Bug #70579 [NEW]: Test ext/gmp/tests/gmp_random_seed.phpt broken

From: rainer dot jung at kippdata dot de Operating system: PHP version: 7.0.0RC3 Package: GNU MP related Bug Type: Bug Bug description:Test ext/gmp/tests/gmp_random_seed.phpt broken Description: ------------ The test ext/gmp/tests/gmp_random_seed.phpt assumes the same responses on every platform. That is not true. The calls to gmp_random() in that test will return different values depending on "number of bits per limb". For a 64 Bit Linux system, the results will always be the same, but e.g. for a 32 Bit Solaris Sparc the results are different (and must be). Probably also for a 32 Bit Linux system (haven't checked that part). Possible solutions: - Remove gmp_random() from the test - Only check for numbers as return, or check for changes of the number between different calls to gmp_random() - Resolve https://bugs.php.net/bug.php?id=62375 and add different tests for different limb sizes (I don't know how to do a platform specific switch in the test framework) - Try to detect limb size from the return value of gmp_random(1) and correct arguments of other gmp_random() with a corresponding correction factor. That will not work for gmp_random() without arguments, so drop these calls. - Use Regexp expectation values to allow all different possible values (at least for limb size 32 and 64). -- Edit bug report at https://bugs.php.net/bug.php?id=70579&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70579&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70579&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70579&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70579&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70579&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70579&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70579&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70579&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70579&r=support Expected behavior: https://bugs.php.net/fix.php?id=70579&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70579&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70579&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70579&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70579&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70579&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70579&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70579&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70579&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70579&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70579&r=mysqlcfg
