- sqlite scheduler tick: a failed COMMIT (or ROLLBACK) left the connection released with a stuck-open transaction, wedging the writer slot forever — the one commit site missing the drop-+-reopen-replenish arm; tick now takes the conn by value with a poisoned disposition (drop + replenish), the commit-fault seam reaches the tick, and failed_tick_commit_replenishes_the_writer_slot pins the arm - pg save_offset_tx stored GREATEST($3,0) where the wave-8 gate's negative-seed fix (raw seed, ADR-023 §2 2026-10-11 annotation) covered only the auto-commit form; mem's merged in-tx read clamped a staged negative seed against a phantom zero; both fixed and the tx-form totality pinned by a new stamped suite leg (in_tx_reads_see_own_writes) green on all three columns vs the live harness server - pg: a failed forwarder register leaked the channel refcount forever (no receiver to drop it) — listen/spawn_bridge now unregister on the register error, mirroring the subscribe-failure arm; register doc corrected to put the failure disposition at the call site - pg forwarder: nine poisoned-mutex expect() panics converted to the mem crate's into_inner recovery idiom (no-expect-outside-tests rule) - core encode_payload: a deeply-nested Value aborted the process in serde_json's unguarded serializer recursion and the fuzz pin blessed storing bytes no decoder could read back; encode now rejects nesting past 127 containers (the empirically-verified decode limit) with typed Codec — decode-aligned boundary pins added to the fuzz invariant and value_type_tests, applied pre-publish within the open class-1 window - scheduler sleep deadlines: Instant + Duration overflow caps (MAX_SLEEP_S, tick-and-resleep) on all three engines for far-future boundaries; sqlite tick claim stamp now saturating_add - docs read true again: Error::Closed scope (stream try_recv arm), validation whitespace wording, sqlite lib.rs phantom durability knobs, pg lock.rs honest autocommit wording, mem tx/stream merge + wake- granularity wording; wakes.rs stale allow(dead_code) removed - tests: value_type_tests exercised its own map_err instead of the function under test (fixed); unwrap_or_default reference encodes panic with cause - docs/reviews/004-pre-release-general-review.md records nine fixed + sixteen parked findings (sqlite seam panic-safety armor, watcher post-death-subscribe hang + initial-stat self-kill, pg forwarder TOCTOU/hang/diagnosability, pg BIGINT server-side stamp overflow, mem growth/outbox notes, pg identifier-truncation doc note, smaller) and two false positives caught on verification; implementation.md review-rounds entry + core-contract backlog rows updated - gates: build, workspace tests (sqlite 194, core 27, suite legs new), full live pg column 127+25+9, clippy -D warnings, fmt, fuzz replay 6/6, wasm32 check, doc gate -D warnings — all green
alkstore-postgres
The Postgres engine of the alkstore
family: the core contract implemented on tokio-postgres +
deadpool-postgres, natively async (no blocking bridge, no
spawn_blocking seam), with a hand-rolled LISTEN forwarder.
let store = alkstore_postgres::open(&dsn, alkstore_postgres::PgOpts::default()).await?;
Engine posture — multi-host native. Connections are per-process
state; nothing assumes a shared host. Connection budget: max_size
pooled connections + 1 non-pooled listener connection per LISTEN-ing
process (pooled connections cannot carry LISTEN) — size the server
for the sum. v1 TLS is effectively unavailable: the engine hardwires
NoTls on every connection path, so network confidentiality must come
from the deployment topology. Queue/stream/lock/schedule tables live
in one engine-owned PostgreSQL schema (default alkstore,
per-engine option).
See the family README for the interface and the deployment matrix, and the Postgres engine spec for the driver's details.
