            Bug ID: 24384
           Summary: Python API: Connecting to remote server leaves the
                    process in unloaded state
           Product: lldb
           Version: 3.7
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs

Tested using the svn revision 244212 (3.8.0).
Everything works fine in lldb's CLI. The issue is only with the Python API.
After getting connected, the process is left in "unloaded" state.
The same thing happened with the stable 3.6.2 release too.

=== server output ===

$ lldb-server g :1234 target/debug/des
using the default platform: host
Launched 'target/debug/des' as process 22203...
lldb-server-local_buildListening to port 1234 for a connection from
localhost...
Connection established.

=== python try 1 ===

>>> import lldb
>>> d = lldb.SBDebugger.Create()
>>> t = d.CreateTargetWithFileAndArch(None, None)
>>> l = lldb.SBListener()
>>> e = lldb.SBError()
>>> p = t.ConnectRemote(l, "connect://localhost:1234", None, e)
>>> s = lldb.SBStream()
>>> p.GetDescription(s)
True
>>> print s.GetData()
SBProcess: pid = 22203, state = unloaded, threads = 1, executable = des

=== try 2: using command interpretter ===

>>> import lldb
>>> d = lldb.SBDebugger.Create()
>>> ci = d.GetCommandInterpreter()
>>> cro = lldb.SBCommandReturnObject()
>>> ci.HandleCommand('gdb-remote 1234', cro)
1
>>> ci.HandleCommand('process status', cro)
1
>>> print cro.GetOutput()
Process 16338 unloaded
* thread #1: tid = 16338, 0x00007f6764d99d80, name = 'des', stop reason =
signal SIGSTOP
    frame #0: 0x00007f6764d99d80
->  0x7f6764d99d80: movq   %rsp, %rdi
    0x7f6764d99d83: callq  0x7f6764d9db10
    0x7f6764d99d88: movq   %rax, %r12
    0x7f6764d99d8b: movl   0x220ec7(%rip), %eax

>>> ci.HandleCommand('process continue', cro)
6
>>> print cro.GetError()
error: Process must be launched.

>>> ci.HandleCommand('process launch', cro)
There is a running process, kill it and restart?: [Y/n] n
