Bug #71667 [NEW]: "computed" column name behavior is inconsistent with mssql extension

From: adam dot baratz at gmail dot com Operating system: Linux PHP version: 5.6.19RC1 Package: PDO DBlib Bug Type: Bug Bug description:"computed" column name behavior is inconsistent with mssql extension Description: ------------ The output is inconsistent with the output from executing the same query using the mssql extension (see expected result section for details). Test script: --------------- <?php if (!extension_loaded('pdo_dblib')) { die('skip not loaded'); } require dirname(__FILE__) . '/config.inc'; $stmt = $db->prepare('SELECT 1, 2 AS named, 3'); $stmt->execute(); var_dump($stmt->fetch()); Expected result: ---------------- The mssql extension starts "computed" names at "computed" and uses a sequence to name subsequent columns, not the column number: https://github.com/php/php-src/blob/PHP-5.6.19/ext/mssql/php_mssql.c#L1225 In this case, the first column should be "computed" and the third should be "computed1." Additionally, debug mode should not be reporting memory leaks. Actual result: -------------- --------------------------------------- /vagrant/pdo_dblib-clean/dblib_stmt.c(106) : Block 0x00000000 status: NULL --------------------------------------- array(6) { ["computed0"]=> string(1) "1" [0]=> string(1) "1" ["named"]=> string(1) "2" [1]=> string(1) "2" ["computed2"]=> string(1) "3" [2]=> string(1) "3" } [Thu Feb 25 23:04:41 2016] Script: '/vagrant/pdo_dblib-clean/tests/timeout.php' /home/vagrant/php-src/main/spprintf.c(245) : Freeing 0x7F1E9FB6B518 (79 bytes), script=/vagrant/pdo_dblib-clean/tests/timeout.php Last leak repeated 1 time [Thu Feb 25 23:04:41 2016] Script: '/vagrant/pdo_dblib-clean/tests/timeout.php' /vagrant/pdo_dblib-clean/dblib_stmt.c(211) : Freeing 0x7F1E9FB6D270 (6 bytes), script=/vagrant/pdo_dblib-clean/tests/timeout.php === Total 3 memory leaks detected === -- Edit bug report at https://bugs.php.net/bug.php?id=71667&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71667&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71667&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71667&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71667&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71667&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71667&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71667&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71667&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71667&r=support Expected behavior: https://bugs.php.net/fix.php?id=71667&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71667&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71667&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71667&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71667&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71667&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71667&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71667&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71667&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71667&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71667&r=mysqlcfg
