[Zope] Simple function nightmare
Hi Zopistas, Hope you can help me .. (I'm hating DTML right now ) Take this dtml document with name: dontWork_dtml I want de document act like a function that concatenates a,b and c but if at other document i do something like guess what: it renders 2-2-3 That is d is not a string but an expression. The question is How the Fck. can i implement the concatenation of 3 arguments ? Gracias por vuestra paciencia. -- __ Felipe Alvarez Harnecker. QlSoftware.

[Zope] Virtual host admin under Apache+ZServer+SiteAccess

Greetings For security reasons, I would like to do web administration of remote Zope installations via ssh port forwarding. For instance, while running ssh -g -L 8080:foo.bar:8080 foo.bar one can access a ZServer on foo.bar:8080 using http://localhost:8080/. However, I'm using Apache with ZServer and SiteAccess for virtual hosting as documented in http://www.zope.org/Members/anser/apache_zserver, and this has a nasty implication: once I activate a SiteRoot inside some Zope folder "/parrot" for making it the top folder of a virtual host http://parrot.bar/, the use of URLs under http://parrot.bar/ is forced whenever administering content under the "/parrot" folder, even if arriving from a foo.bar:8080 document: the browser is then no longer connecting through the secure channel but talking directly with http://parrot.bar/. Of course this could also be redirected, but not so easily. In this example, it would be nice to be able to administer the contents of http://parrot.bar/ either via parrot.bar (typically for less sensitive content, end users) or via foo.bar:8080 (more delicate administrative tasks, administrators which know how to encrypt communication with ssh). Is there interest (or is it feasible) to make virtual hosting support evolve to allow this? (I didn't think much about the implications, but can already notice a problem under the virtual hosting strategy above (ZServer+Apache): how to make Zope "guess" if it should write absolute URLs for parrot.bar or for foo.bar:8080?) Even better would be web content administration under SSL, of course :) jmce: +351 919838775 ~ http://artenumerica.com/ ~ http://artenumerica.org/ ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] [announce] SQL Session 0.2.9 available.
A long-overdue update to SQL Session is out. This version (0.2.9) will be the last version in the 0.2.x series (assuming no brown paper bag bugs in this release). I will be now working on 0.3.x, which will hook into the transaction machinery so that it only makes a single set of updates in a transaction. This should lower the database hits significantly. Installation: If you have a previous version of SQLSession, you might need to go to the management panel of your Session object after installing the new version and hit 'Change'. Note that the default schema has changed to avoid bad words like 'name', 'session', 'sessions' and 'value', since some databases have issues with these. Changelog from 0.2.3: Code now uses it's own decodestring/encodestring, because the standard python lib supplies an incredibly stupid implementation. (take a string, wrap it in a StringIO, then pass it to encode which then pulls out the string again.) Rough testing shows that a small string encode or decode drops from 1ms or so to about 1/20th of that. Given how often this is done, it makes a big big difference. Jeff Hoffman supplied a patch that makes SQLSession work with 2.2 - adding __allow_access_to_unprotected_subobjects__ = 1 to the SESSION object. Ooo, magic. Changed the default schema and queries to avoid using the words 'session', 'value' or 'name'. Different databases have different ideas of which are and are not reserved words. Added a new option 'path', to specify the cookie path. This means that you can specify, say, /foo, and only the browser will only send the cookie when requesting URLs beginning with /foo. Re-did some of the internals to avoid what may or may not have been a refcount cycle. I'm still not sure what caused it - assigning the SESSION object to REQUEST.SESSION, with SESSION keeping a reference to the parent Session object. It now finds Session by acquisition. A number of dumb bugs were squished.

[Zope] images in access database
Hi, I would like to be able to have gifs/jpgs stored in an MS access database and then pull the out using zope and display them in rendered documents. I am completely new to access. I have successfully installed the ODBCDA into zope, and are able to connect to an access database and pull ordinary text data out of tables. I have created a table in access with a column of type 'OLE object' and put a gif image in as data. This is the only way I know how to get an image into the table. The problem I think with this is that it is a link to the gif on the HDD, and doesn't actually have the data in the table? Anyway, when I pull the data out of the table from zope, access puts a header and footer around the gif binary data, and hence a simple wont work to display the image. Has anyone else every pulled images from an access database. Will I have to write a method to strip the header and footer from the returned data before displaying the gif? terry. -- - Terry Kerr ([EMAIL PROTECTED]) Adroit Internet Solutions http://www.adroit.net/ 03 9563 4461 0414 938 124 ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] The Zope Weekly News
This week's ZWN covers the upcoming Open Source Convention, the forthcoming Zope 2.2, the PTK's further integration with the community and Zope.org's new community features and recent events. The opinions expressed in Zope Weekly news are solely the author's, and not the opinions of Digital Creations, The Zope Community at-large, or the Spanish Inquisition. The Zope Weekly News now has a "permanent home", http://www.zope.org/Documentation/ZWN. And Now For Something Completely Different: Open Source Convention Zope is going to have a strong showing at the "Open Source Convention", http://conferences.oreilly.com/oscon2000/, July 17-20, 2000 This conference should be pretty amazing. Guido von Rossum is giving a State of Python speech, Gregory Bendord is giving a futuristic keynote on the "Comfy Culture", and the Zope community will be there as well: o Ryan Huges will be "talking about worldpilot", http://www.oreillynet.com/pub/e_sess/725 o Paul Everitt will be talking about "the Zope-Mozilla Initiative", http://www.oreillynet.com/pub/e_sess/853 o Christopher Petrilli will be giving a tutorial on "Zope for developers", http://www.oreillynet.com/pub/w/python_tutorials.html based on the materials "taught at IPC8", http://www.zope.org/Members/petrilli/Presentations/ o In the "It's like Zope just not" department, Elaine Ashton is holding a Birds of a Feather to talk about how Zope's success isn't due to the inherent goodness of Python, and that "Perlers can do it too", http://conferences.oreilly.com/oscon2000/bofs/ Documentation Status -- by Amos Latteier I'd like to share some what Michel Pelletier and I have been doing to improve Zope documentation. * We conducted a poll to help us determine what was most needed. We found out that Zope docs are of middling quality and folks most want new user help. * We wrote an online help system for Zope and wrote help content for all management screens. Right now we are updating this content for Zope 2.2. The help system will ship with Zope 2.2 and an alpha is available right now. * We've started a Zope API documentation process. Right now there is an extensive Zope API documentation wiki on Zope.org. The fruits of this labor will be API docs that will ship with Zope in the online help system. Right now several API docs are complete and are included in the current 2.2 alpha. * We've overhauled Zope training materials and will make them available publicly in the next week or so. * We're still working on Zope Guides and References replacements. I think that the training materials will be quite useful for this effort. I hope to have Guide and Reference replacements done by the end of the summer. Zope Status -- by Brian Lloyd Summary o Lots of collector issues were completed for inclusion in 2.2 beta. o All of the hard thinking for the remaining todo list for beta 1 is basically done. Now its a race to the finish line :^) Last week highlights 20 collector issues were fixed last week in preparation for 2.2 beta, mostly issues that pre-date the 2.2 alpha release. Kudos to this week's MVPs who submitted patches and helped to diagnose bugs and test fixes: o Toby Dickenson contributed a patch to speed up Zope startup. o Itamar Shtull-Trauring and Chris Withers tracked down a problem with image caching that affected certain versions of Netscape browsers. o Phillip Eby helped uncover a problem with double aborting of objects registered with the transaction machinery. o Itamar also sent a patch for Netscape misfeature that recognizes Windows extended ISO Latin-1 characters as HTML delimiters which would have slipped by HTML quoting. o Anthony Baxter and Kevin Dangoor helped track down a problem with importing in the 2.2 alpha release. o Shane Hathaway did some much-needed work on the DateTime module. Many folks also participated in a discussion of a proposed Observer interface to support event-based designs (like email notification) in Zope. There is now a proposed set of Observer interfaces on the "interfaces Wiki", http://www.zope.org/Members/michel/Projects/Interfaces on Zope.org (and there was much rejoicing). Next week Finish up outstanding issues and get a 2.2.0 beta 1 release out. The outstanding issues to finish before the beta are: o Changing how ownership is handled for move / rename operations. Ownership info will not change for move or rename operations, and a new knob will likely be added to the "import" screen so you can choose to import objects with their existing ownership information intact. The online help for ownership will be updated accordingly. o Some basic hooks to support virtual hosting (a la SiteAccess) have been designed and will be added to allow product auth

Re: [Zope] Form POST Question (and a QUERY_STRING Q.)
> Is there a way for me to get the raw posted data and forward that

What I ended up doing was following Zen's suggestion and creating an
external method that basically does (not an exact quote; it's on another
computer):
def generateForm(self):
outForm = []
for (name, value) in self.REQUEST.form:
outForm.append ('' % (name,
value)
return string.join (outForm, '\n')
It's a little more than that, but I don't have it in front of me. (this
wouldn't deal with quotes right).
I haven't run into the name="mynum:int" problem yet, but maybe that's
just luck, or maybe it's just because of my particular forms. The bad
part is that I don't know of any way to pass POST data on a redirect
(anybody know how to do this, or is this impossible?), so for now I just
have a form that's nothing but a Submit widget with all the other dat a
hidden.
You can of course change it all into GET data and just join them
together using:
'%s=%s' % (url_quote_plus(name), url_quote_plus(data))
and joinging with &, in which case you actually can do a redirect, but
presumably someone made it POST for a reason, so I'm not going to mess
with it. It's an inelegant solution and might not work for everything,
but it's all I have for now!

> Some alternatives we considered and didn't go for: > - write something in Zope to listen for SMTP connections, effectively > large portions of an MTA. This would be cool but painful. Providing a basic SMTP server is not at all difficult to do in Python. I did a cut-down one once as part of a test system, and extending it would be straightforward (the cut-downness was not in structure, just did not bother to implement the SMTP commands I did not need - the underlying design was a state-machine [natch!] - however one problem I did come across was that it was not possible to implement the state machine completely from the RFC, which contains ambiguities). Some potential troublespots in re-visiting this work: - error handling, if done properly, might cause some problems (the state machine helps a lot here, but I cannot guarantee that I did not miss something obvious) - emails nowadays can be very large, with MIME encoded movies and stuff. Each received email has to be stored somewhere - can we (would we want to?) reliably store this kind of data in the ZODB? > - pull mail from a POP or IMAP server. This had the downside that it > introduced polling into the system (slow) and also required something > to happen on a schedule, which doesn't happen in Zope yet. Funny you should mention this. I am considering moving my domain from the current ISP to a friend's server. One of my current ISP's services that I use is webmail, so I was looking at how this could be done after the move. Sending mail through a web interface is a doddle, but what about viewing received emails? I had got as far as realizing that something could be built on Python's support for POP3 - use POP3 to collect the headers of currently available messages, create a web page displaying them, with each entry linked to a page that would download (without deleting) an individual email. I think that my current ISP's webmail system must be doing something like this. So far it looks fairly straightforward to implement.

[Zope] [announce] MountedFileStorage product - mount multiple ZODBs.
I've bolted together a simple Product which allows you to mount sub-ZODB's through the zope management interface. http://www.zope.org/Members/anthony/software/MountedFileStorage/ (it's now up to version 0.01 :) It _requires_ an up-to-date CVS version of Zope. It won't work on 2.2a1. I'd expect it will work on 2.2, whenever that happens. Most of the credit for this goes to the guys at DC who did all the work - but any bugs are probably in my bit, not the bits they did. Anthony readme follows: Created by anthony. Last modified on 2000/06/01. Ok, so the DC guys have been talking about allowing multiple ZODB support, but I couldn't see a way to use it. A bit of trawling through the CVS and I found the guts of a MountedItem object which has now been removed. Using that as inspiration and a source of pointers, I've bolted together a really simple Product for mounting multiple ZODB files onto a Zope installation. You should also check out the MountedDatabases section of the ZODB Wiki. First of all, you need to be running a really really recent CVS version of Zope. 2.2alpha1 isn't good enough. Then install this product (it unpacks in lib/python/Products/MountedFileStorage). Sample usage: cd $zope/var ; cp Data.fs.in nifty.fs Select Mounted FileStorage from the product add list. For file put nifty.fs. Leave path blank, and put whee as the id. You've now got a copy of the default Zope install mounted. In the same session, add a new Mounted FileStorage, for the Path put in QuickStart/Outline. Leave id blank. You've now mounted the QuickStart/Outline folder from the mounted FS as Outline in the current folder. WARNING: This is really really untested stuff. It Works For Me. Not To Be Taken Internally. Do Not Come Crying To Me If It Breaks Your Zope Install. If you want to play with this stuff, you really should back up your Data.fs first. Security Issues: There probably are some. I've no idea what they might be. The product makes a really simple-minded effort to not allow badness through (any filename with a / or \ in it). Don't give access to the permission Mount FileStorages to anyone that you don't trust, though. Note that this includes anyone with Manager role on the system. Note also, though that you can only mount existing files that are in var/. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

There seem to be a variety of reasons for pgi_wrapper to hang on
NT. In my case, running behind Netscape it hangs when someone
requests an objects and then closes the connection before the
object is sent back from pcgi_wrapper to the Netscape server. In
this situation it appears that Netscape fails to close the pipe, but
never reads from it.
I think there may also be a situation where the NT version can hang
if Zope throws an exception within its handling of the pcgi request
(pcgiReadSocket checks its result only for SOCKET_ERROR
whereas pcgiRead checks for any error or for a 0 return). When
Zope throws an exception it can close its socket without writing the
data and the recv call then repeatedly returns 0. You should be
able to tell if this is the problem because the hung pcgi_wrapper
will be consuming all available CPU. If it hangs because the output
pipe is closed it consumes no CPU.
What I can offer anyone who is having problems with pcgi_wrapper
on NT is a specially patched version that shoots itself after it has
been running for 1 hour (or any other delay if you recompile it). As
a bonus, when it does shoot itself it writes the the pcgi logfile a
message telling you on which line it hung. Unfortunately
(confession time) I don't seem to have saved a copy of the source
for the version that prints out the line number, just the binary. I do
have source though for the version that shoots itself, but doesn't tell
you how far it got. I have uploaded the relevant files to

[Zope] ZopeDA Event Notification, was: Interbase / Cacheing
Regarding the implementation of custom functionality in PostgreSQL, here's an "overview" from the PostgreSQL Programmer's Guide: "How Extensibility Works Postgres is extensible because its operation is catalog-driven. If you are familiar with standard relational systems, you know that they store information about databases, tables, columns, etc., in what are commonly known as system catalogs. (Some systems call this the data dictionary). The catalogs appear to the user as classes, like any other, but the DBMS stores its internal bookkeeping in them. One key difference between Postgres and standard relational systems is that Postgres stores much more information in its catalogs -- not only information about tables and columns, but also information about its types, functions, access methods, and so on. These classes can be modified by the user, and since Postgres bases its internal operation on these classes, this means that Postgres can be extended by users. By comparison, conventional database systems can only be extended by changing hardcoded procedures within the DBMS or by loading modules specially-written by the DBMS vendor. Postgres is also unlike most other data managers in that the server can incorporate user-written code into itself through dynamic loading. That is, the user can specify an object code file (e.g., a compiled .o file or shared library) that implements a new type or function and Postgres will load it as required. Code written in SQL are even more trivial to add to the server. This ability to modify its operation "on the fly" makes Postgres uniquely suited for rapid prototyping of new applications and storage structures." That last sentence tells much of the story. PostgreSQL was originally developed as a test bed for experiments in manipulating both tabular and non-tabular data. As such, significant effort has been devoted to providing an extensible toolkit, to meet the requirements of discoveries arising from an experimental environment. In PostgreSQL, the limit to flexibility seems to lie more with the user than the system!

Re: [Zope] The funny _.None,_ feature in DTML kind of question
I must admit that it was a bit too prompt reply by me:) - I guess that
_.None is used almost always - I do not know any uses for values other than
_.None, but the following exerpt from sources of Zope 2.1.6 can get some
hints:
DT_String.py: (afaik module from which all dtml methods inherit __call__ )
def __call__(self,client=None,mapping={},**kw):
'''\
Generate a document from a document template.
The document will be generated by inserting values into the
format string specified when the document template was
created. Values are inserted using standard python named
string formats.
The optional argument 'client' is used to specify a object
containing values to be looked up. Values will be looked up
using getattr, so inheritence of values is supported. Note
that names beginning with '_' will not be looked up from the
client.
The optional argument, 'mapping' is used to specify a mapping
object containing values to be inserted.
Values will be inserted from one of several sources. The
sources, in the order in which they are consulted, are:
o Keyword arguments,
o The 'client' argument,
o The 'mapping' argument,
o The keyword arguments provided when the object was
created, and
o The 'mapping' argument provided when the template was
created
'''
so client part provides some more indirection than simple "_" mapping, which
is, as Michel Pelletier wrote in the letter I quoted, "the current DTML
namespace"...
also in DTMLDocument.py:
def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw):
"""Render the document given a client object, REQUEST mapping,
Response, and key word arguments."""
kw['document_id'] =self.id
kw['document_title']=self.title
if hasattr(self, 'aq_explicit'): bself=self.aq_explicit
else: bself=self
if client is None:
# Called as subtemplate, so don't need error propigation!
r=apply(HTML.__call__, (self, bself, REQUEST), kw)
if RESPONSE is None: return r
return decapitate(r, RESPONSE)
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
if type(r) is not type(''): return r
if RESPONSE is None: return r
hh=RESPONSE.headers.has_key
if not (hh('content-type') or hh('Content-Type')):
if self.__dict__.has_key('content_type'):
c=self.content_type
else:
c, e=guess_content_type(self.__name__, r)
RESPONSE.setHeader('Content-Type', c)
return r
seems like client is supplied only when called over the http, not as a
method inside a method(???)

Hmm... what do you mean by method operatind on some object? I thought that
in dtml "methods" are kind of an object themselves... so e.g. they inherit
properties of their containers just because those attributes are in a
namespace. (the only exclusion here could be methods of ZClasses)

Maybe (I didn't look into the code - I am not a python/C wizard, especially
when it comes to python classes defined in C programs :) ) those client
settings are used in Zclasses? i.e. class as an object is passed in that
client argument to all methods of its instances... It is most likely what
could be called "methods operating on objects" in dtml

Re: [Zope] Interbase / Cacheing - A thought
Hannu, Does PostgresSQL allow you to have dynamic events? By this I mean can you do things like : PostEvent "Update_tblUsers_Record_" + new.RecordID; I believe that in Interbase the events are compiled into the trigger, not interpreted at Runtime so you can't have an Interbase event alert you to a change in a particular record, only that a change has occurred on a table. Coming from a RDBMS background myself I'd prefer to see RDBMS integration be tighter to Zope - properties etc being stored in the database where appropriate. For reasons of speed you don't want to have to go to the DB each time you want a property but having a data-aware object which knows when to update itself would solve this problem nicely. It should also help with load-balancing and failover where you could have a cluster of Zope instances all working on the same monster DB, all being kept in sync. via the event alerter mechanism.

So, the answer has SOMETHING to do with the #whatever= that trails at the end of the URL. When this is removed, all is well. Is this just a HREF anchor jump? The answer might possibly be for me to eliminate it from my python tree code, unless it serves some other purpose (not serving a purpose for me, these are small trees). So, am I wrong to think you can use anchors in a tag? I would assume so, but Netscape does render DIVs in a sort of bizzare way, so perhaps you cannot. In which case, this has nothing to do with zope, but more to do with Netscape. Well, that sucks. :) Anyway to work-around this within the code by modifying tree-s or e or c?

HomeSite is indeed a wonderful program! Very extensible, you can even teach it about DTML within reason. Unfortunately "Design View" uses an embedded Microsoft HTML editing control (cousin of FrontPage Express) that is NOT wonderful and not under Allaire/HomeSite's supervision. That's why they have options to "repair" your HTML after visiting Design View. :) They only put it in there so they could offer some sort of WYSIWYG as a selling point against other packages.

Re: [Zope] The funny _.None,_ feature in DTML kind of question
There is some more information at http://www.zope.org/Documentation/How-To/AdvancedDTML Look for the section "DTML Calling Arguments". Reading that left me a bit confused because here you say (and I have read elsewhere too) that method is passed client=_.None. I thought that the client should be the object on which the dtml method 'operates'. So how does the dmtl method access the attributes of the object it is called upon?

[Zope] Interbase / Cacheing - A thought
Had a thought that I wanted to share. Interbase has a feature known as "event alerts". In a trigger you can post "events" which are just fixed data strings e.g. "DataAdded" or "Insert_tblUsers". A client database connection can register to listen to these events. I don't know if any Zopeish Interbase access method supports this (ODBC doesn't to my knowledge) but it would be incredibly useful for synching cached database objects. Zope could hold a representation of the table data in cached objects for quick access. Each object could have one or more "event" methods which related to a database event. When the database adaptor received an event message from Interbase it could inform all objects with a matching event method (these methods would refresh their cached data with current values from the database). In this way database and Zope cache could be synced *without* having to poll the database at an interval. In all, a very efficient mechanism.

I use Zope in the old bobo fashion. I have a homegrown session management class that I use. When a session is idle for a long while, I ask the user for his password again before allowing him to continue. Generally, I then use the URL from the REQUEST object and RESPONSE.redirect() to send him where he was trying to go after he reenters his password (he never got there because I gave him a session timeout screen instead). This works well except in one case. If a user submits a form that uses POST to send it's data, I am not forwarding the posted data and so I get a Zope error that a parameter is missing. Is there a way for me to get the raw posted data and forward that too via the RESPONSE object? A seperate small side question. I thought that all the paremeters after the "?" in an URL or a submitted form (using GET) are put into the QUERY_STRING variable within the REQUEST object. I don't see this variable there at all.

[Zope] textindex problem
Hi I have my own zClass I catalog in "Catalog" my add-method does a reindex_object and everything works fine when I index the 2 properties "title" and "country" as Keyindex or FieldIndex. But when I index em as TextIndex, I cannot find em anymore. e.g. when my property country is "italy" and I search for "Italy" in Fieldindex I get the result, in TextIndex not Any ideas? TIA phidu
[Zope] Q: Link status/checking -
Kindest, I was wondering about a few points I havn't seen any references to. Are there any implementations in Zope that can verify the validity of an url? That is; 1) A link database is generated .. and should be maintained. 2) A process should be run at least once a week to check the validity of links in the database. 3) If the link is not "valid" .. it sets a tag in the db which says it's untrusted .. which again could show that in the link listed on the web through Zope. 4) .. and if it's untrusted for N runs .. it is removed. .. have anyone looked into that? .. and anyone made any conclusions as to how one can solve that? I am not that familiar with Python .. but I might be interested in generating such an engine.. based on Zope / mySql of some sorts. .. Perl support would really make me happy right now!

Aha, well, the GPL-vs-BSD-vs-MPL-vs...! :))) As PostgreSQL mailing list member you (like me) saw these debates many times. I don't think we need to continue the flame here :) There are people who loke BSD-style licensing, and there are GPL devotee. In this far-from-ideal world it is hard to say what is more free.

Easiest (most brutal?) fix I've found - hide Zope behind an Apache, and prohibit access to any URLs of the form .*/manage.* If you don't need to use basic auth to the Zope, then use a rewrite rule to strip out any Authentication headers in the requests.

AFAIK this is the only DA with GPL license. Both Zope and python have much freer licenses making GPL probably a poor choice if you "aims to replace the current ZPygresql DA".

[Zope] Linking to Mailing List Managers
Hi, With all the talk about Syndication I started to think about linking with mailing list managers. Ideally I'd like members of my portal site to be given a free email address @, bouncing all mail to that address to their real email address. In a roles-based membership scheme it would also be nice to be able to send email to @, so the email goes to all members with that role. Has anyone done anything like this, linking to an existing Mailing List Manager like Majordomo from Zope? I want to manage the whole thing through some Zope management pages. - Ian Sparks. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] KeyError since installing Squishdot 0.4.0
Since I installed Squishdot 0.4.0 (yesterday) on Zope 2.1.6 (under Red Hat
Linux) I've been getting KeyErrors when clicking on an article's topic
image, which uses an URL like this:
http://myserver/Zope/testsquish/search?subject=Squishdot&op=articles
In Squishdot 0.3.2, the errors didn't occur.
I applied the fixes mentioned by Michel Pelletier in his (Zope-dev] message
("The Mysterious Key Error and Unrelated Searc Result Bug"), and updated
the ZCatalog. This didn't fix the problem.
Here is the stack trace:
