From: Jim Meyering Date: Mon, 26 Mar 2007 13:57:23 GMT Subject: [PATCH] sha1_file.c (write_sha1_from_fd): Detect close failure. Message-ID: <874po8umyk.fsf@rho.meyering.net> I stumbled across this in the context of the fchmod 0444 patch. At first, I was going to unlink and call error like the two subsequent tests do, but a failed write (above) provokes a "die", so I made this do the same. This is testing for a write failure, after all.
