If people like to use them, let them! It's not up to you to decide for THEM what's best or not. The choice for YOURSELF not to use them is just as fair as other peoples choices. martijn.

[PATCH] to Zope's Management Interface
by Jerome Alet 08 May '02

08 May '02

Hi the attached patch to apply to zope/lib/python/OFS/dtml/main.dtml allows people who want to use ZShell to type ZShell commands directly from the Zope's Management Interface. It should be transparent for people who don't want to use ZShell at all. to use this patch, you have to : - download ZShell v1.42 from : http://www.librelogiciel.com/software/ This is mandatory to stay in the ZMI when running commands, otherwise, with older ZShell versions you'll enter ZShell user interface after entering a command. - extract it in your home directory - cd to the Zope's home, e.g. /usr/lib/zope - type the following command (as root) : patch -p0 <~myusername/zshell-1.42/main.dtml.patch - restart Zope Enjoy !!! (At least you should) This was tested against Zope 2.5.0-4 (Debian package) but applying the patch manually to other versions if needed is very easy. As always any comment is very welcome. PS : This procedure and the patch are now included in the ZShell 1.42 package.

updateObjectList for objectManagers?
by Lennart Regebro 30 Apr '02

30 Apr '02

I have had a couple of problems with an object managers self._objects getting out of sync with "reality", so that it keeps the wrong names or the wrong meta_types in the _objects list. Is there an "update" function that you could call to make it scrap this list and rebuild it? It would be nice I think...

ZSQLCatalog
by Jean-Paul Smets 29 Apr '02

29 Apr '02

Philippe Beaumont (mostly) and I just finished a product called ZSQLCatalog. It allows to query the Zope Catalog with SQL methods and find objects in the ZODB with complex queries in SQL. http://www.zope.org/Members/nexedi/ZSQLCatalog It is still a proof of concept but should improve a lot and very quickly. Suggestions are welcome. JPS. -- Jean-Paul Smets-Solanes <jp(a)nexedi.com> - Nexedi (CEO) GPG Fingerprint: 40FF FA78 75AA 680D 8BB4 EEF9 539A 79CC CB8E 5F01

Fair enough, I hadn't considered the time trade-off due to the reverse index being loaded. However, let me couch my suggestion in a different way. We've identified that the metadata can be located in possibly 3 different places. Use of each has different speed/space trade-offs. Using each also has a different API eg (from memory so won't be entirely correct) getObjectForRID[object_id_].field getIndexDataForRID[object_id_].field field All these methods might result in the correct data being displayed for a given search (each with a different tradeoff). Perhaps there should be a way of making this tradeoff transparently. That way the report designer can be ignorant of any optimizations eg <dtml-in Catalog> <dtml-var title> </dtml-in> would work no matter whether the title was set as metadata field or not. If it wasn't then the catalog might access the object and look it up (with the resulting time penelty). Then, in the same way as in the RDBMS world, the indexs (the Catalog) could be adjusted to make this operation more efficient without changing any code (just add metadata to the Catalog). The same tradeoff could be used if an admin decided that the object was too big and overhead of repeating the field in metadata was too big, then they could decide to obtain the data from the FieldIndex data instead.
