Mistaken use of inline rescues in stdlib

Added by Mon_Ouie (Mon ouïe) about 11 years ago. Updated over 10 years ago.

Closed
Target version:
ruby -v:

Description

Hey,

There are two uses of inline rescues in stdlib that look dubious. They are unlikely to ever cause any harm, but still. They've been there for a while now, and are still in trunk. I attached a patch that changes both of them.

In cgi/session.rb:

  def delete
    File::unlink @path+".lock" rescue nil
    File::unlink @path+".new" rescue nil
    File::unlink @path rescue Errno::ENOENT
  end

The rescue part should be on the next line (this has been introduced in a commit that changed indentation).

In scanf.rb:660:

seek(start_position + matched_so_far, IO::SEEK_SET) rescue Errno::ESPIPE

was more likely meant to just silence Errno::ESPIPE exceptions.

I am maintainer of cgi* but not maintainer of lib/scanf.rb

May I commit with lib/scanf.rb ?

Commit your part and assign this to dblack.

Sorry I was misunderstanding that lib/scanf.rb does not have a maintainer.

I've tweeted @david_a_black asking him to check this ticket.

He has been inactive for a long time, though.

Bump.

Should dblack be discharged under the 3 month rule? He has not been active for quite some time.
