Design Notes

Breakpoint Properties Dialog

The breakpoint properties dialog design directly affects three of the planned bugs:

  • bug 360291 - Allow user to edit line breakpoint file in properties dialog
  • bug 360295 - Customize property dialog for editing breakpoints
  • bug 360588 - Allow user to edit all its properties prior to creating the breakpoint [DONE]

The data flow in the breakpoint properties dialog is illustrated in the following diagram. Below it is a comparison diagram from the Wind River product. CDT Breakpoint Properties Dialog - Overview

Minutes

  • Mikhail demo a preliminary patch to demonstrate we could display target breakpoint nodes under the main platform breakpoint node.

    • This made us realize that showing all targets for each breakpoint ends up being pretty much showing the entire debug view tree under each breakpoint
    • Showing all targets is not a feasible solution
    • One alternative was to use the active contexts of the debug view to only show the corresponding targets under the breakpoints
    • More thought and discussion needed
  • Marc K demoed two versions of Mikhail's patch of usage of Breakpoint view detail pane

    • Alvaro's version allowed to edit some breakpoint properties directly
      • This can allow users to notice that they can perform certain actions on breakpoint like changing its type

CDT BreakpointDetailPane Solution2.png

  • Jonah demoed Mikhail's patch of using colour for breakpoint installation status
    • https://git.eclipse.org/r/25848
    • The breakpoint would always show in the breakpoint view and in the editor, but its colour would change based on the active debug context

  • Next call in a month to continue discussion

Actions

  • Everyone to think about ideas of what should be shown in the main breakpoints view
  • Everyone to think about ideas of what should be shown in the detail pane of the breakpoints view
  • Look into how other IDEs handle breakpoints to address such issues. List of other possible IDEs is at the bottom of this page.
  • Try to find a multicore platform that could be used to better understand use-cases for breakpoints

  3. Jonah Graham (Kichwa Coders)
  4. Marc Dumais (Ericsson)
  5. Marc Khouzam (Ericsson)

Minutes

  • Issues
    1. Hard for users to control where breakpoints are installed on multi-core systems
    2. Breakpoints don't work smoothly in a multi-session situation
  • High-level requirements
    1. Users have trouble seeing where a breakpoint actually applies (target, thread, core, etc)
    2. Users need a good way to control where a breakpoint should apply
    3. Need to persist user-configured applicability of breakpoints
    4. Need multiple breakpoints at the same location so as to configure each one differently
    5. Synchronization with the GDB console should work in all cases
  • Can we show columns in the breakpoints view?
  • Actions
    1. Mikhail to re-implement a prototype to show target breakpoint nodes under main platform breakpoint node
    2. Others to provide Mikhail with small list of expectations about what should be shown in the breakpoints view for his prototype
    3. Marc K or Alvaro to prepare demo of Mikhail's patch of usage of Breakpoint view detail pane
    4. Jonah to prepare demo of Mikhail's patch of using colour for breakpoint installation status
    5. Look into how other IDEs handle breakpoints to address such issues:
