Rob Pike	6439010e52	encoding/gob: add "too big" check when writing a message ... Messages that are too big are rejected when read, so they should be rejected when written too. Fixes #10518.

Rob Pike	65dde1ed4b	encoding/gob: use simple append-only buffer for encoding ... Bytes buffers have more API and are a little slower. Since appending is a key part of the path in encode, using a faster implementation speeds things up measurably. The couple of positive swings are likely garbage-collection related since memory allocation looks different in the benchmark now. I am not concerned by them. benchmark old ns/op new ns/op delta BenchmarkEndToEndPipe 6620 6388 -3.50% BenchmarkEndToEndByteBuffer 3548 3600 +1.47% BenchmarkEndToEndSliceByteBuffer 336678 367980 +9.30% BenchmarkEncodeComplex128Slice 78199 71297 -8.83% BenchmarkEncodeFloat64Slice 37731 32258 -14.51% BenchmarkEncodeInt32Slice 26780 22977 -14.20% BenchmarkEncodeStringSlice 35882 26492 -26.17% BenchmarkDecodeComplex128Slice 194819 185126 -4.98% BenchmarkDecodeFloat64Slice 120538 120102 -0.36% BenchmarkDecodeInt32Slice 106442 107275 +0.78% BenchmarkDecodeStringSlice 272902 269866 -1.11% LGTM=ruiu R=golang-codereviews, ruiu CC=golang-codereviews https://golang.org/cl/160990043	2014-10-17 20:51:15 -07:00
