[PATCH v3 14/54] tests/qtest: migration-test: Avoid using hardcoded /tmp

Posted by Bin Meng 3 years, 4 months ago

From: Bin Meng <bin.meng@windriver.com>

This case was written to use hardcoded /tmp directory for temporary
files. Update to use g_dir_make_tmp() for a portable implementation.

You need to update the error reporting by using the GError "error" argument
of g_dir_make_tmp().
