hi team, i am new to xpra.
due to current covid situation, i do require the UDP transport (have a long distant link and somewhat high delay). yes, i've seen the "experimental" note, nevertheless i'd like to report the following:
if i use the plain tcp transport, things work fine. if i try to use udp, i get
Traceback (most recent call last): File "E:\Xpra\tags\v3.0.x\src/xpra/net/udp_protocol.py", line 184, in send_control AttributeError: 'UDPClientProtocol' object has no attribute 'send_control_failed'

=====
i think this can be easily fixed, in case python is your native language ;-)

config: no changes
Thanks for the report, that's now fixed in r25759 and will be included in the 3.0.8 release. (you can apply it by hand to your installation as it is tiny)
That said, if you're going to use UDP, I recommend switching to the beta channel, which has more fixes and improvements for the UDP transport.
Please bear in mind that TCP may still perform better than UDP at this point.
i've modified udp_protocol.py on both server and client. this fixes xpra attach, but - as said - after few seconds of idle time a spinner and some errors appear on the server. i've attached :0.log from the server.
at the client:

That doesn't make sense, the caller clearly has no arguments:
fail_cb_seq()
Can you try this patch:

And tell me what warnings you see?
in the meantime i could compile svn-r25730 on the linux-client side (fedora30).
not sure, if i can compile it also on the server side (centos7). i'll try your suggestion on the server first.
svn-r25730 on the client and xpra-3.0.7-r25627 on the server gives:

after some time (of running fine).
seems, that sometimes large UDP packets are generated, which are not handled properly.
i'll try to compile the svn trunk on the server later!
on the client. the server still reports
No send_control_failed
warnings?
Warning: found large packet
Yes, there's a leak in trunk - will fix.
here's the _send_control_failed_ on the server ;-) i've used xpra-r25767 on the client and xpra v3.0.7-r25627 + my and your patch on the server. server:

will try to compile svn-r25767 on centos7 now.
AttributeError: 'tuple' object has no attribute 'cancel_control_timer'
That's a completely different error, probably caused by some of the changes you made - the line numbers don't match the source for 3.0.x or trunk, and self
would have to be defined and be a valid object (not a tupel) to be able to reach send_control_failed
.
Please post the source file you're using or a diff comparing it with the current 3.0.x
i gave up on compiling the SVN version on centos7. i am using the binary-beta versions now and switched from centos7 to 8 on the server: xpra-4.0-0.20200327r25797.el8_1.x86_64. client is still fedora30: xpra-4.0-0.20200327r25797.fc30.x86_64.

after applying r25847 to the binary release xpra-4.0-0.20200327r25797, i do not get anymore python errors. (so far) only timeouts appear, after a while. might be much more difficult to debug (maybe network packet trace required).

try not to wait for too long if a sequence is just not coming through
I think the problem occurs when the "control" packets end up being too big to fit in one UDP frame. This seems to trigger a storm that we never recover from.. Too late for v4 unfortunately.
I don't have time to look into this.
