[lldb-dev] Failing LIT-based lldb-mi tests

[via lldb-dev]

Yes, the communications back and forth indicate that lldb-server is running and lldb-mi is connected to it.

 

My run was successful. You mentioned load on the machine; do you see any failed runs from lldb? Both lldb and lldb-mi make the same call (Target::Launch) to start the process.

 

My log looks like this:

the rest of the log is full of qRegisterInfo and other packets from a successful run.

Here is what I got from gdb-remote packet log:

lldb-mi          <  13> send packet: $qHostInfo#9b

lldb-mi          <  11> send packet: $qEcho:1#5b

Could somebody help me with understanding of what is happening here?

 

 

Just to clarify: Is this from a session that failed with the symptoms you described earlier?

I'm not familiar with the protocol, but the fact that there are send and read log entries makes it sound like the communication itself is working.
