fix(cash): race between give transactor dispose and start on quick bg/fg#696
Merged
Conversation
When the user backgrounds and foregrounds quickly during an active give-bill flow, cancelAwaitForGrab() can dispose the transactor between with() and start(), nulling owner before start() reads it. Fix by making the transactor self-protecting: - Reorder dispose() to cancel the scope before nulling fields - Check scope.isActive at the top of start() to bail out if disposed Bugsnag: 6a021d748c3285d1a5987c43 Signed-off-by: Brandon McAnsh <git@bmcreations.dev>
