From 21a5c31b85676105710e32e3670485bdbaede578 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-BE Date: Sat, 9 May 2026 21:52:09 +0000 Subject: [PATCH 01/14] [core-be-agent] fix: Treat delivery-confirmed proxy errors as delegation success MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two-part fix for issue #159 — successful delegation responses were rendered as error banners: PART 1 — a2a_proxy.go: When io.ReadAll fails mid-stream (e.g., TCP connection drops after the agent sent its 200 OK response), the prior code returned (0, nil, BadGateway) discarding both the HTTP status code and any partial body bytes already received. Fix: return (resp.StatusCode, respBody, error) so callers can inspect what was delivered even when the body read failed. PART 2 — delegation.go: New condition in executeDelegation after the transient-error retry block: if proxyErr != nil && len(respBody) > 0 && status >= 200 && status < 300 { goto handleSuccess } When proxyA2ARequest returns a delivery-confirmed error (status 2xx + non-empty partial body), route to success instead of failure. This prevents the retry-storm pattern where the canvas shows "error" with a Restart-workspace suggestion even though the delegation actually completed and the response is available. Regression tests (delegation_test.go): - TestExecuteDelegation_DeliveryConfirmedProxyError_TreatsAsSuccess: server sends 200 + partial body then closes; second attempt succeeds. Verifies the new condition fires for delivery-confirmed 2xx responses. - TestExecuteDelegation_ProxyErrorNon2xx_RemainsFailed: server sends 500 + partial body then closes. Verifies non-2xx routes to failure. - TestExecuteDelegation_ProxyErrorEmptyBody_RemainsFailed: server returns 502 Bad Gateway (empty body, transient). Verifies empty-body errors still route to failure (condition len(respBody) > 0 guards it). - TestExecuteDelegation_CleanProxyResponse_Unchanged: clean 200 OK. Verifies baseline (proxyErr == nil path) is unaffected. Fixes issue #159.

Extracts the inline `(proxyErr != nil && len(respBody) > 0 && 2xx)` predicate into a named helper `isDeliveryConfirmedSuccess`. Same behavior; the call site now reads `if isDeliveryConfirmedSuccess(...)`. 2.

The bug: platform_auth._cached_token is populated at module import or first get_token() call and persists for the process lifetime. Tests that use monkeypatch.delenv("MOLECULE_WORKSPACE_TOKEN") to simulate "no token in env" were failing because delenv removes the env var but not the module-level cache — subsequent get_token() calls returned the stale cached value. Fix: add a function-scoped autouse fixture in conftest.py that calls platform_auth.clear_cache() before every test. The import is inside the fixture to avoid collection-time import issues when platform_auth is not yet available.

Position is persisted to the backend via savePosition. - The modal-dialog guard (same pattern as ? shortcut) prevents Arrow keys from moving nodes when a modal like KeyboardShortcutsDialog is open — dialogs own their own arrow semantics. - All shortcuts guarded by the inInput check so Arrow keys still work for text navigation inside inputs/textareas. Changes: - canvas.ts: new moveNode(dx, dy) store action — updates position directly without the grow-parents pass that onNodesChange runs on every drag tick (avoids edge-chase flicker). - useKeyboardShortcuts.ts: Arrow key handler added. - canvas.test.ts: new moveNode unit tests (position update, no-op, savePosition call). - useKeyboardShortcuts.test.tsx: new integration tests for all keyboard shortcuts including the new Arrow key handlers. - canvas-audit-items.md: Keyboard Shortcuts section upgraded to ✅, drag item marked done. - canvas-events.test.ts: fix pre-existing double-}); syntax error.

Fix: check os.Getuid() == 0 at the start of the test and skip with a clear message.

Root cause: two cooperating bugs in the sweeper test harness. 1. Sweeper loop called sweepOnce after ctx cancellation (double-increment). When ctx was cancelled the loop's select received ctx.Done(), called sweepOnce with the cancelled ctx, storage.Sweep returned context error, and metrics.PendingUploadsSweepError() incremented the error counter a SECOND time before the loop exited. Subsequent tests captured a polluted error baseline and their deltaError assertions failed. 2. Tests called defer cancel() without waiting for the goroutine to exit. The goroutine could still be blocked on Sweep (waiting for the next ticker's C channel) when the next test called metricDelta(). If the goroutine's Sweep returned during the next test's measurement window, the shared metric counters mutated mid-baseline. Fix (production code): - Guard the ticker arm: if ctx.Err() != nil, continue instead of calling sweepOnce. This prevents the post-cancellation sweep from running. Fix (test harness): - startSweeperWithInterval gains a done chan struct{} parameter. When the loop exits the channel is closed exactly once. - StartSweeperForTest starts the goroutine and returns the done channel, allowing tests to drain it with <-done after cancel() — guaranteeing the goroutine has fully terminated before the next test's baseline. All 8 sweeper tests now use StartSweeperForTest and drain the done channel before returning, ensuring stable metric baselines across the full suite.
