From 2255a0d2e2cde82fb03bf0754e9f3996f11348f8 Mon Sep 17 00:00:00 2001 From: ScriptedBro Date: Tue, 25 Aug 2026 10:14:52 +0100 Subject: [PATCH 1/2] feat: wire up Execution DAG engine and in-browser event search worker Wire the fully-built but disconnected DAG reconstruction engine into the application pipeline so Soroban cross-contract call trees are actually produced, persisted, analyzed, and visible in the UI. Wire the in-browser inverted-index event search worker into the dashboard so the live event feed has instant client-side full-text search. Execution DAG (Issue #8): - Enhance DagNode types with authorizedBy, reentrancyDetails, authTraces - Implement stack-based reentrancy detection with full call path tracking - Implement auth tracing to attribute Stellar accounts to DAG nodes - Add ExecutionDag Prisma model with migration support - Wire onDag callback in server.ts and worker/indexer.ts for persistence - Create GET /api/v1/dag API route with txHash, id, ledger, reentrancy queries - Build interactive DagPanel visualization with collapsible nodes, reentrancy highlighting, auth badges, and contract filtering - Replace placeholder DAG page with real transaction search and visualization Event Search Worker (Issue #9): - Add ADD_EVENTS/REMOVE_EVENTS message types to event search worker - Add addEvents/removeEvents/destroy to EventSearchClient wrapper - Create useEventSearch hook with debounced search and incremental indexing - Wire client-side full-text search into DashboardClient alongside server search - Worker properly cleaned up on component unmount Tests: - 16 reentrancy detection tests: positive (direct, chain, self, multi-branch), negative (sequential, deep linear, separate branches, system fn, empty), and edge cases - 7 event search hook tests: worker lifecycle, debounce, index building, incremental updates, search results, clear results Closes #408 --- app/api/v1/dag/route.ts | 87 ++++++ app/dag/page.tsx | 172 +++++++---- app/dashboard/DashboardClient.tsx | 172 ++++++++--- components/dag/DagPanel.tsx | 422 ++++++++++++++++++++++++-- lib/dag/engine.test.ts | 325 ++++++++++++++++++++ lib/dag/engine.ts | 343 ++++++++++++++++++--- lib/dag/persistence.ts | 166 ++++++++++ lib/dag/types.ts | 42 +++ lib/hooks/useEventSearch.ts | 205 +++++++++++++ lib/stellar/indexer.ts | 2 + lib/workers/eventSearch.worker.ts | 174 ++++++++++- lib/workers/eventSearchClient.test.ts | 230 ++++++++++++++ lib/workers/eventSearchClient.ts | 60 +++- package-lock.json | 11 +- package.json | 1 + prisma/schema.prisma | 26 ++ server.ts | 14 + src/worker/indexer.ts | 14 + 18 files changed, 2290 insertions(+), 176 deletions(-) create mode 100644 app/api/v1/dag/route.ts create mode 100644 lib/dag/engine.test.ts create mode 100644 lib/dag/persistence.ts create mode 100644 lib/hooks/useEventSearch.ts create mode 100644 lib/workers/eventSearchClient.test.ts diff --git a/app/api/v1/dag/route.ts b/app/api/v1/dag/route.ts new file mode 100644 index 0000000..645a22a --- /dev/null +++ b/app/api/v1/dag/route.ts @@ -0,0 +1,87 @@ +/** + * Execution DAG API + * + * GET /api/v1/dag?txHash= — Fetch DAG by transaction hash + * GET /api/v1/dag?id= — Fetch DAG by database ID + * GET /api/v1/dag?ledger= — Fetch DAG by ledger sequence + * GET /api/v1/dag?reentrancy=true — List recent reentrancy-flagged DAGs + */ + +import { NextRequest, NextResponse } from "next/server"; +import { authenticateAndRateLimit } from "@/lib/api/middleware"; +import { toErrorResponse, validationErrorResponse } from "@/lib/api/error-response"; +import { + getExecutionDagByTxHash, + getExecutionDagById, + getExecutionDagByLedger, + listReentrancyDags, +} from "@/lib/dag/persistence"; + +export async function GET(request: NextRequest): Promise { + const authError = await authenticateAndRateLimit(request); + if (authError) return authError; + + const { searchParams } = new URL(request.url); + const txHash = searchParams.get("txHash"); + const id = searchParams.get("id"); + const ledger = searchParams.get("ledger"); + const reentrancy = searchParams.get("reentrancy"); + + try { + // List reentrancy-flagged DAGs. + if (reentrancy === "true") { + const limit = Math.min( + parseInt(searchParams.get("limit") ??

Coming Soon

-

- The Call Tree (DAG) visualization is currently being built. This feature will allow you - to: -

-
    -
  • - - View nested contract calls as a hierarchical tree structure -
    • -
  • - - Trace authorization and require_auth chains across contracts -
    • -
  • - - Identify reentrancy patterns and execution dependencies -
    • -
  • - - Filter by contract, function, and call depth -
    • -
-

- Check back soon for updates. Follow our{" "} - - GitHub repository - {" "} - for development progress. -
