windows下可用的protocol buffer ，版本3.5.1

2017-12-20 version 3.5.1 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript) Planned Future Changes * Make C++ implementation C++11 only: we plan to require C++11 to build protobuf code starting from 3.6.0 release. Please join this github issue: https://github.com/google/protobuf/issues/2780 to provide your feedback. protoc * Fixed a bug introduced in 3.5.0 and protoc in Windows now accepts non-ascii characters in paths again. C++ * Removed several usages of C++11 features in the code base. * Fixed some compiler warnings. PHP * Fixed memory leak in C-extension implementation. * Added discardUnknokwnFields API. * Removed duplicatd typedef in C-extension headers. * Avoided calling private php methods (timelib_update_ts). * Fixed Any.php to use fully-qualified name for DescriptorPool. Ruby * Added Google_Protobuf_discard_unknown for discarding unknown fields in messages. C# * Unknown fields are now preserved by default. * Floating point values are now bitwise compared, affecting message equality check and Contains() API in map and repeated fields. 2017-11-13 version 3.5.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript) Planned Future Changes * Make C++ implementation C++11 only: we plan to require C++11 to build protobuf code starting from 3.6.0 release. Please join this github issue: https://github.com/google/protobuf/issues/2780 to provide your feedback. General * Unknown fields are now preserved in proto3 for most of the language implementations for proto3 by default. See the per-language section for details. * reserve keyword are now supported in enums C++ * Proto3 messages are now preserving unknown fields by default. If you rely on unknowns fields being dropped. Please use DiscardUnknownFields() explicitly. * Deprecated the unsafe_arena_release_* and unsafe_arena_add_allocated_* methods for string fields. * Added move constructor and move assignment to RepeatedField, RepeatedPtrField and google::protobuf::Any. * Added perfect forwarding in Arena::CreateMessage * In-progress experimental support for implicit weak fields with lite protos. This feature allows the linker to strip out more unused messages and reduce binary size. * Various performance optimizations. Java * Proto3 messages are now preserving unknown fields by default. If you’d like to drop unknown fields, please use the DiscardUnknownFieldsParser API. For example: Parser<Foo> parser = DiscardUnknownFieldsParser.wrap(Foo.parser()); Foo foo = parser.parseFrom(input); * Added a new CodedInputStream decoder for Iterable<ByteBuffer> with direct ByteBuffers. * TextFormat now prints unknown length-delimited fields as messages if possible. * FieldMaskUtil.merge() no longer creates unnecessary empty messages when a message field is unset in both source message and destination message. * Various performance optimizations. Python * Proto3 messages are now preserving unknown fields by default. Use message.DiscardUnknownFields() to drop unknown fields. * Add FieldDescriptor.file in generated code. * Add descriptor pool FindOneofByName in pure python. * Change unknown enum values into unknown field set . * Add more Python dict/list compatibility for Struct/ListValue. * Add utf-8 support for text_format.Merge()/Parse(). * Support numeric unknown enum values for proto3 JSON format. * Add warning for Unexpected end-group tag in cpp extension. PHP * Proto3 messages are now preserving unknown fields. * Provide well known type messages in runtime. * Add prefix ‘PB’ to generated class of reserved names. * Fixed all conformance tests for encode/decode json in php runtime. C extension needs more work. Objective-C * Fixed some issues around copying of messages with unknown fields and then mutating the unknown fields in the copy. C# * Added unknown field support in JsonParser. * Fixed oneof message field merge. * Simplify parsing messages from array slices. Ruby * Unknown fields are now preserved by default. * Fixed several bugs for segment fault. Javascript * Decoder can handle both paced and unpacked data no matter how the proto is defined. * Decoder now accept long varint for 32 bit integers. 2017-08-14 version 3.4.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript) Planned Future Changes * There are some changes that are not included in this release but are planned for the near future - Preserve unknown fields in proto3: We are going to bring unknown fields back into proto3. In this release, some languages start to support preserving unknown fields in proto3, controlled by flags/options. Some languages also introduce explicit APIs to drop unknown fields for migration. Please read the change log sections by languages for details. For general timeline and plan: https://docs.google.com/document/d/1KMRX-G91Aa-Y2FkEaHeeviLRRNblgIahbsk4wA14gRk/view For issues and discussions: https://github.com/google/protobuf/issues/272 - Make C++ implementation C++11 only: we plan to require C++11 to build protobuf code starting from 3.5.0 or 3.6.0 release, after unknown fields semantic changes are finished. Please join this github issue: https://github.com/google/protobuf/issues/2780 to provide your feedback. General * Extension ranges now accept options and are customizable. * "reserve" keyword now supports “max” in field number ranges, e.g. reserve 1000 to max; C++ * Proto3 messages are now able to preserve unknown fields. The default behavior is still to drop unknowns, which will be flipped in a future release. If you rely on unknowns fields being dropped. Please use Message::DiscardUnknownFields() explicitly. * Packable proto3 fields are now packed by default in serialization. * Following C++11 features are introduced when C++11 is available: - move-constructor and move-assignment are introduced to messages - Repeated fields constructor now takes std::initializer_list - rvalue setters are introduced for string fields * Experimental Table-Driven parsing and serialization available to test. To enable it, pass in table_driven_parsing table_driven_serialization protoc generator flags for C++ $ protoc --cpp_out=table_driven_parsing,table_driven_serialization:./ \ test.proto * lite generator parameter supported by the generator. Once set, all generated files, use lite runtime regardless of the optimizer_for setting in the .proto file. * Various optimizations to make C++ code more performant on PowerPC platform * Fixed maps data corruption when the maps are modified by both reflection API and generated API. * Deterministic serialization on maps reflection now uses stable sort. * file() accessors are introduced to various *Descriptor classes to make writing template function easier. * ByteSize() and SpaceUsed() are deprecated.Use ByteSizeLong() and SpaceUsedLong() instead * Consistent hash function is used for maps in DEBUG and NDEBUG build. * "using namespace std" is removed from stubs/common.h * Various performance optimizations and bug fixes Java * Introduced new parser API DiscardUnknownFieldsParser in preparation of proto3 unknown fields preservation change. Users who want to drop unknown fields should migrate to use this new parser API. For example: Parser<Foo> parser = DiscardUnknownFieldsParser.wrap(Foo.parser()); Foo foo = parser.parseFrom(input); * Introduced new TextFormat API printUnicodeFieldValue() that prints field value without escaping unicode characters. * Added Durations.compare(Duration, Duration) and Timestamps.compare(Timestamp, Timestamp). * JsonFormat now acce
