From 9086c7639822b6e96aa93192917bf036e1345b1d Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 16 Feb 2022 13:54:54 +0100 Subject: [PATCH] tests/qemu-iotests: Rework the checks and spots using GNU sed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of failing the iotests if GNU sed is not available (or skipping them completely in the check-block.sh script), it would be better to simply skip the bash-based tests that rely on GNU sed, so that the other tests could still be run. Thus we now explicitely use "gsed" (either as direct program or as a wrapper around "sed" if it's the GNU version) in the spots that rely on the GNU sed behavior. Statements that use the "-r" parameter of sed have been switched to use "-E" instead, since this switch is supported by all sed versions on our supported build hosts (most also support "-r", but macOS' sed only supports "-E"). With all these changes in place, we then can also remove the sed checks from the check-block.sh script, so that "make check-block" can now be run on systems without GNU sed, too.
