#49936 [Opn]: crash with ftp stream in php_stream_context_get_option()
ID: 49936
Updated by: pierrick@php.net
Reported By: marielyne at acanac dot net
Status: Open
Bug Type: Filesystem function related
Operating System: Windows 7
PHP Version: 5.3SVN-2009-10-20 (snap)
New Comment:
The same problem can be reproduce with the following code
<?php
$dir = 'ftp://your:self@localhost/';
opendir($dir);
opendir($dir);
This bug was introduce in 5.3 with the new way to manage references of
stream context.
Patch can be found here (it modify the php_stream_context_set
signature) :

Or here (same version but with TSRMLS_FETCH to avoid any signature
modification):

New information
Reproduce code:
---------------
<?php
$file = 'ftp://your:self@localhost/test.txt';
echo "start\n";
$fo1 = fopen($file, 'rb');
echo "opened.1\n";
fclose($fo1);
echo "closed.1\n";
$fo2 = fopen($file, 'rb');
echo "opened.2\n";
fclose($fo2);
echo "closed.2\n";
?>
Expected result:
----------------
start
opened.1
closed.1
opened.2
closed.2
Actual result:
--------------
start
opened.1
closed.1
Same result if opening different files
Same result if opening different files from different servers
However, if I move first fclose() below second fopen(), it works as
expected

Does this happen with PHP 5.2.11 ? Does this happen using local
filesystem instead of remote ftp site?
