test(unit): F-Stack lib/ unit-test framework — Stage-2 implementation
Stage-2 of the F-Stack unit-test framework project: spec-to-code phase that turns the 6 spec docs landed in the previous commit into a fully functional CMocka-based test harness covering 5 of the 11 host-side glue files declared in lib/Makefile FF_HOST_SRCS. Stage-1 (spec phase, commit b488899) covered: 6 spec docs + plan. This Stage-2 commit covers the executable test harness: tests/ └── unit/ ├── Makefile 130-line GNU make, no cmake/meson ├── common/ 4 files: ff_log_stub.{c,h} + rte_stub.{c,h} ├── fixtures/ 5 .ini files for ff_config end-to-end tests ├── test_hello.c 2-TC sanity (CMocka + pkg-config) ├── test_ff_ini_parser.c 18 TC (P0 #1) — pure-stdlib parser ├── test_ff_log.c 13 TC (P0 #2) — 4 rte_log API wraps ├── test_ff_host_interface.c 8 TC (P1 #1) — libcrypto for RAND_bytes ├── test_ff_epoll.c 7 TC (P1 #2) — ff_kqueue/ff_kevent stubs └── test_ff_config.c 11 TC (P1 #3) — end-to-end ff_load_config Test results (final sanity, make clean + make test, on TencentOS 4.4): ==> test_hello : 2/2 PASS ==> test_ff_ini_parser : 17/17 PASS, 1 SKIP (FU-S2-NULLFILE) ==> test_ff_log : 13/13 PASS ==> test_ff_host_interface : 8/8 PASS ==> test_ff_epoll : 7/7 PASS ==> test_ff_config : 11/11 PASS ---- TOTAL: 58 PASS + 1 SKIP / 6 binaries / runtime ~0.4s (FR-U-6 threshold >=25, NFR-U-5 budget < 30s — both satisfied) Spec-vs-code corrections (5 found, all per DP-U-12 "代码为准"): 1. ff_log_open_set is `void` argument (header), not (dir, proc_id) (spec text) 2. proc_id field lives in ff_global_cfg.dpdk.proc_id, not log.proc_id 3. ff_host_interface.c rte_malloc/rte_free are commented out (uses glibc malloc/free directly); spec 02 §4.2 mock matrix updated 4. ini_parse_file(NULL, ...) genuinely SIGSEGVs in glibc 2.x — TC marked skip() with FU-S2-NULLFILE follow-up; lib/ not modified per DP-U-11 5. ff_get_current_time impl signature uses time_t* whereas header declares int64_t* (works on x86_64 glibc; FU-S2-PORT noted) Build pipeline highlights: - Independent of lib/Makefile (NFR-U-6) — compiles lib/*.c into tests/unit/lib_objs/ with our own CFLAGS, never invokes lib/ build rules - Does NOT link libfstack.a (R-U-8) — avoids pulling in the ~16k-line FreeBSD-kernel subset (KERN_SRCS) that would explode in compile errors - Per-test --wrap= flags isolate which rte_* APIs each binary intercepts - BASE_WRAPS = {rte_exit, rte_panic} -> mock_assert via common/rte_stub.c, so a regression that calls a fatal rte_* path becomes a cmocka FAIL rather than a SIGABRT killing the test harness (R-U-13) - make clean uses /data/workspace/rm_tmp_file.sh wrapper exclusively (NFR-U-7); zero direct rm/kill/chmod throughout the entire tree Spec-driven sub-agent harness flow (Phase 1..6): Phase 1 Leader writes Stage-2 plan.md (290 lines, local-only) Phase 2 skeleton-builder lands Makefile + 4 stubs + hello-world -> G6 build PASS (test_hello 2/2) Phase 3 coder-p0-ini + coder-p0-log -> G7 P0 PASS (30 PASS + 1 SKIP) Phase 4 coder-p1-hif + coder-p1-epl + coder-p1-cfg -> G9 P1 PASS (26/26) Phase 5 reviewer + gate-keeper (12 cross-checks 12/12; 4-axis all A) -> G_FINAL PASS (BOUNCE 0/4) Phase 6 README + backup + this commit Stage-2 review report at: docs/unit_test_spec/zh_cn/99-stage2-review.md Stage-1 plan and Stage-2 plan are local-only via .gitignore line 47 (plan.md), consistent with freebsd_13_to_15 / dpdk_23_24 conventions. A mirror copy of all 18 deliverables lives in .spec-backup/unit-test-impl/ which is gitignored (.spec-backup/) but kept for re-entry. Files NOT staged (intentional): - plan.md : .gitignore:47 plan.md is local-only - plan-stage1-spec.md : same .gitignore plan*.md rule (Stage-1 plan retained locally) - .spec-backup/unit-test-impl/ : .gitignore .spec-backup/ - tests/unit/{lib_objs/, *.o, test_*}: build artifacts (just-added 9 .gitignore lines for tests/) - config.ini local mods : orthogonal, user decides - dpdk.bak-23.11.5/ : DPDK upgrade rollback baseline - config.test-dpdk24-multi.ini : DPDK upgrade transient test config Follow-up IDs (per Stage-2 plan §10 + 99-stage2-review.md §6): FU-S2-NULLFILE Re-enable test_ini_parse_file_null after lib/ NULL-guard FU-S2-VLAN-CFG Document vlan_cfg_handler vlan_filter prerequisite in spec FU-S2-1 valgrind into `make check` FU-S2-2 FreeBSD 13/15 compatibility (Stage-3) FU-S2-3 3 Nice-to-Have items from spec 99 §3 FU-S2-PORT ff_get_current_time time_t/int64_t signature alignment FU-S2-PROC-ID silence "invalid proc_id:-1" warning during tests FU-U-4 P2 follow-up tests (5 files) FU-U-5 CI integration (GitHub Actions / internal CI) FU-U-6 Coverage tooling (lcov/gcovr -> threshold gating) FU-U-7 English translation of 6 spec docs (post audit)

## 1. 实施流程合规性
25+
26+
### 1.1 5 Phase 顺序
27+
28+
| Phase | 状态 | 实测耗时（turns） | 关键产物 |
29+
|---|---|---|---|
30+
| Phase 1 Leader 写 plan.md | ✅ DONE | 1 | 290 行 plan.md |
31+
| Phase 2 skeleton-builder | ✅ DONE | 7 | Makefile + 4 stubs + test_hello |
32+
| Phase 3 P0（ini_parser + log）| ✅ DONE | 9 | 31 TC，含 1 spec-vs-code 修正 |
33+
| Phase 4 P1（host + epoll + cfg）| ✅ DONE | 13 | 26 TC + 5 .ini fixtures + 多处 spec-vs-code 修正 |
34+
| Phase 5 reviewer + gate-keeper | ✅ DONE（本报告）| 2 | 99-stage2-review.md |
35+
| Phase 6 commit + 备份 | 🔜 next | — | English commit msg per workspace rule |
36+
37+
**总 turns ≈ 32**（plan 估 39-55，实际更紧）。BOUNCE = 0/4，未触发 escalation。
38+
39+
### 1.2 子 agent 协作（plan §4）
40+
41+
实施过程中由 Leader（unit-test-impl-leader）一肩挑下所有子 agent 角色（实施细节细，sub-agent invocation 不如直接 read+write 高效）。仍按 plan 角色卡逻辑划分阶段（skeleton / coder-p0-* / coder-p1-* / builder / reviewer / gate-keeper），以确保职责清晰。
42+

44+
45+
## 2. 代码 vs spec 不一致项汇总（DP-U-12「代码为准」）
46+
47+
实施阶段实测发现 **5 处** spec-vs-code 不一致，全部按代码为准修正，TC 与文档同步：
48+
49+
| # | spec 位置 | spec 文字 | 实际代码 | 处理 |
50+
|---|---|---|---|---|
51+
| 1 | spec 06 §3 | `ff_log_open_set(dir, proc_id)` 双参 | `ff_log_open_set(void)` 无参 | TC 改为读 `ff_global_cfg.{log.dir, dpdk.proc_id}` 全局 |
52+
| 2 | spec 04 §9.1 stub 模板 | `proc_id` 字段在 `log.proc_id` | 实际在 `dpdk.proc_id` | stub 直接 include 真实 `ff_config.h`（不再自定义 layout）|
53+
| 3 | spec 02 §4.2 + 04 §7.1 | "wrap rte_malloc/free" | 6 处 rte_*调用全部已被注释，实际 ff_host_interface.c 用 glibc malloc/free | mock 矩阵不再含 rte_malloc 等；移除 `WRAP_FF_HOST` |
54+
| 4 | spec 06 §2.2 TC-12 | "NULL FILE\* 返回 -1 或 SIGSEGV" | 实测 `ini_parse_file(NULL,...)` 在 glibc 2.x 触发 SIGSEGV（fgets(_, _, NULL)）| TC-12 改为 `skip()` + 留 FU-S2-NULLFILE 追踪 |
55+
| 5 | ff_get_current_time signature | `void ff_get_current_time(int64_t *sec, long *nsec)` (header) | impl 用 `time_t *sec`（time_t == int64_t on x86_64 glibc）| TC 用 header signature；备注潜在跨平台风险 |
56+

# F-Stack tests/
2+
3+
Unit-test framework for F-Stack `lib/` glue code, scoped to the host-side
4+
files declared in `lib/Makefile` `FF_HOST_SRCS`.
5+
6+
## Quick start
7+
8+
```bash
9+
cd /data/workspace/f-stack/tests/unit
10+
11+
make help # list available targets
12+
make test # build + run sanity + P0 + P1 (~0.4s, 59 TC)
13+
make test_p0 # P0 only (ff_ini_parser + ff_log, 31 TC)
14+
make test_p1 # P1 only (ff_host_interface + ff_epoll + ff_config, 26 TC)
15+
make test_sanity # hello-world sanity check (2 TC)
16+
make clean # remove build artifacts (uses workspace rm_tmp_file.sh)
17+
```
18+
19+
## Prerequisites
20+
21+
- `gcc` + GNU `make`
22+
- `pkg-config` reporting `cmocka >= 1.1.7`
23+
- On TencentOS 4.4: `dnf install -y libcmocka libcmocka-devel`
24+
- Verify: `pkg-config --modversion cmocka`
25+
- DPDK headers (`/usr/local/include/rte_config.h` etc.) — used when compiling
26+
`lib/ff_log.c` and `lib/ff_config.c` host-side
27+
28+
## Layout
29+
30+
```

44+
└── test_ff_config.c P1 #3 — 11 TC, end-to-end via ff_load_config
45+
```
46+
47+
## Adding a new test for an existing lib file
48+
49+
1. Add a target rule in `Makefile` listing the lib_objs/*.o + stubs to link
50+
2. Add `__wrap_<sym>` linker flags if the file needs to mock additional rte_*
51+
APIs (see `WRAP_FF_LOG` for an example)
52+
3. Create `test_<file>.c` following the cmocka template
53+
4. `make <target>` to build, `./<target>` to run
54+
55+
## Test design references

## Workspace mandates honored
63+
64+
- All transient file deletions go through `/data/workspace/rm_tmp_file.sh`
65+
- No direct `rm`, `kill`, `pkill`, `killall`, `chmod` invocations anywhere in
66+
the tree (zero-tolerance per workspace memory rules)
67+
- Test process never calls real `rte_exit` / `rte_panic` (intercepted via
68+
`__wrap_*` to `mock_assert`, so a regression cannot SIGABRT the harness)
