[lldb-dev] LLDB-MI from Eclipse hangs

I wanted a log with Eclipse talking to lldb-mi to see if it was doing anything odd. It's not:
-exec-continue --thread-group i1
< 5> send packet: $c#63
-list-thread-groups i1
We have lldb-mi launch hexagon-sim automatically; it launches the same way debugserver does, with reverse-connect. I'd expect an -exec-run to do this automatically for you. No need to specify parameters to debugserver.
Here is some of a log of Eclipse talking to lldb-mi talking to a Hexagon target. It looks very similar, except for -exec-run instead of -target-select remote and -exec-continue:

Is this the GDB log while still running lldb-mi? I would like to see a log of any program that actually runs using "gdb" as the MI program. This will allow us to see a working example. We know it isn't working with LLDB and I was thinking we can get hints of what is expected with an actual GDB doing the MI.

What is the extra ":" before the address? debugserver doesn't support this syntax and that is why it is causing issues.

Eclipse called –list-thread-groups while the target was running, and it worked fine. This was with a 2 year old lldb-mi, but I’d expect a modern lldb-mi to work as well. The spec at https://sourceware.org/gdb/onlinedocs/gdb/Thread-groups.html talks about what this command does. It gives a list of process groups that the debugger is debugging, so it doesn’t matter if a certain process is running or not.

And then all the commands are executed by Eclipse automatically. I do not see two different steps as attach and continue. So I am not sure how to pass command "log enable gdb-remote packets". May be I am missing something. Can you please help me here, so that I can get the required log as suggested by you? Thanks.

Another thing to note: if you are remote debugging to a Mac from another machine and don't have any files cached (all shared libraries from the remote machine), they will be read from memory when the DynamicLoaderMachOSX figures out which shared libraries the process has. This might be slow and take quite a while and it might delay your debugging as you download a few hundred shared libraries for the first time. So you might see long delays as you debug. You might try and wait for a few minutes to see if the process stops correctly after reading everything from memory.
