A precondition is a method or document which is executed before the File is viewed or downloaded. If the precondition raises an exception then the File cannot be viewed.

[Zope] Sybase & Thread
Hi,I just wonder if anyone can help me with my problem. Recently, I've been working on creating a ZOPE product which requires periodic access to my Sybase. I have created a thread process using the Threading module. There is no problem of periodically wake up the thread and print something to the screen. So, I guess I have no problem with thread programming under ZOPE. However, when I add some database related routines to the thread, problems started to occur. I sometimes got '... not connected to the database'. When I did an SQL 'update', nothing has been updated on the database server when I actually looked into the database using isql. After a whole day of trial & error, now I've got 'ZOPE Memory Error'! I just wonder what has gone wrong. I really have no clue and my deadline is pressing :(1) I want to know what is the proper way of using thread under ZOPE.2) Is there any critical limitation of SybaseDAv2?3) Can SybaseDAv2 & Threading live together happily?4) What the role of ZODB in such situation?Thanks a million if anyone can help!Regards,Nick

This is easier than you might think:-
Step 1: Do not register your 'sub' class(es) in your __init__.py
Step 2: In your container class import your sub class manage_add function(s)
(not sure if this is really needed, but, I do it for completeness).
Step 3: In your container class add:-
meta_types=({'name':'Sub Product', 'action':'manage_addSubProduct'},) # Sub-ob
ject types that are specific to this object
You can add as many as you like...
Step 5: Optionally add a meta_type to your sub class (if you haven't)
Step 6: Optionally add icon='thisIcon.gif" into your sub classes so they get
pretty icons.
Copy over new Product, and Restart Zope :-)

[Zope] LoginManager and ZPatterns - Sparse Install Docs, Help.
Zopistas, Maybe I'm making this harder than it needs to be. I want to set up a membership system for the site I am developing with Zope. I do not want to "restrict" any part of the site - instead I want a user to login (at their convenience) and then extend the "menu" options based on their group membership. If a user is not logged in - no problem, they just won't be able to view the advanced options - they'll still be able to surf the site (I want to maintain my user list in an external database as well). What is the best tool in Zope to accomplish this? After searching the site, I find there are several products - ACL Users, GUF, and LoginManager. Is GUF deprecated (The intro tends to give me this feeling)? Is LoginManager the way to go? It also appears GUF is more tailored toward restrictive authentication (I've already perused the "Using GUF with an SQL Database" how-to). I want a user to login (via HTML form/cookie) whenever they like, and get presented with additional menu options (based on their AUTHENICATED/GROUP status). Not have them try to access a "restricted" page (or type "manage") and get a basic authentication login box to get in. As far as LoginManager itself is concerned, I assume it requires ZPatterns. However, the Zpatterns install instructions are *very sparse.* How do I get the thing set up? Here's verbatim from the ZPatterns docs: - After unpacking the ZPatterns product, you will need to build this [c] >extension using the included Setup file in the ZPatterns directory. - How do I use the "Setup" file?? With the command "python Setup"? It doesn't say *how* to use it. - Please follow the standard procedures for building a Python module on your platform. (On Unix-ish systems, this usually consists of copying a Makefile.pre.in to the directory, then doing a make -f Makefile.pre.in boot >followed by make. - What are these standard procedures?? I built Python itself with "configure|Make|Make install". Where do I get this "Makefile.pre.in" file in the first place, from my Python src/build directory?? Correct me if I'm wrong, but there's usually some kind of script file to run that get's things going, or a "configure" script. I find none of this in the lib/python/Products/ZPatterns directory after I untarred it. So, I'm basically stumped. It doesn't appear GUF will do what I need, and I have failed on multiple attempts to get Loginmanager/ZPatterns installed. If someone could point me in the right direction on this I sure would appreciate it.

I found a mail that says I should run Zope single-threaded when using MySQL: http://lists.zope.org/pipermail/zope/1999-July/006487.html Checking my installation, I find I have no threading option activated, which means I'll be running the default number of 4 threads.

[Zope] server instability: ZODB corruption?
I'm hunting down an arcane problem in one of our Zope sites and find
myself hitting new and wildly diverse problems every day. I hope
somebody can point me in the direction of some solution strategies.
Main suspect is a corrupted Data.fs.in file. How can I audit and
repair it?
problem A: access denied vs. KeyError
For starters, we built a website with a lot of custom programming. I
created the NFGnav product
http://www.zope.org/Members/gyst/NFGnav
and my partner built a collection of ZClasses.
All this was Tested And Working Fine (TM).
Since some weeks, part of the site gives an 'access denied' error. We
had to shut down that subtree. Strange thing is, it also gives access
denied for the manager/owner logins of the site - that's me and I
really have access to everything. What is even stranger, is that when
I logon as superuser, I get a KeyError instead of an access denied
error.
=> Question: which parts of zope would be prone to denying access to a
privileged user, while generating KeyErrors for the superuser?
problem B: hanging zope thread zombies all zope sites
While debugging this problem, I found a strange correlation with
another problem we're having: zope threads consuming 99.9% CPU. Now
and again, a zope thread hangs. All zope sites are dead. I have to not
only restart zope; I have to stop zope, restart apache, and start zope
again to get rid of the hanging thread and get the zope sites alive
again.
As soon as I start digging around in the buggy site, the number of
thread crashes jumps up. In combination with the problems we're having
with that site itself, this suggests two possible causes:
1) ZODB curruption. We've had a complete server crash 3 weeks ago and
it is quite possible the ZODB isn't 100% healthy. In my zope
installation I found a utility 'bbb.py' to audit data storage
files. Alas, it is of no use:
| zeno:/usr/lib/zope/utilities# python bbb.py
|/var/lib/zope/import/www.intratuin.nl.zexp
|
| The input file is not a ZODB 2 database file.
| This script only works with ZODB 2 (BoboPOS) data or export files.
=> Question: is there another utility for checking and repairing
object stores?
2) Another possible cause would be an infinite loop in one of our
custom scripts. To try and debug this I wanted to import a copy of the
offending site into one of our testlab machines. However, on importing
the zexp file I got:
Error Type: TypeError
Error Value: ('len() of unsized object', , None)

In the Squishdot Product I discovered this:
Readme = Document('', __name__='')
Readme.__roles__ = None
This one seems to add a README tab. If you have a README.txt file in your
Products directory it displays it.

For unknown (but strange) reasons, at least earlier Zope versions (up to 2.1.6), sometimes place the URL of the missing resource into an HTML comment. Therefore, you will not see it in rendered problem report, only in its HTML source. Thus, follow the hint: tell your browser you want to see the HTML source of the error report.

Someone else already told you, that you must create a parameterless method (it need not necessary be named "PrincipiaSearchSource") that returns the files content. You may not need to keep the rendered version around but may be able to extract the plain text on demand. I think, there is a "word.dll" that provides access to MS Word from applications. Alternatively, you could control Word via COM.

[Zope] Zope in single thread mode during DTML rendering
A collegue of mine succeeded today to implement an infinite DTML loop. That happens ... However, during this loop, Zope did not respond to any request. Effectively, it was in single thread mode. Zope 2.1.6 Binary Distribution for Sparc Solaris 2.6 ZOracle DA, DCOracle, Oracle 8.1.6 After several minutes, Zope reported an "infinite recursion in document template" and the world awoke from its sleep. I was unable to reproduce this at home, though: Zope 2.1.6 Source Distribution on Linux 2 No database connections. Hugh, I have been lying: I just removed the "-D" from the Linux start script, and Zope blocked during the infinite loop. The behaviour is not related to the "-D" set or unset. It just blocks sometimes and at other times, it does not.

Almost surely, the "in" tag does not call a callable object (because it does not expect, they could be callable). You, therefore, get the method itself. It is identical for all records.

[Zope] Confusing "sqlvar" error message
Today, I analysed a confusing error message from "dtml-sqlvar".
SQL query template:
reported: "missing input variable: _[name]"
Of cause, I did not expect that such an input variable should
be necessary and I suspected the DTML parser not to
see the "..." around "_[name]".
After analysis, the explanation was simple:
SQLVar.render is a bit stupid in its error handling:
try:
expr=self.expr
if type(expr) is type(''): v=md[expr]
else: v=expr(md)
except:
if args.has_key('optional') and args['optional']: return 'null'
raise 'Missing Input', 'Missing input variable, %s' % name
This error handling is only senseful for "type(expr) == type('')",
i.e. for plain variable access.
For true expressions, the original exception would be
*much* more useful.
In my case, unwrapping the "try ... except ..."
produced "KeyError: FOLLUP_UP",
an obvious type (FOLLOW_UP rather than FOLLUP_UP).
Thus, the above exception handling should become:
except:
if args.has_key('optional') and args['optional']: return 'null'
if type(self.expr) != type(''): raise
raise 'Missing Input', 'Missing input variable, %s' % name
I will put it into the collector.
