cfc0695c8a feat(smartacme): Integrate @push.rocks/taskbuffer TaskManager to coordinate ACME certificate issuance with per-domain mutex, global concurrency cap, and account-level rate limiting; refactor issuance flow into a single reusable cert-issuance task, expose issuance events, and update lifecycle to start/stop the TaskManager. Add configuration for concurrent issuances and sliding-window order limits, export taskbuffer types/plugins, and update tests and docs accordingly. 2026-02-15 22:22:12 +00:00

# Changelog
## 2026-02-15 - 9.1.2 - fix(docs)
document built-in concurrency control, rate limiting, and request deduplication in README
- Added a new 'Concurrency Control & Rate Limiting' section to the README describing per-domain mutex, global concurrency cap, and sliding-window account rate limiting (defaults: 1 per domain, 5 global, 250 per 3 hours).
- Documented new SmartAcme options in the interface: maxConcurrentIssuances, maxOrdersPerWindow, and orderWindowMs.
- Added example code showing configuration of the limits and an example of request deduplication behavior (multiple subdomain requests resolving to a single ACME order).
- Added an example subscription to certIssuanceEvents and updated the components table with TaskManager entry.
- Change is documentation-only (README) — no code changes; safe patch release.
## 2026-02-15 - 9.1.1 - fix(deps)
bump @push.rocks/smarttime to ^4.2.3 and @push.rocks/taskbuffer to ^6.1.2
- @push.rocks/smarttime: ^4.1.1 -> ^4.2.3
- @push.rocks/taskbuffer: ^6.1.0 -> ^6.1.2
- Only package.json dependency version updates; no code changes
## 2026-02-15 - 9.1.0 - feat(smartacme)
Integrate @push.rocks/taskbuffer TaskManager to coordinate ACME certificate issuance with per-domain mutex, global concurrency cap, and account-level rate limiting; refactor issuance flow into a single reusable cert-issuance task, expose issuance events, and update lifecycle to start/stop the TaskManager. Add configuration for concurrent issuances and sliding-window order limits, export taskbuffer types/plugins, and update tests and docs accordingly.
- Added dependency @push.rocks/taskbuffer and re-exported ITaskEvent/ITaskMetadata in ts/index.ts; also imported/exported taskbuffer in ts/plugins.ts.
- Replaced interestMap coordination with TaskManager + TaskConstraintGroup(s): 'cert-domain-mutex' (per-domain mutex, resultSharingMode: 'share-latest'), 'acme-global-concurrency' (global concurrency cap), and 'acme-account-rate-limit' (sliding-window rate limiter).
- Introduced a single reusable Task named 'cert-issuance' and moved the ACME issuance flow into performCertificateIssuance(), splitting progress into named steps (prepare/authorize/finalize/store) and using notifyStep() for observable progress.
- Exposed certIssuanceEvents via SmartAcme.certIssuanceEvents and wired TaskManager.start()/stop() into SmartAcme.start()/stop().
- Added new ISmartAcmeOptions: maxConcurrentIssuances, maxOrdersPerWindow, orderWindowMs to control concurrency and rate limiting.
- Updated tests to remove interestMap stubs and adapt to the taskbuffer-based flow; cleaned up client/retry stubbing in tests.
- Updated readme.hints.md with guidance on concurrency, rate limiting, and taskbuffer integration.
## 2026-02-15 - 9.0.1 - fix(acme-http-client)
Destroy keep-alive HTTP agents and DNS client on shutdown to allow process exit; add destroy() on AcmeHttpClient and AcmeClient, wire agents into requests, and call client/smartdns destroy during SmartAcme.stop; documentation clarifications and expanded README (error handling, examples, default retry values).

Usage in `ts/plugins.ts`: `import * as acme from './acme/index.js'` (replaces `acme-client`)
## Concurrency & Rate Limiting (taskbuffer integration)
As of v9.1.0, `@push.rocks/lik.InterestMap` was replaced with `@push.rocks/taskbuffer.TaskManager` for coordinating concurrent certificate requests. This provides:
- **Per-domain mutex** (`cert-domain-mutex`): Only one ACME issuance per TLD at a time, with `resultSharingMode: 'share-latest'` so queued callers get the same result without re-issuing.
- **Global concurrency cap** (`acme-global-concurrency`): Limits total parallel ACME operations (default 5, configurable via `maxConcurrentIssuances`).
- **Account-level rate limiting** (`acme-account-rate-limit`): Sliding-window rate limit (default 250 orders per 3 hours, configurable via `maxOrdersPerWindow`/`orderWindowMs`) to stay under Let's Encrypt limits.
- **Step-based progress**: The cert issuance task uses `notifyStep()` for prepare/authorize/finalize/store phases, observable via `smartAcme.certIssuanceEvents`.
Key implementation details:
- A single reusable `Task` named `cert-issuance` handles all domains via `triggerTaskConstrained()` with different inputs.
- The `shouldExecute` callback on the domain mutex checks the certmanager cache as a safety net.
- `TaskManager.start()` is called in `SmartAcme.start()` and `TaskManager.stop()` in `SmartAcme.stop()`.
- The "no cronjobs specified" log messages during tests come from taskbuffer's internal CronManager polling — harmless noise when no cron tasks are scheduled.
## Dependency Notes
- `acme-client` was replaced with custom implementation in `ts/acme/` + `@peculiar/x509` for CSR generation

It features a built-in RFC 8555-compliant ACME protocol implementation, pluggable challenge handlers (DNS-01, HTTP-01), pluggable certificate storage backends (MongoDB, in-memory, or your own), and structured error handling with smart retry logic.

## 🔀 Concurrency Control & Rate Limiting
When many callers request certificates concurrently (e.g., hundreds of subdomains under the same TLD), SmartAcme automatically handles deduplication, concurrency, and rate limiting using a built-in task manager powered by `@push.rocks/taskbuffer`.
### How It Works
Three constraint layers protect your ACME account:
| Layer | What It Does | Default |
|-------|-------------|---------|
| **Per-domain mutex** | Only one issuance runs per base domain at a time. Concurrent requests for the same domain automatically wait and receive the same certificate result. | 1 concurrent per domain |
| **Global concurrency cap** | Limits total parallel ACME operations across all domains. | 5 concurrent |
| **Account rate limit** | Sliding-window rate limiter that keeps you under Let's Encrypt's 300 orders/3h account limit. | 250 per 3 hours |
### 🛡️ Automatic Request Deduplication
If 100 requests come in for subdomains of `example.com` simultaneously, only **one** ACME issuance runs. All other callers automatically wait and receive the same certificate — no duplicate orders, no wasted rate limit budget.
```typescript
// These all resolve to the same certificate with a single ACME order:
const results = await Promise.all([
smartAcme.getCertificateForDomain('app.example.com'),
smartAcme.getCertificateForDomain('api.example.com'),
smartAcme.getCertificateForDomain('cdn.example.com'),
]);
```
### ⚡ Configuring Limits
```typescript
const smartAcme = new SmartAcme({
accountEmail: 'admin@example.com',
certManager,
environment: 'production',
challengeHandlers: [dnsHandler],
maxConcurrentIssuances: 10, // Allow up to 10 parallel ACME issuances
maxOrdersPerWindow: 200, // Cap at 200 orders per window
orderWindowMs: 2 * 60 * 60_000, // 2-hour sliding window
});
```
### 📊 Observing Issuance Progress
Subscribe to the `certIssuanceEvents` stream to observe certificate issuance progress in real-time:
```typescript
smartAcme.certIssuanceEvents.subscribe((event) => {
switch (event.type) {
case 'started':
console.log(`🔄 Issuance started: ${event.task.name}`);
break;
case 'step':
console.log(`📍 Step: ${event.stepName} (${event.task.currentProgress}%)`);
break;
case 'completed':
console.log(`✅ Issuance completed: ${event.task.name}`);
break;
case 'failed':
console.log(`❌ Issuance failed: ${event.error}`);
break;
}
});
```
Each issuance goes through four steps: **prepare** (10%) → **authorize** (40%) → **finalize** (30%) → **store** (20%).
## Certificate Managers
SmartAcme uses the `ICertManager` interface for pluggable certificate storage.
@@ -314,6 +384,7 @@ Under the hood, SmartAcme uses a fully custom RFC 8555-compliant ACME protocol i
| `AcmeError` | Structured error class with type URN, subproblems, Retry-After, retryability |
| `AcmeOrderManager` | Order lifecycle — create, poll, finalize, download certificate |
| `AcmeChallengeManager` | Key authorization computation and challenge completion |
| `TaskManager` | Constraint-based concurrency control, rate limiting, and request deduplication via `@push.rocks/taskbuffer` |
All cryptographic operations use `node:crypto`. The only external crypto dependency is `@peculiar/x509` for CSR generation.
