Minutes
Things for Juno
- Marc was planning on working on Multiple selection https://bugs.eclipse.org/bugs/show_bug.cgi?id=330974
- Mikhail mentioned that the Selection policy may be a problem
- Platform may require changes for selection policy
- Already some selection policy problems are being seen
- A good selection policy is important for usability, so it is important for the multi-selection feature
- Debug testing for 4.2 ongoing.
- Things look good for Tracepoints and Pin&Clon (which were broken with earlier builds of 4.2)
- Reverse debugging buttons don't work properly with 4.2. Marc will report problems
- Jason will not be able to work on multicore at this time because Sage needs all-stop for multicore debug, but CDT is more focused on non-stop.o
- Trying to get all-stop to work nicely with multicore may be something Sage can look at
Things post-Juno (Kepler)
- Marc's current plans is to focus on adding features to the multicore visualizer
Architecture-specific visualization
- It was suggested that visualizations that are specific to different architectures (e.g., Tilera) could still be added to CDT.
- We can imagine having visualizations for many different architectures (Tilera, TI, Intel, etc)
- This would allow users that have multiple different architectures without need to change their tool for each one
- Visualization is not the only factor however; connection with the backend (e.g., using GDB) may not be the same as what is in CDT.

Minutes
Visualizer view
- Visualizer examples plugin was added to CDT with two examples
- Problems Visualizer
- SourceGraph Visualizer
- The examples show different ways on how to extend the Visualizer framework.
Enhanced breakpoints
- We see that Pawel is making good progress
Expressions view additions
- Pawel posted some comments/suggestions to the bug
Grouping
- Interest from Mentor, but nothing planned for the moment

- Bruce Griffith (Sage)

- Bill Swanson (Tilera)
- Randy Rohrbach (Windriver)
- Marc Khouzam (Ericsson)
Minutes
General
- Why not much focus on multi-vendor debug solution so that plugins from one vendor be used into another CDT installation?
- Probably not an interesting business case for vendors
- For others, they need to change the platform, so they can't work on someone else's IDE
- Marc will make time to review some contributions that are pending. Anyone else?
Visualizer view progress
- Bug 335027
- Feature has been contributed!
- Bill nominated as committer.
- New&Noteworthy http://wiki.eclipse.org/CDT/User/NewIn90#Multicore_Visualizer_View
- Multi-select feature would be very useful
Enhanced breakpoints
- Pawel and Randy are working on this. Progress going well both in Platform and CDT
- Ability to create a breakpoint and specify its attributes at creation time
- Allowing to add more complex preferences to breakpoints
- Must verify how Tracepoints will be impacted
Expressions view additions
- Contribution bug will be posted soon
Grouping
- No update

Minutes
Visualizer view progress
- Bug 335027
- More feature have been added: selection, synchronization with Debug View, toolbar, context menu
- Marc finishing some proposed refactoring before contribution is started
- CQ should be opened this week to contribute. Will go into master branch as an optional feature.
- Demo was given. Very cool!
- Wasted space in visualizer view. Can CPUs 'hug' Cores to avoid that waste? Cores should stay square.
- Need multi-selection run-control for visualizer Bug 330974. Marc will contact Dobrin to see if any progress was made.
- This could apply to target management to show what is running on the target. Would this be a second visualizer view for TM or a different visualizer in the same view? This brings up the nice applicability of Pin&Clone.
- Pin and clone would apply well to visualizer
- How do we show process info in visualizer?
- Process on cores don't really matter, what matters is what threads belong to the same process
- brightness can be used to show all threads in the same process as the one selected
Expressions view additions
- Enhancement to allow the expressions view to use Working Sets. The idea is to use Pin&Clone and Working sets to show only the expressions for a specific core (i.e. context)
- Demo
- Nice demo showing how working groups and pin&clone can be used to show a subset of expressions and pin them to a core
- Working groups have been added to DSF and allow to filter the expressions view
- Wizard was also added to create working groups and to easily pin them.
- Abeer will open a bugzilla to contribute this feature to CDT.
