This likely affects no system but VERT.

Log Message:
Set node "interrupt" flag to try to gracefully disconnect user blocking event

When a timed event is configured to run "exclusively", all nodes need to not be in in-use. As it was, after waiting 60 minutes for the online user(s) to
notice they'd run out of time and disconnect, we'd just (rather ungracefully) close the sockets used by such node(s) connections. This results in same logged errors about trying to send to bad socket descriptors and provides no feedback to the user about why they were disconnected.

Since we have the node interrupt flag (which hopefully, all scripts are checking via node_sync) - use that to try to more gracefully terminate the user's session/connection after 30 minutes of waiting for the user to disconnect.

If after 60 minutes of waiting, the node is still in-use, we still do the socket disconnection method.

Log Message:
Add and improve log messages (warnings, errors) in input_thread()

... mainly to help understand (still a mystery) how the first check of
the inbuf free space could pass (there's at least one byte available), but
the second check (after recv()) fail and the "INPUT BUFFER FULL" message gets logged - that doesn't seem possible unless there's some other thread stuffing chars into the inbuf (and that shouldn't be happening with the exception of node spying).

While investigating this mystery, I saw there missing node numbers and other helpful data (e.g. the number of bytes received to that point) from some of
the log messages. And in some SSH error conditions, nothing would be logged though the input_thread's loop would terminate (break), so added some log messages for "Operation complete" and "Timeout" which had explicit handlers with no log output.

Increase the received byte counter from 32 to 64-bits.

Stop using the 'rd' varible for multiple purposes, improving readability.

Not root-caused, just worked-around/avoided. Most likely there's a js cleanup happening (e.g. destroying the JS runtime) the same time that js_init() is executing from the event_thread(), so just avoid this by not calling js_init() while already set to terminate the server.

src/sbbs3/main.cpp
Log Message:
Add some passthru thread debug log messages

To hopefully help identify the cause of issue #1038

The theory being that the client socket was disconnected while running an external program (sexyz in this case) and this check at the end of external() (the *nix version) might have a race condition with the passthru thread terminating due to disconnection as well:
if (!(mode & EX_STDIN)) {
if (passthru_thread_running)
passthru_socket_activate(false);
else
pthread_mutex_unlock(&input_thread_mutex);
}
in which case it would try to unlock the input_thread_mutex that it did not own. I'm not clear why that would cause the pthread_mutex_destroy() call to fail (on input_thread_mutex) but maybe it does.

It's possible the configuration was upgraded (e.g. by update.js) before any timed events have run, so the time.dab could be short. Just zero-initialize (and don't log any errors) if there's trouble reading a legacy timestamp from time.dab or qnet.dab.

Simplify/correct the node status fixup upon client connect

- when we treat a non-WFC node status the same as WFC because the node_socket
is invalid, don't call lprintf(LOG_CRIT, ...) with the node logged. That's
ultimately going to call errormsg() which is going to try to increment the
node's critical error counter and fail or deadlock because the node's
record is already locked. Log the error after we call putnodedat() and the
node record has been unlocked.
- The "status is WFC" while the node_socket is valid check would always fail
because we already checked the node_socket validity at the top of the loop
so just remove this check/error message as dead code

Log Message:
sbbs3 terminal server: drop unsent goodbye output before close_socket

In the four listener exit paths that queue output via the listener
pseudo-sbbs (CLIENT BLOCKED for ip.can / host.can, "no nodes
available", node init failure), call sbbs->rioctl(IOFB) right after flush_output() and before close_socket(). Without this, any
text/badip.msg / badhost.msg / nonodes.txt residue that didn't make
it out within the flush timeout sits in the ring buffer; when the
output thread next wakes it tries to send the leftover on the
now-closed FD, and the failed send logs a noisy warning (e.g.
"!ERROR 22 (...)" or "!ERROR 58 (...)" sending on socket).

This is the same idiom as the existing rioctl(IOFB) at the start of
the per-connection setup (main.cpp:5795) Ä purge stale buffer state
before changing socket lifecycle.

It does not eliminate the race entirely: data already pulled from
the ring buffer into the output thread's linear buffer is still sent
(or attempted), since rioctl operates on the ring buffer only. The
remaining noise is handled separately by demoting the typical
post-shutdown send errors (ESHUTDOWN, EINVAL) to LOG_NOTICE.

Log Message:
sbbs3 terminal server: include socket/protocol/IP in output_thread send-error logs

Three coordinated changes to output_thread's SOCKET_ERROR handling:

* Switch all six log lines from "<node-name> ..." (using sbbs->client_name
like "Terminal Server" / "Node N") to the standard "%04d %s [%s] ..."
prefix used by every other connection log line in the file. This
groups send errors with the matching "Connection accepted",
"!CLIENT BLOCKED", etc. lines for easy correlation. Capture
client_socket.load() once into a local since the cascade reads it
six times (it's std::atomic).

* Populate the listener pseudo-sbbs's client.protocol and client_ipaddr
per-connection. These were previously only set inside sbbs_t::init()
for per-node sbbs's (main.cpp:3639), leaving the listener's
output_thread with empty strings to print.

* Demote ESHUTDOWN and EINVAL send errors to LOG_NOTICE alongside the
existing ENOTSOCK / ECONNRESET / ECONNABORTED handlers. Both are
the typical errors raised when the listener races with close_socket()
on a blocked client (post-shutdown / mid-close socket state).
Treating them as expected disconnect noise matches the existing
pattern. Note: on POSIX, EINVAL from send() can theoretically
indicate a programming bug rather than a socket-state race, but in
practice it's the same race as on Windows and the noise reduction
is worth the small risk of masking.
