- Add pointerSize() to Provider base; WoW64/ELF detection in ProcessMemory, WinDbg, and RemoteProcessMemory plugins - Wire pointer size through NodeTree, source/XML imports, C++ generator, controller, compose, address parser, and RPC protocol header - Add is32Bit to PluginProcessInfo and ProcessInfo; show (32-bit) in picker - Scanner rescan now filters results against the current input value - Go-to-address from scanner resets change tracking to prevent false flashing

/**
|
|
* WinDbg memory provider
|
|
*
|
|
* Uses DbgEng to read memory from:
|
|
* - An existing WinDbg debug server via DebugConnect (tcp/npipe)
|
|
* - A live process by PID via DebugCreate (non-invasive attach)
|
|
* - A crash dump (.dmp) file via DebugCreate
|
|
*
|
|
* Target string format:
|
|
* "tcp:Port=5055,Server=localhost" - connect to WinDbg debug server (TCP)
|
|
* "npipe:Pipe=name,Server=localhost" - connect to WinDbg debug server (named pipe)
|
|
* "pid:1234" - attach to process 1234
|
|
* "dump:C:/path/to/file.dmp" - open dump file
|
|
*
|
|
* Threading: All DbgEng COM calls are dispatched to the thread that created
|
|
* the connection (DebugConnect/DebugCreate). This is required because the
|
|
* remote transport (TCP/named-pipe) binds to the creating thread. The
|
|
* controller's background refresh threads call read() which transparently
|
|
* marshals to the owning thread via BlockingQueuedConnection.
