Bug #11340
closedWindows で Timeout.timeout を使って Process.waitpid を監視しても timeout が正しく動かない
Description
以下のような、コードでプロセスの実行時間監視をしていたところ、
Windows とその他の環境で異なります。
require 'timeout'
pid = Process.spawn('sleep', '10')
puts Time.now
begin
Timeout.timeout(1) {
Process.waitpid(pid)
}
rescue => e
p e
end
puts Time.now
Linux 等の場合、timeout
で設定した時間で例外があがるのですが、
Windows のときは Process.waitpid
が完了してから Timeout
のスレッドからの例外をうけとっているように見えます。
