Status: Bogus
Bug Type: Streams related
Operating System: Linux Fedora 4
PHP Version: 5.2.1RC4
New Comment:
I have a daemon written in PHP which connects to remote servers via
fopen() sending POST data.
How do I clean up RAM? I need this daemon to run for months without
restarting it.
PS: I can’t use CURL, cause I need to read from stream with
dynamically changed buffer.

All memory leaks are reported automatically.
stream_context_create() creates stream context and adds it to the
resource list, which is freed on shutdown.
You cannot free the context with unset(), because there might be open
streams using it.

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.
