newbie - Zope Error

Hello all! I haven't got a clue? Why is it that some people get this error: Zope Error Zope has encountered an error while publishing this resource. Error Type: KeyError Error Value: header.gif while some don't? I get it from my office station. I don't get it from any of my LAN stations. One of my fellow colleagues get it, the other did get it too at first, then he cleared his cache and the problem were solved. (clearing cache didnn't help me or my other fellows) Tried different browswer also, with no luck!? And why did that start at all? The header.gif worked klast week without problem, and I haven't changed anything, but all of a sudden theres a definite halt? Any suggestions are helpful!

I would definietly like to hear more babout this discussion, since I'm in these thoughts too. I've done some Java but prefer Python. I had a glance at the webware project but that one weren't as well documented so I tried out Zope for starters. I've just started to wonder were the limits are, what can I do and not do with Zope? I've just started out but yes, where are the IDE? regards Stefan > On Wed, Mar 16, 2005 at 06:48:49PM +0100, Maik Jablonski wrote: > > I've done lots of web-(database)-application-stuff (not only > > CMS-things) with Zope / ZODB, but now I'm switching to J2EE / > > Oracle because it is far easier to develop and maintain a > > J2EE-application than a Zope-application. > > Hope you don't mind me butting in to satisfy my own curiosity. > Do you have prior experience with J2EE + Oracle to back this up? > -- ______________________________________________ Check out the latest SMS services @ http://www.linuxmail.org This allows you to send and receive SMS through your mailbox.

Rookie help
by Stefan Elwesthal 17 Mar '05

Hello all! Just started with Zope, since I'm a snake man myself, and so far I find it very useful and interesting indeed. I've stepped through building the ZopeZoo and the tutorial about "the King". (well, almost ;) Anyway, one thign makes me wonder? Users and access rights! In the examples, there are a guestbook application that nobody can post to since they have to login? Changing the script role as instructed didn't do any help at all. So, I created a user folder in the GuestBook application and added a user. Anyway, nobody can login as this user so that didn't help either? Could anyone point me to the right place to find out how this things are supposed to work? I feel I'm missing something vital here..

Re: [Zope] Database not in sync for days ?
by Serge Renfer 16 Mar '05

Thank you Paul for your speed answer! From what you tell me it sounds like I have a problem with packing! And that could be effectively! I use this command on crontab: 40 4 * * 6 /usr/local/bin/curl -u clean:database http://localhost:8080/Control_Panel/Database/main/manage where "clean" is a user I created for this operation only, with "database" as password. It didn't pass, because of security settings => I set local roles with Control_Panel/Database/manage_setLocalRoles and gave "clean" the "manager" role => it worked OK manually, but with the cron stuff it didn't pass (I must have done something wrong!) But the thing is that a "pack" command was sent by cron, eventhough it didn't pass (I got some mail from the system telling me that I didn't have the rights to do that command) Could it be that, for some reason the "packing process" had been initiated, although it could not go through => locking the Data.fs file and writing to the Data.fs.tmp file ? That could explain the problem we have! By the way, which is the best way to initiate a packing automatically? I have seen the "zeopack" script in 2.7.4, but I guess it wouldn't work with zope without zeo, would it?

slow python scripts
by Tim Morgan 16 Mar '05

16 Mar '05

Our agency just switched from Plone 1 with Zope 2.6.1 to Plone 2.0.5 and whatever Zope comes bundled with their installer (2.7 I guess). An application that ran pretty well on the old Zope now runs dog slow on the new one. I narrowed it down to Python scripts that are being called repeatedly in a loop. The activity of the scripts isn't very slow, but just to make sure, I moved all the code out and had them simply return a string. Still, each call to the Python script is considerably slower than it was with the old Zope. >From my reading, there are some new security checks being done with each call to the script. Is this correct? In any case, I need some options for how I can speed this up. Is there some less-secure Python script product I can install for just this purpose?

Hardware Platforms

Greetings All, Currently we have been testing Zope 2.7.4 on Solaris 9. We plan to link Zope to an MS SQL 2000 database as part of an existing process. The issues we have been having is that we can not seem to get the system to handle more then 50 concurrent connections. We have established this is more a problem with the database connector then a problem with Zope. I was wondering if anyone out there was using Solaris and MS SQL, and if so what drivers are you using?? I would also appreciate any other OS/database recommendations for anyone who is running a high traffic website/database backend. We need a system that at a minimum can handle 100 concurrent connections, and it doesnt seem like Zope on Solaris is the answer to this. We have tried to compile some db connector for access to MySQL and the Solaris server has not been very helpful. Thank you for any all recommendations! Jay

Help interpreting traceback? ZODB Couldn't load state
by Jean Jordaan 16 Mar '05

16 Mar '05

Hi all A couple of objects in our one ZODB are acting up. This is what I see when I try to browse to a page which lists Query instances: Unauthorized: The container has no security assertions. Access to 'id' of (Query instance at 40596140) denied. Some of them are OK, three of them aren't. When I see the above in the browser, I see the following in the log: 2005-03-15T09:56:19 ERROR(200) ZODB Couldn't load state for 0x03ad7e Traceback (most recent call last): File "/home/upfront/Zope-2.7.3-0/lib/python/ZODB/Connection.py", line 600, in setstate self._set_ghost_state(obj, p) File "/home/upfront/Zope-2.7.3-0/lib/python/ZODB/Connection.py", line 639, in _set_ghost_state state = unpickler.load() AttributeError: 'bool' object has no attribute '__dict__' That's repeated 18 times, for 3 different ids. The following test script finds 3 paths, but there's something wrong with the returned objects. For example, they don't have ids! obj.getId() acquires the container's id. for p in context.Catalog(meta_type='Query'): try: obj = p.getObject() x = obj.id except: r.append( p.getObject() ) -- Jean Jordaan http://www.upfrontsystems.co.za

Database not in sync for days ?
by Renfer Serge (EDU) 16 Mar '05

16 Mar '05

Hello, I had that same problem a month ago: a Zope 7.4 instance turning on a Solaris 9 with a 2.7 Gb Data.fs file, (hypo.ge.ch:8080 is for schools of secondary degrees in Geneva, I introduced zope there a few years ago and it meets a great success among teachers and schools but our base starts to grow big and we are encountering big problems to manage it with very little resources !) On saturday evening there has been a failure that required my intervention, I stopped zope and tried out the fsrecover script. Everything went OK and there had been no error found by fsrecover (?). I restarted Zope removing the Data.fs.index (I noticed that often Zope wouldn't start because of discreapencies between Data.fs and Data.fs.index => I wonder if it is not ZSync that does that mess?) It restarted OK, but all that has been made for 2 weeks was gone !!! Loking at the log to find out why, I saw in the event.log a lot of ERRORs of that kind: 2005-03-11T23:08:04 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 213.3.93.136:189 89 at 0x77bf828 channel#: 167268 requests:> (socket.error:(11, 'Resource temporarily unavailable') [/usr/local/lib/python2.3/asynchat.py|handle_ read|88] [/prd/data/Zope/var/zope2.7.4/lib/python/ZServer/medusa/http_server.py|recv| 423] [/usr/local/lib/python2.3/asyncore.py|recv|356]) Does anyone know, what does that mean and could it be the problem I have in this configuration? Dieter Mauer told me that after each transaction zope writes into the Data.fs, how can it be that I have a base with 2 weeks of missing data from the moment I do a restart? Thank you for your help, folks, I get despaired with that problem (many teachers lose hours of their work) serge

passing positional paramaters
by Ivan Stout 16 Mar '05

16 Mar '05

Greetings. I am trying to create an open source communal translation zope product thingy and have run into a snag. I had everything working, but then I realized that I needed to distinguish between what the language that the original document bein translated was in, which required passing an additional paramater to my query to gadfly. Well, this supposedly "broke the paramater chain" requiring me to explicitly add positional paramaters. The problem is, though I no longer get an error, no results are returned from my table. The paramaters are filtering the query, so I believe that my values are getting altered in some way that is causing them to not match anything. Here is what I suspect is causing me trouble . . .(the "----------------->" part): <dtml-var name><br> <dtml-var doclang> <form action="parsegettranslation.py" method="get"> -----------> <dtml-in expr="gettransdoc(_.None,_,name='name',doclang='doclang')"> <br> <dtml-var ordering> <dtml-var content> <br> Thanks!
