using exceptions in python scripts
by roy＠anoobe.com 31 Jan '02

31 Jan '02

Dear Zope Users, Fairly new to Zope, but I am writing a Python Script. I would like to use exceptions in my processing flow, but the security restrictions won't allow it. What is the recommended approach here? For example, what I would like to do, but am not allowed to, is: # sample_py ---------------------------------------- request = container.REQUEST RESPONSE = request.RESPONSE try: username = request.get("username", None) if len(username)==0: raise "ZeroLengthUserName", None except: import sys # SECURITY won't allow print sys.exc_type; return printed # process username here... # return another dtml document/method return context.registered_ok_dtml(context,context.REQUEST) # end sample_py ---------------------------------------- Thanks, Roy Mathew. ps: please respond directly to me as well, if you could.

RE: [Zope] Zope Logout
by entheos＠entheossoft.com 31 Jan '02

Looking at the source for manage_zmi_logout might help you. This is extracted from Zope/lib/python/App/Management.py: def manage_zmi_logout(self, REQUEST, RESPONSE): """Logout current user""" p = getattr(REQUEST, '_logout_path', None) if p is not None: return apply(self.restrictedTraverse(p)) realm=RESPONSE.realm RESPONSE.setStatus(401) RESPONSE.setHeader('WWW-Authenticate', 'basic realm="%s"' % realm, 1) RESPONSE.setBody("""<html> <head><title>Logout</title></head> <body> <p> You have been logged out. </p> </body> </html>""") return Basically, it sets the header requiring authorization and does nothing with it. This way, the browser (hopefully) decides it doesn't need to store anymore authentication information. It generally, doesn't work that way though. Troy > Todd, thank you for your reply.

You ran start but didn't throw it in the background, so your shell will sit there waiting for output from the start command. Did you see some messages about it listening on port 8080 for the web server and 8021 for the ftp server before that Unix socket message?

When you started it as root the first time, the ownership of the files in <ZopeInstall>/var were changed to the root user.

SiteAccess b0rked my Zope
by Adam Haberlach 31 Jan '02

31 Jan '02

So, last week I was here asking how I could get my virtualhosted intranet to show up correctly (ie, remove the 'intranet' that was getting prepended to the file portion of the absolute URLs). Someone suggested SiteAccess, which looks to be exactly what I needed. I put a SiteRoot object into what I think is the correct place, and now the intranet looks just like it should when I visit. HOWEVER, now when I try to select the intranet's directory in the Zope management interface, it sems to refer me to the root directory instead. All the other ones seem to work correctly. Since I cannot get into the intranet's directory, I cannot remove the SiteRoot rule, or even fix it. Any ideas? -- Adam Haberlach | Who buys an eight-processor machine and then adam(a)newsnipple.com | watches 30 movies on it all at the same time? http://newsnipple.com | Beats me.

Source of error corrections for The Zope Book
by Richard Barrett 31 Jan '02

31 Jan '02

Maybe it is just me but in trying to follow example in The Zope Book I seem to find things that do not match the reality of live Zope - just straight factual errors. Does anyone know whether the authors have published any corrections to the published text in a web accessible form. I've lloked at the PDF version of the book's text but that doesn't seem to be any different to the text on paper. In some cases I have figured out what incantation I should use instead of the one on the printed page but I would be a lot happier seeing some corrected text to confirm my fumbling guesses.

RE: [Zope] adding users
by Joshua Lanza 31 Jan '02

31 Jan '02

I did this by customizing the join_form and register dtml methods in portal_skins, but that would be applicable only if you are using CMF. Otherwise, look at your acl_users folder, and the code that it is using when the Add button is clicked. If you want to do this without an html form, then look at the python source to see the method you need to call, in this case "manage_users". I find this method in User.py --> def manage_users(self,submit=None,REQUEST=None,RESPONSE=None) I believe that you can use something like <dtml-call expr="acl_users.manage_users(...)"> The params for the method can be found in the form fields in the Add User form.

Python/Zope + Alpha/Redhat == Memory Bloat?
by Stefan H. Holek 31 Jan '02

31 Jan '02

I am observing the following phenomenon: Develop a Zope site on Intel/Redhat. Takes about 40MB RAM. Deploy the site on Alpha/Redhat. Contantly grows, easily eating 1GB (!) of RAM until it hits the swap and we restart Zope! All this with the same versions of Python/Zope/Products on Intel and Alpha. I see that with all Zopes (2.3.0-2.4.3) and all Pythons (1.5.2-2.1.2) in all our Projects (and quite different they are). My admins are out of ideas, say they tried everything (different compilers, gcc alpha patches, ...). We also tested Tru64 but could't even get Python going well (lockups, segfaults, out-of-memory conditions). Anybody successfully - that is without obscene memory consumption - running Python/Zope on Alpha processors? Grateful-for-even-the-smallest-hint-ly yours, Stefan
