set accessrule

Hello, I have difficulties with accessrule. I am using zope 2.5.0 I have a folder named testfolder. For this folder I have set accessrule to the python script accessruleHB, which is in folder testfolder. ----------------------------------------- ## Script (Python) "accessruleHB" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=REQUEST=None ##title= ## # Import a standard function, and get the HTML request and response objects. # from Products.PythonScripts.standard import html_quote session = context.REQUEST.SESSION sessionId=session.get('MySessionId') if sessionId == None: REQUEST.RESPONSE.redirect('/rootfolder') ----------------------------------------- But it seems that this script is not called automatically by set accessrules, because nothing happens. What I want is: If sombody is accessing folder testfolder, accessrule for this folder should call accessruleHB to redirect people (and thus to deny access) if they are not authorized. If I run the script standalone ( by calling it) it redirects to rootfolder. What have I done wrong with setaccessrule ? With kind regards, Juergen Berger

Help! Lost Management interface!
by Kevin Carlson 21 Mar '02

21 Mar '02

Hi, I seem to have lost the ability to get the management interface of Zope to respond (or do anything). The Zope site itself still responds but when I add "/manage" to the base URL and enter a username and password (correctly) the site hangs. Occasionally I get the manage_top_frame to display, but the other two frames don't display at all. I can enter a subarea of the site (e.g. http://localhost/test/manage) and that works fine, but the Root Folders management interface is non responsive. Any ideas? Thanks, Kevin

How to use double quotes (") in a string in a python expression in dtml
by Igor Leturia 21 Mar '02

21 Mar '02

Hi all! I want to check in dtml if a string variable contains double quotes ("), so I include a python expression in a dtml-if, something like this: <dtml-if "_.string.find(s,'"')<>-1"> Of course, this doesn't work as the dtml interpreter thinks the " is the end of the python expression. But I tried it with \" also, and it doesn't work. Any ideas? Igor Leturia

ZCatalog Update hangs Zope
by oliver.erlewein＠sqs.de 21 Mar '02

21 Mar '02

Hi all When Updating the ZCatalog manually from the management interface Zope hangs itself up. Apache reaches the timeout and returns an error after 5 Minutes. Zope never comes back. After a restart all's fine again. I don't know whether ZCatalog did an update. Same thing happens when Cataloging the whole Site. (Zope 2.4.0 (Solaris)) I have manny "unable to uncatalogObject" errors in my Stupid.log. Regards Oliver Erlewein

testing for folders
by Tom Cameron 21 Mar '02

21 Mar '02

I am trying to traverse all children of a folder and find all users in all userfolders. I have discovered the following attributes: isAUserFolder isAnObjectManager isPrincipiaFolderish Which I guess were created for this type of task. But I am not sure what the difference is between 'isAnObjectManager' and 'isPrincipiaFolderish'. Could someone explain when I should use each of them. Thanks Tom

How to start zope in more than one group
by Fischer Ulrich 21 Mar '02

21 Mar '02

Hi normaly, zope is started as root and runs as user 'nobody' or a predefined user 'zuser'. I use zope (Zope 2.3.3) in the second way on SUSE Linux7.2. Zope is connected to Apache. The 'zuser' is in the user groups A, B, C, ... The membership in group 'A' is defined in the passwd file ('user's primary group'), the other memberships are defined in the group file. My problem is, that z2.py reads only the 'user's primary group' in the passwd file. But I need for full functionality all the grouprights of the user 'zuser'. Is there a possibilty to fix this? Do I have to change z2.py, when, how (I only know how to write 'python') z2.py (the part where the gid is set) : : # Try to set uid to "-u" -provided uid. # Try to set gid to "-u" user's primary group. # This will only work if this script is run by root. try: import pwd try: try: UID = string.atoi(UID) except: pass gid = None if type(UID) == type(""): uid = pwd.getpwnam(UID)[2] gid = pwd.getpwnam(UID)[3] elif type(UID) == type(1): uid = pwd.getpwuid(UID)[2] gid = pwd.getpwuid(UID)[3] else: raise KeyError try: if gid is not None: try: os.setgid(gid) except OSError: pass os.setuid(uid) except OSError: pass except KeyError: zLOG.LOG("z2", zLOG.ERROR, ("can't find UID %s" % UID)) except: pass : : Thanks Best regards Ulrich _______________________________________________________________ Ulrich G.

System performance threads/proccesses & random crashes (SIGPIPE)
by Doyon, Jean-Francois 21 Mar '02

21 Mar '02

Hello, I'm running into random crashes of my zope processes, but I'm not finding any reference anywhere in the mailing list archives or on the site about this specific one: I'm getting: 2002-03-21T14:48:52 ERROR(200) zdaemon zdaemon: Thu Mar 21 09:48:52 2002: Aiieee! 20070 exited with error code: 13 Every now and then, for now apparent reason. signal 13 is a SIGPIPE ... This is Zope 2.5.0 with CMF 1.2 on a severly upgraded/updated/patched RH6.2 ... with a Python 2.1.2 built with defaults. It runs with FastCGI to Apache 1.3.2x ... Usually I just wait a couple of seconds, hit referesh in my browser and things come back to normal, but it's still annoying, and doesn't look good to the public. Note that when this happens, it ususally seems to happen to ALL processes. It looks to me like the PIPE's between the master zope process and it's children dies, and they all have to restart for some reason. Could this be ? and if so , why ? Note that I started noticing this when I for the first time started using Psycopg to create RDBMS connections to my PostgreSQL ... Could there be a relation somehow? On a slightly similar topic, How to I manage performance? I plan on using Zope for a fairly high demand web site .. I noticed I can control how many processes/threads start, but then I also read somethign about the ZODB pool_size ... What is the relation between the two exactly ?

(Sorry forgot the Subject - therefore repost) Hi Paul I tried to find out more on my systems but all I have are the values below. I rechecked all of them. 1) SUN 420R, 4x450Mhz UltraSparc II, 4GB RAM, Sol. 8 2) DELL 19" rack, 1xPIII 1Ghz, 512Mb RAM, Sol. 7 Both have the same problem with threading. The computers were set up by two different ISP's. So the problem probably won't be a specific config thing!?? Oliver Erlewein
