# Implementation Spec: Round 16 — COMPLETE
|
||||
|
||||
## Goal
|
||||
Make the round-7-15 abstractions actually usable — a single, runnable, wired
|
||||
example showing high-level primitives composing together.
|
||||
|
||||
## New File
|
||||
|
||||
### examples/high_level.rs (mytheclipse-core)
|
||||
`crates/mytheclipse/examples/high_level.rs`
|
||||
- One realistic flow demoing, wired together:
|
||||
1. RuntimeConfig::auto() — auto thread/core sizing from host CPU
|
||||
2. parallel_map — bounded fan-out + AggregateError
|
||||
3. RetryExt — ergonomic .retry() on a Future
|
||||
4. ShutdownGuard — RAII exactly-once cleanup
|
||||
5. AutoReconnectPool — self-healing resource pool (dead value replaced)
|
||||
6. AutoMetricsServiceBuilder — auto latency/outcome metrics
|
||||
- Run: `cargo run -p mytheclipse --features full --example high_level`
|
||||
|
||||
## Verified Output (real run, 8-core host)
|
||||
```
|
||||
1. RuntimeConfig::auto() -> worker=8, blocking=12, compute=8, io=4
|
||||
2. parallel_map -> [10, 20, 30, 40, 50]
|
||||
3. RetryExt with 4 attempts -> 42
|
||||
4. ShutdownGuard fired 1x (exactly-once, even on unwind)
|
||||
5. AutoReconnectPool first acquire -> 999
|
||||
6. AutoMetrics -> 1 counters, 1 histograms
|
||||
```

# Implementation Spec: Round 17 — Race-Safety Stress Tests + Doctests
|
||||
|
||||
## Goal
|
||||
Misi project: menghilangkan boilerplate race-condition. Bukti nyata bahwa
|
||||
primitives aman di bawah kontensi tinggi. Tambahkan:
|
||||
1. Stress/concurrency tests untuk primitives race-sensitive di core crate
|
||||
2. Doctest `# Examples` untuk fitur round 7-16 agar docs.rs langsung berguna
|
||||
|
||||
## 1. New file: crates/mytheclipse/tests/race_stress.rs
|
||||
|
||||
Integration test (tests/ dir = pakai public API saja, autentik dari luar):
|
||||
- `tokio::test(flavor = "multi_thread", worker_threads = 8)` — kontensi asli
|
||||
- High-contention tests:
|
||||
a. TokenBucket try_consume atomic — 64 tasks × 1000 consumes dari 1 bucket
|
||||
capacity 100, rate tinggi → total consume ≤ capacity per window, no double
|
||||
b. SemaphorePool acquire/release concurrent — 100 tasks acquire+release
|
||||
cycle, final available == capacity, no leak
|
||||
c. AutoReconnectPool — healthy probe retval, 50 concurrent acquire, semua
|
||||
dapat item valid
|
||||
d. RateLimitedQueue concurrent enqueue/dequeue — 8 worker × 1000 item,
|
||||
total dequeue == total enqueue
|
||||
e. ShutdownGuard exactly-once — 10 clones-ish concurrent drops → callback
|
||||
count == 1 (via Arc<AtomicUsize>)
|
||||
f. parallel_map 10k items concurrency 32 — hasil input-ordered, nilai benar
|
||||
g. parallel_for_each 10k items concurrency 32 — side-effect count == 10k
|
||||
h. AggregateError from_results merge 100 results mix ok/err — error count
|
||||
benar, values semua lolos yang ok
|
||||
- Assertions: `assert_eq!` pada counts; harness FAILS kalau race → flaky
|
||||
|
||||
## 2. Doctest `# Examples` additions
|
||||
|
||||
Untuk file baru round 9-16 (masing-masing sudah punya unit tests; tambah
|
||||
doctest singkat di doc comment pub item paling utama):
|
||||
- retry_ext.rs: `RetryExt::retry` contoh 1-liner
|
||||
- auto_metrics_service.rs: AutoMetricsServiceBuilder contoh
|
||||
- runtime_auto.rs: RuntimeConfig::auto contoh
|
||||
- shutdown_guard.rs: ShutdownGuard contoh
|
||||
- aggregate_error.rs: AggregateError::from_results contoh
|
||||
- parallel_map.rs: parallel_map + parallel_for_each contoh
|
||||
- pool.rs AutoReconnectPool: contoh
|
||||
|
||||
Doctest wajib compile: `cargo test --doc --workspace --all-features`
|
||||
|
||||
## Files

- new: crates/mytheclipse/tests/race_stress.rs
|

# Implementation Spec: Round 19 — Criterion Benchmarks
|
||||
|
||||
## Goal
|
||||
Buktikan klaim "secepat mungkin" (tujuan awal project) dengan benchmark
|
||||
nyata. Ukur overhead primitives race-safe vs baseline naif, supaya user
|
||||
tahu trade-off dan bisa memilih fitur dengan data.
|
||||
|
||||
## New files
|
||||
|
||||
### crates/mytheclipse/benches/primitives.rs
|
||||
Criterion bench untuk primitives core (feature `full`):
|
||||
- `parallel_map`: throughput 1000 item, concurrency 8 vs sequential loop
|
||||
(pakai `black_box`)
|
||||
- `retry_ext`: overhead `.retry()` success-first vs 2 retries
|
||||
- `rate_limiter`: `RateLimiter::try_acquire` throughput (atomic CAS)
|
||||
- `semaphore_pool`: acquire/release cycle throughput — bukti no-leak + low
|
||||
overhead
|
||||
- `aggregate_error`: `from_results` 1000 results all-ok vs 50% err
|
||||
- `shutdown_guard`: new + drop cost
|
||||
|
||||
## Dependency
|
||||
- dev-deps: `criterion = "0.5"` + `[[bench]]` harness = false
|
||||
- `harness = false` di Cargo.toml bench section (criterion punya main sendiri)
|
||||
|
||||
## Verification
|
||||
1. `cargo bench -p mytheclipse --bench primitives --all-features` — runs,
|
||||
reports times
|
||||
2. `cargo build --workspace --all-features` — exit 0
|
||||
3. `cargo clippy --workspace --all-features` — 0 new warnings
|
||||
4. Spec + commit + push
|
||||
|
||||
## Notes
|
||||
- Criterion 0.5 mendukung MSRV 1.60 — aman untuk rust-version 1.75.
|
||||
- Bench tidak jalan di CI (hanya manual) — tidak mempengaruhi pipeline.
