> We would like to move the preamble index out of the critical path
Could you provide motivation why you need to do it? What is the underlying
problem that this change is trying to solve?
We rely on preamble being indexed at that particular time for correct results
in future steps, it's definitely not a no-op change even if the threading
issues are resolved (see the other comment).
================
Comment at: clang-tools-extra/clangd/ClangdServer.cpp:88
+ if (PreambleIndexTask)
+ PreambleIndexTask->runAsync("task:" + Path + Version,
+ std::move(Task));
----------------
This definitely does not work. After `onPreambleAST` returns, the AST will be
destroyed and async tasks may access it afterwards.
