Bug #59733 trailing spaces trimmed from filenames
Submitted: 2011-04-27 00:21 UTC Modified: 2011-09-21 15:05 UTC
From: dougal at gunters dot org Assigned: bjori (profile)
Status: Closed Package: ssh2 (PECL)
PHP Version: 5.2.6 OS: Ubuntu 10.4
Private report: No CVE-ID: None

Description:
------------
When using dir() on an ssh2.sftp resource, filenames with 
spaces at the end (e.g., 'foo.txt ') get trimmed. Any further 
file operations on such an entry will fail.

Note: I have the 0.11.0-dev version of the ssh2 extension 
installed. It is impractical for me to upgrade or set up a 
test environment for 0.11.2 at this time.

I did try searching for existing bug reports on this, but did 
not find one.


Reproduce code:
---------------
<?php
/*
 * First, create a file with trailing space in filename
 * in the dest dir. E.g.: touch "foo.txt "
 * Then, run this php script.
 */

$link = ssh2_connect('localhost', 22);
ssh2_auth_password($link,'myusername','mypassword');
$sftp = ssh2_sftp($link);

$dir = @dir('ssh2.sftp://' . $sftp . '/home/myusername/test'); 
     
if ( ! $dir ) {
    die("Could not read dir via ssh2.sftp.\n");
}
                       
while (false !== ($entry = $dir->read()) ) {
  echo "'$entry'\t" . filemtime($entry) . "\t" . filesize($entry) . "\n";
}


Expected result:
----------------
The entry for the 'foo.txt ' file should work just as for any 
other file, printing the filename, size, and timestamp.


Actual result:
--------------
Warning: filemtime(): stat failed for foo.txt in 
/home/dougal/test/test.php on line 14

Warning: filesize(): stat failed for foo.txt in 
/home/dougal/test/test.php on line 14
'foo.txt'

Okay, I did upgrade the extension to 0.11.2 (current), and the 
bug still exists. Just FYI.

Oh, and I suppose it's possible that the bug is actually in 
the underlying libssh2 (ver 0.18).

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.
