Bug description: stream_context_create() causes memory leaks
Description:
------------
stream_context_create() causes memory leaks.
PHP version is actualy 5.2.1RC5 - latest available.
Reproduce code:
---------------
#!/www/httpd/php/cli -ne
<?php
$postdata=array_fill(0,128,"blah");
for ($a=0;$a<100;$a++){
$options=array('http'=>array(
'method'=>"POST",
'request_fulluri'=>"POST http://www.google.com
HTTP/1.0",
'header' => 'Content-type:
application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context=stream_context_create($options);
unset($context,$options);
echo "current: ",memory_get_usage()," delta:
",(memory_get_usage()-$prev)."\n";
$prev=memory_get_usage();
}
?>
Expected result:
----------------
"current: 74496 delta: 0" line repeated.
Actual result:
--------------
current: 87368 delta: 87368
current: 100008 delta: 12520
<...many lines here>
current: 1319348 delta: 12440
As you can clearly see each iteration eatch 12kb of RAM, which it
shouldn't.
If you comment the
$context=stream_context_create($options);
line out, delta in the example above will always be at 0.
