Subject: net: don't throw on net.Server.close()
X-Git-Tag: upstream/0.12.0~205
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f1dc55d7018e2669550a8be2c5b6c091da616483;p=platform%2Fupstream%2Fnodejs.git

net: don't throw on net.Server.close()

When close() is called on a non-listening server, a synchronous
error is thrown. This commit causes the error to be passed to
the asynchronous callback function instead.
