Description: ------------ It seems that stream function can cause memory leaks so easily. We hope the stream developer fix it as soon as possible. Here is another one: it leaks when you add ./configure --enable-debug Reproduce code: --------------- <?php class upper_filter extends php_user_filter{ function filter($in, $out, &$consumed, $closing) { while($bucket=stream_bucket_make_writeable($in)){ $fp=fopen("2.txt", "w"); $bucket=stream_bucket_new($fp, "Abc\n"); $bucket->data = strtoupper($bucket->data); $consumed += $bucket->datalen; stream_bucket_append($out, $bucket); } return PSFS_PASS_ON; } } stream_filter_register("upper", "upper_filter"); $fp=fopen("2.txt", "w"); stream_filter_append($fp, "upper"); fread($fp, 1024); fwrite($fp, "Thank you\n"); fclose($fp); readfile("2.txt"); unlink("2.txt"); ?> Actual result: -------------- [EMAIL PROTECTED] sqchen]$ $php tt.php ABC ~ [Tue Mar 28 16:54:43 2006] Script: 'tt.php' /home/sqchen/sqchen/php-5.1.2/main/streams/filter.c(129) : Freeing 0x083EE864 (10 bytes), script=tt.php [Tue Mar 28 16:54:43 2006] Script: 'tt.php' /home/sqchen/sqchen/php-5.1.2/main/streams/filter.c(126) : Freeing 0x083EE814 (32 bytes), script=tt.php === Total 2 memory leaks detected === -- Edit bug report at http://bugs.php.net/?id=36886&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36886&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36886&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36886&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36886&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36886&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36886&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36886&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36886&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36886&r=support Expected behavior: http://bugs.php.net/fix.php?id=36886&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36886&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36886&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36886&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36886&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36886&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36886&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36886&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36886&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36886&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36886&r=mysqlcfg
