Status: Open
Bug Type: HTTP related
Operating System: Debian Linux (etch)
PHP Version: 5.2.10
New Comment:
The reproduce code is not completly correct: The curl_close() call was
meant to be after curl_exec() and before the first fclose().
But interestingly this does not change the behaviour in neither 5.2.9
nor 5.2.10.

Description:
------------
When passing an open, writable file handle to Curl as the CURLOPT_FILE
option, the refcount to that file handle is increased without being
decreased when calling curl_close.
Thus the file handle has to be closed TWICE to actually being flushed
and closed. In the reproduce code the file handle is still a valid
resource after the first call to fclose().
The bug is reproducable in PHP 5.2.10. In 5.2.9 the code works as
expected.
In 5.2.10 in ext/curl/interface.c:1440 the call
zend_list_addref(Z_LVAL_PP(zvalue));
was added. Maybe the problem origins here, if there is no corresponding
delref in curl_close()?
Reproduce code:
---------------
$fh = fopen('curl.out', 'w');
$c = curl_init('http://example.com');
curl_setopt($c, CURLOPT_FILE, $fh);
curl_exec($c);
fclose($fh);
echo "content 1: ". file_get_contents('curl.out') ."\n";
if (is_resource($fh)) {
echo "file still open -> wrong\n";
} else {
echo "file closed -> correct\n";
exit;
}
fclose($fh);
if (is_resource($fh)) {
echo "file open 2\n";
}
curl_close($c);
echo "content 2: ". file_get_contents('curl.out') ."\n";
Expected result:
----------------
content 1: <HTML>
<HEAD>
<TITLE>Example Web Page</TITLE>
</HEAD>
[..]
file closed -> correct
Actual result:
--------------
content 1:
file still open -> wrong
content 2: <HTML>
<HEAD>
<TITLE>Example Web Page</TITLE>
</HEAD>
[..]
