From: Shawn O. Pearce Date: Thu, 14 Feb 2008 06:22:19 GMT Subject: [PATCH 1/6] Allow run_command stdout_to_stderr when stderr is a pipe Message-ID: <20080214062219.GA30516@spearce.org> To allow receive-pack hooks to have their stdout and stderr streams redirected to the same pipe we need to setup the pipe on fd 2 before we dup fd 2 over to fd 1. This way we can use a single pipe to capture both stdout and stderr and redirect it to a sideband channel, or elsewhere. Signed-off-by: Shawn O.
