I guess you are just talking about IFAwareObjectManager, not about 
WriteLockInterface and PluggableIndexInterface.


You might want to grep through CMF 1.6 or CMF 2.0 to adjust your

Wichert, can you quantify about to hit the streets? I would assume  
for a Plone alpha a PAS beta is perfectly fine, and that could be cut

appropriate, and that gives us time to work the collector a bit.

Re: [Zope] Can Zope 2.9 Coexist With Zope 2.6 Using Different Ports?

2006-02-23 Thread Thomas Bennett
I'm running Zope 2.8.1-final, python 2.3.5, linux2 and  Zope 2.6.1 python 
2.1.3, linux2 on the same server so I don't see why you cant' also run Zope 
2.9.  More than likely each of your configurations have the same path to the 
lock file.  Edit zopefolder/etc/zope.conf where zopefolder is the name of you 
Zope instance.  Or you need to grant permissions for the user that Zope runs 
as to modify that file or change owner.  See 'man chmod' and 'man chown'. 

from zope.conf

# Directive: lock-filename
#
# Description:
# The path to a lock file which will be locked by Zope while it's
# running.  This file is used by zopectl.py to determine if Zope is
# currently running.  This defaults to CLIENT_HOME/Z2.lock.

How do you want to use the debugger? I run the tests, if the set_trace()

There used to be an issue with the debugger not displaying anything, since

Re: [Zope3-Users] Re: [Zope] Debugging doctests

2006-02-23 Thread Chris McDonough
I dunno about sucking because they are quite good for documentation,  
but I tend to write plain-old unittests instead of doctests when I'm  
testing without any pretense towards writing documentation.  If you  
test internals of a class in a doctest, the doctest body gets pretty  
cluttered, which tends to defeat the documentation-esque-ness of them.


Being able to set a breakpoint in the test body is important for me  
too.  I probably could be setting breakpoints once I'm in the  
debugger, but it's often easier to just stuff in a pdb.set_trace()  
before the line of code that I want to examine.   And putting a set  
trace in a unittest is a natural thing to do, because you know the  
set trace will only get invoked once during a test run (as opposed to  
putting it right in the app code, where it might get invoked by  
accident through a different test).  Setting breakpoints in unittest- 
tests is typically more fruitful than putting them in doctest-tests  
for the reasons that have been talked about in this thread.

 debugger

Well, how do you set a breakpoint in something which has no py-file
and line, but is in a text-document or string? :-)

Not to mention, doctests are not debuggable from WingIDE. ;-)

Are you talking about doctests in docstrings?  If so, I definitely  
see downsides to that use case.  I was talking about doctests in  
stand-alone text files.  That's my (and several others) preferred  
way of using them.


Either.



If you /were/ talking about stand-alone doctests, then I have no  
idea what you're talking about. :)


It's just opinion, but for example, I don't think zope/wfmc/xpdl.txt  
reads much better as a doctest than it would as a plain old  
unittest.  But it's of course a judgment call.

Perhaps this is just one of those to-each-his-own things. shrug   
My own are doctests. ;)


Sure.  I actually really appreciate reading good doctests, they help  
a lot, and they beat not having any docs at all any day!


A non-sequitur:  For truly standalone packages, I suspect that people  
expect some form of non-executable narrative documentation to be  
included that ties the continued use of the package together with its  
implementation.  In my experience, it's easy to get lured into  
thinking that you've documented a package properly because it has  
doctests and interface documentation, when in reality it probably  
needs some other form of documentation beyond the doctests (e.g. high- 
level overview of purpose, how to install it, what other packages it  
depends upon, which versions of Python/Zope it works with, who is  
responsible for maintaining the package, where to report bugs, and so  
on).  I suppose this is really a packaging issue, but it would be  
nice if more packages in the  zope namespace package were treated as  
islands like this that could be installed separately from Zope  
proper.  It would also likely help prevent inappropriate dependencies  
from creeping in.  Zope 2 wasn't born a mess of spaghetti  
dependencies, they just sort of grew like weeds over time.

Maybe we should have a WingIDE sprint in Boston at some point. This would be a

The ZSCP tries to exactly capture this information and provide it via its 
site.

So, I take it that you are a second voter in favor of not requiring all tests 
to be doctests.

If the ZSCP thing takes off, I think test/doc req'ts should be  
somewhat looser than mandating a particular test/doc framework  
(something along the lines of must have good test coverage and  
appropriate narrative documentation, maybe with examples of what  
this means that could be in doctest format by default).  Would that  
be acceptable?

I have already working parsers and writers for all file formats. I have also a 
preliminary (but tested) implementation of registering, managing, 
unregistering a package in the repository with the ZSCP.

Kamal Gill has agreed to do some initial artwork for the site, which should be 
done mid-March.

We will see how it proceeds. Roger suggested to maybe even do some of the work 
during the Swiss Eastern Spring.

Re: [Zope] Zope scheduling problem

2006-02-23 Thread Nicholas Watmough

Thanks for that. It worked perfectly.

Out of interest, why am I unable to access the method from with my Zope 
python code? What is a private object, and why is it private?


Thanks,

Nick

How do I change the permissions so I can access this method?



You can't, but you can access the method from unrestricted code.
Unrestricted code is any python code not stored in a Python Script or
a Pagetemplate object. An External Method or a code part of a Zope
Product would do the trick.

[Zope] Using ReStructuredText instead of StructuredDocument inside ZPT

2006-02-23 Thread John Schinnerer
Hello,

I have been using the Structured Document (SD) product with page
templates (to provide some content sections that a client can edit
using structured text).

Now I would like to use ReStructuredText Document (RSTD) instead of SD.

I have been using code like this in a page template to render the
content of a SD within the page template:

...
div metal:fill-slot=pagebody

p tal:content=structure container/client_content/vision_statement
Vision Statement
/p

/div !-- end of page body slot --
...

...where vision_statement is a SD object.

I expected that this would work the same if vision_statement were a
RSTD object...however it does not.  
What displays is only the unrendered, plain text content of the RSTD.

Can I use a RSTD object in the same way I have been using a SD?

If so, how do I get it to render?

This is on zope 2.7.5 with the ZReST that comes built in.
A RSTD called directly (instead of inside a ZPT as above) renders as
expected.

thanks,
John S.
