Bug #52098 [NEW]: Own PDOStatement implementation ignore __call()

From: Operating system: *nix & Win PHP version: 5.3.2 Package: PDO related Bug Type: Bug Bug description:Own PDOStatement implementation ignore __call() Description: ------------ When using an own PDOStatement implementation, __call() is simply ignored in it. *Additionally* it may lead to segfaults if the Statement object is user constructed. The problem is in pdo_stmt.c _zend_function *dbstmt_method_get(){ : if (zend_hash_find(&Z_OBJCE_P(object)->function_table, lc_method_name, method_len+1, (void**)&fbc) == FAILURE) { pdo_stmt_t *stmt = (pdo_stmt_t*)zend_object_store_get_object(object TSRMLS_CC); if (!stmt->dbh->cls_methods[PDO_DBH_DRIVER_METHOD_KIND_STMT]) { [...] stmt is not initialized properly when it comes back from the object store. I didn't search deeper from that point. The bug has already been reported and marked as fixed (46396), but it doesn't seem to have been fixed. Test script: --------------- <?php class MyStatement extends PDOStatement { public function __call($meth, $args) { return "$meth called"; } } $p = new PDO('sqlite::memory:'); $p->setAttribute(PDO::ATTR_STATEMENT_CLASS, array('MyStatement')); $r = $p->query('SELECT 123'); echo $r->foo(); // (1) $obj = new MyStatement; echo $obj->foo(); // (2) Expected result: ---------------- foo called (1) foo called (2) Actual result: -------------- Fatal error: Call to undefined method MyStatement::foo() in XXXX (1) Segmentation Fault (2) -- Edit bug report at http://bugs.php.net/bug.php?id=52098&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52098&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52098&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52098&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52098&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52098&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52098&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52098&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52098&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52098&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52098&r=support Expected behavior: http://bugs.php.net/fix.php?id=52098&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52098&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52098&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52098&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52098&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52098&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52098&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52098&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52098&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52098&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52098&r=mysqlcfg
