Bug #75175 [NEW]: Opcache_reset() does not clear cache

From: tm8544 at hotmail dot com Operating system: Windows 10 x64 PHP version: 7.2.0RC1 Package: opcache Bug Type: Bug Bug description:Opcache_reset() does not clear cache Description: ------------ After opcache_reset, with version 7.2.0RC1 "used_memory" still occupies much more memory than with version 7.1.9. Opcache runtime configuration stays the same. Expected result shows test script output with PHP 7.1.9, and actual result shows test script output with PHP 7.2.0RC1. Test script: --------------- <html><body><pre><?php echo "Memory Usage before reset:\r\n"; $a = opcache_get_status(); var_dump($a["memory_usage"]); echo "----------------------\r\n"; echo "Reset Opcache\r\n"; $ok = opcache_reset(); var_dump($ok); echo "----------------------\r\n"; echo "Memory Usage after reset:\r\n"; $a = opcache_get_status(); var_dump($a["memory_usage"]); ?></pre></body></html> Expected result: ---------------- Memory Usage before reset: array(4) { ["used_memory"]=> int(701384) ["free_memory"]=> int(133516344) ["wasted_memory"]=> int(0) ["current_wasted_percentage"]=> float(0) } ---------------------- Reset Opcache bool(true) ---------------------- Memory Usage after reset: array(4) { ["used_memory"]=> int(701384) ["free_memory"]=> int(133516344) ["wasted_memory"]=> int(0) ["current_wasted_percentage"]=> float(0) } Actual result: -------------- Memory Usage before reset: array(4) { ["used_memory"]=> int(18272056) ["free_memory"]=> int(115945672) ["wasted_memory"]=> int(0) ["current_wasted_percentage"]=> float(0) } ---------------------- Reset Opcache bool(true) ---------------------- Memory Usage after reset: array(4) { ["used_memory"]=> int(18272056) ["free_memory"]=> int(115945672) ["wasted_memory"]=> int(0) ["current_wasted_percentage"]=> float(0) } -- Edit bug report at https://bugs.php.net/bug.php?id=75175&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75175&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75175&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75175&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75175&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75175&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75175&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75175&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75175&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75175&r=support Expected behavior: https://bugs.php.net/fix.php?id=75175&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75175&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75175&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75175&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75175&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75175&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75175&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75175&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75175&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75175&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75175&r=mysqlcfg
