Make short-lived TRACE sessions complete and correlatable without adding a persistent trace channel or changing the existing file-log safety boundary.
Protect ordinary console, subscriber, and file logs from authentication material while preserving the one documented first-start credential notice. Keep action breadcrumbs useful through bounded summaries and a narrow diagnostic name for the emoji-like pagination offset.
Lock the contract with regressions for byte-complete rendering, lazy execution, request-context reuse, credential redaction, unredacted TRACE data, and non-persistence of TRACE records.
Debugging from user-supplied logs was impossible: a successful action left
one terse, over-summarized debug line and nothing about what it sent QQ or
what QQ returned. Add full-chain tracing that stays off disk so it scales to
hundreds of groups.
common:
- New `trace` level (below debug). Never written to file — it lives only in
an in-memory ring + the WebUI stream, so the high-volume full chain costs no
disk. `emit` early-returns for trace before format/render (and before any
lazy producer) when trace isn't active → ~free at the default level.
- Dedicated O(1) circular ring for trace (default 5000, SNOWLUMA_TRACE_BUFFER),
separate from the normal 1000-entry buffer (also switched off array .shift);
getRecentLogs merges both by id.
- request-context.ts: AsyncLocalStorage request id. The logger auto-stamps
`[req#N]` on every line in a request's async chain — across packages, zero
signature threading — and records it on the entry.
- log-summary.renderParamsVerbose: deep render of params (nested structure,
per-string cap, total budget, token/password/secret redaction).
chokepoints (auto-cover every action without touching 100+ handlers):
- onebot api-handler: wrap each action in a request id (only when trace is
live); trace the full params on entry and status+elapsed on exit; the terse
debug breadcrumb still persists to file, failures still warn.
- core bridge.sendRawPacket: trace on success (cmd, sizes, elapsed); warn on
errorCode!=0 / no response (cmd, code, message) so disk keeps real problems.
- protocol highway: fold the bare console.log lines into the logger (trace).
webui: trace as the lowest filterable level; render the `[req#N]` tag and let
search match it. Server needs no change — LOG_LEVELS, getRecentLogs and the
SSE stream carry it through.
