Overwriting without confirmation

2018-12-05 20:21

Using WinSCP 5.13.5 (Build 8967) with default preferences except "Maximal number of transfers at the same time" set to "1".

I selected many files on my ftp server.
I started to "download and delete (F6)" these files to my local disk in the Background (queue1).
This background process was still in progress when I refreshed the ftp directory and selected new files to "download and delete (F6)" (queue2).
Accidently I selected some files from queue1 again so that these files were also in queue2.

When queue2 is processing such an already moved file it displays an error message that it can't open the source file.
Bug: At this time the target file is already overwritten with a zero bytes file.

Can you reproduce the problem?
I believe this should happen only if you instruct WinSCP to download very same file at the very same moment, not when "processing such an already moved file".

Yes. After I discovered this bug I did upgrade to the latest version and could reproduce this problem.

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. 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 can mark the attachment as private.
