PHP version: 5.2.8
PHP Bug Type: cURL related
Bug description: stream_get_meta_data don't fills header list
Description:
------------
With php 5.2.8 and curlwrapper option, after calling fopen() on a remote
url, a call to stream_get_meta_data() returns an empty header list.
If a call to fread() is inserted between fopen() and
stream_get_meta_data(), the headers are presents.
The problem appears during a migration from 5.0 without curl, to 5.2 with
curl, so it seems curl related.
Calling the test script via strace shows that the socket is opened, but
there's no call to read() syscall before the stream_get_meta_data is
called.
The problem is not systematically reproduced (certainly due to response
latencies), but appears very often.
Reproduce code:
---------------
this version fails :
$src = fopen("http://www.perdu.com";, 'r');
$meta = stream_get_meta_data($src);
var_dump($meta);
var_dump($http_response_header);
$data= fread($src, 500);
echo $data."\n\n";
this one works (just call fread before get_meta) :
$src = fopen("http://www.perdu.com";, 'r');
$data= fread($src, 500);
$meta = stream_get_meta_data($src);
var_dump($meta);
var_dump($http_response_header);
echo $data."\n\n";
Expected result:
----------------
array(10) {
["wrapper_data"]=>
array(2) {
["headers"]=>
array(8) {
[0]=>
string(15) "HTTP/1.1 200 OK"
[1]=>
string(35) "Date: Thu, 18 Dec 2008 10:15:19 GMT"
[2]=>
string(14) "Server: Apache"
[3]=> ....
Actual result:
--------------
array(10) {
["wrapper_data"]=>
array(2) {
["headers"]=>
array(0) {
}
...
