Bug description: memory leaks in stream problems
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:
--------------
