[Zope-dev] Quixote PTL
Is anyone using Quixote's PTL? http://www.mems-exchange.org/exchange/software/python/quixote/ It looks like it might be useful in the niche that involves too much logic for DTML, and too much joining-strings-together to make python (or PythonMethods) cumbersome.

Re: [Zope-dev] ZODB optimization
[EMAIL PROTECTED] wrote: I'm wondering, is the ZODB easily 'fragmented' or .. un-optimized ? If so, are there any tools/functions that will 'unfragment' / optimize it? This really depends on the undelying storage used. Does the 'pack database' in the Administration menu do this? Packing does two things: - It removed records for objects that are no longer referenced (as of the pack time), or, IOW, it doesm garbage collection. - For storages that support undo (and time travel), it also removes records that were not current as of the pack time. Both of these, especially the latter are a little bit similar to defragmentation or optimization. In addition, the particular storage implementation may have other issues/tools. For example, if the Oracle storage is used, them whatever fragmentation or optimization issues or adminstration tools provided by Oracle apply. If so, it could be a Good Thing (tm) to have separate optimize and packing (history deletion etc.) functions (buttons). This doesn't really apply. Is there any way to make an object not keep history on itself or on contained objects ? Currently, the only way to do this is with a non-versioning storage, such as the Berkely DB storage.

[Zope-dev] Workflow, Python and Zope
Here I just repost a statement from Michael ([EMAIL PROTECTED]) concerning his workflow product (http://www.vivtek.com/wftk.html, Open-source workflow toolkit). Maybe it's useful for some further developments. Best regards Arno Gross, [EMAIL PROTECTED] Re: Workflow, Python and Zope Posted By: Michael [EMAIL PROTECTED] Date: Tuesday, 19 September 2000, at 10:08 p.m. In Response To: Workflow, Python and Zope (Arno Gross) As Josh already mentioned there is Zope and Python. Currently there is a discussion thread in the Zope mailing list (http://lists.zope.org/pipermail/zope-dev) and in egroups: http://www.egroups.com/messagesearch/zope?query=Workflow, discussing Generic Workflow. I am convinced that it would be a great shift to build a Workflow product on Zope with Python. There is already a small basis of a workflow, but maybe we could pull together the resources. Arno Gross [EMAIL PROTECTED] Actually, I'm currently learning Python. As Python is typically extended with plain-vanilla C modules, and as the new and improved wftk (which hasn't hit stores yet) is reimplemented as a set of libraries, I think that it's going to be really simple to drop the engine into Python and Zope. That'll be my next trick.

At the time that standard_html_* were introducted, DTML was used soley for creating templates to display content in Python objects. The expansion for DTML is Document *Template* Markup Language. The mistake was not introducing components, but introducing the use of DTML as content. Jim -- Jim Fulton mailto:[EMAIL PROTECTED] Python Powered!

[Zope-dev] ZDebug Issues... Round II ;-)

ZDebug doesn't have a way to figure out what DTML method is being called in Zope 2.1.6. Strange but true. So it shows what it can. The 2.2.x security context stack is used to figure it out in 2.2.x.

[Zope-dev] acl_users

A quick search of the Zope source turns up only 9 references to 'acl_users', found in only 4 source files. dtml-snip brevity Personally, I think it's an intriguing idea, as I have had more than one application where I would rather have called a LoginManager by some name other than 'acl_users'. But I'm not sure it would be worth the work. One of the ideas I am kicking around is that of CommunityMembershipSystem. In Membership-CMS, a user folder owuld need to be made, to house the user's objects. Now, there are a few ways of doing this...here are two: 1) Have the install method add a folder to do this with 2) Have the objects stored in the user object. Both have their ups and downs. For example, (2) would not deperate UID from URL's too cleanly; though it would be easier to implement in short order. Meanwhile, (1) requires the install method be given more information (where to put the folder?), and could be trickier to debug. In (2), the url to the member's folder would be "/Members/username" instead of /acl_users/username", provided the userfolder could be named something else. I don't see a reason off hand for a UserFolder to be renamable. Another reason I have considered it, is that it lends a _weak_ amount of security-through-obscurity. For example, if you see the following in a URL ".../acl_users/loginForm", you know that the site is running Zope, and where the authorization takes place. I dunno if I like it being _that_ obvious. -- E PLURIBUS LINUX ___ 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 )
