DCO / dco (push) Has been cancelled
The per-file C cross-LSP resolver mutated the finalized, project-wide cross
registry that is shared read-only across the parallel resolve workers. Each
post-finalize add landed in a tail the hash index does not cover, so every
lookup linear-scanned an ever-growing tail -> O(files*defs) on large C
codebases. The Linux-kernel full index hung at "[4/9] Resolving" on 11 cores
for >6 min and never finished, plus a heap data race across workers.
Seal every shared cross-registry: CBMTypeRegistry gains a read_only flag, set
by all five {c,py,cs,ts,go}_build_cross_registry builders right after
finalize, and cbm_registry_add_func/_type no-op on a sealed registry. One
chokepoint guards every language, robust to any resolver mutation site. The
plain-C function-registration site is also skipped directly when the registry
is shared.
Add six cross-language invariant tests (c, c++, py, c#, ts, go): resolving
against a finalized shared registry must leave func_count/type_count
unchanged -- RED before the fix (C +1, C++ +2 post-finalize adds), GREEN
after.
Verified: full suite 5720 passed / 0 failed; Linux-kernel full index now
completes all 9 phases in 643s (4.88M nodes, 11.9M edges) instead of hanging
at phase 4.
