clawbot cd04ec0b35 Alerts to Slack and ntfy, each destination with its own queue (closes #90)
check / check (push) Waiting to run
Each alert is posted as a message to the Slack incoming webhook
SWWAF_ALERT_SLACK_WEBHOOK_URL names, and published to the ntfy topic
SWWAF_ALERT_NTFY_URL names, with SWWAF_ALERT_NTFY_TOKEN as a bearer
token and a priority and tag by event. The cooldown and the hourly
limit stay shared; past them, each destination has its own bounded
queue and backoff, and its own sent, failed and dropped counts.
alerts.json keeps the alerts waiting by destination; one whose waiting
is still a list stops the start, saying what to change. A control
character in the ntfy token, or in the instance name ntfy is sent,
stops the start.

Judgement call: messages also give the detail's file, source, error and mode.
Judgement call: alerts_suppressed_total is the same for every destination.

clawbot 432097ee3f Alerts to a JSON webhook, with a cooldown and an hourly summary (closes #26)
check / check (push) Waiting to run
SWWAF_ALERT_WEBHOOK_URL gets one JSON POST per alert, in SPEC.md's
schema, with SWWAF_ALERT_WEBHOOK_HEADERS: ban and permanent_ban, with
the ban's notes, in observe mode too, marked mode observe and worked
out only when the alert would be sent; source_failure for GeoJS;
file_error for a rule or state file with an error. SWWAF_ALERT_EVENTS
chooses; SWWAF_ALERT_COOLDOWN holds back repeats by netblock, file or
source; past SWWAF_ALERT_MAX_PER_HOUR the hour ends in one summary. A
bounded queue, retried with backoff, holds up no request; a 4xx other
than 408 and 429 gives the alert up. alerts.json keeps the queue, the
cooldowns and the hour. Nothing shows the URL's path or query.

Judgement call: the summary's event is summary, which SPEC.md omits.
Judgement call: an admin's ban raises no alert.

clawbot e77dfb6891 Rule files, and bans for a clear sign of attack (closes #24)
check / check (push) Successful in 3m29s
Every *.rules file in SWWAF_RULES_DIR not named with a leading dot is
read at start, and again 2 seconds after the directory's last change.
Each request is checked against the rules after the rate limits: log
notes a match, block refuses with 403, ban refuses and bans the netblock
for SWWAF_ATTACK_BAN_DURATION, made permanent by its next request or
attack. path, query and uri are matched as the request line sent them;
header:Host and header:Transfer-Encoding are refused. Bans gain a cause.
The image ships 00-default.rules.

Judgement call: a header sent twice is matched with its values joined
by ", ".
Judgement call: SWWAF_MAX_BAN_DURATION does not cap a ban for an attack.
Not in this unit: offences for rule matches, with the error burst.
