[Gluster-devel] Performance Translators' Stability and Usefulness

Hi Filipe,
   I think if the GlusterFS devs actually implement the QA process they've 
(allegedly) had since September last year, that would go a long way to 
improving stability and reliability across the whole application.

   If the QA process as described on the Wiki was actually implemented, we 
would most likely not see two critical data corruption bugs in two 
consecutive major releases, and functionality like DHT and AFR that has been 
around for years might have a chance of working as described.

   As much as I would like to see features like active self-heal and non-stop 
I/O, perhaps it's time for a GlusterFS feature freeze.

   During this freeze they could do a proper human-eyeballs-on-code style code 
review and get their QA processes and testing frameworks developed properly. 
In doing so, hopefully provide us with the kind of reliability and stability 
that we should see in a piece of software with the 2.x tag.

   Heck, maybe they could even submit their project to Coverity for analysis, 
like I've suggested before. It *is* free for open source projects, and the 
results come highly regarded.
