panic: proto: file "log.proto" is already registered

[cupen]

我有个公共代码库需要同时支持腾讯云 CLS 跟阿里云 SLS ，但很不巧，同时使用这俩 SDK 会遇到 proto runtime panic, 查了下发现两个 SDK 包含 proto.RegisterFile("log.proto", ....) 。

阿里云的代码

aliyun-log-go-sdk/log.pb.go

Lines 441 to 451 in 52078e0

	func init() {
	proto.RegisterType((*LogContent)(nil), "sls.LogContent")
	proto.RegisterType((*Log)(nil), "sls.Log")
	proto.RegisterType((*LogTag)(nil), "sls.LogTag")
	proto.RegisterType((*LogGroup)(nil), "sls.LogGroup")
	proto.RegisterType((*SlsLogPackage)(nil), "sls.SlsLogPackage")
	proto.RegisterType((*SlsLogPackageList)(nil), "sls.SlsLogPackageList")
	proto.RegisterType((*LogGroupList)(nil), "sls.LogGroupList")
	}
	func init() { proto.RegisterFile("log.proto", fileDescriptor_a153da538f858886) }

我尝试去腾讯云 CLS SDK 那边提个 issue. 等反馈。
