* EclipseCon and CDT Summit
 
** Please update Summit
 
* Planned for Kepler release
 
** StepIntoSelection [https://bugs.eclipse.org/244865 Bug 244865]
 
** Dynamic-printf [https://bugs.eclipse.org/400628 Bug 400628]
 
** Multicore Visualizer filtering of cores/CPUs to reduce amount of visible information
 
* Pin&Clone in platform [https://bugs.eclipse.org/145635 Bug 145635]
 
** No longer planned for Kepler
 
* Expression working sets [https://bugs.eclipse.org/372181 372181]
 
** Pawel re-factored patch
 
** After review there were many comments from platform that is delaying adoption
 
** People interested must answer comments to try to move this forward
 
** Can enhanced expressions be used for these use cases?
 
*** Abeer will follow-up on this with his product people.
 
*** Marc to look at Pawel's CDT fix for expression working sets to try it with Enhanced Expressions.  Persistence of the collapsed state should work with this patch.
 
* Step into Selection [https://bugs.eclipse.org/244865 Bug 244865]
 
** Alvaro is implementing this feature
 
** First version will deal with the most common and simplest cases
 
* Dynamic-printf [https://bugs.eclipse.org/400628 Bug 400628]
 
**  Support for "Add breakpoint..." command for dprintf.  First step is to support if for tracepoints [https://bugs.eclipse.org/376116 Bug 376116]
 
* Hardware breakpoints [https://bugs.eclipse.org/332993 Bug 332993]
 
** We mentioned we could use a breakpoint type for hardware breakpoint and temporary bp
 
** We could do the same for Tracepoints, but since tracepoints are a top-level breakpoint and not an attribute of a C/C++ breakpoint, this would need a lot of work.  Also, the property page for tracepoint is different because it has a passcount and no ignore count.
 
** How should dynamic printf be implemented?  As a top-level bp like tracepoints, or as an attribute of breakpoints?  For reference, WindRiver had their implementation use a top-level breakpoint.
 
** GDB has a setting to tell GDB to set a hardware breakpoint if it can and if not then set a software breakpoint.  This should be considered when dealing with hardware breakpoint support

=== Minutes ===
 
* 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.
 
* Pin&Clone in platform [https://bugs.eclipse.org/145635 Bug 145635]
 
** Pawel will continue working on it
 
** Plan is to make Pin&Clone a single action
 
** Would be nice if people gave feeback on the branch which has this new way of handling things
 
* Extend CDT launch to allow external profiling [https://bugs.eclipse.org/391608 Bug 391608]
 
** All changes will be made in Linux Tools project, no need to change CDT
 
* CPU usage shown in Multicore Visualizer [https://bugs.eclipse.org/396268 Bug 396268]
 
* GDB Console synchronization
 
** Memory changes synched with CDT [https://bugs.eclipse.org/397715 Bug 397715]
 
** Reverse debugging enabled synched with CDT [https://bugs.eclipse.org/399163 Bug 399163]
 
** Other new notifications planned such as: =traceframe-changed
 
* Expression working sets [https://bugs.eclipse.org/372181 372181]
 
** Pawel put Abeer's patch and put it on a branch with a bit of refactoring.
 
** Pawel is playing around with automatic selection of working sets
 
** If Pawel does not have enough time to continue playing around with it he will commit the feature as Abeer implemented it
 
** Automatic selection would be nice and Abeer is also looking into it
 
** Abeer will continue to work on it and post information on the bug
 
* StepIntoSelection is being implemented for CDT [https://bugs.eclipse.org/244865 Bug 244865]
 
* 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

* 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
