Bug #79469 [NEW]: Property access is not allowed yet on a non-initlized connection

From: morozov at tut dot by Operating system: Linux PHP version: master-Git-2020-04-12 (Git) Package: MySQLi related Bug Type: Bug Bug description:Property access is not allowed yet on a non-initlized connection Description: ------------ When handling connection exceptions, Doctrine DBAL uses the mysqli::$sqlstate property of the connection. Prior to PHP 8, access to the property of a non-initialized connection would result in a warning and returned false: In PHP 8 the warning got promoted to a fatal error. There doesn't seem to be a way to see if the connection is initialized, so it might make sense to just return false there and not raise an error. Additionally, the possible false value of the property is not documented in https://www.php.net/manual/en/class.mysqli.php which leads to false-positive issues during static analysis. Test script: --------------- var_dump(mysqli_init()->sqlstate); Expected result: ---------------- false Actual result: -------------- Fatal error: Uncaught Error: Property access is not allowed yet -- Edit bug report at https://bugs.php.net/bug.php?id=79469&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79469&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79469&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79469&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79469&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79469&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79469&r=support Expected behavior: https://bugs.php.net/fix.php?id=79469&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79469&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79469&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79469&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79469&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79469&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79469&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79469&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79469&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79469&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79469&r=mysqlcfg
