Agent posts an empty beacon over a tcp4-forced connection every
5 minutes (plus once at startup); panel files the observed source
as SeenIPv4 only when it is a public IPv4 literal, never touching
the reported telemetry address, so 1:1 NAT nodes stop falling back
to their private address in share links.
Agent display version now comes from the agent line's own source
(config.agentDisplayVersion injection + defaultAgentDisplayVersion
constant, currently A2.3.0) instead of being derived from the panel's
displayVersion. Masters resolve the agent line's latest from each
release's agent-version.txt marker (selfupdate.ResolveLatestAgentTarget,
legacy tag derivation as fallback for pre-marker releases): update
intents target the marker under the panel tag, panel-only releases
produce no intent, and the nodes page badges agent rows against
their own line via PanelUpdateInfo.displayLatestAgentVersion.
Windows agent frozen at A2.2.1: release discipline in docs/release.md
+ scripts/release-build.sh (agent assets reused verbatim when the
agent code is unchanged, marker always emitted, no Windows exe),
install-agent.ps1 pinned at V2.4.0, and the A2.2.1 protocol shapes
locked by TestAgentLegacyWindows221Contract.
Agent update tests now derive their targets from the live agent
line instead of a hardcoded A2.0.x the line has passed.
country/country_auto in buildProbeNodeView now come from a local
MMDB lookup of the node's public address (held v4, held v6, seen
v4, seen v6) instead of the pin alone / a hardcoded empty string.
Layered data: local file in the data folder wins, embedded factory
snapshot is the fallback, no database means the pre-flag empty
shape. A weekly job conditionally downloads a fresher copy,
validates it, atomically replaces the local file and hot-swaps the
reader; no URL configured (geoipCountryDefaultURL / the
geoip_country_url setting) means the updater stays silent. No
address ever leaves the master.
XUI_URL default switches from x-ui-linux-<arch> (panel binary) to
x-ui-agent-linux-<arch>; RELEASE_BASE mechanism unchanged. The new
asset exists from the first split release on — bumping RELEASE_BASE
stays a release-step action.
New entry cmd/xui-agent links only the agent dependency closure
(internal/agent + config/logger/selfupdate/xray/util leaves), a
drop-in replacement for the dual-mode binary's agent subcommand:
same invocation (xui-agent agent -config ...), same agent.json and
state files, same wire protocol.
selfupdate gains AgentAssetName (x-ui-agent-linux-<arch>); the
agent's one-click update now downloads the agent asset instead of
the panel binary. Pre-split agents keep fetching the panel asset —
the two forms are interchangeable at the install path.
Probe-only is governed solely by the master-side flag so unchecking it
in the panel takes effect on its own; an agent.json preset would pin
it via the dual-source OR gate. The install-agent.sh/ps1 --probe-only
flag stays for manual installs. tsc --noEmit clean.
buildProbeNodeView now sources its 'name' from probeDisplayName:
the node's public remark (probe_meta.public_remark) when non-empty
after trimming, else the node name as before. Contract field name
unchanged, theme packages untouched, both audiences (anonymous and
admin frames share the builder); the panel's internal node list is
a different surface and keeps the plain node name.
Tests: display-name unit cases (remark / empty / whitespace) and
view-level assertions for both audiences; the public contract
test's seeded expectation updated to the remark (its fixture sets
public_remark='shown publicly' on node 'PubNode').
Unit unification: GB entries converted at 1e9 while every byte
formatter is binary (1024^3), so a 3000 GB limit rendered 2.73 TB
instead of 2.93 TB. calBytes and the form's limit conversion now
use 1024^3. Stored traffic_limits (bytes, typed x1e9) are rescaled
x1.073741824 exactly once at store open, guarded by the
probe_setting mark gb_1024_migrated_v1; calibration values are
stored in GB (no rescale — only their conversion changed) and
price/sort/reset-day are unitless.
One-shot calibration: the form's cal fields are deltas to apply
now. probe.MergeCalDelta folds a non-zero submitted value into the
stored standing correction and keeps the standing value on a
zero/absent submission; putMeta merges against the stored row
(SaveMeta/UpsertMeta keep plain replace — the notify sweep relies
on it). GET no longer echoes the standing correction into the form,
and the frontend keeps the cal inputs as local state that starts
empty and clears on successful save, so a later unrelated save
resubmits nothing.
Tests: calBytes(3000)=3000x2^30; migration 3.0e12 -> 3000x2^30 with
no second rescale on reopen; one-shot flow (save delta, save
unrelated with zero cal -> calibrated traffic unmoved, second delta
accumulates once). Existing TestTrafficCalibrationAppliedAndFloored
expectation updated to the binary figure. No vitest covers
ProbeMetaSection (disclosed in the report).
The item-23 template wrote respawn_period=0 assuming it meant 'no
window' like respawn_max=0; supervise-daemon validates the value at
service start and refuses: Invalid respawn-period value '0'
(Alpine real-machine report). Template now writes 1800, the value
the machine's other supervise-daemon services use; with
respawn_max=0 (unlimited) the period is only the counting window.
Why existing Alpine nodes (Leg-US) never hit it: the respawn lines
exist only since 27a5097 (2026-10-22, item 23) — before that the
template used command_background with no respawn parameters at all,
and panel one-click agent updates swap only the binary, never
regenerate /etc/init.d/x-ui-agent. Only fresh installs (or script
reruns) on OpenRC with the post-item-23 template were exposed.
detect_init_system gains a procd tier ([ -f /etc/rc.common ] &&
command -v procd, after systemd/OpenRC; XUI_INIT_SYSTEM=procd also
accepted). start_via_procd writes /etc/init.d/xui-agent byte-equal
to the unit hand-verified on AX6600 (paths via AGENT_BIN/CONF_DIR),
stops any previous instance before overwriting, enables + starts,
and verifies the process is alive (pgrep, ps fallback). The nohup
fallback now errors out immediately and clearly when nohup itself
is missing (BusyBox-trimmed systems) instead of pretending to start
and failing at the end.
displayUpdateFields returned avail=false whenever the running
build's display version could not be compared (the VV2.1.0
double-letter builds), so the panel swallowed a real update prompt
and the native updater refused to run. displayUpdateFieldsFor now
takes the current display/raw versions as inputs and, when the
display comparison cannot judge, compares the latest tag against
the raw base version with the same tolerant display parser —
unparseable raw base yields false. (Not isNewerVersion: on this
fork's uppercase-V tags it degrades to string inequality, which
would phantom-report an update on form difference alone.)
Parseable display versions keep the segment rule untouched.
Regression tests cover the VV scenario in both raw forms.
NodeService.Probe now checks for a bound agent first: agent-managed
nodes synthesize the result from agent_nodes.last_seen (MAX over
bound agents, ms) — fresh within the same 180s window the heartbeat
job expires by = online with the heartbeat age as latency; stale or
never-seen = offline with LatencyMs -1. No dial, and LastError is
never written for agent nodes (the stored dial error from the
placeholder address https://agent:2053 is also healed on next ⚡,
since the synthesized patch carries an empty error through
UpdateHeartbeat). Traditional-node dial path unchanged; verdict is a
pure function with unit tests.
Frontend: the ⚡ tooltip/menu used t('pages.nodes.probe'), which
since the probe-metadata work resolves to the status-page SECTION
object, so i18next fell back to rendering the raw key. The existing
pages.nodes.testConnection key (present in all 13 locales) is the
right label — point the three usages at it. No new i18n keys.
LazyProc.Call must-finds and panics on a missing export; the trimmed
Tianyi cloud-PC image has no FreeMibIfTable2 in iphlpapi.dll, which
killed the agent on its first collection after a successful register.
Optional procs (GetSystemTimes/GlobalMemoryStatusEx/GetIfTable2Ex+
FreeMibIfTable2 as one gated pair) now resolve through sourceGate
(Find once, missing = source disabled with one warning); the iface
pair is gated together so a missing free proc never leaks the
system table. collectMetrics additionally runs every source through
guardedCall so any residual panic zeroes that source alone.
Pure gate/guard logic lives in probe_guard.go (no build tag) with
Linux-runnable regression tests.
Scope B (Windows agent):
- probe.go split into shared core + probe_linux.go (verbatim Linux
sampler, build-tagged) + probe_windows.go (Win32 sampler: GetSystemTimes
CPU diff, GlobalMemoryStatusEx, fixed-drive df totals, GetIfTable2
counted set, MachineGuid boot identity, registry facts; load and
TCP/UDP counts stay zero - x/sys v0.47.0 exports no wrapper)
- update intents are acknowledged and skipped on Windows (the release
assets are Linux binaries; Windows nodes update via install-agent.ps1)
- cmd/xui-agent-windows: SCM service host (svc.Run + mgr install/
uninstall/start/stop) mirroring main.go's agent lifecycle wiring
- install-agent.ps1: downloads the exe, writes probeOnly agent.json,
registers and starts the service, rerun-safe
Scope C (version display):
- config.GetAgentDisplayVersion (and the master getter) compose from
the bare number so a V-form injection no longer doubles the letter
(AV2.1.0 -> A2.1.0)
- node list view repairs stored AV-prefixed reports at assembly so
deployed agents read uniformly without an update
Scope D (production fix):
- share-link reality sni: when the inbound has a sing-box fragment,
sni is the fragment's tls.server_name - the only name the sing-box
REALITY server serves. The previous rule picked a uniformly random
serverNames entry per generation, which xray tolerated but sing-box
refuses as an invalid connection. sid keeps its random pick: the
converter carries the whole shortIds list into the fragment, so
every listed sid is served.
agent_nodes gains probe_only; getConfig always serves the flag and withholds the sing-box payload (null config, empty hash) for flagged nodes while probe tasks, fast interval, stat iface and update intents ride as usual. The agent gates both core branches when the local agent.json preset or the master flag is on, retires a running core once (best-effort tail flush, switchover bookkeeping untouched so turning the flag off self-heals through the existing hash-current-but-not-running path), and makes the traffic cycle an explicit no-op. Panel: node create/update accept probeOnly, the node view overlays it from the binding, the node form gains a switch (carried into the generated install command), the list shows a probe-only tag in the core-version cell, and install-agent.sh --probe-only writes the preset, skips the core download/self-check and inherits the flag on no-arg reruns.
- 0: sing-box gen overrides fragment listen/port from the inbound row
(empty listen -> "::"), Update/Add recompute the stored fragment;
non-loopback E2E against the real core binary.
- 1: agent fetches the sing-box core from the Gitea release when
missing, self-checks it, and only then latches the switch.
- 2: node list shows the sing-box core version (heartbeat field,
persisted on the node row), xray version as fallback.
- 3: public-page fallback returns 404 to anonymous visitors when the
page is disabled.
- 4: settings restart hint bar removed, dead i18n keys cleaned.
- 5: two PUT calls missing JSON headers fixed (audit: only those two),
batch probe-task creation endpoint + UI.
- 6: cf-probe retirement card and coverage pipeline removed.
- 7: generated vless links no longer carry spx (panel export + sub);
parser still accepts spx; golden fixtures updated.
- probe batch: dedicated probe settings tab (public-page settings,
tasks, per-node meta), retention_days editable, per-node traffic
calibration + stat-interface pinning, runtime metrics split into a
lightweight fast report (default 3s, 1-60s adjustable).
- 8: sing-box core processes start with GOMEMLIMIT=32MiB, GOGC=50.
- 9: dead /getTwoFactorEnable docs entries removed (frontend call and
contract entry already gone at base; verified by grep).
Sing-box becomes the only runtime payload (master serves
singbox_config only; agents switch on its arrival, flush and
retire xray, roll back to xray on activation failure). Plus the
two rehearsal-caught accounting fixes: stats registration needs
all three name lists (recording gate enforces the switches), and
fragment tags now equal panel row tags so inbound totals land.
