Vadim Yanitskiy cb24ec5a2d Rename sedbgmux.py to sedbgmux-shell.py 2023-01-14 02:52:00 +06:00
Vadim Yanitskiy 569e5d3e9c SEDbgMuxApp: use cmd2.Fg instead of deprecated cmd2.fg 
In v2.3.0 both cmd2.{fg,bg} have been deprecated in favour of cmd2.{Fg,Bg}.
In v2.4.0 both cmd2.{fg,bg} have been removed.

See https://github.com/python-cmd2/cmd2/blob/master/CHANGELOG.md

Vadim Yanitskiy 530975eff2 SEDbgMuxApp: properly handle peer.recv() returning None 
In 2990cc14b8 I introduced a regression,
which affects the 'establish' command: if no data is received from a
Data Provider during 500 ms, the application crashes:

    File "sedbgmux.py", line 151, in do_establish
      if f['MsgType'] != DbgMuxFrame.MsgType.ConnData:
  TypeError: 'NoneType' object is not subscriptable

This is happening because peer.recv() is returning None.

Vadim Yanitskiy 2990cc14b8 SEDbgMuxApp: use non-zero default serial port read timeout 
This is required for a follow-up change moving DebugMux I/O handling
into separate threads.  We need to be able to stop a thread, which
is executing blocking self.io.read() call.

Vadim Yanitskiy e09c227661 SEDbgMuxApp: handle ConnEstablished with DPRef=0xffff 
This format string found in firmware image of a modem:

  DebugMux[DL,HandleConnectReq] Could not find DPRef 0x%04X;
                                sending Connect Response with ConnRef=0xFFFF

gives us a hint on what happens when ConnEstablish message contains
an unknown DPRef that was not announced or has became inactive.
