DCOracle2 Beta 3
by Matthew T. Kromer 12 Jun '01

12 Jun '01

For all of you (or at least, BOTH of you<smirk>) Oracle users out there, I packed up DCOracle2 Beta 3 this morning, including Z Oracle Stored Procedures as part of ZOracleDA. It can be found in the usual place, http://www.zope.org/Members/matt/dco2 This isn't much different from Beta 2 except for some SP tweaks and the Z Oracle Stored Procedures, except that the NT builds are release versions with Oracle 8i (e.g. SP discovery code) features enabled -- when I built Beta 2 I goofed the build and packaged a debug release without the 8i specific features on. I'll confess that I'm not a heavy user of Stored Procedures, so your mileage may vary; particulary when using IN/OUT binds where type conversions need to take place from unweildy Oracle native types (like SQLT_NUM.) If you play with the stored procedure objects in Zope, it's probably worth pointing out that the default permissions won't include execute permission -- you have to specifically enable that for non-manager roles. On the far-out front, a few people have asked how you might do user-specific connections to the database (ie instead of pooling by a common connection, you individually authenticate to Oracle with your own password). Clearly, cloning the base Connection object would be fairly straighforward, but authenticating it to Oracle would not be, as the user password wouldn't be available. If anyone feels strongly about that (ie you have a notion on how you would make it work and/or you need it), feel free to write me. From a performance standpoint it would be terrible, but security auditors would love it.

Hi Casey, Did you get the code I sent you? I already have a solution from Gregor Heine similar to the one described below. It is in the "download" method in Document.py. It works too.

How to return downloadable content from Python Method
by Blandford, Simon [BSS Audio UK] 12 Jun '01

12 Jun '01

I am compressing files which need to be uncompressed inline before download. The DTML <href=...> calles a python method in the product which returns the uncompressed file data. Say this file is an MSWord document, how do I return this as a file to download? Presently, the browser just tries to display the binary file and makes a mess of it. Regards, Simon B.

Non-undoable storage
by Morten W. Petersen 12 Jun '01

12 Jun '01

Hia guys, during testing of a mail product I've discovered that the Data.fs file may bloat considerably after storing 50 messages. Packing the database will reduce the Data.fs file to 20 MB (from 40 MB). Another thing is that storing 50 messages takes a *long time* on a 600Mhz 256 MB RAM system. The thing that struck me was that transactions may cause a lot of overhead, both in database size and for execution speed, so, the thing I'm wondering about is if there exists a non-undoable storage, or something similar that doesn't support transactions.. Another thing I noticed BTW, is that retrieving 500 messages and packing the database on every 50th message (all messages retrieved during one request) would lead to off the charts memory usage, the process ended up using 700 MB of RAM (had to add swap files as the footprint grew!) Cheers, Morten

I've put together the design for an extended version of Structured Text which I'd like some feedback on before I go too much further. At this stage, the design is explained via a series of user-level How-To's, e.g. Writing Documents Using Structured Text Plus.

Re: [Zope-dev] multiple servers!

Stian, It's probably nicer to use the -P option for z2.py which allows you to specify a port offset for all ZServer services. ie. -P 8001 puts http on 8081 and ftp on 8022 or -P 8002 puts http on 8082 and ftp on 8023 --Tim _____________________________________________________ Tim McLaughlin Iteration Zero - www.iterationzero.com 703-481-2233 Message: 8 Date: Mon, 11 Jun 2001 12:04:31 +0200 (CEST) From: Erik Enge <erik(a)thingamy.net> To: Stian Jenssen <stian.jenssen(a)nrk.no> cc: "'zope-dev(a)zope.org'" <zope-dev(a)zope.org> Subject: Re: [Zope-dev] multiple servers!

Edit the z2.py file in your zope/ directory, look for HTTP_PORT and adjust that to your needs.

RE: [Zope-dev] request.set
by Adrian Hungate 11 Jun '01

11 Jun '01

What this does is set a key/value pair in the REQUEST variable (Which is a sort of python dictionary, just with extra smarts). DTML will not let you do <dtml-call "REQUEST['record_ids']=0"> for security reasons, so the REQUEST variable has the .set method which performs the same function. Hope this helps Adrian... -----Original Message----- From: Derek Quayle [mailto:derek.quayle@b-online.com.au] Sent: Monday, 11 June 2001 05:47 To: zope-dev(a)zope.org Subject: [Zope-dev] request.set I am fairly new to Zope and still coming to grips with it.

Advanced REQUEST inside Python Class Problem
by Stephan Richter 11 Jun '01

11 Jun '01

Hello everyone, I try to access the REQUEST variable in a Python class, but in certain cases this gives me a real headache. If I call my object with <dtml-var ObjectInstance>, then I can refer to the request variable in my Python code with self.REQUEST But, if I try: <dtml-var "ObjectInstance">, then I cannot use self.REQUEST, since the namespace is somehow not passed. BTW, the same seems to be true with properties inside a parent object. For some reason, if I call __getattr__, the entire "global namespace" (REQUEST and Aquisition) does not work correctly anymore. Has anyone a clue for me? Regards, Stephan -- Stephan Richter CBU - Physics and Chemistry Student Web2k - Web Design/Development & Technical Project Management
