Mongoose is now a submodule (making us a "superproject" :)).<br class="">
<br class="">
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 class="">
<br class="">
I've pushed my changes regarding the ESP logging and the
SO_REUSEADDR patch to our mongoose fork.<br class="">
<br class="">
I've also added a config option for the mongoose debugging (default
disabled). Enabling now also includes time deltas (µs resoltion) for
mongoose.<br class="">
<br class="">
Mark / Steve, if you'd like to check my changes first, I'll create a
pull request tomorrow.<br class="">
<br class="">

Michael<br class="">

I’ve done the fork at the github level, and set appropriate

<div class="">Can you set it up as a git subproject within ovms3?
That way changes get pulled in automatically?</div>

<div class="">Regarding the changes to mongoose itself, let’s try
to do these in a way that can be pushed back to cesanta upstream
as valuable patches. For example, this change to support
SO_REUSEADDR is an ESP32 feature and can be enabled for that
platform.</div>

My v3 tree switched to 3.1 now, so not so easy ;-( I
really need to work out a way to do automated builds
(switching sdkconfig appropriately).
<div class=""><br class="">
</div>
<div class="">I think you may be correct - it is
probably not the listen socket that has the issue,
but the actual connection socket.</div>
<div class=""><br class="">
</div>
<div class="">Can you try enabling the option
SO_REUSEADDR in menuconfig? That should allow the
listen socket to be opened, even if a connection
socket is in TIME_WAIT state (assuming the mongoose
library sets SO_REUSEADDR correctly).</div>
</blockquote>
<br class="">
It doesn't out of the box, as it still assumes LWIP does
not support it, but after disabling the exclusion in
mg_open_listening_socket() this works.<br class="">
<br class="">
So, another patch for mongoose… maybe we really should
fork mongoose. If you don't have an objection, I can do
that later on.<br class="">

<pre class="" wrap="">Mark,
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?

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.
