[Zope-dev] REQUEST.AUTHENTICATED_USER question

2002-01-20 Thread vio 

Hi,
Does anybody know what is the method call to modify the AUTHENTICATED_USER attribute? 
I am unable to trace where REQUEST feeds data for its AUTHENTICATED_USER attribute.

Some context to my question: I am using a custom method to authenticate users coming 
to my site. So when the user logs in, he is 'Anonymous User' (from call: 
AUTHENTICATED_USER.getUserName()). But after his login name and password checked ok, 
how do I switch his identity in Zope from 'Anonymous User' to his/her new identity?  
What I am looking for is that next time I call 
'REQUEST.AUTHENTICATED_USER.getUserName()' to get the new UserName he just logged in 
as, not 'Anonymous User' again.

Examining CookieCrumbler.py source, this authentication product uses the 
'before_publishing_traverse hook' mechanism. But isn't there a simpler way to do this 
than modifying REQUEST.RESPONSE at each traversal? Sounds like a lot of overhead.

Vio

[Zope-dev] ExternalFile released

2002-01-20 Thread Craeg K. Strong 

In case any of you hadn't seen it yet, here is the news item
I just posted on zope.org:


ExternalFile 0.8 Released (Stable)

Created by arielpartners http://www.zope.org/Members/arielpartners on 
2002/01/17.

This is the second public release of our ExternalFile 
http://www.zope.org/Members/arielpartners/ExternalFile product.
Why not simply use ExtFile 
http://www.zope.org/Members/MacGregor/ExtFile? Because ExternalFile 
supports pointing to a file in situ like a symbolic link, rather than 
copying it into some central repository directory.

This may not seem like a big deal, until you consider that those files 
might be stored in a revision control system like CVS. ExternalFile 
gives you the ability to create a Zope object that points to a file in, 
for example, a CVS sandbox for its content.

This new release adds workalike capabilities. ExternalFile can now 
behave like any of the following:

* DTMLDocument
* DTMLMethod
* Image

ExternalFile is usable by itself. It is also the base class for CVSFile, 
to be released shortly.

[Zope-dev] Core dumps - How to find out the bug?

2002-01-20 Thread Dario Lopez-Kästen 

Hello!

I wonder what to do when zope coredumps?

I have been given the advice to hook up gdb to zope/python and see what
happens, but there are two problems with this:

1) I barely know gdb at all, let alone know how to hook it up to a running
process
2) The dumps happen at random (last one happened at 3 in the morning when a
co-worker was working from home).

I only have core dumps to work from. I include the stack from latest core
dump.

I am using python 2.1.2 (release), Zope2.4.3 release, RedHat Linux 7.2.
Python is compiled --without-pymalloc

What can I do more to track this down?

Thanks,

/dario
