zope2.7b1 does not start on winXP
by Elena Schulz 22 Aug '03

22 Aug '03

Hi, I can't get zope2.7b1 starting on winxp after installing the binary for running *not* as a service (the other option i did't try). I have installed it parallel to a zope2.6., Plone and Active Python 2.2. but that shouldn't be a problem? Any hints what could be wrong, fixed, configured etc. There are no error messages, just the cmd-window closes directly after starting runzope.bat. -- Thanx Elena

Hey Bart, Here are some more recent benchmarks: http://zopeedge.com/benchmarks You can see that an 867 Mhz PIII box with 128 MB of Ram was still pulling 88 requests per second (over 7,500,000 requests a day) on a dynamic page.

SUMMARY: strange unicode behaviour, unicode and ZCTextIndex
by Giuseppe Bonelli 10 Aug '03

10 Aug '03

I post this for the mail archives. Everything is pretty obvious, but I think it can save some headaches to others. ABSTRACT: I hit some unicode related problems when testing a unicode aware, multilingual xml repository Zope product. What follows is what I learned and what is working (which now is, luckily enough, almost everything). T The following has been tested on Zope 2.6.1/Py2.1.3 installed from binaries on win32 (but it should be platform independent). THE QUICK ROUTE 1. have a sys.setdefaultconfig in sitecustomize.py 2. use RESPONSE.setHeader('content-type','text/html;charset=<dtml-var your_preferred_encoding>')"> in _both_ your user _and_ ZMI pages 3. let python/Zope do the encoding/decoding for you (i.e. don't use .encode(your_preferred_encoding), unless you know what you are doing) 4. You don't have to start Zope with any locale to have ZCTextIndex work nicely with unicode content. FOR THE BRAVE CURIOUSES **1. sys.setdefaultconfig** <quote from="Toby Dickenson"> <original msg from="Giuseppe Bonelli"> I have utf-8 as sys.defaultencoding and I do not load any locale when starting Zope. </original mg> That is old advice that predates Zope 2.6. It was never a particularly good idea, because it affects all of pythons internals. You only need to encode your unicode as utf-8 (or other encoding) before sending it over the network, and ZPublisher is capable of doing that itself if you tell it the encoding in the header. </quote> That's true, but you will definitely need to set a default encoding if you are going to use python code. If not set, the default encoding is ascii and you will get the usual "encode error, ordinal not in range (128)" error when doing as a simple thing as Print string_with_some_special_chars_inside. To set a default encoding: create (or edit) a sitecustomize.py file in your zope_install_dir\bin\lib (or in the phyton used by zope) and use: import sys sys.setdefaultencoding(my_encoding) ***2. content-type This is trivial for your user interface pages: just add <dtml-call "RESPONSE.setHeader('content-type','text/html;charset=<dtml-var your_preferred_encoding>')"> in the <head/> of your standard_html_header. I found it non trivial for the ZMI pages, as I discovered that the default encoding in the ZMI pages is governed by a variable named management_page_charset, which has a default of iso-8859-1 (and I was using utf-8 for automatically generated titles properties ...). If you need to change this default you can use a property named management_page_charset in the top folder of your app. This works, but is not future proof (see manage_page_header source under lib/python/app/dtml for details on this). The best option would probably be to use a <dtml-call "REQUEST.set('management_page_charset','your_preferred-encoding')">. Why REQUEST.set and not just use a meta "http_equiv=content-type" ? <quote from="Tino Wildenhain"> <original msg from="Dieter Maurer"> I never understood why the meta "http_equiv=content-type" did not work, just recognized that it did not work reliably. </original> This influencing of HTTP-headers via HTML is very problematic because 1) there are often real HTTP-headers, there seems to be no definition which takes precedence over the other 2) Downstream proxys cannot read HTML embedded HTTP-header, but base their caching strategy on the real headers. This will sometimes lead to confusing experiences In general, if you have control over the real HTTP headers, you should use it and not include something like that in HTML. With zope we are in the happy position to have control as opposite to a "web-business-card" where you just dump a couple of HTML files onto a hosters server. A patched ZPT could transport information from HTML meta to REQUEST... interesting idea. </quote> ***3. ZCTextIndex My original ZCTextIndexes problems were due to a combination of above and to leftover words from indexes removed during testing (Heisenberg Uncertainty Principle applied to s/w at play here: during testing, if you change something the testing itself is influencing the system). If you still experience problems, delete the lexicon, recreate it and reindex. If problems persist, double check that you are not mixing unicode/non unicode content in your indexes (if you followed quick route #3 above, this should not be the case). (H)ACKNOWLEDGMENTS Thanks to all who helped (Dieter, Tino, Toby, Hannu, Hugo). END NOTE As always, a debugging session is not fun, but you end up with some new python/Zope insights. __peppo

Hi All, Got an issue with a search feature that was configured by a client of mine, when they choose to search using a keyword, they get this error: Site Error An error was encountered while publishing this resource. _mysql_exceptions.NotSupportedError Sorry, a site error occurred.

cannot add STX Documents
by Marcus Bergmann 07 Aug '03

07 Aug '03

Hello, I run a new 2.6.1 version and imported the user directories and the STX Document product from an old 2.5.0 version (via export/import not copying the data.fs). The existing STX and RSTX Documents are ok. I can view and edit them. But I can't add new STX or RSTX Documents. Has anyone an idea what I'm doing wrong? This is the traceback: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module OFS.DTMLMethod, line 126, in __call__ Module DocumentTemplate.DT_String, line 474, in __call__ Module DocumentTemplate.DT_With, line 61, in render Module DocumentTemplate.DT_Util, line 201, in eval - __traceback_info__: REQUEST Module <string>, line 2, in f NameError: global name 'STX_Document' is not defined Thanks, Marcus!

Automatic authenticating users in Zope behind IIS
by Carsten Gehling 02 Aug '03

02 Aug '03

I am going to use Zope to form an intranet for a TV station. The situation is, that all users (using Windows 2000 workstation and Internet Explorer 5.5) are logging on to an Active Directory Server. The intranet is to be implemented with Zope running behind IIS 5.0 (or the newer one if it can solve the problem). IIS and IE has a special function: If the directory security is set to ONLY "NT Challenge/response" AND the intranet URL is set in IE to the security level "Local Intranet", the user need not make a separate authentication to enter the intranet. Instead IE sends to IIS the user details previously entered when loggin onto the Active Directory Server. IIS then validates the user against the same AD (and also checks with user permissions on the directory/website). If the user is authenticated and have permissions to execute scripts, the script in question is called with an extra server variable called "LOGON_USER". This work with both ASP and eg. PHP. I would like this to work with Zope as well, so that Zope does not display an authentication dialog box. I see two ways to do this, however I do not know if it would work, or even how: 1) Zope is run behind IIS with PCGI. All users with access to the intranet must be added to the permissions for the intranet's root rolder. Zope user folders are made with the special LDAPUserFolder 2) Zope is run as a standalone server. Zope must simulate IIS's challenge/response system. Zope user folders are made with the special LDAPUserFolder Have anyone tried this before? I'm still at the level of getting PCGI to work properly. ;-) Any help is much appreciated. - Carsten

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I am trying to get my head arround on how to build a registration form, that has a one-to-many relationship.
