OT: for a software patent free Europe
by Dieter Maurer 19 Jun '00

19 Jun '00

Currently, software and human behaviour (business rules) cannot be patented in Europe. I think, this is good. It allows me to write software (and give it away) without the need to spend some months for patent investigations and money for legal advice. Part of the European Commission now plans to introduce patent practices known from the US in Europe. They include patents for stand-alone software, algorithms and human practices. A group of European software developpers and companies have joint forces to prevent this. We want to file a petition to the European Parliament.

PCGI Help!
by kwan 19 Jun '00

19 Jun '00

Hi: Sorry for sending out this one again. I actually send out couple email to ask this question. However, I still couldn't fix this problem. (Thanks Rik Hoekstra for the help) Did anyone got in the similar situation before? My problem is with the IIS + PCGI + ZOPE. The mechine I try to setup is NT 4.0 with sp 5, and IIS 4 It is actually our web site server which is currently hosting couple sites. It has multi-domain, multi-ips ( I don't know if this is the problem) I follow the HowTo for Zope.pcgi, start up with -p zope.pcgi, and bind the extension for .pcgi in IIS to pcgi-wrapper.exe %s which I am sure it work because I test it first on a test mechine. However I got "cannot lock database file" error. I check the proccess and var\z2.pid and var\pcgi.pid. When the browser access zope.pcgi .. IIS bring up pcgi-wrapper.exe which is correct I suppose. However, through the task manager/Proccess, I found out that another python.exe is started up. It seems pcgi-wrapper.exe try to bring up pcgi_publisher.py itself. and var\pcgi.pid got change to a different pid. Then, I follow what I found on the mail archive and set the PCGI_publisher=c:\zope\pcgi\dummy.py where dummy.py is just a empty file with size 0. Test again, I got error (102) cannot connect. I guess the problem is when Zope is init and startup, somehow the PCGI server(is it pcgi_publisher.py?) doesn't startup properly or even crashed. Therefore when pcgi-wrapper.exe try to connect, it found nothing, and therefore it starts its own PCGI server or got a no connection error as above. Althought I have this guess! I have no idea how to find out what's going wrong during Zope start up. I read something about the pcgifile.py so I try python pcgifile.py c:\zope\zope.pcgi and I got module not found I don't know where I can go from this point up. Or any suggestion that may be my guess it totally wrong and I should fix it in another path? Kwan

Re: [Zope] Problem with adding items to ZClass instance

Or me? > This is not so easy to answer. ZClasses do strange things to adding items. If your ZCLass definition (in the Product) is nested in another ZClass, then it is your ZClass. If the ZClass definition is defined in the top level of your product. There may be other things going on, including all of the above ;-) You'll need to provide more details to be able to say more about this. hth Rik

SiteAccess 2.0.0 beta 2
by Evan Simpson 19 Jun '00

19 Jun '00

Jacques A . Vidrine discovered a chunk of code I accidentally left where it didn't belong, which messed up the adding of SiteRoots. I've uploaded v2.0.0b2 to zope.org, but if you've already downloaded beta 1, you can fix your installation by just editing SiteRoot.py and deleting the lines of method manage_afterAdd after the call to BeforeTraverse.registerBeforeTraverse. Then you can either delete and re-add the SiteRoots, or run the upgrade script again. Cheers, Evan @ digicool & 4-am

Do you have any old copies of Zope running, that could be in the way? You should (once more) check your Zope registry key. IIRC it's CURRENT_CONTROL_SET/Services/Zope under the Parameters item (don't have an NT machine here to check). Perhaps there is some information in the relevant ZBook draft on the ZDP site http://zdp.zope.org/projects/zbook/book/VII/IntegraWebServers/IntegraWindows /ZopeIISIntegraPCGI/Drafts/954785904 (sorry for the long url, it'sprobably wrapped) >Thanks very much for your time > Oh, and one more option (and perhaps not the worst): you could try and reinstall Zope (stop service, doubleclick the Unwise.exe in your zope home and reinstal zope). In any way you'll know if it's working from a clean install. Good luck Rik
