From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Korsgaard Date: Mon, 26 Feb 2018 23:38:05 +0100 Subject: [Buildroot] [PATCH 2/2] check-host-tar.sh: blacklist tar 1.30+ In-Reply-To: <20180226223805.17496-1-peter@korsgaard.com> References: <20180226223805.17496-1-peter@korsgaard.com> Message-ID: <20180226223805.17496-2-peter@korsgaard.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Tar 1.30 changed the --numeric-owner output for filenames > 100 characters, leading to hash mismatches for the tar archives we create ourselves from git. This is really a fix for a bug in earlier tar versions regarding deterministic output, so it is unlikely to be reverted in later versions. To work around this issue, blacklist tar 1.30+ similar to how we do it for pre-1.17 versions so Buildroot falls back to building host-tar.
