From 3b4494c586574b59d80d0f1b88bd4c3d56b678cf Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sun, 3 Jul 2016 09:32:44 +0200 Subject: [PATCH] merge-recursive: flush output buffer even when erroring out Ever since 66a155b (Enable output buffering in merge-recursive., 2007-01-14), we had a problem: When the merge failed in a fatal way, all regular output was swallowed because we called die() and did not get a chance to drain the output buffers. To fix this, several modifications were necessary: - we needed to stop die()ing, to give callers a chance to do something when an error occurred (in this case, flush the output buffers), - we needed to delay printing the error message so that the caller can print the buffered output before that, and - we needed to make sure that the output buffers are flushed even when the return value indicates an error. The first two changes were introduced through earlier commits in this patch series, and this commit addresses the third one.
