Subject: [PATCH 2/2] git-svn, perl/Git.pm: extend and use Git->prompt method for querying users
Date: Wed, 28 Dec 2011 01:12:56 +0100	[thread overview]
Message-ID: <4EFA5F08.2060705@tu-clausthal.de> (raw)
In-Reply-To: <7vty4l4rr8.fsf@alter.siamese.dyndns.org>

git-svn reads usernames and other user queries from an interactive
terminal. This cause GUIs (w/o STDIN connected) to hang waiting forever
for git-svn to complete (http://code.google.com/p/tortoisegit/issues/detail?id=967).

This change extends the Git->prompt method, so that it can also be used
for non password queries, and makes use of it instead of using
hand-rolled prompt-response code that only works with the interactive
terminal.
