-Use better file name generation algorithm for the STOU command.
|

|
|
+Use a better file name generation algorithm for the STOU command. The default
|
||
|
|
+original algorithm simply adds an increasing number suffix to the file name,
|
||
|
|
+which is prone to race conditions if multiple uploaders use the STOU command
|
||
|
|
+with the same file name simultaneously, which can result in failure of the
|
||
|
|
+command. The new algorithm adds a unique random six character suffix to
|
||
|
|
+the file name, which works much better in face of concurrent uploads.
