# Upgrading the Protobuf Library

1. Get a new protobuf release from https://github.com/google/protobuf/releases

2. Run `$ ./toolkit/components/protobuf/upgrade_protobuf.sh ~/path/to/release/checkout/of/protobuf`.

3. Update the moz.build to export the new set of headers and add any new .cc

   files to the unified sources and remove old ones. Note that we only

   need:

   - files contained in the `libprotobuf_lite_la_SOURCES` target

   (https://github.com/protocolbuffers/protobuf/blob/main/src/Makefile.am)

   - the header files they need

   - gzip streams (for devtools)

4. Re-generate all .pb.cc and .pb.h files using `$ ./toolkit/components/protobuf/regenerate_cpp_files.sh`.
