DEV_GUIDE.md and the three READMEs still advertise Go 1.25.7 and
golangci-lint v2.7, but CI has since moved on:
- backend/go.mod declares go 1.26.5, and backend-ci.yml / release.yml /
security-scan.yml all resolve the toolchain via
`go-version-file: backend/go.mod` and then hard-assert
`go version | grep -q 'go1.26.5'`.
- backend-ci.yml pins golangci-lint to v2.9.
So a contributor following DEV_GUIDE.md installs a linter two minor
versions behind CI (different findings locally vs. in CI) and expects a
Go version that the workflow's own assertion step rejects.
Update all ten stale references, and note in the CI section which files
the Go version assertion lives in so future bumps don't miss one.
Docs only, no code or workflow changes.
PR #5423 relaxed the email suffix whitelist: once a whitelist is
configured, non-whitelisted registrable domains are each allowed to
register one account. That behavior activated unconditionally.
Add registration_email_domain_quota_enabled (default false) to gate it:
- Off (default): restore pre-#5423 strict whitelist semantics — with a
non-empty whitelist, non-whitelisted domains are rejected with
EMAIL_SUFFIX_NOT_ALLOWED; the register/verify views restore the
client-side whitelist pre-check and allowed-domain hint.
- On: keep #5423 behavior — one account per non-whitelisted registrable
domain (EMAIL_DOMAIN_REGISTRATION_LIMIT).
- Empty whitelist keeps allowing all domains in both states.
Gating lives in validateRegistrationEmailQuota and (as a race-safety
backstop) createUserWithRegistrationEmailGuard; the repository-level
domain lock + in-tx recheck is unchanged. The admin update field is
*bool (omitted = keep current) so stale full-payload saves cannot
silently flip the switch. Email binding and OAuth auto-signup keep
their strict policy, and pending-OAuth bind-login for existing
accounts is unaffected because the handler resolves existing emails
before the quota check.
Frontend adds the toggle to admin settings (zh/en copy; whitelist hint
restored to strict wording, quota wording moved to the new toggle) and
exposes the flag via public settings + SSR injection payload.
Tests: #5423 quota tests now enable the switch explicitly; new
default-off regression tests cover register/send-code/async/pending
OAuth/OIDC create-account plus both register views; API contract JSON
and the injection drift guard are updated.
Resolves three conflicts, all of the "both branches appended to the same
block" shape. Every one is resolved as a union of both sides; nothing from
either parent is dropped.
- handler/admin/setting_handler_update.go: keep ChannelMonitorHideThroughput
(V2) alongside GrokDefaultTextModel / GrokCrossClientModelMapEnabled /
GrokDefaultBaseURLMode (#5408). UpdateSettings writes every key on each
save, so dropping either side would reset those settings to zero values.
- service/domain_constants.go: keep SettingKeyChannelMonitorHideThroughput
and the three SettingKeyGrok* constants.
- repository/migrations_runner.go: keep the 195 checksum rule (V2) and the
218/219/220 rules (#5408).
Treat cacheTTL=0 as non-expiring known entries, always store negative
refresh markers, and update sticky getSchedulableAccount tests to expect
first-hit fail-open then block after background stats warm.
Keepalive is gated on downstream idle, not upstream tick cadence. The old
fixture wrote progress events every 250ms and could finish without a true
1s idle window on loaded CI runners, so ":\n\n" never appeared. Pause after
preamble long enough for the keepalive ticker before completing the stream.
Fix golangci unused/gofmt on the gentle-backfill path. Plot matrix and
line-chart X axes on the selected [requested_start, requested_end)
window (empty slots while backfill lags), and let plain mouse-wheel zoom
narrow the visible interval so pulse blocks grow wider.
H1/H2: bill search and voice with code defaults when group prices are
nil (explicit 0 remains free); bump API key auth snapshot to v19 and
refresh incomplete media/search/audio projections.
M1–M6: free-quota soft gate fails open on cache miss with background
refresh and 60s default TTL; correct password_auth config docs; default
cross-client model map to true (→ grok-4.5); audit /tts and /web_search;
exclude composite from migration 220 video-price clears; never let a
search surcharge mask token pricing failures.
A Responses stream that ends with response.completed but carries no output,
no usage and no error (only response.created + response.completed observed)
is a silent upstream refusal. It was previously treated as a successful
turn, recording 0 input / 0 output tokens without triggering failover, so
clients saw an empty reply and usage was never billed.
Detect the empty terminal event in both the standard and passthrough
streaming paths while nothing has been written to the client, and return an
UpstreamFailoverError so the next account is tried; when failover is
exhausted the client gets an explicit Responses-format error instead of an
empty success. Streams with any semantic output, usage or error are
untouched. Fixes#5009.
OpenAI upstream requires reasoning input item ids to begin with 'rs' and
rejects replayed item_* ids with 400 ("Expected an ID that begins with
'rs'."). shouldStripOpenAIResponsesInputItemID handled message (msg) and
tool call (fc) ids but not reasoning items, so long Codex sessions restored
through the OpenAI API key passthrough path failed with a converted 502.
Strip non-rs reasoning ids while preserving valid rs_* ids, mirroring the
existing message/tool-call handling. Fixes#5410.
Default channel_monitor_mode to v1 (opt-in V2) so upgrades keep active
probes; existing explicit v2 rows are left alone via ON CONFLICT DO NOTHING
plus migration checksum compatibility for already-applied 195.
V2 first-enable backfill no longer compresses ticks to 5s or uses 24h
chunks. Each tick does recent overlap plus at most one historical chunk
with depth-based ceilings (2h/4h/6h), adaptive grow/shrink, and failure
backoff. Error request_id dedup is bounded by a 90-minute lookback so
ops_error_logs is not scanned for full history.
Also align hide_throughput parse default with privacy-preserving public
runtime (missing key → true).
Check Close/CloseNow errors, drop unused helpers and dead constants,
lowercase ST1005 error strings, and stop discarding unwrap status as an
unused assignment so CI golangci-lint passes.
