[Win XP] Installation problems
by Benmania Guin 29 Aug '05

29 Aug '05

Hi guys, I have some troubles to install "Zope" on my "Windows XP Home Edition" operating system. The installation procedure went on without any problems but whenever I tried to start the Zope server, either "in Console" or "as an instance", the server would not run. There was simply a window blinking up for a couple of milliseconds (so that I was not able to read the message) - and that was it - but no process was running. Is there any specific problem, e.g. caused by the operating system ("WIN XP HOME EDITION"), known (the registry, for instance) - or do you have any idea of the possible problem? I hope the prob is not too trivial to be answered. Thanks a lot for helping me (I am really frustrated 'cause I've been searching "the whole net" for advice that hints on a possible solution but I could not find any...).

File objects with illegal characters
by Peter Bengtsson 29 Aug '05

29 Aug '05

What is the best way to deal with file uploads with illegal characters? I have no problem stripping the filenames such that "_Peter[1].doc" becomes "Peter1.doc" before it's manage_addFile'ed. But suppose I want to maintain the exact filename as it was on the harddrive, how do you deal with that? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

Weird ZPT/Python mail problem
by James O'Keefe 29 Aug '05

29 Aug '05

Hi all, At work, I am testing our software that sends a postback via http to a test server on a periodic basis. I wrote the test server on our plone system. I have a page template that calls a python script. The python script gets all of the parameters and writes out their value to printed and then mails it off to a list of email addresses. Pretty simple system. When I the software I am testing calls this page (via an http post) I get the email message, but none of the parameters or their values are included in the email. I have another test server, this time written as a servlet running on Tomcat, that successfully logs the parameters and their values when called by the software. Now you might think that the problem is with the Zope based server, but I am able to successfully call the page via: o a form I setup in the same directory as the page template; o the above form on a different computer; o the unix wget utility on the server making the http post. Prior to this, I noticed that the message never got sent unless I was logged in and using the form on the test server. I fixed this by changing the MailHost's security parameter to enable "Use mailhost services" for all users. I looked over the other possible security permissions, but none jumped out at me that they might be a problem. Any suggestions would be most helpful. Thanks! Jamie Here are the relevant ZPTs/scripts: notify ZPT <h1 tal:replace="structure here/standard_html_header">Header</h1> <p tal:replace="structure python:here.notify_py()" /> <h1 tal:replace="structure here/standard_html_footer">Footer</h1> notify_py Python Script # Import a standard function, and get the HTML request and response objects. from Products.PythonScripts.standard import html_quote request = container.REQUEST RESPONSE = request.RESPONSE d = request.form.items() # Return a string identifying this script. print "<p>This is the", script.meta_type, '"%s"' % script.getId(), if script.title: print "(%s)" % html_quote(script.title), print "in", container.absolute_url() print "</p>" # Log what we received print "<p>" for arg in d: key = arg[0] value = arg[1] print key, ": ", value, "<br />" print "</p>" # send email # if that fails, then tell user to email us that they got an error try: mto = "someuser(a)somehost.com" mfrom = "someuser(a)somehost.com" subject = "notification message" body = printed context.MailHost.simple_send(mto, mfrom, subject, body) return printed except Exception: errorText = '<h1>Ooooppps!</h1><p>There was an error submitting your information to our database and our backup logging method. Please email the <a href="mailto:someuser@somehost.com">QA Dude</a> that you got an error so that we can track it down and fix it.</p><p>Thanks!</p>' print errorText return printed

I don't know how many parameters will be passed to the script by the form. I also don't know their names. I allready tried various things and did some research in the docs and lists but can't figure it out. I thougth of stuffing all the values in one list with the :records option but couldn't it right. I tried : <td><input type="text" name="item" value="" tal:attributes="name addr.item:records; value python:context.Templates.AddressTemplate.getProperty(item)"> </td> but this also doesn't work.

Zope3 i18n
by Pascal Peregrina 29 Aug '05

29 Aug '05

Hi, I am starting to have a look at Zope3 (I am a Zope 2 product developper). In Zope2, I currently use MessageCatalogs/Localizer/TranslationService for i18n. Where can I find documentation about the corresponding functionality in Zope3 (which appears to be i18n enabled) ? I would be intersted in particular about i18n tags in TAL. Thanks.

[ANN] iungo released to the wild...
by Maik Jablonski 29 Aug '05

29 Aug '05

Hi to all, today I decided to release iungo to the world-wild-world... iungo was already announced at the German Zope User Group (DZUG) some weeks ago, but today I started and finished translating most of the docs to english for a broader audience. The tutorial is still missing, but I'll do this in the next days too. What is iungo? -------------- Based on the web-application-server Zope iungo provides a solid system to build up object-oriented web-databases, easy-to-use-wikis, content-, document- and knowledge-management-systems. iungo targets users and developers, who trust in the "Keep it simple"-philosophy and want to maintain control over their work. iungo tries to connect people with information. Features? --------- - Strict separation of content and application: your content can be moved between different zope-instances and iungo-versions without the fear of breaking anything. - Folderish-Content: In the web all "entities" are links, not folders, documents or files... no more headaches for users what content-type to use... in the default iungo-install there's only one for all...;) - Placeless-Content: All objects have a unique id (autogenerated per default) and can be moved around within the repository without breaking any links between objects. - KISS (Keep it simple stupid): It's easy to develop a custom layout with a basic knowledge of DTML or ZPT. - Expandable: Create new content-types for webdatabases with some clicks in the ZMI. Where can I find more info about iungo? --------------------------------------- http://www.iungo.org/ If you have questions, feel free to ask me: maik.jablonski(a)uni-bielefeld.de Keep zoped, Maik

28 Aug '05

Hi, I'm fairly new to zope, trying to modify the file-library example to upload files, I've removed all the tests for file size, but still getting error on file size... 1. Where is the list of error messages and their meanings (error message reference)? 2. Is there a max file upload size set in a config file/screen? thanks in advance. mike.

Zope 3.1.0 RC 2 released!
by Stephan Richter 28 Aug '05

28 Aug '05

The Zope 3 development team is proud to announce Zope 3.1.0 candidate 2. Zope 3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. It is in our opinion that Zope 3.1 is more than ready for production use, which is why we decided to drop the 'X' for experimental from the name. We will also continue to work on making the transition between Zope 2 and Zope 3 as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in the form of Five. Now that we have a release that we would like to declare stable next week, we are looking for translators, who translate Zope 3 into their favorite language! We are utilizing the Rosetta system from Ubuntu for managing those translations. If you are not familiar with Rosetta, please send us a mail to zope3-dev(a)zope.org and we get you set up. Downloads http://zope.org/Products/Zope3/ Installation instructions for both Windows and Un*x/Linux are now available in the top level 'README.txt' file of the distribution. The binary installer is recommended for Windows. Zope 3.1 requires Python 2.3.5 or 2.4.1 to run. You must also have zlib installed on your system. Changes Since 3.1.0c1 - Removed an untested missfeature that can cause infinite loops in principalfolder's Principal class. - Switch to METAL 1.1, which solved a serious bug. - Grant view cleaned up. - Add missing id attribute to select widget. - pytz has been updated. - Some code optimization in the HTTP factory of the publisher and ftesting framework. - Multiple headers having the same name are correctly handled now. - Now SQL operation parameters will be properly encoded before executing. - More carefully handle case when SQL parameters is a tuple or a list of a tuples. - All request factories can now be configured. - Script and Installation documentation improvements. - Fixed several bugs in API doc. Also provided some flexibility with the UI. - Fix to source widget hasInput and associated changes - Updated Build System. - Fix I18n bugs. Updated Russian and German translations. Most Important Changes Since 3.0 - New Pluggable Authentication Utility (PAU), which is similar in philosophy to the Zope 2 PAS. The following features are available in the in the basic PAU facility: + Credentials Plugins: Basic HTTP Auth, Session + Authenticator Plugins: Principal Folder, Group Folder For a detailed description of the pluggable authentication utility, see 'zope/app/authentication/README.txt'. - Major simplifications to the component architecture: + Removal of the concept of a service. All outstanding services were converted to utilities: Error Reporting, FSSync, Authentication. + Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar. + Local registrations can now only have two states: active and inactive. This simplified the code so much, that 'zope.app.utility', 'zope.app.registration' and 'zope.app.site' were all merged into 'zope.app.component'. + Implemented menus as utilities. The API also supports sub-menus now. + Implemented views as adapters. Skins and layers are now simply interfaces that the request provides. - Added an integer-id facility for assigning integer identifiers to objects. - Added basic catalog and index frameworks. - Added "sources", which are like vocabularies except that they support very large collections of values that must be searched, rather than browsed. - Created a new granting UI that allows advanced searching of principal sources. - Implemented a generic user preferences systsem that was designed to be easily used in TALES expressions and via Python code. Preferences can be edited via 'http://localhost:8080/++preferences++/'. A demo of the preferences can be found at:: http://svn.zope.org/Zope3/trunk/src/zope/app/demo/skinpref/ - ZCML now supports conditional directives using the 'zcml:condition' attribute. The condition is of the form "verb argument". Two verbs, 'have feature' and 'installed module' are currently implemented. Features can be declared via the 'meta:provides' directive. - Improved API doctool: Code Browser now shows interfaces, text files and ZCML files; the new Book Module compiles all available doctext files into an organized book; the new Type Module lets you browser all interface types and discover interfaces that provide types; views are shown in the interface details screen; views and adapters are categorized into specific, extended and generic; user preferences allow you to customize certain views; 3rd party modules can now be added to the Code Browser. - Improved I18n-based number and datetime formatting by integrating 'pytz' for timezone support, implementing all missing format characters, and reinterpreting the ICU documentation to correctly parse patterns. - Added '++debug++' traversal adapter that allows you to turn on debugging flags in 'request.debug'. Currently the following flags are defined: source, tal, errors. - Improved logout support. - Added the HTTP request recorder, which lets you inspect raw HTTP requests and responses. It can be used to create functional doctests without requiring third-party tools such as TCPWatch. - Developed a generic 'browser:form' directive. It is pretty much the same as the 'browser:editform' directive, except that the data is not stored on some context or adapted context but sent as a dictionary to special method (by default). For a complete list of changes see the 'CHANGES.txt' file.
