#41877 [NEW]: Trying to insert multiple BLOBs on oracle with pdo_oci hangs up Apache.

From: jarismar at adplabs dot com dot br Operating system: Windows, Linux Ubintu PHP version: 5.2.3 PHP Bug Type: PDO related Bug description: Trying to insert multiple BLOBs on oracle with pdo_oci hangs up Apache. Description: ------------ Unable to read BLOBs from a given table and insert on another one, because php hangs up after inserting the first record on destination table. Reproduce code: --------------- SQL: CREATE TABLE TBL_BLOB (id NUMBER(10), data BLOB); CREATE TABLE TBL_BLOB2 (id NUMBER(10), data BLOB); You will need to insert some records on TBL_BLOB. PHP: try { $oPDO = new PDO($sDSN, $sUserName, $sPassword); $oPDO->beginTransaction(); $sSQLRead = 'SELECT ID, DATA FROM TBL_BLOB'; $oStmtRead = $oPDO->prepare($sSQLRead); $oStmtRead->execute(); $sSQLWrite = 'INSERT INTO TBL_BLOB2 (ID, DATA) VALUES (:id, EMPTY_BLOB()) RETURNING DATA INTO :stream'; $oStmtWrite = $oPDO->prepare($sSQLWrite); while (($aRow = $oStmtRead->fetch())) { $iID = $aRow['ID']; $rData = $aRow['DATA']; if (is_resource($rData)) { $sData = stream_get_contents($rData); fclose($rData); } else { throw new Exception('Error fetching stream'); } $oStmtWrite->bindParam(':id', $iID); $oStmtWrite->bindParam(':stream', $resource, PDO::PARAM_LOB); $oStmtWrite->execute(); if (is_resource($resource)) { fwrite($resource, $sData); fclose($resource); } else { throw new Exception('Error fetching stream'); } } $oStmtRead->closeCursor(); $oPDO->commit(); } catch (Exception $oE) { $oPDO->rollBack(); throw $oE; } $oPDO = null; Expected result: ---------------- No output, but TBL_BLOB2 should have same records from TBL_BLOB. Actual result: -------------- Apache hangs up, the page keeps loading forever. Simply trying to debug the script I see no error, the script finishes normally, but Apache does not send any response. Uncommenting the fclose(<stream>) command then debugging, the debugger stops after writing to TBL_BLOB2 on the second record. -- Edit bug report at http://bugs.php.net/?id=41877&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41877&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41877&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41877&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41877&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41877&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41877&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41877&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41877&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41877&r=support Expected behavior: http://bugs.php.net/fix.php?id=41877&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41877&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41877&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41877&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41877&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41877&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41877&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41877&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41877&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41877&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41877&r=mysqlcfg
