commit 93c9edbef51b31056f93a37a778326c90a83158c Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> AuthorDate: Tue Jun 15 16:02:29 2021 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Fri Jul 9 16:38:27 2021 +0100 tests/xenstore: Rework Makefile In particular, fill in the install/uninstall rules so this test can be packaged to be automated sensibly. This causes the code to be noticed by CI, which objects as follows: test-xenstore.c: In function 'main': test-xenstore.c:486:5: error: ignoring return value of 'asprintf', declared with attribute warn_unused_result [-Werror=unused-result] asprintf(&path, "%s/%u", TEST_PATH, getpid()); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Address the CI failure by checking the asprintf() return value and exiting. Rename xs-test to test-xenstore to be consistent with other tests. Honour APPEND_FLAGS too.
