Bundles the working-tree state from the prior session (PR 0 bench harness,
PR 1a audit_actor_id removal, PR 1b WriteQueueManager + writer integration)
together with the first half of PR 2's interior-mutability foundation
(catalog and schema_source wrapped in Arc<ArcSwap<...>>). The two streams
intermix in 7 of the same files, so splitting via git add -p was
impractical. Subsequent PR 2 steps land as separate atomic commits.
PR 0 — server-level concurrent /change bench harness
- crates/omnigraph-server/examples/bench_concurrent_http.rs (new)
- .context/bench-results/{baseline-main,after-pr1}/ (gitignored)
PR 1a — drop the audit_actor_id field, thread per-call
- removed Omnigraph::audit_actor_id and the swap-restore patterns in
mutation.rs, merge.rs, loader/mod.rs
- actor_id: Option<&str> threaded through MutationStaging::finalize,
mutate_with_current_actor, ingest_with_current_actor,
branch_merge_impl, branch_merge_on_current_target,
commit_prepared_updates*, record_merge_commit,
commit_updates_on_branch_with_expected
- apply_schema and ensure_indices_for_branch pass None (system-attributed)
PR 1b — per-(table_key, branch) write queue + revalidation + sidecar
- new crates/omnigraph/src/db/write_queue.rs with WriteQueueManager,
acquire/acquire_many, sorted+deduped acquisition; 6 unit tests
- Arc<WriteQueueManager> field on Omnigraph + db.write_queue() accessor
- MutationStaging::finalize split into stage_all (Phase A, no queue)
and StagedMutation::commit_all (Phase B, acquire_many + revalidate
pins + sidecar + commit_staged); guards held across publisher
- delete-only mutations now emit recovery sidecars; revalidation
extended to inline_committed tables
- branch_merge_on_current_target, apply_schema_with_lock, and
ensure_indices_for_branch acquire per-table queues for their
touched tables
PR 2 Step B (partial) — catalog and schema_source via ArcSwap
- catalog: Catalog -> Arc<ArcSwap<Catalog>>
- schema_source: String -> Arc<ArcSwap<String>>
- public accessors return Arc<Catalog> / Arc<String>; readers bind
locally where the borrow has to outlive an expression
- new pub(crate) store_catalog / store_schema_source helpers replace
the field assignments in apply_schema and reload_schema_if_source_changed
- 117 tests across lifecycle/end_to_end/branching/runs pass; engine
lib + workspace compile clean
Coordinator wrap (Mutex) and the &mut self -> &self engine API
conversion follow in subsequent commits.
