From 31e8c30c34bbd05c78bc194459d2d03a93e26119 Mon Sep 17 00:00:00 2001 From: "jabber.developer2" Date: Tue, 17 Feb 2026 17:31:50 +0300 Subject: [PATCH 01/34] feat: add flat-file database backend for message history MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add pluggable storage backend abstraction (vtable) to the database layer, allowing selection between SQLite (default) and a new flat-file backend that stores messages as human-readable plain text files. New files: - database_sqlite.c: extracted SQLite backend from database.c - database_flatfile.c: plain text backend with tolerant parser, LMC correction chains, UTF-8/BOM/CRLF handling, integrity checks Commands: - /privacy logging flatfile — switch to flat-file backend - /history verify [] — check integrity of stored history Fixes: - Add missing 'off' guard in flatfile backend - Enable CHLOG/HISTORY prefs when switching to flatfile mode Logs stored in ~/.local/share/profanity/flatlog/{account}/{contact}/{date}.log Format: {ISO8601} [{type}|{enc}|id:{id}|corrects:{id}] {sender}: {message} Updated: CHANGELOG, CONTRIBUTING.md, profrc.example, man page, cmd_defs, Makefile.am, test stubs, functional test support (PROF_FLATFILE=1) --- CHANGELOG | 13 + CONTRIBUTING.md | 14 + Makefile.am | 22 + docs/profanity.1 | 31 +- profrc.example | 7 + src/command/cmd_defs.c | 16 +- src/command/cmd_funcs.c | 57 + src/config/files.h | 1 + src/database.c | 698 ++---------- src/database.h | 40 + src/database_flatfile.c | 1239 ++++++++++++++++++++++ src/database_sqlite.c | 819 ++++++++++++++ tests/functionaltests/proftest.c | 8 +- tests/unittests/database/stub_database.c | 26 + 14 files changed, 2346 insertions(+), 645 deletions(-) create mode 100644 src/database_flatfile.c create mode 100644 src/database_sqlite.c diff --git a/CHANGELOG b/CHANGELOG index 97cfcb5e..a87f345a 100644 --- a/CHANGELOG +++ b/CHANGELOG @@ -1,3 +1,16 @@ +0.16.0 (unreleased) +=================== + +Changes: +- Add flat-file database backend as alternative to SQLite for message history. + Stores messages as human-readable plain text files.

Path traversal via crafted JID (HIGH): _ff_jid_to_dir() now strips '/', '\' -> '_' and collapses '..' -> '__', preventing a malicious federated JID from escaping the log directory. 2. Log injection via unescaped message body (HIGH): Add _ff_escape_message()/_ff_unescape_message() -- escape \n, \r, \\ in message text on write, unescape on read. Prevents remote contacts from injecting fake log lines with forged sender/timestamp/encryption. 3. Metadata field injection (HIGH): Add _ff_escape_meta_value()/_ff_unescape_meta_value() -- escape |, ], \\, \n, \r in stanza_id/archive_id/replace_id. Parser uses escape-aware _ff_find_unescaped_char() and _ff_split_meta() instead of strchr/strsplit. 4. Sender ": " parsing confusion (MEDIUM): Escape ": " -> "\: " in XMPP resource on write. Parser uses _ff_find_unescaped_colonspace() + _ff_unescape_sender_resource(). 5. LMC correction chain cycle -> infinite loop (MEDIUM): Add visited hash-set and FF_MAX_LMC_DEPTH (100) limit to chain walker. 6. Unbounded getline() -> OOM (MEDIUM): Add FF_MAX_LINE_LEN (10 MB) cap in _ff_readline(); overlength lines are skipped with a warning. Replaces all char buf[8192]/fgets() sites with dynamic getline() + truncated-line detection at EOF. 7. Symlink attack + TOCTOU on file creation (MEDIUM): Replace fopen("a") with open(O_WRONLY|O_APPEND|O_CREAT|O_EXCL|O_NOFOLLOW) + fdopen() -- atomic new-file detection, symlink rejection via O_NOFOLLOW. _ff_ensure_dir() checks g_lstat() for symlinks.

Each file uses pipe-delimited records with a sparse byte-offset index that is rebuilt on demand and cached in memory. - Rewrite _ff_write_record / _ff_read_records for single-file format - Add sparse index (every Nth record) for O(log N) seek on history read - Cursor-based pagination: _ff_get_previous_chat uses saved byte offset - LMC corrections applied in-place during read (_ff_apply_lmc) - Newline escaping (\n) in message bodies for line-based storage - Simplify verify: parse + timestamp order + LMC reference check - Update parser helpers for new field layout --- src/database_flatfile.c | 578 ++++++++++++++++++++++++--------- src/database_flatfile.h | 39 ++- src/database_flatfile_parser.c | 9 +- src/database_flatfile_verify.c | 359 +++++++++----------- 4 files changed, 608 insertions(+), 377 deletions(-) diff --git a/src/database_flatfile.c b/src/database_flatfile.c index b78869c9..e8b36316 100644 --- a/src/database_flatfile.c +++ b/src/database_flatfile.c @@ -31,6 +31,8 @@ #include #include +#include +#include #include #include #include @@ -52,6 +54,261 @@ // ========================================================================= char* g_flatfile_account_jid = NULL; +static GHashTable* g_contact_states = NULL; + +// ========================================================================= +// Per-contact state / sparse index +// ========================================================================= + +ff_contact_state_t* +ff_state_new(const char* filepath) +{ + ff_contact_state_t* state = g_malloc0(sizeof(ff_contact_state_t)); + state->filepath = g_strdup(filepath); + state->cursor_offset = -1; + return state; +} + +void +ff_state_free(ff_contact_state_t* state) +{ + if (!state) + return; + g_free(state->filepath); + g_free(state->entries); + g_free(state); +} + +static gboolean +_ff_state_build(ff_contact_state_t* state) +{ + FILE* fp = fopen(state->filepath, "r"); + if (!fp) + return FALSE; + + int c1 = fgetc(fp); + int c2 = fgetc(fp); + int c3 = fgetc(fp); + if (c1 == 0xEF && c2 == 0xBB && c3 == 0xBF) { + state->bom_len = 3; + } else { + state->bom_len = 0; + fseek(fp, 0, SEEK_SET); + } + + state->n_entries = 0; + state->total_lines = 0; + size_t msg_count = 0; + + while (1) { + off_t pos = ftell(fp); + gboolean truncated = FALSE; + char* buf = ff_readline(fp, &truncated); + if (!buf) + break; + if (truncated) { + free(buf); + break; + } + + if (buf[0] == '\0' || buf[0] == '#') { + free(buf); + continue; + } + + state->total_lines++; + + if (msg_count % FF_INDEX_STEP == 0) { + char* space = strchr(buf, ' '); + if (space) { + char* ts_str = g_strndup(buf, space - buf); + GDateTime* dt = g_date_time_new_from_iso8601(ts_str, NULL); + if (dt) { + if (state->n_entries >= state->cap_entries) { + state->cap_entries = state->cap_entries ?

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).

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.

End-to-end migration of 1M rows: ~5 min -> ~1 min. H1 cache g_slist_length(merged) out of the write loop — was O(n²) via 2000 list walks at 500-row progress interval, now O(1). S7a_export_cold @ 1M: 309 s -> 11.2 s (-96 %) L1 splice existing flatfile lines into merged via ownership transfer instead of 12-strdup deep-copy + g_date_time_ref; free list nodes only, NULL out existing. S7b_export_dedup @ 1M: 304 s -> 13.3 s (-96 %) RSS @ S7b 1M: 2.4 GB -> 1.9 GB H2 mkstemp() with random suffix instead of fixed "{log_path}.export.tmp". Eliminates the unlink-and-retry race where two concurrent exports could clobber each other's in-flight tmp files. M4 SHA-256 over full body (incremental g_checksum_update) in the dedup-key fallback. Previous body[:256] hash collided on common preambles (signatures, code blocks) — second occurrence silently dropped on import. M2 Refuse _ff_read_all_lines on files > 2 GB. Each line expands ~10x in heap on parse; without a cap we OOM-kill prof on large flatfiles. Surface a clear error instead. M5 Break the outer import loop on system-level INSERT failure. Was cascading "Import of X failed" through every remaining contact when the real issue was disk-full / sqlite locked. Verified on bench-pipeline-max: 1M rows, full content diff, mismatches=0. baseline.csv updated.
