Detailed Description

A notable exception is URI translation.

Because paths to files are different on indexing machine and client machine ("/remote/machine/projects/llvm-project/llvm/include/HelloWorld.h" versus "/usr/local/username/llvm-project/llvm/include/HelloWorld.h"), they need to be converted appropriately. Remote machine strips the prefix (RemoteIndexRoot) from the absolute path and passes paths relative to the project root over the wire ("include/HelloWorld.h" in this example). The indexed project root is passed to the remote server. Client receives this relative path and constructs a URI that points to the relevant file in the filesystem. The relative path is appended to LocalIndexRoot to construct the full path and build the final URI.

relativePathToURI()

llvm::Expected< std::string > clang::clangd::remote::Marshaller::relativePathToURI

(

llvm::StringRef

RelativePath

)

Translates RelativePath into the absolute path and builds URI for the user machine.

This translation happens on the client side with the RelativePath received from remote index server and IndexRoot is provided by the client.

The relative path passed over the wire has unix slashes.

toProtobuf() [2/7]

LookupRequest clang::clangd::remote::Marshaller::toProtobuf

(

)

toProtobuf() functions serialize native clangd types and strip IndexRoot from the file paths specific to indexing machine.

fromProtobuf() functions deserialize clangd types and translate relative paths into machine-native URIs.
