- logging.js: structured JSON logging with request IDs (crypto.randomUUID), sanitizeForLog utility, zero external dependencies - metrics.js: in-memory counters (requests_total, bytes), histograms (request_duration_ms with fixed buckets and percentile calculation), gauges (active_requests, uptime), memory-bounded - server.js: replace all console.log/error with structured logger, instrument proxyRequest() with full metrics, add X-Request-ID header propagation, enhance /health with metrics_summary, add GET /metrics endpoint on port 10000 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Implement per-provider rate limiting for the API proxy sidecar: - rate-limiter.js: Sliding window counter algorithm with 1-second granularity for RPM/bytes and 1-minute granularity for RPH. Per-provider independence, memory-bounded, fail-open on errors. - server.js: Rate limit check before each proxyRequest() call. Returns 429 with Retry-After, X-RateLimit-* headers and JSON body. Rate limit status added to /health endpoint. - CLI flags: --rate-limit-rpm, --rate-limit-rph, --rate-limit-bytes-pm, --no-rate-limit (all require --enable-api-proxy) - TypeScript: RateLimitConfig interface in types.ts, env var passthrough in docker-manager.ts, validation in cli.ts - Test runner: AwfOptions extended with rate limit fields Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add Jest devDependency and test script to api-proxy package.json, and add a CI step in build.yml to run container-level unit tests. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add two integration test files that verify the observability and rate limiting features work end-to-end with actual Docker containers. api-proxy-observability.test.ts: - /metrics endpoint returns valid JSON with counters, histograms, gauges - /health endpoint includes metrics_summary - X-Request-ID header in proxy responses - Metrics increment after API requests - rate_limits appear in /health api-proxy-rate-limit.test.ts: - 429 response when RPM limit exceeded - Retry-After header in 429 response - X-RateLimit-* headers in 429 response - --no-rate-limit flag disables limiting - Custom RPM reflected in /health - Rate limit metrics in /metrics after rejection Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Refactor rate limit validation into a standalone exported function that can be tested independently. Adds 12 unit tests covering defaults, --no-rate-limit, custom values, and validation errors. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add test-integration-suite.yml that runs all 23 non-chroot integration tests in 4 parallel jobs grouped by category: - Domain & Network (7 tests): blocked-domains, dns-servers, empty-domains, wildcard-patterns, ipv6, localhost-access, network-security - Protocol & Security (5 tests): protocol-support, credential-hiding, one-shot-tokens, token-unset, git-operations - Container & Ops (8 tests): container-workdir, docker-warning, environment-variables, error-handling, exit-code-propagation, log-commands, no-docker, volume-mounts - API Proxy (3 tests): api-proxy, api-proxy-observability, api-proxy-rate-limit These tests had no CI pipeline before — only chroot tests ran in CI via test-chroot.yml.

Add tests for git clone, fetch, and push with GITHUB_TOKEN authentication through the AWF proxy. Tests skip gracefully when GITHUB_TOKEN is not available. Push test creates a temporary branch and cleans up after itself. Closes #1045 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

There was a problem hiding this comment.
In the RPM rejection path, resetAt is calculated as nowSec + 60, which does not match the actual retry window boundary implied by retryAfter (e.g., at second 59 this reports a reset 60s in the future even though retryAfter is 1s). This makes X-RateLimit-Reset inaccurate; consider setting resetAt to nowSec + retryAfter (consistent with the bytes/min branch and with getStatus().rpm.reset).

create() uses parseInt(env) || DEFAULT, which will silently accept invalid values (e.g. -5 stays -5, 0 becomes default) and can lead to surprising behavior (negative limits effectively rate-limit all requests). Consider validating the parsed values (must be positive integers) and falling back to defaults only on NaN/invalid, not on 0/negative.

The PR title/description focus on adding an authenticated git push integration test, but this PR also introduces substantial new functionality around API proxy observability/rate limiting (new CLI flags, Docker compose env wiring, unit + integration tests, and CI workflows). The PR description should be updated to reflect this expanded scope (or the changes should be split) so reviewers can assess the full impact appropriately.

These flags are documented as "requires --enable-api-proxy", but currently the only place rate limit options are processed is inside the if (config.enableApiProxy) block. If a user passes --rate-limit-* without --enable-api-proxy, the flags are silently ignored. Consider validating this combination and exiting with an error (similar to how --allow-urls requires --ssl-bump / --allow-host-ports requires --enable-host-access).

The test "should include X-RateLimit headers in responses" currently only asserts result.toSucceed() and then ends without checking for any X-RateLimit headers, so it doesn't validate the behavior described by the test name. Either add assertions (likely by forcing a 429 with a low RPM and checking for the X-RateLimit-* headers) or remove this test in favor of the next one that already validates header presence on 429 responses.

The header comment and getWindowCount doc describe a weighted sliding-window algorithm, but the implementation currently just returns win.total for the last 60 slots (no weighting of the previous window). Either update the docs to match the implementation, or implement the described weighting so the limiter matches its stated behavior.

labelKey() builds the metric key from Object.values(labels), which depends on object insertion order. If call sites construct label objects in different key orders, the same logical label set will produce different metric keys and fragment counters/histograms. Consider generating the label key from a stable key order (e.g., sort keys and join values, or join key=value pairs sorted by key).

The server.js was updated to require('./logging'), require('./metrics'),
and require('./rate-limiter'), but the Dockerfile only copied server.js.
This caused the api-proxy container to crash on startup.

The failing tests used bash -c "${script}" (double quotes), which caused
bash to interpret inner double quotes in the curl commands, garbling the
HTTP headers and JSON data. Switch to bash -c '${script}' (single quotes)
and use escaped double quotes for JSON data, matching the pattern used by
the passing tests.
