ZPublisher or Bobo and stdout
by Dr. Armin Tschammer 02 Mar '99

Hi, The followowing problem seems very fundamental to me. I already did a post to this group to this topic and I got the following answer: On Wed, 13 Jan 1999, Dr. Armin Tschammer wrote: > I publish the following Modul with Bobo: > Very simple: > > hello.py: > > import sys, os, time > import DocumentTemplate > > lib=sys.path[0] > sys.path.append(os.path.join(lib,'DT')) > > def hello(): > "Display a greeting" > # print "rrr" > X3 = DocumentTemplate.HTMLFile(lib+'/hello.dtml') > return X3() > Now, when I make the commentated line print "rrr" active, I get > Internal Server Error The "print" goes directly to the webserver, which confused it: it expects HTTP headers like "HTTP/1.0 200 Okay". The "return" sends your data to *Zope*, which then does the header stuff for you. Same with cookies, content-type, etc. Summary: dont use 'print', or redirect stdout to a log file. Now the problem is deeper, what shall I do when I am import C++ Modules in Python ( extending Python), and that modules are writing to the stdout via "cout" or "printf", I have no influence to that. If I change the stdout via "freopen( "file, "wr", stdout )" or stuff like that, I have no chance to switch back to the *real* stdout ( look at the c-faq of comp.lang.c ), and I *have to* switch back because of the cgi-mechnism, which uses ZPublisher. The only the chance to handle stuff like that is to work with two processes in the Zopemechanism. A Zopeserver which tells the Zope Client to start a pythonfunction. Now all stdout happens on the client and the server listen for a string on a socket ( or something similar ). Now when the server gets the string it does all necessary wrapping ( content-type and so on ), and send it to the Xserver via its stdout. Or is there a less complicate solution ? Thanks in advance Armin

RFQ: Upgd Netscape 2.x auth patch to Netscape 3.5.x
by Rob Page 02 Mar '99

02 Mar '99

Hello everyone: Some of you may know that many moons ago we (Brian) developed a plug-in for Netscape Enterprise Server (ES) 2.x (and FastTrack -- based on the same libraries) that addressed Netscape's nasty habit of removing authenticated_user information from the environment before calling CGI apps. Obviously, this has a deleterious effect on interesting zope applications. Fortunately (?), we are up to our armpits in projects and initiatives. As a result, we need someone to do a bit of work to upgrade the plug-in from ES 2.x to ES 3.5.x. I can provide the following files from our 2.x incarnation: o plug-in source code o obj.conf o magnus.conf The source code is only 153 lines of generously formatted C (w/lots of defs) so I'm hopeful that this isn't a HUGE task. I'm interested in hearing quotes from people in the community that have experience with the NSAPI and would, for a reasonable fee, develop, compile (Solaris 2.6 and NT4) and test an upgraded plug-in. The work would be contributed back under the ZPL. Naturally, I'd also entertain offers from people to do this for free! :^) --Rob P.S. - I KNOW there are some NSAPI wizards out there so don't be shy! -- Rob Page V: 540 371 6909 Digital Creations http://www.digicool.com

trouble running zope-1.10.2 (freebsd, python 1.5.1)
by Oyvind Moll 02 Mar '99

02 Mar '99

Trying to get started with Zope on a FreeBSD machine. I did the following: * Downloaded source distribution of Zope-1.10.2 * Extracted it * cd into directory and ran 'python wo_pcgi.py' (no error messages) * ./start I then get the following in var/serve.log (slightly edited for slightly more readability): Traceback (innermost last): File "serve.py", line 90, in ? ZopeHTTPServer.main(sys.argv[1:]+[os.path.join(os.getcwd(),'lib','python','Main.py')]) File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/ZopeHTTPServer/ZopeHTTPServer.py", line 498, in main start(module_file,host,port,threading,env) File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/ZopeHTTPServer/ZopeHTTPServer.py", line 436, in start set_published_module(module_file,BoboRequestHandler,env) File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/ZopeHTTPServer/ZopeHTTPServer.py", line 432, in set_published_module __import__(name) # to catch problem modules right away File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/lib/python/Main.py", line 90, in ? from BoboPOS import SimpleDB, TJar, SingleThreadedTransaction File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/lib/python/BoboPOS/__init__.py", line 99, in ? import SingleThreadedTransaction, Persistence, PickleDictionary File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/lib/python/BoboPOS/SingleThreadedTransaction.py", line 110, in ? from PickleDictionary import PickleDictionary File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/lib/python/BoboPOS/PickleDictionary.py", line 91, in ? import marshal,time,Persistence,SimpleDB, PickleJar File "/usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/lib/python/BoboPOS/SimpleDB.py", line 104, in ? from cPickle import Pickler, Unpickler ImportError: /usr/home/taiga/oyvindmo/work/Zope-1.10.2-src/lib/python/cPickle.so: Undefined symbol "PyExc_IOError" I don't have any experience with Zope or even Python, but am I right in guessing that this looks like a problem with the python binary and not with Zope? Any ideas to precisely what the problem might be? python is v1.5.1. C compiler used is gcc 2.7.2.x. -- Øyvind Møll oyvindmo(a)pvv.ntnu.no

It doesn't help that distributions like RedHat 5.2 ship it in a broken way, then people blame us for it, then we track down a problem that is completely outside Zope. Did you follow the recommendations to start with the built-in webserver before trying integrate with Apache? If so, did that work? --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

I have 1.5.1 and it failed for me. Is the zlib.pyd in 1.5.2 based on a newer version of the zlib library that may not be forward compatible? -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out!

Request.py and duplicate column names
by TFE MMS JARVIS JOHN 02 Mar '99

02 Mar '99

Hi All! First off, I'd like to thank Digital Creations for an excellent (and really fun) product. I'm building a prototype web site interface for a database where I work using Zope 1.10.2 and the ZOracleDA product and have a some questions. 1. When trying to do a join (a lazy query, I know) like: select a.*, b.* from tablea a, tableb b where a.b_id=a.id Both tables have an ID column so Zope raises a 'ValueError' exception with the message 'Duplicate column name, ID'. I wonder if instead of raising an exception something like the following could be done? A diff of Shared/DC/ZRDB/Results.py: 120,131c120 < #raise ValueError, 'Duplicate column name, %s' % name < < #instead of error, append an extension to < #create a unique name < tempname=name < nameext=1 < while schema.has_key(name): < name=tempname+'_'+str(nameext) < nameext=nameext+1 < < #update with newly created name < item['name']=name --- > raise ValueError, 'Duplicate column name, %s' % name I tested this some and it seems to work. Are there any problems that could be caused by doing this? 2. I'll post the other questions separately because they are unrelated. TIA!, John Jarvis Tokyo Electron, FE Ltd.

Not really -- you can't access _getPassword() from DTML. You would have to write an external method to do that (which implies that you have access to the filesystem, and could get the passwords anyway if you wanted them that bad...)

Zope needs a FAQ.

Zopistas Seems that the activity on the Zope list has exploded. A lot of the questions I read in the posts have been raised many times in the past. I believe a FAQ on the Zope site is neccessary. Do the folks at digital creations have time to set it up? Pavlos
