From 3e323d8ee067c418c592ebd5e3a6271d18422296 Mon Sep 17 00:00:00 2001 From: Scott Moser Date: Fri, 20 Jan 2012 08:44:45 -0500 Subject: in netinfo output (ci-info:), fill in empty fields with a "." If you were trying to parse this output with something, an empty field would be difficult to handle, as you'd have to know the expected lengths of each field. The '.' means empty, but then all fields are non-whitespace delimited by one or more whitespace. --- cloudinit/netinfo.py | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) (limited to 'cloudinit') diff --git a/cloudinit/netinfo.py b/cloudinit/netinfo.py index be7ed3a9..80223256 100644 --- a/cloudinit/netinfo.py +++ b/cloudinit/netinfo.py @@ -22,7 +22,7 @@ import subprocess -def netdev_info(): +def netdev_info(empty=""): fields = ("hwaddr", "addr", "bcast", "mask") ifcfg_out = str(subprocess.check_output(["ifconfig", "-a"])) devs = {} @@ -59,6 +59,13 @@ def netdev_info(): pass elif toks[i].startswith("%s:" % field): devs[curdev][target] = toks[i][len(field) + 1:] + + if empty != "": + for (devname, dev) in devs.iteritems(): + for field in dev: + if dev[field] == "": + dev[field] = empty + return(devs) @@ -85,7 +92,7 @@ def getgateway(): def debug_info(pre="ci-info: "): lines = [] try: - netdev = netdev_info() + netdev = netdev_info(empty=".") except Exception: lines.append("netdev_info failed!") netdev = {} -- cgit v1.2.3
