Bug #70580 [Opn->Csd]: Test Zend/tests/bug42143.phpt is broken

Edit report at https://bugs.php.net/bug.php?id=70580&edit=1 ID: 70580 Updated by: carusogabriel@php.net Reported by: rainer dot jung at kippdata dot de Summary: Test Zend/tests/bug42143.phpt is broken -Status: Open +Status: Closed Type: Bug Package: Testing related Operating System: Solaris PHP Version: 7.0.0RC3 -Assigned To: +Assigned To: carusogabriel Block user comment: N Private report: N New Comment: Closing as this tests isn't failing anymore: http://gcov.php.net/viewer.php?version=PHP_HEAD&func=tests Previous Comments: ------------------------------------------------------------------------ [2015-10-24 04:48:25] kalle@php.net Now its been a while with proper testing writing, but I think its possible that we change the EXPECT section to EXPECTF and then have something like: %NaN|INF% or similar, I should probably consult run-tests.php for this, but it seems most reasonable we keep the test for most code path coverage. ------------------------------------------------------------------------ [2015-09-25 12:05:16] rainer dot jung at kippdata dot de This applies also to PHP 5.4-5.6 (latest releases). ------------------------------------------------------------------------ [2015-09-25 11:59:46] rainer dot jung at kippdata dot de Description: ------------ The test Zend/tests/bug42143.phpt contains: 13 var_dump(log10(-1) == log(-1)); 14 var_dump(log10(-1) != log10(-1)); On Linux, that test works, because the logarithm of -1 returns NAN as expected. On Solaris the log returns -INF and that part of the test fails. This behavior is allowed by the specifications: See in http://pubs.opengroup.org/onlinepubs/9699919799/functions/log.html "For finite values of x that are less than 0 ..., a domain error shall occur, and either a NaN (if supported), or an implementation-defined value shall be returned." Since there are a lot of other but similar tests in Zend/tests/bug42143.phpt, I suggest to drop these two lines. See attached patch. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70580&edit=1
