PHP Bug Type: cURL related
Bug description: curl CURLOPT_INFILE leaks handle reference
Description:
------------
File handles are normally closed automatically when the reference count
hits zero. For example, if you fopen() something in a function and only
assign it to a local variable, the file is closed when the function
returns.
CURLOPT_INFILE breaks this behavior. Presumably, the curl resource
destructor does not decrement the reference count for the file handle.
Reproduce code:
---------------
<?
$name = tempnam("/tmp", "phpbug");
$n = count(scandir("/proc/self/fd"));
test_simple($name);
var_dump(count(scandir("/proc/self/fd")) == $n);
test_curl($name, true);
var_dump(count(scandir("/proc/self/fd")) == $n);
test_curl($name, false);
var_dump(count(scandir("/proc/self/fd")) == $n);
function test_simple($name)
{
$fp = fopen($name, "r");
}
function test_curl($name, $close)
{
$fp = fopen($name, "r");
$c = curl_init();
curl_setopt($c, CURLOPT_PUT, true);
curl_setopt($c, CURLOPT_INFILE, $fp);
curl_setopt($c, CURLOPT_INFILESIZE, 0);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_exec($c);
curl_close($c);
if ($close)
fclose($fp);
}
?>
Expected result:
----------------
bool(true)
bool(true)
bool(true)
Actual result:
--------------
bool(true)
bool(true)
bool(false)
