|
// Before you touch the protocol files, you need to be aware of a breaking change
|
|
// that occurred between firmware versions 1.7.3->1.8.0 (Model One) and 2.0.10->
|
|
// 2.1.0 (Model T). The Ethereum address representation was changed from the 20
|
|
// byte binary blob to a 42 byte hex string. The upstream protocol buffer files
|
|
// only support the new format, so blindly pulling in a new spec will break old
|
|
// devices!
|
|
//
|
|
// The Trezor devs had the foresight to add the string version as a new message
|
|
// code instead of replacing the binary one. This means that the proto file can
|
|
// actually define both the old and the new versions as optional. Please ensure
|
|
// that you add back the old addresses everywhere (to avoid name clash. use the
|
|
// addressBin and addressHex names).
|
|
//
|
|
// If in doubt, reach out to @karalabe.
|
|
|
|
// To regenerate the protocol files in this package:
|
|
// - Download the latest protoc https://github.com/protocolbuffers/protobuf/releases
|
|
// - Build with the usual `./configure && make` and ensure it's on your $PATH
|
|
// - Delete all the .proto and .pb.go files, pull in fresh ones from Trezor
|
|
// - Grab the latest Go plugin `go get -u github.com/golang/protobuf/protoc-gen-go`
|
|
// - Vendor in the latest Go plugin `govendor fetch github.com/golang/protobuf/...`
|
