[lldb-dev] LLDB-MI from Eclipse hangs

From the sample I see that LLDB is in synchronous mode. It was caused by:

> 313,449 12-gdb-set target-async off
> 313,453 12^done

This sets LLDB into synchronous mode where if you say "-exec-continue", that command won't return until the target stops. This causes lldb-mi to not process any commands until your process stops or exits. Not sure that this is what we want. We can see the handler for "target-async" below:

//++ ------------------------------------------------------------------------------------
// Details: Carry out work to complete the GDB set option 'target-async' to prepare
//          and send back information asked for.
// Type:    Method.
// Args:    vrWords - (R) List of additional parameters used by this option.
// Return:  MIstatus::success - Function succeeded.
//          MIstatus::failure - Function failed.
// Throws:  None.
//--
bool
CMICmdCmdGdbSet::OptionFnTargetAsync(const CMIUtilString::VecString_t &vrWords)
{
    bool bAsyncMode = false;
    bool bOk = true;

    if (vrWords.size() > 1)
        // Too many arguments.
        bOk = false;
    else if (vrWords.size() == 0)
        // If no arguments, default is "on".
        bAsyncMode = true;
    else if (CMIUtilString::Compare(vrWords[0], "on"))
        bAsyncMode = true;
    else if (CMIUtilString::Compare(vrWords[0], "off"))
        bAsyncMode = false;
    else
        // Unrecognized argument.
        bOk = false;

    if (!bOk)
    {
        // Report error.
        m_bGbbOptionFnHasError = true;
        m_strGdbOptionFnError = MIRSRC(IDS_CMD_ERR_GDBSET_OPT_TARGETASYNC);
        return MIstatus::failure;
    }

    // Turn async mode on/off.
    CMICmnLLDBDebugSessionInfo &rSessionInfo(CMICmnLLDBDebugSessionInfo::Instance());
    rSessionInfo.GetDebugger().SetAsync(bAsyncMode);

    return MIstatus::success;
}

So we see that it sets the debugger into synchronous mode. I don't know MI well enough to know if this is desired, but seeing that eclipse quickly follows up the -exec-continue with a -list-thread-groups, I am guessing this isn't what we want. I would be interested to see the MI log from a GDB that actually works to see what the packet responses are expected to look like.
