RE: [Zope-dev] How should an ideal Zope IDE look like?

I agree with Andre. The feature list is ambitious, but complete. That's pretty much what I was about to write myself, but he beat me to it :) More important is the second point: Having such a tool would bring a HUGE amount of value added to Zope. Mega, super huge. In fact I was once presented with an OO CMS much like Zope, but commercial, where the IDE/Management interface was much like this ... That alone was worh the 50K price tag ... Want to load a document ? Click -> Drag -> Done. That simple. My main concern would be it's adaptibility to custom content types. If I have my own Geospatial-ish content type, how would the IDE handle it ? How would I go about making it handle it ? etc ... In some respects I thnk such a project would be best "hosted" with Zope itself, since to make it work really well you may need to do work real close to the core of Zope. Also, as mentionned given the immense value added to the product, I'm thinking ZC would benefit greatly from it and should maybe be involved ? Basically, yo me this should be a core feature of Zope, not an add-on.

It was not my expectation that you would go and implement all of this ;-) Of course, this is a lot of work, but much has been done by others, already.

RFC: Multi-Databases
by Jim Fulton 06 May '04

06 May '04

I've written a proposal for adding a feature to ZODB to make it easier for applications to use multiple databases together: http://zope.org/Wikis/ZODB/MultiDatabases This is needed in the short term to fix the current breakage of Zope mounts in a sane way. In the long term, this will allow is to *finally* support cross database references. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

getRoles()
by Erik Myllymaki 05 May '04

05 May '04

I was fooling around in AccessControl\User.py, tying to add some user groups from an NT domain in the getRoles() method. Why does the getRoles() method get called so many times? Seems like once for each object on a page that needs authentication? Was making for a VERY slow page load while my NT Domain was across a slow WAN link. I would have thought it would have been called once and then cached, or...? thanks for any insight.

zLOG changes
by Andreas Jung 05 May '04

05 May '04

Hi Fred, there are currently two things confusing me: - the entries in the event.log are currently written without the log level. Is this dedicated behaviour? I think the log level should be part of the event.log - when adding LOG = getLogger(...) LOG.info(...) to some modules then the output is only written to the event.log but no longer to stdout (if running in debug mode). Is this change intentional? Andreas

Zope 2.X Session problems
by Kris Erickson 05 May '04

05 May '04

Per this thread that seems to have been dropped (MaxTransientObjectsExceeded Error); I have been having a similar situation--i'm wondering if it's a situation in which a for loop is getting passed null values to set into session? Example: form = {} for k,v in request.form.items(): form[k] = v session['form'] = form # Assuming that there *is* a form... and if not, is that the MaxTrans error? Anyone with any ideas on this? Thanks, kris

It gives you a POSKeyError, when this is not the case. This sounds like what I'm looking for. Does it work something like the following? 1. Enter date at a particular place 2. Cookie is set 3. You can browse whereever you like at it will be exactly as it was Is it possible to have a look at the code? > >Also, is there an alternative to compacting the ZODB such that all that > >history could be archive offline but then reconnected when needed for view a > >snapshot? Does anyone have an idea of how hard this would be to do? Basically what I'm proposing is 1. Ability to mount two or more databases, each of which is the same DB just at a different slice of time e.g. 1 week 2. Ability to slice a DB in half. The back half is essentially rolled back and the front half is compacted so when joined they have the complete history. This way if they wanted to view diffs of pages or the whole site at a particular date then they just have use some admin interface to mount the right time period from backup storage and then just use your tool above or normal zope diffing. I think such a feature would be a real asset to zope in the corporate/government environment Dylan Jay --- http://www.meetmemap.com - makes giving directions easy http://www.pretaweb.com - Update-it-yourself, low cost websites http://www.eatmanifesto.com - against all dumbing down of food http://www.subjectivise.com/StockPhotography

masimum number of mounted databases with APE?

Hi, I am thinking of partitioning my ZODB quite a lot for both serving and packing performance reasons. What is the maximum number of recommended mounted ZODB's to use with DBTab?

patch for #1074
by Jamie Heilman 01 May '04

01 May '04

As per usual the collector won't let me attach patches to issues I didn't start, so here's the patch for some issues discussed surrounding 1074. Now there are some caveats to this patch... I haven't protected every method, left to do yet are: manage_FTPget, get_size/getSize Also note this patch removes dependance on MessageDialog - that really had no bearing on the issue at hand and I only include that portion of the patch because in my fork I removed all reliance upon MessageDialog (a class I really loathed) and I'm too lazy to add it back for the purposes of this patch. -- Jamie Heilman http://audible.transient.net/~jamie/ "You came all this way, without saying squat, and now you're trying to tell me a '56 Chevy can beat a '47 Buick in a dead quarter mile?

+1 Great idea. When ZCatalog is used with very big site any small changes rebuild index and Data.fs growth incontrollabe. If we can use other storage to store some objects (ZCatalog) it will be more easy support thouse sites. -- Mikhail Kashkin "Key Solutions" (http://www.keysolutions.ru/)
