Subject RE: [DISCUSS] What other "features" or code is sitting around that might be suffering from bit rot?
Date Wed, 10 Jul 2013 20:44:24 GMT
Thanks Chip for starting this thread.

I can at least think of the netapp plugin integration as something that was tried before ASF
but no longer tested and used.

I'm all for coming up with this list but I don't see how this list can be conclusive.  The
problem that Edison dealt with in swift support is very real.  I'm not trying to make an excuse
for making a unilateral decision to drop support without getting community feedback first.
 That is wrong and I'm glad it's being resolved.  However, without automated testing backing
functionality, we can have different set of these problems pop up every release.  Should we
start with only functionalities tested in automated testing to be the supported feature set
and add features back in as more testing is added back in? 

To that end, how much of 4.0/4.1/4.2 features are actually added to automated testing?  Or
else we can face the same problem with those features too.

I still support gathering this list, even if it might be inconclusive.
