[PATCH 7/8] git-remote-testpy: don't do unbuffered text I/O

From: John Keeping <john@keeping.me.uk>
Date: Jan 12, 2013, 19:23 UTC
Message-ID: <d6f040809ad7457ff5f97fb23a2531988938a96a.1358018078.git.john@keeping.me.uk>
In-Reply-To: <cover.1358018078.git.john@keeping.me.uk>

Python 3 forbids unbuffered I/O in text mode. Change the reading of stdin in git-remote-testpy so that we read the lines as bytes and then decode them a line at a time.

This allows us to keep the I/O unbuffered in order to avoid reintroducing the bug fixed by commit 7fb8e16 (git-remote-testgit: fix race when spawning fast-import).
