* A extra conference call will be scheduled February 19th to discuss features for the Multicore Visualizer.  All are welcomed to call in.  Info will be posted on the list.
+
* Summary of CDT Summit/CDT Day/EclipseCon
* Pin&Clone in platform [https://bugs.eclipse.org/145635 Bug 145635]
+
** Java 8
** Pawel will continue working on it
+
** do we do it on master, it will break java 7, it should be done on the 9_0 branch
** Plan is to make Pin&Clone a single action
+
** email to the list
** Would be nice if people gave feeback on the branch which has this new way of handling things
+
* cdt 9.0 for Mars+1 release (June 2016)
* Extend CDT launch to allow external profiling [https://bugs.eclipse.org/391608 Bug 391608]
+
** 9_0 branch where API breaking changes are allowed
** All changes will be made in Linux Tools project, no need to change CDT
+
* Doug plans to split out native plugins into their own git repo and build them separately to provide them to others that should not depend on CDT  
* CPU usage shown in Multicore Visualizer [https://bugs.eclipse.org/396268 Bug 396268]
+
* CDT 8.7 plans
* GDB Console synchronization
+
** Grouping feature to support
** Memory changes synched with CDT [https://bugs.eclipse.org/397715 Bug 397715]
+
*** Marc K has started looking at this again, based on the work from TI
** Reverse debugging enabled synched with CDT [https://bugs.eclipse.org/399163 Bug 399163]
+
** Memory view fixes/improvements
** Other new notifications planned such as: =traceframe-changed
+
*** Alvaro working on this
* Expression working sets [https://bugs.eclipse.org/372181 372181]
+
** VarObjects for Registers would be interesting.
** Pawel put Abeer's patch and put it on a branch with a bit of refactoring.
+
*** Currently we assume every register is under a group, but it may not be the right thing to do
** Pawel is playing around with automatic selection of working sets
+
* Enhancement bug written to LaunchBar allowing to handle multiple launches/launch group http://eclip.se/462372
** If Pawel does not have enough time to continue playing around with it he will commit the feature as Abeer implemented it
+
** Mikhail has a patch that removes some duplications in the debug view in the case of the launch group
** Automatic selection would be nice and Abeer is also looking into it
+
* Patches needing review
** Abeer will continue to work on it and post information on the bug
+
** A couple of breakpoint patches from Mikhail
* StepIntoSelection is being implemented for CDT [https://bugs.eclipse.org/244865 Bug 244865]
+
** William submitted a patch for managed build, will email the list to get noticed
* Marc K would like to try to add Dynamic printf to CDT
+
** Breakpoint types would be used to provide this
+
** The new bp type would be kept in DSF-GDB
+
* Hardware breakpoint contribution [https://bugs.eclipse.org/332993 Bug 332993]
+
** Mikhail is concerned that changing the breakpoint type to set a hardware bp is overkill
+
** Another option would be to add a "Toggle Hardware Breakpoint" command, although that is not ideal either
+
** We would like to provide this feature in CDT, and Mikhail might be able to post a patch

 +
** Planning continues.  10 attendees have signed up so far.  Based on last year, we expect more though
 +
* CDT 8.6 release
 +
** [https://wiki.eclipse.org/CDT/Manual_Testing Joint testing] to be done
 +
** We hope to have it done by the end of this week
 +
** Everything is on track for the release
 +
* Next CDT release to be 8.7
 +
** Less than two months left until API freeze for Mars, and it does not seem anyone has plans or needs to break the API
 +
** Doug [https://dev.eclipse.org/mhonarc/lists/cdt-dev/msg28861.html posted to the list] to see if there was any concerns about that
 +
* CDT for Mars
 +
** work continues for o.e.remote
 +
** LaunchBar is being updated to follow o.e.remote new APIs
 +
** Autotools will need to be updated as well
 +
** Still planning on removing CDT's dependency to RSE for Mars (Remote Debug launch)
 +
** Connections should not be part of launch configuration as connections are user-specific.  Instead using an OSGI service will be better.
 +
* FindBugs
 +
** Marc to post a patch to enable running FindBugs and PMD as a build profile.
 +
** We can have the nightly build use that profile and see if that proves valuable.
 +
** This will increase the build by about 20 minutes but provide valuable feedback
 +
** The verify job will not run FindBugs
 +
* Visual Studio support contribution
 +
** [https://dev.eclipse.org/mhonarc/lists/cdt-dev/msg28851.html Guy B offered to contribute] a Visual Studio integration to CDT
 +
** Sounds like it can be interesting to some.
 +
** Guy was asked to open a bug to discuss the contribution process

* Assembly view vs Disassembly view
+
* CDT Summit/CDT Day
** Want to show assembly with source code without the use of the Debugger
+
** CDT Summit wiki.  Please sign up.
** How does CDT get access to the assembly code
+
** CDT Day planned. 7 talks on different topics related to CDT
** A dummy debug session hidden from the user can be used to fill the disassembly view
+
* CDT 8.6 anything missing?
** Jeff will open bug
+
** Nothing major planned for the last week
* Pin&Clone in platform [https://bugs.eclipse.org/145635 Bug 145635]
+
* Register grouping committed. https://wiki.eclipse.org/CDT/User/NewIn86#Register_grouping
** Update for CDT to remove Pin&Clone buttons: [https://bugs.eclipse.org/398012 Bug 398012]
+
** VarObjects for Registers would be interesting.
** Terminate and restart should keep the Pin&Clone with this CDT patch
+
** If time allows, Mikhail may have a look again.
** Feature can be tested in a branch in the platform repo
+
* All Debug JUnit tests running on HIPP using all of GDB >= 7.1
** Would allow to use another 'agent' to provide info without a debugger
+
** Local tests all pass: https://hudson.eclipse.org/cdt/job/debug-tests-master-all-gdb-versions/
** Adds breadcrumb to the view when pinned
+
** Remote tests down to 7 failures: https://hudson.eclipse.org/cdt/job/debug-remote-tests-master-all-gdb-versions/
** No colors and no visual decorator in the Debug view, as CDT used to do
+
* Older GDB support
* Extend CDT launch to allow external profiling [https://bugs.eclipse.org/391608 Bug 391608]
+
** In some cases, probably with more recent GCCs, GDB 7.0 cannot step over printf (and maybe other issues)
** To see profiling buttons one must Customize Perspective and enable the "Profile" menu
+
** We discussed and approved only supporting GDB 7.1 and higher
** Profile configuration add a single Profile tab which give the user the possibility to choose between different available profile.
+
** We won't remove the code supporting older GDBs but we won't work on making those work
** Profile As... will now only show "Local C/C++ Application" and will default to the highest ranked available profiler
+
** We will announce in N&N and make it part of the 8.6 review record
** If no profiler is installed the profiling launch will show an error.
+
* SWTBot testing for Debug/CDT https://git.eclipse.org/r/#/c/35988/
* CPU usage shown in Multicore Visualizer [https://bugs.eclipse.org/396268 Bug 396268]
+
** Proof of concept that provides one test.
** Good progress, expect to push code next week
+
** Marc K to review and commit very soon to get the infrastructure in
* Expression working sets [https://bugs.eclipse.org/372181 372181]
+
* LaunchBar will be part of Mars
** Abeer will comment on bug
+
** Doug will work on a CDT remote launch using o.e.remote
** Pawel will look at it once Pin&clone is ok
+
** Doug got request to have a UI for multiple launches working with the launch bar
* GDB Console synchronization
+
* Launch UI
** Mikhail did the synchronization of breakpoints.  This needs GDB 7.4
+
** Mikhail has started work on it again
** GDB 7.6 will provide new MI notifications when data changes.
+
** Marc K has pushed a feature for review, which uses the new =memory-changed event [https://bugs.eclipse.org/397715 Bug 397715]
+
** Marc K plans on making use of other new notifications such as: =traceframe-changed, =record-started, =record-stopped
+
