Opening Old .zexp Files
by Susan Day 22 Mar '10

22 Mar '10

Hi; I have inherited some very old *.zexp files that I can't open in a Zope instance. Apparently they were built on 2.10 or even older. The problem appears to be that there were all sorts of products packed into the Products folder that crash everything and I don't know which ones are needed. How do I begin to dig into this mess? TIA, Susan

Dieter Mauer's Reference Product
by Brian Brinegar 16 Mar '10

16 Mar '10

Our university relies heavily on a Zope product based on Dieter Maurer's "Reference" product. Recently, we upgraded from Zope 2.9.6 to Zope 2.11.x and found some changes in behavior. In short the Reference product creates a Symlink like pointer in the Zope hierarchy. Dieter's product can be found on his site at: http://www.dieter.handshake.de/pyprojects/zope/index.html#bct_sec_5.9 First, the security machinery now prevents access to attributes of References through page template path notation. For example, the following fails: tal:content="container/MyReference/property_name" Traceback: ... * Module zope.tales.expressions, line 217, in __call__ * Module Products.PageTemplates.Expressions, line 133, in _eval * Module zope.tales.expressions, line 124, in _eval * Module Products.PageTemplates.Expressions, line 82, in boboAwareZopeTraverse * Module OFS.Traversable, line 301, in restrictedTraverse * Module OFS.Traversable, line 232, in unrestrictedTraverse __traceback_info__: ([], 'property_name') Unauthorized: You are not allowed to access 'property_name' in this context Interestingly, the same access via dot notation works: tal:content="python:container.MyReference.property_name There were substantial changes to Traversable.py between versions which seem to cause the problem. Any suggestion on how to fix this would be greatly appreciated. Second, through path notation or URL traversal, References under the previous version of Zope would default to using methods / objects within the target before falling back to acquisition. Under Zope 2.11 acquired methods/objects take priority (only when traversed). For example, assuming there is an index_html in the root as well as in the target, and using the following code: tal:content="container/MyReference/index_html/absolute_url_path" Zope 2.11 yields the path to the acquired index_html: /index_html Zope 2.9.6 yields the path to the index_html in the target: /Path/To/Target/index_html Again, through python, both yield the second, desired output. I realize this is an obscure product, and the changes seem to have to do with the Five implementation. At this point we are looking for options to restore the desired functionality which does not require perpetually running Zope 2.9.x One option may be to change everything to dot notation, however I would at least like to understand why this change occurred. Thanks for reading, -- Brian Brinegar Web Services Coordinator Engineering Computer Network

questions about migrating forwards
by Andrew Watkins 11 Mar '10

11 Mar '10

Hi list We have a legacy web service that is running on Zope 2.6.2 with Python 2.3.3 For various reasons - security, maintenance etc we have decide to try migrating this forward to a current version of python and zope. e.g. Python 2.6 + Zope 2.12.2 I have a new clean SUSE linux 11 installation with the correct python, setuptools and I am using virtualenv to create a sandbox I have installed the zope 2.12.2 and configured it in much the same way as the older system - (zeo with two data files, + 1 zope instance.) All is good and I can start up the instance and access the management pages. My next step is to get the Products list that we were using running. Here I have run into two problems 1. ExternalFile This fails to load with the error 'ImportError: No module named Interface' (stack trace below) I tested this with zope 2.11.4 and it works ok. 2. ZMySQLDA This fails with the message 'ImportError: No module named _mysql' again this works ok on zope 2.11.4 So I guess there is a key step that I am missing out or a path, or installation that is required. The main difference is that 2.12 is installed using virtualenv and then easy_install e.g. bin/easy_install -i http://download.zope.org/Zope2/index/2.12.2 Zope2 Are there known incompatabilities with these Products ? or is my installation just not quite right.

quickinstaller strange behavior
by iarly selbir | ski0s 02 Mar '10

Hi there, Looking quickinstaller on website instance I have here, I noticed one thing strange, the product CMFSquidTool has no version for column "Version at install time" and "Product version" has the version 1.3.3 but red highlighted, looking at other instance with other site all seems ok, I did send a screen: http://picasaweb.google.com/iarlyy/Oops#5444028086556924162 ( with error ) http://picasaweb.google.com/iarlyy/Oops#5444028087228029922 ( thats ok ) Does someone experienced with that? Thanks in advance. Regards, - - iarlyy selbir | ski0s :wq!

japanese encoding
by Aaron Maupin 01 Mar '10

01 Mar '10

Hi guys, I'm having trouble installing and using the japanese codecs (from http://www.python.jp/pub/JapaneseCodecs )with Zope on a shared host. I just can't seem to get the encodings available for the python used by the Zope install. Or, that is, I have installed the codecs and can 'import japanese' but whenever I try something like the following in a Python script: ---- import japanese #works print japanese #<module 'japanese' from '/home/USERNAME/webapps/zope/zinstance/parts/instance/lib/python/japanese/__init__.pyc'> #however there's nothing in /home/USERNAME/webapps/zope/zinstance/parts/instance/lib/python/ except a README.txt saying this directory will hold additional installed packages... should there be something here? text = 'blah blah' #okay text = unicode(text, 'utf-8') #okay text = text.encode('japanese.iso-2022-jp') #fails with lookuperror ---- LookupError: unknown encoding: japanese.iso-2022-jp This error also happens in an External Method. I have previously installed these codecs on an older version of Zope (Zope-2.7.0) (old-style instance) and Python (2.3.4) on a dedicated server, but am at a loss as to how to go about it with a Zope buildout on a shared host (Zope 2.10.9 on Python 2.4.3). The guys at Webfaction are also at a loss, and suggested I ask here. Anyone have any ideas? Aaron

few days ago my I'm getting this errors when trying logging on /manage, googling I don't found any reasonable solution and/or information about, only thing was, "restarting zope instances works", thats true Traceback: 2010-02-24T09:43:09 ERROR Zope.SiteErrorLog http://www.mywebsite.com/login_form Traceback (innermost last): Module ZPublisher.Publish, line 125, in publish Module Zope2.App.startup, line 238, in commit Module transaction._manager, line 96, in commit Module transaction._transaction, line 395, in commit Module transaction._transaction, line 498, in _commitResources Module ZODB.Connection, line 726, in tpc_vote Module relstorage.relstorage, line 711, in tpc_vote Module relstorage.relstorage, line 686, in _vote Module relstorage.relstorage, line 593, in _prepare_tid Module relstorage.adapters.mysql, line 506, in start_commit Module relstorage.adapters.mysql, line 672, in _hold_commit_lock StorageError: Unable to acquire commit lock I looked at the code and this function _hold_commit_lock has the following SELECT statement: SELECT GET_LOCK(CONCAT(DATABASE(), '.commit'), %s) I tried to reproduce it querying manually but it looks like an unknown command, and other point, I don't know what Zope put in %s variable. Does anybody already had this problem? Thanks for any reply. Regards, - - iarlyy selbir | ski0s :wq!
