[dancer-users] Dancer2 0.166000 - 404 Behaviour Change

[Dave Cross]

Has something changed (deliberately!) in the handling of 404 errors  
between Dancer2 0.165000 and 0.166000?

I have a project that is being tested with Travis-CI. The last test  
that used 0.165000[1] worked fine, but (after a few weeks not working  
on the project) the next test run used 0.166000[2] and failed on two  
tests[3] that generate 404 errors.

I updated my local copy of Dancer2 and found I could reproduce the  
problem in the web app. The problem seemed to be that the app was  
always trying to use views/404.tt (which didn't exist) instead of  
using public/404.html if it can't find views/404.tt - which was the  
old behaviour.

Looking through the Changes file, it seems that it might be related to this:

     * GH #1093, 1095: Use a dynamic TT2 INCLUDE_PATH to allow relative
       views with relative includes; fixing regression introduced by #1037.
       (Russell Jenkins)

But I haven't had time to investigate further.

I've fixed the problem by adding a views/404.tt file to the project.  
But I think that's just a workaround.

I plan to dig a little deeper into the problem later in the week, but  
I thought I'd mention it here first in case anyone had any insights  
that could save me some time.

Cheers,

Dave...
