Description

Every time a TracError is instantiated, Python 2.6 raises a DeprecationWarning because direct access to the message attribute is considered deprecated: 

.../trac_0.11dev/trac/core.py:36: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
    self.message = message

jonas already fixed that for 0.11.1 IIRC, then reverted the fix. What was the reason again?

comment:2 by kamil@…, 15 years ago

I can confirm this on openSUSE 11.1 with Trac 0.11.4

comment:5 by osimons, 15 years ago

Just spotted some advice from Brett Cannon suggesting using a property in order to keep the deprecated 'message' when subclassing Exception. Tested a quick patch that seems to work for 2.4 and 2.6.

I suppose I can look after this one. Testing welcome.

comment:7 by Christian Boos, 15 years ago

Using lambdas could make it a one liner.

comment:8 by Christian Boos, 15 years ago

(or two ;-) )

But otherwise, looks good.

Replying to cboos:

Really? I actually tried that before submitting the patch, but I got an error saying it would not allow assignment in lambda. I just thought 'hmm' and reverted back to the explicit version. Are you sure? Could well be my mistake, of course :-)

Indeed, but think functional ;-)

Milestone: 0.11.6 → 0.11.5

Ah, I see. Looks like we have a clear winner in this round of "Know-Your-Python"…

Thanks, committed in [8333:8334].

FWIW, I still find the non-setattr setter clearer. Not that it really matters…
