Problem with Zope 2.0.0b1 and Apache
by JOHN COOK 01 Aug '99

01 Aug '99

Hi, I have been able to get Zope running with ZServer fine, but I would prefer to run it using Apache, as I am already hosting other sites with Apache on the same box. I get an "Internal Server Error" and when I look in the pcgi.log file, I get the following statement: Sun Aug 1 06:56:28 1999 unable to publish module Traceback (innermost last): File "/usr/local/zope/pcgi/pcgi_publisher.py", line 303, in handler self.publish_module(self.moduleName,stdin=stdin,stdout=stdout,stderr=stderr,environ=env) File "/usr/local/zope/lib/python/ZPublisher/Publish.py", line 265, in publish_module response.exception(1, v) File "/usr/local/zope/lib/python/ZPublisher/HTTPResponse.py", line 600, in exception if isinstance(b,Exception): b=str(b) TypeError: second argument must be a class Any help would be greatly appreciated.

bug: manage screen renders index_html?!
by Alex Rice 01 Aug '99

01 Aug '99

If I remember correctly, seems to be a new bug in 2.0 beta1. Sometimes the manage screen renders index_html in the right-hand frame, instead of manage_main! This is definitely the wrong behavior. Usually it can be worked around by just clicking on the desired folder in the left hand frame. I see this occasionally on Netscape 4.61/Linux, but I was just speaking with someone who was using Netscape 4 on WinNT4 and they were seeing the index_html even no matter what subfolder they clicked on in the left hand frame. In other words, the management interface was almost totally inaccessable to them. I would post this to the collector, but the zope site is just crawling right now. I'm seeing severe packet loss around exodus.net your upstream provider. Zope 2.0 beta 1, Linux, ZServer, Py 1.5.2 -- Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice Current Location: N.

Depends what the meaning of the words "in Python" is... :^) You could write an External Method in Python: import os some_script_output = os.popen("some_script.pl",'r').readlines() some_script_output is then a list of lines of output. In this example some_script.pl is in perl. If you weren't interested in the output (i.e., you just wanted to run something), you could (I think) use: import os os.system("some_script.pl") --Rob

Q. on Persistence.Persistent
by Alex Rice 01 Aug '99

01 Aug '99

Suppose I have a zclass which inherits like this my_ZClass( my_python_class( Persistence.Persistent,Acquisition.Implicit)) In my_python_class, I have something like the following segment: def doStuffToCount(self, newcount): _count=self._count # get persistent count _count=_count+newcount # increase count ... # maybe do other stuff self._count=_count # save persistent count again return _count My reading of Michel P. and Jim F.'s posts in recent threads about Persistence and ZODB3, is that this this method above is basically an atomic opertation as far as ODB3 is concerned, and I do not have to worry that another thread is going to touch self._count in between _count=self._count and self._count=_count. Is this correct? If I am misunderstanding, is there the equivalent to java's synchronized keyword that one would use in this scenario?

Installation question
by Francisco Sam Castillo 01 Aug '99

01 Aug '99

Hello, I am new to Zope and I just subscribe to the list, I hope this is the right place for this, I have succesfuly installed Zope 2.0.0b1 on Linux RH 6.0 Distribution on my local station, but when I tried to do this on my ISP server which uses the slackware distribution the installation just goes on and finishes, modules get compiled but when I execute the start script, it sends many error regarding importing modules and the server just will not start, has any one expirienced this ? (I guess it has something to do with the slackware distribution because I try it at 3 servers all with it and had the same results and on RH it works). I had so much hopes for this to work on my site but had no luck, I do have installed the Python 1.5.2 as required. Hope some one has the time to help me out, and I thank you in advanced fro any help or advice you can give me to solve this. BTW Zope is a great tool I want to congratulate the development team, all people involved, who have made it possible it's just the best integrated system for development I have ever seen. Sam

Couple of 2.0b1 observations on win98
by zzzz tttt 01 Aug '99

01 Aug '99

I am trying zope 2.0b on the win98 desktop (eventually will move to redhat when I understand it <g> ); Extremely impressed with the system. A couple of points: (i) Keep getting an error when I try to create a date property (string is ok) following the lead from the manual (for 1.x) (ii) Got an error when tried to upload an image (file is ok) from the server itself (browser on server); uploading from elsewhere is ok. I assume there is no earthly way to get zope to run external cgi-scripts or executables (with Zserver that is; for the moment I am using zserver) unless the script is in python.

Gadfly Problem with 2.0b?
by Jesse D. Sightler 31 Jul '99

31 Jul '99

I was testing out Gadfly 2.0b on my 486 server here <g>, and it seems that I can't get Gadfly to read an existing database. All that I did was copy the files for the database over from /usr/www/users/jsight/biddin/pyPit/programsdatabase to /home/jsight/Zope/var/gadfly/programsdatabase. I did a cd to the database's directory under Zope and opened up the Python interepreter and opened the database with "connection=gadfly.gadfly('.','pyProgramsDatabase')". This worked, so I got a cursor and did a "cursor.execute ('select * from pyLibraries')" and printed the results. All was fine up until this point. Then I used my browser to open the management screens for Zope, added a connection to "programsdatabase" and added a new SQL method with no arguments which consisted of "select * from pyLibraries". However, from here when I click add and test it tells me that there exists no relation pyLibraries! Could someone please explain to me why this might happen? Perhaps there is something that I am missing in regards to how to actually setup the database connectin? All of the status screens say that the connection is open, though. Here is the full output from the test: Z SQL Method at /pyPit / all_entries Error, exceptions.NameError: 'PYLIBRARIES' no such relation in DB SQL used: select * from pyLibraries Traceback (innermost last): File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/ZPublisher/Publish.py, line 256, in publish_module File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/ZPublisher/Publish.py, line 161, in publish File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/ZPublisher/mapply.py, line 154, in mapply (Object: manage_test) File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/ZPublisher/Publish.py, line 98, in call_object (Object: manage_test) File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/Shared/DC/ZRDB/DA.py, line 310, in manage_test (Object: all_entries) File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/Shared/DC/ZRDB/DA.py, line 291, in manage_test (Object: all_entries) File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/Shared/DC/ZRDB/DA.py, line 395, in __call__ (Object: all_entries) File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/Products/ZGadflyDA/db.py, line 175, in query File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/Products/ZGadflyDA/gadfly/gadfly.py, line 339, in execute File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/Products/ZGadflyDA/gadfly/sqlsem.py, line 2604, in relbind File /home/jsight/Zope-2.0.0b1-linux2-x86/lib/python/Products/ZGadflyDA/gadfly/gfdb0.py, line 305, in bindings NameError: (see above) -- --------------- Jesse D.

Question about users...
by djb＠redhat.com 31 Jul '99

31 Jul '99

Okay, I'm a Zope newbie. I installed it on my laptop to muck with it, and so far I'm impressed. But I'm having some trouble...I tried to create a new user and add that user to the "Manager" role. I then changed the permissions in the Security tab to let Manager have some privs to do things. The only problem is, no matter what I try, I can't log in as that user. I would have thought I could just pull up a browser on another machine somewhere, point it at my laptop, and log in. I can do this as the superuser, but not as the new user I created. Not at all. I don't see much in the docs about logging in as another user, either. Nor do I even see how to log *out* once you log in as the superuser (help?). All this is using the 1.10 RPMs linked from zope.org, as well as the zserver instead of running with apache. Help? --Donnie
