XML Export Error and Patch
by Willi Langenberger 11 Nov '04

11 Nov '04

Hi! When i try to export a PluggableAuthService object as XML, (with ZMI Import/Export or with manage_exportObject?id=acl_users&download=1&toxml=Y) i get the following exception: Error Type: AttributeError Error Value: List instance has no attribute 'extend' [...] Traceback (innermost last): * Module ZPublisher.Publish, line 101, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module OFS.ObjectManager, line 504, in manage_exportObject * Module OFS.XMLExportImport, line 58, in exportXML * Module OFS.XMLExportImport, line 33, in XMLrecord * Module Shared.DC.xml.ppml, line 253, in load * Module pickle, line 872, in load * Module pickle, line 1209, in load_appends Seems that the xml export calls the "extend" method of an Shared.DC.xml.ppml.List object, which isnt implemented. The following patch (implement "extend" like "append") solves the problem (for me!): zope@bach-s17:~$ diff -u -U10 Zope-2.7.2/lib/python/Shared/DC/xml/ppml.py.ori Zope-2.7.2/lib/python/Shared/DC/xml/ppml.py --- Zope-2.7.2/lib/python/Shared/DC/xml/ppml.py.ori 2002-08-14 23:51:00.000000000 +0200 +++ Zope-2.7.2/lib/python/Shared/DC/xml/ppml.py 2004-11-10 23:05:55.000000000 +0100 @@ -209,20 +209,22 @@ class Sequence(Collection): def __init__(self, v=None): if not v: v=[] self._subs=v def __len__(self): return len(self._subs) def append(self, v): self._subs.append(v) + def extend(self, v): self._subs.extend(v) + def value(self, indent): \wlang{} -- Willi.Langenberger(a)wu-wien.ac.at Fax: +43/1/31336/9207 Zentrum fuer Informatikdienste, Wirtschaftsuniversitaet Wien, Austria

Re: Zope and Python 2.4
by Alan Milligan 10 Nov '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The reason I asked this question is because clients I talk to in the enterprise space are almost all exclusively RH9/RHEL clients, and many have major reservations about installing anything non-RH 'approved' as they feel they have some security assurances using this, and certainly RH are reasonable sincere with their efforts here. If ZC say Zope is approved and test with version X of Python, then this too has some weight in their minds. We have our own distro and stability within the flux of Zope, Plone and a large number of enterprise-targeted products is probably the major sales pitch. However, having to fork off the main Fedora branch in regard to Python dependencies (which directly affect Anaconda, up2date, GTK, and most of the desktop applets) has major implications for how we maintain our distro. So, I ask again, what is the official view on Python 2.4, and if there's a roadmap as to when it will become blessed.

Zope and Python 2.4
by Alan Milligan 10 Nov '04

10 Nov '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I followed the thread a week or so ago with great interest, in that substantially Zope is working with Python 2.4 However, RedHat have now released Python 2.4 in the Fedora development stream and it will ship with FC4. Does ZC have an official position upon this yet?

Zope 3 Users Mailing List
by Stephan Richter 09 Nov '04

09 Nov '04

Hello everyone, on popular demand from a couple of people we have decided to create a new Zope 3 Users mailing list that will serve to answer your questions about Zope 3. The Zope 3 developers have made a commitment to answer your questions in a timely manner. We hope that this way the generic Zope and Zope3-Dev mailing list will be disburdened from user-related questions. You can subscribe to the mailing list at: http://mail.zope.org/mailman/listinfo/zope3-users Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training

It's my first time, so tell me if I did something wrong. If I understand things correctly, 2.7 is still on the cvs? Should I check in the same fix there? //Lennart

Problems with allow_class and class built-in __dict__
by Manuel Markwort 05 Nov '04

05 Nov '04

hello, today i ran into a problem with zope. i've wrote some base-classes in c++, using Boost.Python (www.boost.org) to export them into a python-module. the module (.pyd-file) works fine with my python-interpreter (v2.3.3). i can import it, instanciate objects of my c++-classes and use their methods successfully. my module is aimed to extend one of my zope-products. in the current level of development, the module contains a first bunch of classes, which provide the basic functionality. so, i wanted to test my module not only with the commandline-interpreter of python, but in zope, as well. my setup runs zope v2.7.1 (win32, with python v2.3.3), which worked fine until today. i've started to write a new zope-product, making my module useable in zope. in the initializer-script i tried to allow my module and the classes in it on the usual way: <-- start: __init__.py --> from Products.PythonScripts.Utility import allow_module, allow_class allow_module("Products.ABPcWeb") allow_module("Products.ABPcWeb.ssl2du") <-- THE PYD FILE allow_class(PySslSet) <- allow_class(PySslEntry) | Classes in ssl2du.pyd allow_class(PyAccessSsl) | allow_class(PySslStatement) <- __version__ = "0.01" __product_name__ = "ABPcWeb" def initialize(context): pass <-- end: __init__.py --> the product is called 'ABPcWeb', and my .pyd 'ssl2du'. looks ok, i thought, but zope throws this error on startup: <-- start: zope-error --> Loading ABPcWeb ... ------ 2004-11-05T16:14:58 ERROR(200) Zope Could not import Products.ABPcWeb Traceback (most recent call last): File "C:\Program Files\Zope-2.7.1\lib\python\OFS\Application.py", line 660, in import_product product=__import__(pname, global_dict, global_dict, silly) File "C:\Zope-Instance\Products\ABPcWeb\__init__.py", line 8, in ? allow_class(PySslSet) File "C:\Program Files\Zope-2.7.1\lib\python\AccessControl\SecurityInfo.py", line 313, in allow_class sec.apply(Class) File "C:\Program Files\Zope-2.7.1\lib\python\AccessControl\SecurityInfo.py", line 165, in apply dict['%s__roles__' % name] = access TypeError: object does not support item assignment Traceback (most recent call last): File "C:\Program Files\Zope-2.7.1\lib\python\Zope\Startup\run.py", line 50, in ? run() File "C:\Program Files\Zope-2.7.1\lib\python\Zope\Startup\run.py", line 19, in run start_zope(opts.configroot) File "C:\Program Files\Zope-2.7.1\lib\python\Zope\Startup\__init__.py", line 51, in start_zope starter.startZope() File "C:\Program Files\Zope-2.7.1\lib\python\Zope\Startup\__init__.py", line 230, in startZope Zope.startup() File "C:\Program Files\Zope-2.7.1\lib\python\Zope\__init__.py", line 47, in startup _startup() File "C:\Program Files\Zope-2.7.1\lib\python\Zope\App\startup.py", line 45, in startup OFS.Application.import_products() File "C:\Program Files\Zope-2.7.1\lib\python\OFS\Application.py", line 637, in import_products import_product(product_dir, product_name, raise_exc=debug_mode) File "C:\Program Files\Zope-2.7.1\lib\python\OFS\Application.py", line 660, in import_product product=__import__(pname, global_dict, global_dict, silly) File "C:\Zope-Instance\Products\ABPcWeb\__init__.py", line 8, in ? allow_class(PySslSet) File "C:\Program Files\Zope-2.7.1\lib\python\AccessControl\SecurityInfo.py", line 313, in allow_class sec.apply(Class) File "C:\Program Files\Zope-2.7.1\lib\python\AccessControl\SecurityInfo.py", line 165, in apply dict['%s__roles__' % name] = access TypeError: object does not support item assignment <-- end: zope-error --> after searching the web for a possible solution of that problem, i realized that since python v2.2 the __dict__-attribute isnt a real dictionary, but a proxy-object. a direct access to __dict__ isnt allowed anymore, so zope cant do its work. to solve the problem, i've patched the following two files: <Zope-Root>/lib/python/AccessControl/SecurityInfo.py and <Zope-Root>/lib/python/App/class_init.py i've changed all direct-access commands invoking __dict__ to setattr()- and delattr()-methods. for example: --(SecurityInfo.py Line: 165)-- dict['%s__roles__' % name] = access now is: setattr(classobj, ('%s__roles__' % name), access) after that changes, the allowing of my module + classes worked well. now my question: is there a workaround for that problem without changing the zope-source ? is that 'bug' fixed in further versions ? best regards, Manuel Markwort

Psycopg and idle in transaction
by Marco Bizzarri 05 Nov '04

05 Nov '04

Sorry for crossposting this to APE mailing list, but I received no answer, and I think the issue can be of general interest. Can anyone confirm the following behaviour? I'm using zope 2.7.3, python 2.3.4, and Ape 1.0 I've just created the /sql mount point. I click on the /sql, and then I check to see any postgres process open. This is the result: emmebi@legoland:~$ ps axf | grep postgres | grep ape-test 10621 ? S 0:00 \_ postgres: postgres ape-test 127.0.0.1 idle in transaction emmebi@legoland:~$ The transaction is still open. I would like to know if anyone can confirm the problem. Regards Marco

Showstopper UnicodeDecodeError on Zope import???
by Nick Bower 05 Nov '04

05 Nov '04

I'm trying to import a zexp export (a Plone site actually) from a windows workstation to a zope server I built on Linux RH9 but it fails with a UnicodeDecodeError: ... Module Products.ZCTextIndex.Lexicon, line 69, in sourceToWordIds Module Products.ZCTextIndex.Lexicon, line 135, in _getWordIdCreate UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 5: orginal not in range(128). What is confusing is that the zexp *will* import to another linux zope build I have (on Mdk10) and sys.getdefaultencoding() and locale.getdefaultlocale() on the 2 linux machines are almost the same (the working one reports "en_GB, utf"/ascii and the non-working one reports "en_US, utf"/ascii), so I think this is a red herring. I can't for the life of me work out what is going wrong as I built python myself on both Linux machines exactly the same. Can anyone help me please??? Thanks, Nick

where is z2.py functionality in 2.7 world of zdrun.py?
by Royce 04 Nov '04

04 Nov '04

Got my zpublisher app working tied into z2.py under zope 2.5, and now looking at a move to FreeBSD and Zope 2.7. I had modified z2.py to hook in my external app as described in Amos' page http://www.zope.org/Members/Amos/ZPublisher. Problem is I don't know where to hook my zpublisher app into the 2.7 world. The snippet from z2.py (in my 2.5 setup) is: # Handler for a published module. zhttp_handler takes 3 arguments: # The name of the module to publish, and optionally the URI base # which is basically the SCRIPT_NAME, and optionally a dictionary # with CGI environment variables which override default # settings. The URI base setting is useful when you want to # publish more than one module with the same HTTP server. The CGI # environment setting is useful when you want to proxy requests # from another web server to ZServer, and would like the CGI # environment to reflect the CGI environment of the other web # server. zh = zhttp_handler(MODULE, 'z', HTTP_ENV) hs.install_handler(zh) # royce 8/22/04 sys.path.insert(0,'/app') # add MyModule to the Python path # create a handler my_handler = zhttp_handler('webapp/sessionMgr', 'bin/sessionMgr', HTTP_ENV) hs.install_handler(my_handler) # install it in the http server Can anyone point me to where in the 2.7 world I can do this equivalent? I searched the installation tree but wasn't able to find content using zhttp_handler() in the same way. TIA, Royce
