Issues with SDK hostname

Platform Development
#1

I’ve found two issues with latest SDK using docker (probably vbox version has same issue):

if you add device with hostname i.e. “Zenfone5z” it will make it lowercase “zenfone5z” and it won’t connect.

second issue is missing host search parameter in /etc/resolv.conf making lan hostname resolution not working and you need to use FQDN

#2

RFC1178 gives:

Don’t expect case to be preserved.

     Upper and lowercase characters look the same to a great deal of
     internet software, often under the assumption that it is doing
     you a favor.  It may seem appropriate to capitalize a name the
     same way you might do it in English, but convention dictates
     that computer names appear all lowercase.  (And it saves
     holding down the shift key.)

I wouldn’t blame the SDK for normalizing the name, but rather whatever software fails to actually look it up. Or possibly the configuration thereof; perhaps it expects or works best with lowercase entries.

DNS in general should be case-insensitive with lowercase as the normal representation (RFC952, RFC4343 etc).

#3

And also guess who set hostname to be uppercase? that’s right it was jolla and their hardware sdk

#4

While not particularly nice, it is still the resolver that is failing the hardest. Lookup should not be case-sensitive.
My Xperia 10 calls itself Sailfish, but i have no issue resolving either sailfish or Sailfish, be it from docker or the regular shell.
