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 (one can imagine a HTTP debugger, or even a silent debugger)
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).
- Is it okay to retrieve the whole application state through ABSTRACT_DEBUG_VALUE's? Seems to become really slow with big applications.
- Console debugger crashes (Arno can you provide details please)
- TTY debugger seems to have problems when exception in infix features occurs -> not possible to use tty menu anymore
- Sometimes combination of other tty functions (e.g. displaying all classes in system)
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)
- Console Menu (again Arno)
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.
- Prestate capturing
- How can we use the debugger for it
- old values
- invariants
- How can we use ES capture and "Review" for it?
- How can we use the debugger for it
- Prestate capturing
- 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?
