Feature #6088


Add Net::ReadTimeout to distinguish which operation failed

Added by drbrain (Eric Hodel) about 10 years ago. Updated about 10 years ago.

Target version:


This relates to #5765 which improves use of timeout in net/ and #6001 which introduces Net::HTTP::OpenTimeout.

This patch introduces Net::ReadTimeout as a subclass of Timeout::Error and raises it when a read operation takes too long. Users may use this to distinguish between timeouts for reading and timeouts for connecting to a remote host. For a read timeout the user may wish to retry the operation.

I don't object the direction but it should have more document about the new Exception.

Eric, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

  • lib/net/protocol.rb (module Net): Added ReadTimeout to match
    OpenTimeout. ReadTimeout is now raised by rbuf_fill instead of
    Timeout::Error to help users distinguish what type of timeout
    occurred. [ruby-trunk - Feature #6088]
  • lib/net/pop.rb (module Net): Updated documentation for ReadTimeout
    and OpenTimeout.
  • lib/net/http.rb (module Net): ditto
  • lib/net/smtp.rb (module Net): ditto
  • lib/net/telnet.rb (module Net): Net::ReadTimeout is now raised in
    waitfor to match Net::Protocol.
  • test/net/http/test_http.rb: Updated Timeout::Error expectation to
