Yeah, I do agree that it makes the code's assumptions a bit easier to

You can download and run the build portion of the coverity tools
yourself. IIRC, that pushes the build up to their servers which then do
the analysis (you can make your own "project", or use the existing "git"
project -- I checked and you are already listed as an admin). I recall
it being a minor pain to get it set up, but not too bad.

Stefan runs it against "pu" on a regular basis, which is where the
emailed results come from. So just having Junio merge it to "pu" would
be enough to get results.

I noticed that they now have some GitHub/Travis integration:


I'm not sure if that is new, or if we just didn't notice it before. ;)
But that probably makes more sense to use than ad-hoc uploading (and
maybe it would make it easy for you to test personal branches, too).
