Feature #11044: [PATCH] lib/net/protocol.rb (rbuf_fill): avoid exception with read_nonblock

• Status: Closed
• Assignee: normalperson (Eric Wong)
• Target version: -

[normalperson (Eric Wong)]

Exceptions are noisy in debug output and waste allocations.
Use "exception: false" introduced in 2.1 to return symbols for
common errors instead.

Follow-up commits will be prepared to reduce EOFError exceptions
to further quiet debug output and IO.select may be replaced by
io/wait methods if available to reduce allocations.

There's no visible API changes, so I'll commit this in a few days
unless there is an objection and then prepare follow-up patches.

• Status changed from Open to Closed
• % Done changed from 0 to 100

Applied in changeset r50219.
