RE: [cdt-debug-dev] Re: Debugging executables with no project

["Alexiev, Dobrin" <dalexiev@xxxxxx>]

Thanks Mikhail, 
I hope the next week I can pinpoint the changes needed in CDT to
accommodate the project-less and program-less debugging. 
Right now I have a CDI debugger that is not GDB with its own launch
configuration type.

Dobrin,

I'll try to answer to some of your questions. See my comments inline.

Indeed, in this case there is no need to have a project or an executable
for 
debugging, assuming you are attaching to a running process. The problem
is 
that currently the CDT debugger uses the executable to get the address 

factory. It is also used to create address breakpoints. Both problems
are 
solvable in the CDT frame. And I am definitely interested to make the
CDT 
debugger cleaner.

All manipulations with projects are done above the CDI level.
Executables 
are used to create sessions, but null can be passed to 
"createAttachSession".

Assuming the problems with address factories and address breakpoints are

fixed, I would prefer to have a special launch configuration type for
this 
type of debug sessions.
