Description:
------------
Reproduced on:
 - Debian Lenny (dotdeb): PHP 5.3.2
 - Fastcgi & CLI
 - With and without xcache
 - amd64 architecture


Test script:
---------------
<?php
for($i=0;$i<=100000;$i++){
    $m = mysqli_init();
    mysqli_real_connect($m,'localhost','root','passwordmysql');
    $m = mysqli_close($m);
    unset($m);
    if(($i%1000)===0){
        echo "Memory consumption after $i iterations is " . memory_get_usage() . "<br /><br />";
        flush();
    }
}
die();
?>



Expected result:
----------------
Loop with a little if any memory increase.

Yes that is the result obtained with that ENV var set, howeaver the processes usage still grows.

64031 root      20   0  173m  44m 6652 S   43  2.3   0:09.46 php5

In order to obtain that reading the following was used:
before executing:
USE_ZEND_ALLOC=0
export USE_ZEND_ALLOC=0

Script:
<?php
for($i=0;$i<=1000000;$i++){
    $m = mysqli_init();
    mysqli_real_connect($m,'localhost','root','passwordmysql');
    $m = mysqli_close($m);
    unset($m);
    if(($i%1000)===0){
        echo "Memory consumption after $i iterations is " . memory_get_usage() . "<br /><br />";
        flush();
        usleep(200);
    }
}
die();
?>

and top to obtain the usage

Revision: http://svn.php.net/viewvc/?view=revision&amp;revision=297271
Log: Fixed bug #51347 mysqli_close / connection memory leak
Streams API registers every stream as resource, which lands then
in EG(regular_list), however doesn't clean that when the stream is
closed. At the end this is a para-leak. At the end of the script
all memory is cleaned, however this is a problem for long runnig
scripts that open connections. For every opened and closed connection
about 150 Bytes on 32bit and 250 Bytes on 64bit will be &quot;lost&quot;,
according to memory_get_usage().

Gee, no responses on a proven bug...

Heres valgrind info, sorry no debug symbols for php5-mysql

Can you try with 5.3.3-dev. I am sure I fixed this. Not a real leak, more like streams were freeing memory too late. Please try a snapshot from snaps.php.net

Yes, 5.3.2 has it, the fix I committed is in 5.3.3-dev, the future 5.3.3. I asked that you try it, if possible. Sources are available at http://snaps.php.net
