From c00cdefa1da17f60b3179704528582ef320e61b8 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 11 Dec 2018 16:55:31 -0500 Subject: [PATCH] on failed aio submission, set aiocb error and return value it's not clear whether this is required, but it seems arguable that it should happen. for example aio_suspend is supposed to return immediately if any of the operations has "completed", which includes ending with an error status asynchonously and might also be interpreted to include doing so synchronously. --- src/aio/aio.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/aio/aio.c b/src/aio/aio.c index dae97cc6..6d34fa86 100644 --- a/src/aio/aio.c +++ b/src/aio/aio.c @@ -280,6 +280,8 @@ static int submit(struct aiocb *cb, int op) if (!q) { if (errno != EBADF) errno = EAGAIN; + cb->__ret = -1; + cb->__err = errno; return -1; } q->ref++; @@ -303,8 +305,8 @@ static int submit(struct aiocb *cb, int op) if (pthread_create(&td, &a, io_thread_func, &args)) { pthread_mutex_lock(&q->lock); __aio_unref_queue(q); - errno = EAGAIN; - ret = -1; + cb->__err = errno = EAGAIN; + cb->__ret = ret = -1; } pthread_sigmask(SIG_SETMASK, &origmask, 0); -- 2.25.1
