#25093 [NEW]: no way to free failed query => memory leak

From: pvx at pv2c dot sk Operating system: Linux PHP version: 4.3.2 PHP Bug Type: PostgreSQL related Bug description: no way to free failed query => memory leak Description: ------------ pg_query doesn't return resource for failed queries - that's not very wise, IMHO (see related bug 18747), but the real problem with this is, that you cannot free failed results. It may not be noticeable if you have only a few failed queries, but it becomes a serious problem if you have lots. Try the example code. Reproduce code: --------------- // assume one table "aaa" with one column "test", that is // unique (primary key maybe) $con=pg_connect(...); for($t=0; $t<10000; $t++) { $ret = pg_query($con, "INSERT INTO aaa (test) VALUES 1"); // $ret is FALSE (cannot inset duplicate value) => no way to free it } Expected result: ---------------- Some way to free the result resource... Actual result: -------------- PHP memory consumption grows *really fast*, in my case it even ignores memory_limit setting in php.ini. -- Edit bug report at http://bugs.php.net/?id=25093&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25093&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25093&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25093&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25093&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25093&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25093&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25093&r=support Expected behavior: http://bugs.php.net/fix.php?id=25093&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25093&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25093&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25093&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25093&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25093&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25093&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25093&r=gnused
