[DOTNET-ROTOR] Method Entry/Return
How do we capture each method invocation and return? Is it possible to capture its information as well? Thank you very much. === This list is hosted by DevelopMentor® http://www.develop.com NEW!

Re: [DOTNET-ROTOR] Method Entry/Return
Take a look at the profiler, in sscli\samples\utilities\dnproprofiler. There is a dnprofiler.html that describes a bit about the profiler interface. You should be able to use the JITCOmpilationStarted() callback to instrument each method's IL as it is jitted.

Re: [DOTNET-ROTOR] Method Entry/Return
The CProfilerCallBack::JITCompilationStarted function only displays the
method name that is being jitted.
if ( GetMethodNameFromFunctionId( functionId, wszClass, wszMethod ) )
{
ProfilerPrintf(JITCompilationStarted: %ls::%ls\n,wszClass,wszMethod);
}
else
{
ProfilerPrintf( JITCompilationStarted\n );
}
I found that the GetMethodNameFromFunctionId function is a helper function
to find the method name only.
How would we use the JITCompilationStarted() callback to instrument each
method's IL as it is jitted?
Moreover, when I set the DN_PROFILER_MASK to, for example, 0x20, the
profiler crashed. It complained: Fatal stack overflow error.
Thank you.

[DOTNET-ROTOR] Embedding rotor w/ Platform COM?
After peering at rotor for a while, it seems that if COM exists on the platform, you could write an alternate PAL that took advantage of the native COM. It seems that you could get interop out of rotor into COM objects that way. However, I'm also interested in hosting the rotor runtime by a native COM client. I didn't see a way to do this offhand. Is this feasible? Is the code in rotor somewhere, or would I have to write my own COM wrapper? Thanks, nh === This list is hosted by DevelopMentor® http://www.develop.com NEW!

Re: [DOTNET-ROTOR] Embedding rotor w/ Platform COM?
You could host Rotor in-process inside a native app using the same mechanism that clix.exe uses: call Win32 LoadLibrary() on mscoree.dll, then GetProcAddress for _CorExeMain2 and call it. You *might* need to first call LoadLibrary() on rotor_pal.dll and call its PAL_Initialize() before loading mscoree.dll, just to be sure that the PAL is ready to go. sscli\docs\techinfo\native_managed_interop.html describes Rotor's Foreign Function Interface (FFI) which can be used to make calls from native C/C++ code into managed code. It would be a logical starting place to build an interop layer that wraps a managed object with a COM object.

Re: [DOTNET-ROTOR] Build rotor with visual studio.net?
The problem you are seeing is caused by optimization settings. The default Rotor build flavor is fastchecked: both optimizations and debugging instrumentation are turned on. Try using the checked build flavor of Rotor. Setup the environment by running env.bat checked and then do buildall as usual. The checked build flavor has optimizations turned off so you should be able to watch all variables, etc. On the other hand, the checked build flavor is significantly slower. -Jan This posting is provided AS IS with no warranties, and confers no rights. -Original Message- From: Discussion of the Rotor Shared Source CLI implementation [mailto:[EMAIL PROTECTED] On Behalf Of Sun, Yulin Sent: Wednesday, November 26, 2003 5:59 PM To: [EMAIL PROTECTED] Subject: [DOTNET-ROTOR] Build rotor with visual studio.net? I found it was diffcult to debug rotor with visual studio.net with devenv \debugexe clix helloworld.exe because some variable can't watch from the watch window. Therefore I want to rebuild the rotor with visual studio.net instead of the buildall of the rotor, but I failed to do so. Has someone been success to do so or have some experience to do so?

Re: [DOTNET-ROTOR] Method's IL Modification
Check Rewrite MSIL Code on the Fly with the .NET Framework Profiling API article on MSDN: http://msdn.microsoft.com/msdnmag/issues/03/09/NETProfilingAPI/default.a spx . It should have answers to all your questions. Note that there is bug in the profiler implementation in the final Rotor v1 release - more details are at http://www.mail-archive.com/[EMAIL PROTECTED]/msg00511.ht ml. You may also want to a look at ICorProfilerInfo::SetEnterLeaveFunctionHooks. It gives you simple Enter/Leave callbacks without rewriting the IL. -Jan This posting is provided AS IS with no warranties, and confers no rights. -Original Message- From: Discussion of the Rotor Shared Source CLI implementation [mailto:[EMAIL PROTECTED] On Behalf Of SUBSCRIBE DOTNET-ROTOR Memomana Sent: Wednesday, November 26, 2003 8:11 PM To: [EMAIL PROTECTED] Subject: [DOTNET-ROTOR] Method's IL Modification I have followed the guide to use Get/SetILFunctionBody posted a while ago by Jan Kotas. The code works fine in my Rotor build. I would like to modify the code so that the Main method displays a Please Help message before returning. i.e. if the original Main method displays Hello World, then the new code will make it display Hello World AND Please Help. In other words, the difference with Jan's code is that instead of replacing the original Main method's IL by a new IL to display Hello World, my intention is to keep the original Main method's IL and add other new ILs (in this case, IL to display Please Help message). I have managed to augment the IL code for displaying Please Help before Main returns. Original IL code: 13 30 01 00 0b 00 00 00 00 00 00 00 72 01 00 00 70 28 02 00 00 0a 2a My modified IL code: 13 30 01 00 0b 00 00 00 00 00 00 00 72 01 00 00 70 28 02 00 00 0a [72 1c 00 00 70 28 02 00 00 0a] 2a The brackets are included only for easy reading. Basically, I copied the original bytecode into a new (BYTE *) variable, say BYTE *X. Then, the last original bytecode (i.e. 2a) is copied to be the last bytecode of X. In between, I inserted the [72 1c 00 00 70 28 02 00 00 0a]. However, the Rotor complained: VALIDATION FAILS: inPtr + sizeof(unsigned int) = inBuffEnd At World.HelloWorld::Main at a Unhandled Exception: System.InvalidProgramException: Common Language Runtime detected an invalid program. at World.HelloWorld.Main() I figured that the new IL is not valid since, obviously, the size of the IL code is larger. #1 How would we determine how much bigger? #2 How would we set the new size back using the SetILFunctionBody function? #3 Any other (better) way to instrument the method's IL code?
