WinDbg Preview 220.127.116.11 Release Notes
We’re back and rolling out our first major update since TTD was announced! We’ve loved reading through your tweets, feedback, and blog posts about it. Don’t forget to read through the feedback hub and upvote the requests that you like! If you hit any issues with this build, don’t hesitate to leave a comment or submit it in the Feedback Hub.
Better process server experience
WinDbg’s handling of process server (DbgSrv) remotes tends to be confusing around what is actually being debugged, and WinDbg Preview would disconnect from remotes a bit more often than is convenient. We’ve added a notification in the File menu to show what process server you’re connected to and interacting with.
As part of this, when ending a debugging session, the process server connection will persist and can be disconnected in the File menu.
New default layout options
We’ve added a “Layouts” option in the “View” ribbon. There are currently three layouts: the default, one focused on disassembly, and one minimal. We’re looking for feedback on if these layouts are useful or if they could be changed to be more valuable.
Minor changes and bug fixes
- Fixed formatting of conditional ribbon tabs to be less confusing.
- Re-worked DML to be stricter in parsing to improve performance.
- Various fixes with the performance and behavior of ctrl+F.
- Added a warning when running un-elevated prior to trying to use TTD.
- Added the option to override automatic target bitness detection.
- Disabled various file menu and ribbon options when they can’t be used (like “Go” when in a dump file).
Time Travel Debugging
We’ve been hard at working fixing some bugs and prioritizing your feedback, so we only have a few time travel debugging updates for this release.
One key piece of feedback we need more data on is this one. We are looking at many ways for recording TTD traces without installing WinDbg, but we want to learn more about how you want to record before deciding on a solution. Anyone interested in that can comment on that feedback (or this post) to let us know why you want a standalone TTD recorder, why WinDbg doesn’t work for you or how you would use a TTD recorder differently than WinDbg.
Time Travel Debugging ribbon
We’ve added a slightly more advanced Time Travel ribbon that will show up when debugging a time travel debugging trace. We’ll be growing this ribbon over time, so send us feedback if you have something you think should be added to this ribbon.
- SOS will not work on x86 traces.
Changes in API version 1.1 include:
- host.getModuleSymbol and host.getModuleType return null if they cannot find the symbol instead of throwing an exception.
- All native objects have the address property on them in addition to .targetLocation. If the object does not have an address, an exception will be thrown when accessing the property.
There’s many other bug fixes and improvements, here are the notable ones:
- The breakpoint command in the script debugger can now break on function names in addition to line/column positions.
