/swift/common/utils.py >> whatremyips' output dependent on system locale

[Allaedine El Banna]

This is not a major bug, but if you try for example the French locale for your system on an Ubuntu 10.10, fr_FR.UTF8, you will notice that the output of the command /sbin/ifconfig is something like :

..."inet adr"...

instead of

... "inet addr"...

like the function common/utils.py/whataremyips() is waiting for.

I suggest another way to find the ip address of the machine.

This bug implies that you are forced to use English Locales to run Swift. Else, replicators cannot start for example.

I just spent a few minutes reminding myself why we don't get this information from the system more directly, and the answer is it's pretty freakin' hairy.

I bet we could just pass that popen call an env with LC_ALL=C or POSIX or whatever locale is always there. I'll look into it later today.

The command "ip" is both non-locale sensitive and non-hirsute. Try "ip -o -f inet addr show dev eth0"

[Ewan Mellor (ewanmellor)]

Thanks, Launchpad, for word-wrapping that so well. That's

ip -o -f inet addr show dev eth0

Same kind of bug on Nova side: see bug 691044

Another option would be using netifaces package.

That seems like the best solution. I want to run the new dependency by a few core devs first, and there are a couple of things that will need to change for pep8 (camelCase and the blank line above the import).
