Bug #81113 [NEW]: PDO holds some non-GCable reference

From: m at m dot cz Operating system: any PHP version: 8.0.7 Package: PDO related Bug Type: Bug Bug description:PDO holds some non-GCable reference Description: ------------ See https://github.com/atk4/data/pull/878/commits/83345e3ce4b9006efe9bfe50befacef20f3aee08 When DBAL connection is closed manually - all references to PDO connection are removed manually (by https://github.com/doctrine/dbal/blob/3.1.0/src/Connection.php#L646 ) - then PDO connection is released correctly. But when there is no reference to an object holding the PDO connection (in this case Doctrine\DBAL\Connection), PDO connection is NOT released when GC is run. I belive PDO holds some reference which is not decreased during GC cycle. -- Edit bug report at https://bugs.php.net/bug.php?id=81113&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81113&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81113&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81113&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81113&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81113&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81113&r=support Expected behavior: https://bugs.php.net/fix.php?id=81113&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81113&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81113&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81113&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81113&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81113&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81113&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81113&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81113&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81113&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81113&r=mysqlcfg
