<br>
I've got some preliminary but functioning work in place in order to support<br>
self-debugging. Immediately forthcoming is two patches, summarized below, which<br>
implement basic support for self-debugging on Linux. I've leveraged the<br>
ProcessMonitor architecture on Linux in order to do this, so the first patch is<br>
a refactor of ProcessMonitor to allow me to create a different implementation of<br>
it. The second patch actually fills in the self-debugging implementation.<br>
<br>
[PATCH 1/2] Refactor ProcessMonitor into an abstract base class.<br>
[PATCH 2/2] Support debugging yourself on Linux.<br>
<br>
There's still some issues:<br>
* I needed to disable JITLoaderGDB [1] in order to prevent lldb from attempting<br>
to set a breakpoint at attach. I'm also not clear on what JITLoaderGDB does<br>
even after perusing the code, so I'm not sure if disabling it is the right<br>
thing to do.<br>
* I needed to disable LLDB copying it's stdin to it's inferior's [1] as it<br>
would result in multiple threads reading from stdin - making it impossible to<br>
use the prompt. This behavior makes sense to me if the debugee is launched<br>
from LLDB, but I'm not clear on why LLDB attempts to do it when you've<br>
attached to your debugee.<br>
* "thread list" returns nothing. I think there's a larger problem here. Needs<br>
investigation.<br>
<br>
Thanks,<br>
