Description:
------------
I'm not sure it is a bug on libssh2 or the PECL package. 

I'm using ssh2 0.11 and libssh2 1.1 and recently I upgrade the libssh2 to 1.2. The upgrade goes quite smooth. I've some symlink on my remote machine I use ssh2 function to copy files inside the symlink folder. After upgrade libssh2 to 1.2 I found that the upload doesn't work for those symlink folders. A warning message prompt me that upload failed and only small part of the file is uploaded.

When I downgrade libssh2 back to 1.1 the problem get fixed. Anyone encountered the same problem?

Reproduce code:
---------------
$connection = ssh2_connect($val["ftp_host"], $val["ftp_port"]);
ssh2_auth_password($connection, $val["ftp_username"], $val["ftp_password"]);
ssh2_scp_send($connection, $local_file, $remote_file, 0664);

Expected result:
----------------
No error message at all.

Actual result:
--------------
Only part of the file being uploaded with an error message like this:

Warning:  ssh2_scp_send() [function.ssh2-scp-send]: Failed copying file in /xxx on line 24

I can confirm this bug.

FreeBSD 7.0-RELEASE-p1

+1 on this bug, seen on libssh2 1.2.2, fixed by reverting to 1.1 .

I cannot reproduce this bug, even with old libssh2 1.2.2 packages from ubuntu.

Can you check if this problem still exists?

The file I tried is a binary file. Have you tried something like PDF or JPG? A file in around 1MB will suffice to replicate the issue.

Could you give the latest TRUNK version a try? I've modified the ssh2_scp_send() 
code. It should be fixed, but if it's not, it is much more verbose about error 
situations than it previously was.

A new ssh2 package is released. Please see if problem still occurs.
 [2012-10-17 09:26 UTC] amiroot at yahoo dot com 
Unfortunately the new release hasn't fixed the issue.

Here are the environment I tested it.

OS: Linux RHEL4
libssh: 1.2.4
PHP: 5.2.17
SSH: 0.12
Code: Exactly the same as what I submitted in the initial comment.
Result:
No error at all. The file was uploaded to the remote server but the size is a little bit smaller. I tried a PDF (3MB) and a PPT (4.8M). The file uploaded left only 2.3M and 4.3M.
