Subject: ANNOUNCEMENT: JDEbug Project Gets Underway
I have some wonderful news to announce. Sun Microsystems has hired a
summer
intern, Amit Kumar, to develop a debugger for the JDE.
Excellent
* The JDE will drive the debugging session by issuing commands using
a
command language that we will design. Debugger responses will be
Lisp
expressions to avoid the need for a specialized parser.
Where practical, I'd like to see command language similar to the existing
jdb, just to make using it easier.
* The debugger will support setting breakpoints by line within a
source file
or method within a class.
Being able to set breakpoints that are only active within a particular
thread or a particular instance of an object would also be useful
* A goal is to implement automatic display of in-scope variable
values in
the debugger
My concern with this is that if I have a large number of objects in scope it
may be slow. I'd like this to be an optional window I can display.
* Navigating up and down stack frames will be supported. We need
guidance
on how this feature should work.
Up and down commands. A buffer that can display the current position in the
stack. Being able to click on the stack display to move up and down the
stack would be nice. Automatically modify the display of in-scope variables.
* Support for debugging multithreaded applications is a design goal.
We
need input on what features are useful for this purpose.
For me this is a prerequisite and, as time is short, it should come before
such things as the persistent breakpoints and in-scope variable display.
Two other things I'd like to see are:
Expression evaluation, including calling Java functions
Some sort of configuration so that when I do a step-into it still steps over
certain package, eg it doesn't normally step into java.lang packages.
