HTTPd M1 — production serve (m1-serve-production)

Summary

Completes plan todo m1-serve-production: long-lived build/li-httpd with multi-worker fork pool (SO_REUSEPORT), HTTP/1.1 keep-alive, static (argv epoll) and reverse-proxy (.conf epoll loop) — beyond serve_once / routed oracle stubs. Mixed static+proxy on one .conf uses httpd_drain_slot_i in the Li proxy loop for static routes.

Agent continuation

  1. Gate: ./scripts/test-serve-production.sh after ./scripts/build-li-httpd.sh.
  2. Full plan gates: ./scripts/httpd-plan-gates.sh.
  3. Workers: server.workers = 2 in TOML (flatten → workers=2) or LI_HTTPD_WORKERS=auto|N for argv mode.

Changed

Area Paths
Runtime runtime/li_rt_net.c — httpd_fork_workers_i, workers= config, SO_REUSEPORT listen
Package packages/li-net-httpd/src/lib.li — httpd_begin_worker_pool before production loops
Config scripts/flatten-httpd-config.py, examples/serve_production.toml
Gates scripts/test-serve-production.sh, scripts/httpd-plan-gates.sh
Plan docs/superpowers/plans/2026-05-16-li-httpd-plan.md — m1-serve-production: completed

Not changed

  • Tier-5 bench matrix / live Pages (no new CSV).

Follow-up

  • m1-upstream-keepalive completed in docs/release-notes/2026-05-23-httpd-m1-upstream-keepalive.md.

Breaking

N/A.

Security

Production gate uses loopback-only listeners; same path traversal / auth limits as other M1 runtime smokes.
