There is native C++ application that hosts several .net components. When some error occurs this application creates mini dump using MiniDumpWriteDump function. Question here what is minimum set of
[Flags ]enum MINIDUMP_TYPE {
MiniDumpNormal = 0x00000000,
MiniDumpWithDataSegs = 0x00000001,
MiniDumpWithFullMemory = 0x00000002,
MiniDumpWithHandleData = 0x00000004,
MiniDumpFilterMemory = 0x00000008,
MiniDumpScanMemory = 0x00000010,
MiniDumpWithUnloadedModules = 0x00000020,
MiniDumpWithIndirectlyReferencedMemory = 0x00000040,
MiniDumpFilterModulePaths = 0x00000080,
MiniDumpWithProcessThreadData = 0x00000100,
MiniDumpWithPrivateReadWriteMemory = 0x00000200,
MiniDumpWithoutOptionalData = 0x00000400,
MiniDumpWithFullMemoryInfo = 0x00000800,
MiniDumpWithThreadInfo = 0x00001000,
MiniDumpWithCodeSegs = 0x00002000,
MiniDumpWithoutManagedState = 0x00004000,
};
that should be passed to MiniDumpWriteDump to produce small dump file but with ability to see clr stack)? Sure, full memory dump will work but how to get only bearable minimum?
回答1:
In fact, it is enough to specify these options (to make dump small and be able to extract managed callstacks):
- MiniDumpNormal (default)
- MiniDumpWithProcessThreadData
- MiniDumpWithThreadInfo
- MiniDumpWithUnloadedModules
Thanks a lot to Oleg Starodumov form http://debuginfo.com/

As far as I know, you need a full dump. The reason is that to decode the stack contents you need memory that's privately allocated by the CLR (such as JITted methods).
It is theoretically possible to add these memory regions by hand to a smaller dump, but of the enum values you listed above, I'm afraid only the full dump will contain that information.
