The only issues you might ever run into would be problems with the 
Python that comes with the OS. But then again if you run Zope in 
production you should never ever use the system Python and build your 
own instead. The system Python tends to be compiled with weird flags on 
RH-based distros to suit their own needs for the many Python-based 
scripts they have in the OS. Don't use it, build your own.


I agree with your opinion, but I have to add that yesterday (that's why 
I follow-up now to this old thread) I had to build python 2.3.5 on a 
shiny new x86_64 machine and it's been a bitch to get right.
Luckily I found the patches in the (mandriva) rpm for 2.3.4 that solved 
(or at least it seems so) the issues with lib/lib64 (there are still a 
couple of tests failing but zope seems to run fine).

the wheel and have a look at

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

Thanks, I'll take a look at it right away. :)

I'm sure Redhat works fine for many people in a lot of  
businesscritical solutions. I'm also sure Redhat is good at what  
they are doing.

All I'm saying is: Redhat didn't work for us. Debian do.
Also RPM didn't work for us, while instaling from source do.
As i remember, redhat 9.0 introduced an error in one of the  
libraries which would cause the server to hang/reboot from time to  
time.

Also we experienced a corrupt RPM database twice. Not fun at all.
Now this may not be redhats fault, but we suffered from it  
nevertheless and gave an impression of redhat's not something we want.


The library error in RH 9.0 was solved very quickly after its  
initial release. Updating the environment once in a while and reading  
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.

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.
Still we dislike Redhat.I think I have written myself way off topic no, so i'll quit here.-- Einar Næss Jensenhttp://einar.nidelven-it.no/einarblog

For the Zope setups the pattern that I have seen most often in larger  
shops is buildout scripts that create self-contained full instances  
with Python, Zope and the instance home. These are easy to set up and  
update with one simple buildout script or Makefile or whatever  
strikes your fancy. This is exactly the same level of  
convenience (and maintainability) as saying rpm -Uvh foo.rpm.  
Obviously this self-contained ZEO client with its own Python could be  
done as a RPM or set of RPMs as well.


The main idea is that you isolate Zope and Python from the rest of  
the system. You can then use simple auto-upgrading schemes like yum  
or even the redhat network to keep everything up to date, while never  
running the risk of influencing or bringing down Zope by making  
unforeseen changes to the Python in use, as could happen with the  
system Python. The same is true for any add-ons you might install  
into the Python used for Zope.

For me that's true with pretty much every single package - apart from  
Zope and the Python that runs it. I would never advocate any strategy  
that leans heavily on the build myself side. That's just insane  
maintenance.


System packages should be used wherever possible (like Apache, etc).  
In cases where you have a better (or purpose-built) replacement for a  
system package then build a package that meshes with your system  
packaging and replaces the original. I've been building my own Squid  
and sometimes Postfix RPMs on many occasions.

 Not sure myself yet. :) There will certainly be a couple of Plone sites

Well, Plone doesn't run on Zope 3, so there ya go. :)

I know it is more convenient to self.compile()  the python, but it  
is always hard to argue with the sysadms on this issue. Our current  
solution is to provide a precomipiled rpm with the pythons we want  
to use.

Why is that the standard os-distributed pythons do not work with  
zope? They seem to work with other python sw...

For the Zope setups the pattern that I have seen most often in larger  
shops is buildout scripts that create self-contained full instances  
with Python, Zope and the instance home. These are easy to set up and  
update with one simple buildout script or Makefile or whatever  
strikes your fancy. This is exactly the same level of  
convenience (and maintainability) as saying rpm -Uvh foo.rpm.  
Obviously this self-contained ZEO client with its own Python could be  
done as a RPM or set of RPMs as well.

The main idea is that you isolate Zope and Python from the rest of  
the system. You can then use simple auto-upgrading schemes like yum  
or even the redhat network to keep everything up to date, while never  
running the risk of influencing or bringing down Zope by making  
unforeseen changes to the Python in use, as could happen with the  
system Python. The same is true for any add-ons you might install  
into the Python used for Zope.

We've been running Zope and Plone built under the OpenPKG.org
portable packaging system for a couple of years now.  The OpenPKG
system avoids problems with vendor python and other packages.

RE: [Zope] Zope 2.8 or 3.1?

2005-10-26 Thread Doyon, Jean-Francois



I'm using Zope 2.7.x on RHEL 3.x without trouble ... Though 
I should be upgrading to CentOS 4.x fairly soon ... what problems have you heard 
of?

As for Zope, if you're not sure, then you probably want 
2.8.x ... 3.1 is stable, but for lower level development ... also depends what 
features you need ... some CMF things aren't avilable in it 
yet.

I think the problems were related to OS software versions
like Python. And most of us don't like rolling our own packages if we don't
have to I'd guess. :) But I've decided to give CentOS 4.2 (or RHEL4U2 in
that language :)) a shot anyway.

Ah ok, well yeah, in my experience it happensthat 
some requirements exceed the version in the distro. Even if they did 
*today*, 6 months from now when another Zope comes out requiring a new python 
version, you'd have to build one yourself anyways.

Might 
as well get used to it now :) It's pretty straight-forward mind 
you.
