Bug #59789 using ssh2.sftp stream on 64bit vs. 32bit
Submitted: 2011-05-27 08:17 UTC Modified: 2011-09-21 13:08 UTC
From: lampacz@php.net Assigned: bjori (profile)
Status: Closed Package: ssh2 (PECL)
PHP Version: 5.3.5 OS: Linux
Private report: No CVE-ID: None
 [2011-05-27 08:17 UTC] lampacz@php.net
Description:
------------
On 32bit system works scandir/opendir+readdir with ssh2.sftp ok but on 64bit system is problem - empty array. Tried on 5.3.2 and same results. I don't know if it's problem of ssh2 or global in scandir/opendir+readdir

Reproduce code:
---------------
if (!($oCon = ssh2_connect($host, $port)))
die('#1');

if (!ssh2_auth_password($oCon, $user, $pass))
die('#2');

$oSFTP = ssh2_sftp($oCon);

$sDir = "ssh2.sftp://$oSFTP/";

$aX = scandir($sDir);
print_r($aX);

Expected result:
----------------
At least if directory empty:
Array
(
    [0] => .
    [1] => ..
)

Actual result:
--------------
Array
(
)

This seems to be a bug in ssh2_sftp.c, which passes an int-pointer to php_basename, however the latter treats it as a size_t-pointer.

This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
