调研方向
先从复现 repeated enum 问题以及检查 google-protobuf.js 中的堆栈跟踪开始，重点关注 BinaryReader.readPackedField_ 和 readPackedEnum。检查生成的 dist/protobuf/generated/apartment_pb.js 反序列化器，并使用包含 repeated enum 字段的给定二进制数据进行测试。完成标准是：该缓冲区能够在不出现 AssertionError 的情况下反序列化为 Protobuf 对象。
由索引模型根据 Issue 内容生成。
描述
What version of protobuf and what language are you using?
Version: v3.6.1
Language: Javascript with Typescript
What operating system (Linux, Windows, ...) and version?
Windows 10 x64
What runtime / compiler are you using (e.g., python version or gcc version)
im using tsc (Typescript compiler)
In order to generate the .ts files from the .proto im using the command protoc --plugin option with the protoc-gen-ts plugin
What did you do?
Steps to reproduce the behavior:
- create a protobuf file that contains a repeated enum message
- Send a Protobuf binary from my Android App to my Nodejs Express Server
- Attempt to deserialize the buffer in my Express Server
What did you expect to see
a Protobuf Object
What did you see instead?
AssertionError on the repeated enum field.
Make sure you include information that can help us debug (full error message, exception listing, stack trace, logs).
my custom repeated enum field is repeated Amenities amenities = 22; and another one at =23;
my protobuff buffer base64 encoded:
