Subject: [PATCH] selftests: do not macro-expand failed assertion expressions
Date: Mon, 10 Dec 2018 02:00:47 +0300 [thread overview]
Message-ID: <20181209230047.GA1738@altlinux.org> (raw)
I've stumbled over the current macro-expand behaviour of the test
harness:
$ gcc -Wall -xc - <<'__EOF__'
TEST(macro) {
int status = 0;
ASSERT_TRUE(WIFSIGNALED(status));
}
TEST_HARNESS_MAIN
__EOF__
$ ./a.out
[==========] Running 1 tests from 1 test cases.
[ RUN ] global.macro
<stdin>:4:global.macro:Expected 0 (0) != (((signed char) (((status) & 0x7f) + 1) >> 1) > 0) (0)
global.macro: Test terminated by assertion
[ FAIL ] global.macro
[==========] 0 / 1 tests passed.
[ FAILED ]
With this change the output of the same test looks much more
comprehensible:
[==========] Running 1 tests from 1 test cases.

<stdin>:4:global.macro:Expected 0 (0) != WIFSIGNALED(status) (0)
global.macro: Test terminated by assertion
[ FAIL ] global.macro
[==========] 0 / 1 tests passed.
[ FAILED ]
The issue is very similar to the bug fixed in glibc assert(3)
three years ago:
