How do I install a database adapter

I downloaded the SQLite database adapter. There are no directions. What do I do to install it? Bob Gailer bgailer(a)alum.rpi.edu 303 442 2625 --- Outgoing mail is certified Virus Free.

Ownership & permissions of var for Zope on port 80: Definitive answer?
by Ian Beatty 26 Sep '03

26 Sep '03

Greetings. I'm going crazy trying to figure this one out. What I want is pretty simple: to have Zope (2.6.1, python 2.1.3) run on port 80 on a Red Hat 8 system. That's got to be pretty common, right? I've got a startup script which runs as root, and launches Zope with the -u flag to change the process owner to a user named 'zope'. Problem is, I can't figure out how to set the ownership and permissions of the var directory to get everything to work properly. I've tried setting everything as instructed in doc/SETUID.txt, but that doesn't work for me. I've also found conflicting information in the archives of this list and in other Zope docs. Basically, I get one of two problems: 1) If I set the owner of var and its contents to root, Zope launches just fine, but if I try to pack the database through the ZMI, I get permission-denied errors. My Plone site managers also start getting weird permission-denied errors after a while, too. 2) If I set the owner of var and its contents to the Zope user 'zope', Zope silently fails on launch. If, however, I let Zope launch with root owning var and then, after it's running, change the owner to 'zope', everything works just fine. Until the next time Zope needs to restart, when it silently fails. Ugh. I've tried setting var's owner to root and group to zope (the group that the zope user belongs to), with g+w permission to var and its contents, but then I still get permission-denied and 'Operation not permitted' errors when packing the ODB. I've done chmod o+t and chmod a+s, neither of which seem to have helped much. (I don't really understand what they do, but one was indicated in SETUID.txt, and the other somewhere else on zope.org or someplace like that.) Please, there's *got* to be a definitive answer on how to set up a linux system for running Zope on privileged ports. Can someone post or point me to it?

Thank you for you thorough critic of this method. I like zpt, the idea of having presentation logic in template and business logic in a script makes a lot of sense to me. However, I am only now begining to get my head around python and the zopish way of doing things. Please clarify your comments below. > > > setattr(myClass, 'Content_Main', Content_Main) > > eep!

It is defined in a module which is then imported into each module that needs it. Is there an issue I should be aware of? > You can't really.

RE: z2 startup exception, only with -D?
by Arenz, Ralph 26 Sep '03

26 Sep '03

I think in rolling off the whole procedure. 1)Downloading new Zope-2.6.2-src compiling starting without Instance_Home -> everything fine 2)Restore a root.fs-backup in the Instance_Home. starting in Instance_Home (with the whole args incl. -D) -> startup-Exception 3)Get rid of all args in the start-command starting in Instance_Home -> Zope cames up -> in the log the "Module not found" seems to change its result from an z2-Exection to a ERROR(200) 4)Successively i added my arguments and looked for the startup behaviour. The "-D" lets the startup end in an "z2 Startup exception". Putting -D out of the args -> startup-Exception 5)By following the zope startup-source to figure out the why i completely lost my nerves. In my humble opionon the -D option is responsible for the crash, but why, i don't know ... Ralph sorry, i suppose you have not followed the whole thread because i make a mistake by posting to the right one in the middle of the discussion :-( I try to outline what i've done until yet. My intension was to upgrade Zope-2.4.2 to Zope-2.6.2. I installed the Zope-2.6.2-src compiled it and started it without Instance_Home. Anything was fine until i tried to to use 2.6.2 with Instance_Home. I got the z2-startup-exception. (Module Splitter not found) -> although it is there! First i tought that something with the root.fs is wrong so In mind that i was succesful in starting Zope in that Configuartion i unpacked an backup of an earlier root.fs played around in the start-script in Instance_Home. Beginning with no args in the startline,successively i added my arguments and looked for the startup behaviour. Reaching "-D" lets the startup end in an "z2 Startup exception". -----Originalnachricht----- Von: Chris Withers An: Arenz, Ralph Cc: 'Jamie Heilman'; 'zope(a)zope.org' Gesendet: 25.09.2003 15:07 Betreff: z2 startup exception, only with -D?

If that's the only difference, then yes, very... How have you checked that the removal of the -D was the only change? Chris

I'm testing the new sitemap method http://zope.org/Members/mwr/python_zpt_sitemap_zen and I get the following error: "You are not allowed to access aq_explicit in this context" I'm logged in as a manager. Where in ZMI can I allow aq_explicit? -- Milos Prudek

SQLite database adapter
by Bob Gailer 26 Sep '03

26 Sep '03

After trashing around and making a bunch of guesses I put a folder called ZSQLiteDA into the E:\Program Files\WebSite\lib\python\Products\ directory and now ZOPE startup recognizes the folder and attempts to load the product. It failed with ImportError: No module named sqlite. I tried putting the sqlite folder in the products directory, then the ZSQLiteDA directory. Now it fails with ImportError: No module named _sqlite. I have run out of ideas. What should I do? Is there some place that explains how all this is supposed to work, or are we all on our own?

Best Practice for Apache 2.0, Zope and SSL
by Rob Thorne 26 Sep '03

26 Sep '03

I've spent some time looking through Zope.org for some enlightenment concerning how best to use Zope with SSL, but there are many different tutorials, with different answers. What does the list currently recommend about the following options: * Is there a good patch for ZServer to support https directly, or should I run ZServer under Apache 2.0 with mod_ssl? * Do I need to use the Zope.cgi script, and if not, how do I get around it? * How is mod_proxy used with SSL, and how is this different from using mod_rewrite alone? * Is it better to use Virtual Host Monsters or the "Site Access" product to serve different sites from the same Zope instance. The various howtos and The Zope Book are all over the map on what to do in this case. I'm curious which solution performs best for multiple sites under one instance. Thanks, Rob

I am so lost.
by Bob Gailer 25 Sep '03

25 Sep '03

I was attracted to ZOPE by its power and integration with Python. Now I am experiencing extreme frustration, because I do not know how do to things that are essential, and don't know how to get the information I need. Reading the ZOPE Book, the Developer Guide, and the on-line help leave me stranded. What am I missing? Bob Gailer bgailer(a)alum.rpi.edu 303 442 2625 --- Outgoing mail is certified Virus Free.

Floundering Trying to Start Out
by Art Zemon 25 Sep '03

25 Sep '03

Help! I have some experience with other content management systems but I'm floundering with Zope & CMF. I have a site up and running (http://techcomm.us) but how do I do basic things like put a calendar on the left hand side of the page? I added a CMF Calendar Tool, and now portal_calendar shows up at the root of my CMF site... but now what? Any other pointers would be appreciated, too.
