clawbot	6ec52e5b87	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 knows its own writes 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 next write. Each edit taken in or set aside is logged and counted. Every ban on a netblock is checked, and the next ban is worked out from the one that ended last. 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 14:18:13 +02:00
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	df2c5042d2	Keep the bans, the clients and GeoJS's answers in state files (closes #17) ... smallwebwaf now copies its state to bans.json, clients.json and lookups.json in SWWAF_STATE_DIR, as "Persistent state" in SPEC.md describes, and reads them back at start, so a restart lifts no ban and gives no client a fresh allowance. Each client gains a history, and a ban's notes count the netblock's requests. bans.json is written SWWAF_STATE_WRITE_DELAY after a ban, and every file every SWWAF_STATE_COUNTER_INTERVAL and at the stop. A ban read back is masked to its netblock and refuses every client in it. A file that does not parse, an unknown version, an entry without a field it needs, or an unwritable directory stops the start. Deviation: no AS number or name, and no ban cause, reason or lifting yet. Model: opus-5-5	2026-10-06 08:31:52 +02:00
