Also, PHP has OOP 'capabilities' whatever that means - so maybe I can still use it like Python to a certain extent. Google is php object oriented and you'll get plenty of somewhat relevant hits. In terms of true OO languages (like python, ruby, java...), this may be a most relevant link: http://michaelkimsal.com/blog/php-is-not-object-oriented/ And, what he is pointing out may not be a problem for you, if mostly procedural with some object capabilities is suitable for your needs. If you are using python to build a zope product, the ZODB is used automagically, you don't have to do anything special. To access MySQL DBs you have to add an appropriate zope product to handle queries. A search on zope with mysql ...or vice versa returns mostly IMO embarrassingly old hits, many from old.zope.org and five to ten years old. So either the old info is still valid, or there is a lack of current information on using zope with mysql (though it is said that it is easy - where are non-stale howtos/tutorials for those who don't already know how?). Can you point me to a resource for Python and mySQL? I've bought 'Dive into Python' but it has no reference on how to use it with mySQL. If my current hosting provider supports Python and mySQL, can I make it work? They won't let me install anything on the server side though, so I can't use any modules that aren't there already. Look for info/howtos on Python's DB-API and the MySQLdb module. For example: http://pypi.python.org/pypi/MySQL-python/ http://sourceforge.net/projects/mysql-python/ http://zetcode.com/databases/mysqlpythontutorial/ http://www.devshed.com/c/a/Python/MySQL-Connectivity-With-Python/ ...though sounds like you can't add such modules on your current provider's server if not there already. Myself for a project of this complexity I would want much more control of my server options than it sounds like you have. A low-cost VPS (I use linode.com), or simply use localhost until I have my options sorted out. regards, John S. -- John Schinnerer - M.A., Whole Systems Design - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration j...@eco-living.net http://eco-living.net ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )

And how would you create (and update) objects in Python for: at least 500 tools as of now, and it is bound to grow in the future as newer tools are introduced. Existing tools will also have version updates. Each tool, on average, has at least 100 properties that define the tool. Some of them have as high as 1000 unique properties. How familiar are you with OOP? What I mean is, when I read your high-level description of what you want to do, I imagine objects interacting with other. In your car wash example I see that, for instance. Or any kind of work-flow, which is what this sounds like to me. A state machine. Each tool is an object; it knows what its properties and abilities and possible states are and can communicate them to other objects and can accept and act on communication from other objects. In that way the objects interact with one another to do whatever it is you build them to do. I'm thinking of your car wash metaphor. In a car wash there are a variety of elements (objects) that communicate with one another to move the car through and to wash it as it moves through. Simple example: * mechanism that pulls or pushes the car through * mechanism that sprays it with water and soap * mechanism that scrubs and wipes and rubs it * mechanism that sprays it with rinse water * drying mechanism(s) These all need to signal one another so they do the right thing at the right time. Spray (or scrub or blow hot air) only when the car is in the right place for each. If some tools can be built by adding to/extending other tools, that is an object-friendly situation, since enhancing an existing tool to make another that you need saves you having to create all tools from scratch. In the car wash, maybe the different sized scrubbers used are all made by bolting together two or more of the smallest size scrubber. Maybe in parallel, maybe in series, depends on what is needed. Maybe the same scrubber controller can have different size brushes attached to it. In short, an object - tool - is code and data that interacts with other tools (other entities of code and data). An upgrade to a tool would involve changing the code and/or data that constitutes the tool. If that introduces some new way of interacting that other tools need to also know, then you add that to those tools also. Adding more tools means coding them. If they can be based on existing tools, so much the easier (and more object-appropriate). So that's some high-level information about an object-oriented approach to what I think your project is about. Tthe flexibility you appear to need as the system grows may be problematic for an RDB. And, my bias is OO, so perhaps someone who thinks in RDB-space can describe at high level how this would look in an RDB implmentation. cheers, John S. -- John Schinnerer - M.A., Whole Systems Design - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration j...@eco-living.net http://eco-living.net ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] Safe way to abort or re-start stalled out ZODB pack?
Hello, This is for Zope 2.9.8-final, python 2.4.4, linux2 (debian) (installed by the Plone 2.5.5 installer if that matters, and using zeoserver) I have a ZODB pack operation started via the ZMI control panel that has failed to complete. It appears to be from a disk space issue (traceback below). The zope instance is still working fine on the pre-pack ZODB, and, there is a Data.fs.pack file sitting in ../zeocluster/server/var which hasn't been modified in the last ten hours. I need to know how to deal with this situation safely - how to abort and/or safely re-start the pack (the disk space issue has been dealt with). Some questions that have come to mind are: Is it safe to just restart zope? Will that clear the stalled pack operation automagically? Will I need to do something manually with the Data.fs.pack file? Any assistance appreciated...! thanks, John S.

Thanks Bakhtiar, That's what I was hoping, and I wanted some confirmation from those who've done it. I just did as you indicated - deleted Data.fs.pack, then ran the pack again.

[Zope] Character display issues upgrading 2.8.8 to 2.9.8
Aloha, I am in the process of moving from zope 2.8.8 to zope 2.9.8 (running on debian 4.0). I am transferring individual zope sites from 2.8.8 instance to 2.9.8 instance via export/import. So far everything is fine except... I have some content in StructuredDocument objects that includes text with some accented French characters, and some of the curly quotes (the 6--9 quotes) and real apostrophes and that sort of thing. They are not displaying correctly in the 2.9.8 zope - they show up as whatever symbol the browser uses to say oops, can't display this correctly. Both zopes are running on my dev system and I'm looking with all the same browsers so it seems it must be something to do with zope handling the characters (or not). The zope.conf settings for default-zpublisher-encoding are left at the default (iso-8859-15) in both instances, if that is relevant. I've never had any problem like this before, such as in previous upgrades of 2.7.x to 2.8.x. I don't even know where to look, aside from the zope.conf setting above which is the same in both cases. Any ideas why this is happening?

Re: [Zope] need advice on mass data processing
Aloha, Sounds like your data case/data model is better suited to a SQL database (Relational DB instead of Object DB). Zope works with MySQL, PostgreSQL etc. via ZSQLMethods. Look into using those, with your existing data going into a SQL DB (or maybe it is already?), if you want/need to access and manipulate the data from within zope applications. Then you also have the option of accessing that data via any app/platform that can talk to your SQL DB. I have a project I am working on where a portion of the data is very RDB-type data, while the rest is more zope/object content-management stuff. So the RDB-type data will be in a MySQL DB, and, accessible through the same zope-based platform that also provides the CMS for document/object management. Meanwhile if other stakeholders now or later want access to the RDB-type data they don't have to use zope, they can use whatever they want that will talk to MySQL. cheers, John S.

Re: [Zope] Isn't DTML more like what other frameworks do?
Aloha, Mark, Jonathan (Integic) wrote: What does matter is that DTML is very similar to RHTML (as in Ruby On Rails), ASP, etc. ZPT requires a new way of thinking. I would much rather convert RHTML to or from DTML than to or from ZPT. So I don't really get the benefit of using ZPT. The fact that no one outside of Zope seems to have created a ZPT-like solution suggests to me that ZPT, as I said, solves a problem which doesn't exist. As mentioned other frameworks use TAL/METAL (the basis for ZPT; bear in mind ZPT is a zope-specific use of TAL and METAL) - I have worked with Roundup a bit and it was a joy to see that it used TAL for template language. One major factor nobody has mentioned yet is that TAL/METAL offers much better ability to separate logic, presentation and content. By their very nature HTML-munging template markups violate this well-known (if not well-respected ;-) design principle. The WYSIWYG editor thing is merely a side benefit of markup that is both XML compliant and cleanly separates logic, presentation and content. I suspect that nobody else created TAL because it is easier to go with what one is familiar/comfortable with - HTML-munging - than to break new ground, even when the new ground is better in both design and practice. Sure DTML is more like PHP and ASP and Ruby/Rails' HTML munge and Alfresco's HTML munge and so on (whatever they're called).

Re: [Zope] Zope 2.9 Product Refreshing
Since I never knew the refresh tab was a fragile hack, it always worked fine for me... :-) Are you saying that a really good solution for this is in the hands of python developers, not zope developers? In that case it seems far off, if ever, since zope is only one of many many applications using python. I would settle for another fragile hack that works, I guess. The volume of posts so far would seem to indicate that it's not a trivial topic... John S. Chris McDonough wrote: The real effort towards making a better refresh should likely be spent at the level of the Python interpreter. The dynamic nature of Python is the thing that allows for a refresh in the first place, but the implementation of Python object references limits its usefulness. The implementation of reload could be vastly improved by changing Python internally to allow for a sort of mark-and-sweep reload that could traverse an object graph full of references between an object and the modules that it is declared in. Anything else will likely be too fragile to work in all cases.

Comment on Peter's suggestion: I am no expert on these things, but it is
my understanding that for MySQL LAST_INSERT_ID() fetches the last
autoincrement value made by the current insert, so the outcome is not
affected by virtually simultaneous requests. And I don't think MySQL
accepts a value for the autoincrement key. I am a bit surprised that the
code you quote is reliable - surely there is a possibility of an insert
after calling GetNextID and before calling SQLInsert in the python code?
Comment on Tino's suggestion: I think that LAST_INSERT_ID() is MySQL
specific and I guess CURRVAL() is Postgres specific. But the principle
is the same: calling within the same Z SQL Method ought to be safe.
Anyway, I hope John has had is question answered.

[Zope] Improved Zope Org Proposal
Aloha, ... I start to understand: You want to have a narrow, a focused site because you fear that a bigger one cannot be managed. In such a case, I would say: start with the small solution and maybe get bigger later. This is a basic principle of design that works (as opposed to design that fails to work). Start small and work the edges outwards. The work edges outwards that works is often modular in nature (perhaps a.k.a. 'micro-sites'). That doesn't mean it can't look-and-feel like one big site as access point. Biting off more than one (person, organization, whatever) can chew usually results in choking... So I actually see a lot of agreement in what may appear to be argument. Also: I agree that despite the wonders of zope, the zope.org site is not as stunning a place to refer people to as it could be. For the most general public face of the site, I support the idea of a clear and simple brochure-like approach. A couple major open source project/product sites that I am excited about referring people to: http://rubyonrails.org http://www.mozilla.com ...and to some extent http://www.openoffice.org ...although IMO the OO site is not quite as clear and well-designed as the other two...better than zope.org though. Also bearing in mind that the Ruby On Rails site is for a development platform while Mozilla and OO are end-user app sites - somwhat different audiences. cheers, John S. -- John Schinnerer - MA, Whole Systems Design -- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration [EMAIL PROTECTED] http://eco-living.net ___ 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 )

On the other hand, I do sometimes find just what I need somewhere in all of what's there...and it's not usually easy. And, sometimes, it's somewhere in all that bit-rot that will no longer be supported...so I guess there will be less cruft and, hopefully, not too much less useful information in the new site? What I would really appreciate on a new zope.org site would be an improved search functionality. Something that lets me filter out all but certain types of objects would be great. If I'm searching for a product, I only want to see hits on relevant product objects or directly related objects that will clearly point me to a product (like a product review, if there is to be such a thing)...likewise for HowTos, etc. etcinstead of as now where I get back all kinds of objects that happen to be hit by my search string even when most of them are irrelevant types of objects. And thanks to everyone working on making a new site happen! cheers, John S. -- John Schinnerer - MA, Whole Systems Design -- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration [EMAIL PROTECTED] http://eco-living.net ___ 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 )
[Zope] When is an empty list not an empty list?
Aloha,
I have a python script, getCatalogItems(), which returns a (possibly
empty) list resulting from a catalog query. The lone parameter is the
sort index; the rest of the query is taken from the request. Anyhow...
If nothing was found, I don't want to display an empty table of results.
When I do this query and then check for empty list to see if the query
returned any items:
div tal:define=items python:container.getCatalogItems('id')
table tal:condition=python: items!=[]
...
...it doesn not work, that is, the (empty) table displays when items is
in fact an empty list.
If I do this instead:
div tal:define=items python:container.getCatalogItems('id')
table tal:condition=python: len(items)0
...
...then the condition works, no empty table is displayed if the list is
empty.
Why does the former not work and the latter does?
I need to understand the difference in the python expressions...makes no
sense to me at present that they don't work the same.
thanks for any help,
John S.

[Zope] questions on multilingual sites
Aloha, I'm currently doing a custom small business site that might also want to be in French further down the road. I've never used the internationalization aspects of zope yet...so a few basic questions: Can additional language support be added in later, or is it necessary to build it all in from the start (even if not used yet)? What are the basic docs/tutorials/howtos I should look at to start understanding how zope language support works and how to best apply/use it? thanks for any assistance, John S. -- John Schinnerer - MA, Whole Systems Design -- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration [EMAIL PROTECTED] http://eco-living.net ___ 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] When is an empty list not an empty list?
Aloha,
Thanks, I understand...though it's a bit annoying that it looks and acts
just like a list but isn't...
Just using items does work. I figured it would work for True when not
empty...I wasn't so sure what it would return when empty, as sometimes
the test seems to be on 'exists' rather than 'empty', depending on the
type of object.
At least I grok this particular case now, thanks again...
cheers,
John S.

Well, thats because getCatalogItens() does not return a list. It might
look and work like it, but it isnt the same class. Python defines
comparisions between different classes as always false.
Easier in your case would be just:
tal:condition=items
non empty python objects are usually logically True.

Tino

[Zope] How to set selected items in multi-select list from lines property
Aloha, I have an add form where a user can add an object. In one part of the form, the user selects zero or more options from a multiple select list. The selected options populate a lines property of the object when the object is added. I also have an edit form where the user can later edit these same objects they've created. They can use the same multiple select list to change the selected options. Of course the previously selected options (in the lines property) need to be displayed as such when they first visit the edit form. So... I need to know how to display the multiple-select list in the edit form so that the options currently in the lines property are set as selected. I suspect there is some very slick way to do this, maybe with TAL alone...? So far I am only coming up with what seem to be cumbersome solutions that have unecessary overhead (comparing a list option with every element in lines property via python script to see if it should be set selected, and repeating for every list option)...is there a better way? Any help appreciated. thanks, John S. -- John Schinnerer - MA, Whole Systems Design -- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration [EMAIL PROTECTED] http://eco-living.net ___ 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 )

[Zope] Looking for current shopping cart product
Aloha, I am wondering if there is any current and stable shopping cart products for zope (2.7.5 is my current live version). I have a custom merchandise product for a client's business site. Retail sales are already handled via their PayPal merchant account. The retail items only need the appropriate PayPal button/form code and PayPal handles the rest. However the client also does wholesale, but not via PayPal, and wants a wholesale cart into which a wholesale buyer can put items and quantities to submit for review, final pricing, and shipping costs. I have just looked on zope.org and under products - commerce I don't find anything that looks current. I searched zope.org also and didn't find anything. I googled around a bit for zope shopping cart product and simliar and still didn't find anything that looked viable. Is there anything out there?

Re: [Zope] Re: Using ReStructuredText instead of StructuredDocument inside ZPT
Aloha, Thanks for pointing me to that document, that's what I needed. The example for TAL integration works just fine (with the typo fixed :-), and also renders only the actual content, without adding the whole XHTML document structure around it. cheers, John S. In your Zope distribution files look at 'doc/RESTRUCTUREDSTEXT.txt' (or 'Zope/doc/RESTRUCTUREDSTEXT.txt' with Zope2.9). It has examples of how to use ReST with different solutions. (There is a typo: 'restructured_test' should read 'restructured_text' ) Btw, the ZReST objects method 'source_txt' gets you the source text of the reST document. E.g. this should work in your example: p tal:define=rest_txt python:container.client_content.some_STX_object.source_txt() tal:replace=structure python: modules['Products.PythonScripts.standard'].restructured_text(rest_txt) / Hth, Michael -- http://zope.org/Members/d2m http://planetzope.org ___ 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 ) __ Do You Yahoo!?

[Zope] Using ReStructuredText instead of StructuredDocument inside ZPT
Hello, I have been using the Structured Document (SD) product with page templates (to provide some content sections that a client can edit using structured text). Now I would like to use ReStructuredText Document (RSTD) instead of SD. I have been using code like this in a page template to render the content of a SD within the page template: ... div metal:fill-slot=pagebody p tal:content=structure container/client_content/vision_statement Vision Statement /p /div !-- end of page body slot -- ... ...where vision_statement is a SD object. I expected that this would work the same if vision_statement were a RSTD object...however it does not. What displays is only the unrendered, plain text content of the RSTD. Can I use a RSTD object in the same way I have been using a SD? If so, how do I get it to render? This is on zope 2.7.5 with the ZReST that comes built in.

[Zope] Backing out the Zope Hotfix 2005-10-09 that broke my zope 2.7.5
Aloha, FWIW here's what I found while backing out the hotfix on my zope 2.7.5: The hotfix-installed files are set to an owner, group and perms that do not work with an existing install (zope fails to start up completely/correctly). I don't know if there are other problems also, but that was the relevant issue for me. More importantly, and more annoyingly for trying to back out, the owner, group and perms for the Products folder is altered to the same dysfunctional settings! I use debian, so I simply tried to reinstall the zope2.7 debian package to get the pre-hotfix files back. First I got some explicit errors on the hotfix-installed files that pointed me to the owner/group/perms problems with those. Then the debian package *appeared* to install, but zope still failed to actually start once installed and configured. It took me a while to notice that the owner/group/perms on the Products folder itself had been changed to the same settings, blocking correct/complete reinstall of the original files. Unfortunately the package install didn't raise any errors on this. Once I fixed the messed-up perms on the Products folder and did the install again, all was well. I put this info on the hotfix alert comments also.

FYI anyone upgrading to the recent Debian 3.1 release (sarge), the default in the config file in the zope package (2.7.5 final) in sarge has cgi-maxlen set quite low, 1 if I recall correctly, to block potential DOS attacks according to the comment on the setting (Debian is perhaps a bit paranoid in this case...).

Re: [Zope] Images too (StructuredDocument size limit reduced after 2.5.1 to 2.7.5 upgrade)
Aloha, OK, it's not just StructuredDocument objects, Image objects have the same problem, anything over about ~5-8K gets the same error message. Probably everything will, those are just the ones that have emerged first for me... Does anyone know what could be causing this? If it's some new configuration option(s) for 'content length' in 2.7.5, where the heck do I find and tweak them? I don't see anything in the ZMI that would affect this, don't know where else to look. thanks, John S. To recap, my server was upgraded from zope 2.5.1 to 2.7.5 and now StructuredDocument objects in a product I have built have a rather small limit (about 4-6K) on how much content can be put into them. The content is being put into them from content in a web form text area using a call like self.some-structured-document-object.manage_edit(REQUEST.stx-content, 'Name of Content') Nothing in the product was touched/changed, just the zope upgrade. The error message now returned in the browser window when I try and update a structured document with more than ~4-6K of content via web form is this: -- Site Error An error was encountered while publishing this resource.

That was what I needed, the parameter name...my sysadmin set it low for security reasons, not realizing it would impact my content editing products, he will bump it up and hopefully that will fix this. thanks, John S. __ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/ ___ 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 )
[Zope] StructuredDocument size limit reduced after 2.5.1 to 2.7.5 upgrade
Aloha, did you use POST or GET? If yoou use GET, use POST. If you use POST, then I dont know. Using POST, and I don't know either... Anyone else have any ideas? To recap, my server was upgraded from zope 2.5.1 to 2.7.5 and now StructuredDocument objects in a product I have built have a rather small limit (about 4-6K) on how much content can be put into them. The content is being put into them from content in a web form text area using a call like self.some-structured-document-object.manage_edit(REQUEST.stx-content, 'Name of Content') Nothing in the product was touched/changed, just the zope upgrade. The error message now returned in the browser window when I try and update a structured document with more than ~4-6K of content via web form is this: -- Site Error An error was encountered while publishing this resource. Error Type: ValueError Error Value: Maximum content length exceeded Troubleshooting Suggestions * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the error log. If the error persists please contact the site maintainer. Thank you for your patience. -- This error is *not* showing up in the error log viewable from the root of the zope instance. thanks, John S. __ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/ ___ 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] Re: StructuredDocument size reduced after 2.5.1 to 2.7.5 upgrade
Aloha, Some Zope version may have introduced a few new configuration options to control the size of uploaded objects (I see them in Zope 2.8.1 after I upgraded from Zope 2.7.1) -- maybe some of them are responsible... Where are they located? I don't see anything like that in the ZMI for 2.7.5. Are they in config files (which ones?), or...? maybe form trasport method too, see POST vs. GET. Form transport method is the same as before the upgrade from 2.5.1 to 2.7.5 - I changed nothing in my products or other code, only zope was upgraded. Did something about form transport method that would affect programmatic file upload size change between these two zope versions ? thanks, John S. __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [Zope] Re: upgrade 2.5.1 to 2.7.5 causes error in product code
Aloha,
python:here.sponsors[0] != ''
if the tuple is empty, whereas 2.5.1/2.1.3 must have been returning
some equivalent of boolean 'false' when the tuple was empty.
No. Python 2.1.3 would have blown up the same way.
Must have been Zope 2.5.1 somehow turning the python blowup into
equivalent of boolean 'false' then, or my clearly less than exemplary
code would have also failed under 2.5.1, as it does under 2.7.5.
Now I do this
python: (here.sponsors) and (here.sponsors[0] != '')
and it works again.
The second condition may be redundant now I suppose...?
No it is not redundant. A value ('',) would still be True as far as
Python is concerned and would pass the first condition.
Right, thanks!

And how to fix it, of course... :-? Sorry, but I cannot reproduce this problem with Zope 2.7.7 and large amounts of text in a StructuredDocument... can you send me a .zexp-Export of a StructeredDocument created with 2.5.1 which shows the behavior in 2.7.x? Maybe I'll can reproduce it and find the problem, but I don't think that it is related to StructuredDocument, because nearly all code is acquired from DTML-Document... For any StructuredDocument object I have, it breaks at approximately 4490 chars (seems to vary by a few chars - maybe due to how many line breaks...?). Less works OK; more returns the above error. My sysadmin did some serious digging and says the error message I get appears in /usr/lib/python2.3/cgi.py, lines # 142,272, and 511 he didn't find anything in the Zope code base that has this message. So may be a python thing...? Also says it looks like maxlen is getting mangled somehow (though the default is unlimited?). Attached is a zexp of the StructuredDocument object I just used to get the estimate of where it breaks. thanks, John S.

[Zope] StructuredDocument size reduced after 2.5.1 to 2.7.5 upgrade
Hello again, I am using StructuredDocument objects in the custom products I am migrating to 2.7.5 from 2.5.1. In 2.7.5 I am now getting an error Value Error Maximum content length exceeded when attempting to save changes (edits) of StructuredDocument objects with large amounts of content - even when there was no problem with the same large amount of content in 2.5.1. This error under 2.7.5 happens if a migrated object already has more than a certain amount of content in it when I do a TTW edit/update of the object using e.g. self.manage_changeProperties(REQUEST) It also happens at some point when I start adding increasing amounts of text into a StructuredDocument object that initially has small amounts of content (small meaning not enough to trigger this error under 2.7.5). I don't know exactly how much is too much. I do know that it is not very much at all, and certainly far less than the DTML document basis for a StructuredDocument can hold. It is also far less than what my StructuredDocument objects *already hold* under 2.5.1. Anyone have any idea why I'm getting this size-related error with StructuredDocument only after migrating to 2.7.5? And how to fix it, of course... :-? thanks, John S. __ Do You Yahoo!?

Re: [Zope] Re: upgrade 2.5.1 to 2.7.5 causes error in product code
Hello,
Thanks Tres, looks like zope 2.7.5/python 2.3.5 is triggering a genuine
full-blown error on my code
python:here.sponsors[0] != ''
if the tuple is empty, whereas 2.5.1/2.1.3 must have been returning
some equivalent of boolean 'false' when the tuple was empty.
Now I do this
python: (here.sponsors) and (here.sponsors[0] != '')
and it works again.
The second condition may be redundant now I suppose...?
thanks,

print here.sponsors
If the output is '()', then your sponsors attribute is an empty
