fix(ui): keep sidebar state and console logging across close and logback resets - #1955
Merged

Conversation
…ack resets While the client closes, removing the open Hub tab fell back to an older history entry and opened or closed the sidebar to match it, which wrote runelite.clientSidebarClosed during the exit window. removeNavigation now keeps the current sidebar visibility while closing, so toggleSidebar is a no-op and nothing is written. A logback reset (scan=true reconfiguration) detached and stopped the console appender, and the recreated STDOUT ConsoleAppender wrote through the System.out tee again. ConsoleLogAppender is now a reset-resistant LoggerContextListener: on reset it reattaches itself and rebinds the STDOUT appenders to the real stdout on the first event after the new configuration attaches them. On context stop it detaches itself. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LjtEMzQHGuq4M1Mpqk9pPV

WalkthroughClientUI now preserves the sidebar’s current visibility when it removes a navigation entry during shutdown. ConsoleLogAppender now installs and uninstalls as a logger context listener, reattaches after context resets, and retries stdout binding during append. Tests cover sidebar shutdown behavior and appender routing across reset and shutdown. Priority: ⬇️ Low Merge Risk: 🔵 Low · up to

Rate-limit pending stdout rebinding attempts.
The supported shaded-jar launch path permits a -Dlogback.configurationFile override before -jar. With a valid file-only or stderr-only configuration, ConsoleLogAppender remains installed after a reset, but bindStdoutAppenders returns false. Each log event then scans every logger and its appenders.
This adds avoidable per-event CPU work that grows with the logger and appender count. Retry at a bounded rate while rebindPending is true. Keep retrying so a later configuration that adds STDOUT can still rebind it.

Follow-ups from the review of #1954.
Problem
1. Sidebar state written while closing. While the client closes, MicrobotPluginManager stops the Hub plugins, and
ClientUI.removeNavigationremoves their tabs. When the removed tab was the open one, it calledopenPanel(entry.navBtn, entry.sidebarOpen)with an older history entry. That goes throughtoggleSidebar, which writesrunelite.clientSidebarClosedwhenever the visibility changes. #1954 stopped the tab write but not this one.In the real client, the reachable case is the reverse of the one named in the review. Removing the selected tab while the sidebar is visible makes JTabbedPane select a neighbour, and the change listener pushes
(visible, neighbour), so the fallback matches the current state and nothing is written. When the sidebar is hidden, the listener pushes nothing. The fallback is then an older(true, X)entry, so the sidebar reopens andclientSidebarClosedis unset during the exit window. A user who closed the sidebar can therefore get it back open on the next start. I reproduced this live (see Testing).2. Console appender lost after a logback reset. In dev runs from an exploded classpath,
logback.xml(scan="true") can trigger a reconfiguration. TheLoggerContextreset detaches and stops the programmatically attachedConsoleLogAppender. The newSTDOUTConsoleAppender targetsSystem.outagain, which is the console tee. The review said the console stops receiving lines, but that is not quite what happens: lines keep reaching the panel through the tee, in the long STDOUT format. The console appender stays detached for the rest of the session, and the STDOUT binding from #1951/#1954 is gone. If the appender were reattached without rebinding STDOUT, every line would show twice.Change
ClientUI.removeNavigation: whileclosing(the flag fix(ui): keep the saved sidebar tab and stdout intact while closing #1954 added), callopenPanel(entry.navBtn, sidebar.isVisible()). The sidebar keeps its current visibility,toggleSidebarreturns early, and noclientSidebarClosedwrite happens in either direction. Outside closing, behaviour is unchanged. This is a one-line change in the upstream file. The rest of the ClientUI diff replaces the five appender-setup lines withConsoleLogAppender.install(...)and drops the now-unusedLoggerimport.ConsoleLogAppenderis now a reset-resistantLoggerContextListener, installed throughinstall(context, stdout, consumer):onReset: restarts the appender, reattaches it to root, and marks a STDOUT rebind as pending.onResetruns before the new configuration exists, so the rebind cannot happen there.append: while a rebind is pending, runsbindStdoutAppenders. The pending flag clears only once at least one STDOUT appender was actually bound. A line logged between the reset and the end of reconfiguration therefore does not use up the rebind. The appender is attached before the new STDOUT on root, so the first line after reconfiguration is rebound before STDOUT writes it, which prevents double lines.onStop: detaches and stops itself, becauseLoggerContext.stop()callsreset()first.uninstall()removes the listener (the tests use it).Testing
./gradlew :client:runUnitTests --offline: 2368 tests, 0 failures, 2 skipped.ClientUITest.removingTheOpenTabWhileClosingDoesNotReopenAClosedSidebar: without the fix it fails withNeverWantedButInvoked: unsetConfiguration("runelite", "clientSidebarClosed"). The test helper's change listener now pushes history like the real ClientUI listener, so the history matches the live client.ConsoleLogAppenderTest.reconfigurationKeepsTheConsoleAppenderAndStdoutBinding: realJoranConfiguratorreset and reconfigure. With no listener (the old code), the console appender gets 0 lines (expected:<1> but was:<0>). With reattach but no rebind, the line also reaches the panel through the tee (expected:<0> but was:<1>, a double line).ConsoleLogAppenderTest.lineLoggedBeforeReconfigurationEndsDoesNotLeaveStdoutUnbound: logs between reset and reconfigure. It fails the same two ways.ConsoleLogAppenderTest.stoppingTheLoggerContextDetachesTheConsoleAppenderguards the newonStop. It also passes on the old code, because there was no listener.-Dlogback.configurationFileset to a copy of the config withscanPeriod="1 seconds", and a probe bumped the file's mtime twice. The status list showed 2 × "Will reset and reconfigure context". After each reset the root appenders wereConsoleLogAppender(started),STDOUT(stream =CloseShieldOutputStream) andFILE. Probe lines logged after the reset appeared once in the panel, in the short console format, and once in stdout.closing=truethe sidebar stayed hidden andclientSidebarClosedstayedtrue. Withclosing=false(the pre-fix path) the sidebar reopened and the key was unset.clientSidebarTab=Notesand noclientSidebarClosed. After a restart the sidebar was visible with Notes selected. I restored the original state (no saved tab) afterwards.Not verified: no Hub plugin with a sidebar panel was installed in the test profile. I exercised the closing path with a probe nav button and a forced
closingflag, not with a real Hub plugin being stopped at exit. I also did not reproduce the race where a config flush persists the value during the exit window; the change removes the write itself.🤖 Generated with Claude Code
