commit b553457f68bf8a34f3e9f3266d361e9a99530017 Author: Takashi Yano <[email protected]> Date: Fri Jun 2 10:19:18 2023 +0900 Cygwin: pty: Additional fix for transferring input at exit. The commit 3456e8b7db5b does not fix transferring input at exit appropriately. If the more than one non-cygwin apps are executed simultaneously and one of them is terminated, the pty master failed to send input to the other non-cygwin apps. This patch fixes that. Fixes: 3456e8b7db5b ("Cygwin: pty: Fix transferring type-ahead input between input pipes.")
