PR #26070: Size comparison from f25702c to eee1f6e Increases (1 build for cc32xx)
Full report (1 build for cc32xx)
|
When shutting down a controller, we just destroyed its pending session setups without notifying their consumers. This leaks, becase those consumers never get a "setup has failed" notification and hence can't clean up properly. A simple way to reproduce is to build darwin-framework-tool without ASAN enabled, then run: MallocStackLogging=YES leaks --atExit -- darwin-framework-tool onoff toggle 0xDEADBEEF 1 when no node with id 0xDEADBEEF is commissioned. The fix is to send notifications when tearing down the OperationalSessionSetup, if we have not notified yet.
