshot"
* you perform your test
* you flush the ZODB caches
* you visit "Control_Panel" --> "Debug information"
and analyse the changes in reference counts (in the middle
of the page).
This allows you to recognize leaks at the level of instances (of classes).
The "LeakFinder" product helps you with the above steps.
I did this for your case and could not determine leaking instances.
When instances of static types (e.g. strings, integers, dictionaries, ...)
leak, they cannot be detected in this way. Neither can
leaked caused by fragmented memory.
Python can be build in a special way to analyse leaks of
any Python objects. Note, however, that all "C" extensions
(especially Zope) must be then build in a consistent way.
Tracking down such leaks is even more expensive that
those involving standard Zope objects.
There are tools around to analyse leaks at the "C" level.
I had used the commercial product "purify" once (a long time ago).
Andreas (Jung) told me that some open source project (I think
it was KDE) has built a similar tool.

It would be very easy -- with the exception of people that run Zope as "root" (and later switch the process user). This silly silent logging during startup was only implemented to avoid problems occuring when Zope starts up as root and later switches. Zope could easily start logging as soon as it had read the configuration file and had seen that it is not going to switch users. >In debug mode (the default) Zope fails when a Product fails to init. >This is useful when running 'runzope' since you don't have to kill Zope. >Without debug mode, Zope will start up, but the Product will be broken, >and its failure listed in the Products section of the Control Panel.

Up to Zope 2.8, you cannot protect access to objects
of simple type (such the "title" attribute of type "string")
in an easy way.
Access to such attributes are dually protected:
By the "Object Permission" (set via "security.declareObjectProtected")
*and* the "setDefaultAccess".
"setDefaultAccess" can in fact take dictionaries and callables
as arguments. Read the Zope Developper Guide for the
types available for "__allow_access_to_unprotected_subobjects__"
and how they are interpreted.
"setDefaultAccess" just causes its argument to be assigned
to "__allow_acc...".

FWIW, the reason zLOG doesn't start writing to the log at an earlier time is that it waits until the process can switch effective users. If it didn't and Zope started by root (or another user that isn't the desired effective user), some log files might be written as root, and would become unwritable at a second startup (this used to be a FAQ before Zope 2.7 prevented it from happening). Probably some work can be done here to be smarter in cases where this doesn't matter. - C ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Is it possible to extend Zopes WebDAV authentication?
Web Folders pass cookies around too, FWIW, so it's probably not strictly necessary to use http basic auth. But without using http basic auth, there is no way to log in unless you have them go to the web interface first, then launch a web folder, so maybe impractical. - C On Sat, 2005-05-07 at 06:31, Jens Vagelpohl wrote: > On May 6, 2005, at 23:52 , mark hellewell wrote: > > > On 5/6/05, Tino Wildenhain <[EMAIL PROTECTED]> wrote: > > > >> Actually, it does not.
