Packets dropped in v1.0, but correct in v0.1.2. #15

Closed keck-in-space closed 3 years ago

keck-in-space commented 3 years ago

Hello,

I have a script written that works fine with ballcosmos v0.1.2, but fails to collect all packets when using v1.0.0. I am running COSMOS v4.4.2

I have tried the script with os.environ["COSMOS_VERSION"] = "4" running ballcosmos v1.0.0, but it still fails in the same way.

What I am seeing is that after subscribing to a packet, the first few are dropped/missing with v1.0.0, but are always captured with v0.1.2.

packet_queue = subscribe_packet_data([[PROJECT_NAME, DATA_PACKET_NAME]])
while True:
     # packets are missing here when using v1.0.0. They typically start a few behind the stream (4-6 packets are dropped)
    packet_data = (get_packet_data(packet_queue)[0])

Hi @keck-in-space I just pushed an update the ballcosmos master branch to 1.1.0 and removed a lot of the changes I did for 1.0.0 if you can give it another try and see if you have the same problem. I was unable to reproduce the problem but we are going to keep ballcosmos for Cosmos v4 and will have a separate library for Cosmos v5.
