The gopls 'package summary' pattern, applied properly: build the cross-
LSP CBMTypeRegistry ONCE per language at pipeline time (in a dedicated
cross_lsp_arena), share it READ-ONLY across all resolve workers via the
CBMCrossLspRegistries struct. Per-file work then becomes just tree-
sitter parse + AST walk + O(1) hash lookups — zero per-file registry
rebuilds for languages with a pre-built registry.
Each LSP gains two new public functions:
CBMTypeRegistry *cbm_<lang>_build_cross_registry(arena, defs, def_count)
— filters all_defs to its language, init + stdlib + registration
loop + cbm_registry_finalize, returns finalized registry.
void cbm_run_<lang>_lsp_cross_with_registry(arena, source, ...,
CBMTypeRegistry *reg, ...)
— skips the per-file build AND the per-file Phase 1b/1c AST scans
(those mutate the registry, which would race on a shared read-
only reg). Trade-off: a few file-local type aliases discovered
only by Phase 1b are missed; in practice the per-file extract
LSP already captured them via embedded_types/field_defs/etc.
Tested with parallel_python_lsp_override_cross_file_emits_lsp_
strategy_edges — fused + filtered + prebuilt path stays correct.
CBMLSPDef gains a CBMLanguage lang field set in pxc_build_lsp_def so
the per-language build functions can filter the global all_defs[].
cbm_parallel_resolve signature now takes CBMCrossLspRegistries* instead
of a single CBMTypeRegistry*. The resolve_worker dispatches:
cbm_pxc_registry_for_lang(lang) returns the right pre-built reg if any;
the worker then switch()es to the matching _with_registry variant.
Languages without a _with_registry variant fall through to the existing
filter + per-file build path.
Kubernetes (Go-heavy, 12k files, 139k defs) measured perf:
parallel_resolve: 5.51 min (strdup-removal baseline) -> 1.86 min
= 2.96x speedup
parallel.resolve.lsp_cross.slow lines: 1,258 -> 2
(-99.8%; the 2 remaining are Python files, not Go)
Peak RSS: 6.29 GB -> 6.23 GB (slight decrease — pre-built registry
shared, no per-file scratch)
All 3,616 tests pass; zod/serilog graphs exact match (per-file path
unaffected).
Cumulative trajectory from the original broken state on kubernetes:
35 min -> 19 min (finalize) -> 6.24 min (module-def filter) ->
5.51 min (strdup-removal) -> 1.86 min (Tier 2 Go) = 18.8x total.
Languages wired so far: Go, Python. C/C++, TS/JS, PHP, C# still use the
per-file filter+build path until their _with_registry variants land in
follow-up commits.
