Hi list,
Howto capture stdout + stderr from jobs invoked with rake?
I run rake from cron. I have a
def log(msg)
str = Time.now.to_s + ": " + msg + "\n"
file = $settings['logfile']
File.open(file, 'a+') {|f| f.write str }
end
it only tells where it went wrong, but not what went wrong.
any ideas how to do better logging with the following code?

reciever = $settings['backup_recievers']
mime = 'application/octet-stream'
chunks = Dir.glob(prefix + '*').sort
log("revision #{rev}, consists of #{chunks.size} chunks.")
chunks.each_with_index do |filename, index|
log("sending chunk##{index+1}.")
bodytext = "this is chunk##{index+1} out of #{chunks.size} in total."
attachments = [[filename, mime]]
begin
send_mail(reciever, subject, bodytext, attachments)
rescue => e
log("ERROR: failed sending, #{e.inspect}")
ok = false
end

msg = ok ? "OK" : "with error!"
log("backup completed #{msg}\n\n")
end
