## Summary ### Preamble completeness check - `is_preamble_complete()` in `scan.cpp`: checks whether `#include`/`import`/`export module` directives in the preamble region are syntactically complete (have closing `>`/`"`/`;`) - `ensure_pch` defers PCH rebuild when preamble is incomplete (user still typing), reuses old PCH instead of failing ### #include / import completion - Master intercepts completion requests in `#include "..."` / `#include <...>` / `import ...` contexts before forwarding to worker - `complete_include()`: searches include paths (from compile args via `SearchConfig`) using `DirListingCache`, supports quoted/angled/multi-level paths - `complete_import()`: filters `path_to_module` map by prefix - Word boundary checks prevent false matches (e.g. `important` not treated as `import`) ### Detached compile task (rapid-edit fix) - Compile operations (`ensure_deps` + `send_stateful` + `publish_diagnostics`) run as detached tasks via `loop.schedule()`, independent of the LSP request coroutine chain - LSP `$/cancelRequest` can no longer kill in-flight compilations — previously, cancellation would destroy the `ensure_compiled` coroutine frame, leaving `doc.compiling` permanently set and hanging all subsequent requests - `CompileGuard` RAII ensures `doc.compiling` is always cleaned up even if the detached task fails - Stale feature requests (where `ast_dirty` became true after compile finished) are dropped before forwarding to worker ### Other fixes - `signal(SIGPIPE, SIG_IGN)` on POSIX: prevents server crash when LSP client disconnects mid-write - `CompilationUnitRef::file_path()` / `deps()`: null-check `FileEntryRef` to prevent segfault on invalid FileID - `stateless_worker.cpp`: log BuildPCH diagnostic errors for debuggability - Default worker counts changed to 2 stateful + 3 stateless - `logging_dir` default changed to `.clice/logs` in config ### Tests - 19 unit tests for `is_preamble_complete` (incomplete `#include`, `import`, `export module`, mixed cases) - Integration tests: `test_include_completion.py` (5 tests), `test_import_completion.py` (4 tests), `test_rapid_edit.py` (2 tests), `test_pch.py` (4 new tests) - Smoke test: `rapid_edit.jsonl` — recorded VSCode session with 40 rapid edits + 61 cancel requests ## Test plan - [x] Unit tests: 463 passed - [x] Integration tests: 104 passed - [x] Smoke test (rapid_edit.jsonl): PASS - [x] Manual VSCode testing with `#include <iostream>` project 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
