From fe7f191cb983af5046a20b6658f461a709525639 Mon Sep 17 00:00:00 2001 From: Molecule AI SDK-Dev Date: Tue, 21 Apr 2026 06:51:45 +0000 Subject: [PATCH] feat(tests): GAP-05 add _get_with_retry() with 429 back-off + fix broken test_call_peer_errors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds retry-on-429 with exponential back-off (1 s → 2 s → 4 s, ±25% jitter, 30 s cap, Retry-After header honoured) to all idempotent RemoteAgentClient GET calls: poll_state, pull_secrets, get_peers, discover_peer. Also fixes the merged test_call_peer_errors.py (PR #7) which was broken: - Removed pytest-mock dependency (mocker not installed) - Fixed call_peer(message: str) vs dict - Fixed non-existent _call_direct/_call_proxy method patches - Uses FakeResponse + _session.post.side_effect pattern consistently Adds tests/conftest.py (FakeResponse + client fixture + _CaptureHandler) and tests/test_retry_backoff.py (18 new tests).
