#37931 [NEW]: PHP in Apache crash after Database-Restart while using persistent connections

From: Olaf dot Imig at bifab dot de Operating system: Linux(x86)/Solaris(sparc) PHP version: 5.1.4 PHP Bug Type: OCI8 related Bug description: PHP in Apache crash after Database-Restart while using persistent connections Description: ------------ The following behavior ist reproduceable: -Call the script -shutdown/startup the Database -Call the script => Apache Instance crash The bug is forced, when you call the script many times. For the tests I used the OCI8 stuff from Oracle8i on Solaris and from Oracle8i and Oracle10g on Linux. The result was the same. Without persistent connection all is perfect. Perhaps I can deliver a Solution. I made two changes in the code and the bug vanished. After restart of Database php_oci_connection_ping found invalid connections. The first problem was here, that the function php_oci_connection_close was called twice, first time triggered through zend_hash_del(&EG(persistent_list)... and then through a direct call. The Oracle-C-functions don't like this. Furthermore some pointers was freed twice. The second problem is the call of OCISessionEnd, when the Connection is invalid. Setting of connection->is_close=0 before calling php_oci_connection_close was helpful in this special case. On demand I can send my patch. Reproduce code: --------------- $db=ociplogon("OPASUSER","OPASPASS","TOPASL"); if(!$db){ print "Connection failed\n"; exit; } ocilogoff($db); -- Edit bug report at http://bugs.php.net/?id=37931&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37931&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37931&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37931&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37931&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37931&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37931&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37931&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37931&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37931&r=support Expected behavior: http://bugs.php.net/fix.php?id=37931&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37931&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37931&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37931&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37931&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37931&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37931&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37931&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37931&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37931&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37931&r=mysqlcfg
