WinDbg Preview 1.1712.15003 Release Notes
TTD memory queries
You can now query TTD for memory accesses similar to how you query for calls today. This allows you to find all of the reads, writes and execution which access a specific range of memory.
- Read and write example: dx @$cursession.TTD.Memory(startAddress, endAddress, "rw")
- Unique execution example: dx @$cursession.TTD.Memory(startAddress, endAddress, "ec")
One of the top requests and complaints right now is the loading and saving of settings, specifically around workspaces. Our initial approach to preserving settings in WinDbg Preview has been very conservative, and we rarely preserves settings from one session to another, and it always requires explicitly loading the workspace.
The first piece of this is in this release. WinDbg Preview will now automatically save settings between sessions, including your symbol path and source path. More will be coming soon like breakpoints and other session specific settings! Keep an eye out for the announcement of the new functionality, and don’t hesitate to send any feedback on the changes you do notice.
We’re starting to look at the start-up performance, this update has ~20-30% improvement in launch time after the first launch.
- If the method implements .compareTo(other), it is comparable (comparison operators work in dx and LINQ). If the method returns a negative value, such as “this < other”. If the method returns zero, “this == other”. If the method returns a positive value “this > other”.
- If the method implements .equals(other), it is equatable (== works in dx and LINQ). The method must return either true or false.
