From 3190683ea322f2c779b85b3f8f59b2f11bdacb2e Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Sun, 2 Jul 2017 17:05:09 +0200 Subject: [PATCH] iotests: Use absolute paths for executables A user may specify a relative path for accessing qemu, qemu-img, etc. through environment variables ($QEMU_PROG and friends) or a symlink. If a test decides to change its working directory, relative paths will cease to work, however. Work around this by making all of the paths to programs that should undergo testing absolute. Besides "realpath", we also have to use "type -p" to support programs in $PATH. As a side effect, this fixes specifying these programs as symlinks for out-of-tree builds: Before, you would have to create two symlinks, one in the build and one in the source tree (the first one for common.config to find, the second one for the iotest to use). Now it is sufficient to create one in the build tree because common.config will resolve it.
