Zope 3.1.0 RC 3 released!
by Stephan Richter 16 Sep '05

16 Sep '05

The Zope 3 development team is proud to announce Zope 3.1.0 candidate 3. 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 3.1.0c2 - Fixed several bugs that were considered critical. * Ported Stuart Bishop's work in ``pytz`` and ``zope.i18n`` to address broken and misleading timezone code (i.e., one issue was broken and another was misleading). * Fixed apidoc to handle extended paths, so that zope packages could be installed in software instances without apidoc losing knowledge of the core zope code. * Added custom ``executemany()`` method for cursors created through GadflyAdapter. See http://www.zope.org/Collectors/Zope3-dev/445 for discussion. - Updated ZODB to 3.5.1b2. 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.

Installing Python Modules Under Zope On Windows
by tom＠tompurl.com 16 Sep '05

16 Sep '05

I have a hardware constraint where I have to run Zope on Windows. This has worked pretty well for me because Zope 2.7 used my "system" instance of Python 2.3.x. At least, that's my assumption since runzope.bat pointed at the system instance of Python. This setup was nice because it made it very easy to install Python modules (like PIL). When I ran the module installation executable, it would find my system instance of Python in the registry and install the module properly. With Zope 2.8.1, the "default" setting seems to be using the embedded Python interpreter that came with Zope. This is a problem because the embedded versions of Python do not appear in the registry, making it impossible to install a lot of Python modules on Windows. I thought that the following script (http://effbot.org/zone/python-register.htm) would allow me to add embedded versions of Python to my registry. However, you can't add more than one major version of a python release (2.2, 2.3, etc) to the registry. So if my system version of Python is the 2.3.x branch, and I want to use an embedded 2.3.x version of Python with Zope, then I'm out of luck if I want to install many Python modules with it. I can still edit runzope.bat so that it points at the system instance of Python, but I don't know if this is a best practice. Has anyone had any luck installing Python modules in an embedded version of Python on Windows? Is there a better way to work around this than referencing the system version of Python in the runzope.bat file? Thanks in advance for any help! Tom Purl

FileSystemSite does not register file extension
by Marco Bizzarri 16 Sep '05

16 Sep '05

Hi all. I'm using the FileSystemSite product in a pure Zope application. Inside it, I'm registering some extensions (gif, png, jpg, etc.) in order to work with a subclass of FSImage. The problem now is that the registration works for all extensions but the gif one. This has changed from one day to another. Now, I understand this is something we did, but I've no clue in what we could have changed. Works = With a png, I've my FSImage subclass used. With a gif, I've the FSImage used. Also, with the gif I've the '.gif' added to the id of the object, while with the other image I don't have it. Any suggestion? -- Icube Srl http://www.icube.it/

zope is selfrestarting: can't uninstall a product!
by daniele 16 Sep '05

16 Sep '05

Hi! I've asked to the italian mailing list, but no reslut... so I try here. About 2 weeks ago I found a memory leak in a product for zope (ZPhotoSlides). Being furious about that, I went to the Products folder and deleted the folder containing the product, and moved all the photos to a beautiful BINS external gallery. The memory leak was corrected: the average RAM usage dropped from about 700MB to 65MB! But suddenly another problem raised: the zope server was restarting itself about every 30min! I went to events.log and found that before the "Shutting down with error code 1" lines, there where an error about a ZPhotoSlides module it couldn't load. So, I downloaded again the ZPhotoSlides product and placed it in the Products directory. Then I went to each of my plone sites and manually uninstalled the ZPhotoSlides product with the uninstall tool. Finally, I went to Zope Management Interface and deleted the ZPhotoSlides folder in Products, and the same on the Products folder on the filesystem. Then I restarted zope and all seemed OK. But, the restarting period is only bigger... about 3-6h. Then Zope crashes again and restart itself, for the same error (can't find a ZPhotoSlides module). Note that I didn't deleted the photo albums that where stored in the db, because there where ratings, comments etc... and I hope to recover them at a future ZPhotoSlides release. SO, WHAT SHOULD I DO????? I want Zope to FORGET about the EXISTENCE of ZPhotoSLides product, WITHOUT loosing all my data!!! Thanks!

The FCGI code has not been touch for ages, nobody cares about the FCGI code, serious people don't use FCGI with Zope...so you should follow the straight forward approach and use a reverse proxy (which is documented in a bunch of documentation). -aj

Zwiki conflicts with my product
by Nicholas Wieland 16 Sep '05

16 Sep '05

I've developed a FS based product, and now I'm preparing the environment to put it in production. After copying the product directory in Zope's Product folder Zope doesn't start anymore, for reasons that frankly I don't understand because it "conflicts" with Zwiki (and I don't use anything from that product). 2005-09-15T12:05:37 ERROR(200) Zope Could not import Products.ZWiki Traceback (most recent call last): File "C:\Program Files\Zope-2.7.7-final\lib\python\OFS\Application.py", line 6 73, in import_product product=__import__(pname, global_dict, global_dict, silly) File "d:\Zope-Instance\Products\ZWiki\__init__.py", line 12, in ? import ZWikiPage, ZWikiWeb, Permissions, Defaults File "d:\Zope-Instance\Products\ZWiki\ZWikiPage.py", line 63, in ? from Regexps import url, bracketedexpr, doublebracketedexpr, \ File "d:\Zope-Instance\Products\ZWiki\Regexps.py", line 93, in ? uppercase_uc = unicode(string.uppercase) UnicodeDecodeError: 'ascii' codec can't decode byte 0x8a in position 26: ordinal not in range(128) Traceback (most recent call last): File "C:\Program Files\Zope-2.7.7-final\lib\python\Zope\Startup\run.py", line 50, in ? run() File "C:\Program Files\Zope-2.7.7-final\lib\python\Zope\Startup\run.py", line 19, in run start_zope(opts.configroot) File "C:\Program Files\Zope-2.7.7-final\lib\python\Zope\Startup\__init__.py", line 52, in start_zope starter.startZope() File "C:\Program Files\Zope-2.7.7-final\lib\python\Zope\Startup\__init__.py", line 231, in startZope Zope.startup() File "C:\Program Files\Zope-2.7.7-final\lib\python\Zope\__init__.py", line 47, in startup _startup() File "C:\Program Files\Zope-2.7.7-final\lib\python\Zope\App\startup.py", line 45, in startup OFS.Application.import_products() File "C:\Program Files\Zope-2.7.7-final\lib\python\OFS\Application.py", line 6 50, in import_products import_product(product_dir, product_name, raise_exc=debug_mode) File "C:\Program Files\Zope-2.7.7-final\lib\python\OFS\Application.py", line 6 73, in import_product product=__import__(pname, global_dict, global_dict, silly) File "d:\Zope-Instance\Products\ZWiki\__init__.py", line 12, in ? import ZWikiPage, ZWikiWeb, Permissions, Defaults File "d:\Zope-Instance\Products\ZWiki\ZWikiPage.py", line 63, in ? from Regexps import url, bracketedexpr, doublebracketedexpr, \ File "d:\Zope-Instance\Products\ZWiki\Regexps.py", line 93, in ? uppercase_uc = unicode(string.uppercase) UnicodeDecodeError: 'ascii' codec can't decode byte 0x8a in position 26: ordinal not in range(128) My product depends on Reportlab and PIL, nothing else, I don't have a clue of what's happening here.
