Whitespace in lines property
by Tim Cook 07 Sep '00

07 Sep '00

Can anyone tell me why when I edit a lines property I get leading whitespace inserted? The first line gets seven & each one after that gets 10 spaces. I tried stripping it out but this didn't seem to have any effect. ... <textarea name="alt_names:lines" rows="10" cols="50" > <dtml-in alt_names> <dtml-let cur_item=sequence-item> <dtml-var "_.string.strip(cur_item)"> </dtml-let> </dtml-in> </textarea> ...

supplemental group ids (Linux)
by rugger＠pangea.ca 07 Sep '00

07 Sep '00

I noticed when starting Zope as root (to get privilaged ports), but requesting suid to `nobody' (start -u nobody) the resulting processes have the correct uid and gid, but the supplemental group id list still has the appropriate value for root. This means that the Zope process could, for example, write to files that may belong to root. It's not clear whether this deserves a bug report, so I though I'd ask here instead. The fix is easy (and very lightly tested): 1) grab and install the supplemental gid package (for python) http://www.ccraig.org/software/group.c 2) patch (for 2.2.0) --- z2.py.orig Fri Jun 30 10:23:53 2000 +++ z2.py Mon Sep 4 14:33:51 2000 @@ -682,13 +682,20 @@ if type(UID) == type(""): uid = pwd.getpwnam(UID)[2] gid = pwd.getpwnam(UID)[3] + uname = UID elif type(UID) == type(1): uid = pwd.getpwuid(UID)[2] gid = pwd.getpwuid(UID)[3] + uname = pwd.getpwuid(UID)[1] else: raise KeyError try: if gid is not None: + try: + import group + group.initgroups(uname, gid) + except: + pass try: os.setgid(gid) except OSError:

Major problem involving Multiple zopes on one machine
by Bill Anderson 06 Sep '00

06 Sep '00

This is happening on an HP-UX 11.0 machine. Setup: Two Zope installs, TWO IP adresses. Each install has the -a xx.xx.xx.xx address option passed via the standard start script. problem: occasionally, while working on one, I wind up actually working on the other. Clarification: While in the manage screen for ServerA, I occasionally see the management screen for ServerB. Even wihtout being logged into ServerB. (IE. clean browser session) This sucks. -- Bill Anderson (ARC) Unix/Linux System Administrator HPSO Engineering Productivity Team Wednesday, September 06, 2000 Random Quote: (A)bort, (R)etry, (S)elf-destruct?

DateTime.now().iso_week
by Bill Anderson 06 Sep '00

06 Sep '00

In Zope, I need to get the results of the command in the subject. Unfortunately (and somewhat irritatingly...), Zope doesn't seem to use the mxDateTime package, and thus, _.DateTime does _not_ have it. Anyone know how I would go about getting it? Without using an External method? -- Bill Anderson (ARC) Unix/Linux System Administrator HPSO Engineering Productivity Team Wednesday, September 06, 2000 Random Quote: Why can't women put the toilet seat back up?

INSTANCE_HOME problems...
by Will Dennis 06 Sep '00

06 Sep '00

Hello all, I have followed 4am's INSTANCE-HOME How-To, and have set up a Zope Instance. I created the var, import, Extensions and Products directories from scratch. I then put a new product in the new instance's Products directory. When I start my new Zope instance, it sees all of the products that are installed in the base Zope installation, but not the new product in the instance's Products directory. If I put the new product in the base Zope installation, then my new instance sees it. Based on my understanding of the INSTANCE_HOME How-To, I should be able to have separate products in the instance's Products directory, right? Any help on this is greatly appreciated! If you could, please cc: any responses to my email address (willd(a)p-wave.com) as well as the list, since I am in digest mode. Thanks! BTW, I'm running Zope 2.2.1 on linux2. Thanks again folks, Will Dennis P-Wave, Inc.

Because this is the first > release, remember to make a backup before installing. Looks like ZDebug does not work to well with wizards -- I suspect because of ZCallable. I am using a PTK snapshot from today, latest Zope. Did a test with and w/o ZDebug. Wizard works fine w/o. By the way I like where ZDebug is going! This is what happens when you ad a portal....

Cut down on the Available Objects list.
by Erik Enge 06 Sep '00

06 Sep '00

Hi, all. When I create ZClasses I can make the Available Objects shrink to just a couple of available objects via subclasses and so forth. How would I do this with a Python Class in a Python Zope Product? (Let's say an OFS.Folder.Folder class, which would normally could contain all available objects.) Thanks :-)

Proxy roles don't propagate? - bizzare permissions from ZDChart too
by Brad Clements 06 Sep '00

06 Sep '00

I'm using LoginManager and the loginForm cookie method for security. I want my login form to use the same standard_html_header, stylesheet and so on as my system. My hierarchy is / Strader StyleSheet acl_Users loginForm I've denied anonymous access to Strader and so on, but I want the loginForm to be able to load standard_html_header, which in turn references a few things in Strader Anyway, my loginForm has this: <dtml-with Strader> <dtml-var standard_html_header> </dtml-with> I've given the loginForm a proxy role called "Customer" Customer has full access to Strader and everything in it. It looks like standard_html_header is rendered, but when standard_html_header calls StyleSheet and other objects in the Strader folder, I get the browser login box. Cancelling that shows "access to StyleSheet denied". Its as if the proxy role assigned to loginForm is discarded by standard_html_header, even though I didn't assign standard_html_header any proxy roles. Is this a bug, or by design? -- Also, I see that I have some very strange permissions in my list, looks like an installed product goofed. I see this single character permissions. A C D G Z a d h r s t Ahh.. Looks like ZGDChart hasn't used a tuple where it should...
