近永と申します。

Net::FTP#resume= を使用してファイルのアップロードの  
再開を可能にしようとしてみたところ、転送結果のファイルが  
è¿½åŠ ã§è»¢é€ã—ãŸéƒ¨åˆ†ã ã‘ã«ãªã£ã¦ã—ã¾ã†ç¾è±¡ã«é­é‡ã—ã¾ã—ãŸã€‚  
使用していた ftp サーバは vsftp (@RedHat Enterprise Linux)  
というものです。

サンプルスクリプトはこんなかんじです。

=== ftp\_upload.rb ===  
require “net/ftp”

ftp = Net::FTP.new(, , )  
ftp.resume = true

# ftp.putbinaryfile(“samplefile”)

転送途中で停止させてから再実行すると、リモートには元のファイルの  
後半(続行した部分)だけのファイルができあがります。

アップロードの resume は REST+STOR で実現されていますが、  
APPE を使用すれば期待したように再開できました。  
パッチを添付します。  
ご検討よろしくお願いします。
