[Zope-dev] ZPatterns: SkinScript semantics
In a SkinScript COMPUTE statement, should I be allowed to supply different names in the OTHERWISE LET section as in the attributes section? For example: WITH some_query() COMPUTE foo,bar,baz OTHERWISE LET foo='There is no foo', spoon='There is no spoon' Looking at the ZPatterns code, I don't think this attribute provider will get registered for providing "spoon", although "spoon" will get calculated if foo, bar or baz is requested. On the other hand, you could consider the above as a shorthand for: WITH some_query() COMPUTE foo,bar,baz, spoon=NOT_FOUND OTHERWISE LET foo='There is no foo', spoon='There is no spoon' In which case, it works entirely as expected. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] ZPatterns patches
I've put an extensive patch to ZPatterns 0-4-3b2 here: http://www.cat-box.net/steve/ZPatterns.patch The patch includes the following: * Fix to _memento class so it works with Zope 2.3 * Alteration to GAPMixin so the the attributes it says it provides come from the union of the assignments and the defaults. * Add style="width: 100%;" to SkinScript edit textarea, in line with other zope textareas. * Add syntax to SkinScript "INVALIDATE FOR". You can put an optional invalidate-for clause at the end of a compute statement. This causes the attributes provided by the statement to be invalidated from the dataskin's attribute cache when any of the attributes named after INVALIDATE FOR change. It is easier to demonstrate than to explain :-) There's also an updated PlugIns/www/main.dtml file at: http://www.cat-box.net/steve/main.dtml An example of the new SkinScript syntax: WITH SELF COMPUTE name='%s %s' % (forename, surname) INVALIDATE FOR forename, surname This is useful if you're providing attributes from another DataSkin. Here's an example from some school management software. This is an attribute provider for Pupils. A Pupil may have an Instructor. This is implemented by the attribute instructor_id of Pupil. # the instructor is only valid if the pupil is current WITH SELF COMPUTE has_instructor=instructor_id or 0 and current and 1 # don't use has_instructor below, or the instructor details for # cataloging won't get updated when the assigned instructor changes # from no instructor to having an instructor. WITH self.instructor_id and self.current and Instructors.getItem(self.instructor_id) or NOT_FOUND COMPUTE instructor_name=name, instructor_name_link='a href="%s"%s/a' % (absolute_url(), html_quote(name)), instructor_sort_key=sort_key, instructor=RESULT OTHERWISE LET instructor_name='no instructor', instructor_name_link='no instructor', instructor_sort_key='', instructor=_.None The problem here is that I can't use has_instructor in the WITH clause, if I'm also using has_instructor in the same transaction as I'm updating instructor_id. I have to use "self.instructor_id and self.current" instead, as above. However, with the new syntax, I don't have to worry about that: # the instructor is only valid if the pupil is current WITH SELF COMPUTE has_instructor=instructor_id or 0 and current and 1 INVALIDATE FOR current, instructor_id WITH has_instructor and Instructors.getItem(self.instructor_id) or NOT_FOUND COMPUTE instructor_name=name, instructor_name_link='a href="%s"%s/a' % (absolute_url(), html_quote(name)), instructor_sort_key=sort_key, instructor=RESULT OTHERWISE LET instructor_name='no instructor', instructor_name_link='no instructor', instructor_sort_key='', instructor=_.None Thanks to PJE for pointing me in the right direction on how to implement this. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] Added rename to ZOPE FTP server
Hi, I've added the rename capability to the Zope FTP-server, so I could use the KDE FTP client (this is a known Zope bug). I attached the 3 modified files (from the 2.2.5 src distro). There is however another problem in the ZOPE ftpd which is probably not related to my patches, but for which I have not found the cause. The SIZE command (used by the KDE ftp-client as a kind of file-exists probe) reports the size of identical named objects higher in the tree, to reproduce: copy with the KDE FTP client a directory tree which has fileabc in the top directory and a file "fileabc" in a subdirectory to the Zope ftp server. The SIZE command returns a size (for a non existing object!) but the LIST command works o.k.

[Zope-dev] Better test case for Bug 1783: Persistent __call_method__() interferes with __getstate__
Hello all,
The following is the best test case I have so far for bug 1783.
The behavior of the bug is that no CMethods from Persistent can be
called indirectly when the __call_method__ hook is present. This means
that I can't override any of __getstate__, __setstate__, _p_deactivate.
#!/usr/bin/python
import ZODB
from Persistence import Persistent
class P(Persistent):
def __call_method__(self, meth, methArgs, methKW={}):
return apply(meth, methArgs, methKW)
p = P()
p.__getstate__()
#This throws exception!
Persistent.__getstate__(p)
TypeError: function requires exactly 0 arguments; 1 given

With cookie based auth being the default unless they don't have cookies (either because they have them turned off, behind a proxy filter, etc), in which case they should use basic auth. The problem is I'm not sure how to get it to use something other than cookie based auth. The default setup tries to use cookie auth whether or not cookies are in use. Any tips on how to get this working? I know there is no great way of detecting cookies, besides setting one and testing for it. But even if I did this, how do I say I want basic auth if the test cookie isn't found. Doing a: raise "Unauthorized" or RESPONSE.setStatus(401) will tell the browser to pop up an authorization dialog. Note that if you do this, you won't be able to also display a login form for cookies. For all practical purposes, you need a seperate login page for cookies vs. basic auth. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
