Bug in live version: Trace containing two connections are missmapped

[janrueth]

Describe the bug
It seems that QVIS does not properly handle two connections in the same trace.
A second connection seems to be mapped to the first connection and, e.g., initial frames are interpreted as retransmission (see attached screenshot). It also lacks all answers from the second connection.

To Reproduce

• How did you load the file?
  Via QUIC Tracker: https://quic-tracker.info.ucl.ac.be/traces/20200321/532
• Which visualization had the error?
  Sequence

Expected behavior
Not mixing up two connections into one sequence. I suggest having a connection drop down menu that allows selecting a connection from a trace.

Hello Jan,

Thanks for reporting. This (and the other issue) are more issues with our pcap2qlog tool than qvis itself, but when using qvis directly from quictracker that's of course abstracted out for the end user.

This one especially seems like a weird one, so having a reproducible source will definitely come in handy, thanks!

Hi Robin,

ah okay that was not obvious to me.
Do you want me to file the bug report with pcap2qlog?

Hello Jan,

No, sorry that wasn't clear. I mainly wanted to make it clear that if you have a "proper" qlog (e.g., exported from an implementation directly) instead of a transformed pcap, that qvis itself should handle that just fine (in case you want to test or use qvis in alternate ways).

Since I'm the primary maintainer across all these projects, it doesn't really matter where the issues are filed atm :)

ah, got it!
