Please complete the following list with your items:

• General dicussion about the CDD idea
  • Where should it go?
  • What are the biggest obstacles?
  • CDD debuggers needs
    • How to best do fg debuging of test cases
    • How to best do bg extraction of test cases
      • Is our approach of using the debugger in console mode the right one?

Jocelyn: For now, there is GUI debugger, TTY debugger, and I guess CDD debugger, but you are not obliged to be in "console" mode
Andreas: The CDD test case extractor must be given an extractor (it doesn't care whether it gets the gui one or the console one). We would also like to know whether how we use the interface is correct?
one can imagine a HTTP debugger, or even a silent debugger

• • • Console debugger crashes (Arno can you provide details please)

Jocelyn: TTY debugger is not perfect (not enough time to work on it), what should be done is
1) change the "menu like control" by a "shell like control"
2) having the debugger controller in a separate thread, this way we could support "interrupt" and so on
3) ... many improvement, and support all the debugger functionality

• ok, then do it :-). No, seriously, the question is if and how we can improve the tty debugger just to enable system level tests for our cdd
  • Console Menu (again Arno)
    • Multiple debuggers at the same time (large long term issue)

Jocelyn: That might be possible, but this won't be that easy for now, however, I have been changing progressively the design to be more flexible, and to allow that in the future. Maybe ISE could plan this for 6.3 with other major design changes.

• • Build system needs
    • How to do it properly on Windows? (Stefan, please provide details here)
    • (by Stefan) well, i am getting used to it. The problems with the updated build scripts is that they might not be compatible with 6.0, which cdd is based on? (i admit i did not try)

Jocelyn: Those days, I am integrating+updating works from es-make team (Bernd and others) into the trunk, this way it should be much more easier to build the EiffelStudio tools. Still in progress.

• • Guided tour through debugger
  • Guided tour through build system
  • Unable to debug ES with ES (only Stefan and Andreas). Maybe Jocelyn can have a quick look.
  • Capture and Replay
    • Compare ES Capture and Replay and Sel. Capture and Replay

Jocelyn: ES provides "Execution Recording and Replay", or should I say "Review"

• • • What are strengths and weaknesses?
    • Can approaches be combined for mutal benefit?
    • Where to go from here?
