[PATCH] D131569: [clangd] Allow updates to be canceled after compile flags retrieval

[Ilya Biryukov via Phabricator via cfe-commits]

ilya-biryukov added a comment.

Could you please add a test with a compilation database that models the blocking behavior, attempts cancellation and ensures no diagnostics are produced?
I also suggest adding a callback similar to `Callbacks.onFailedAST`, which could be used for testing this behavior.
The test should also check that subsequent updates and reads get resolved properly.

We don't have an actual implementation for the client code that relies on this in-tree, but the unit test will help to ensure we don't break this contract.
