Subject: [PATCH 6/6] webrick/httputils: note Kernel#open behavior
Date: Thu, 21 Dec 2017 11:55:07 +0000	[thread overview]
Message-ID: <20171221115507.27500-7-e@80x24.org> (raw)
In-Reply-To: <20171221115507.27500-1-e@80x24.org>

I don't know who uses the load_mime_types method; but it is
conceivable that a user would want to read the results of a
command instead of reading a regular file to load MIME types.

None of the WEBrick-related code in Ruby or default/bundled gems
seems to rely on this method; but it is likely 3rd-party code does.
