[bitbake-devel] bb.utils.vercmp() not consistent with debian rules

[Lu, Lianhao]

Hi guys,

When I'm looking at the Yocto bug#2233, I find that the function bb.utils.vercmp() is not consistent with the debian packaging rules(http://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version). 

According to debian rules, "r0" is earlier than "r0-dream", but the bb.utils.vercmp() thinks "r0" is later than "r0-dream".

A pervious patch http://cgit.openembedded.org/bitbake/commit/?id=727ce6ffe33a119cb17f7d91b173f11a055eea3c seems causing the bb.utils.vercmp to specially handle the separators of "." and "-". 

Is it desired to behave differently from debian rules?
