Incidently, I've just added some print statements to trace the Zope startup, and "Five" is by far the slowest product to load, taking about 3 seconds. Running up is PlacelessTranslationService at around 1.5 seconds (And much less if I kill all .po files). -James.

FastCGI server crashing

I am experiencing seemingly random crashes of the Zope FastCgi server that are really annoying users. Any help most appreciated. Apache errors: FastCGI: comm with server "/space/apache2/fcgi-bin/zope.cgi" aborted: idle timeout (30 sec) FastCGI: incomplete headers (0 bytes) received from server "/space/apache2/fcgi-bin/zope.cgi" Zope error: 2006-08-07T11:17:36 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.FCGIServer.FCGIChannel connected 127.0.0.1:43792 at 0x43c13e2c> (socket.error:(32, 'Broken pipe') [/usr/local/python235/lib/python2.3/asynchat.py|initiate_send|218] [/usr/local/python235/lib/python2.3/asyncore.py|send|337]) System: Redhat 7.3 Apache 2.0.52 mod_fastcgi 2.4.4 Python 2.3.5 Zope 2.7.8 Thanks!

Moments ago I wrote this: http://www.fry-it.com/at/refresh-production-zopes which I think is a brilliant solution to updating product/live Zope instances without downtiming the server and losing SESSION variables for users on the site during the restart. Product refreshing is important for me for my future in Zope land. Because I depend on product refreshing so much it means I can't dip into Zope 2.9. Apparently the "bug" is somewhere deep in the ZODB code (thanks Dieter Maurer for pointing this out some time ago) and that's a domain I'm very very novice in debugging.

Renamed user account and OpenFlow
by Tit-Liviu Leontin 07 Aug '06

07 Aug '06

Hello everyone, I'm currently taking over the administration of a running instance of Zope and OpenFlow. These have been used to create a workflow for a decision making process. The users are authenticated via LDAP. The problem is, one of the workflow users got married and the username has been changed to reflect the new last name. Instances already in the workflow are assigned to the old username, and the person cannot log in to interact with them. I can assign the new username to the correct role, but what about the old instances? Is there an easy way of migrating the instances assigned to the old username to the new one, or maybe creating a local user with the old username? Any step-by-step suggestion is welcome, as I'm barely getting familiar with the admin interface. Thanks in advance, Titel

Yes, but it's still very handy and many people have come to rely on it. You might blame Plone for shipping for three tons of frameworks? I'd agree with you there- theres a little too much bloat, but theres not much that can be done about it at this point without a major architecture update. I understand and fully agree with you but things are as they are. Even > worser....Refresh does not work Five... How come? Is there a major technical reason why it CANT work, or is it something thats just broken and needs fixing. I'm happy to do the fixing if it comes to that, I just need someone to point me in the right direction. Refresh only works in debug-mode. You want to tell us that you are running > a production site in debug-mode? No. I've never had a problem refreshing in production mode.... ? > Dieter Maurer wrote a RefreshTool product lately (not sure if this would > solve your problem and not sure if he released it). I'll have a look- thanks. > I doubt that the Refresh situation will change in the near future. As above- is this a major technical problem with Zope 2.9 or Five, or just something that no-one is really bothered to fix? Thanks, James.

Providing Arguments to ZSQL Methods that Insert and Update in Python
by Muk Yan 06 Aug '06

06 Aug '06

Dear Zenith of Zope Knowledge, Thanks for all the help from before it is truly appreciated. I know that it's possible to provide arguments when selecing in a ZSQL Method, but is it possible to provide arguments to UPDATE and INSERT. I'll use an example that I found from a previous entry in the Zope mailing list. The ZSQL method looks like this: Arguments: emp_id first last salary UPDATE person SET person_first_name = first, person_last_name = last, person_salary = salary WHERE person_emp_id = emp_id and the call in the Script(Python) would be: (context.aq_parent).updates.update_person(empid=someval1, first=someval2, last=someval3, salary=someval4) I'm having trouble correlating the Python variables with the ones in the ZSQL method. I know how to pass variables from forms in DTML documents via <dtml-sqlvar emp_id type=string>. Any help would be appreciated. Thanks in advance and have a great weekend! Take care, Muk Yan

SERVER CRASHED! VHM/Apache2 Arrrgghh!!!
by beno 05 Aug '06

05 Aug '06

Help! Second day server's been down!! I tried to upgrade from apache 1.3.3 to 2.2.3 and now nothing works. Can't remember or find anything I changed on the old apache but that won't come up either. The problem is in proxying. I use VHM. I had to comment out the following lines in order to get Apache2 to come up: # Reverse proxy params CacheRoot "/tmp/proxy/shop.2012.vi" # CacheSize 100000 # CacheGcInterval 2 # CacheLastModifiedFactor 0.1 # CacheDefaultExpire 1 # CacheDirLength 2 Of course, then nothing in Zope works, because it's all based on VHM! I've been googling my brains out with no luck! Did the cache rules get rewritten in Apache2? Is there new syntax I should use? Here's my configure command: ./configure --enable-so --enable-expires --enable-vqadmin --enable-speling --enable-rewrite --enable-cache --enable-deflate --enable-disk-cache --enable-mime-magic --enable-mods-shared="proxy proxy_http proxy_ftp proxy_connect headers" Please help. This is my FOURTH POST, second to Zope, and NOBODY has responded to the first three!!!!! TIA, beno

I had a quick look at the dtml tree doc (i have never used it, so am just going on what i read), but it seems that you can specify methods that are called in order to obtain branch elements and there is an attribute 'expr' which allows you to provide an 'expression' which provides the value to be displayed, so it sounds as if you should be able to write your own routines to pull the info out of your db.

adding product-based objects programmatically
by Kees de Brabander 05 Aug '06

05 Aug '06

Hi, Apparently my knowledge of Zope/Python is still to limited. I have a product that derives from Folder. When I add this product to a folder via zmi I want to have it populated with other products to it programmatically. I tried to do so in the __init__ function. That works with objects like acl_user folders, but not with products in the products directory. Can anyone send me in the right direction or at least give a hint where to look for a solution? With trial and error I came thus far (stripped down to the basics): Module QuerySet.py: from Query import manage_addQuery class QuerySet(Folder): def __init__(self, id, title): self.id = id self.title = title self.manage_addUserFolder() manage_addQuery(self, id, title) manage_addQuery in Query.py looks like: def manage_addQuery(dispatcher, id, title, REQUEST=None): "...." nQ=Query(id,title) dispatcher.Destination()._setObject(id, nQ) if REQUEST is not None: dispatcher.manage_main(dispatcher, REQUEST) Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Products.QuerySet.QuerySet, line 80, in manage_addQuerySet Module Products.QuerySet.QuerySet, line 107, in __init__ Module Products.Query.Query, line 80, in manage_addQuery AttributeError: Destination zope 2.7.8, win32 tia, cb
