 Hi
 
 the attached patch to apply to zope/lib/python/OFS/dtml/main.dtml allows
 people who want to use ZShell to type ZShell commands directly from the
 Zope's Management Interface. It should be transparent for people who don't
 want to use ZShell at all.
 
...
 
 As always any comment is very welcome.

Have you thougth of making this a Hotfix instead of patch ?

 Cool, that will mean there will be less worries about Zope users hitting the
 2 gig limit.

But will Zope 2.4.x run on 2.2 ?

 With respect to Python, the issue has been hashed to death over in
 c.l.py and other forums, so I think this will be my last post on the
 subject here.  IMO, the Python 2.0.1 license is the best of all
 possible worlds.  In the words of the FSF themselves:
 
 The License of Python 2.0.1, 2.1.1, and newer versions.

Is there such thing as Python 2.1.1 ? I did'nt find any mention of it on
python.org ?

 However I don't know for sure, because I don't use Java: I use a beautiful

There sure are python programs that run only under windows too ;)

Not that I'd recommend writing them in such a way but it happens, 
especially if they are developed/debugged under windows only and/or use 
windows-specific extensions.

Banning such extensions also seems stupid, as one of main strengths of 
python is its extensibility.

And the fact that you can't use some stackless python features
reasonably 
under plain c-python does not bother me at all.

It would not bother me even if people at Transmeta would make
proprietary 
Crusoe JIT to interpret python bytecodes directly ;) 

I would say that it would make me very glad instead, even if it causes
some 
python programs make wrong assumptions and thus run prohibitively slow 
even on 1.4 GHz Athlons .

  Why? No really. Exactly what do you gain from this? Assuming Zope's
  license becomes GPL compatible, any packages you release you can choose
  to GPL. Why do you think having the GPL is a good thing for the core
  package? Ideological reasons? How does releasing under the GPL make
  the world a better place?

Hopefully Zope will soon be considered a universally available system 
library and this will not matter any more ;)

 For Zope it's not sure, but for Python, as well as for all what people
 usually call open source languages, the license of choice should be
 the GPL, or at least the LGPL, in order for the language in question to
 not become bastardized by some powerful entity.

I see GPL as a good license for GCC and other _compiled_ languages, but 
for an interpreted language GPL or even LGPL could well be viewed as 
forcing _anything_ written in it to be forced under *GPL. Even more 
ridiculous would be the situation where pure python modules can be 
proprietary but  modules written in C must be *GPL (think picle vs
cPicle)

 The problem with plain GPL, as mentionned in my previous message, is that
 this would make a lot of people run away. However the LGPL seems to be a
 very good choice, because this wouldn't allow the core (of Python or Zope)
 to be bastardized with proprietary versions, while still allowing
 proprietary products/extensions to be created.

AFAIK the ability to be bastardized is one of main strengths of
python.
It would be extremely hard to bastardise the main python (as it requires 
you to brainwash Guido), but having proprietary (or open-source)
versions 
that behave in some ways differently, like ZODB-python that has
transactional 
persistency seems to be a feature and not a bug of Python license.

 And yes, a thounsand times yes, I use the GPL for ideological reasons,
 because I really believe this will make the world a better place.

Think global, act local may be a good slogan for software
revolutionaries 
as well ;)

 
 I've thought about the LGPL, and doesn't see any argument against it.
 

I just can't see what LGPL would mean for _whole_ works vs. libraries
(or 
lessers as they are called nowadays ;)

 Hello everyone,
 
 after I got finally frustrated enough with the current implementation of
 the Zope DateTime module, I decided to write a wrapper for mxDateTime. I
 checked the license, and the eGenix Public License is GPL compatible, so
 that we can use it for Zope now.

What does being GPL compatible have to do with Zope ?

Have I missed some licence changes/discussion ?

Does it really exist (the webService behavior for IE) or is it jet

If it does exist, where can I read amout it ?

 Brad,
 
 There are a few COM/COM+ components around that do xml-rpc.
 
 I use them with MS Word to write Word files directly to Zope for instance.
 
 Some are better than others, but ymmv so I'll hesitate to recommend one.
 
 At least one of them is listed on xmlrpc.com.
 
 Having them you could script them via jscript, and basically open up the
 connection easily.

Could you provide a small example ?

I'll probably be needing this functionality quite soon ;)

Does any of them support https ?

 However, purely random IDs would cause all the buckets to be loaded in

 increment sequentially from a random ID and move to a new random ID if
 conflicts ever occur.

Can't one just assign some unique id to each ZEO client and somehow use 
_that_  for making up ids ?

It would have the added benefit of knowing which client made up which
id.

  May be I am misunderstanding your problem here, but are you suggesting that
 
  SELECT tab1.col1 col1, tab2.col1 col2
  FROM ... etc ...
 
  Does not expose 'col1' and 'col2' in the namespace for you? This is not my
  experience. Ok, I only have about 50 ZSQL methods on my intranet but they
  are all complex queries with column naming clashes. If it failed to work as
  you are suggesting, I would not have continued using Zope - Database
  connectivity was one of my criteria.
 
 I mean that:
SELECT tab1.col1, tab2.col1
FROM ... etc ...
 
 Does not expose 'tab1.col1' and 'tab2.col1'.  In otherwords, it
 doesn't gracefully handle name clashes.  I realize that calling out
 the variable 'tab1.col1' out of the namespace is a pain, but
 (hopefully) in the future it would be made easier.

I suspect it is mainly a problem with SQL ;)

amphora2=# select item.item_id, item.ordinal from item where item_id =
15;
 item_id | ordinal 
-+-
  15 |   0
(1 row)

amphora2=# select item.item_type_id, item_type.item_type_id from
item,item_type
amphora2-# where item_id = 15 and item.item_type_id=
item_type.item_type_id;
 item_type_id | item_type_id 
--+--
1 |1
(1 row)

The above example is with postgreSQL, but IIRC it is how the SQL
standard 
defines it to behave.

Except that perhaps it may forbid one from writing such queries if there
is 
a possibility of both item_type_id's not being the same.

[Zope-dev] why is manage_addZSQLMethod unavailable ?

[Hannu Krosing]

Why does this work

dtml-call "_['testadd'].manage_addDTMLMethod('MethodId', 'Method
Title','method text')"


While this does not:

dtml-call "_['testadd'].manage_addZSQLMethod('ZSQLID', 'ZSQL Title',
'DB','','select * from data')"

Error Type: AttributeError
 Error Value: manage_addZSQLMethod

I studies the Znolk product and found that it uses _setObject directly
instead of 
manage_addZSQLMethod .

I was able to overcome it by defining an  one-line external method:

-
from  Products.ZSQLMethods.SQL import *

def manage_addZSQLMethod(self, sqlId, sqlTitle, connection_id, args, command):
self._setObject(sqlId, SQL(sqlId, sqlTitle, connection_id, args, command)) 
-

but it IMHO the visibility of manage_addDTMLMethod and manage_addZSQLMethod 
_should_ be the same ?
