Hi all, I tried to install Zope 2.7.0(tar ball) on RedHat 9.0 w/ Python 2.3.3 installed. When I run /path/to/runzope I got the following error message 2004-05-06T08:27:59 PANIC(300) Zope A user was not specified to setuid to; fix this to start as root (change the effective-user directive in zope.conf) Traceback (most recent call last): File "/opt/Zope-2.7/lib/python/Zope/Startup/run.py", line 49, in ? run() File "/opt/Zope-2.7/lib/python/Zope/Startup/run.py", line 19, in run start_zope(opts.configroot) File "/opt/Zope-2.7/lib/python/Zope/Startup/__init__.py", line 48, in start_zope starter.dropPrivileges() File "/opt/Zope-2.7/lib/python/Zope/Startup/__init__.py", line 203, in dropPrivileges return dropPrivileges(self.cfg) File "/opt/Zope-2.7/lib/python/Zope/Startup/__init__.py", line 319, in dropPrivileges raise ZConfig.ConfigurationError(msg) ZConfig.ConfigurationError: A user was not specified to setuid to; fix this to start as root (change the effective-user directive in zope.conf) I modified the effective-user parameter to root won't work either. I had search on google and read the readme but can't find any hint don't know if this had ever happen to others. Any help? Thanks for your time JH

cookie help
by schandra＠csee.wvu.edu 06 May '04

06 May '04

Hi, I am having some problems with the authentication logic.My application uses three roles--Student,Faculty and staff.I use my login page(cookie authentication) to collect the username and password and I use the LDAP directory to authenticate.The authentication works fine but when I log out and hit the back button in the browser,I am still going to the secure page and not redirected to the login page.I check for roles in all pages.I think my way of expiring the cookie is not correct. For logout, I use the following statements for cookie expiration bu tit deosnt work. Can you see whats wrong? <dtml-call expr="RESPONSE.expireCookie('__ac',path='/')"> <dtml-call expr="SESSION.invalidate()"> Thanks in advance, Srini

put_factory
by Arenz, Ralph 06 May '04

06 May '04

Hi all, i've developed and registed a own python-class as ZClass and ZBaseClass in Zope. Now i want to create a new (pure) ZClass with the ZBaseClass as subclass and force ftp/webdav to use this ZClass for uploading. If i write the put_factory for the python-class it works well, if i try to use the put_factory for the pure ZClass i run in trouble. Is it possible to use put_factory in the context of pure ZClass anyway, and how do i have to call the ZClass constructor? ralph

ID update fails to change ID in ZMI
by pieter claassen 06 May '04

06 May '04

I have the following code and when I update the edit through the editform interface, then the id in the ZMI does not change. When I try to rename the item, it works as long as the internal and ZMI values are the same, otherwise I get weird errors: 1. If they are different and I rename the id through the ZMI to something new, it stack traces. 2. If they are different and I rename the id through the ZMI to the internal representation, then no error but also no change to the value in the ZMI. Any comments? Thanks, Pieter 46 _editForm=DTMLFile('dtml/edit',globals()) 47 48 security.declareProtected('View management screens','editForm') 49 50 def editForm(self,REQUEST,manage_tabs_message=None): 51 "returns the edit form" 52 return self._editForm(REQUEST,globals()) 53 54 security.declareProtected('Change shopping item','editItem') 55 56 def editItem(self,id,REQUEST=None,RESPONSE=None): 57 "Edit a shopping item" 58 self.id = id 59 if REQUEST is not None: 60 message="Item_updated" 61 return self._editForm(REQUEST,manage_tabs_message=message)

Re: Zope-2.7 both http and https in parallel?

It adds a <https-server> stanza > identical to <http-server> but adding the HTTPS ON header > automatically. Hi Stefan, thanks for the reply, this looks very helpfull. For those who don't want to patch the sources, I've found another solution, that seems to work quite well: add an access rule like this: request = container.REQUEST if request.SERVER_URL[-4:] == ':443': request.setServerURL(protocol='https') #request.setServerURL(protocol='http', port='80') The second commented line seems to be an interesing option if you don't want every URL to be "https". I tried this with a pound proxy in front, but this should work without as well.

In earlier ZODB versions (that distributed with Zope 2.6.x), "clear" caused a SIGSEGV. Then, I used "minimize" instead of "clear". The current ZODB version (that distributed with Zope 2.7) does not have problems with "cache.clear()". We use it without problems. -- Dieter

Great. That did it. Thanks for the prompt response.

Calling with the parenthesis gets you an object which you can then call strftime on. The syntax may not be exactly right, but you get the idea.
