[Zope-dev] Installer for Windows (quick question)
Since I'm going to be building the installer for Windows I would like to quickly ask if anyone expects multiple Zope installs to live side-by-side. The existing installer atempted that but I don't believe it was very successful. I would like to know if anyone has multiple Zope installations on Windows side-by-side and if they consider that important. -- Sidnei da Silva Enfold Systemshttp://enfoldsystems.com Fax +1 832 201 8856 Office +1 713 942 2377 Ext 214 ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

I would like to know if anyone has multiple Zope installations on Windows side-by-side and if they consider that important. I find it quite useful for testing e.g. with Plone 2.1 and 2.5 and 3.0, which require different Zope versions... I don't have an understanding of how hard it is to do, though - but I certainly have no idea how I'd build Zope myself on Windows and therefore manage my instances myself. I'd be happy if only the last installed one owned the *service*, if I could use runzope.bat on the others.

I would like to know if anyone has multiple Zope installations on Windows side-by-side and if they consider that important. Yes and yes. Same as Martin Aspeli's reasons: testing on multiple plone versions. I think the main thing is to be sure that the installation doesn't add any zope specific folders to PythonPath in the registry. The Plone installation for example adds (or added) some folders to PythonPath which meant that multiple plones using the same major python version would try to share parts of the Plone installation. Not adding folders to the pythonpath registry key allows coexistence, and there are more than enough ways to add folders to pythonpath without using the registry. ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

I'd like to redirect each page in each old wiki to the corresponding page in the new location and I think that can be done. You can see the old wiki urls at http://wiki.zope.org/OldWikis . The new urls are http://wiki.zope.org/SAMEFOLDERID (except ComponentArchitecture is now zope3). So, how would we write this.

I issued that command at the prompt and got this:# import Products.MailingLoggerimport: unable to open X server `'.Is there something I should edit first? Like zope.conf? Your instructions seem to indicate first issue the command, then edit zope.conf. And I'm confused as to if I should be editing zope.conf or something else, because my zope.conf file doesn't look like, for example, an httpd.conf file, where one would have syntax similar to what you propose.

[Zope] What is an InvalidObjectReference?
Hello everyone,I'm sporadically getting the following error thrown as a result of a routine I've written.InvalidObjectReference: Attempt to store a reference to an object from a separate connection to the same database or multidatabase. I can often run this routine several times without a problem. After a fresh Zope (re)start, this error never happens on the first run. Once the problem does occur I need to restart Zope to make it go away. Can anyone tell me what this error actually means, and what bad practices could cause it?I've found a couple of hits about InvalidObjectReference: Attempt to store an object from a foreign database connection error in the archives, but I don't know how close this is to my problem. An example traceback would be:---2006-11-08T16:47:49 ERROR Zope.SiteErrorLog http://localhost:8080/WebSites/dev/test1/manage_publish Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module Products.DWT.WebBase , line 756, in manage_publish Module Products.DWT.WebBase, line 724, in manage_publish Module OFS.CopySupport, line 564, in _getCopy Module transaction._manager, line 110, in savepoint Module transaction._transaction, line 295, in savepoint Module transaction._transaction, line 292, in savepoint Module transaction._transaction, line 675, in __init__ Module ZODB.Connection, line 1012, in savepoint Module ZODB.Connection, line 526, in _commit Module ZODB.Connection, line 553, in _store_objects Module ZODB.serialize, line 407, in serialize Module ZODB.serialize, line 416, in _dump Module ZODB.serialize, line 341, in persistent_idInvalidObjectReference: Attempt to store a reference to an object from a separate connection to the same database or multidatabase ---I'm only dealing with one ZODB, so perhaps this is a multiple connection issue (although I have no idea how/why).In case it helps to know the context of the problem, I have a collection of objects I've written: 1) WebSite, based on OrderedFolder2) WebSection, based on OrderedFolder3) WebPage, based on ZopePageTemplate4) WebImage, based on Image.Each of these classes inherit a common base of functionality from a WebBase class. The manage_publish() method, defined in WebBase, copies the current object (one of #'s 2-4) to the same relative path within the context of another WebSite. This gives me a basic dev to live publishing process. Perhaps the most complex part of this routine is its ability to recurse. For example, a WebPage on the dev WebSite will first call its parent WebSection's manage_publish() if the parent WebSection doesn't exist on the live WebSite. Other things do happen during the process which might be causing this InvalidObjectReference, but if I can get a grip on what kinds of programming offenses causes this exception then I can make a more educated review of my code. I will happily provide a copy of the source if anyone is interested or thinks it will be useful.

Otherwise, it will raise Unauthorized with the intent that an unmotivated Unauthorized is better than giving access to some piece of information that should be protected.

You may try to return a wrapper that behaves the same way as the original object (by deriving from the respective type) but has __roles__ = None as additional attribute (which declares the object public). -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] What is an InvalidObjectReference?
Ok, I understand in theory what the problem is, I'm just not clear where in code this could be happening. I'm not consciously manipulating connections and I guess Zope is taking care of those low-level connection details with the ZODB for me. Can I programmatically determine whether an object is already loaded/cached by a different connection?Would it help to try isolate this routine to a single connection?*Can* I isolate this routine to a single connection? You know, I'm starting to think that my fancy little recursion between objects is what's royally screwing things up. A lot of loading of objects occurs here, possibly touching on the same objects between calls... Any other pointers/hints are welcome!Thank you Dieter and anyone else who can help out!GarthOn 11/9/06, Dieter Maurer [EMAIL PROTECTED] wrote:Garth B. wrote at 2006-11-9 11:21 -0500:I'm sporadically getting the following error thrown as a result of a routine I've written.InvalidObjectReference: Attempt to store a reference to an object from aseparate connection to the same database or multidatabase.This is in indication that you have introduced a persistency bug: It is very essential that you use a persistent object onlyin the context of the ZODB connection that loaded this object.Failing to fulfill this requirement can lead to several kindsof difficult to understand errors.
