Round 2 of the E22 review, on what round 1 changed.
`redact_query` decodes a parameter before the text rules see it, which is what lets `%40` be
recognised as an address — but `_SECRET_PARAM_RE` was written for the raw, encoded form, where a
value holds no space, `&` or quote. On decoded text its value class stops at the first one, so
`?state=a%20b` kept its tail and `?code=%20abc` was not matched at all. The parameter-NAME rule now
decides, on the key, before any text rule runs.
`forget_user` dropped the account's level elevation without recomputing the root level, so a process
whose only elevated account had just deleted itself kept building TRACE records to throw away, until
some later request happened to recompute it. Every other path that drops an elevation recomputes.
The sink's writer took the erasure lock and THEN waited for a pooled connection, while every request
path already holds a connection when it reaches that lock — so under pool pressure the writer held a
process-global lock against the very requests that could hand a connection back. Same order on both
sides now; the lock still spans the check, the insert and the commit.
The storage-budget notice said the rest of the hour was not kept, and then smaller batches kept
landing underneath it: the window slides and a refused batch is not charged to it. Says what it does.
Tests: the route's half of the erasure rule had no test — only the sink's did — and a source-level
contract test now covers the third insert nobody has written yet. `logs._erased` is process-global
with an hour's memory while the DB fixture hands serial ids back out from 1, so it is swept before
each test like the rate limiters are.
Deep-review round 1 of E22.
- A NUL character (`GET /assets/%00` logs the decoded path) made Postgres
refuse the row and with it the sink's whole batch, every user's rows
included. `to_row` replaces NUL in every text column and in attrs.
- An erased account's lines kept arriving after purge_user's DELETE: the
erasing request's own access line, a queued row, a background task.
`logs.forget_user` runs first; later rows are stored without the account,
and the check and the insert share a lock with the erasure.
- An admin setting the whole process to TRACE logged every user's query
string. The query is now logged only under the user's own Teljes consent,
and decoded before redaction, so `%40` no longer hides an address.
- The browser log ingest has an hourly storage budget per account (5 MiB,
one notice when spent) and reads only a JSON Content-Type, so a
same-site text/plain form post cannot write into a user's log.
RateLimiter takes a per-attempt cost for the byte budget.
- The root level is applied under the elevation lock: two concurrent
changes could leave it at the base while an elevation was active.
- Tests for the running sink (level gate, drain on stop) and for the
admin log level applied at runtime and at boot.
A user can raise their diagnostics level to Részletes (DEBUG) or Teljes (TRACE) for 24 hours from a
new Settings tab, after a consent box that says what is recorded, that the server keeps it and for
how long (the instance's own retention), and that it lapses. Alap is the base and needs no consent.
- users.diagnostics_level/_until (migration 0087), written only by PUT /api/me/diagnostics, which
computes the expiry itself; the demo account cannot raise it. /api/me reports the level in force.
- The server logs an elevated user's requests at that level and stores every line of them
(logs.LevelGate on the stdout handler and the sink; the root is lowered only while an elevation
is active). Teljes adds the redacted query string to the request line.
- POST /api/diagnostics/events stores the browser's log as source=web rows: account from the
session, body capped while streaming, events/attrs capped, re-redacted, events under the
consented level dropped, timestamps clamped, 30 batches a minute, 409 once the level lapsed.
- lib/diagnostics.ts applies the level to the tab and streams only what happens after consent, in
batches, never its own request lines, with a keepalive flush on pagehide; stops on lapse (its
own timer), on withdrawal and on 409.
- Detail hooks at DEBUG: which control was clicked (test id, icon, app copy in English — never user
text, input values or a link's query), visibility/bfcache/resize, filter changes
(lib/filterLog.ts; typed search only at TRACE), player events (lib/mediaLog.ts; media errors are
warnings at every level). Offline/online at the base level.
- "Saját napló" viewer: live, newest first, level groups with counts, search, row details, copy
the filtered events as JSON lines, clear.
- Privacy policy and Terms exist in Hungarian and English (a contract test holds both languages to
the same sections); the policy now describes the server logs and diagnostic logging, self-service
deletion and password sign-in.
Fixed on the way:
- A sync auth dependency ran logs.set_user on a copied context, so the account never reached a
handler's own log lines (measured); a per-request mutable scope carries it now.
- The Settings tab rail left a phone no room (clipped labels, buttons over text): below `sm` it is
a scrolling row above the content.
- PUT /api/me/preferences took a bare dict body; it is a Pydantic model now.
