8.0 and 9.0 version of Redhat. Things may have improved. Basically the rpms we used were unstable (our site would crash on random acts (or so it seemed to us)), also on a couple of occations installing other rpms (not from redhat though), would break the python from redhat.
This and other bad experiences with redhat/rpms led to a policy with debian and compiled python/zope. I've never looked back.The decision of throwing out redhat and rpms may have been based on my lack of knowledge or incompetence, but I will note that since switching to source-based zope and python (three years or so) and debian we've never experienced any problems that could not be solved within minutes.
Except one: We still have a POSKEY error in our Data.fs introduced with the old rpm-based install. I've never managed to delete or locate the object, but it doesn't seem to cause any trouble. So it stays. Just to remind me never to use redhat or rpms.
Just my two cents.-- Einar Næss Jensenhttp://einar.nidelven-it.no/einarbloghttp://www.homemade.no

Ah yes, well, zope2.6 it was. Otoh, if he would inspect the source

How the bad RPMs you used make you blame RedHat as a whole isn't a  
jump I can follow...  you should be blaming those people who packages  
the RPMs and not the whole distribution.

The "library error" in RH 9.0 was solved very quickly after its

the errata helps, and that's a general issue.


The "corrupt" RPM database problem can be solved very quickly by  
either running the requisite BDB tools against it or blowing it away  
and rebuilding it from scratch.


Debian is a great distribution, no doubt, but "X works for us while Y  
does not" is a misleading statement that creates wrong impressions.  
It's not RedHat's fault that you weren't up to speed on some of these  
things.

You keep it in /usr/local. In fact, when downloading and compiling
python, that's the default place it ends up. And /usr/local/bin
usually is also first in the path, so zopes ./configure script will
find it first.

As i remeber it, a lot of the packages installed software in places where other packages or sourcebased installs would not find it. I think also the up2date procedure with logging in and register your product etc was not what we wanted
Also as I remember it, at about the same time Redhat anounced the end of  life  for  several of its products  and wanted us to use  The new RedHat Enterprise.So there were several factors involved in the change, and probably it didn't have much to do with a bad product from RedHat.

I'm assuming that you are using Ubuntu's 'zope2.7' pacakage, which
actually depends on python2.3.  Check to see whether the startup scripts
for zope actually use /usr/bin/python2.3.

[Zope] LDAPUserFolder proplem

[Krzysztof Kubacki]




I have LDAP database installed on Debian and 2 
Zope-platforms:
    Zope 2.7.6, Plone 2.0.5 
GRUF<3
    Zope 2.8.4, Plone 2.1 GRUF 
3.4
GRUF stands for GroupUserFolder
 
I have installed LDAPUserFolder on both 
Zope-platforms.
I store user in LDAP insted of UserFolder 
everything works fine beside that I can't list members by mean of functions 
which come from portal_membership object.
for instance the codes below won't 
work.
users = 
context.portal_membership.searchForMembers()return 
usersor
users = 
context.portal_membership.listMembers()return users
I have user in LDAP named 'krzysztof' the code 
below works
user = 
context.portal_membership.getMemberByID('krzysztof')return 
user
 
I'm a bit dogged becouse I don't want to recode my 
exists scripts and use other functions(for instance from LDAPUserFolder) to list 
my members.
 
Has somebody the same situation or know what is the 
reason of that?

Most likely he needs to add the CSS:

Has that document been published as I am having a problem with an older
product in Zope 2.8.4.

Can I humbly recommend that you don't reinvent the wheel and have a look at

It's really good for QA and general problem reporting.

Re: [Zope] How do I Create a empty file in a ZClass object?

[Jonathan Cyr]

That seems to be the problem, I find ZClasses to fill a role for 
intermediate skill level developers to create rich objects and 
applications.  The replacement at this difficulty level hasn't appeared 
yet.  My impression is that ZClasses will continue in Zope 2.x, but it 
hasn't been enhanced or touched at all.  The ZClasses implementation 
seems to be solid.  There are shortcomings with ZClasses when you try to 
do too much with them.  Some of the Zope 2 books have nice examples are 
how and what you can do with ZClasses.


That said, I picked up Stephen Richter's book on Zope 3, very nicely 
done... Zope 3 seems to be maturing pretty fast, and some/most of the 
new features have been adapted to the older Zope 2 architecture (a 
project called Five).  If you're going to make a large investment in 
time... and you're just getting started, I'd pick up this book, and see 
if you can handle the difficulty level of Zope 3, at this point.  Zope 3 
technologies seem to be "the New Way".   Although advanced, Zope 3 seems 
to be the result of a lot of self-examination of the triumphs and 
mistakes of Zope 2... a few things I picked out an re-thought 
organization scheme of naming, libraries, etc.,  the use of 
interfaces/contracts Generally cleaner and more pythonic, allowing 
much more power and flexibility... removing much of the mystery of Zope 
2 inner workings and naming conventions.


As for DTML, the old way, DTML is a tag-based way to create web 
interfaces, similar to CFML, PHP, ASP... inline tagging around and 
within the HTML.  The new way, is markedly different, and difficult to 
get your head around at first, called ZPT (Zope Page Templates).  ZPT 
uses XML and an attribute system to embed commands in an HTML page, 
without ruining your ability to use WYSIWYG editors like Dreamweaver, 
etc.  ZPT is highly regarded here on this list, and probably will win 
out in the end.  But there are enough DMTL folks, that DTML will be in 
Zope 3 until ZPT takes over.


There is a Zope 3 mailing list, that might be helpful.

Just my observations and impressions,

-Jon

Thanks a million... it works great...
 
but when you said that ZClasses and DTML are the old way... what is 
the new way... I just started using Zope so I not quiet up to date...


 


would you mind fill me in so I could look it up?

Hey,

As you'll hear shortly, ZClasses & DTML are the old way to do
things, and are not highly recommended, at this point.   Having
said that, I've had success using them.

To Add a ZClass into anything folderish, I've used...



where WWAudioClip was the name of the Product and its ZClass

I place this in a DTML Method that is at the point I wish the
ZClass object to be created, a target if you wish.  Works fine.

This will call the "Add" method in your ZClass.


To Add a regular file object somewhere, I've used..



Parameters Zope ID to be set, Contents (string, whatever), and
Zope Title, and mime-type (optional)

Google "Zope manage_addFile" for more info

HTH,

Jon

Everybody wants to write their own issue tracker (and in the later stages  
of this syndrome, their own project management software), as you are well  
aware of. ;)
