How to analyze the failed items in the report #914

Closed Vvooi closed 2 years ago

Vvooi commented 2 years ago

Are there any steps to learn how to analyze the error items in the report

Do you mean how to figure out why test have failed?

For that I would say that you should first understand what the failing test is doing then pinpointing out the reasons for the failure based on that.

accept02.c:55: TBROK: setsockopt(7, 0, 42, 0xfff043cf78, 136) failed: ENODEV (19) failed: ENODEV (19)

What does this mean?I think he means there is no such device

SAFE_SETSOCKOPT(server_sockfd,SOL_IP,MCAST_JOIN_GROUP,mc_group,mc_group_len);

How to look to know what kind of device it is?

Looks like something is wrong with multicast on the machine, no idea why it does not work though, you have to figure that out yourself.

Also please stick to English.

Is it possible that my device does not support multicast
