 +
** Clone in 8.5, Pin in 8.6.  Together allows to have multiple visualizer views and pin each one to a different debug session
 +
** Can also have multiple visualizer views using different filter levels
 +
* Launch bar
 +
** Does it support Profiling?  Does not look like it but does seem to be a good fit.
 +
** Should it be part of the Standalone debugger?  Something to think about.
 +
* [http://eclip.se/235747 Register grouping]
 +
** Review continues and we aim for 8.6
 +
* [http://eclip.se/439624 Per-element formatting for expressions and variables]
 +
** Aiming for 8.6 and working out the last one or two remaining issues
 +
* Example plugin showing how to extend DSF-GDB http://eclip.se/441277
 +
** Posted on Gerrit https://git.eclipse.org/r/#/c/30660/
 +
** Marc will continue working on it and may ask people with experience extending it to provide some of their experiences
 +
* New UI
 +
** Vladimir was going to post to Github and willing to post elsewhere if we wanted.
 +
** Marc will ping him
 +
* Stand-alone debugger SWTBot tests
 +
** Jeff wants to have to SWTBot tests for the Stand-alone debugger
 +
** We are interested in getting those into CDT
 +
** Marc-Andre will help configure our HIPP to get it running
 +
** Jeff will post patch to re-enable autotools SWTBot tests as a first attempt
 +
* What is the state of lldb MI and working with CDT?
 +
** Recommendation is to post questions to the list and see
 +
** Could the stand-alone debugger also work for lldb?  It should be easy once CDT support lldb.
 +
* Should we put effort in supporting Multiple versions of stand-alone debugger for a user?
 +
** The idea is that if a user has more than one version of CDT installed, only one stand-alone debugger will be setup and it will be the last one the user ran the install script for.
 +
** The user could copy the stand-alone debugger directory to allow to run more than one version
 +
** the user could also run the install script for the version she wants as a way to choose the version
 +
** We probably don't need to address this until there is an explicit request for such support

* CDT 8.5 (Luna SR1)
 +
RC1+1 Aug 18th 2014 Proposed feature freeze and branch point
 +
RC2+1 Sept 1st 2014 Proposed joint test effort
 +
RC3+1 Sept 8th 2014
 +
RC4+1 Sept 15th 2014
 +
Release Sept 26th 2014
 +
* Content will be small but that is expected as SR1 has barely 2 months of development time.
 +
* Marc K will email the list to propose the above release process: see email [https://dev.eclipse.org/mhonarc/lists/cdt-dev/msg28003.html here]
 +
* CDT 8.6 (Luna SR2)
 +
RC1+1 Jan 19th 2015
 +
RC2+1 Feb 2nd 2015
 +
RC3+1 Feb 9th 2105
 +
RC4+1 Feb 16th 2015
 +
Release Feb 27th 2015
 +
* CDT Logo: Plan is to use http://99designs.ca/ or https://www.designonclick.com/. Doug will take care of it and the Eclipse Foundation will finance it.
 +
* Using target definitions does not always refresh.
 +
** Target definitions were updated recently to include mockito but it does not seem to work.
 +
** There is a bug in PDE that does not refresh the target def properly.
 +
** Workaround is to open the target def file in an editor and change its version at the top then save.  Once refreshed, the version can be reverted.
 +
* How should target defs be updated?
 +
** How to use the 'staging' target def vs the others?
  
−
* Plans for Luna
+
* New UI
−
** New Launch UI
+
** Progress seems to have stopped. Priorities might have shifted at Mentor.
−
*** Vladimir is working on this
+
** Why not post the existing code in the hopes it could progress through other community members?
−
** Register groups [https://bugs.eclipse.org/235747 Bug 235747]
+
* [http://eclip.se/235747 Register grouping]
−
*** Alvaro posted to Gerrit for review
+
** Next round of review completed
−
*** Behavior very similar to CDI
+
** Targetted for CDT 8.6
−
** Multicore Visualizer with all-stop mode
+
* [http://eclip.se/439624 Per-element formatting for expressions and variables]
−
*** Marc D pushed a fix to Gerrit for review
+
** Feature is ready to be committed except for the refreshing issue when dealing with multiple sessions
−
*** Better support is now possible with all-stop thanks to the fact the Multicore Visualizer does not rebuild the model all the time
+
** Improvements mentioned by Mikhail (Marc K will open a bug: [http://eclip.se/441276 Bug 441276]):
−
** Dynamic-printf [https://bugs.eclipse.org/400628 Bug 400628]
+
*** Setting format should affect all children, probably not for complex structs but would be great for arrays
−
*** Much progress made by GDB
+
*** Should persistence be per-launch?
−
*** CDT will support starting with GDB 7.7
+
*** As was first experienced with CDI, some case for this feature are quite complicated.  We propose to implement feature in a reasonable way so as to add value, but not to necessarily address each corner case; as long as it does not break normal behavior.
−
** Tracepoint enhancement new patch pushed to Gerrit [https://bugs.eclipse.org/390827 Bug 390827]
+
* Example plugin showing how to extend DSF-GDB
−
*** Needs review
+
** DSF-GDB was originally meant to be and example of how to use DSF.  It has grown to be extended itself but does not provide an example of how to extend it.
−
** Advertising features (see the CDT Summit 2013 minutes [http://wiki.eclipse.org/CDT/summitecon2013#Minutes here]
+
** Marc K will open a bug to track progress, suggestions and discussions: [http://eclip.se/441277 Bug 441277]
−
*** No progress
+
** How to extend the view model elegantly?  Does not seem to be a good way.  Currently requires a lot of code duplication.  We would like to improve that.
−
** Enhanced Expressions enhancements
+
* Suggestion to support a Snapshot feature ''a la'' EDC.
−
*** No progress
+
** Idea would be to be able to save a snapshot during a debug session and send it to someone else to examine.
−
** Showing exited processes [https://bugs.eclipse.org/407340 Bug 407340]
+
** Could be implemented relatively easily using core files as snapshots
−
*** Tricky to support for older GDB versions.  May only support for newer versions, maybe starting with 7.3

−
* Kepler release
+
* Luna release
−
** We should do a wiki page about testing for the release
+
** Coordinated testing was valuable and helped find bugs that would have gone unnoticed
−
* Step into Selection [https://bugs.eclipse.org/244865 Bug 244865]
+
** Coordinated testing only required 1 to 2 hours of the involved people. Good return on investment
−
** Need to try with scalability feature of CDT.
+
−
* Multicore Visualizer filtering
+
−
** Allows to limit amount of visible data
+
−
** Can be foundation for a pin & clone type of feature
+
−

== April 9th, 2013 ==
+
* Launch bar
 +
** No update
  
−
Minutes of this meeting were lost.  Apologies for that.
+
* Debug tests on Hudson
 +
** Debug tests with latest GDB run as part of CDT's master nightly build and part of every Gerrit review build
 +
** Nighlty jobs added to run tests with GDB version 6.6 to latest.  Not all tests pass yet and should be eventually cleaned up or some disabled to get a green light
 +
** Nightly job to run tests using GDB built from its own master branch and another for GDB's maintenance branch.  This allows us to notify the GDB community of regressions that affect CDT before the GDB is released.
  
−
== March 12th, 2013 ==
+
* New UI
 +
** No update
 +
 
 +
* Multi-terminate/disconnect
 +
** Elegant solution posted and reviewed
 +
** JUnit tests are harder to write because we have to somehow check that we disconnected or terminated processes
 +
** Manual tests could be added instead in the test document
 +
 
 +
* Pin & Clone for Visualizer
 +
** Patch available to add a clone button to visualizer.  Waiting for review.
 +
** Will allow to have multiple visualizer views which work with different filters
 +
** Pin will be worked on to provide even better value for multiple visualizer views
 +
 
 +
* Stand-alone
 +
** -help now supported
 +
** params after executable are no longer swallowed by eclipse
 +
** vmargs now supported
 +
** better path support for binary including support for PATH variable
 +
** man page to be available
 +
** handling installations that use dropins, don't mix RPM install with p2 install

* EclipseCon and CDT Summit
+
* Luna release
−
** Please update Summit
+
** Would be nice to provide coordinated testing
−
* Planned for Kepler release
+
** Let's revive the test wiki page and get people to take parts of it.  Should be small effort per person but valuable overall
−
** StepIntoSelection [https://bugs.eclipse.org/244865 Bug 244865]
+
** Start with Debug and hope to show by example for other CDT components
−
** Dynamic-printf [https://bugs.eclipse.org/400628 Bug 400628]
+
* Dynamic printf [http://eclip.se/400628 Bug 400628]
−
** Multicore Visualizer filtering of cores/CPUs to reduce amount of visible information
+
** Committed to M7 for Luna
−
* Pin&Clone in platform [https://bugs.eclipse.org/145635 Bug 145635]
+
* [https://wiki.eclipse.org/CDT/StandaloneDebugger Stand-alone debugger]
−
** No longer planned for Kepler
+
** Commmitted to M7 for Luna
−
* Expression working sets [https://bugs.eclipse.org/372181 372181]
+
** New plugin
−
** Pawel re-factored patch
+
** First install CDT CPP then run o.e.cdt.debug.application/install.sh script
−
** After review there were many comments from platform that is delaying adoption
+
** Jeff will update N&N
−
** People interested must answer comments to try to move this forward
+
** Instructions [https://wiki.eclipse.org/CDT/StandaloneDebugger here]
−
** Can enhanced expressions be used for these use cases?
+
* New Launch UI
−
*** Abeer will follow-up on this with his product people.
+
** No specific update but work seems to continue
−
*** 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.
+
* Doug added Multicore Visualizer to Luna aggregated update site which will make it easier to install
−
* Step into Selection [https://bugs.eclipse.org/244865 Bug 244865]  
+
* Register grouping [http://eclip.se/235747 Bug 235747]
−
** Alvaro is implementing this feature
+
** Marc caused delay in review but should get to it in the next couple of weeks
−
** First version will deal with the most common and simplest cases
+
* Better disconnect feature which allows to disconnect from all processes
−
* Dynamic-printf [https://bugs.eclipse.org/400628 Bug 400628]
+
** Posted for review
−
** Support for "Add breakpoint..." command for dprintf.  First step is to support if for tracepoints [https://bugs.eclipse.org/376116 Bug 376116]
+
** Supports multiple selection
−
* Hardware breakpoints [https://bugs.eclipse.org/332993 Bug 332993]
+
* Feature to update bp icon in the editor based on installation state of the selection
−
** We mentioned we could use a breakpoint type for hardware breakpoint and temporary bp
+
** Posted for review
−
** 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

+
*** Too tight for Luna.  Aiming to have it available soon and have a longer soak time towards the release after Luna, in September
−

−
** Pawel put Abeer's patch and put it on a branch with a bit of refactoring.
+
*** If review goes well, could make it for Luna
−
** Pawel is playing around with automatic selection of working sets
+
** Stand-alone debugger

+
−
** 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

*CDT Summit/EclipseCon
 +
* Ongoing work
 +
** New Launch UI
 +
*** Working solution available!
 +
*** Ready to discuss some implementation detail
 +
*** Specific to CDT at the moment but could be generalized
 +
*** Main advantage is the support for multi-process
 +
** Trace Control Enhancements [https://bugs.eclipse.org/390827 Bug 390827]
 +
*** Feature committed! See [https://wiki.eclipse.org/CDT/User/NewIn84#Trace_Control_view_enhancements New and Noteworthy] for details.
 +
*** It would be nice to move some of the new widgets to a common area such as o.e.cdt.debug.ui
 +
*** Was not tested on Windows.  If someone can try it and report, that would be useful
 +
** Setting Hardware Breakpoint from the UI [http://eclip.se/332993 Bug 332993]

*** new bug opened to allow to change bp type at creation or after (based on Mikhail's work) [http://eclip.se/427898 Bug 427898]
 +
*** patch posted in bugzilla but will be posted to Gerrit
 +
*** do we need the first proposal too?  It's value is to set a default type.  Let's focus on first contribution and then discuss the original one.
 +
** Show values returned from function calls [http://eclip.se/341731 Bug 341731]
 +
*** Reviewed by Marc-Andre and updated accordingly
 +
** Dynamic Printf [https://eclip.se/400268 Bug 400268]
 +
*** Planned for Luna.
 +
*** GDB 7.7 much more stable.  Still some issue but not blocking
 +
*** Will be demoed at CDT Summit
 +
*** Patch is large but mostly a copy of Tracepoints.  Important changes are much smaller.
 +
** Multicore Visualizer with Parallella
 +
*** gdb stub for Parallella is being updated to provide CDT with the necessary information
 +
*** Will be demoed at EclipseCon
 +
** Stand-alone CDT debugger
 +
*** Customize perspective support added (needed for Reverse Debug and Tracepoints)
 +
*** Documentation has been updated
 +
*** Will be demoed at CDT Summit

*** Some limitations due to TM/RSE that we will have to deal with
−
** To see profiling buttons one must Customize Perspective and enable the "Profile" menu
+
** Trace Control Enhancements [https://bugs.eclipse.org/390827 Bug 390827]
−

+
*** Marc K has tried it out.  Looks great but a couple of comments communicated to Jeff
−
** GDB 7.6 will provide new MI notifications when data changes.
+
*** Start script will be simplified
−
** 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
+
*** Will be shown at the CDT Summit
 +
*** Some flags will be added to the command-line to specify launch option
 +
*** No need to create a project or a launch config.
 +

Multicore Debug Workgroup Minutes of Meetings

Sept 9th, 2014

Attendees

  1. Phil Mason (Broadcom)
  2. Alvaro Sanchez-Leon (Ericsson)
  3. Marc-Andre Laperle (Ericsson)
  4. Marc Dumais (Ericsson)
  5. Jeff Johnston (RedHat)
  6. William Riley (Renesas)
  7. Marc Khouzam (Ericsson)

Minutes

  • Multicore Visualizer Pin&Clone
    • Clone in 8.5, Pin in 8.6. Together allows to have multiple visualizer views and pin each one to a different debug session
    • Can also have multiple visualizer views using different filter levels
  • Launch bar
    • Does it support Profiling? Does not look like it but does seem to be a good fit.
    • Should it be part of the Standalone debugger? Something to think about.
  • Register grouping
    • Review continues and we aim for 8.6
  • Per-element formatting for expressions and variables
    • Aiming for 8.6 and working out the last one or two remaining issues
  • Example plugin showing how to extend DSF-GDB http://eclip.se/441277
  • New UI
    • Vladimir was going to post to Github and willing to post elsewhere if we wanted.
    • Marc will ping him
  • Stand-alone debugger SWTBot tests
    • Jeff wants to have to SWTBot tests for the Stand-alone debugger
    • We are interested in getting those into CDT
    • Marc-Andre will help configure our HIPP to get it running
    • Jeff will post patch to re-enable autotools SWTBot tests as a first attempt
  • What is the state of lldb MI and working with CDT?
    • Recommendation is to post questions to the list and see
    • Could the stand-alone debugger also work for lldb? It should be easy once CDT support lldb.
  • Should we put effort in supporting Multiple versions of stand-alone debugger for a user?
    • The idea is that if a user has more than one version of CDT installed, only one stand-alone debugger will be setup and it will be the last one the user ran the install script for.
    • The user could copy the stand-alone debugger directory to allow to run more than one version
    • the user could also run the install script for the version she wants as a way to choose the version
    • We probably don't need to address this until there is an explicit request for such support

Attendees

  1. Alvaro Sanchez-Leon (Ericsson)
  2. Marc Dumais (Ericsson)
  3. Xavier Raynaud (Kalray)
  4. Mikhail Khodjaiants (Mentor)
  5. Marc Khouzam (Ericsson)

Minutes

  • CDT 8.5 (Luna SR1)
RC1+1 Aug 18th 2014 Proposed feature freeze and branch point
RC2+1 Sept 1st 2014 Proposed joint test effort
RC3+1 Sept 8th 2014
RC4+1 Sept 15th 2014
Release Sept 26th 2014
  • Content will be small but that is expected as SR1 has barely 2 months of development time.
  • Marc K will email the list to propose the above release process: see email here
  • CDT 8.6 (Luna SR2)
RC1+1 Jan 19th 2015
RC2+1 Feb 2nd 2015
RC3+1 Feb 9th 2105
RC4+1 Feb 16th 2015
Release Feb 27th 2015
  • CDT Logo: Plan is to use http://99designs.ca/ or https://www.designonclick.com/. Doug will take care of it and the Eclipse Foundation will finance it.
  • Using target definitions does not always refresh.
    • Target definitions were updated recently to include mockito but it does not seem to work.
    • There is a bug in PDE that does not refresh the target def properly.
    • Workaround is to open the target def file in an editor and change its version at the top then save. Once refreshed, the version can be reverted.
  • How should target defs be updated?
    • How to use the 'staging' target def vs the others?
  • New UI
    • Progress seems to have stopped. Priorities might have shifted at Mentor.
    • Why not post the existing code in the hopes it could progress through other community members?
  • Register grouping
    • Next round of review completed
    • Targetted for CDT 8.6
  • Per-element formatting for expressions and variables
    • Feature is ready to be committed except for the refreshing issue when dealing with multiple sessions
    • Improvements mentioned by Mikhail (Marc K will open a bug: Bug 441276):
      • Setting format should affect all children, probably not for complex structs but would be great for arrays
      • Should persistence be per-launch?
      • As was first experienced with CDI, some case for this feature are quite complicated. We propose to implement feature in a reasonable way so as to add value, but not to necessarily address each corner case; as long as it does not break normal behavior.
  • Example plugin showing how to extend DSF-GDB
    • DSF-GDB was originally meant to be and example of how to use DSF. It has grown to be extended itself but does not provide an example of how to extend it.
    • Marc K will open a bug to track progress, suggestions and discussions: Bug 441277
    • How to extend the view model elegantly? Does not seem to be a good way. Currently requires a lot of code duplication. We would like to improve that.
  • Suggestion to support a Snapshot feature a la EDC.
    • Idea would be to be able to save a snapshot during a debug session and send it to someone else to examine.
    • Could be implemented relatively easily using core files as snapshots

  6. Marc Khouzam (Ericsson)

Minutes

  • Luna release
    • Coordinated testing was valuable and helped find bugs that would have gone unnoticed
    • Coordinated testing only required 1 to 2 hours of the involved people. Good return on investment
  • Launch bar
    • No update
  • Debug tests on Hudson
    • Debug tests with latest GDB run as part of CDT's master nightly build and part of every Gerrit review build
    • Nighlty jobs added to run tests with GDB version 6.6 to latest. Not all tests pass yet and should be eventually cleaned up or some disabled to get a green light
    • Nightly job to run tests using GDB built from its own master branch and another for GDB's maintenance branch. This allows us to notify the GDB community of regressions that affect CDT before the GDB is released.
  • New UI
    • No update
  • Multi-terminate/disconnect
    • Elegant solution posted and reviewed
    • JUnit tests are harder to write because we have to somehow check that we disconnected or terminated processes
    • Manual tests could be added instead in the test document
  • Pin & Clone for Visualizer
    • Patch available to add a clone button to visualizer. Waiting for review.
    • Will allow to have multiple visualizer views which work with different filters
    • Pin will be worked on to provide even better value for multiple visualizer views
  • Stand-alone
    • -help now supported
    • params after executable are no longer swallowed by eclipse
    • vmargs now supported
    • better path support for binary including support for PATH variable
    • man page to be available
    • handling installations that use dropins, don't mix RPM install with p2 install
