From b1d820462a61c7cc41cdf987aec630c854453b5e Mon Sep 17 00:00:00 2001 From: "jabber.developer2" Date: Thu, 30 Apr 2026 15:39:30 +0300 Subject: [PATCH] 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///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. --- .gitignore | 21 + Makefile.am | 239 +++++++++++ tests/bench/README.md | 288 +++++++++++++ tests/bench/baseline.csv | 51 +++ tests/bench/bench_common.c | 132 ++++++ tests/bench/bench_common.h | 53 +++ tests/bench/bench_csv.c | 59 +++ tests/bench/bench_csv.h | 26 ++ tests/bench/bench_export_import.c | 645 ++++++++++++++++++++++++++++++ tests/bench/bench_failure_modes.c | 626 +++++++++++++++++++++++++++++ tests/bench/bench_long_messages.c | 497 +++++++++++++++++++++++ tests/bench/bench_runner.c | 537 +++++++++++++++++++++++++ tests/bench/bench_stubs.c | 339 ++++++++++++++++ tests/bench/compare_baseline.py | 136 +++++++ tests/bench/gen_history.c | 592 +++++++++++++++++++++++++++ 15 files changed, 4241 insertions(+) create mode 100644 tests/bench/README.md create mode 100644 tests/bench/baseline.csv create mode 100644 tests/bench/bench_common.c create mode 100644 tests/bench/bench_common.h create mode 100644 tests/bench/bench_csv.c create mode 100644 tests/bench/bench_csv.h create mode 100644 tests/bench/bench_export_import.c create mode 100644 tests/bench/bench_failure_modes.c create mode 100644 tests/bench/bench_long_messages.c create mode 100644 tests/bench/bench_runner.c create mode 100644 tests/bench/bench_stubs.c create mode 100755 tests/bench/compare_baseline.py create mode 100644 tests/bench/gen_history.c diff --git a/.gitignore b/.gitignore index 0559b357..d3a5ff2b 100644 --- a/.gitignore +++ b/.gitignore @@ -114,3 +114,24 @@ coverage/ *.gcda *.gcov coverage.info + +# Bench harness build artefacts (sources are committed; binaries/CSVs aren't) +tests/bench/gen_history +tests/bench/bench_runner +tests/bench/bench_long_messages +tests/bench/bench_failure_modes +tests/bench/bench_export_import +tests/bench/*.o +tests/bench/.deps/ +tests/bench/current.csv +tests/bench/full.csv +tests/bench/quick.csv +tests/bench/longmsg.csv +tests/bench/fail.csv +tests/bench/multi.csv +tests/bench/lmc.csv +tests/bench/ooo.csv +tests/bench/pipe.csv +tests/bench/pipeline.csv +tests/bench/maxpipeline.csv +tests/bench/imp.csv diff --git a/Makefile.am b/Makefile.am index 73e7bb97..ccdecb81 100644 --- a/Makefile.am +++ b/Makefile.am @@ -372,6 +372,231 @@ endif man1_MANS = $(man1_sources) +# --------------------------------------------------------------------------- +# Bench harness — synthetic database load tests.
