[Zope-dev] ZEO, FileStorage, and Undo
Hello, We have a large FileStorage database ~5 gigs. When any of our users click would the Undo tab in a management screen the request would eventually time out and our ZopeWatch script would restart the server. Well this didn't happen every time, it only happens if 20 transactions haven't occurred, or haven't occurred recently. In either of these cases the entire ZODB is searched for transactions. So I wrote a patch for undoLog in FileStorage to batch by days instead of # of transactions. This lets us show batches of 2 days at a time instead of 20 transactions. Thus we never have to search more than 2 days worth of the database. I also MonkeyPatched the manage_UndoForm in App.UndoSupport. While doing this I noticed that at the beginning of undoLog FileStorage acquires a lock (_lock_acquire). Is this necessary if it's only doing reads? We have a ZEO with 3 Zeo Clients and 1 Zeo Server when someone hits Undo the Zeo Server locks and all 3 clients sit waiting. It appears from experience as a user that_lock_acquire locks reads and writes. We have a system with potential for thousands of content maintainers. It is undesirable to have our entire site die for 20 seconds everytime one of them clicks Undo. We could disable Undos, however the transactional database was one of the reasons we choose Zope. Any suggestions? Is there a way to lock only for writes? So that pages can still be served?

[Zope-dev] WebDAV access for DTML Methods and Documents
Hello, This may be something that cannot easily be fixed, but the permission FTP Access is required for a user to have WebDAV Access to an object. Since the method is shared by FTP and WebDAV a more general permission name should be used.

[Zope-dev] ZopeTime Warp
Zope Version
(Zope 2.5.1 (source release, python 2.1, linux2), python 2.1.3, linux2)
Python Version 2.1.3
(#1, May 15 2002, 15:52:42) [GCC 2.95.4 20011002 (Debian prerelease)
I've got this script which returns strange results:
print context.ZopeTime()
print context.ZopeTime().toZone('US/East-Indiana')
print context.ZopeTime().strftime('%H:%M%p - %m/%d/%Y %Z')
print context.ZopeTime().toZone('US/East-Indiana').strftime('%H:%M%p -
%m/%d/%Y %Z')
return printed
The output from this script is:
2002/07/08 16:24:44.687 US/Eastern
2002/07/08 16:24:44.689 US/East-Indiana
17:24PM - 07/08/2002 EST
16:24PM - 07/08/2002 EST
The output of the 3rd test case is incorrect. It's as if strftime is
changing the time zone. Also the time zone is set to US/East-Indiana in
/etc/timezone, yet the default time zone for Zope Time is US/Eastern.
We do not want our users to have to manually set the time zone with the
toZone method.
Any hints?
Thanks,
-Brian

[Zope-dev] Permissions
Hello, I would like to setup the security on a Zope server such that a user can edit permissions on something they own, but not grant more permissions than what they have acquired from the parent. If a user owns a folder they could grant Owner any permissions they want inside of that folder (Assuming they have the Change permission permission). Is there a way to limit which permissions a user can change? I would like to be able to delegate permissions. Such that if a user creates a folder they can grant other roles permissions up to the permissions they have acquired from the parent folder. Is this possible? I don't want that user to be able to grant themselves additional permissions.

[Zope-dev] Zope 2.5b3 Management Tabs
I've noticed in a fresh install Zope 2.5b3 management tabs which users do not have access to view show up. In the past only management tabs that a user had permission to view the associated action showed up. Is this a known issue? or a new feature? --Brian Brinegar ECN Web Technician MSEE 104 A 494-3106 http://www.geeksoft.net/ ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] User Groups
I've found that it would be very useful to be able to define groups of users and then grant a local role to that group rather than individual users. For example we have multiple groups working together on our Zope installation and there are certian objects my group may want to share with another group. We can grant all the members of that group permission, however if they hire someone new they have to notify the maintainers of every object their group has access to. Are there plans for anything to solve this problem? The idea implementation I see would be a centralized group management system (maybe in the control panel) and then ability to grant roles to the group. But this would require changing core pieces of Zope. Any ideas on implementation? --Brian Brinegar ECN Web Technician MSEE 104 A 494-3106 http://www.geeksoft.net/ ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] PathIndex
The search method of PathIndex class returns varying types depending on the success of the search. If the search fails a list object is returned, if the search succeeds an object of type BTrees.IIBTree.IISet is returned. This causes a problem in _apply_index in PathIndex when PathIndex tries to do either a union or intersection. I am doing a search of a catalog like this: catalog.searchResults(path=['/folder1','/folder2']) This should return all objects in the catalog that are inside of folder1 or folder2 and works perfectly as long as objects from both folder1 and folder2 exist in the catalog. However if say folder2 does not exist then _apply_index tries to do a union between a list and an IISet object. This raises an invalid argument exception. I'm not 100% sure where this problem should be addressed, but a quick fix I saw was to change part of _apply_index in PathIndex from: if operator==or: set_func = union else: set_func = intersection res = None for k in record.keys: rows = self.search(k,level) res = set_func(res, rows) To something like this: if operator==or: set_func = union else: set_runc = intersection res = None for k in record.keys: rows = self.search(k,level) if rows == []: rows = None res = set_func(res,rows) This works since union and intersection will take None as an argument but not an empty list. I would suggest PathIndex.search be changed to return an empty IISet if it fails just to have consistancy.

[Zope-dev] Product Icon
I am currently working on a product which has the sole purpose of referencing other objects. One of the properties is the path to another Zope object. Then methods are defined like getObject(), getPath(). We use it as a way to manage news and events that show on several sites that opperate on our Zope server. It allows one group to add a news document in their folder and if another group would like that news item to show on their site they can create a reference to it. Anyway, what happens from time to time is an object is referencing another object when it gets deleted/renamed/moved and that breaks the reference. The product handles this gracefully, however I would like to have the icon change from our standard icon to a broken icon.

On Fri, 5 Oct 2001, marc lindahl wrote: We have schools, research groups, students, and administration that we deal with. A school may create a news document about a new professor which they would wish to display for 6 weeks. The administration offices may only wish to display the story for 1 week. The display dates for the news documents are properties of the documents. So I really need two different instances of the same property one for the school and one for the administration. However the administration probably has no permission other than View on the schools News Document so something like this would not work. We want to avoid maintaining two copies of the same story at all costs. The system I came up with was to let the administration create a reference to the schools news object where they could add their own properties or override the values of existing ones. If there is an editable record where an object could be cataloged and then the meta date for a cataloged object could be changed by the owner of the catalog it would provide the same functionality. I could just give each group a catalog and some methods of adding news to the catalog. They could then edit the meta_data in the catalog to change the display periods, priority, etc. And the display routine could use the meta_data in each groups catalog when displaying the object rather than the objects properties. Can this be done with Plugable Brains? If you have any other suggestions/hints/tips let me know. --Brian Why not use the Catalog for this? e.g. in the CMF, there's 'Topic' which does basically that.
