    Fixes #30419.

    Make sure that ellswift computation is complete in the NetworkThread in test/functional/p2p_v2_misbehaving.py before sending the ellswift in the MainThread.

    One way to reproduce this failure on master would be:

    I could verify that the issue I see with sleep(3) is fixed with the change here. However, when I increase the number from 3 to 5 or 10 I still see other errors, so there may be more potential for race conditions here.

    The two failures I saw:

    It seems like at least it might be a good idea to make the explicit timeouts in the test a bit less aggressive, i.e. change timeout=5 to timeout=10 or so in the two places.

    Tested with the sleep() statement added into generate_keypair_and_garbage() in master and the PR branch. Failure only occurred on master (as expected).

However, when I increase the number from 3 to 5 or 10 I still see other errors, so there may be more potential for race conditions here. @fjahr good find! both the errors which you shared are because of disconnections due to InactivityCheck triggers from setting peertimeout=3 in the test. I’ve increased it to peertimeout=5 for more leeway.

    It seems like at least it might be a good idea to make the explicit timeouts in the test a bit less aggressive, i.e. change timeout=5 to timeout=10 or so in the two places.

    I’ve taken your suggestion and made it to timeout=10.

    This means the test is idle for this time in wall clock time. You can use mocktime to fix this and also avoid intermittent issues on slow hardware. See for example test/functional/p2p_timeouts.py

    My recommendation would be to remove peer.wait_for_disconnect(), since it doesn’t do anything, and instead add an assert after the assert_debug_log scope to check the peer is disconnected.
    maflcko commented at 6:15 am on July 11, 2024:
    A more involved alternative would be to add a passing connection after the misbehaving one, then wait for the disconnect of the misbehaving one after the passing one is fully connected. This should allow to avoid using the debug log polling to sync on and proceed with the test.

    Ok, I see, the peer.wait_for_disconnect() immediately returns, as there is no connection yet, and doesn’t do anything.

    I meant it as a check so that we know if self._transport got reset to None at some point of time. (self._transport is set in connection_made() when the connection is opened irrespective of whether p2p connection remains connected or disconnected)

    Why is it required to set a timeout here at all? The log message should happen before the disconnect, which is waited on, no?

    Hmm yes, makes sense that we don’t need a timeout.

    A more involved alternative would be to add a passing connection after the misbehaving one, then wait for the disconnect of the misbehaving one after the passing one is fully connected. This should allow to avoid using the debug log polling to sync on and proceed with the test.

    I’ve used this idea!

    Can you explain what this means? sendSet is a boolean, so what does “populated” mean? Also, when removing peer2 the test works fine, no? What would the “wrong” error message be?
    stratospher commented at 1:36 pm on July 15, 2024:

    if the test is run in a loop, sometimes "socket no message in first %I seconds" is displayed and sometimes "V2 handshake timeout" is displayed.

    if sendSet is not set, “socket no message in first %i seconds” is displayed since that check is above the check for the handshake timeout in InactivityCheck().

    I’ve changed the sendSet vocabulary from populated -> set. open to better wordings.

    maflcko commented at 1:49 pm on July 15, 2024:

    if the test is run in a loop, sometimes "socket no message in first %I seconds" is displayed and sometimes "V2 handshake timeout" is displayed.

    I couldn’t reproduce this locally. Also, it seems odd that one member field of a peer affects the field of another peer.

    here’s a failure I get when removing peer2:

    Also, it seems odd that one member field of a peer affects the field of another peer.

    no, it doesn’t! I just want some way to wait some time so that sendSet for the same peer can get set. it will eventually get set but not immediately.

    we could replace:

    0peer2 = node0.add_p2p_connection(P2PInterface())
1assert peer2.is_connected

    with

    0import time; time.sleep(3)

    and it would do!

    maflcko commented at 2:11 pm on July 15, 2024:

    Ok, I see. Would an alternative be to wait until the RPC’s peer info bytessent or bytesrecv increased after the send_raw_message?

    Alternatively, I presume the reason that sendSet is set is because send_raw_message is executed. So the comment could simply say the this is to ensure the message sent is actually received.

    Anything is fine tough. I see now why it is needed.

    The ellswift bytes are computed in the NetworkThread and sent in
the MainThread. Add a `wait_until()` to make sure that ellswift
computation is completed in NetworkThread before sending it in
the MainThread. Also wait until bytes sent are actually received
and use mocktime for more robust disconnection checking.

    3 is the peer timeout, so you’ll have to change it to bump 2 here. Otherwise, the test will fail:

    Also, you’ll have to move it up by one line. Otherwise it is racy, because sometimes it will be bumped when the message was sent, and sometimes before the raw message was sent.

    3 is the peer timeout, so you’ll have to change it to bump 2 here. Otherwise, the test will fail:

    I didn’t follow. The inactivity check trigger runs only when we bump by > 3 and not when the bump = 3 right. I tried logging return node.m_connected + m_peer_connect_timeout < now; condition in ShouldRunInactivityChecks():

    0[net] [net.cpp:1968] [ShouldRunInactivityChecks] [net] Inactivity check does not run because 1721209275 + 3 >= 1721209275

    Also, you’ll have to move it up by one line.

    right, makes sense.
