Actually the more I think about it, this suggestion of inheritated roles would vastly simplify the roles I use on my site and make it a lot more logical. Is this something that is a planned extension? If so, is it easy to do (and hence possible for me to patch)?

That would be useful in otherways. What your talking about would be like inhertitance of roles I think, which would be very useful. It would make it somewhat easier to do what I propose since then you could make up a role for each restricted area and then just include the roles that are allowed in. But it still doesn't help in other areas. For instance I have a sitemap that is generated dynamically from the zope ODB. I don't want to include links in there that the user can't see. > With this approach the notion of role becomes much more like > a notion of > groups. > > >  > >  > >  > > At first glance exposing this stuff at this level would be pretty > difficult since different objects can have different permissions > associated with them. Can't a permission be looked up based its string label?

Patent Threat to Zope?
by �̰��(LEE Kwan Soo) 27 May '99

27 May '99

Just read from slashdot. A company filed & granted a patent which may become a threat to our cherished Zope('s potential, at least). Excerpt: "When the browser makes the request to a Web server, the patent covers the notion of redirecting that request to other machines [application servers] within a cluster and having those other machines dynamically produce a response," Wired. See this link. What do you think of? LEE Kwan Soo.

RE: Using supplied demo Gadfly database
by Aaron Watters 26 May '99

Olivier Berger reports: >I found the demo (empty) database supplied with Zope but couldn't get it to work... >even a simple select * from __table_names__ won't work... >Tried to import an allready working gadfly base created with Python (gfplus) next to the >demo directory, but neither did it work.... I think this is because Zope distributes a very old version of Gadfly and probably uses it even if you have the 1.0 released version. Maybe try hacking whatever zope uses for the pythonpath so that it gets the released version. Beyond that I'm clueless.

(The RPM may work, but you'll need the devel RPM *and* the bin RPM will need to support threads. This was not so in RedHat 5.2, so you either had to compile your own or use the python that came with Zope). So get 1.5.2, compile --with-threads and install. Your on your own here. Download 2.0.0a1, untar and unzip. run 'python1.5.2 wo_pcgi.py' if it fails at this point it's probably because it couldn't compile the extensions because 1.5.2 was not installed correctly. Your on your own. customize ZServer file 'start.py' (you'll need to read it and grok) start up ZServer and go with it. -Michel > Thank you for your attention, > > Michael Bernstein. > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

ZODB and large data sets
by Jimmie Houchin 26 May '99

26 May '99

I am working through the design of my website as I study and learn Zope. I've started to work on calculating storage requirements to determine server needs as I am also working on building my server. My app can easily be divided into multiple datasets or databases. One of the datasets I am looking at has a potential of 4+ million objects with each object requiring 15-50kb minimum. This dataset can be subdivided. Initially I will not populate the database will all of the items in their full form, but will populate as requests for data come. However I need to develop as if and plan for complete population. This makes for a very large database and one that spans more than one hard drive. Can Zope create and use multiple ZODBs on multiple hard drives? If so, how will such a large dataset affect packing and the creation of the backup file? Will I need to use multiple other database backends such as MySQL or possibly MetaKit? Thanks for any help or thoughts. Jimmie Houchin
