Herbie Ong 9b3d97c473 encoding/prototext: rewrite of internal/encoding/text ... * Fixes golang/protobuf#842. Unmarshal can now parse singular or repeated message fields without the field separator. * Fixes golang/protobuf#1011. Handles negative 0 properly. * For unknown fields with fixed 32-bit and 64-bit wire types, output is now in hex format with 0x prefix similar to C++ lib output. Previous Go implementation simply outputs these as decimal numbers %d. * All parsing errors, except for unexpected EOF should now contain line and column number info. * Fixed following conformance-related features: * Parse nan,inf,-inf,infinity,-infinity as case-insensitive. * Interpret float32 overflows as inf or -inf. * Parse large int-like number as proto float. * Discard unknown map field if DiscardUnknown=true. * Allow whitespaces/comments in Any type URL and extension field names per spec. * Improves performance and memory usage. It is now as fast and efficient as protojson, if not better on most benchmarks. name old time/op new time/op delta Text/Unmarshal/google_message1_proto2-4 14.1µs ±43% 8.7µs ±12% -38.27% (p=0.000 n=10+10) Text/Unmarshal/google_message1_proto3-4 11.6µs ±18% 7.7µs ± 9% -33.69% (p=0.000 n=10+10) Text/Unmarshal/google_message2-4 6.20ms ±27% 4.10ms ± 5% -33.95% (p=0.000 n=10+10) Text/Marshal/google_message1_proto2-4 12.8µs ± 6% 10.3µs ±23% -19.54% (p=0.000 n=9+10) Text/Marshal/google_message1_proto3-4 11.9µs ±16% 8.6µs ±10% -27.45% (p=0.000 n=10+10) Text/Marshal/google_message2-4 5.59ms ± 5% 5.30ms ±22% ~ (p=0.356 n=9+10) JSON/Unmarshal/google_message1_proto2-4 12.3µs ±61% 13.9µs ±26% ~ (p=0.190 n=10+10) JSON/Unmarshal/google_message1_proto3-4 7.51µs ± 6% 7.86µs ± 1% +4.66% (p=0.010 n=10+9) JSON/Unmarshal/google_message2-4 3.74ms ± 2% 3.94ms ± 2% +5.32% (p=0.000 n=10+10) JSON/Marshal/google_message1_proto2-4 9.90µs ±12% 9.95µs ± 4% ~ (p=0.315 n=9+10) JSON/Marshal/google_message1_proto3-4 7.55µs ± 4% 7.93µs ± 3% +4.98% (p=0.000 n=10+10) JSON/Marshal/google_message2-4 4.29ms ± 5% 4.49ms ± 2% +4.53% (p=0.001 n=10+10) name old alloc/op new alloc/op delta Text/Unmarshal/google_message1_proto2-4 12.5kB ± 0% 2.0kB ± 0% -83.87% (p=0.000 n=10+10) Text/Unmarshal/google_message1_proto3-4 12.2kB ± 0% 1.8kB ± 0% -85.33% (p=0.000 n=10+10) Text/Unmarshal/google_message2-4 5.35MB ± 0% 0.89MB ± 0% -83.28% (p=0.000 n=10+9) Text/Marshal/google_message1_proto2-4 12.0kB ± 0% 1.4kB ± 0% -88.15% (p=0.000 n=10+10) Text/Marshal/google_message1_proto3-4 12.4kB ± 0% 1.9kB ± 0% -84.91% (p=0.000 n=10+10) Text/Marshal/google_message2-4 5.64MB ± 0% 1.02MB ± 0% -81.85% (p=0.000 n=10+9) JSON/Unmarshal/google_message1_proto2-4 2.29kB ± 0% 2.29kB ± 0% ~ (all equal) JSON/Unmarshal/google_message1_proto3-4 2.08kB ± 0% 2.08kB ± 0% ~ (all equal) JSON/Unmarshal/google_message2-4 899kB ± 0% 899kB ± 0% ~ (p=1.000 n=10+10) JSON/Marshal/google_message1_proto2-4 1.46kB ± 0% 1.46kB ± 0% ~ (all equal) JSON/Marshal/google_message1_proto3-4 1.36kB ± 0% 1.36kB ± 0% ~ (all equal) JSON/Marshal/google_message2-4 1.19MB ± 0% 1.19MB ± 0% ~ (p=0.197 n=10+10) name old allocs/op new allocs/op delta Text/Unmarshal/google_message1_proto2-4 133 ± 0% 89 ± 0% -33.08% (p=0.000 n=10+10) Text/Unmarshal/google_message1_proto3-4 108 ± 0% 67 ± 0% -37.96% (p=0.000 n=10+10) Text/Unmarshal/google_message2-4 60.0k ± 0% 38.7k ± 0% -35.52% (p=0.000 n=10+10) Text/Marshal/google_message1_proto2-4 65.0 ± 0% 25.0 ± 0% -61.54% (p=0.000 n=10+10) Text/Marshal/google_message1_proto3-4 59.0 ± 0% 22.0 ± 0% -62.71% (p=0.000 n=10+10) Text/Marshal/google_message2-4 27.4k ± 0% 7.3k ± 0% -73.39% (p=0.000 n=10+10) JSON/Unmarshal/google_message1_proto2-4 95.0 ± 0% 95.0 ± 0% ~ (all equal) JSON/Unmarshal/google_message1_proto3-4 74.0 ± 0% 74.0 ± 0% ~ (all equal) JSON/Unmarshal/google_message2-4 36.3k ± 0% 36.3k ± 0% ~ (all equal) JSON/Marshal/google_message1_proto2-4 27.0 ± 0% 27.0 ± 0% ~ (all equal) JSON/Marshal/google_message1_proto3-4 30.0 ± 0% 30.0 ± 0% ~ (all equal) JSON/Marshal/google_message2-4 11.3k ± 0% 11.3k ± 0% ~ (p=1.000 n=10+10) Change-Id: I377925facde5535f06333b6f25e9c9b358dc062f Reviewed-on: https://go-review.googlesource.com/c/protobuf/+/204602 Reviewed-by: Joe Tsai <thebrokentoaster@gmail.com>		2020-02-05 02:11:08 +00:00
