The optimistic Connecting paint and the Idle/stale-Connected
suppression lived in the tray's applyStatus, so only the tray got the
smoothed-out transition during a profile switch — the React Status
page (useStatus hook in frontend) subscribes to the same
netbird:status event and was seeing the raw daemon stream, complete
with the Disconnected blink.
Move the policy one layer up into the Peers service, between
SubscribeStatus and the Wails event bus, so every consumer downstream
sees the same filtered stream:
* Peers gains BeginProfileSwitch / CancelProfileSwitch / shouldSuppress.
BeginProfileSwitch sets the in-progress flag and emits a synthetic
Connecting status so both the tray and React paint Connecting
immediately. shouldSuppress swallows the daemon's stale Connected
(peer-count teardown) and transient Idle (Down between flows)
until Connecting / NeedsLogin / LoginFailed / SessionExpired /
DaemonUnavailable indicates the new profile's flow has started,
or a 30s safety timeout fires.
* ProfileSwitcher.SwitchActive calls peers.BeginProfileSwitch when
wasActive (prevStatus was Connected or Connecting) — the only
cases where the daemon emits the blink-inducing sequence. Other
prevStatuses already terminate cleanly on Idle.
* Tray loses its switchInProgress fields, applyOptimisticConnecting
helper, applyStatus suppression switch, and switchProfile's
optimistic-paint call. handleDisconnect now calls
Peers.CancelProfileSwitch alongside cancelling switchCancel, so
the abort path bypasses the suppression filter and the daemon's
Idle paints through immediately.
The full prevStatus -> action / optimistic label / suppressed events
matrix now lives in the ProfileSwitcher struct godoc, with the
suppression-rule-per-incoming-status table on the Peers struct
godoc — together they describe the click-time policy and the
stream-filter behaviour without duplication.
Wails bindings need regenerating to pick up Peers.BeginProfileSwitch
and Peers.CancelProfileSwitch.
The Fyne UI used to write the active profile to both fronts on every
switch (profile.go:264-273): the daemon SwitchProfile RPC for
/var/lib/netbird/active_profile.json, then profileManager.SwitchProfile
for the user-side ~/Library/Application Support/netbird/active_profile.
The Wails ProfileSwitcher only kept the first.
Without the user-side mirror, a UI tray switch updates the daemon's
state but the CLI ProfileManager.GetActiveProfile() still returns the
stale "default". The next "netbird up" then sends ProfileName="default"
in the Login/Up request, and the daemon silently switches back to
default, reverting whatever the user just picked in the tray.
Mirror the daemon switch with profilemanager.NewProfileManager().
SwitchProfile after the daemon RPC succeeds. The daemon stays the
authority — a user-side write failure is logged as a warning, not a
hard error.
The UI never needs to block on Up — status updates flow via the
SubscribeStatus stream. Hardcode Async:true in Connection.Up and remove
the Async field from UpParams so frontend callers are unaffected.
Down and Up(async=true) are both fast RPCs; no background goroutine
is needed. SwitchActive is now fully synchronous — the tray wraps the
call in its own goroutine, and Wails handles React calls similarly.
Switch RPC errors are now returned synchronously to the caller so the
tray can show a toast immediately on invalid-profile or other early
failures. Down and Up run in a background goroutine so the caller
returns fast; Up still uses async=true so the goroutine is short-lived.
The daemon's Up RPC previously always blocked in waitForUp (up to 50s)
until the engine connected. The UI does not need this — status updates
already flow through the SubscribeStatus stream.
Add bool async = 4 to UpRequest. When true the daemon starts
connectWithRetryRuns and returns immediately; the CLI path (async=false,
the default) is unchanged.
ProfileSwitcher.SwitchActive now sets Async:true so all three RPCs
(Status, Switch, Down, Up) return quickly. The background goroutine and
its associated race condition are removed entirely.
Both the tray and the React Profiles page previously had separate
switching logic: the tray applied a status-aware reconnect policy
(Down for error states, Up only when previously Connected/Connecting),
while the React page always called Switch + Up unconditionally with no
Down for LoginFailed/NeedsLogin/SessionExpired.
Introduce a single ProfileSwitcher service that encapsulates the full
reconnect policy. SwitchActive queries the current daemon status, calls
Switch, and launches Down/Up in a background goroutine so the caller
returns immediately after the Switch RPC completes. Both the tray and
the React Profiles page now delegate to this service.
Export the daemon status string constants (StatusConnected, etc.) from
the services package so tray.go no longer duplicates them as private
constants.
