yes it was for `mapOptional`, which turns out not to be an issue as there's a
specialization for `optional<T>`.
but still having that test to verify deserialization logic wouldn't hurt.
================
Comment at: clang-tools-extra/clangd/ClangdLSPServer.cpp:1746
+
+ if (DiagOpts.EmbedFixesInDiagnostics && !CodeActions.empty())
{
+ Diag.codeActions.emplace(CodeActions);
----------------
we didn't have the empty check before, let's not introduce it now (i.e. we'll
still reply with an empty set of code actions rather than "none" when there are
no fixes known to clangd)
================
Comment at: clang-tools-extra/clangd/ClangdLSPServer.cpp:1751-1753
auto &FixItsForDiagnostic = LocalFixIts[Diag];
- llvm::copy(Fixes, std::back_inserter(FixItsForDiagnostic));
+ llvm::move(std::move(CodeActions),
+ std::back_inserter(FixItsForDiagnostic));
----------------
i am not sure why this logic was appending to the vector rather than just
overwriting. but we shouldn't receive the same diagnostics from the callback
here, am i missing something? so what about just:
```
LocalFixIts[Diag] = std::move(CodeActions);
```
================
Comment at: clang-tools-extra/clangd/Protocol.cpp:735
llvm::json::ObjectMapper O(Params, P);
- return O && O.map("changes", R.changes);
+ return O && O.map("changes", R.changes) && O.map("documentChanges",
R.documentChanges);
}
----------------

yeah you're right, i missed the specialization of `map` for `optional<T>`
