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.

// Command xui-agent is the standalone Linux build of the 3x-ui node
|
|
// agent (agent/panel split, phase 1). Until the split, nodes ran the
|
|
// panel binary under the "agent" subcommand, shipping the whole web
|
|
// panel and the embedded frontend to every node. This entry links only
|
|
// the agent's own dependency closure (internal/agent plus config,
|
|
// logger, selfupdate, xray-api types and two util leaves), so the node
|
|
// artifact is a fraction of the panel binary while remaining a drop-in
|
|
// replacement for it:
|
|
//
|
|
// - invocation is unchanged: service units run
|
|
// "xui-agent agent [-config /etc/x-ui/agent.json]" (the bare
|
|
// "-config" form is also accepted for manual runs);
|
|
// - agent.json, the traffic baseline and the other state files keep
|
|
// their names, locations and formats;
|
|
// - the wire protocol with the master (register / heartbeat /
|
|
// config / traffic / probe-report / update intent) is byte-for-
|
|
// byte the internal/agent implementation the dual-mode binary ran.
|
|
//
|
|
// The agent lifecycle wiring below mirrors main.go's agent branch
|
|
// exactly — the same internal/agent package does the work either way,
|
|
// and cmd/xui-agent-windows is the Windows sibling of this entry.
