New External Editor release 0.9
by Chris McDonough 21 Jun '05

21 Jun '05

Since Casey Duncan, the original author of Zope External Editor is happily hacking away on other things at a new job, I figure I might as well pick up maintenance of this product. The new location for External Editor releases will be: http://plope.com/software/ExternalEditor/ A new release (0.9) is available at that location and the changes for the release are visible at http://plope.com/software/ExternalEditor/CHANGES-0.9.txt . Most changes in this release are aimed at improving zopeedit behavior under Windows. Have fun! - C

ZPT & contents slot
by John Poltorak 21 Jun '05

21 Jun '05

If I create a macro which defines a slot called 'content', is there any way to have that slot populated by a file with a specific name if it exists in a folder? What I'd like to do is create a structure text file, in each of the folders A B C and have it automatically loaded into a content slot of a master template whenever the options A B C are selected. Can I do that, and if so how? I have spent all day looking at ZPT references and have no idea if what I'd like to do is possible. -- John

Zope External Editor Problem
by hpinson＠indepthl.com 21 Jun '05

21 Jun '05

Hello. I am having a problem with Zope External Editor 0.8 - the helper app running on W2K. This problem occurred on upgrade from the previous version. When I lauch the external editor, by clicking the pencil, MS Word lauches (and if I save, badly mangles the HTML. In ZopeEdit.ini my editor setting has not changed: # Uncomment and specify an editor value to override the editor # specified by the operating system editor = C:\Program Files\TextPad 4\TextPad.exe I used to be able to change this path to Dreamweaver as well, but when I do that, only MS Word launches. What could account for this? Is there a solution to get Zope External Editor working as it did prior to the upgrade?

The macro page (from Help! > Zope Help > ZPT Reference > metal:define-slot) we will call 'master.html':: Hello World A client page (from metal:fill-slot):: Hello Kevin Bacon In CMF/Plone/etc, one would usually say 'context' instead of 'container' because of the skins sytem. It is not a great intellectual leap to replace "Hello" with header-type page structure, and replace the whitespace after the slot with footer-type structure. --jcc -- "Building Websites with Plone" http://plonebook.packtpub.com/ Enfold Systems, LLC http://www.enfoldsystems.com

Hello, list. I have a problem with my product. I use Zope 2.7.5 and Plone 2.0.5.

installation problem

Hi- I got zope 2.8 installed on fedora core 4. Whenever I execute this command to start zope /usr/local/zope/instance/bin/runzope, I get this error: Error: The object named by "DBTab.ClassFactories.autoClassFactory" could not be imported Traceback (most recent call last): File "/usr/local/zope/lib/python/Zope2/Startup/datatypes.py", line 93, in importable_name package = __import__(n, g, g, component) File "/usr/local/zope/lib/python/DBTab/ClassFactories.py", line 18, in ? import OFS.Uninstalled File "/usr/local/zope/lib/python/OFS/Uninstalled.py", line 16, in ? import SimpleItem, Globals, Acquisition File "/usr/local/zope/lib/python/OFS/SimpleItem.py", line 25, in ? import Globals, App.Management, Acquisition, App.Undo File "/usr/local/zope/lib/python/Globals.py", line 23, in ? import Acquisition, ComputedAttribute, App.PersistentExtra, os File "/usr/local/zope/lib/python/App/PersistentExtra.py", line 16, in ? from class_init import default__class_init__ File "/usr/local/zope/lib/python/App/class_init.py", line 14, in ? from AccessControl.PermissionRole import PermissionRole File "/usr/local/zope/lib/python/AccessControl/__init__.py", line 17, in ? from Implementation import setImplementation File "/usr/local/zope/lib/python/AccessControl/Implementation.py", line 98, in ? setImplementation("C") File "/usr/local/zope/lib/python/AccessControl/Implementation.py", line 51, in setImplementation from AccessControl import ImplC as impl File "/usr/local/zope/lib/python/AccessControl/ImplC.py", line 29, in ? from ImplPython import RestrictedDTML, SecurityManager ImportError: No module named ImplPython (line 914 in file:///usr/local/zope/instance/etc/zope.conf) For help, use /usr/local/zope/lib/python/Zope2/Startup/run.py -h I noticed that this affected other people from some discussions, but I couldn't find any solution. Does anybody have an idea where I can start? My buddy got his working on fedora core 4 fine, so it shouldn't be a problem. When I first compiled zope, I used this command. "./configure --prefix=/usr/loca/zope --with-python=/usr/bin/python2.4". Any help would be much appreciated! -Tyson

ZMYSQLDA 2.0.9 lock problem
by Dennis Allison 21 Jun '05

21 Jun '05

IE, Zope 2.7.6, Python 2.4.1, MYSQLDA 2.0.9 One of our developers is reporting a curious problem, which I have not been able to track down. It appears to be threading related, somewhere in the ZBMYSQLDB adaptor. The database connection string is bare of transaction indicators. The database is local. All tables are MyISAM which is non-transactioal. Unfortunately the user does not remember the exact sequence of events which generate the problem so I am unable to duplicate. What we do know is that the problem occurs at the beginning of a development session begun with a cold boot of the client machine and a fresh browser and it occurs once and only onece during the development session. The developer normally has two active Zope threads going--one working with the application and one working with the ZMI. He moves between them using the Open/View tab and other buttons. He reports that the first time he moves focus from the ZMI to the application, he gets the following error: ------------------------------------------------------------------- Time 2005/06/20 07:12:03.478 GMT-7 User Name (User Id) XXXX (XXXXX) Request URL http://xxx.xxxxxxxx.com/logged_in Exception Type error Exception Value release unlocked lock Traceback (innermost last): * Module ZPublisher.Publish, line 107, in publish * Module Zope.App.startup, line 222, in commit * Module ZODB.Transaction, line 260, in commit * Module ZODB.Transaction, line 377, in _finish_many * Module Shared.DC.ZRDB.TM, line 59, in tpc_finish * Module Products.ZMySQLDA.db, line 376, in _finish error: release unlocked lock -------------------------------------------------------------------- The lock being released is a transactional lock. None of our locks should be transactional locks, given our setup. I traced through the __init__() method for DB and did not see how transactional locking could be specified so the lock relaease code could run--I must be missing something. No thread in our system uses transactional locking as the tables do no support transactions. The logged_in method references the MySQL database in several places; a couple of them are compound queries where multiple queries are joined by "<dtml-var mysql_delimiter>" values. Many of our queries use this in combination with the "use <database name>" SQL query. The system is using ZODB filestorage (Data.fs) with ZEO and is pretty much out of the box. Has anyone else encountrered a similar problem. Any suggestions as to how to find this bug?

developing with zmi: how to move a patch from data from devel to live?
by gabor 20 Jun '05

20 Jun '05

hi, my problem is the following... imagine that you develop something for the customer using zope. while developing you use the ZMI a lot... to set some settings, to create python scripts and so on. you do this on the 'devel' server. then you deliver the solution to the customer (to the 'live' server). you can simply copy the data.fs stuff to the live server. after some time the either customer wants some new features, or there's a bug to fix or something like that. now you create the fix/improvement on the devel server. but now how do you move the improvement/fix to the live server? you cannot just copy the data.fs over. the customer already has some content/data in it... one way seems to be to not use the ZMI at all. you create an install python script, which calls the methods of the ZMI interface. this way works, but it seems for me to waste my time. finding the right method that the gui calls to call it from the install script seems stupid for me. but it solves the problem. with the script i can really make the changes i need on the devel server. so, is there a solution where i can use the ZMI? how do you solve this kind of problem? gabor
