Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR fixes several causes of test flakiness and re-enables the tests that were disabled in #10665, #10669 and #10673. Specifically, it fixes: - A race condition in the file worker that caused it to report an incomplete snapshot prefix in the inlay hint request (confirmed to be the cause of #10665) - A bug in the test runner where it didn't correctly account for non-deterministic message ordering inducing different RPC pointer numbering (confirmed to be the cause of #10673) - A race condition in the watchdog that would sometimes cause the module hierarchy to be empty (likely the cause of #10669, but not confirmed as this issue only reproduced again once in tens of thousands of test runs on various machines, including CI) - An unrelated bug in the module hierarchy implementation that would cause it to report an empty module hierarchy when the file was changed It also replaces some calls to `Task.get` in the language server with `IO.wait` to protect the code against unfortunate compiler re-ordering. |
