GETINFO response parser doesn't handle AF_UNIX entries.

torbutton issues a GETINFO command to validate the configured socks port, but the response parser doesn't handle AF_UNIX entries.

[07-21 19:17:44] Torbutton WARN: unexpected tor response: net/listeners/socks="127.0.0.1:9050" "unix:/var/run/tor/socks"

This currently doesn't matter because the number of people using an AF_UNIX capable Tor Browser is ~1, but it is something to note for the future sandboxing efforts.

Whoops, the command that's puking is GETINFO, not PROTOCOLINFO.

Kathy and I decided to begin our UNIX domain socket journey by fixing this bug. Here is a patch: https://gitweb.torproject.org/user/brade/torbutton.git/commit/?h=bug19733-01&id=db21620ac199bd4bc25939f14c6caaaa44093b89

Mozilla changed their implementation to use file: URLs instead of simple paths (see https://bugzilla.mozilla.org/show_bug.cgi?id=1211567#c22). We will revise this patch accordingly.

I would suggest using === (triple equals) for safety.

Done.

{{{

• foundSocksListener = (socketPath == path); }}} {{{

•      foundSocksListener = ((socksAddr == torSocksAddr) &&

•                            (socksPort == torSocksPort));

}}} I would suggest using === (triple equals) for safety.

OK. We fixed another place too where == was used instead of ===. While testing, we discovered that file: URLs that begin with file:/// were not handled correctly (and they should begin that way). So we rewrote the code that converts the network.proxy.socks value to a file path.

Looks good with one nit: I guess removing the very first line in torbutton.js is just an oversight? I think we should keep that one. :)
