From c54c448e582720f21450b586903a0f2982847a4d Mon Sep 17 00:00:00 2001 From: Kun Chen <3233006+kunchenguid@users.noreply.github.com> Date: Wed, 19 Aug 2026 09:15:45 -0700 Subject: [PATCH 1/8] test(procevent): make the process-event suite's detached-runner assertions deterministic (#2617) Three assertions in tests/fm-procevent.test.sh depended on a detached runner having finished work that the command starting it does not wait for. reconcile's replacement runner is started through detach_runner, which only forks: reconcile returns and counts the start before that runner has claimed its source or exec'd its child. Any assertion taken straight after reconcile therefore samples a race. - The publish-before-apply recovery section left its always-ready /bin/echo source registered across the recovery reconcile, so that reconcile launched a competing detached poll (observed: started=1) that then raced every later assertion for the source claim, the next capture sequence, and this home's applied record, and outlived the section holding a live claim. It is now retired before that reconcile - re-announcement is proven from the durable inbox alone and needs no registration - and started=0 is asserted so a competing poll cannot be reintroduced unnoticed. This is the same retire-before-reconcile discipline the self-announcing section already carries; that section acquired it after the identical race made its "not-autohandled: self-src" assertion read "already owned: self-src". - The crashed-leader replacement section snapshotted the replacement's claim file and execution log behind a fixed 0.5s settle window. On a loaded machine that window expires first, which is the CI flake behind "a replacement runner started without recording its own claim" and "reconcile did not start exactly one replacement source". Both effects are now waited for with the suite's bounded wait helpers; the exact one-replacement count is still asserted afterwards, unchanged. - The duplicate-start section slept 0.5s for reconcile's runner to record ownership before asserting that a second start loses to it. It now waits for that claim. Also tighten one assertion that could not fail as written: "autohandled: self-src" is a substring of "not-autohandled: self-src", so the applied path was accepted even when the runner reported the capture left for the handler. Evidence: on the unmodified suite, 128 full runs at 6-8x concurrency produced 6 failing runs, all in the crashed-leader section. On the fixed suite, 216 full runs under the same load produced none. Reverting the self-announcing section's retire-before-reconcile line reproduces "already owned: self-src" on the first iteration, confirming the shared mechanism. --- tests/fm-procevent.test.sh | 36 ++++++++++++++++++++++++++++++++++-- 1 file changed, 34 insertions(+), 2 deletions(-) diff --git a/tests/fm-procevent.test.sh b/tests/fm-procevent.test.sh index f92cc198b54..878f71ac81b 100755 --- a/tests/fm-procevent.test.sh +++ b/tests/fm-procevent.test.sh @@ -87,6 +87,21 @@ wait_for() { # [tries] return 1 } +# [tries]: wait until holds at least lines.

Local delivered-unconfirmed dropped the expectation. A marked request whose submit read-back stayed unconfirmed (verdict=pending) is the same not-a-failure outcome the remote leg reports as delivered, but fm-send discarded the parent's pending-reply record for it, so a request that very likely landed stopped being tracked entirely. The record now stays armed on its unconfirmed-delivery marker: a correlated report still resolves it, and an unanswered one still surfaces through the library's own reconciliation. Exit 3 and the local rule that an unconfirmed answer never closes a decision key are unchanged. Remote replies were nagged for a repost they did not need. A remote mate's report reaches the parent's status log only through the asynchronous mirror in fm-procevent-remote-reply.sh, yet the guard read an absent correlated line as proof the mate never reported - even while the answer was still in flight, which is the common case because the mirror's poll window is comparable to the recovery grace. The mirror now publishes one caught-up watermark from a quiet window, and the guard admits a missing report as evidence only once that watermark passes the turn that should have produced it. A genuinely missed report still gets exactly one repost, and a channel that is behind, unarmed, or broken leaves the request durably open and un-nagged rather than nagging blind; the mirror escalates its own continuity failures as before. Tests: a local unconfirmed secondmate send keeps its expectation armed and resolvable; a mirrored correlated remote reply resolves with no repost; a stale or absent watermark withholds the repost while a fresh one still releases it; a quiet remote window publishes the watermark and retirement clears it. * no-mistakes(review): Distinguish preempted polls from quiet windows * no-mistakes(document): Clarify remote reply channel freshness * no-mistakes(lint): Annotate shared remote preemption exit constant --- bin/fm-pending-reply-lib.sh | 77 +++++++++++++++++++++ bin/fm-procevent-remote-reply.sh | 25 ++++++- bin/fm-remote-delta-read.sh | 6 +- bin/fm-remote-job-lib.sh | 10 +-- bin/fm-remote-job-worker.sh | 2 +- bin/fm-send.sh | 23 ++++--- docs/remote-secondmates.md | 4 +- tests/fm-pending-reply.test.sh | 96 +++++++++++++++++++++++++++ tests/fm-remote-job.test.sh | 3 +- tests/fm-remote-reply.test.sh | 49 ++++++++++++++ tests/fm-send-remote-delivery.test.sh | 29 ++++++++ 11 files changed, 303 insertions(+), 21 deletions(-) diff --git a/bin/fm-pending-reply-lib.sh b/bin/fm-pending-reply-lib.sh index a06cba5f8c5..5453585d0e2 100755 --- a/bin/fm-pending-reply-lib.sh +++ b/bin/fm-pending-reply-lib.sh @@ -19,6 +19,9 @@ # # Record location (parent FM_HOME): # state/pending-replies/ +# One more durable input, owned by bin/fm-procevent-remote-reply.sh and read +# here: state/remote-replies/.caught-up, the remote reply mirror's +# watermark (see the remote reply-channel freshness section below). # Each record is a key=value file owned by this library.

The busy-pane completed-turn bound instead routed it straight into wedge_timer_check, which re-escalated "possible wedge, escalation N" (and, past the threshold, demand-deep-inspection) every FM_STALE_ESCALATE_SECS for as long as the review stayed open. busy_turn_bound_check now owns which absorber takes a crossed bound: a crew whose own last status line declares an external wait or a verified captain-held transfer takes the bounded FM_PAUSE_RESURFACE_SECS recheck, and everything else keeps the unchanged wedge timer. The discriminator is the declaration together with liveness (the caller has already confirmed the pane is busy), never a blanket silencing - a crew that declared nothing, or whose pane is not live, escalates exactly as before, and a declared pause still re-surfaces once per long cadence so a forgotten wait cannot rot invisibly. Away mode is untouched: the daemon owns pause triage there and already reads the same vocabulary. The two call sites also no longer clear pause bookkeeping in the same poll the pause cadence recorded it, which would have erased the re-surface throttle and turned the long cadence back into a per-poll re-surface. Tests: a three-phase regression fixture pins the absorbed pause, its long-cadence recheck, and the restored wedge escalation once the declaration is lifted on the same busy over-age pane. Also de-flakes tests/fm-watch-triage.test.sh, which failed spuriously on a loaded machine: fixed liveness budgets were reaping watchers mid-startup, so assertions on post-poll state passed vacuously or failed spuriously. Waits that describe a poll's outcome now wait for a completed poll cycle via the liveness beacon, the heartbeat test waits for the heartbeat it asserts on, and every wait_for_exit budget is the uniform 10s already used elsewhere in the file. * no-mistakes(review): Fail poll-cycle waits on timeout * no-mistakes(review): Prevent poll timeout test hangs * no-mistakes(document): Clarify paused busy-pane supervision --- bin/fm-watch.sh | 74 ++++++--- docs/architecture.md | 2 + docs/configuration.md | 4 +- tests/fm-watch-triage.test.sh | 272 +++++++++++++++++++++++++++------- 4 files changed, 278 insertions(+), 74 deletions(-) diff --git a/bin/fm-watch.sh b/bin/fm-watch.sh index 3f4a57afd65..a3f78fcc335 100755 --- a/bin/fm-watch.sh +++ b/bin/fm-watch.sh @@ -34,12 +34,14 @@ # (window_is_busy true) is exempt from the above, but # only up to BUSY_TURN_MAX_SECS with no completed turn # (state/.turn-ended, or the spawn record before any -# turn completes); past that bound busy_turn_over_age -# routes it through the same wedge timer, so it surfaces -# with the identical "stale: ..." reason, escalation -# count, and demand-deep-inspection marker, for human -# inspection only - never an automatic interrupt, -# signal, or restart of the worker or its tool process. +# turn completes).
