    Mongoose is now a submodule (making us a "superproject" :)).<br>
    <br>
    Note: I think you'll need to manually do a "git submodule init"
    after the next pull, but that may depend on your git version (?).<br>
    <br>
    I've pushed my changes regarding the ESP logging and the
    SO_REUSEADDR patch to our mongoose fork.<br>
    <br>
    I've also added a config option for the mongoose debugging (default
    disabled). Enabling now also includes time deltas (µs resoltion) for
    mongoose.<br>
    <br>
    Mark / Steve, if you'd like to check my changes first, I'll create a
    pull request tomorrow.<br>
    <br>
    Regards,<br>
    Michael<br>

Back in November we discussed this problem of the client's half of the
connection being left open.  Then as now, you commented that mongoose
sends a close event (MG_EV_CLOSE) for each open connection when the
interface went down.

It does send a close event, but not until after the wifi is already
shut down so closing the socket at that point does not send any packet
to the client.  I decided to punt on that issue, though, because
manually shutting down wifi is not an important use case.  The more
likely case is that wifi connectivity is lost due to motion or other
causes and in that case no close packet can be delivered anyway.

I interpreted Michael's message to be referring to a problem with
ports on the server (OVMS) end.  That is, to say that mongoose didn't
clean up LWIP state properly.  Michael, can you explain a bit more?

But ssh client connection is still up on my workstation. Looks like
the MG_EV_CLOSE events came in after the SSH server was stopped.

I repeated the test, but with event logging on:

MDNS exits quicker because it responds to the network.wifi.down message, while ssh uses the network.mgr.stop event. In a clean shutdown there is a difference.

Perhaps we should issue network.mgr.stop earlier? However, even if we close the connections from our end, I’m not sure if the packet would make it through to the other end before the wifi disconnects.

Regards, Mark.

be correlated to this: sockets don't get closed when losing the

not tested). To reproduce, switch the Wifi network with an open
