Hi, I have a core dump of mono that I generated with gcore. I want to be able to see the managed call stack of the diffrent threads. With the information I got from here : http://www.mono-project.com/Debugging I thought I'd be able to see it with the mono_stack macro. Unfortunately, it requires a running application and it doesn't work with a core dump (I get the error message "You can't do that without a process to debug." from gdb). I then tried the mono debugger. According to the features list found here (http://www.mono-project.com/Debugger), it is supposed to be able to examine core dumps. Unfortunately, I can't find the documentation on how to do it anywhere. The only thing I found out is that I can use the command "core coreFileName" to load the core dump, but I get an exception when I do this. Here is the exception I get : (mdb) core ./core.27349 Loading core file ./core.27349 ERROR: Caught exception while executing command Mono.Debugger.Frontend.DebuggerEngine: System.EntryPointNotFoundException: mono_debugger_server_get_registers_from_core_file at (wrapper managed-to-native) CoreFileThread:mono_debugger_server_get_registers_from_core_file (intptr,intptr) at Mono.Debugger.Backend.CoreFile+CoreFileThread.read_registers () [0x00079] in /home/jonathang/trunk/debugger/backend/arch/CoreFile.cs:238 at Mono.Debugger.Backend.CoreFile+CoreFileThread..ctor (Mono.Debugger.Backend.CoreFile core, Int32 pid) [0x00038] in /home/jonathang/trunk/debugger/backend/arch/CoreFile.cs:217 at (wrapper remoting-invoke-with-check) CoreFileThread:.ctor (Mono.Debugger.Backend.CoreFile,int) at Mono.Debugger.Backend.CoreFile.read_note_section () [0x00053] in /home/jonathang/trunk/debugger/backend/arch/CoreFile.cs:146 at Mono.Debugger.Backend.CoreFile..ctor (Mono.Debugger.Backend.ThreadManager manager, Mono.Debugger.Backend.ProcessStart start) [0x00077] in /home/jonathang/trunk/debugger/backend/arch/CoreFile.cs:66 at (wrapper remoting-invoke-with-check) Mono.Debugger.Backend.CoreFile:.ctor (Mono.Debugger.Backend.ThreadManager,Mono.Debugger.Backend.ProcessStart) at Mono.Debugger.Backend.CoreFile.OpenCoreFile (Mono.Debugger.Backend.ThreadManager manager, Mono.Debugger.Backend.ProcessStart start) [0x00000] in /home/jonathang/trunk/debugger/backend/arch/CoreFile.cs:21 at Mono.Debugger.Backend.ThreadManager.OpenCoreFile (Mono.Debugger.Backend.ProcessStart start, Mono.Debugger.Thread[]& threads) [0x00000] in /home/jonathang/trunk/debugger/backend/ThreadManager.cs:111 at (wrapper remoting-invoke-with-check) Mono.Debugger.Backend.ThreadManager:OpenCoreFile (Mono.Debugger.Backend.ProcessStart,Mono.Debugger.Thread[]&) at Mono.Debugger.Backend.DebuggerServant.OpenCoreFile (Mono.Debugger.DebuggerSession session, System.String core_file, Mono.Debugger.Thread[]& threads) [0x00020] in /home/jonathang/trunk/debugger/backend/DebuggerServant.cs:169 at (wrapper remoting-invoke-with-check) Mono.Debugger.Backend.DebuggerServant:OpenCoreFile (Mono.Debugger.DebuggerSession,string,Mono.Debugger.Thread[]&) at Mono.Debugger.Debugger.OpenCoreFile (Mono.Debugger.DebuggerSession session, System.String core_file, Mono.Debugger.Thread[]& threads) [0x00006] in /home/jonathang/trunk/debugger/classes/Debugger.cs:153 at (wrapper remoting-invoke-with-check) Mono.Debugger.Debugger:OpenCoreFile (Mono.Debugger.DebuggerSession,string,Mono.Debugger.Thread[]&) at Mono.Debugger.Frontend.Interpreter.OpenCoreFile (System.String core_file) [0x00000] at (wrapper remoting-invoke-with-check) Mono.Debugger.Frontend.Interpreter:OpenCoreFile (string) at Mono.Debugger.Frontend.OpenCoreFileCommand.DoExecute (Mono.Debugger.Frontend.ScriptingContext context) [0x00000] at Mono.Debugger.Frontend.DebuggerCommand.Execute (Mono.Debugger.Frontend.ScriptingContext context) [0x00000] at Mono.Debugger.Frontend.DebuggerCommand.Execute (Mono.Debugger.Frontend.Engine e) [0x00000] at Mono.Debugger.Frontend.Engine.Run (System.String s, System.Collections.ArrayList args) [0x00000]
Is this supposed to work and if it is, how can I get it to work? Otherwise, is there any other way that I could get the managed call stack of the threads from a core dump? Thanks, Jonathan
