Someone probably needs to adopt this orphaned >child. (I think maybe Amos wrote it, Amos?) Belated thanks on this help with ExternalObjects, Michel. I got this working with our ZPublisher/PCGI objects into zope, but I'm stuck on one issue: we encode the HTTP session in the URL, and have a dictionary class that is invoked to get the session object from a __getitem__() call. It works file with ZPublisher but isn't working with ExternalObjects in Zope. A sample URL is: localhost/Zope/sess/Z8Q/home ...where sess is an external object declared in zope containing a dictionary with an entry for Z8Q. I am using the old BoboDictionary, subclassed to override __getitem__() with code to look up the Z8Q key and return a session object. I also set __getattr__ = __getitem__ ... Michel, Amos, anyone -- ideas for what's going wrong, or what else I need to do? (Error output below.) TIA, Michael --------- Debugging Notice Zope has encountered a problem publishing your object.

Propertysheet not handeling properies with same name
by Jason Spisak 02 Jan '00

02 Jan '00

Zopsters, I have a ZClass instance that can be created inside another ZClass instance. Both have different propertysheets with one property name that is the same. When I call manage_changeProperties on the child 's property sheet, is doesn't change the child's property, it changes the parent! Parent_properties myProperty:tokens Child_properties myProperty:tokens When I call <dtml-call "propertysheets.Child_properties.manage_changeProperties( myProperty=REQUEST['myProperty'], )"> *Parent_properies* myProperty changes to REQUEST['myProperties'], not the one which was called. Can/Has anyone duplicate this? All my best, -- Jason Spisak webmaster(a)hiretechs.com

New info for ZCatalog and CatalogAware classes, and Question
by Bill Anderson 30 Dec '99

30 Dec '99

This seems to apply to two howtos: (A) How-To: Creating a CatalogAware ZClass (B) How-To: Inheriting from ZCatalog as a Container So I thought I would post it here so that both authors, and the rest of the dev community can see it and comment on it. I apologize for any roughness, I am hoping one or both of the howtos would be updated to reflect the new data. Alternatively, I could make a seperate howto if needed. What I was doing: I am working on a product (KnowledgeKit v2.0) that has a root container inherited from ZCatalog, and has Catalog_Aware Objects inside of it. The basics of what I did can be extrapolated further for other circumstances. For the Catalog_Aware object: In the add_form, I added a hidden variable, called 'catID', and gave it a value: <input type=hidden name=catID value="<dtml-var "PARENTS[0].id">"> This will work when the object to be added form is under the Container Object. See below for alternatives I have come up with. Then, in the constructor method, I modified the code in HowTo A to be: <dtml-call unindex_object> <dtml-call "manage_editCataloger(catID, REQUEST)"> <dtml-call index_object> The benefit is that you can use the Catalog object (FooContainer in this example) normally, ie. without adding the 'Catlog' DTML Method to the Container object. Additionally, one could make a catalog in the root of the site, which indexes every ZCatalog on the site, looking only for 'id', and create a dropdown list on the object's add_Form to select the catalog to index to. Look for an update on this with 2.0 of The KnowledgeKit. I believe this answers one of the todo parentheticals in HowTo A: (To do: how about adding a drop-down list to choose a catalog? Can I register a class instance in several catalogs?] <ramble> Regarding the latter question there, is it possible to index in one catlog, and then index in another? If so, you could do it by setting the catalogue to one, indexing/modifyin, and then setting the catalog to another, and repeating? </ramble> Question: Are there any effects of making a ZClass which is also Catalog_Aware? IOW, does it work? Does it break anything?

PLS HELP Zope: hangs + instable
by aeneas 30 Dec '99

30 Dec '99

Hi, We've just recently started www.linuxvideo.org with Zope and run into serious problems with our Zope Installation - Zope just hangs after 2-3 days running. :( First our configuration: 2 x Intel Celeron 433MhZ Processor 128MB RAM Linux 2.2.13 Zope 2.1.1-src (we had the same problems with 2.1.0, We've bound Zope to just 1 of 2 ip addresses on our system. We run the plain Zope Server on Port 80) Python 1.5.2 Problem description: After some time of running flawlessly, our Zope installation hangs without any error message. If you want to connect to www.linuxvideo.org via your browser you get an endless: "HTTP request sent; waiting for response.". Telnet to linuxvideo.org on port 80 _is_ possible: When I "telnet linuxvideo.org 80" and type some gibberish, after some time the Medusa webserver reacts: --snip-- HTTP/None 400 Bad RequestServer: Medusa/1.13 Content-Type: text/html Content-Length: 136 Date: Thu, 30 Dec 1999 10:42:30 GMT --snip-- ... My faked request is logged in Z2.log too (2nd line): 62.188.156.147 - - [29/Dec/1999:11:54:21 +0200] "GET /04devel/01index_status HTTP/1.0" 200 10117 "http://www.linuxvideo.org/04devel/05index_res" 195.34.156.176 - - [30/Dec/1999:10:42:30 +0200] "kjdsalfjklsdjfkalsfjsfdfsdafds" 400 269 "" "" BUT no page will show up in any browser. Zope processes are working normal (no 100% CPU usage, ect.). What can we do to prevent Zope from hanging like that again. Do you need some more debugging infos? (Please tell me what/how) 1000x Thanks in advance Dominik Schnitzer d.schnitzer(a)gmx.at

ObjectManagers and their children

I also feel a little worried that a future version of a class might add a class attribute which clashes with a pre-existing instance attribute added by the user. The protection you describe won't help if the attribute is added in an earlier version, before that class attribute was added. Has anyone else explored this potential problem?

problems upgrading zope
by Sebastian Luehnsdorf 29 Dec '99

29 Dec '99

hi everyone! i attempted to convert a Data.bbb (Zope-1.10.3, ZODB2) database file to a Data.fs (Zope-2.1.1, ZODB3 ?) file using the following syntax: python utilities/bbb.py -x -f Data.fs Data.bbb which returned "corrupt database" error messages. this happened on three different occassions and at very early positions of the database file, i.e. 0 or 9. reversing the reading from back to front using the -e option did not help either. the original database files seem to be fine. at least the 1.10.3 servers are up and running without any problem. the server is an intel box, running suse linux 6.2. we are running python 1.5.2. is this a known problem and does anyone have a workaround. please excuse if this issue was raised here earlier. it seems that i am not receiving all postings from the mailing lists :( please also 'cc' your replies to my e-mail address (basti(a)beehive.de) for the same reason. ciao, basti -------------------------------------------------------------------------- sebastian f. luehnsdorf beehive elektronische medien gmbh -------------------------------------------------------------------------- http://basti.beehive.de http://www.beehive.de mailto:basti@beehive.de mailto:service@beehive.de http://www.zope.de fon: (+49 30) 84 78 20 http://www.i-surf.de fax: (+49 30) 84 78 22 99

etcUserFolder

29 Dec '99

Mike, How do I get the etcUserFolder out of a Zope if it won't allow a login. I've tried a crty module for my system, and it won't let me into the mangement interface. Help? I figured version 1.0.2 was stable enough not to deny me access right off the bat. All I did was install it, and it kicked me out. Ugh. Happy New year, Everyone.

.pyo files in CVS
by Robin Becker 29 Dec '99

29 Dec '99

imho it's a bad idea to have non source files in the CVS tree. I have just seen some in ./lib/python/Products/PythonMethod/zbytecodehacks/tests I guess these aren't required, but wouldn't it be a good idea to remove them? -- Robin Becker
