* 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>
Next Generation Go Protocol Buffers
WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.
This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
