From b399849bbd0f097dde5a1cfc1ce21c1a9d53b052 Mon Sep 17 00:00:00 2001 From: Sleyter Sandoval Date: Wed, 29 Apr 2026 14:17:12 -0500 Subject: [PATCH 1/4] fix(proposals): add timeouts to source fetches and fix unstable_cache nesting Without timeouts, hung RPC and HTTP calls (getBlockNumber, Blockscout pagination, Envio GraphQL) accumulate in the event loop during background revalidation, eventually starving the process and triggering a container restart. - Wrap getBlockNumber(config) with Promise.race + 10 s timeout in validate-source-sync.ts (both call sites) and get-proposals-from-the-graph.ts - Add AbortSignal.timeout(25_000) to each fetch() in the Blockscout while-loop pagination, matching the timeout used in the canonical Blockscout fetch module - Add AbortSignal.timeout(10_000) to the Envio GraphQL fetch - Add logger.error when a source returns [] (previously silent) and when all sources are exhausted - Fix triple-nested unstable_cache: fetchAllProposals now calls getProposalsFromBlockscoutUncached directly; transformProposalsIntoMap calls fetchAllProposals (raw) instead of getCachedProposals, so each cache wrapper only wraps raw functions Co-Authored-By: Claude Sonnet 4.6 --- .../actions/fetch-all-proposals.test.ts | 14 +++++++------- src/app/proposals/actions/fetch-all-proposals.ts | 14 ++++---------- src/app/proposals/actions/get-proposal-by-id.ts | 4 ++-- .../actions/get-proposals-from-blockscout.ts | 8 ++++++-- .../actions/get-proposals-from-envio.ts | 2 ++ .../actions/get-proposals-from-the-graph.ts | 9 ++++++++- .../proposals/actions/validate-source-sync.ts | 16 ++++++++++++++-- 7 files changed, 43 insertions(+), 24 deletions(-) diff --git a/src/app/proposals/actions/fetch-all-proposals.test.ts b/src/app/proposals/actions/fetch-all-proposals.test.ts index 117d2f7284..f663922a99 100644 --- a/src/app/proposals/actions/fetch-all-proposals.test.ts +++ b/src/app/proposals/actions/fetch-all-proposals.test.ts @@ -14,7 +14,7 @@ const hoisted = vi.hoisted(() => ({ fetchProposalsMock: vi.fn(), getProposalsFromEnvio: vi.fn(), getProposalsFromTheGraph: vi.fn(), -
