Thread: pgsql: Add WL_SOCKET_CLOSED for socket shutdown events.
Add WL_SOCKET_CLOSED for socket shutdown events. Provide a way for WaitEventSet to report that the remote peer has shut down its socket, independently of whether there is any buffered data remaining to be read. This works only on systems where the kernel exposes that information, namely: * WAIT_USE_POLL builds using POLLRDHUP, if available * WAIT_USE_EPOLL builds using EPOLLRDHUP * WAIT_USE_KQUEUE builds using EV_EOF Reviewed-by: Zhihong Yu <zyu@yugabyte.com> Reviewed-by: Maksim Milyutin <milyutinma@gmail.com> Discussion: https://postgr.es/m/77def86b27e41f0efcba411460e929ae%40postgrespro.ru Branch ------ master Details ------- https://git.postgresql.org/pg/commitdiff/50e570a59e7f86bb41f029a66b781fc79b8d50f1 Modified Files -------------- src/backend/storage/ipc/latch.c | 79 ++++++++++++++++++++++++++++++++++++----- src/include/storage/latch.h | 6 ++-- 2 files changed, 74 insertions(+), 11 deletions(-)
