Grouping "hides" packets until the group is complete

[smunaut]

What happens is that packets are only shown on the UI when the "group" logic flushes and think the group is done. That logic is fine if you're viewing a file or a capture that's ended, but when doing live capture, this presents a view that's far from reality.

Especially when debugging issues where transactions are invalid / incomplete, a lot of packet just end up in limbo and never shown.

I think ideally any packet that has been received should be shown in the UI, and so "incomplete" groups should already be there and progressively filled / updated. That's unfortunately not trivial :/

Yep -- the whole analyzer stack is currently missing periodic "tick" that allows things to e.g. time out while being aggregated.

It also might be nice to have a feature that allows us to gather up "in progress" packets and display them somewhere in the UI -- though most timeouts should prevent them from sticking anywhere for any appreciable amount of time.

Possibly caused by the same issue as suggested on Discord:

I'm trying to use ViewSB to sniff USB mouse communication with openvizsla backend (./viewsb.sh openvizsla --speed=low), but I'm only seeing control requests, not the interrupt ones. At the same time I'm seeing all requests properly when using the original OpenVizsla software (./software/host/ovctl.py sniff ls), and when using the usbmon backend of ViewSB (./viewsb.sh usbmon --file=/dev/usbmon1).

Closed in preparation for archiving the repository. We have replaced ViewSB with Packetry.
