PHP Bug Type: cURL related
Bug description: POST requests have an emalloc leak
Description:
------------
Adding a bug for this so we can track it.
The leak size isn't constant even though the post data size in this
example is constant, and the returned data (a dns error, presumably) is the
same. Seems like there is something weird in our postfield handling code
in the curl extension. Note also that it stabilizes somehow, although this
is an extremely simplified version of a long-running command-line script
that seems to grow on each post with wildly varying post data.
Reproduce code:
---------------
<?php
function curl($post) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "www.fdhfkdsslak.bogus");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
if($post) {
curl_setopt($ch, CURLOPT_POST, 1);
for($args='',$i=0;$i<75;$i++) $args .= "a=$i&";
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
unset($args);
}
curl_exec($ch);
curl_close($ch);
}
echo "start ".memory_get_usage()."\n";
for($i=0;$i<10;$i++) {
curl(0);
echo "GET ".memory_get_usage()."\n";
}
for($i=0;$i<10;$i++) {
curl(1);
echo "POST ".memory_get_usage()."\n";
}
?>
Expected result:
----------------
No memory_usage increase from one POST request to the next.
Actual result:
--------------
start 326616
GET 327256
GET 327276
