From 1c9580e89b40690e1d4b02330d391d7ea4cb2b12 Mon Sep 17 00:00:00 2001 From: Nicky Leach Date: Thu, 3 Sep 2026 12:53:57 -0700 Subject: [PATCH 1/3] test(acpx): bind ACPX credential waits to the real retry envelope (#12780) ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The ACPX runtime host tests manage credentials and sandbox operations. > - These tests poll operations that can join quarantine recovery. > - Recovery uses real backoff and directory synchronization, so the default poll deadline can expire while the operation makes progress. > - Three tests also stage a contender before the kernel lease release completes. > - This pull request binds every relevant poll and staging call to the documented retry envelope. > - The benefit is more stable tests and error output that names the last observed cause. ## Linked Issues or Issue Description **What happened?** Under concurrent test load, ACPX runtime host tests failed while credential recovery still made progress. Three tests also saw an active lease after they removed `auth.json`. **Expected behavior** The tests must wait for the documented retry envelope before they report a failure. They must stage a contender only after the credential lease becomes available. **Steps to reproduce** 1. Run `npx vitest run src/drivers/acpx/` from `packages/paperclip-runner`. 2. Run the suite under high concurrent load. 3. Observe intermittent timeout or active-lease failures in `runtime-host.test.ts`. **Paperclip version or commit** `865b4854fb44d3689f1c0ff17e3e715d52aaea73` base commit. **Deployment mode** Built from source. **Installation method** Built from source. **Agent adapter(s) involved** ACPX Codex runtime host tests. **Database mode** Not database-related. **Access context** Unclear / not applicable. **Node.js version** Not recorded in the handoff. **Operating system** Not recorded in the handoff. **Relevant logs or output** Under concurrent load, the failure included `Timed out in waitFor!` after 1157 ms and `Managed Codex credential home already has an active lease`. **Relevant config (if applicable)** Not applicable. **Additional context** The change touches test code only. It adds no test, removes no test, and weakens no assertion. The file keeps 28 tests and 146 assertions. ## What Changed - Add a test-local wait helper with an explicit 10-second deadline. - Apply the helper to every credential and sandbox poll in `runtime-host.test.ts`. - Report the last observed error when a poll reaches its deadline. - Guard the three credential staging calls that could race with lease release. - Set a 20-second timeout on tests that use the long wait. ## Verification - `npx vitest run src/drivers/acpx/runtime-host.test.ts` passes all 28 tests on the change branch. - A 40-run concurrent comparison produced zero `runtime-host.test.ts` failures on the change branch. - The base comparison produced 13 `runtime-host.test.ts` failures across 40 runs. - The broader ACPX suite still has a separate `codex-credentials.test.ts` flake on both arms. - CI and Greptile results will provide the remaining merge checks. ## Risks Low risk. The change affects test synchronization only. It increases selected test wait limits and does not change product behavior. ## Model Used OpenAI Codex, GPT-5. The model used tool calls and code execution. The runtime did not provide a context window value. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes: #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and recorded the separate ACPX suite flake above - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip --- .../src/drivers/acpx/runtime-host.test.ts | 211 ++++++++++++++---- 1 file changed, 171 insertions(+), 40 deletions(-) diff --git a/packages/paperclip-runner/src/drivers/acpx/runtime-host.test.ts b/packages/paperclip-runner/src/drivers/acpx/runtime-host.test.ts index 8ec2e7cbdc..b5e714b066 100644 --- a/packages/paperclip-runner/src/drivers/acpx/runtime-host.test.ts +++ b/packages/paperclip-runner/src/drivers/acpx/runtime-host.test.ts @@ -25,6 +25,131 @@ const admissionControllers: AbortController[] = []; const pendingAdmissionOpenings = new Set>(); const pendingAdmissionCleanups = new Set>(); +// A credential or sandbox poll in this file can run behind a real retry +// envelope, not a mocked one. `stageManagedCodexCredential` first joins any +// in-flight quarantine recovery (codex-credentials.ts:183, :610-625).

The sleeps sometimes ran before a provider write or after a queued write entered. The tests then failed or missed a broken lock. **Expected behavior** The tests must wait for real provider-write events and must detect a queued write that enters before the first write finishes. **Steps to reproduce** 1. Run `npx vitest run server/src/__tests__/secrets-service.test.ts`. 2. Repeat the test file under sustained load. 3. Remove the write lock and run the concurrency tests. 4. Observe intermittent timing failures or missed lock failures. **Paperclip version or commit** `13bff0adee0216ee9ec67c843e9ead94aa788c68` **Deployment mode** Local dev (`pnpm dev`) **Installation method** Built from source (`pnpm dev` / `pnpm build`) **Agent adapter(s) involved** Not adapter-specific (core test) **Database mode** Not database-related **Additional context** This pull request changes tests only. It does not change production code. ## What Changed - Wait for a deferred signal when the first operation reaches its provider write. - Measure an uncontended provider-write duration and use a safety multiple for the queued-write check. - Release the test gate in a `finally` block so failed assertions do not leave a write active. - Throw when the measurement helper does not observe the provider write. ## Verification - `npx tsc --noEmit -p server/tsconfig.json` reports no errors in the changed file. - `npx vitest run server/src/__tests__/secrets-service.test.ts` passes 90 of 90 tests. - The engineer ran the test file five times under sustained load, and all runs passed. - Full CI must pass after this pull request starts. ## Risks Low risk. The change affects test code only. The measured wait can expose a real lock regression, but it does not change runtime behavior. ## Model Used OpenAI Codex, GPT-5, tool use and code execution. The exact context window and reasoning mode are not exposed by the runtime. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes: #` / `Refs: #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip --- server/src/__tests__/secrets-service.test.ts | 405 ++++++++++++++++--- 1 file changed, 354 insertions(+), 51 deletions(-) diff --git a/server/src/__tests__/secrets-service.test.ts b/server/src/__tests__/secrets-service.test.ts index 53e73b2ff8..dbc6050fdf 100644 --- a/server/src/__tests__/secrets-service.test.ts +++ b/server/src/__tests__/secrets-service.test.ts @@ -4,6 +4,7 @@ import { mkdir, rm } from "node:fs/promises"; import os from "node:os"; import path from "node:path"; import { afterAll, afterEach, beforeAll, describe, expect, it, vi } from "vitest"; +import type { MockInstance } from "vitest"; import { and, eq } from "drizzle-orm"; import { resolveCodexAuthCacheDir, withAccountHomeSecretMutationLock } from "@paperclipai/adapter-codex-local/server"; import { @@ -37,6 +38,112 @@ if (!embeddedPostgresSupport.supported) { ); } +// A deferred promise: a concurrency test resolves `resolve` from inside a +// mocked call, then a waiter `await`s `promise`.

Describing the bug in-PR using the bug-report fields: **What happened?** After a deploy that changes the app bundle but not `sw.js`, tabs left open across the upgrade keep running the old bundle indefinitely. The network-first service worker means a manual reload always recovers, but nothing triggers that reload automatically. Concretely, the `2026.831.1` onboarding fix did not reach tabs that were open on `2026.831.0`. **Expected behavior** When a new bundle is deployed, the existing update machinery (`registration.update()` on visibility/interval, reload on `controllerchange`) should bring parked tabs onto the new bundle without a manual reload. **Steps to reproduce** 1. Open the app and leave the tab open. 2. Deploy a build that changes the app bundle but not `sw.js` (the common case — `sw.js` was static). 3. Observe the open tab keeps running the previous bundle; no new worker installs, so no `controllerchange` and no reload. **Paperclip version or commit** Reproduced against `2026.831.1` and `master` before this change. **Deployment mode** Any web deployment that serves the built UI (local trusted quickstart, managed, or self-hosted). Related PRs (searched open + closed before opening this one): - Refs #12198 (merged) — added the parked-tab `update()`/`controllerchange` reload logic this PR completes by making `sw.js` actually change per deploy. - Refs #9951 (open) — an alternative "prompt to reload on new build" approach to the same problem; this PR instead reuses the existing silent auto-reload path. Reviewers may want to pick one. - Refs #8112 (open) — serves `sw.js` with `no-cache`; complementary (that keeps the worker script itself fresh; this makes the script vary per build). ## What Changed - `ui/public/sw.js`: derive `CACHE_NAME` from a `__PAPERCLIP_BUILD_ID__` placeholder so the worker source varies per build. - `ui/src/lib/vite-sw-build-id.ts`: new Vite build plugin that rewrites the placeholder in the emitted `sw.js` with the entry chunk's content hash (stable when the app is unchanged, new when it changes). Throws if the placeholder is missing, so the worker can never silently stop rotating. - `ui/vite.config.ts`: register the plugin. - `ui/src/lib/vite-sw-build-id.test.ts`: unit tests for the stamping helper, the build-id derivation, and a contract test that `public/sw.js` still carries the placeholder. ## Verification - `vitest run ui/src/lib/vite-sw-build-id.test.ts` — 7 tests pass. - `vite build` — the emitted `dist/sw.js` contains `BUILD_ID = "index-"` matching the entry chunk `dist/assets/index-.js`, and the `__PAPERCLIP_BUILD_ID__` placeholder is gone. A subsequent build with unchanged app code produces the same id (no needless worker churn); a build with changed code produces a new id. - Dev (`vite serve`) leaves the literal placeholder in `sw.js`, where HMR (not the worker) drives refreshes. ## Risks - Low risk, build-time only. No runtime service-worker logic changes beyond the cache name being build-specific; the activate handler already deletes all caches, so a rotating name is inert there. - If a future edit removes the placeholder, the build fails loudly rather than silently shipping a non-rotating worker. ## Model Used - Claude (Anthropic), model id `claude-fable-5` (Claude Fable 5), used with tool use, shell commands, file editing, and test execution. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --- ui/public/sw.js | 9 +++- ui/src/lib/vite-sw-build-id.test.ts | 63 ++++++++++++++++++++++ ui/src/lib/vite-sw-build-id.ts | 81 +++++++++++++++++++++++++++++ ui/vite.config.ts | 3 +- 4 files changed, 154 insertions(+), 2 deletions(-) create mode 100644 ui/src/lib/vite-sw-build-id.test.ts create mode 100644 ui/src/lib/vite-sw-build-id.ts diff --git a/ui/public/sw.js b/ui/public/sw.js index e5997304dc..9a9d1a7ee6 100644 --- a/ui/public/sw.js +++ b/ui/public/sw.js @@ -1,4 +1,11 @@ -const CACHE_NAME = "paperclip-v2"; +// The build id is stamped into this file at production build time (see +// stampServiceWorkerBuildId in vite.config.ts), so a deploy that changes only +// the app bundle still changes sw.js byte-for-byte.
