[Zope-dev] property type
According to docs and testing (in the interpreter) I can make a read-only calculated attribute using property() (I know that setters do not work w/ non-new-style classes). So I tried the following: class CMixin: def getter(self): return 'test' prop = property(getter) and when I try to mix in this object w/ a Folder object, the instance returns property object at 0x8b45edc for the 'prop' attribute. Is this an issue with pickling or something else? Cheers, Tim -- Tim McLaughlin Chief Technology Officer Siteworx, Inc...

[Zope-dev] Unsynced ZEO Clients and Undo
Hello, We've run into a problem with Zope 2.5.1 and ZEO 1 where a user does an Undo and some of the ZEO clients reflect the change and others do not. I believe it has to do with caches getting out of sync. Is this a known problem? It has happened to us at least 4 times that I know of. Usually we will restart all of the clients and remove the caches, to fix the problem, but this is not desirable.

[Zope-dev] Making private documents viewable by members in CMF
CMF comes with a default workflow with three states: private, pending, and published. When an object is in the private state, only the user who created it and site managers can view and change it. How do I change the roles or security to allow Members to view each others private documents without making them managers?

Re: [Zope-dev] Making private documents viewable by members in CMF
(Untested but should work) Make your own workflow with DCWorkflow (search and install that CMF extra product) DC Workflow comes with a pre-built workflow that acts like the CMF default workflow Edit the private state of the workflow in the permissions tab. Grant the View permission to Members. Associate this workflow to the appropriate content types.

[Zope-dev] override __of__
Is there any way to override __of__ on an object? I've tried it but for whatever reason, Implicit.__of__(self, object) says that self is not an Acquirer even though the object is a subclass of Implicit. I would implement in a traverse hook, but attribute access of that object won't do traversal. :( Cheers, Tim -- Tim McLaughlin Chief Technology Officer Siteworx, Inc...

[Zope-dev] RE: [Zope] Time module in python scripts
I hope you all don't mind, but I've moved this to Zope-dev. I would like to propose that it be possible without modification (default behavior) in a future version of Zope to import the time module and its methods safely into TTW Python Scripts. I haven't used this yet in TTW code (I've had to work around it), but it seems like it might be good to un-restrict it, especially for CMF installations that heavily utilize date metadata. time.localtime(time.time()) is, AFAICT, the only way to determine if you are in standard or DST at any point in time during the year. You can't have a page-template appropriately display correct times for content from multiple time-zones without this (I'm sure many CMF installations will need this), and it seems silly to write an external method for this; allowing import of the time module is a good workaround, but I would suggest it be enabled by default in Zope. My particular use-case is AP newswire stories which are in EST/EDT. The timezone offset changes for this twice a year, and having a fixed calculation based upon some assumption of a fixed timezone offset in my own timezone (PST/PDT) won't work. I need to be able to know my own timezone offset to do the math, and for this I need to use time.localtime(time.time())[8] to get it. I'm sure community sites and things like blogs, or anything else that works across the geographic boundaries of differing time zones could use this too. Thoughts?

Re: [Zope-dev] RE: [Zope] Time module in python scripts
Hi I wonder why DateTime().parts() results is different to time.localtime(time.time()) or at least returns less info than the latter. It would seem a change to DateTime would be in order ?

[Zope-dev] What makes Zope twirl?
Or: when zope goes into a nonresponsive state, what can you do to diagnose the cause? The even that prompts this question: Our production system (2 zeo clients) went down today. Platform: Linux 2.4, Zope 2.5.1 from source (wo_pcgi), Python 2.1.3 from source, running behind Apache for one site, and a custom java proxy for another site (don't ask). ZServer is not exposed to anything except the servers running Apache and the Java proxy. All the zope processes were still running, CPU usage was low (almost nil for python), * there was plenty of free physical memory swap. Yet Zope was not responding to requests. A look at the access logs revealed that zope had not logged anything since the time we noticed the outage. Nothing unusual before that except AltaVista crawling our site (a measly 2 requests / second). A restart seemed to fix everything, though one of the zeo servers went down again (same symptoms) about 20 minutes after starting. Restarted it again and both servers have been fine for hours now. This seems to be rare; I haven't seen it before on this particular server, but I saw a similar wedge on our dev machine about 3 weeks ago. I've looked at ALL the logs (access log, zeo log, zope stdout / stderr log) and found nothing at all unusual, just the aforementioned AltaVista crawl and a couple of RAM Cache errors from non-pickleable objects that I need to dis-associate from the cache. But none of this is new. Is it time for Big M? WOuld that give me anything useful? * this does not sound like other zope spins I have heard of, in which python eats 99% CPU indefinitely due to (probably) an application error. see for example: http://www.zopezen.org/Members/zopista/News_Item.2003-01-28.1025 -- Paul Winkler http://www.slinkp.com Look!

[Zope-dev] Zope Server Control
Zope-Dev'ers, Just for fun, I made a mockup (using QT Designer) of a Zope server control and monitoring GUI. It's purely nonfunctional--just an idea. Check it out here: http://hathaway.freezope.org/Images/controller_snapshot.png It's not fancy, but it's complete: you can watch and control multiple servers from a single place. The flashing yellow LED-like indicators would give you a great deal of confidence that information is flowing. It sure would be appealing.
