Why windows only? |
Restart now returns instead of exiting when the new instance cannot be started, and the prompt says so. ExitForAuroraWindowClose is back to its original signature. On Linux and macOS the relaunch uses posix_spawn. The runtime rejects any command-line arguments, so the new instance is started with only its own path. Inherited descriptors are marked close-on-exec first: unlike Windows, where CreateProcess is told not to inherit handles, a spawned process otherwise keeps the old instance's sockets and devices open.
Fixed, not tested on Mac yet though. |

_NSGetExecutablePath to query the required size and allocate a buffer

the allocated path for posix_spawn, while keeping the existing non-macOS path
handling unchanged.

Release controllers before the new instance starts.
RelaunchSelf() starts the child before ExitForAuroraWindowClose() calls ReleaseControllers(). The child can therefore initialize while the old instance still holds its controllers. Preserve the running instance on launch failure, but arrange for controller release to complete before the child initializes. This is the cleanup order required by the PR objective.

Restart now stops rumble before the new instance is spawned and leaves the LED alone. The new instance sets its own LED, so resetting it here was both unnecessary and a race: this process could turn it off after the new one had turned it on. A failed relaunch therefore leaves the LED as it was, with only rumble stopped, which the game re-issues on its next event. ReleaseControllers takes resetLeds, and its report-flush delay now runs whenever a controller is connected, not only when an LED was written. On macOS, _NSGetExecutablePath is asked for the required size first rather than failing when the path exceeds PATH_MAX, matching ExecutableDirectory.
