Häufige Annahme

Setting TEMPORARILY_DISABLE_PROTOBUF_VERSION_CHECK=1 in the environment disables protobuf gencode version validation during proto loading

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• Setting TEMPORARILY_DISABLE_PROTOBUF_VERSION_CHECK to '1' fails to bypass gencode version validation because the check strictly requires 'true', continuing to raise VersionError on newer gencode
• Setting TEMPORARILY_DISABLE_PROTOBUF_VERSION_CHECK to case-insensitive 'true' disables gencode validation and allows newer gencode to load without VersionError
• Importing gencode generated by a newer protoc version raises VersionError identifying the version mismatch
• Importing gencode generated by an older protoc version succeeds without error on a newer runtime
• Dynamic mutations to TEMPORARILY_DISABLE_PROTOBUF_VERSION_CHECK take effect immediately on subsequent validation calls rather than caching on module import
