Possible disaster upgrading to 2.2.4
by Jonathan Cheyne 28 Nov '00

28 Nov '00

Hi all, been very very foolish and didnt backup my entire zope installation prior to untarring the 2.2.x to 2.2.4 diff (binary) tgz. after restarting i get a message "couldnt import product.ZDbase" and one or two others, then screeds of oid errors then a start. But the site is a bit slaughtered because anything basedon a zclass I created durny work. even though it is there and not shown as brokwen itself. the only two shown as broken are zdbase and zdconfera. my zclass is only based on ZObject, CatalogAwareBase, _ZClass_for_Renderable so I am a bit stumped. when I try to list in magament view, the contents of any folder containing 1 or more instances of my zclass, the console shows things like: ------ 2000-11-28T14:37:38 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\000k' Traceback (innermost last): File /home/zope/Zope-2.2.0-linux2-x86/lib/python/ZODB/Connection.py, line 448, in setstate File /home/zope/Zope-2.2.0-linux2-x86/lib/python/ZODB/Connection.py, line 213, in _persistent_load (Info: ) File /home/zope/Zope-2.2.0-linux2-x86/lib/python/ZODB/Connection.py, line 154, in __getitem__ (Info: ('\000\000\000\000\000\000\003\266', '(cExtensionClass\012ExtensionClass\012q\001(U\006ZDItemq\002(cZClasses.ZClass\012PersistentClass\012q\003cProducts.ZDBase.ZDiscussions\012ZDItem\012q\004cOFS.SimpleItem\012SimpleItem\012q\005tq\006}q\007(U\004iconq\010UWControl_Panel/Products/ZDiscussions/ZDTopic/propertysheets/methods/ZDItem%20/ziconImageq\011U\012_p_changedq\012K\001U\007__doc__q\013U\021ZDiscussions Itemq\014U\006_p_oidq\015U\010\000\000\000\000\000\000\002Lq\016U\011meta_typeq\017U\021ZDiscussions Itemq\020U\016propertysheetsq\021(U\010\000\000\000\000\000\000\003\271q\022(NU\010\000\000\000\000\000\000\003\265q\023Qttq\024QU\012index_htmlq\025cZClasses.Method\012MW\012q\026NRq\027}q\030U$_ZClassMethodPermissionMapperMethod_q\031(U\010\000\000\000\000\000\000\003\272q\032(U\016OFS.DTMLMethodq\033cOFS.DTMLMethod\012DTMLMethod\012q\034ttq\035QsbU\016manage_optionsq\036(}q\037(U\005labelq U\012Propertiesq!U\006actionq"U\025manage_propertiesFormq#u}q$(U\005labelq%U\010Securityq&U\006actionq\'U\015manage_accessq(u}q)(h%U\004Viewq*h\'U\012index_htmlq+utq,U\012ziconImageq-(U\010\000\000\000\000\000\000\003\273q.(U\011OFS.Imageq/cOFS.Image\012Image\012q0tq1tq2QU\022__ac_permissions__q3)U\011_p_serialq4U\010\0030\226a\274;\204\314q5U\012__module__q6U\031*73biqpAI2QDa2iKPitv57g==q7utq8t.N.'))

Zope mailing list doesn't work
by Milos Prudek 28 Nov '00

28 Nov '00

Today, I can't change my options for zope(a)zope.org. I went to http://lists.zope.org/mailman/listinfo/zope, and it says that the document has moved to http://lists.zope.org/mailman/listinfo/zope, ad infinitum. If youa are reading this then I can post, but I cannot read since I have disabled delivery a few days ago and now I can't enable it due to the above mentioned problem. Thanks for any help, and please mail me directly -- Milos Prudek

Building Zope within a Virtual Server
by Norman Khine 28 Nov '00

28 Nov '00

Hello, The new zope site seems to be running very well. I have a virtual server account on which I had previously installed zope 2.2.2 which was later successfully upgraded to 2.2.4, unfortunantly I had problems in setting up MySQLdb. I have now removed zope and python 1.5.2, re-installed python2.0, within my domain. Which is part of the larger domain. So my root directory is not in / but is in /usr/home/mydir/ , within which I have installed python2.0 I have changed the .login file so that the path for the new python installation is available through out my domain. So that when I type python2.0 at the # I can use the python interpreter, this seems to work OK. Therefore my question/s are: If there is python on the root machine as well as on the virtual servers, so that both python and python2.0 will run from the command prompt, will this cause problems when I install the new virsion of zope 2.2.4? Do I need to change any configurations to the makefile or setup so that zope knows it is using python2.0 and not the root installation of python, if so what will this changes be? I would like to configure the zope installation so that it is set up with an existing web server, currently Apache 1.3.12 as per your How-To by http://63.102.49.33/Members/maryniak/zope-on-suse64-howto by maryniak, but I am unsure as to where in the procedure I specify that I have python already installed? Do I need to specify this before? And finally, do I need the Python MySQLmodule extension be installed before Zope or after? Many thanks for your help Norman

dtml as a server side scripting language is not going to change anything dynamically on your page. Maybe you mean DHTML. In IE everything is in the DOM and can be changed. Netscape is not thorough, and I don't think there is a hook that will change a.visited, et al. But you could try. IE has a links collection, like .images and .all

2.2.4 upgrade query
by Jonathan Cheyne 28 Nov '00

28 Nov '00

Further to my paniced posting earlier, I reinstalled 2.2.0, copied over my data.fs* and various products and everything fired up fine but i did one experiment (following on from Chris) - i didnt install zdiscussions. This resulted in major oids errors and my broken zclass as before/ install zdiscussions and bingo i am back in business. so. two questios: 1. why does my zclass appear to require zdiscussions when it is not based on it? 2. does 2.2.4 contain some parts of what was previously the standalone zdiscussions product? Is this an obsure backwarsd dependency break kindo of thing? I will stick to 2.2.0 for now, methinks. cheers Jonathan

ZODBC configuration problems
by paul_s_johnson＠urscorp.com 28 Nov '00

28 Nov '00

Alas, I am but a Zope newbie and need help getting my database connections to work. I have previously configured the ODBC Data Source Administrator to link Access mdbs with the PERL DBI module and it has worked with no problems. I have installed the ZODBC product and in the Zope database connection window all the names of the ODBC data sources that have been configured show up in the listbox. Upon attempting to add any of the data sources I receive the error "Invalid connection string" except for one of the databases that Zope does accept. Upon testing this database connection with a test query I get the following error: Error Type: sql.error Error Value: ('42000', -1907, "[Microsoft][ODBC Microsoft Access 97 Driver] Record(s) can't be read; no read permission on 'ProjectSheets'.") The permissions on this database are such that any anonymous user can access its data so the error message appears to be inaccurate. I double checked the db permissions to make sure this is the case. I am running Zope on NT 4.0 and using Access 97. The logged-in user on the webserver is not a member of any Access-related workgroups so this eliminates most security-related access issues (I think) and none of the databases are passworded. There's some flakiness going on here. Any recommendations for isolating and resolving these problems? Thanks, P. Johnson

Re: [Zope] PoPy and Delete results
by Dieter Maurer 28 Nov '00

28 Nov '00

Chris Gray writes: > In psql a delete command returns a count of the number of rows > deleted. Is this returned result available to a ZSQL method using PoPy or > PyGreSQL? I think, Zope should pass integer results from SQL commands. But I fear, it does not. When I looked at the code (quite some time ago), I had the impression, that Zope does only pass sequence results. Integer results are translated into 'None'. Dieter

I am trying to change the colour of links dynamically using dtml. However, I cannot find the right incantation to change my links using an inline style except for <a href=A style="color: red">A</a> I really would like to be able to set the link, active and visited colours. I can do this using a class eg <head> <style>  </style> ..... <a class=badLink....> works -- Robin Becker

Factory location and Add box pollution
by Stefan H. Holek 28 Nov '00

28 Nov '00

I want to create a folderish ZClass to contain all my project specific ZClasses. The idea is to only have them show up when inside my projectfolder. Just like the ZClass object only shows up inside a product's folder. Well, when I derive from OFS:Folder I do get all the global stuff, but _not_ my included ZClasses in the Add box. OTOH, deriving from ZClasses:ObjectManager gives me my ZClasses, but _not_ the global objects (DTML Methods, ...) Deriving from _both_ gives me the behavior of whichever was named first. I have seen the LocalFactory product, but this would force me to move the factories and constructors out of my ZClasses. Its very existance though might mean what I want is impossible :( Lost, Stefan -- Things work better when plugged in
