Unregister does NOT clear this: `sfltool dumpbtm` and the `registerLaunchItem: found existing item` log line both show the same item UUID across unregister+register, so re-registering only re-arms the same doomed constraint and burns another 10s ThrottleInterval per attempt. Only BTM's own `invalidateLaunchItem` clears the constraint, on its own schedule, and the item UUID changes when it does. Waiting longer for a spawn cannot help, because the job is killed on exec rather than running slowly. Diagnose an upgrade that comes up slowly by reading the BTM item UUID and the crash report, never by timing alone. +- DMG upgrades write `agent.rebind` and refuse to replace if the agent is still loaded. `AgentRebindPolicy` bounds how long the app waits before escalating; those waits only cover a job that is genuinely still spawning, not a constraint kill. - DMG and `/Applications/devctl.app` share a bundle id: never register the SMAppService agent from the volume copy, and never treat `openApplication` of Applications as success unless a different pid is actually running from that path (`createsNewApplicationInstance` plus a peer wait).

Outranking filesystem / Cursor Top Hits remains an Apple ceiling; do not chase without a new system API. - Machine-wide resource lock opt-in: locks are already path-scoped (`canonicalPath::resource`) and pause only that path's declarers. A rare shared system resource (one Docker Postgres, a fixed system daemon) may still want an explicit machine-wide scope so two projects serialize. Not the Cloudflare worktree pause case (that was misread against path-scoped keys); defer until a concrete cross-project shared-resource incident. -- `IntegrationTests` is a single `placeholder()` while `docs/design.md` promises a real end-to-end suite there (port-conflict from a second project, concurrent double-ensure). Those now live in `scripts/smoke.sh` and unit suites; either build the integration target out or retire the promise in the design doc. -- A restarting daemon is indistinguishable from a dead one for the length of `recoverAtStartup`, which is seconds when there is real state to restore. The listener only reaches `.ready` after restore, and the socket is unlinked in `ControlServer.init`, so clients get `daemon-unreachable` with ENOENT and nothing that says "starting". Moving the unlink later only changes the errno, since the daemon is unreachable either way: the fix is to answer during restore (bind early and reply "starting" to everything, or write a state file clients can read) so `devctl daemon status` can say restoring rather than down. Wanted because install/restart bounce servers, and an agent polling through that window sees a daemon that looks gone. +- A `stop` interleaved with concurrent `ensure` calls on the same server kills the calling process outright. Reproduction: against a real Router, ensure a server healthy, then run six tasks at once where one issues `server.stop` and the rest issue `server.ensure`. The process dies with no output, no crash report, and no assertion failure. Established so far: removing only the stop from that group makes the identical test pass, and it is not SIGTERM, because a handler installed in the test never fires, which points at SIGKILL or a hard abort. Both unrevalidated group signals are worth suspecting first, since `stop` sends `kill(-pid, SIGTERM)` without revalidation and `recordOutcome` can run for a previous run whose `pid` field a concurrent `start` has already replaced. Serious if it reproduces in the daemon rather than only in-process, since there it would mean devctld signalling its own group. - Split `CLI.swift`: every command struct lives in that one file, which is past the size where splitting is worth asking about. A structure decision, not drift; the codebase map describes the current layout. - Field-level config editing in the dashboard would preserve `devservers.json` formatting instead of normalizing writes. `devctl config init` writes indented JSON with sorted keys, so a recovered file and a dashboard-saved file now agree on shape, but a hand-authored one with its own ordering or comments still normalizes on save. -- `crashKillsSessionGrandchild` fails rarely: the session grandchild is still alive after the server turns crashed. Seen twice in roughly twenty full-suite runs on 2026-08-08, both while the machine was busy, and never in eight isolated runs or four quiet full runs. The test no longer sleeps a fixed slice over the sweep, it polls for five seconds, so a failure now means the descendant really survived that long rather than that the assertion was impatient. Suspect the crash exit path's descendant sweep racing a grandchild that has not yet been reparented. Reopen with a repro that names the surviving pid and its parent at the moment the sweep runs, before changing the sweep. -- Exact hashing above the file cap needs a streaming SHA-256. `SHA256Portable.digest` takes a whole `[UInt8]` with no incremental entry point, so a lock resource larger than 8 MiB is fingerprinted by head, tail, size, and mtime, and a middle-only rewrite that preserves all four escapes the identity check. The limit is asserted in `ResourceIdentityTests` and stated in the contract rather than left implicit. +- Unit-suite ports are hand-assigned literals inside the reserved 45000 to 45500 block, so adding a test means reading the others to find a free number and two suites can silently pick the same one. Leftovers from an interrupted run are now reaped on entry, which was the failure that actually bit; allocating from the block through one helper would close the collision half too. +- A directory lock resource still stops hashing contents past a byte budget, so a change confined to a file beyond it is missed while `exact: false` says the walk was partial. Raising or removing the budget is a cost decision that wants a measurement of real project state directories first, since the walk runs twice per guarded command; a single file has no such cap and is hashed whole. +- No end-to-end guard on the boot-restore ordering. The smoke gate asserts the invariant (a command racing restore succeeds and never reports the daemon unreachable) and prints whether it actually caught the window, but it would still pass if the listener went back to starting after restore, because waiting for the socket file to appear masks the difference. A discriminating version needs restore to take long enough to time, and it does not: `recoverAtStartup` returns once spawns have settled rather than once servers are healthy, so even a server that takes three seconds to bind leaves restore at roughly a tenth of a second. Reopen with a way to make restore reliably slow that is not a test-only knob in the daemon. - The identity check flags the risk window, not the damage: the flush that corrupts can land after the guarded command exits and the second capture is taken. Catching that would need the daemon to watch the resource across the whole hold, or to compare again once the paused set has resumed. +- Trust is recorded but never enforced. `recordTrustIfNeeded` only writes the flag, and no start-shaped path reads it: `recoverAtStartup` resolves specs through `mergedSpecs` and spawns a committed command for a project whose `trusted` flag is false. `sweepWatches` is the only caller of `registry.isTrusted` on an execution path and its own comment calls the check belt and braces. Deleting `isTrusted` entirely leaves `swift test` green, and every `RecoverAtStartupTests` case calls `setTrusted` in setup, so nothing can tell the requirement from its absence. `notTrusted` is a wire code no daemon code raises. Needs one gate every spawn path consults, plus a test that boots an untrusted project's config and asserts nothing spawns. +- `project.writeConfig` takes the project path raw: no `canonicalProjectPath`, no registry membership check, no trust check, and `AtomicFile.write` creates intermediate directories. A wire client can therefore drop a devservers.json at any path, and the raw key also desynchronizes `configCache`, which `loadConfig` keys canonically. +- Deliberate `stop()` has two of teardown's three halves. The session sweep added for the crash path is guarded by `if !stopRequested`, so a worker that left the process group and whose intermediate parent already exited survives `devctl stop`: the pre-signal snapshot is a live parent-chain walk that no longer reaches it, and the post-grace sweep runs after the root is gone. `lastDescendantSnapshot`, which would hold it, is not consulted by `stop()` either. Wants one `liveDescendants(rootPid:sessionID:snapshot:)` both paths call, so the answer to "how do we find escaped descendants" has one home. +- The crash teardown signals `-rootPid` and a whole session after `waitpid` has already reaped that pid, with `revalidate: false`. Every other signalling site in the repo revalidates against `ProcessIdentity` start time. A recycled pid therefore takes SIGTERM, and the session sweep widens the blast radius from one group to every process in that session. This is the shape the concurrent-stop entry above suspects. +- `daemon install` and `daemon restart` re-ensure inside the restore window and swallow it. `pollHello` asks `daemon.info`, which the restore gate deliberately answers, so readiness now means "accepting" rather than "serving"; `reensure` then sends `server.ensure` per server through a bare `DaemonClient` with `_ = try?`, so each `daemon-starting` refusal is dropped while the CLI reports the servers as bounced and back. Only `CLIRunner.awaitingRestore` learned to wait. Wants one readiness concept: a `pollHello` mode that polls `DaemonInfo.restoring` until it is absent. +- `groupUp` runs no `lockGate`, so `devctl up` starts a server declaring a held resource straight onto the locked state while `ensure` and `start` refuse it. The gate belongs in `prepareSpawn`, which every start-shaped path already funnels through, with an explicit bypass for lock resume rather than a fourth call site the next verb forgets. +- `restart --all` walks servers alphabetically and ignores `dependsOn`, while `up` and `down` resolve `DependencyGraph.waves`. A dependent can come back against a dependency that is about to be torn down. A throw part way also discards the `EnsureResult`s for servers already restarted, so the client cannot tell what moved. +- A `--grep` pattern is compiled and run with Swift's backtracking engine against every log line inside the `ServerSupervisor` actor, and `grepRejection` screens only for compilability. `^(a+)+$` against 18 characters takes seconds; a longer line is unbounded. The blocked actor is the supervisor, so health probes, `ensure`, `status` and `stop` for that server queue behind it, and `DaemonClient` sets no receive timeout, so the client blocks with it. Wants a match budget or a task-specific loop. +- `DaemonClient` does a blocking `read(2)` with no `SO_RCVTIMEO` and no deadline, so a wedged daemon hangs `devctl` with no output and no timeout, and in the app burns a cooperative-pool thread per stuck request. +- `AtomicFile.loadDefensively` returns the same nil for a missing file and a failed read, and `Registry.init` substitutes an empty store, which the next write persists over the real one. EMFILE is plausible here, since the daemon raises maxfiles precisely because it approaches the soft limit. A parse failure quarantines; a read failure should refuse to start rather than erase. +- A `.failed` that arrives after `startAccepting` has already resumed is only logged: `claim()` returns false, so nothing throws and nothing exits, leaving a live process serving nothing that KeepAlive will not relaunch because it has not exited. The never-resumes half of this entry is closed (there is now a deadline that throws naming the stuck listener state), but the post-ready half needs a different mechanism, since by then there is no continuation left to fail. +- `WatchPolicy` measures every window with wall-clock `Date`, alone in a codebase that uses `ContinuousClock` for stop grace and claim waits and clamps log timestamps monotonically. A backward clock step makes every past restart count as in-window, suspending the watch until an explicit restart, and stalls the quiet window; a forward step skips the settle window. +- An agent stuck at `requiresApproval` is retried every 15s and each retry force-opens System Settings, because `DaemonRecoveryPolicy.decide` never sees that state. `daemonNeedsApproval` also latches: `refresh` clears the stop-intent flag on a good poll but not this one, so once set it survives for the process lifetime and later renders an approval dead end for an already-approved agent. +- Vacuous checks that would not catch their own regression: `WatchTests.theKillSwitchStopsTheSweepEntirely` writes the watched file before any sweep arms a baseline, so it passes with the kill switch removed (its sibling `aWriteInsideTheSettleWindowDoesNotRestart` is the control proving it); `smoke-launchd.sh` gates on `daemon status | grep -q "pid"`, which matches launchd's own line while the daemon half says not responding; `smoke.sh`'s restore-window grep runs only against a payload the preceding check already proved successful, and discards the stderr line that is the only proof the wait happened; `HealthTests` asserts `recentLogTail != nil || lastExit != nil` one line after proving `lastExit` non-nil; `WorktreeCoexistenceTests` admits `observedPort == nil`; `LockParsingTests` checks the help contains `--`, which every option satisfies. +- The unit-suite reaper's reserved block is 45000 to 45500, but `ResourceLockTests` draws from 41000 and 42000, so a failure there leaks a fixture and a `sleep 1000` grandchild that nothing reaps, and `TestSupportTests` pins that gap as deliberate. `smoke.sh`'s exit trap goes the other way and `pkill -f` every fixture at the shared build path, killing a concurrent `swift test`'s children. +- `EventStore.query` decodes every line of `events.log` and its rotation before filtering by `since`, and `DaemonModel.surfaceCrashNotifications` polls it every 2s for the life of the app. Measured on a 5 MB / 40k-line file: 146ms whole-file against 2.0ms for a windowed read, same answer both ways. `post()` already clamps timestamps monotonically, so the file carries the invariant `LogQuery.firstLineIndex` and `lastLineTimestamp` search on; the fix is one shared windowed reader rather than a new mechanism. +- `LogQuery.run` reads and line-parses every file in the family even for `tail: 40` (measured 240ms whole-file against 1.7ms windowed on a 10 MB file, plus ~0.7us of ISO-8601 parse per line), and `markDate` calls it with neither `since` nor `tail`, which `eventsQuery --since-mark` then loops over every spec in the project. `lastLineTimestamp` already holds the windowed-read technique. +- `PortGuard` shells out to `/usr/sbin/lsof` and `/bin/ps` (measured 48.8ms per pair against a 2.3ms bare-subprocess control, so the cost is lsof's scan rather than launch), and `annotateLatentPortConflict` calls it synchronously inside the `Router` actor once per stopped server on every machine-wide status, which the app drives every 2s. Every other daemon request serializes behind it. The forward lookup maps onto `proc_pidfdinfo` (`libproc.h`, `PROC_PIDLISTFDS`/`PROC_PIDFDSOCKETINFO`) with no subprocess; the reverse `listenerPids(port:)` needs a full pid scan and may honestly stay a shell-out. Getting the blocking call off the actor is the larger half. +- `ServerStatus.recentLogTail` and `terminalEvidence` are the same fact assigned together at all four write sites, but only `terminalEvidence` is persisted, so after a daemon restart a crashed server has no `recentLogTail` and `status()` re-runs `spoolTail()` on every call, which the 2s machine-wide poll then repeats forever. `terminalEvidence` is also the more trustworthy of the two, since `recentLogTail` re-reads a spool an intervening `ensure` may have truncated. Collapsing them is a CLI JSON contract change (both are named in docs/cli-contract.md). +- `serverID` is minted in one place and split by hand at ten, two of them with `options: .backwards` and the rest forward, so a project path or server name containing `::` resolves one way in `recoverAtStartup` and the other in `why` and the watch sweep. Nothing rejects `::` in a server name. Wants a `ServerID` type whose `Codable` encodes to the flat string, so persisted keys are unchanged and no migration is needed, plus a config-validation clause making the ambiguity unauthorable. +- `ServerPhase` carries no derived predicates, so "holds its port", "needs attention" and "can start" are re-spelled at eight, five and two sites respectively, and the membership has already drifted: `prepareSpawn` treats `.stopping` as up while `targetOwnsPort` and `managedHolder` treat it as holding no port, and the menu bar's attention set omits the stale-spec and port-conflict cases that `AgentContext.isBadState` includes, so the popover dot stays dark for a server the agent context flags. Computed properties on `ServerPhase` in DevCtlKit would make each deviation visible instead of invisible. A concrete instance, raised by Copilot on PR #16 and confirmed by reading: `targetOwnsPort` returns true for a `.starting` server on its declared or effective port, and the caller then skips the `PortGuard.isListening` squatter check entirely, so an unmanaged listener is masked while the server is still starting and has bound nothing. `restartServers` runs that pre-check with `force: true` before it stops anything, which is exactly where an actionable `port-held` refusal turns into a spawn failure after the server is already down. `.starting` cannot be dropped from the set, because the comment above the call explains it is what stops a server that just won the single flight from reporting its own port as held: the phase means both "may own this port" and "may not have bound yet", and only `observedPort` separates them. Wants that distinction named before the membership is changed. +- `server.register` writes a spec straight to the registry without running `HealthCheckSpec.validationErrors()` or `PortClaim.configErrors`, which are called only from `ProjectConfigLoader.validate`. So one of the two ways a spec enters the daemon is checked and the other is not, and `config check` can call a project clean that `register` already poisoned. Wants a `ServerSpec.validationErrors()` on the type called from both entry points; note that `register` would start rejecting specs it currently accepts. +- `canonicalProjectPath` is a per-arm convention in `Router.handle` rather than a property of the decoded frame, and five arms omit it: `projectWriteConfig`, `logsQuery`, `logsMark`, `eventsQuery`, `serverWhy`. `EventStore.query` compares project strings raw, so a non-canonical spelling returns an empty feed silently, and `serverWhy` reads a log path that does not exist and answers with findings and no evidence. Not reachable from any shipped client today (the CLI, the app and deep links all canonicalize first), but the invariant is held by convention at fourteen sites and has already drifted at five. Normalizing once at the decode seam would also close the raw-path hole in `project.writeConfig` above. +- `doctor` re-derives machine-wide truth the daemon already computed and shipped: the squatter finding re-probes each port with fresh connect syscalls while `ServerStatus.portConflict`, populated by `annotateLatentPortConflict` for every status, goes unread by both the CLI and the app. Three answers to one question, and the menu bar never shows a conflict the daemon has already diagnosed. Wants a `daemon.doctor` wire method returning findings, with the CLI command becoming render-only. +- `switch` is the client-side stop-then-start that `restart`'s own doc comment condemns, over a longer window: `groupDown`, then `git switch`, then every `lifecycle["switch"]` argv to completion, then `groupUp`, with nothing holding the project across the gap. Another session's `ensure`, or the daemon's own watch sweep firing on the files the branch change rewrote, can start a server mid-install against a half-switched tree. `lifecycle` is also the one config field `validate` never touches, and `Switch` reaches it by discarding the validated view and re-decoding the raw file, so a project whose config the daemon would refuse still gets its committed argv executed. +- The app's 2s poll does avoidable work on the main actor: `SpotlightIndexer.sync` JSON-decodes the previously indexed entry map out of UserDefaults and rebuilds a sorted signature string before the guard that decides whether anything changed; `DaemonModel` and `DashboardView` construct a fresh `DaemonClient` (socket, connect, hello handshake) per call at seven sites rather than holding one; `LogsPane` re-requests with `tail: 400` and no `since` every second, which is the whole-file path in `LogQuery`, where `devctl logs --follow` already tracks `lastAt` and passes it. The LogsPane fix changes the pane from replacing to appending, so it wants rendering and viewing rather than landing blind. +- `SpoolTailer` opens, seeks and closes each spool ten times a second per stream per server, though its header comment claims one stat when idle. The rename hazard that correctly rules out an fd watcher for the config sweep does not apply, since the spool is opened once with `O_TRUNC` and never renamed, so `DispatchSource.makeFileSystemObjectSource` with `.extend` fits and `drain()` is already offset-based and idempotent. Keep a low-frequency backstop drain so a missed event cannot strand bytes. +- `ServerSupervisor.wait(for:timeoutSeconds:)` polls its own actor state every 100ms for a transition that same actor performs, putting a 100ms latency floor under every `ensure`, while `spawnWaiters`/`settleSpawnWaiters` one screen away is the right pattern. `phase` is assigned at thirteen sites; routing them through one `setPhase(_:)` that resumes phase waiters makes "a phase change without notifying waiters" unrepresentable and is the seam the poll stands in for. +- Two duplicated blocks worth collapsing before either side drifts: `ServerSupervisor.recordPortOwnership` and `recordObservedPort` each carry the same eighteen-line terminal-failure sequence (conflict, phase, spawnError, errorSummary, tail, evidence, cancel health, log, post event, and a registry write of the same four fields), so a new field recorded on failure has to be added twice; and `Router`'s `serverEnsure` and `serverStart` arms repeat the same seven-line resolve-canonicalize-trust-lockGate-prepareSpawn preamble, which is the path that enforces trust recording and the resource-lock gate before any spawn, so a gate added to one arm and not the other silently reopens the hole. +- The coverage gate cannot fail, so it certifies nothing. AGENTS.md states branch coverage stays above 80% on DevCtlKit and DevCtlDaemonCore and names `swift test --enable-code-coverage` as the command that prints the live figure. That command prints no figure, and the Swift toolchain emits no branch data at all: every row of `llvm-cov report`'s Branches column is zero, so the threshold is unmeasurable rather than merely unmeasured. Line coverage is available and currently reads 80.1% for DevCtlKit and 73.9% for DevCtlDaemonCore. Wants a decision on which metric the project actually gates on, then a script that prints it and exits nonzero below the line, since a standard nothing computes is one nobody can regress. +- Test-fixture setup has no home in two of the three targets: the scratch-temp-directory pair is hand-written in 22 files across `DevCtlDaemonCoreTests` and `DevCtlKitTests`, and "poll the supervisor until it reaches a phase" exists twice in one target under two names, two shapes and two sleep intervals (`HealthTests.pollPhase`, `SupervisorTests.waitForPhase`). `DevCtlKitTests` has no `TestSupport.swift` at all. diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md index 4e59e2a..4aa2b8c 100644 --- a/CONTRIBUTING.md +++ b/CONTRIBUTING.md @@ -25,7 +25,7 @@ Local path: `SIGN_IDENTITY="Developer ID Application: …" make dmg` then `scrip The session-context payload is harness-agnostic: `devctl context` prints a fenced plain-text block describing the current project's servers, and `devctl statusline` prints a one-line presence summary from statusline stdin JSON.

Conform to `HarnessAdapter` in `Sources/devctl/HookSupport.swift`: a `name` (the `--harness` value), the `settingsURL` of the file the harness reads, and an idempotent `install(devctlPath:)` that merges a session-start hook into that file without clobbering what is already there. Read and write it with the protocol's own `loadSettings()` and `writeSettings(_:)` rather than reaching for `Data(contentsOf:)`: `install` writes back everything it reads, so a read that answers "empty" for a file that exists turns the merge into a replacement of settings devctl does not own. `loadSettings` refuses a file it cannot parse for that reason, and returns an empty dictionary only when there is genuinely nothing there to lose. 2. If the harness wants a structured payload (as Claude Code does with `hookSpecificOutput.additionalContext`, or Cursor with `{additional_context}`), add a hidden subcommand like `HookClaudeSessionStart` / `HookCursorSessionStart` that adapts the `HookContext.render` output (a thin socket fetch over the pure `AgentContext.render` renderer in DevCtlKit) to that shape. Keep the guarantees: exit 0 always, fast, silent when there is nothing to say, never auto-starting the daemon, and never emitting raw log lines or command strings (child output and committed configs are attacker-influenceable). Resolve the session directory via `HookSessionCwd` (Cursor: `workspace_roots` / `CURSOR_PROJECT_DIR`; Claude: `cwd`). 3. Register the adapter in `harnessAdapters` and document the harness in `docs/cli-contract.md` under `devctl hook install`. diff --git a/Makefile b/Makefile index c578069..ec2d870 100644 --- a/Makefile +++ b/Makefile @@ -1,5 +1,9 @@ PREFIX ?= $(HOME)/.local -SIGN_IDENTITY ?= - +# Resolved lazily, so only the signing targets pay for the keychain lookup, and +# `make test` never does.

A worker forked in between was therefore in no snapshot at all, and since Foundation's `Process` puts every child in a new process group, the group-directed half could not reach it either. The result was a permanently orphaned descendant. The snapshot now also refreshes every 200ms while the server is still starting, which closes the common case, but a refresh is a scheduled task and a saturated machine can delay it past the crash, so timing alone cannot be the guarantee. + + (3) is that guarantee: a sweep for live processes in the run's session. `createSession = true` makes the root a session leader, a child that setpgid's out of the group still inherits the session, and session membership survives both the root exiting and the orphan reparenting to launchd, which is exactly where the parent chain goes blind. It is refused unless the session id equals the root pid and differs from the daemon's own session; without those two guards a root spawned without `createSession` would share the daemon's session and teardown would signal the daemon and every server it supervises.

It accepts throughout, though, and that split is deliberate: closing the socket for the duration met the first requirement and created a second problem, since a client got ENOENT and reported `daemon-unreachable`, which is exactly what a daemon that was never started looks like. An agent polling across an install or restart bounce therefore read a busy daemon as a dead one and moved to start another. The listener now comes up first and the router declines everything but `daemon.info` and `daemon.shutdown` with `daemon-starting` until restore returns, so the two states are distinguishable and only one of them warrants starting a daemon.

Sleep-aware: system power notifications (IORegisterForSystemPower) pause probes across sleep and reset failure counters with a wake grace window, so lid-open does not flap every server unhealthy. Timeouts use ContinuousClock; uptime derives from the recorded start wall-timestamp. - ControlServer: NWListener with `requiredLocalEndpoint = .unix(path:)`; single-instancing via the flock above; one Task per request so a slow `server.wait` never blocks the connection. Known cosmetic NECP log noise on unix listeners (Apple DTS-confirmed); not suppressed. `setrlimit` raises maxfiles to the hard limit at startup (launchd jobs default to a 256 soft limit, verified; a dozen servers plus subscribers approaches it) and doctor reports fd usage.
