From cb6bab577f74a83ba391cde575f785aa2c6f2322 Mon Sep 17 00:00:00 2001 From: openclaw-bot Date: Tue, 16 Jun 2026 18:31:00 +0000 Subject: [PATCH 01/12] =?UTF-8?q?test(#1724):=20RED=20=E2=80=94=20chunked?= =?UTF-8?q?=20tx=5Flast=5Fseen=20backfill=20behavior=20+=20edges?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the failing test suite for the new chunkedTxLastSeenBackfill helper that will replace the single-statement #1690 backfill in the next commit. Tests pin the contract reviewers flagged on the prior attempt: - Reader yields between batches (concurrent reader latency bounded — a single-tx fake would NOT satisfy this). - With seedN=12000 + batchSize=5000, progress callback fires >=3 times. - ctx cancel mid-loop -> context.Canceled + partial commits visible. - Concurrent INSERT of new last_seen=0 rows does not trap the loop (maxID snapshot bounds the scan). - Orphan transmissions (no observations) are skipped via EXISTS so the loop terminates deterministically. - Param validation: batchSize<=0 and negative yieldDelay are rejected (no <0 sentinel). - Error propagation: closed DB surfaces -> migration cannot silently report success. Includes a minimal stub of chunkedTxLastSeenBackfill (returns zero/nil) so the file compiles and the tests run to their assertions. The GREEN commit replaces the stub with the real chunked implementation. --- cmd/ingestor/tx_last_seen_backfill.go | 31 ++ cmd/ingestor/tx_last_seen_backfill_test.go | 322 +++++++++++++++++++++ 2 files changed, 353 insertions(+) create mode 100644 cmd/ingestor/tx_last_seen_backfill.go create mode 100644 cmd/ingestor/tx_last_seen_backfill_test.go diff --git a/cmd/ingestor/tx_last_seen_backfill.go b/cmd/ingestor/tx_last_seen_backfill.go new file mode 100644 index 00000000..5d5a383e --- /dev/null +++ b/cmd/ingestor/tx_last_seen_backfill.go @@ -0,0 +1,31 @@ +// Package main: chunked tx_last_seen_v1 backfill (issue #1724). +// +// Stub for the RED test commit — returns zero counts and nil error so the +// test compiles + runs to assertions (which then fail, proving the gate). +// The GREEN commit replaces this body with the real chunked implementation. + +package main + +import ( + "context" + "database/sql" + "time" +) + +type txBackfillProgressFn func(processed, total int64) + +func chunkedTxLastSeenBackfill( + ctx context.Context, + db *sql.DB, + batchSize int, + yieldDelay time.Duration, + progress txBackfillProgressFn, +) (processed int64, total int64, err error) { + // Intentional no-op stub: real implementation lands in the GREEN commit. + _ = ctx + _ = db + _ = batchSize + _ = yieldDelay + _ = progress + return 0, 0, nil +} diff --git a/cmd/ingestor/tx_last_seen_backfill_test.go b/cmd/ingestor/tx_last_seen_backfill_test.go new file mode 100644 index 00000000..b0cf21b3 --- /dev/null +++ b/cmd/ingestor/tx_last_seen_backfill_test.go @@ -0,0 +1,322 @@ +// Tests for the chunked tx_last_seen backfill (issue #1724). +// +// These tests pin the contract the operator-scale fix MUST honor: +// +// - The loop actually yields the writer between batches (concurrent +// reader gets through in bounded latency — NOT just "chunks happen", +// which a single-tx fake could satisfy). +// - With seedN=12000 + batchSize=5000 the progress callback fires +// multiple times (≥3 including terminal) — proves chunking happened. +// - ctx cancellation mid-loop returns context.Canceled, partial rows +// are committed (visible in the DB), no panic. +// - Concurrent INSERT of new last_seen=0 rows during the loop does +// NOT cause infinite iteration (maxID snapshot bounds the scan). +// - Errors from inner queries (RowsAffected via driver poisoning) and +// parameter validation propagate — migration does not silently mark done. +// - Orphan transmissions (no matching observations) do NOT trap the +// loop in an infinite n=0/n=0 ping-pong: the EXISTS filter skips them. + +package main + +import ( + "context" + "database/sql" + "fmt" + "sync/atomic" + "testing" + "time" +) + +// seedTransmissions inserts n transmissions each with one observation, +// last_seen=0.

Symptom (pre-fix, operator scale ~71K tx / 1.5M obs / 2GB DB): - backgroundLoadComplete=true fires. - The async migration starts the single full-table UPDATE under SetMaxOpenConns(1), holds the writer for 10-15 minutes. - Every /api/healthz, /api/packets, /api/stats request queues behind sqlite_busy_timeout. UI appears frozen long after warm-up clears. Fix (this commit): - cmd/ingestor/tx_last_seen_backfill.go (new): chunkedTxLastSeenBackfill snapshots MAX(id), counts eligible rows (last_seen=0 AND has observations AND id<=maxID), then loops bounded UPDATEs (batchSize=5000) with time.NewTimer-based sleeps (no Timer leak via time.After) between batches (yieldDelay=100ms). EXISTS gate skips orphan transmissions so the loop terminates. maxID snapshot keeps concurrent INSERTs out of scope (those are handled inline by stmtBumpTxLastSeen on the writer fast path). Ctx cancellation between batches returns context.Canceled with partial counts; partial commits are visible (migration does NOT flip to done). All errors propagate (snapshot, count, UPDATE, RowsAffected) — the migration cannot silently mark itself done. Progress callback fires per non-empty batch + once terminal with final stable counts; never on a stale n=0 batch. - cmd/ingestor/db.go: wire the helper into the tx_last_seen_backfill_v1 async migration, explicit batchSize=5000, yieldDelay=100ms. Math reality-check: ~71K tx / 5000 ≈ 15 batches × (~50ms exec + 100ms yield) ≈ ~2.5s wall time with readers slotted in at most every 150ms. PR #1725's description claimed ~300 batches × 150ms ≈ 45s — that confused observations (1.5M) with transmissions (71K); real number is ~20x smaller. Indexes idx_tx_last_seen (transmissions(last_seen)) and idx_observations_transmission_id already exist (see internal/dbschema and cmd/ingestor/db.go base schema) — no additional index work required at this commit. Tests: cmd/ingestor/tx_last_seen_backfill_test.go (added in prior commit) pin all the contract points reviewers flagged on PR #1725. Cancel-mid-loop test timing widened from 30ms to 250ms to give the real chunked impl room to commit a batch before the cancel fires; assertion semantics unchanged (partial commits + context.Canceled + no full completion). --- cmd/ingestor/db.go | 34 +++-- cmd/ingestor/tx_last_seen_backfill.go | 161 +++++++++++++++++++-- cmd/ingestor/tx_last_seen_backfill_test.go | 6 +- 3 files changed, 173 insertions(+), 28 deletions(-) diff --git a/cmd/ingestor/db.go b/cmd/ingestor/db.go index a5d54fa0..e5a1a05a 100644 --- a/cmd/ingestor/db.go +++ b/cmd/ingestor/db.go @@ -158,27 +158,29 @@ func OpenStoreWithInterval(dbPath string, sampleIntervalSec int) (*Store, error) } } - // #1690: backfill transmissions.last_seen from MAX(observations.timestamp) - // per transmission.

Schema changes (additive on legacy DBs): - _async_migrations.rows_processed (INTEGER NOT NULL DEFAULT 0) - _async_migrations.rows_total (INTEGER NOT NULL DEFAULT 0) - _async_migrations.last_update_at (TEXT) ensureAsyncMigrationProgressColumns runs ADD COLUMN per column and ONLY swallows the SQLite "duplicate column" error — every other ALTER failure propagates so a real schema problem doesn't get hidden. The CREATE TABLE body carries the same columns for fresh installs. recordAsyncMigrationProgress rate-limits writes to <=1/sec per migration name via a per-name time.Time cache; the rate limit is intentionally NOT a sync.Map so the bookkeeping table doesn't see a write per backfill batch (which on a SetMaxOpenConns(1) DB would compete with the migration's own UPDATE for the writer lock). recordAsyncMigrationProgressTerminal forces a write past the limiter — used to pin final stable counts on both success and failure paths so observers see the final point at which the migration stopped, not stale intermediate data. Retry path (RunAsyncMigration on an existing pending_async or failed row) resets rows_processed / rows_total / last_update_at to zero AND clears the in-memory rate-limit cache, so the next run starts with an honest denominator and no suppressed first write. A single sync.Once guards the warn log for the legacy "progress columns missing" path so a misconfigured DB doesn't generate one log line per batch. db.go wires both the periodic and terminal progress writes into the tx_last_seen_backfill_v1 migration. Failures still propagate to the RunAsyncMigration goroutine (status flips to 'failed' with the error message); the terminal write captures the partial counts at the failure point. --- cmd/ingestor/async_migration.go | 27 +++- cmd/ingestor/async_migration_progress.go | 116 ++++++++++++++++ cmd/ingestor/async_migration_progress_test.go | 125 ++++++++++++++++++ cmd/ingestor/db.go | 10 +- 4 files changed, 270 insertions(+), 8 deletions(-) create mode 100644 cmd/ingestor/async_migration_progress.go create mode 100644 cmd/ingestor/async_migration_progress_test.go diff --git a/cmd/ingestor/async_migration.go b/cmd/ingestor/async_migration.go index 32133db4..644deff0 100644 --- a/cmd/ingestor/async_migration.go +++ b/cmd/ingestor/async_migration.go @@ -41,11 +41,14 @@ import ( func ensureAsyncMigrationsTable(db *sql.DB) error { _, err := db.Exec(` CREATE TABLE IF NOT EXISTS _async_migrations ( - name TEXT PRIMARY KEY, - status TEXT NOT NULL, -- pending_async | done | failed - started_at TEXT NOT NULL DEFAULT (datetime('now')), - ended_at TEXT, - error TEXT + name TEXT PRIMARY KEY, + status TEXT NOT NULL, -- pending_async | done | failed + started_at TEXT NOT NULL DEFAULT (datetime('now')), + ended_at TEXT, + error TEXT, + rows_processed INTEGER NOT NULL DEFAULT 0, + rows_total INTEGER NOT NULL DEFAULT 0, + last_update_at TEXT ) `) return err @@ -68,6 +71,9 @@ func (s *Store) RunAsyncMigration(ctx context.Context, name string, fn func(cont if err := ensureAsyncMigrationsTable(s.db); err != nil { return fmt.Errorf("ensure _async_migrations: %w", err) } + if err := ensureAsyncMigrationProgressColumns(s.db); err != nil { + return fmt.Errorf("ensure _async_migrations progress columns: %w", err) + } var existing string row := s.db.QueryRow(`SELECT status FROM _async_migrations WHERE name = ?`, name) @@ -76,13 +82,20 @@ func (s *Store) RunAsyncMigration(ctx context.Context, name string, fn func(cont if existing == "done" { return nil // already complete, nothing to do } - // pending_async or failed → reset and retry. + // pending_async or failed → reset and retry.

Tightened to: - sample BASELINE reader latency BEFORE backfill starts (avg of 5 probes) - sample BEST reader latency during backfill - assert bestDuring < 80ms absolute AND ratio < 5x baseline (with 5ms floor to avoid sub-ms flakiness) A single-tx implementation that holds the writer the entire wall time would push the during-latency ratio into the 50-100x range and fail deterministically.

charset=UTF-8 Content-Transfer-Encoding: 8bit Group B from PR #1735 round-1 review (must-fix #2). Previously a failed async migration pinned the banner forever: isSteadyState returned false as long as any migration was in 'failed' status, with no path to clear. Operators lost trust in the banner; real new failures got lost in the noise. Fix: - FAILED_AUTO_DISMISS_MS = 10 min from endedAt — past that window the failed entry auto-clears from the banner. The failure is still visible via /api/perf/async-migrations and /api/healthz; only the banner stops blocking. - Per-line × button: explicit user ack immediately removes the failure from the banner. - Fail closed: if endedAt is missing or unparseable, the failure does NOT auto-dismiss (operator must see it). - isSteadyState gets an optional nowMs param (defaults to Date.now) for testability and to make the auto-dismiss math re-render-deterministic.
