The final release of 1.6 has some bugs that seriously interfere with
Zope. The current CVS of python 2.0 is much more stable than the final
release of 1.6

There are some minor compatability issues in Zope - I document
everything I know with my Unicode patches (which requires 2.0) at
http://www.zope.org/Members/htrd/wstring/Unicode0.4Readme.txt

I've seen some people report using 1.6 successfully with Zope - 
at this point I can't recommend doing that for a *production* 
site, since while it may *work* we still need to assess some 
things regarding their impact on security.

I 100% agree with Brians caution here, however

For example in 1.6 strings have methods, which may or may not 
have an impact on DTML safety. This is also the case for 
Python 2.0.

string methods are safely inaccessible as of the new security
implementation in 2.2 (hurrah for private-by-default)

Stick with 1.5.2 or beware the pitfalls.

Hi Jon,

at this point I can't recommend doing that for a *production* 
site, since while it may *work* we still need to assess some 
things regarding their impact on security.

According to Guido van Rossum in 

http://linuxtoday.com/news_story.php3?ltsn=2000-09-07-011-21-OS-CY-SW
 
you are not able to use GPL'ed Zope products with Python 1.6
(or 2.0) until the dispute is settled.  

| GVR: It should be clear by now that the future of the Python license
| is not in my hands (nor in BeOpen's hands) but in the hands of CNRI
| and Richard Stallman. If they can't agree on changes to the 1.6
| license or a different interpretation of GPL compatibility by the FSF,
| the final release of Python 2.0 (planned for early October) will be
| incompatible with the GPL. Stallman has already mentioned that in that
| case he will attempt to maintain a GPL-compatible fork of Python,
| probably based on version 1.5.2. This would be a great waste of time
| for all, but I can't stop him. 

Well, possibly we'll lose the GPL'ed Zope components this way. 

Cheers,
Nils

No copyright-based licence whatsoever, including but not limited to the GPL, ZPL, and 
the licence on
Microsoft Word, can ever prevent you from *using* any software you like, in any 
combination.

They can only constrain *distribution* of that software and derived works.  This is a 
serious
problem for software authors, but not for people running Zope-based sites.

Re: [Zope] zope 2.2.1 and python 1.6

2000-09-13 Thread Nils Kassube

Guten Abend.

I recalled (?) my mail within a few minutes after sending. It
didn't yet appear on the mailing list. Too bad you can't 
cancel a mail like a Usenet posting.

 They can only constrain *distribution* of that software and derived
 works.  This is a serious problem for software authors, but not for
 people running Zope-based sites.

I think a lot of the people running Zope sites are developing
software too. If you use e.g. ZSQL methods and DTML to connect
to a database, you _are_ a software author. Website development
in Zope is actually programming. 

Well, but now it's time for the big soccer match in Hamburg =:-

Cheers,
Nils

I wrote a lot of nonsense:

 (or 2.0) until the dispute is settled.  

This is WRONG. Of course it is possible to use GPL'ed software
with less restrictive licensed programs. 

Must be the starting alcohol intoxication because of the Hamburg 
vs Juventus Turin game in the Champions League :-)  

Prosit, 
Nils
