I knew that they *could* bind it;  it just don't understand why anyone
would *want* that feature, given the availability of the other,
non-ambiguous bindings.

I know that I used it intensively in the past (for a former
employer). Now, I almost dropped DTML and with it the DTML namespace
bindung of Python Scripts, although it works as well with
the ZPT namespace...

I would argue that it is a misfeature, especially given the bug which it
surfaces in 'render' / 'call_with_ns'.

I have seen this several times:

  When a bug comes to the surface, a feature is reclassified
  as a misfeature...

I do not need this feature (unlike other reclassified things)
but maybe, fixing the bug is also a solution?

Re: [Zope-dev] Mountpoints

2005-10-19 Thread Tim Peters

[Chris McDonough]
There is a wrinkle about performing this merge that eluded my memory
until now.

To support multidatabases within Zope, it was reasonable to change
ZODB.config.ZODBDatabase to support the heretofore
likely-unused-by-real-world-code databases and database_name options
that may now be passed into ZODB.DB's constructor:

http://svn.zope.org/ZODB/branches/blob-merge-branch/src/ZODB/config.py?rev=38626r1=38574r2=38626

The current blob-merge-branch code depends on this change being
available in the ZODB revision it uses. In case you're interested, the
code that actually makes use of this feature in the zodb-blobs-branch is
in the Zope2.datatypes.DBTab.getDatabase method.

Is this change acceptable for a merge into the ZODB HEAD?

Turns out that a release of Zope3 has already been made that supports
multidatabases, and I'd naturally prefer to follow the lead of a Zope
that's already out there. Jim showed me the Zope3 implementation code
and an example today. I found the code easily (on Zope3 trunk), but
can't for the life of me find anything there that looks like his
example. Jim, where is that?

The Zope3 code in question is in

src/zope/app/appsetup/appsetup.py

function multi_database(). Note that they didn't change any ZODB
files, instead they give values to a DB's .databases and
.database_name attributes after constructing the DB. While that might
be questionable in general cough, the implementation of
multidatabases was meant to be both concrete and public. It's not an
accident that ZODB's tutorial tests/multidb.txt doctest explains and
exploits details of the concrete implementation -- it's not meant to
be abstract. IOW, poking in new values for these attributes isn't
considered to be evil.

I believe (here's where the example I can't find would nail it) they
use the name on a zodb section as the DB's database_name. Fred
points out that ZConfig section names are case-insensitive, forced to
lowercase, so that

zodb CHRIS

and

zodb cHris

have the same name. That's not ideal, and threading these attributes
throughout ZODB's config.py instead (as you did) would be a sane way
to worm around that.

But for right now, I think doing it differently than Zope3 does it
would cause needless confusion more than it would help. Enhancing
Zope3 and Zope 2.9 in the same way(s) here could make sense.

Some mechanics: if we do need to make changes, ya, ZODB trunk is the
place to do it. Work on the branch should use ZODB trunk now. When
that's as ready to go as it's going to get, let me know and I'll make
an internal release of ZODB 3.6 so we can use a ZODB tag before
merging into Zope trunk. (An internal release just means I update
ZODB's NEWS.txt, fiddle version numbers and dates in umpteen places,
and make a tag so other projects can use that -- it's the tag that's
important here; an internal release does not involve making tarballs,
Windows installers, announcements (etc), so it's much cheaper and goes
much faster (minutes vs hours) than making a public release.)

Ok guys.

I'm willing to eat a little crow on this one.  I blame it on being on a lap
top on prone to mucho interruptions (excuse mode off).  The condition for
this was actually more then the response I originally thought.  When a
unauthorized page is accessed on zope.org - you get a 302 to a require_login
script, which in turn does a 302 to the login form.  The below was the
response from the final redirect - not the initial one!  The initial
redirect actually has a cache hitthus the problem was obvious.  The page
which generated the intial redirect was a file system skin, which is cache
policy manager aware - and thus was getting the default policy applied.  As
of now, zope.org caches nothing explicity in the cache policy manager EXCEPT
for .css and .js files.  The squid servers explicitly are configured to NOT
cache pages rendered by zope which do not have explicit cache headers
already set.  So, any further weird caching should be traceable to the
various ram caches and/or httpd accelerated caches in the zope.org site and
not attributable to the framework cache policy or squid itself.


We are caching the release files themselves. I hope.

  The object at %s has an empty or missing  \

 That should help you, I think. All Zope objects that are to be published 
 to the web must have a docstring.

Thanks, but I do have a docstring on the __getitem__ in question.
This error is really starting to annoy me :-/.
If I return a custom object (i.e. a SimpleItem based class instance)
from __getitem__ it works fine, but if I return a PageTemplateFile
instance it screws up.

It is precisely no different from the way you would do it with any other

Is the WingDBG control panel in Zope or in WingIDE?
Where's the code which does this turning off and turning on?


Also, someone mentioned changing the monkey patch to call inherited.


Not sure what you mean by that...


I meant trying to call the inherited/replaced method to do the
work or more of the work rather than completely replacing it.  
This *might* make things less brittle (but I doubt it, actually

;-).


Well, it's more than you may want to call the method you're replacing 
when you're monkey patched method is done doing what it's doing. zdb 
does this with prettymuch all its monkeypatches...


The old/existing impl adds a ##'ed comment block to scripts and 
ends up stripping the block before compiling the script so that
line numbers in the code object don't match up with the copy of 
the script that has the ##'s (which is what anyone reading from 
the file system will see).  The patch changes this to compile

the script w/ the ##'ed comment in place.


Yes, but this stuff isn't necessary ;-)
(and has nothing to do with the code that patches co_filename, right?)


Re: patching Zope + CMF:  It should be possible to patch CMF so
that it can run w/ either patched or unpatched Zope.  The author
of CMFFormController accepted our patch when it was originally
submitted and did that.


Odd. You earlier suggested you wanted to get Zope changed to 
co_filename was meaningful. That change also needs to be made in 
FSPythonScript. That one small change is the only thing I'm talking 
about ;-)



Hmm, so perhaps reworking the patch for CMF to work like that
might help get it accepted... then the question is whether the
Zope patch can be made to work w/ unpatched CMF (if that is an
issue; or is it OK for Zope to change under CMF?).


The two should have nothing to do with each other...


As far as a standard for co_filename it should be the full path
file name for FS scripts (O/W most debuggers won't work out of
the box), 


Well, you see, that doesn't work for me ;-)
(Since I tried both FSPythonScripts and PythonScripts in the same way, 
and that uses their full ZODB path)


We'll try to do actual work on this (rather than sending emailed 
drivel ;-) after Wing 2.0.4 is out.  Unfortunately, we've got 
various things going on that has left us w/ very little extra 
time for the next month or so.


You might start by actually getting to know how zdb works, there's very 
little code in it and it tackles the problem in a different way which 
avoids all the trouble you're getting into above...

I manage a group of users on a Unix system.
They also have an FTP space, and a mailbox (on the system)
They are members of the CPS hosted on the Zope.
They want to change their FTP/POP/IMAP password.

I need to process their request into a batch file.

Obviuosly, ther is the LDAP common authentication for the groupware and

Well, DTML sux for a reason ;)

but dtml-in sequence-item makes no sense unless you have list in list.

You dont need an external method to convert between charsets:

 method which actually returns the image data, sets content
 disposition, 
 etc. All pretty yucky stuff...

Dear friend thank you for your reply.
I have posted another question (as you saw) in order to show that
i am a newbie and did not understand the part of your answer:
 method which actually returns the image data, sets content
 disposition,
 etc. All pretty yucky stuff...
i mean that i have searched how to make this method which actually
returns the image data, sets content disposition but found nothing.
Do you have any reading to sugest about this?

[Zope] inheriting from SimpleUserFolder's User

2005-10-19 Thread Jürgen Herrmann

hello!

i use the SimpleUserFolder product and derive a MyUser class from it's
included User class, which in turn inherits from BasicUser.

the SimpleUserFolder's User class does neither reimplement
getRolesInContext() nor allowed(). i looked at the source of
BasicUser (lib/python/AccessControl/User.py) and found out that
allowed() does not use the information provided by getRolesInContext().
i found this comment:
# Still have not found a match, so check local roles. We do
# this manually rather than call getRolesInContext so that
# we can incur only the overhead required to find a match.

so if i reimplement getRolesInContext() in MyUser, i'll probably also
have to reimplement allowed() to reflect the possibly added local roles,
right?

regards, jürgen herrmann

ps: looking at the code of allowed() i doubt that the manual checking
of local roles will speed this method up a lot: local roles seem to be
a seldomly used feature, the improvement in speed would only occur if
the object in question was protected by a local role (and not a normal
one). is this enough to justify duplicated code with all of it's
disadvantages)?

Looks like you have a None object among your strings in the list.
If so, you can either do:

dtml-if sequence-item dtml-var 
expr=_['sequence-item'].decode('iso-8859-7').encode('utf-8') 

/dtml-if

which is the quick  dirty variant, or:
dtml-var expr=(_['sequence-item'] or 
).decode('iso-8859-7').encode('utf-8') 


Which uses a boolean trick.

I agree with you and i would write this in python script (if this was

There one more thing to solve. Not all my elements in the list are
strings. If i was writing python i would use
for i,elem in enumerate(data):
for j,ele in enumerate(elem):
if isinstance(ele,(str,unicode)):
print unicode(ele,'iso-8859-7').encode('utf-8')
what is the corresponding dtml-if to check if sequence-item is a
string?

THANK YOU VERY MUCH ALLREADY!!!

there is same_type to check. But you could just do:

dtml-var expr=str(_['sequence-item'] or

basically turn everything into a string.

Congratulations, welcome to the zLight ;-)


However, I am curious about the following:
How do you do the equivalent of name=comp.name:records to submit

Well, that works exactly as it did before. That stuff is part of 
Zope's publisher machinery and has nothing to do with DTML or ZPT.


I now realise this after some reading, sorry for the rubbish question.


especially when the initial list is generated dynamically.



Not sure what you mean...


Again irrelevant now;-)

Would you also stop using dtml in zsql methods and do the processing of 
multiple records in python?

It is indeed the 'query' method, which you pass a string with SQL.

It comes from Zope/lib/python/Shared/DC/ZRDB/dbi_db.py, inherited 
through a long path.


You might also look at ExtZSQLMethod.

Actually all third-party userfolders I know of reimplement allowed() in

Calling a DA object gives you a low level connection object (a

safe SQL execution.


From other posts, I understood that you want to do special things.
In such cases, reading the source is necessary -- and being prepared

I follow the recommendation of others to use ZSQL methods...

You should ask Plone related questions on the Plone (and not the
