Re: GDB Python - gdb.execute() - with a timeout?

Thanks for the example but that won’t work for my situation - solution needs to run from within a GUI that has already wrapped GDB/LLDB in some form (for example eclipse). The pexpect solution - is external and controls GDB, in my scenario something else is already controlling GDB (i.e.: Eclipse or Emacs-GUD mode)

I have an idea - but don’t know how to implement parts of it
	After (X) timeout period I need to simulate pressing “control-C” via the gdb_python solution.

The idea is that Control_C at the GDB command console will cause GDB “cont” to stop - and send a “target halt” command and thus the gdb.excute(‘cont’) call will finish & return.

That would probably be sufficient for my purposes, the idea is sort of this:

Mainline thread:
    Set global “timeout period”
    FORK - creating new “timeout thread”
    perform  gdb.execute(“cont”)
    *CANCEL* the timeout thread.

Meanwhile,  timeout thread
     sleeps for “timeout period”
     After timeout period - ?? somehow ?? Simulate human pressing Control-C at the GDB console window

Some notes:
   (A) I know that GDB is single threaded
   (B) I know there is an ‘event queue’ or ‘work queue’
   (C) As I understand Python threads must “post” an event to a GDB event/work queue
   (D) Eventually when GDB is ‘safe’ that work item would be executed.

Assuming that work item is a call to a Python function, I don’t see how via Python the way to simulate “control-C” at the command console. 

Am I missing something?  Any suggestions?

Thanks.
