Null characters added when transferring files in text mode

2010-01-30 12:31

I'm using WinSCP 4.25 with "Commander" interface running on Windows 7, the problem existed with 4.19 as well. Please note that I'm not sure whether this is a WinSCP problem or my hoster's one. I'm using SFTP-3, the remote server is running Linux.

Steps to reproduce:

1. Locally, create a text file test.php containing a letter and CR/LF symbols (3 bytes in total, ending with 0D 0A).

2. Upload it to the remote server. With the .php extension, it uploads in text mode by default, and I expect CR/LF to be converted to simply LF. It is, but the file size is still 3 bytes (2 expected): there is a null character appended to the end of the file.

3. Download the file back, it's 4 bytes in size now (LF converted to CR/LF + the null character).

4. Upload the file again. It's 4 bytes on the server (CR/LF converted to LF, another null character added).

5. Download the file. It's 5 bytes already (LF converted to CR/LF, two null characters at the end).

Please post a full log file showing the problem.

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. For posting extensive logs you may use pastebin or similar application. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

Here you are. The host/user names and the IP address are replaced with x-es if you don't mind.

Has this been confirmed as a bug and/or resolved?

I'm running Version 5.02 (Build 1456) on Windows Vista and getting null characters in the middle of files.

Please post a full log file showing the problem.

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. For posting extensive logs you may use pastebin or similar application. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

adding characters at the beginning of the file

2012-03-07 01:06

I am transferring file from from windows & Pro to unix server from SSIS using Execute Process task
C:\Program Files (x86)\WinSCP\WinSCP.com version number is 5.0.6(Build 2074)

I am using the following script to connect:

option batch abort
option confirm off
open sftp:// username:password@IPAdress
cd \myfolder\
lcd c:\temp\myfile.txt
close
exit

There are some characters added at the beginning of the file.
Here is the log file

First, the log is for a different script that you have posted.

Second, what characters at beginning of what file?

Please disregard my request, it had nothing to do with WinSCP.

I have this too.

It's really annoying as it is random if it will add a null character in the middle of the file or not.

However, only ever happens to me when using the internal WinScp editor to change a file.
Unfortunately, this makes winscp a problem as it'll upload the file apparently "fine" but will cause all sorts of problems to a server relying on the xml thats changed.

If you then reload the file and highlight the text in the editor you can see the new character that has been created.

I've cases where files have been loaded, edited, saved fine and then re-edited in the same winscp session, saved fine, re-edited and bang - random null.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.
