Feature #6088

Add Net::ReadTimeout to distinguish which operation failed

Added by drbrain (Eric Hodel) almost 9 years ago. Updated almost 9 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.
