zope access to external files
by Ricardo Anguiano 05 Mar '03

05 Mar '03

Greetings All, Some stats on my (stale, and soon to be updated) setup: Zope Version (Zope 2.4.1 (binary release, python 2.1, linux2-x86), python 2.1.0, linux2) Python Version 2.1 (#2, Jun 22 2001, 10:20:42) [GCC 2.7.2.3] System Platform linux2 I have a couple of objectives: 1. I want to restrict file access by user. 2. I want to serve objects from zope to accomplish objective #1 above, but I want the objects to be in the filesystem. I want to be able to say, "The contents of directory X are available only to user Y." I looked through the list of products in the "External Access" category and there were a couple of good candidates. The localfs listing was hard to find but it did turn up in a faq somewhere. http://www.zope.org/Members/arielpartners/ExternalFile http://www.zope.org/Members/MacGregor/ExtFile http://sourceforge.net/projects/localfs Questions: Can anyone recommend one of these products over the other? Will they let me do what I describe? Are there products which are a better fit? Is there an easier/better way? My apologies if this has been answered in the mailing list recently. An archives search did not turn up anything. Thanks in advance, -- Ricardo Anguiano http://www.codesourcery.com

>It doesn't need to be named. Call your python script via the dtml-in, return >foo, and all will be well. I do it all the time. But what I want to do is the opposite: to call the dtml-method from the python script with the list as an argument.

That's terribly unlikely to be blocked. I'm assuming you can see that the Python processes are running: if so, perhaps you can try the scripting-Zope-by-ZEO method to see if anything actually is happening. And do you get anything by way of log activity or console output ? (assuming this Windows Server thingy has a console...) --jcc

I'm locked, I can't change anything I modified in a "experimental" version and of course I was not very cautious in my experimentations.. Traceback (innermost last): Module ZPublisher.Publish, line 102, in publish Module Zope.App.startup, line 200, in commit Module ZODB.Transaction, line 235, in commit Module ZODB.Transaction, line 349, in _commit_objects Module ZODB.Connection, line 391, in commit - __traceback_info__: (('OFS.Folder', 'Folder'), '\x00\x00\x00\x00\x00\x00\x11\x87', '') Module ZODB.FileStorage, line 726, in store VersionLockError: ("'\\x00\\x00\\x00\\x00\\x00\\x00\\x11\\x87'", '/danielle/philosophie_africaine/version_exp') with the help of google, I could find a recipe May be you could open the database and try this:> > >>> db = ZODB.DB(fs)> >>> db.abortVersion('content_cntrl')> >>> get_transaction().commit()> >>> db.close()but it's a little bit indigestible for a newbie.. what will happen if change my full.py to take the newest from the cvs? is it safe? thanks

Has anybody tried Zope on Windows Server 2003. >From what I can tell it installs ok -- and appears to be running but attempts to access it via webbrowser ( locally ) fail. Is there something obvious I might be missing?

Hi, Finally got it to work, well almost... I had to use python 2.1 to compile PIL, also, Zphotoslides, the zope product that started it all, requires PIL 1.1.3. Now the product appears, I created a zphoto slide folder. After I had put some pictures in it, if I make changes to a photo, these will appear in preview, but when clicking on modify, get message: Nothing has to be done. But that is another story... PIL is working. It's a long an winding road, all this to have some pictures of my new dog on the net :-) Thanks all, Francois > -----Original Message----- > From: Dennis Allison [mailto:allison@sumeru.stanford.EDU] > Sent: March 4, 2003 6:42 PM > To: Meehan, Francois > Cc: 'Dieter Maurer'; 'zope(a)zope.org' > Subject: RE: [Zope] RE: Installing PIL on binary dist. of > Zope 2.6.1 on > Li nux... > > > > On Tue, 4 Mar 2003, Meehan, Francois wrote: > > > > Since I have python 2.2 on my system, and did compiled PIL > with that, > > copying PIL in Zope/lib, the mix of python version might > create the problem. > >B > > How can I compile PIL with the python version that comes with Zope? > > > > Follow the same procedure you used to install PIL under > python2.2.

Indeed, By running /home/zope/bin/python, import _imaging gives: ImportError: /home/zope/lib/python2.1/_imaging.so: undefined symbol: PyType_IsSubtype Since I have python 2.2 on my system, and did compiled PIL with that, copying PIL in Zope/lib, the mix of python version might create the problem. How can I compile PIL with the python version that comes with Zope?

python variables rendered by dtml
by jwsacksteder＠ramprecision.com 04 Mar '03

04 Mar '03

This is going to sound convoluted, but trust me, it's this way on purpose. I have a python script that gets a result back from an unparameterized zsql query like this- foo = container.get_stuff_sql() I then make some alterations to 'foo' in my script which I will leave out for clarity. I then want to render 'foo' from a dtml method with a dtml-in clause. What is to best way to pass 'foo' into the dtml method? (I'm having internet problems and I can't get to Zope labs right now, or I'd look it up myself.)

RE: [Zope] persistent object with non-persistent attributes
by sean.upton＠uniontrib.com 04 Mar '03

Thinking aloud: ...so myNonZopeClass instances need to be a singleton-like thing, with some sort of mutex-ish of lock to prevent other instances from being constructed? I wonder if there is a way to throw an exception on construction of a myNonZopeClass instance if another Zope thread has an instance. Perhaps you could keep an external boolean lock variable in a module-level global accessible to all threads, but it might just be easier to follow Toby's suggestion and just see if you can keep your myNonZopeClass instance object in a module-level global, and just keep a reference to it in a _v_ attribute? I've never tried anything like this, might something like this possibly work?

This is perfect ! But now how can I be use that no other thread access the hardware at the same time ? (if possible a single device open at Zope start or on-demand would be fine) I actually use a CGI script for this, but I wondered if using Zope instead wouldn't make it more "reactive".

Thanks all. Unfortunately I specifically need credit card transaction handlers, since that is the nature of our customer base. I will report my experiences regarding the vendor I choose to the list in the hopes that it might be useful to someone. AM Marc Burgauer wrote: >If you want to go down the easy route, use PayPal.
