[Zope-dev] Recursion
Hi, I'm writing a python Extension, which searches in any folder recursively. This means the code: def foo(self,counter=None): some code if bar == somewhat: foo(counter=some_int) When i run this through zope a error occours. Zope says expected 1 argument got 0.

[Zope-dev] russian-specific things
Hi! As you maybe know, there are at least _three_ standard encodings for russian cyrillic: koi8-r, which is used in most unices, Windows codepage 1251 and iso8859-5, which is used in some commercial systems (like HPUX). The common workaround for this problem is server-side detection of client OS type. For given OS, web-server decides which encoding is necessary and recodes the document on-fly. Such functionality is implemented as an Apache module which is widely used across russian net. My question is (are you already guessed? good!): (1) is there anybody implemented such thing for Zope? (2) if not, what is the right place to implement such functionality? I mean, what component of Zope should cope whith such things? Zope architecture is not my best, so maybe some of Zope guys can point me?

Option 1 has a problem. If you give it a different name in dtml, e.g.
bar and call it: then self is a reference
to the folder and self.foo doesn't exist. If there is a different method
'foo' in the folder that other method will be called instead.

This one should work as advertised. (Unless you redefine foo in the
python module in which case you get what you deserve).

Can you do a "ps xauww" and mail it to me / the list? Also a "free" would be helpful too. Under linux, shared memory is amongst the last to be scavenged in low memory conditions.

If the test is optional and no value is provided for a variable, or the value provided is an invalid empty string, then no text is inserted. I thought I could just use "optional" with all of my sqltests. select * from course_catalog This works only if I provide at least an empty string for all values.

I have a guesses. I think that the method is working fine, but the nature of HTTP posting is giving you trouble. Remember, a REQUEST typically only contains non-null fields. There are three suggestions on fixing this. 1) preseed the calling form by putting in a BEFORE the form. This way, normal acquisition will get you an empty string even if there is no value entered in the form. 2) A bit more of a pain, but certainly doable. Remember that you can use ordinary logic in a ZSQL method. You can use choose among multiple cases in a single method. But, here you have 16 cases, which is unpleasant. Is it really true that ALL of these can be simultaneosly empty? 3) Considerable more pain, with some loss of safety. Construct the body of your method on the fly. Pass it in as an argument, and call that. For certain forms, this is necessary (if for example the user can modify the form generation process). ___ 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] Setuid code not possible w/new Security API
In previous versions of Zope, it was possible to do "setuid" code by setting AUTHENTICATED_USER to a new user, then resetting when code completed. Zope 2.2 loses this ability, as it has absolutely no API for setting or stacking the "current user", without completely replacing the ZopeSecurityPolicy. This is problematic for things like GUF and GUS which want to execute certain through-the-web objects *as* a particular user. Not as a mask between that user and the current user, but *as* that user, because the object is in the process of finding out what roles the logging-in user has. Currently, it would seem the only way to do this in bounds of the current ZopeSecurityPolicy is to poke into getSecurityManager()._context.user, which seems like a bad idea.
