Deletion of file hangs and cannot be cancelled

2018-09-06 21:51

Just caught a bug with WinSCP 5.13.4, which perhaps would be not easy to reproduce.
I have started the file deletion and WinSCP rendered unresponsive, because it didn't react on "Close" of deletion dialog (see attachment) and this dialog captured the mouse input. I had to kill WinSCP with Task Manager. Log:

< 2018-09-06 00:03:08.813 226 Transfer complete
. 2018-09-06 00:03:08.813 Directory listing successful
...
. 2018-09-06 00:03:08.880 Startup conversation with host finished.
. 2018-09-06 00:24:18.303 Deleting file "comments.txt".
> 2018-09-06 00:24:18.312 DELE /ftp/comments.txt
. 2018-09-06 00:24:18.312 Unable to send command. Disconnected.

WinSCP hangs with similar symptoms (not able to close application) also when trying to refresh the directory contents:

. 2018-09-06 23:13:31.339 Directory content loaded from cache.
. 2018-09-06 23:13:36.272 Changing directory to "backup".
. 2018-09-06 23:13:36.274 Synchronizing current directory "/ftp/attic".
> 2018-09-06 23:13:36.277 CWD /ftp/attic
. 2018-09-06 23:13:36.277 Unable to send command. Disconnected.

I suspect that this happened because I have switched off sending keepalive commands (Advanced Site Settings → Connection → Keepalives = Off). I will keep watching...
