Compiling on BSDI 3.0; using Zope on iServer.com
by Phillip J. Eby 02 Jun '99

02 Jun '99

FWIW, I successfully built Python 1.5.2 and Zope 1.10.2 (w/PCGI) on a BSDI 3 system yesterday. I had to change Python's config.h to remove the HAVE_DYLD and to undefine WITH_THREADS, change LDSHSARED to 'ld -r', and generally avoid using shared objects except for Zope's C modules. Once I had a python that passed "make test", Zope built "out of the box" with no changes. I only had to make a hardlink from the cgi-bin directory to the generated Zope.cgi, and it ran beautifully the first time. Also for what it's worth, the box I built it on was a Verio (iServer.com) Virtual Server B ($95/month), but a Virtual Server A ($55/month) would probably work as well, since it's the same platform AFAIK. Some of the iServer engineers are now checking out Python and Zope for possible addition to their menu of "unsupported" products that you can install on your account automatically. If this works out well, it should be easier to get Zope on track for becoming an offering on Verio's lower-end virtual hosting products, among other things.

Access denied when reading empty field in DB
by Miller, John M. 02 Jun '99

02 Jun '99

Hello, I have a Z SQL method (querying through a Z ODBC connection to an Access database) that retrieves all the entries in a particular row in a table in my DB, as so: select * from [Verbal Requests] where [Case#] =  Most of the time this works jolly well (I'm still getting over how easy this was to set up in Zope after trying to use various wizards in Access, *shudder* FrontPage, and *double shudder* Interdev) except when it encounter a field with an empty value. The field it chokes on contains values of type Double. I have specified no default value in the database setup. The field is named 'Man Hours' (so that you can recognize it in the traceback). When a blank value is encountered the browser politely tells me "You are not authorized to access this resource" and gives me the following traceback: Traceback (innermost last): File C:\Program Files\ZopeEdge\lib\python\ZPublisher\Publish.py, line 255, in publish_module File C:\Program Files\ZopeEdge\lib\python\ZPublisher\Publish.py, line 157, in publish File C:\Program Files\ZopeEdge\lib\python\ZPublisher\mapply.py, line 154, in mapply (Object: index_html) File C:\Program Files\ZopeEdge\lib\python\ZPublisher\Publish.py, line 98, in call_object (Object: index_html) File C:\Program Files\ZopeEdge\lib\python\OFS\DTMLDocument.py, line 181, in __call__ (Object: index_html) File C:\Program Files\ZopeEdge\lib\python\OFS\DTMLDocument.py, line 177, in __call__ (Object: index_html) File C:\Program Files\ZopeEdge\lib\python\DocumentTemplate\DT_String.py, line 514, in __call__ (Object: index_html) File /Program Files/ZopeEdge\lib\python\DocumentTemplate\DT_In.py, line 675, in renderwob (Object: get-vr-details) File C:\Program Files\ZopeEdge\lib\python\DocumentTemplate\DT_Util.py, line 315, in eval (Object: _vars['Man Hours']) File <string>, line 0, in ? File C:\Program Files\ZopeEdge\lib\python\DocumentTemplate\DT_Util.py, line 150, in careful_getitem Unauthorized: (see above) I am thinking this problem stems from having an empty (null?) value in this field when it is expecting a floating-point value. I imagine configuring the Access database to provide a default value for this field will make this go away. Does anyone else have a better idea? I did some thinking along the lines of capturing this situation and providing a slightly more elegant response, i.e. displaying all the fields expect the empty one, but my Zope lore is woefully insufficient. I am happy to provide any additional details that you so require, Much thanks, John Miller

You can write an external method that uses the Python hasattr() function to check for the attribute; strangely the _ namespace has a "getattr" function, but none for checking the existence of an attribute. My own implementation looks like this: def HasAttr(Obj, Attr): return hasattr(Obj, Attr) This works with Acquisition. -- Alexander Staubo http://www.mop.no/~alex/ "It has taken the planet Earth 4.5 billion years to discover it is 4.5 billion years old." --George Wald

I've never tried BSDI 4, but here are some things I remember doing once to get it compiled on BSDI 3.x box: o add -rdynamic to LDSHARED in all of the Makefiles o run make -k and ignore any error messages o I also seem to remember that this produced extensions as .o files, which I then had to rename to .so...

Martijn, Remember that DTML Documents behave a little differently than DTML Methods, External Methods and other "method"-like objects. The "self" in your "getPropertyIds" external method is going to be the _folder_, not the DTML Document. In a DTML Document, the implicit "self" namespace is the DTMLDocument itself, but this does extend to any method-like objects called from the DTML Document - they will continue to act as methods of their containers (and _not_ like methods of the DTML Document). One thing you could do to accomplish what you are trying to do is to extend your getPropertyIds() method to accept an argument: def getPropertyIds(self, obj): return obj.propertyIds()  Hope this helps!

I had to copy the /content-directory of the python, which came with Zope in the python directory of my debian-linux installation. (Python 1.5.1) Then the compilation worked.(make -f Makefile.pre.in boot ) But now I have a problem with the make command: gcc -fpic -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5 -DHAVE_CONFIG_H -DADABASSQLAPI -I/usr/local/stow/adabas/incl -c ./sql.c ./sql.c:44: Python.h: Datei oder Verzeichnis nicht gefunden make: *** [sql.o] Error 1 Sorry it is my first step with python ...

Re: Is pcgi usable without Zope?

Or is there a way to run pcgi without > Zope? Lloyd, PCGI is a tiny, yet integral part of Zope for some set of Zope applications, esp. where a web server front-end (e.g. Apache) is desired. It is possible to run Zope without PCGI (e.g. internal network, a.k.a. buzzword: 'intranet'). It is also possible to use PCGI without Zope. The pcgitest example is provided to test and demonstrate a free-standing PCGI application. And yet another alternative is to use PCGI with Zope components (ZPublisher, DocumentTemplate, BoboPOS) to build custom solutions. the-tyranny-of-choice-prevails-ly yr's Jeff Bauer Rubicon, Inc. P.S. A couple weeks ago I posted a message describing a new version of pcgi_publisher that would include an inactivity timer, i.e. would shutdown the LRP automatically after a specified period of inactivity. I think some people may find such a feature useful for custom PCGI apps. -JB

web store
by Graham Chiu 02 Jun '99

02 Jun '99

I'm looking to convert my perl based web store ( which uses flat ascii files ) to Zope, and am looking for pointers on how to do this. The perl application uses dynamically generated HTML, and a sessionid variable which identifies the customer, and this is passed from page to page. The shopping basket is saved with the sessionid as a text file between pages. I've got to the point on how to access sql tables using Zope, but am wondering how to do the sessionid bit. I don't think I need to do authentication at this stage. Is there a working webstore type product around? ( I did download the emarket product, but when I tried to add an item to the basket, it then displayed the dtml to my browser! Furthermore I wish to grab the item from a sql table which emarket does not do. ) ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz
