[2.12.0b1] Redirect exception not handled properly

[Jürgen Herrmann]

running zope 2.12.0b1

Traceback (innermost last):

RuntimeError: http://new-manage.xlhost.local/bliss/logged_out

calling the same script directly works without problems.

What Python version did you use? Considering the exception happens in DT_Raise I suspect something in the realm of exception handling in general, as this changed in both Python 2.5 and 2.6 to some wide degree. Especially that Exceptions now have to be new-style classes and strings don't work anymore.

[Jürgen Herrmann (xlhost)]

i use python 2.4.4 (stock mandriva 2008.1 python)

[Andreas Jung (ajung)]

Unsupported Python version. See

http://docs.zope.org/zope2/releases/2.12/INSTALL.html

[Jürgen Herrmann (xlhost)]

so wtf is all this discussion on zope-dev about dropping python2.4 support about, if it's already deprecated?!

[Lennart Regebro (regebro-gmail)]

That discussion is about Zope Toolkit, while this is Zope 2.

[Andreas Jung (ajung)]

The requirements are as documented . The discussion ist about Zope3 packages - not related to this issue.

Try again with 2.5 or 2.6 and report back.

[Jürgen Herrmann (xlhost)]

ok, i'll try to jump forward to 2.6 now, will take some time...

[Jürgen Herrmann (xlhost)]

after 2 hours of:

- compiling python 2.6.2 freshly from source

- making a new virtualenv for my zope

- installing all non-egg dependencies

- fixing 2.6 related code errors (some non-ascii chars in python files):

the error is 100% the same. good news is my 2.4 site-packages directory was cluttered with all kinds of feculence before, now 2.6' site packages is quite clean :)

[ChrisW (chris-simplistix)]

As I said on the mailing list, the problem here is the "try it" tab NOT the execution of the python scripts.
I've observed this bug myself since Zope 2.12a1...

[Andreas Jung (ajung)]

The issue is caused by

<dtml-else>
  <dtml-raise type="Redirect"><dtml-var URL1></dtml-raise>
</dtml-in>

in dtml/scriptTry.dtml

which is basically DTML turd.

I added an API, 'convertExceptionType', to zExceptions (w/ tests):

 - http://svn.zope.org/Zope/trunk/?rev=99791&view=rev

I then made the <dtml-raise> implementation use the new
'convertExceptionType' API (including tests):

 - http://svn.zope.org/Zope/trunk/?rev=99792&view=rev

The "Try" tab now renders for me properly, even with no params defined
for the script.
