From 6b3fa7e7d13a3c8fddba43ad6e8acb314d1985ac Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Tue, 9 Feb 2010 18:01:29 -0800 Subject: [PATCH 1/2] t5401: Use a bare repository for the remote peer We want to avoid the warnings (or later, test failures) about updating the current branch. It was never my intention to have this test deal with a repository with a working directory, and it is a very old bug that the test even used a non-bare repository for the remote side of the push operations. This fixes the interleaved output error we were seeing as a test failure by avoiding the giant warning message we were getting back about updating the current branch being risky. Its not a real fix, but is something we should do no matter what, because the behavior will change in the future to reject, and the test would break at that time. Signed-off-by: Shawn O.

Pearce" Date: Wed, 10 Feb 2010 09:34:12 -0800 Subject: [PATCH 2/2] receive-pack: Send internal errors over side-band #2 If the client has requested side-band-64k capability, send any of the internal error or warning messages in the muxed side-band stream using the same band as our hook output, band #2. By putting everything in one stream we ensure all messages are processed by the side-band demuxer, avoiding interleaving between our own stderr and the side-band demuxer's stderr buffers.
