The new comparison rule was added to the spec by
changeset: 5605:33abb649cb63
user: Robert Griesemer <gri@golang.org>
date: Thu Jun 03 16:55:50 2010 -0700
files: doc/go_spec.html
description:
go spec: Base comparison compatibility on assignment compatibility.
Specifically:
- Simplified definition of comparison compatibility and folded into
section on comparison operators since it's only used there.
This is a small language change/cleanup. As a consequence:
- An interface value may now be compared against a non-interface value.
- Channels with opposite directions cannot be compared directly anymore
(per discussion with rsc).

Also add exporter.Drain() to wait for completion.
This makes it possible for an Exporter to fire off a message

even if a client has yet to call to retrieve it.

Two tests start a goroutine which runs exportSend, and then
the tests run importReceive. exportSend creates an export
channel. importReceive asks to receive values on that
channel. Because exportSend runs in a separate goroutine,
it's possible for the export client to receive the request for
values on the channel, from importReceive, before the
goroutine actually creates the export channel. That causes an
error: "export: no such channel: exportedSend". This patch
avoids the race by creating the export channel before starting
the goroutine.
There does not seem to be a similar race condition in the
tests which send data in the other direction.

Based on the observation that a great number of the types that
are copied or compared in interfaces, maps, and channels are
word-sized, this uses specialized copy and equality functions
for them that use a word instead of 4 or 8 bytes. Seems to yield
0-6% improvements in performance in the benchmarks I've run.
For example, with the regexp benchmarks:
Before:
regexp.BenchmarkLiteral 500000 3.26 µs/op
regexp.BenchmarkNotLiteral 100000 13.67 µs/op
regexp.BenchmarkMatchClass 100000 18.72 µs/op
regexp.BenchmarkMatchClass_InRange 100000 20.04 µs/op
regexp.BenchmarkReplaceAll 100000 27.85 µs/op
After:
regexp.BenchmarkLiteral 500000 3.11 µs/op
regexp.BenchmarkNotLiteral 200000 13.29 µs/op
regexp.BenchmarkMatchClass 100000 17.65 µs/op
regexp.BenchmarkMatchClass_InRange 100000 18.49 µs/op

Commands written in Go depend on Go packages, so they
cannot be built by src/cmd/make.bash. They have been
built by src/make.bash after all the packages are done, but
we want to be able to use cgo (written in Go) during the build
of package net. To make this possible, build the commands
from src/pkg/Makefile instead of src/make.bash, so that they
are included in the package dependency analysis.

Implementing Brdstr:
./libbio/brdstr.c:36: p = Brdline(bp, delim);
The symbol names ones will cause a problem loudly if they
fail: they'll error out with symbol name too long. This means
that you can't define an enormous struct without giving the
type a name and then stick it in an interface, because the
type's symbol name will be too long for the object file.
Since this will be a loud failure instead of a silent one,
I'm willing to wait until it comes up in practice.
