To be more specific - following use cases are checked: - If the read interval is correct - If the proper ABI is used - to check if adjacent data is not overwritten Reviewed-by: Adhemerval Zanella --- Changes for v2: - Move test execution from tests to xtests - Use TEST_VERIFY_EXIT () macro instead of if () clause with FAIL_EXIT1 () Changes for v3: - Replace TEST_VERIFY_EXIT () with TEST_VERIFY () to allow executing all tests (do not quit early after error) --- posix/Makefile | 2 +- posix/tst-sched_rr_get_interval.c | 45 +++++++++++++++++++++++++++++++ 2 files changed, 46 insertions(+), 1 deletion(-) create mode 100644 posix/tst-sched_rr_get_interval.c diff --git a/posix/Makefile b/posix/Makefile index f54015b9a8..239fbb340a 100644 --- a/posix/Makefile +++ b/posix/Makefile @@ -108,7 +108,7 @@ tests-internal := bug-regex5 bug-regex20 bug-regex33 \ tst-rfc3484 tst-rfc3484-2 tst-rfc3484-3 \ tst-glob_lstat_compat tst-spawn4-compat tests-container := bug-ga2 -xtests := tst-getaddrinfo4 tst-getaddrinfo5 +xtests := tst-getaddrinfo4 tst-getaddrinfo5 tst-sched_rr_get_interval ifeq (yes,$(build-shared)) test-srcs := globtest tests += wordexp-test tst-exec tst-spawn tst-spawn2 tst-spawn3 diff --git a/posix/tst-sched_rr_get_interval.c b/posix/tst-sched_rr_get_interval.c new file mode 100644 index 0000000000..e5ebe4d004 --- /dev/null +++ b/posix/tst-sched_rr_get_interval.c @@ -0,0 +1,45 @@ +/* Test for sched_rr_get_interval + Copyright (C) 2021 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
