fix(desktop): keep windows alive after theme pack install - #619
Merged
Conversation
Settings → Themes Install was calling a full PluginHost remount and palette activate in the same turn. On Linux AppImage that tore down BrowserWindows and the process exited even though the pack landed. Harvest and activate first, then broadcast plugins:reload. PluginHost now syncs by id so a new pack does not unload every plugin. Reload never app.quit / process.exit / win.close. Co-authored-by: Tomás Maritano <tomymaritano@gmail.com>

sortPlugins(next) before computing lifecycle actions, then pass the sorted valid
manifests to nextPluginHostActions instead of sorting only activate. Preserve
the resulting dependency order for activations and ensure dependents whose
dependencies were removed are included in unload handling.

sortPlugins(activate) could not see already-active dependencies, so a new extension whose base was running was skipped, and an extension whose base left the scan stayed loaded. Sort next first, then diff. Co-authored-by: Tomás Maritano <tomymaritano@gmail.com>

Summary
Settings → Themes → Install was quitting the Linux AppImage immediately after a successful pack download. The pack landed on disk (
data/plugins/theme-limestone) and showed as In use after relaunch; the process still exited on the Install click.Install-complete now harvests and activates the palette in Settings first, then broadcasts
plugins:reload. That reload is a send-only IPC — notprocess.exit,app.quit,win.close, orwebContents.reload. PluginHost syncs by plugin id so a newly installed theme pack is activated without unloading every other plugin (the remount that raced palette activation). Incremental sync sorts the full desired set first so a new dependent of an already-active plugin still activates, and a dependent whose base left the scan is unloaded.OFFICIAL_THEMESstays empty. Browse / Other package is unchanged. No version bump.Type of Change
