[jira] Created: (VFS-176) Attempt to copy a file via FTP will cause
temporary lockup and create 0 byte file
Attempt to copy a file via FTP will cause temporary lockup and create 0 byte file
---------------------------------------------------------------------------------
Key: VFS-176
URL: https://issues.apache.org/jira/browse/VFS-176
Project: Commons VFS
Issue Type: Bug
Affects Versions: 1.0
Environment: FtpFileSystem
Reporter: Andrew Franklin
Priority: Minor
The following exception occurred when I tried transferring a file via ftp that the user did not have read access to. (ie, it has been chmod 400 to another user).
Commons-vfs will create a 0 byte file in the destination folder, but that file never grows. Also, no messages are logged at
this time. So it appears to the user that the transfer has frozen, until the exception is thrown.
I suspect the problem is in commons-net.
Note: this exception is not thrown immediately. It takes a few minutes before this fires.
