Fix: Set an explicit TimeoutStopSec on the Linux service unit - #1079
Conversation
The rendered systemd unit set no TimeoutStopSec, so `systemctl --user stop` relied on systemd's undocumented default (90s) to exceed the proxy's own 15s graceful-shutdown deadline. Make that margin explicit at 20s, matching the headroom the macOS supervisor already gives the same proxy shutdown before it insists with a kill. Verified by build/vet/gofmt and an extended TestRenderUnit_BothPlatforms assertion. Not yet verified against a real systemd — no integration test drives a live `systemd --user` session for this repo's Linux path.

CodeRabbit review on #1079: the prior assertion only checked that a TimeoutStopSec key existed, via strings.Contains — a regression to TimeoutStopSec=5 (or any value <=15) would satisfy it while defeating the entire point of setting the value explicitly. Parse the value and require it to exceed 15 (the proxy's own graceful- shutdown deadline, main.go), rather than pinning to the literal 20: that's the actual invariant this constant exists to satisfy, and it won't false-fail if the value is later deliberately tuned. Verified by temporarily setting TimeoutStopSec=5 in renderUnitFor and confirming the test fails with a clear message, then reverting.

The parser added to address CodeRabbit's finding was more machinery than a one-line production fix warrants: nothing requires this value to be flexible, and if it's ever deliberately changed, updating one test literal is trivial. Testing the literal value directly is simpler and equally effective. Replace it with strings.Contains(u, "TimeoutStopSec=20\n") — the trailing newline avoids matching TimeoutStopSec=200/201 etc. Still verified to fail on a mutated TimeoutStopSec=5 and pass on 20.

Small, well-scoped fix. TimeoutStopSec=20 is well-justified against the proxy's 15s drain deadline and mirrors the macOS supervisor's existing headroom, and the new test assertion pins the exact value so a future regression fails loudly. No must-fix issues (not approving since this is my own PR).

nit: this rationale comment is 9 lines for a single config line. Consider trimming to the core claim (20s > proxy's 15s drain, matches the macOS supervisor's wait) and leaving the "why not rely on systemd's default" aside for the PR description rather than in-source.
CodeRabbit review on #1079: 9 lines of comment for one config value. Cut it to the actual claim (20s exceeds the proxy's 15s drain, matches the macOS supervisor's own headroom) and drop the "why not rely on systemd's default" elaboration — that's in the PR description and commit message, not owed to every future reader of this file.

Small, focused fix: adds an explicit TimeoutStopSec=20 to the Linux unit and a regression-pinning test assertion. The rationale comment traces back to both the proxy's 15-second drain and the macOS supervisor's matching 20-second timeout, which is exactly the right level of documentation for a value that was previously "correct by accident."
The test assertion uses "TimeoutStopSec=20 " (with a trailing newline) to avoid accidentally matching a longer value like TimeoutStopSec=200 — a subtle but correct detail.
All checks pass. Ready for human review.

Verified the rationale end to end against source rather than taking the description's word for it: the proxy's 15s deadline (main.go:957), the supervisor's 20s wait before it insists (supervise.go:90), and the exact-value assertion with a trailing \n that correctly rules out a TimeoutStopSec=200 false pass. The parity argument holds and the honest-limit section is accurate — this is string rendering, and #1076 is the right place for real-systemd behavior.
Two notes, neither blocking, both in the inline comment plus one follow-up below.
Follow-up: the same gap is still open on the macOS side. The darwin plist sets no ExitTimeOut, so it relies on launchd's implicit default — which is 20s, exactly equal to the supervisor's own 20s SIGTERM→SIGKILL wait. launchd can SIGKILL the supervisor at the same instant the supervisor decides to escalate, so there is zero designed headroom on the platform this PR cites as its model for headroom. Worth an explicit ExitTimeOut above 20 in the plist, but out of scope here.
Nit on the description, not the code: the 90s default isn't "undocumented" — it's in systemd-user.conf(5). The actual risk is that it's manager-configurable, which is what the test's own wording ("an unasserted value") gets right.

suggestion — explicit over implicit is the right call, but the comment tells only half the story and the direction is worth stating out loud.
The net effect on a stock systemd is a narrower window, not wider. DefaultTimeoutStopSec is 90s in both the system and user managers (systemd-user.conf(5)), so this trades 90s of slack for 20s. That's still the right trade — a manager default is configurable and could just as easily be lowered under 15s, which is the real hazard — but the comment reads as if it's adding headroom when it's mostly pinning it.
And 15s is the drain deadline, not the process's stop time. shutdownCtx bounds the HTTP servers and both pipelines, but costLedger.Close() and sessions.Close() run after that deadline with no context governing them (cmd/authbridge-proxy/main.go:987-995). So the 5s of margin here is covering unbounded post-deadline work — and per the ledger's own comment, that flush is exactly what turns "a restart loses up to 60 seconds of cost" into "an orderly stop loses nothing." A slow disk at that moment is a SIGKILL and a lost open minute.
Either is fine to resolve in a sentence of comment rather than a code change; the value itself is defensible.
Four CodeRabbit findings, all verified against actual code before fixing: - must-fix: the plan doc's Status header, bullet 6, and bullet 7 read as if this branch delivered the TimeoutStopSec fix and the fakeSystemctl/fakeLoginctl harness + goos refactor. It doesn't — confirmed via `git diff main...this-branch`, neither touches cmd_service_platform.go's function signatures nor adds that harness file. Both live on separate, not-yet-merged sibling PRs (#1079, #1080). The doc is shared across three independently-reviewed branches and each copy drifted to claim collective progress as if it were local. Corrected the Status header, bullets 6/7, Cross-cutting themes 1/3, and Suggested next steps 1/2 to attribute that work to the correct PR instead of this one. - The pre-emptive stop() call before t.Cleanup(stop) can never match a real leftover: the unit name embeds this process's own pid, unique per run, so there's nothing with that exact name to have been left behind. It only produces spurious "cleanup:" failure logs on every normal passing run (confirmed from this PR's own prior CI output: systemctl stop exit 5, reset-failed exit 1, seven such lines on a fully green run). Removed; t.Cleanup(stop) alone still covers real end-of-test teardown. - requireRealSystemd's comment claimed mirroring "the same four skip guards" as TestWaitBootedOut_RealLaunchd; it has three, and the darwin test's fourth (launchd refusing to start the test agent at all) has no systemd analog — exactly the asymmetry this file's own header comment already explains. Reworded to match. - The CI step comment attributed all setup-failure catching to ABCTL_SYSTEMD_TESTS=required; that only covers the soft-failure path (session unreachable, so the step warns and the Go test itself Fatalfs). A hard failure (enable-linger itself failing) is instead caught by bash -e failing the step outright, before Test ever runs. Named both paths.

CodeRabbit review: two things the comment got wrong, both about framing rather than the value itself (which the reviewer confirms is fine). - systemd's own DefaultTimeoutStopSec is 90s in both system and user managers, per systemd-user.conf(5). Setting 20 narrows that window down toward the proxy's 15s deadline; it doesn't add headroom on top of an undocumented default, since there was already more than enough margin. The real hazard the explicit value guards against is a future *lower* default, not a shorter one. - 15s bounds the HTTP servers and both pipelines specifically (shutdownCtx in main.go), not the process's total stop time. costLedger.Close() and sessions.Close() run after that deadline with no context governing them — confirmed against origin/main, which has moved since this branch forked and now contains exactly that. The 5s of margin over 15 is covering that unbounded tail, not padding an already-bounded number. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Alan Cha <Alan.cha1@ibm.com>
CodeRabbit review, plus a proactive check for the same doc issue already found on #1076: - callLog built its shell redirection with a bare %s path. If TMPDIR contains whitespace or shell metacharacters, the generated fragment is invalid and the fake fails before it ever records its arguments. Use the existing shQuote helper instead of fmt.Sprintf (which is now unused and removed from imports). - Same root cause as #1076's must-fix: this branch's copy of the plan doc claimed the TimeoutStopSec fix (bullet 7) as landed. It isn't — confirmed via `git diff main...this-branch`, which touches none of cmd_service_platform.go's TimeoutStopSec content. That fix lives on sibling PR #1079, not merged yet. Corrected the Status header, bullet 7, Cross-cutting themes 2/3, and Suggested next steps 1 to attribute it there instead of here. Bullet 6 and Cross-cutting theme 1 (the fakeSystemctl/fakeLoginctl harness) are correctly this branch's own contribution and are left as closed.

…s on #1080 Second round of CodeRabbit findings on #1080, all verified before fixing: - must-fix (x2): bullet 6's header still read "CLOSED (Tier 2) 2026-09-17" even though this PR (#1080) is itself unmerged — a doc announcing its own merge before it happens. Bullet 7's header was already corrected last round, but its body still described TimeoutStopSec as an accomplished, tested fact, which isn't true on this branch. Reworded bullet 6 as "Closing in #1080 (this PR, unmerged)" — true both before and after merge — and bullet 7's body as "In review (#1079)", matching the reviewer's suggested framing exactly. - readCallLog returned nil on ANY read error, not just "file doesn't exist" — so a broken harness (PATH not applied, /bin/sh missing, temp dir gone) would read identically to "genuinely never called", making every negative call-count assertion in this file vacuous. Now distinguishes os.ErrNotExist (real "never called") from any other read error (t.Fatalf, so a harness break is loud). - The linger happy-path tests asserted only the marker file's presence, never the actual loginctl invocation shape. A typo'd verb, the wrong uid, or a bare enable-linger with no argument would each still exit 0 and still write the marker — exactly the wrong-verb bug class this whole harness exists to catch, just not caught here. Added callLog- backed checks on both subtests, plus a new test confirming loadService's happy path calls daemon-reload then enable --now, in that order, with the exact unit name — previously only inferred through failure-path error messages, never checked on a run that succeeds. - Collapsed controlService(goos string, action string, ...) to controlService(goos, action string, ...) per a minor nit; declined the deeper `type goos string` swap-proofing the same comment raised, as it flagged itself as likely out of scope for this PR. 24 subtests now (was 22), all passing.

…g on #1076 Fourth round of CodeRabbit findings, all verified before fixing: - must-fix: bullets 6/7's bodies still said "Fixed:" for work living entirely on #1079/#1080 (both open, unmerged), and theme 1 was struck through as if #1080's half had landed too. Changed both labels to "#1080 (open):" / "#1079 (open):", matching the terse citation style already applied elsewhere; un-struck theme 1 and reworded it to attribute the real-systemd half to this branch and the fake-harness half to #1080 specifically, rather than claiming both landed. - Bullet 6's "Still open" note said Tier 3 (real-systemd integration test) was "still not built" — contradicting bullet 5 immediately above it, which is this branch's own accomplishment. Pointed at bullet 5 instead of repeating the stale claim. - The cleanup t.Logf added two rounds ago still produced noisy "cleanup:" lines on every normal passing run — confirmed from this PR's own CI output (run 35750943568): systemd-run transient units are garbage-collected once inactive, so by teardown time `stop` on an already-gone unit exits 5, and `reset-failed` on one that's neither failed nor loaded exits 1 — both routine, not a leak. Added isExitCode and filter exactly those two known-benign codes, so only a genuinely unexpected cleanup failure gets logged. - Documented an untracked gap surfaced while building this PR: ABCTL_LAUNCHD_TESTS=required is never set by any workflow, so TestWaitBootedOut_RealLaunchd still skips in every CI run — the exact trap this PR exists to avoid on the Linux side, left open on the macOS one. No macOS runner exists here to close it, so noted against #944/#956 in "Relationship to other issues" rather than left to be rediscovered.

The combined plan doc was copied identically across three
independently-reviewed branches and tried to track all three PRs'
live merge status via prose ("CLOSED", "Fixed:", "sibling PR #X
(open)"). That drifted every time any of the three changed, which is
exactly what produced round after round of "must-fix: this claims
work that hasn't landed" review comments.
None of the other docs in authbridge/docs/superpowers/ do this.
Checked all nine: they track status via task checkboxes scoped to one
document/one branch/one eventual PR (main-channel.md's last section
is literally "Task 7: ... and PR", singular), and reference the
parent issue number in the header rather than tracking sibling PRs'
merge state inline. Multi-PR work gets separate documents
(pricing-consolidation-core.md / -phase0.md), not one document
describing several.
Split accordingly:
- specs/2026-09-16-linux-systemd-lifecycle-design.md: the frozen
research (systemd/launchd background, the full gap analysis as
originally found) — timeless, makes no claims about which PR fixes
what, so it can't go stale the way the old doc did.
- plans/2026-09-21-systemd-real-integration-test.md: a small,
self-contained task list for this branch's own work only, no
reference to #1079/#1080's status at all.
Deletes the old combined doc.

- Cite main.go's shutdown timeout by symbol, not line number, in the spec doc — main.go isn't part of this PR's diff and keeps moving as unrelated PRs merge, so any line citation there goes stale under continued review regardless of how carefully it's checked once. - Record #1079's TimeoutStopSec=20 as closing gap 7, now that it has merged; the doc previously described a gap that no longer exists on main. - Clarify the #966 reference: that issue is closed, and its allow-legacy-plugin-tag exemption matches the whole file via strings.Contains, not just the one mention. - Replace exec.Command("kill", ...) with syscall.Kill: requireRealSystemd doesn't guard the kill binary, so a slim image missing it would surface as a failed test (with ABCTL_SYSTEMD_TESTS=required set) rather than the environment-problem skip it actually is. - Tie the crash test to renderUnitFor's actual output: Restart=on-failure was hand-copied into the systemd-run args, so deleting the property from renderUnitFor's linux branch wouldn't have failed this test — it would go on proving a fact about systemd the shipped unit no longer requests. - Narrow the reset-failed cleanup filter to match on message rather than exit code: exit 1 is systemd's generic failure code, so filtering by code alone swallowed nearly everything the call could produce, not just the confirmed-benign "unit doesn't exist" case. - Reword the comment above the 1s negative-assertion window; it described a drain that had already finished by the time stop() returns, not a grace period being given here.

The spec's real-systemd integration-test half and the serviceStatus/serviceControl-accuracy half are untouched here. - fakeLaunchctl now delegates to installStub instead of hand-copying its body without the exec.LookPath reachability check: the vacuous-pass hole installStub closed for fakeSystemctl/fakeLoginctl was still open on the launchd side, in the very file this harness is modelled on. - Document that noSystemctlOnPath replaces PATH rather than prepending to it, so it must never run after fakeSystemctl/fakeLoginctl in the same subtest. - Thread callLog through "daemon-reload failure is reported, enable is never attempted" so the never-called claim is a literal check against the call log, matching every other never-called assertion in this file, rather than something inferred from the error message format.
