feat(bench): synthetic load harness for flat-file backend (P1-P5)
End-to-end performance and correctness harness for the flat-file +
SQLite database backends. Lives in tests/bench/, built only on
demand (`make bench`); not part of `make check`.
Components
gen_history (P1)
Deterministic corpus generator. Knobs: lines, contacts, years,
seed, stanza-id mode (uuid/libpurple/conversations/mixed), LMC
rate, MAM-OOO rate, resources/contact, length profile
(short/mixed/long/extreme). Emits the canonical
flatlog/<account>/<contact>/history.log layout used by
ff_verify_integrity. ~340 LOC.
bench_runner (P1, P2.5)
S1 cold tail-access via sparse index
S2 warm tail-access (page cache hot)
S3 deep pagination (1000 binary-search lookups)
S4 first-time index build (cold file -> ff_state_ensure_fresh)
S5 incremental extend (asserts no full rebuild path)
S6 real ff_verify_integrity over the contact tree
Reports total/err/warn/info issue counts in the CSV note.
bench_long_messages (P2)
L1-L14 long-message stress: 1KB up to 9.9MB bodies, plus
oversized line rejection (10MB+1 -> ff_readline returns ""),
embedded-newline / pipe / emoji body patterns, full parse on
100x1MB, 1000x100KB sustained append.
bench_failure_modes (P3)
F1-F15 failure-injection: truncated last line, mid-file CRLF,
mid-file BOM, LMC cycle, LMC depth>FF_MAX_LMC_DEPTH, manual
': ' in resource, RTL/ZWSP, Latin-1 byte, empty body,
mtime/inode flip, empty file. Each test asserts expected issue
levels and reports PASS/FAIL.
bench_export_import (P5)
Links real database_export.c + database_sqlite.c + database.c
and drives log_database_export_to_flatfile /
log_database_import_from_flatfile under load.
Subcommands: seed, export, import, roundtrip, verify.
S7a/b export, S8a/b import, S8e roundtrip with full byte-by-byte
content diff of every row in (from_jid, to_jid, message,
timestamp, type, stanza_id, archive_id, encryption, replace_id).
Make targets
bench-quick / bench / bench-full
bench-longmsg, bench-failure
bench-multicontact, bench-lmc, bench-ooo
bench-export, bench-import, bench-roundtrip
bench-pipeline, bench-pipeline-max (1M rows)
bench-compare, bench-update-baseline
Volume controls: BENCH_VOLUME (small/medium/max), BENCH_PIPE_ROWS,
BENCH_PIPE_ROWS_MAX, BENCH_DATA_DIR, BENCH_CSV.
Baseline + regression checking (P4)
tests/bench/baseline.csv 51 rows: S1-S6 x {small,lmc,ooo}
+ L1-L14 + F1-F15 (11 of 15) +
S7/S8 x {pipe100k, pipe1M}.
compare_baseline.py median over duplicate rows;
exits 1 on any (scenario, volume)
slowdown >= threshold (default 25%).
Verified at scale
bench-pipeline-max: 1,000,000 rows, full content diff
seed 17 s, export 304 s, import 31 s, idempotent re-import 10 s,
diff 2.7 s -- mismatches=0.
Findings surfaced by the harness
Export scales super-linearly: 4 s @ 100k -> 304 s @ 1M (76x for
10x rows). Cause: g_slist_sort on the merged list + per-row
ProfMessage/ff_parsed_line_t allocations. RSS peaks at 1.4 GB
on 1M. Worth a follow-up.
Export progress reporting only fires during the write phase --
the merge+sort phase (~95% of wall time at 1M) is silent.
/history export and /history import are blocking on the main
UI thread; profanity is frozen for the duration (~5 min @ 1M).
ff_readline sets *truncated=TRUE on partial-write tail but
ff_verify_integrity does not surface this -- partial writes
go unflagged (failure-injection F1).
Parser silently truncates body at first unescaped ': ' if a
resource was manually edited to contain it (F9).
In gen_history (caught by the bench's own real-verify pass):
g_strndup mid-codepoint truncation on UTF-8 bank strings -- fixed.
Linkage strategy
database_flatfile.c + parser + verify + common.c are linked
unconditionally. The export/import bench additionally links
database.c + database_sqlite.c + database_export.c. bench_stubs.c
provides minimal stubs for log_*, prefs_*, connection_get_jid,
jid_create, files_*, message_*, ui hooks. integrity_issue_free
is a weak symbol so it falls back to the real database.c
implementation when that file is linked.

# Flat-file backend bench harness
|
||||
|
||||
Synthetic load tests for the flat-file database backend. Not part of `make
|
||||
check` — must be invoked explicitly. See `REVIEW.txt` Phase-9 plan for the
|
||||
design and scenario list.
|
||||
|
||||
## Quick start
|
||||
|
||||
```sh
|
||||
# small (~40 MB corpus due to mixed length profile, ~10 seconds total)
|
||||
make bench-quick
|
||||
|
||||
# medium (~2 GB corpus, ~1 minute)
|
||||
make bench BENCH_VOLUME=medium
|
||||
|
||||
# max (~20 GB corpus, ~5–10 minutes, requires NVMe + plenty of free disk)
|
||||
make bench BENCH_VOLUME=max
|
||||
|
||||
# Everything: P1 + long messages + failure-injection + S9/S10/S11 variants
|
||||
make bench-full
|
||||
|
||||
# Compare against committed baseline (see Baseline section below)
|
||||
make bench-compare
|
||||
|
||||
# Just the long-message battery (L1–L14, ~5 seconds, self-contained)
|
||||
make bench-longmsg
|
||||
|
||||
# Just failure-injection tests (F1–F15, ~10 ms total)
|
||||
make bench-failure
|
||||
|
||||
# S7/S8 export/import pipeline at default 100k rows
|
||||
make bench-pipeline
|
||||
|
||||
# Same pipeline at 1M rows (~5 min, ~3 GB disk)
|
||||

## Scenarios in P1 (`make bench`)
|
||||
|
||||
| ID | What | Bench function |
|
||||
|---|---|---|
|
||||
| S1 | Cold tail-access (drop cache, fetch last 100 lines via sparse-index seek) | `run_tail_access(drop=1)` |
|
||||
| S2 | Warm tail-access (cache hot) | `run_tail_access(drop=0)` |
|
||||
| S3 | Deep pagination (1 000 binary-search lookups across the index) | `run_deep_pagination` |
|
||||
| S4 | First-time index build (cold file → `ff_state_ensure_fresh`) | `run_first_build` |
|
||||
| S5 | Incremental extend (append N lines, ensure no full rebuild) | `run_incremental_extend` |
|
||||
| S6 | Verify-equivalent full parse pass | `run_verify` |
|
||||
|
||||
## P2 corpus variants (separate make targets)
|
||||
|
||||
Each variant generates its own corpus and reuses `bench_runner`'s scenarios.
|
||||
|
||||
| Target | Corpus | Purpose |
|
||||
|---|---|---|
|
||||
| `make bench-multicontact` | 200 contacts × 5k lines × 3 years | S9 — directory discovery & multi-state cost |
|
||||
| `make bench-lmc` | 100k lines, 30 % LMC corrections | S10 — correction-heavy LMC chain throughput |
|
||||
| `make bench-ooo` | 100k lines, 20 % MAM out-of-order | S11 — verify must surface timestamp warnings |
|
||||
| `make bench-longmsg` | (no corpus, self-contained tests) | L1–L14 — long-message stress |
|
||||
| `make bench-full` | runs all of the above sequentially | reporting baseline |
|
||||
|
||||
## Long-message tests (L1–L14)
|
||||
|
||||
Run via `make bench-longmsg`. Each test generates N messages with a specific
|
||||
body size and content pattern, writes via `ff_write_line`, reads via
|
||||
`ff_readline + ff_parse_line`, asserts body length match, emits a CSV row.
|
||||
|
||||
| ID | Body | Pattern | Count | What it verifies |
|
||||
|----|------|---------|-------|------------------|
|
||||
| L1 | 1 KB | filler | 100 | sanity / fast path |
|
||||
| L2 | 10 KB | filler | 100 | escape pipeline at moderate size |
|
||||
| L3 | 100 KB | filler | 100 | paste-bomb territory |
|
||||
| L4 | 1 MB | filler | 50 | 50 MB pipe — measures throughput |
|
||||
| L5 | 5 MB | filler | 10 | 50 MB pipe |
|
||||
| L6 | 9.9 MB | filler | 4 | just under `FF_MAX_LINE_LEN` (10 MB) |
|
||||
| L7 | 10 MB+1 | filler | 1+1 | **rejection path**: `ff_readline` returns "" + skips |
|
||||
| L8 | 100 KB | embedded `\n` | 50 | escape stress (each `\n` doubles to `\\n`) |
|
||||
| L9 | 100 KB | embedded `\|` | 50 | body pipes (not metadata) shouldn't choke parser |
|
||||
| L10 | 100 KB | UTF-8 emoji | 50 | 4-byte codepoints / `g_utf8_validate` path |
|
||||
| L11 | 1 KB | filler | 100 | sanity baseline (re-run, expect L1-equivalent) |
|
||||
| L12 | mixed | 5 × 1 MB at end | 1000 | pagination memory: last-100 with paste-bombs |
|
||||
| L13 | 1 MB | filler | 100 | full parse pass on 100 MB file |
|
||||
| L14 | 100 KB | filler | 1000 | sustained append throughput |
|
||||
|
||||
L7 specifically asserts `ff_readline` rejects oversized lines (returns `""`,
|
||||
logs "line too long", continues to next line — the very-next-line is a normal
|
||||
record, must parse OK).
|
||||
|
||||
## Export/import pipeline (S7/S8)
|
||||
|
||||
Run via `make bench-pipeline` (default 100k rows) or `make bench-pipeline-max`
|
||||
(1M rows). Each subcommand emits a CSV row; full content diff is enforced
|
||||
on every roundtrip.
|
||||
|
||||
| Target | Sub-scenarios | What |
|
||||
|---|---|---|
|
||||
| `bench-export` | `S7a_export_cold`, `S7b_export_dedup` | Seed SQLite N rows → real `log_database_export_to_flatfile`; second pass measures dedup hot path |
|
||||
| `bench-import` | `S7_seed_export`, `S8a_import_cold`, `S8b_import_idempotent` | Seed → export → wipe DB → real `log_database_import_from_flatfile`; second import asserts dedup (rows added = 0) |
|
||||
| `bench-roundtrip` | `S8e_roundtrip` | Seed DB-A → export to flatfile → import to fresh DB-B → **full byte-by-byte content diff** of every row in (from_jid, to_jid, message, timestamp, type, stanza_id, archive_id, encryption, replace_id) |
|
||||
| `bench-pipeline` | all of the above | combined run |
|
||||
| `bench-pipeline-max` | same, at 1M rows | heavy: ~3 GB disk, ~5 min |
|
||||
|
||||
The bench links the **real** `database_export.c` + `database_sqlite.c` +
|
||||
`database.c` so timings reflect actual production code paths (merge sort,
|
||||
GHashTable dedup, transactional INSERT, etc.).
|
||||
|
||||
`BENCH_PIPE_ROWS` overrides the default row count; `BENCH_PIPE_ROWS_MAX`
|
||||
overrides the max-volume default.
|
||||
|
||||
The roundtrip CSV note records each phase wall-time:
|
||||
`rows=N seed=Xms export=Yms import=Zms diff=Wms exported=… imported=… mismatches=…`.
|
||||
|
||||
The bench also exposes `bench_export_import` directly with five subcommands
|
||||
(`seed`, `export`, `import`, `roundtrip`, `verify`) for ad-hoc use:
|
||||
|
||||
```sh
|
||||
./tests/bench/bench_export_import seed --rows=1000000 --account=foo@bar
|
||||
./tests/bench/bench_export_import export --account=foo@bar --csv=out.csv
|
||||
./tests/bench/bench_export_import roundtrip --rows=100000 --csv=out.csv --full-diff
|
||||
./tests/bench/bench_export_import verify --db-a=A.db --db-b=B.db
|
||||
```
|
||||
|
||||
## Failure-injection (F1–F15)
|
||||
|
||||
Run via `make bench-failure`. Each test crafts a deliberately corrupt log file
|
||||
and asserts how the backend handles it. Exits non-zero on any failure.
|
||||
|
||||
| ID | Injection | Expected behaviour |
|
||||
|---|---|---|
|
||||
| F1 | Last line truncated mid-write + partial appended line | Verify completes; line counted as a parse error or skipped without crash |
|
||||
| F2 | CRLF line endings on three lines mid-corpus | Verify reports CRLF warning |
|
||||
| F3 | UTF-8 BOM bytes appearing mid-file (not at start) | Verify reports unparsable line ERROR for that record |
|
||||
| F7 | LMC cycle: A→B references and B→A references | Verify completes without infinite loop (cycle handled at read-time, not verify) |
|
||||
| F8 | LMC chain depth 200 (over `FF_MAX_LMC_DEPTH=100`) | Verify reports no broken refs (depth-truncation lives at read-time) |
|
||||
| F9 | Unescaped `: ` inside resource (manual edit) | Parser splits at first `: ` — body truncated. Not flagged by verify (known parser quirk; documented) |
|
||||
| F10 | RTL override + zero-width space in resource | Bytes preserved literally, parses fine |
|
||||
| F11 | Latin-1 byte (0xC9) followed by ASCII | Verify reports invalid-UTF-8 ERROR (parse-line has Latin-1 fallback, but verify doesn't apply it — intentional) |
|
||||
| F12 | Empty body line | Parses OK, no error |
|
||||
| F14 | File replaced under us (mtime + inode change) | `ff_state_ensure_fresh` triggers full rebuild; `total_lines` updates |
|
||||
| F15 | Empty file (0 bytes) | Verify reports INFO "empty" |
|
||||
|
||||
Latent gaps surfaced:
|
||||
- **F1**: `ff_readline` sets `*truncated=TRUE` but verify doesn't surface this — partial writes go unflagged.
|
||||
- **F9**: parser silently truncates body at first unescaped `: ` — valid manual edits with embedded `: ` are silently corrupted at read-time.
|
||||
|
||||
## Baseline & regression checking (P4)
|
||||
|
||||
```sh
|
||||
# Capture a fresh CSV
|
||||
make bench-full BENCH_CSV=tests/bench/current.csv
|
||||
|
||||
# Compare against baseline.csv (committed)
|
||||
make bench-compare BENCH_CSV=tests/bench/current.csv
|
||||
|
||||
# Once you've reviewed the numbers and they're healthy, snapshot:
|
||||
make bench-update-baseline BENCH_CSV=tests/bench/current.csv
|
||||
```
|
||||
|
||||
`compare_baseline.py` aggregates by `(scenario, volume)` and uses median across
|
||||
duplicate rows. Regression threshold defaults to ±25 %; override with
|
||||
`BENCH_THRESHOLD=15`. Exit code is 0 on no regressions, 1 if any scenario
|
||||
exceeds the threshold.
|
||||
|
||||
The committed `baseline.csv` was captured on this hardware (Debian-bookworm
|
||||
container, NVMe). It's a reference, not absolute — run `make bench-full` and
|
||||
compare on your own hardware to track regressions over time.
|
||||
|
||||
## Generator (`gen_history`) options
|
||||
|
||||
```
|
||||
--lines=N total lines (default 10000)
|
||||
--contacts=K distinct contact JIDs (default 1)
|
||||
--years=Y year span (default 1)
|
||||
--seed=S RNG seed (default 42)
|
||||
--stanza-id={uuid|libpurple|conversations|mixed}
|
||||
--lmc-rate=PCT 0..50, default 3
|
||||
--mam-ooo-rate=PCT 0..50, default 0
|
||||
--resources-per-contact=R default 3
|
||||
--msg-len-profile={short|mixed|long|extreme}
|
||||
--output=DIR default /tmp/cproof-bench-corpus
|
||||
--quiet
|
||||
```
|
||||
|
||||
Layout produced (matches `files_get_data_path("flatlog")` + `ff_jid_to_dir`,
|
||||
so `ff_verify_integrity` can walk the tree without changes):
|
||||
|
||||
```
|
||||
$BENCH_DATA_DIR/
|
||||
flatlog/
|
||||
bench_at_bench.example/ # ff_jid_to_dir(--account)
|
||||
buddy000_at_bench.example/history.log
|
||||
buddy001_at_bench.example/history.log
|
||||
...
|
||||
manifest.txt
|
||||
```
|
||||
|
||||
## Determinism
|
||||
|
||||
Same `--seed` and same `--lines` etc. → byte-identical corpus. Stanza-ids,
|
||||
timestamps, body content all derive from `xorshift64(seed)`.
|
||||
|
||||
The bench runner does *not* re-generate the corpus — `make bench` runs
|
||||
`gen_history` once into `$BENCH_DATA_DIR`, then runs `bench_runner` on it.
|
||||
Re-runs reuse the corpus unless you `make bench-clean` or change `BENCH_VOLUME`.
|
||||
|
||||
## Tuning
|
||||
|
||||
- `BENCH_DATA_DIR=/path` — override corpus location (default `/tmp/cproof-bench-corpus`)
|
||||
- `BENCH_CSV=/path/out.csv` — override results CSV
|
||||
- `BENCH_LOG=1` — surface the flatfile backend's `log_*` output to stderr
|
||||
- `BENCH_VOLUME=small|medium|max`
|
||||
|
||||
## Known limitations
|
||||
|
||||
- **Tail-access** is simulated by sparse-index lookup + read-forward, not the
|
||||
full `_flatfile_get_previous_chat` (which is unreachable here without
|
||||
pulling in profanity's xmpp/connection layer). This still measures the
|
||||
expensive parts (state build, index seek, line parse, LMC application).
|
||||
- **S6 verify** now calls the real `ff_verify_integrity` and walks the
|
||||
canonical layout. CSV note format: `total=N err=N warn=N info=N`. S11 OOO
|
||||
flags ~17 500 timestamp-out-of-order warnings on the 100k/20% corpus.
|
||||
(Resolved as of P2.5.)
|
||||
- **S7/S8 export/import** wired up in P5 — the bench links real
|
||||
`database_export.c` + `database_sqlite.c` + `database.c` and drives
|
||||
`log_database_export_to_flatfile` / `log_database_import_from_flatfile`
|
||||
end-to-end. See "Export/import pipeline (S7/S8)" above.
|
||||
- No baseline-comparison script yet (P4).
|
||||
- F1–F15 failure injection not yet implemented (P3).
|
||||
|
||||
## Disk-usage warning
|
||||
|
||||
Variant corpora can be large because the default `mixed` length profile
|
||||
includes a small fraction of paste-bomb (5–100 KB) and extreme (100 KB–1 MB)
|
||||
messages. Examples:
|
||||
|
||||
| Target | Lines | On-disk size | Note |
|
||||
|---|---|---|---|
|
||||
| `bench-quick` | 10 000 | ~40 MB | due to ~50 paste-bombs in mixed profile |
|
||||
| `bench BENCH_VOLUME=medium` | 500 000 | ~2 GB | check `df` first |
|
||||
| `bench BENCH_VOLUME=max` | 5 000 000 | ~20 GB | NVMe + plenty of free disk |
|
||||
| `bench-multicontact` | 1 000 000 (200×5k) | ~4 GB | 200 separate files |
|
||||
| `bench-lmc` | 100 000 | ~400 MB | single-file |
|
||||
| `bench-ooo` | 100 000 | ~400 MB | single-file |
|
||||
| `bench-pipeline` | 100 000 | ~80 MB SQLite + ~50 MB flatfile | export/import |
|
||||
| `bench-pipeline-max` | 1 000 000 | ~800 MB SQLite + ~500 MB flatfile + ~800 MB DB-B | heavy |
|
||||
|
||||
Set `BENCH_DATA_DIR` if `/tmp` is too small.
|
||||
|
||||
## Adding new scenarios
|
||||
|
||||
1. Add a `run_*` function in `bench_runner.c`.
|
||||
2. Wire it into `main()` with a `scenario_enabled("Sx")` check.
|
||||
3. Document it in this README + REVIEW.txt Phase 9 plan.
|
||||
4. Run `make bench-full BENCH_CSV=tests/bench/current.csv && make bench-compare`
|
||||
— verify no unexpected regressions surface elsewhere.

* vim: expandtab:ts=4:sts=4:sw=4
|

*
|

* F1–F15 failure-injection tests. Each test crafts a deliberately corrupt
|

* or pathological flat-file and asserts how the backend handles it:
|

*
|
||||
* F1 Truncated last line (crash mid-fwrite simulation)
|
||||
* F2 CRLF line endings mid-corpus
|
||||
* F3 BOM not at start (mid-file)
|

* F7 LMC cycle A→B→A (read path must not loop)
|
||||
* F8 LMC chain longer than FF_MAX_LMC_DEPTH (graceful truncation)
|
||||
* F9 Resource containing literal ": " (parser must reject the bad line)
|
||||
* F10 RTL / zero-width chars in resource (parse OK, preserved literally)
|
||||
* F11 Latin-1 fragment in UTF-8 file (invalid UTF-8 → fallback or ERROR)
|
||||
* F12 Empty body — receipt-only carbon equivalent
|
||||
* F14 mtime/inode flip — file replaced under us, ensure_fresh must rebuild
|
||||
* F15 Empty file (0 bytes) — verify reports INFO and continues
|
||||
*
|
||||
* Each test prints PASS/FAIL with detail and writes a CSV row:
|
||||
* F#, "failure", file_size, line_count, wall_ms, peak_rss_kb, note
|
||||
*
|
||||
* Tests run independently against per-test tmp directories; no shared state.

* bench_runner.c
|

* vim: expandtab:ts=4:sts=4:sw=4
|
||||
*
|
||||
* Bench harness driver for the flat-file backend. Measures the underlying
|
||||
* mechanics (state-build, sparse-index lookup, line throughput, verify).
|
||||
*
|
||||
* Pipeline:
|
||||
* 1. Run gen_history first to populate $BENCH_DATA_DIR/contacts/<jid>/history.log.
|
||||
* 2. ./bench_runner --data=DIR --csv=PATH [--scenarios=S1,S2,...]
|
||||
* 3. Each scenario writes a row to the CSV.
|
||||
*
|
||||
* The harness does NOT invoke gen_history itself — that's the Makefile's
|
||||
* job. This keeps the binary's deps minimal.
|
||||
*
|
||||
* Scenarios (S1–S6 in P1):
|
||||
* S1 cold tail-access open contact, drop cache, fetch last 100 lines
|
||||
* S2 warm tail-access same as S1 but page-cache hot
|
||||
* S3 deep pagination scroll back N=100 pages × 100 lines via index
|
||||
* S4 first index build ff_state_new + ff_state_ensure_fresh on cold file
|
||||
* S5 incremental extend append M lines, ensure_fresh -> measure (no rebuild)
|
||||
* S6 verify integrity ff_verify_integrity over full file

* Only ff_* helpers and ff_state_* / ff_verify_integrity are exercised

* reference these symbols are never reached. The stubs exist purely to
|
||||
* resolve the linker.
|

*
|

* log_* writes to stderr when BENCH_LOG=1 in the environment, otherwise
|
||||
* silent — keeps the harness output clean while still letting us debug.

compare_baseline.py — diff a fresh `current.csv` against a committed

`baseline.csv` and exit non-zero on regressions.
|
||||
|

Aggregation rule: same (scenario, volume) → median wall_ms across rows.
|

A regression is a > THRESHOLD percent slowdown vs. the baseline; speedups
|

of any size are reported but never fail the run.

Exit codes:

0 — no regressions
