Is there an easy way to create a copy of a folder from within a Python External Method in Zope? If so where is this documented? cheers -Ragu

I changed line 182 to read: if groups == entry.Group: and it seems to work. I still don't understand why the "in" operator does not work as expected.

If so, you will always execute the "else" at line 180, where the traceback says the error is.. Now if groups is really a string and entry.Group is not a string, that would cause the error. So you had best check to see what type of critter you are using there. Are you sure you did not mean to make use of EntryID somewhere? Cheers, Tom P

Zope does not responding
by Jaroslav Lukesh 21 Mar '03

21 Mar '03

Hi all, I was find load problem with my Zope 2.5.1 (at W2k SP3, it is terminal server). When it have many connections (*), it sometimes stops without any reason. Nothings in log, nothing written to console, Zope does not give pages and seems running (does not respond to any connection). (*) concurrent downloading of about 40 connections to render bunch of DTML pages, few minutes load for cca 2000 pages - I could reproduce this behavior with that web mirroring, but Zope sometimes (in 1-3 days) dies without my mirroring too. I was wait few minutes and zope still does not give pages, nor Control panel to make shutdown. I was kill Zope and start again and is OK. I have running Zope before for few months without any problems for one virtual web. Now I have one more virtual web. But not much load, logfile for all after week have cca 2MB =>average load 2 pages or images/sec (yes, I know about "average" dis-value). I do not use much of caching, only few, sites need to be "live". I run virtual webs via VHM and in front of is linux "pound" non-caching proxy. Pound load proxy server for cca 20% (486-100) in case of my huge mirroring. It is M$ behavior (TCP/IP stack overload?) or something totally different? I was try to use -M "logfile" option for z2.py to get detailed log, but it does not make that log. I have virtual logger patch installed - is that possible cause for missing detailed log?. Many thanks for your tips and helps ----------------------------------- Best Regards, J. Lukesh

Question about inheriting Z Classes
by Lubos Culen 21 Mar '03

21 Mar '03

Hello! I have created my own document type (Z Class) in Zope (let's call it "My document") and I'd like to implement other document's features into it (concretely, it is workflow feature from Metaflow document, but it can be anything else). I tried to do it the way I know - to create new Z Class and inherit the existing objects as Base classes into this Z Class. But I don't see this "Metaflow document" in the list between these classes (although Metaflow is properly installed and used in the Zope), so there is not possibility to inherit it as base class. Is there some possibility how to use behavior of this class in my classes or how to inherit the class other way? Thank to all for the answer! Lubos.

ZODB Transactions
by Bo M. Maryniuck 21 Mar '03

21 Mar '03

Hi, all. I have a trouble with Zope when I want to store a lot of the files into the ZODB in the loop. My ExternalMethod does something like: ---------8<-------------- for foo in session[files].keys(): fileData, fileName = session[files][foo] self.somewhere.manage_addFoo('foo', fileData) self.SQLMethod_to_mark_the_uploaded_file(fileName) ---------8<-------------- And browser waits, waits, waits, waits (not user-friendly, BTW!) and then tells me "ZODB.POSException.ConflictError" and my files was NOT uploaded AT ALL. Then I *had* only one idea to make semaphore via session. I.e.: Create a DTML Method, where is a text "Please wait" and <meta EQUIV-.../> with refresh to check the flag in the session. And my External Method does (algorhythm): 1. set a flag into the session, like: session['foo'] = '1' 2. Put the files in loop by "manage_addFoo(...)" 3. Remove the flag after the loop, like: del session['foo'] ...and then my DTML Method will see no flag and redirect to the normal page. But it does not work at all :-) Seems that ZOPE requires to roll over ZODB transaction, because even I set the flags, they does not change untill loop ends (I've checked it by the parallel process). Maybe I should somehow do the explicit commit() or so? :/ The howto here http://www.zope.org/Members/don/long_procces does not work. Have anybody at least _any_ idea (good, bad, i.e. *any*) how to do upload that <...> files? -- Regards, Bogdan Linux -- the OS for the Renaissance Man
