lib/tsocket: optimize tdgram_recvfrom_done() into tdgram_recvfrom_send()

2025-07-17T08:59:37+00:00

For callers using tdgram_bsd_optimize_recvfrom() it is every useful
to know it data was already waiting in the socket.

In that case the result from tdgram_bsd_recvfrom_send() would
already report tevent_req_is_in_progress() as false.

But the result of tdgram_recvfrom_send() available to the
caller would see tevent_req_is_in_progress() reporting true.

With this change also the result of tdgram_recvfrom_send()
would report tevent_req_is_in_progress() as false,
which will be useful for callers, which would otherwise
set a timeout on the request.

async_sock: move samba_socket_{poll,sock,poll_or_sock}_error() from util_net.c to async_sock.c

The change to LGPL is also intended.

It will be used in the the next commit that adds
wait_for_error_send/recv.

lib/tsocket: add tstream_bsd_fail_readv_first_error()

2023-10-24T09:36:37+00:00

This gives the caller the option to fail immediately if
TEVENT_FD_ERROR appear even with pending bytes in the
recv queue.

Servers typically want to activate this in order to avoid
pointless work, while clients typically want to read
pending responses from the recv queue.

lib/tsocket: make use of TEVENT_FD_ERROR in tstream_bsd_fde_handler()

2023-10-24T09:36:37+00:00

This makes the logic introduced to fix bug #15202 simpler.

While developing this I noticed that a lot of callers
rely on the fact that they can read the pending bytes out
of the recv queue before EOF is reported.

So I changed the code handle TEVENT_FD_ERROR together with
TEVENT_FD_READ in a way that keep the existing callers happy.

In the next step we'll add a way to let callers opt-in in order
to fail immediately if TEVENT_FD_ERROR appears (even if there
are pending bytes remaining in the recv queue).

This mostly cosmetic, but now that we have TEVENT_FD_ERROR we should use it.
