Bug #51609 [NEW]: pg_copy_to: Invalid results when using fourth parameter

From: Operating system: Linux PHP version: 5.3.2 Package: PostgreSQL related Bug Type: Bug Bug description:pg_copy_to: Invalid results when using fourth parameter Description: ------------ When passing four arguments to pg_copy_to(), the resulting data is corrupted. My guess is that pg_null_as is being freed improperly. A similar pointer is freed conditionally within pg_copy_from(). Could be related to segfault in bug 35168. Test script: --------------- // setup pg_query($db, 'CREATE TEMP TABLE temp_test_table (a INT)'); pg_query($db, 'INSERT INTO temp_test_table VALUES (1)'); // success var_dump(pg_copy_to($db, 'temp_test_table')); // success var_dump(pg_copy_to($db, 'temp_test_table', "\t")); // failure var_dump(pg_copy_to($db, 'temp_test_table', "\t", "\\\\N")); Expected result: ---------------- Three identical arrays: array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "1 " } Actual result: -------------- The third array is corrupted: array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "1 " } array(1) { [0]=> string(2) "@�" } -- Edit bug report at http://bugs.php.net/bug.php?id=51609&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51609&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51609&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51609&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51609&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51609&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51609&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51609&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51609&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51609&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51609&r=support Expected behavior: http://bugs.php.net/fix.php?id=51609&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51609&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51609&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51609&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51609&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51609&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51609&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51609&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51609&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51609&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51609&r=mysqlcfg
