From b3b451fd282af5d2b24f697f8de499b6b8cababf Mon Sep 17 00:00:00 2001 From: CodeGhost21 <164498022+CodeGhost21@users.noreply.github.com> Date: Wed, 22 Apr 2026 18:17:39 +0530 Subject: [PATCH] fix(composio): keep chat integrations cache in sync on Windows (#749) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On Windows the `ComposioConnectionCreated` → `wait_for_connection_active` invalidation path often misses: the 60 s readiness poll can expire before the user finishes the hosted OAuth flow (Defender SmartScreen, slower browser launch, extra consent dialogs), so `invalidate_connected_integrations_cache` never fires and the chat runtime stays frozen on the pre-connect snapshot while Settings correctly shows "Connected" via its 5 s `listConnections` poll. Layer two cross-platform defenses on top of the existing event-bus path: 1. `composio_list_connections` (the RPC the UI polls every 5 s) now diffs the backend's active-toolkit set against every cached entry and invalidates on divergence, so chat converges to truth within one poll interval — regardless of how the OAuth round-trip completed. 2. Add a 60 s TTL on the `INTEGRATIONS_CACHE` so stale entries can't live forever even if nothing polls. 3. Grep-friendly `[composio][integrations]` logs at every decision point (cache hit / miss / expiry / divergence diff) for quick diagnosis from user-supplied debug dumps. Also covers the regression with six new unit tests (activate, disconnect, steady state, non-active rows, CONNECTED vs ACTIVE alias, TTL expiry) serialized via a shared test mutex so they don't race the existing mock-backend tests over the process-wide cache. --- Cargo.lock | 2 +- src/openhuman/composio/ops.rs | 403 ++++++++++++++++++++++++++++++++-- 2 files changed, 389 insertions(+), 16 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index a2379a3dd..d2a3bac32 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -4420,7 +4420,7 @@ checksum = "c08d65885ee38876c4f86fa503fb49d7b507c2b62552df7c70b2fce627e06381" [[package]] name = "openhuman" -version = "0.52.27" +version = "0.52.28" dependencies = [ "aes-gcm", "anyhow", diff --git a/src/openhuman/composio/ops.rs b/src/openhuman/composio/ops.rs index e30fe5288..d611a413e 100644 --- a/src/openhuman/composio/ops.rs +++ b/src/openhuman/composio/ops.rs @@ -81,6 +81,13 @@ pub async fn composio_list_connections( .filter(|c| matches!(c.status.as_str(), "ACTIVE" | "CONNECTED")) .count(); let total = resp.connections.len(); + // Reconcile the chat-runtime integrations cache against this fresh + // snapshot.
