## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The restart-chaos harness downloads the signed Daytona runner image with skopeo before each Daytona wave > - #20021 made a failed copy retry from an empty directory, but the retry only runs when skopeo exits > - A hung blob read never exits, and a Daytona pull stalled for 80 minutes > - This pull request bounds each copy attempt, so a stall is killed and retried > - The benefit is that one network stall costs at most one bounded attempt, not the whole run ## Linked Issues or Issue Description Follow-up to #20021. No duplicate PR was found. **What happened?** A Daytona chaos run's image pull stalled inside `skopeo copy` for 80 minutes, even after #20021. `copyImageToDir` awaited `execFile` with no timeout, so a read that hung forever blocked the run forever. **Expected behavior** Each copy attempt has a time bound. A stalled attempt is killed and the next attempt starts from an empty directory. **Steps to reproduce** 1. Run a Daytona wave or crash point with an uncached image on a network where a registry blob read hangs. 2. Before this PR, `skopeo copy` never returns and the run waits indefinitely. **Paperclip version or commit** `master` before this PR. ## What Changed - `copyImageToDir` passes `timeout` (default 20 minutes, `RESTART_CHAOS_SKOPEO_ATTEMPT_TIMEOUT_MS`) and `killSignal: "SIGKILL"` to each `skopeo copy`. A timed-out attempt counts as a failed attempt and retries from an empty directory. - README updated. ## Verification - New test: a fake skopeo that writes a partial blob and then hangs is killed after the 500 ms test bound, and the second attempt succeeds, within 10 s. - `pnpm exec vitest run --config tests/restart-chaos/vitest.config.ts tests/restart-chaos/daytona-image.test.ts`: 18/18. `tsc -p tests/restart-chaos/tsconfig.json` is clean. ## Risks - Test harness only. A very slow but progressing pull longer than 20 minutes would now be retried; the bound is configurable. ## Model Used - Anthropic Claude Opus 5.5 (`claude-opus-5-5`), via Claude Code with tool use. ## 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 - [ ] 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
