From b7aa1315198de1bd2c5f457d2e2c6cd007b3f430 Mon Sep 17 00:00:00 2001 From: Nir Soffer Date: Wed, 1 Feb 2017 02:31:18 +0200 Subject: qemu-io: Return non-zero exit code on failure The result of openfile was not checked, leading to failure deep in the actual command with confusing error message, and exiting with exit code 0. Here is a simple example - trying to read with the wrong format: $ touch file $ qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $? can't open device file: Image is not in qcow2 format no file open, try 'help open' 0 With this patch, we fail earlier with exit code 1: $ ./qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $? can't open device file: Image is not in qcow2 format 1 Failing earlier, we don't log this error now: no file open, try 'help open' But some tests expected it; the line was removed from the test output.
