clawbot	34ebf1abb9	Take in an admin's edits of the state files while running (closes #68) ... smallwebwaf watches SWWAF_STATE_DIR with fsnotify and takes in a saved edit of a state file in place of what it held. It tells its own writes from an admin's by the SHA-256 of what it last read or wrote; each write first takes in an edit made since. An edit that does not parse is renamed to <name>.bad at the file's next write. Every ban on a netblock is checked, and the next ban is worked out from the one that ended last. Two metrics count the edits taken in and set aside. README.md says how to add and lift a ban. Judgement call: a broken edit is set aside at the next write, since an editor's file can be read half written. Model: opus-5-5	2026-10-06 09:48:06 +00:00
clawbot	234c5eac60	Serve Prometheus metrics behind SWWAF_METRICS_TOKEN (closes #23) ... GET /_smallwebwaf/metrics answers in the Prometheus text format for a request carrying SWWAF_METRICS_TOKEN, 401 without it and 404 while it is unset. Every request under /_smallwebwaf/ but the health check now goes through the checks and is answered where it would be forwarded, 404 for any path but the metrics, so none reaches the app. In the client's history a 401 counts as refused, the metrics and the 404s as neither. SWWAF_METRICS_TOP_N bounds the series by country, the rest counted as other. Deviation: go.mod and go.sum written by hand, as go runs only through make. Deviation: no metrics yet for state files read again after an edit or edits set aside; that work is not merged. Model: opus-5-5	2026-10-06 11:40:27 +02:00
clawbot	f51459fbfe	Per-client request rate limits over a minute, an hour and a day (closes #43) ... Each client, one IPv4 address or one IPv6 /64, is counted in two buckets per window, the earlier weighted by how much of it the window covers; at most 20,000 clients are kept, least recently seen dropped first. A request over SWWAF_RATE_LIMIT_PER_MINUTE, _HOUR or _DAY (1000, 10000, 50000, or off) gets 429 before reaching the app. Refused requests count, 413s included. A clock set back over a second behind a bucket's start restarts that window. The log line gains limit_hit and the action rate_limited. Deviation from SPEC.md, per the issue: the 20,000 bound and /64 are fixed. Judgement call: golang-lru/v2 holds the table; httprate does not count refused requests. Deviation: go.mod and go.sum hand-written; no make target tidies them. Model: opus-5-5	2026-10-04 04:24:34 +02:00
clawbot	d76715b0df	Pass-through proxy with timeouts, size limits and a request log (closes #13) ... Milestone 1, the repo's first code. smallwebwaf passes each request to the app and the answer back unchanged, streaming bodies and WebSocket upgrades, within four timeouts (client and app, request and response) and two size limits, and writes one JSON line per request to stdout. Every setting has an SWWAF_ name and a default, and an invalid value stops the start. The repo gets the standard layout: script/ entrypoints, make targets that call them, a Dockerfile that runs the checks, and the Gitea workflow. Disclosure: SPEC.md changed. Go's server reads the request line and headers before smallwebwaf sees the request, so slow headers are closed without an answer, and neither slow nor oversized headers get a log line. Disclosure: standard library only. Model: opus-5-5	2026-10-03 17:24:34 +02:00
