Sequential packet recording #16

Closed cclaessens closed 7 years ago

cclaessens commented 7 years ago

Currently only packets with matching f and t ID are processed and missing packets result are skipped and a new event is started.

Running psyllid with the fpa receiver resulted in a lot of warnings from the roach_receiver about Improper packet sizes and a small egg file. After adding a warning which is printed when the packet size is as expected it seems that in a 100ms run 1 out of 2 packets have the wrong size. To produce the following output I also added a debug line ("acquisition break") which is written when the streaming writer doesn't get the packet it expects. Acquisitions are always only 1 record long.

In a run with the socket receiver the packet sizes seem to always be as expected and acquisitions have more records. Breaks occur regularly too.

I'm not able to replicate this problem. Are you sure you're using the latest commit? I had something like this happening yesterday, but I fixed the bug in that case. I'm writing this as of commit 3fce23f.

Nevermind my last comment. I hadn't been performing a run. I do replicate the problem.

This was fixed in commit 8da44ce643886435d550c2a13db9468bf80b96c0
