The problem is simply that the context resource leaks everytime the http
request fails. Seems to have been introduce in r262454.

maybe the array parameters isn´t being removed from memory? i tryed to change
code
inserting a comma after timeout parameter "'timeout'=>1," and it add more
memory
leak per interaction more commas = more memory leak
$context= stream_context_create(array('http'=>array('timeout'=>1,,,,,)));

Description:
------------
hi, when i create a context inside a function i see a memory leak, but when i
create it in the main source code line, i don´t see it...
please check the script..
i think the problem is something that don´t leave memory get back when
destroying context variable
Test script:
---------------
memory leak:
<?php
function g(){
$context=stream_context_create(array('http'=>array('timeout'=>1)));
$ret=file_get_contents('http://172.17.0.5/not_found',0,$context);
unset($context);
return($ret);
}
$base=memory_get_usage();
while(1){
g();
usleep(50000);
echo (memory_get_usage()-$base)."\n";
// memory get bigger and bigger here....
}
?>
memory leak too:
<?php
$base=memory_get_usage();
while(1){
$context=
stream_context_create(array('http'=>array('timeout'=>1)));
$ret=file_get_contents('http://172.17.0.5/not_found',0,$context);
usleep(50000);unset($ret,$context);
echo (memory_get_usage()-$base)."\n";
// memory get bigger and bigger...
}
?>
nice:
<?php
$base=memory_get_usage();
$context= stream_context_create(array('http'=>array('timeout'=>1)));
while(1){
$ret=file_get_contents('http://172.17.0.5/not_found',0,$context);
usleep(50000);unset($ret);
echo (memory_get_usage()-$base)."\n";
// memory is nice here...
}
?>
Expected result:
----------------

Actual result:

well i think that others fields explain...
MEMORY LEAK:
Warning...

(+- 1224 per while interaction)
i don´t know how to solve this, unset don´t work, =null don´t work, and i
don´t find a function to destroy contexts...
