TorrentListenerWrapper downloadComplete not called if file already exists #228

Closed ghost closed 5 years ago

ghost commented 6 years ago

The following code fails to complete if the file already exists.

                SimpleClient client = new SimpleClient();

                System.out.println("Started download...");
                client.downloadTorrent(torrentFile.getAbsolutePath(), destFolder.getAbsolutePath(), InetAddress.getLocalHost());
                System.out.println("Finished download...");

Tried to debug it and it seems like the downloadComplete isn't called if the file already exists. It is called otherwise.

Following logs for when it works:

all right, downloadComplete listener is invoked when last piece is received and validated. I think we need listener like validationComplete(int validpieces, int totalpieces) and if this method was invoked with validpieces == totalpieces thenclient.downloadTorrent() method must finished. I will try to fix it
