Bug #70289 [NEW]: Different sort in php7 (and hhvm) compared to php5

From: kjarli at gmail dot com Operating system: Ubuntu 14.04 PHP version: 7.0.0beta3 Package: Testing related Bug Type: Bug Bug description:Different sort in php7 (and hhvm) compared to php5 Description: ------------ I haven't gotten a proper test setup, but I do have the travis builds. I was working on a priority sorting feature and I had added a test to verify sort orders. On php5 it consistently went right, but on php7 and hhvm it was in reversed order. I fixed it by adding a secondary sort (strcmp). Build #45 (failed): https://travis-ci.org/iltar/http-bundle/builds/76059069 Build #46 (failed): https://travis-ci.org/iltar/http-bundle/builds/76061283 Build #47 (fixed): https://travis-ci.org/iltar/http-bundle/builds/76062321 The test in question: https://github.com/iltar/http-bundle/blob/feature/property-accessor/test/DependencyInjection/DecorateRouterPassTest.php#L72-L112 It's about the one with a priority of 50, which is reversed as you can see in the failed output. Test script: --------------- https://github.com/iltar/http-bundle/blob/feature/property-accessor/test/DependencyInjection/DecorateRouterPassTest.php#L72-L112 Expected result: ---------------- I expect to see consistent sorting, but that was not the case. sequence: app.henk2_50 app.henk_50 Actual result: -------------- sequence: app.henk_50 app.henk2_50 -- Edit bug report at https://bugs.php.net/bug.php?id=70289&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70289&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70289&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70289&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70289&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70289&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70289&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70289&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70289&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70289&r=support Expected behavior: https://bugs.php.net/fix.php?id=70289&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70289&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70289&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70289&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70289&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70289&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70289&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70289&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70289&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70289&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70289&r=mysqlcfg
