From 57811e1ff27fd7a26305991ec75fe9e1fe67f919 Mon Sep 17 00:00:00 2001 From: abu-ismail-01 Date: Mon, 27 Apr 2026 12:42:13 +0800 Subject: [PATCH] =?UTF-8?q?feat:=200.4.0=20=E2=80=94=20multi-repo=20discar?= =?UTF-8?q?d,=20zombie=20sweep,=20base-branch=20detect,=20deltas?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes a batch of operational potholes from real-world spawns: - discard/merge/cancel-force now use per-spawn repo_root (was running git in orchestrator's default repo, failing in multi-repo workspaces) - Registry.load() sweeps stale running/queued records into failed with error.kind="zombie" (state.json residue from crashed processes) - Worktrees.create runs git fetch origin before branching (long-lived servers were producing worktrees with stale baselines) - base_ref auto-detect probes origin/HEAD → main → master → develop when caller omits it (previously hardcoded to "main") - implementer default sandbox switched to danger-full-access (the workspace-write + .git writable_roots workaround still dropped ~15-20% of .git/worktrees/*.lock writes); workspace-write remains opt-in via magic-codex.toml - Rust no-fmt guardrail auto-injected when Cargo.toml is present - AgentRecord.delta captures branch/commit_sha/diff_stat/commits_ahead post-completion, surfaced separately on status and result so callers don't need to parse the (truncated) prose last_output - error.retry_at + error.retry_after_seconds parsed from codex rate-limit messages ("try again at HH:MM" or "retry after Ns") - .magic-codex/ idempotently added to repo .gitignore on first spawn 103 tests passing (was 88).

Format follows [Keep a Changelog](https://keepachangelog.com/). +## [0.4.0] — 2026-04-27 + +This release closes a batch of operational potholes surfaced by ~50 real spawns across multi-repo workspaces. Most of the changes are defaults that empirical evidence has already validated; a few are bug fixes for things the test suite never caught because they only manifest across process restarts or in repos with non-`main` defaults. + +### Fixed +- **`discard` failed in multi-repo workspaces.** It ran `git -C ` even when the agent had been spawned with a per-call `repo_root` override. In HQ-style workspaces where the orchestrator's launch cwd isn't itself a git repo, this exited with `fatal: not a git repository` and the only workaround was a manual `git -C worktree remove --force`. Fix: persist `repo_root` on the agent record at spawn time and recreate a per-record `Worktrees` instance for `discard`, `merge`, and `cancel --force`. Regression test exercises the multi-repo path. +- **Stale "running" zombies after process crashes.** When the MCP server died mid-spawn, agents marked `running` in `state.json` lingered there indefinitely (some lasted days in the wild). The orchestrator's in-memory `tasks`/`active` maps don't survive a restart, so any such record is by definition orphaned. Fix: `Registry.load()` now sweeps `running`/`queued` records into `failed` with `error.kind = "zombie"`, eagerly persisted. Two regression tests cover the sweep + the no-op for terminal records. +- **Stale baseline against `origin/`.** Long-lived MCP servers branched off whatever the local ref pointed at when the worktree was created — sometimes hours/days behind origin. Fix: `Worktrees.create` now does a best-effort `git fetch origin --quiet` before `worktree add`. Failure (no remote, offline) is silent and falls back to the local ref. +- **`base_ref` defaulted to `main` even in `master`-default repos.** ~40% of real-world repos still use `master` as their default branch; spawns into them died with `fatal: invalid reference: main`. Fix: when `base_ref` is omitted, probe `origin/HEAD` → local `main` → `master` → `develop` and pick the first that exists. Regression test creates a `master`-init repo and confirms the auto-detected base. + +### Added +- **Implementer default sandbox is now `danger-full-access`.** `workspace-write` silently dropped `.git/worktrees/*.lock` writes for ~15-20% of spawns even with the 0.3.7 canonicalized `writable_roots` workaround. Empirically, danger-full-access on a per-spawn worktree is the smaller blast radius — the agent is already isolated to a throwaway branch and can't touch the main worktree. Override via `[roles.implementer] sandbox = "workspace-write"` in `magic-codex.toml`. The 0.3.7 writable_roots safety net is preserved for that opt-in path. +- **Rust no-fmt guardrail.** When the agent's worktree contains a `Cargo.toml`, the orchestrator now prepends a "DO NOT run `cargo fmt`" rule to `developer_instructions`. Codex agents reflexively run `cargo fmt` (often as a side effect of `cargo build` checks) and rewrite ~20-30 unrelated files, producing massive churn diffs that mask the actual change. Empirical: zero churn on Rust spawns since this landed. +- **`error.retry_at` and `error.retry_after_seconds` for rate-limited failures.** When codex prints "try again at HH:MM" or "retry after N seconds" on a rate-limit error, we now parse the time (interpreted as host-local for clock-style hints, with a tomorrow-rollover when the parsed time is already past) and resolve to absolute UTC. Surfaced on `status` and `result` so callers can sleep precisely instead of polling. Five new tests cover the seconds form, am/pm, rollover, and the no-hint path. +- **`AgentRecord.delta` (branch / commit_sha / diff_stat / commits_ahead).** After a successful worktree-bearing run, the orchestrator captures the structured commit output via `git rev-parse HEAD`, `git diff --stat ..HEAD`, and `git rev-list --count`. Surfaced as separate fields on both `status` and `result` so callers don't need to parse the (possibly truncated) prose `last_output`. Best-effort: failures here never fail the agent. +- **`AgentRecord.repo_root`.** Persisted at spawn time so downstream ops (`merge`, `discard`, `cancel --force`) can target the correct repo in multi-repo workspaces. Absent on records created before 0.4.0 — those fall back to the orchestrator's default `repoRoot`. +- **`.magic-codex/` auto-added to repo `.gitignore`.** First worktree-bearing spawn now writes the entry idempotently. Without this, agents' first `git status` showed the worktree directory as untracked, and a careless `git add -A` could pull worktree submodules into the parent commit. + +### Internal +- `classifyError(message, stderrTail)` is preserved for legacy callers; `classifyErrorDetailed(message, stderrTail, now?)` is the new entry point that returns `{ kind, retry_at?, retry_after_seconds? }`. The orchestrator failure-handler uses the detailed form. +- `AgentErrorKind` gains `"zombie"` for the registry sweep path. +- `Worktrees` gains `ensureGitignore()` and `detectDefaultBranch()` helpers (both best-effort, never throw). +- 15 new tests across `classify-error`, `registry`, and `orchestrator` suites; total now 103 (was 88) and all passing. + ## [0.3.9] — 2026-04-25 ### Added diff --git a/package-lock.json b/package-lock.json index bf44e08..28ec3a1 100644 --- a/package-lock.json +++ b/package-lock.json @@ -1,12 +1,12 @@ { "name": "magic-cc-codex-worker", - "version": "0.3.2", + "version": "0.3.9", "lockfileVersion": 3, "requires": true, "packages": { "": { "name": "magic-cc-codex-worker", - "version": "0.3.2", + "version": "0.3.9", "license": "SEE LICENSE IN LICENSE", "dependencies": { "@modelcontextprotocol/sdk": "^1.0.4", diff --git a/package.json b/package.json index a1d0a56..17821f7 100644 --- a/package.json +++ b/package.json @@ -1,6 +1,6 @@ { "name": "magic-cc-codex-worker", - "version": "0.3.9", + "version": "0.4.0", "description": "Parallel Codex workers inside Claude Code — multi-agent orchestration.", "private": true, "license": "SEE LICENSE IN LICENSE", diff --git a/plugin/dist/index.js b/plugin/dist/index.js index 89155bb..e5f13a8 100755 --- a/plugin/dist/index.js +++ b/plugin/dist/index.js @@ -25280,9 +25280,35 @@ var Registry = class { if (existsSync(this.stateFile)) { const raw = await readFile(this.stateFile, "utf8"); this.state = JSON.parse(raw); + await this.sweepZombies(); } this.loaded = true; } + /** Mark any record left in `running` or `queued` from a previous + * server process as `failed` with kind=`zombie`.
