There was a problem hiding this comment.
We can use SystemCallError that is an ancestor class of them:
Suggested change
| rescue IOError, Errno::EPIPE, Errno::ESPIPE, Errno::EINVAL | |
| rescue IOError, SystemCallError |
## Why? If via IO.pipe, `IOError` exception is not raised, but `Errno::ESPIPE` or `Errno::EPIPE` or `Errno::EINVAL` exception is raised. - CRuby ``` @er_source.pos #=> Errno::ESPIPE Exception: Illegal seek ``` - CRuby (Windows (Ruby 2.6 or earlier)) ``` @er_source.pos #=> Errno::EINVAL: Invalid argument ``` - JRuby ``` @er_source.pos #=> Errno::EPIPE: Broken pipe - No message available ``` Co-authored-by: Sutou Kouhei <kou@clear-code.com>
