This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Builds a proxy uri and exports it to the appropriate environment variables. Examples:

ftp://hostname:port

when

scheme = "http", "https", or "ftp"
hostport = hostname:port or scheme://hostname:port
user = username

.guess_internal_locale ⇒ Object

Chef requires an English-language UTF-8 locale to function properly. We attempt to use the ‘locale -a’ command and search through a list of preferences until we find one that we can use. On Ubuntu systems we should find ‘C.UTF-8’ and be able to use that even if there is no English locale on the server, but Mac, Solaris, AIX, etc do not have that locale. We then try to find an English locale and fall back to ‘C’ if we do not. The choice of fallback is pick-your-poison. If we try to do the work to return a non-US UTF-8 locale then we fail inside of providers when things like ‘svn info’ return Japanese and we can’t parse them. OTOH, if we pick ‘C’ then we will blow up on UTF-8 characters. Between the warn we throw and the Encoding exception that ruby will throw it is more obvious what is broken if we drop UTF-8 by default rather than drop English.

If there is no ‘locale -a’ then we return ‘en_US.UTF-8’ since that is the most commonly available English UTF-8 locale. However, all modern POSIXen should support ‘locale -a’.
