syscalls/mq_open: fix old tests + convert to use new API
PATCH v5 1/1 syscalls/mq_open: fix old tests + convert to use new API
---
Note about parsing results, there are too many cases (well there are quite a lot of tests). I used your version (added missing TPASS at the end). I have to say, I'd still prefer more complicated if stacement and less duplicity), something like this:
if (TEST_ERRNO != tc->err) {
tst_res(TFAIL | TTERRNO, "%s unexpectedly expected errno: %d", tc->desc,
TEST_ERRNO);
goto CLEANUP;
}if ((tc->ret == 0 && TEST_RETURN < 0) ||
(tc->ret < 0 && TEST_RETURN != tc->ret)) tst_res(TFAIL | TTERRNO, "%s wrong return code: %ld", tc->desc, TEST_RETURN); else tst_res(TPASS | TTERRNO, "%s returned: %ld", tc->desc, TEST_RETURN);
Both versions expect that nobody sets tc-ret > 0, but I suppose it's obvious to anyone that it cannot be > 0.

PATCH v5 1/1 syscalls/mq_open: fix old tests + convert to use new API
Hi!
Pushed with cosmetic changes, removed the now unused enum and fixed a few over 80 character lines, thanks.

if ((
tc->ret== 0 &&TEST_RETURN< 0) ||(tc->ret < 0 && TEST_RETURN != tc->ret)) tst_res(TFAIL | TTERRNO, "%s wrong return code: %ld", tc->desc, TEST_RETURN); else tst_res(TPASS | TTERRNO, "%s returned: %ld", tc->desc, TEST_RETURN);
This one is not that bad, but I still prefer the more verbose one.
As far as code readability goes I think that the best solution is to split the test into two, one for possitive cases and one (or a few more) for negative ones...
