Retry interrupted system calls
Closed this issue · 2 comments
WaitCQEvents can return io_uring_enter: interrupted system call. It'd be nice if interrupted syscalls were automatically retried.
UPDATE:
ERRORS
EINTR
The operation was interrupted by a delivery of a signal before it could complete; see signal(7). Can happen while waiting for events with IORING_ENTER_GETEVENTS.
Thanks for participating!
Main idea of uring package - designed as similar as possible to liburing. So i think uring package is to low level for have a logic about handling EINTR. But i'm agreed that this logic must exists. I think better place for it - one level up - in reactor package, or any other uring caller. For example:

I'll close the issue for now. Feel free to reopen when you've got more questions
