There is a multicoring host declared in platform.xml
<host id="Host" speed="1Gf" core="280" state_file="Failures/Failure/h_0" >
When I rum simulation SimGrid gives me:
[0.000000] /simgrid-master/src/simix/smx_environment.cpp:43: [xbt/CRITICAL] Error while loading /home/Platform/platform.xml: FIXME: add state change code also for constraint_core[i]
How to set state failures properly?
The feature you ask for (applying trace to a multicore host) is not implemented yet, hence the "FIXME" is the error message, which should be a "TODO" or more explicit about the "UNIMPLEMENTED" character of this feature.

I wanted to try out the new address sanitizer for MSVC, and after enabling it in my project I'm getting an access violation exception which the call stack says originates in __acrt_initialize() Line 291. Some research show that this happens before calling the main function, and indeed, a breakpoint on the first line of WinMain is not reached before this happens. With the sanitizer disabled, I am not getting any exceptions.
I have an application where I use TraceListener to collect data/debugging information while application executes. There are more than one listeners at the same time, one of them will write trace information to disk file, other may collect in string (for a short period of execution) and then it will be displayed to user or might saved to another file as per needs.
All went well, unless we decided something else.
We had lot of plugins which were loaded at runtime and executed. However, the issue with that was it was hard to replace the plugin DLL since it was used by application, so we had to stop and replace DLL and then start it again. We decided to use appDomain to load plugin into so that we can easily replace DLL without restarting the application(s).
That was also went well, but one major issue came in. the trace listerns were blind. Since the plugins are loaded into different app domain, so the traces never reached to the parent app domain which was listening to it (the traces made by plugin, which is loaded into new appdomain).
Our trace listener looks like this.
Public Class StringTraceListener
Inherits TextWriterTraceListener
Dim sw As System.Text.StringBuilder = Nothing
Public Overrides Sub WriteLine(ByVal message As String)
Try
MyBase.WriteLine(message)
sw.AppendLine(Now.ToString & " : " & message)
Catch ex As Exception
'Do not write anything here... or it might go into recursive loop
End Try
End Sub
I wonder, if there is a way that we don’t have to make much changes and the trace listener might receive traces from plugins (child appDomain) as well?
Any idea will be appreciated
Thanks
The config is read in when the application is loaded. So for a plug in where the assembly isn't loaded in the usual way, it is plausible that the config isn't being read. You can configure the trace listeners in code, although it is obviously less flexible.
To configure a trace listener in source code, add a listener to the TraceSource's Listener collection. Make sure this happens once for the life of that trace listener, else you will get duplicate Listeners.
I am running my application in VS2012 and I am getting a runtime error;
When I look in the "Original Location" I see mscorlib.dll, but not mscorlib.pdb.
Why is this happening and how do I fix it?
Goto Tools, Options, Debugging, General, Enable Just My Code
This will prevent the debugger from trying to launch on a Internal .NET Framework Assembly.
Goto Tools, Options, Debugging, Symbols and set a cache location. Then hit load in the above and it will fetch the necesary symbols for you and store them in the cache location you provide.
Microsoft's compiler tools create symbols in separate files with a .pdb extension (program database). This allows them to create detached symbols for release binaries. With a symbol server, your IDE can fetch the symbol file matching the specific version of the DLL during debugging. You can configure this system for your own product binaries as well which can be very useful for post-mortem debugging any crashes on end-user machines.
See Microsoft's documentation for more details about using their public symbols.
I had this issue when I was using a static variable, whose value is assigned off a static method.
So, whenever I ran the application, this line of code threw exception. If you place a debug point on this (like I did), you will notice the exception being thrown.
The best Solution to solve this error is:
1: Open App.config file.
2: Paste this useLegacyV2RuntimeActivationPolicy="true" code in the startup tag.
3: Save it.
Now the error would disappear.
Moreover see Image. I have done this for you.
This happened to me for a different reason: I had referenced an old version of NLog (2.0) and needed to reference version 4.0, instead.
In a VB console app, in my case it was none of the above.
Just doing a string calculation in the Dim declarations before my subs.
The offending code:
Dim FylPrefix$ = Fyl.Substring(0, Fyl.LastIndexOf("."))
Moving this calculation into the sub it was needed in fixed it! GERONIMO!!
This can happen when you initialize a variable in your class declarations and that initialization throws an exception:
class Program
{
static OracleConnection ora = getOracleConnection();
}
static void main(string[] args)
{
ora.Open();
}
static OracleConnection getOracleConnection()
{
OracleConnection orax = new OracleConnection(description=(host=myHost)
(port=1521)(protocol=tcp))(connect_data=(sid=mySid)));user id=user;password=pw;
}
If an exception is thrown by getOracleConnection() you can get this error. Move your assignment (but not necessarily your declaration) inside of main (where it belongs anyway), and you will get the actual exception that is causing the error instead of the mscorlib error.
In my case the exception began to appear after I changed the "Assembly name" in the "Application" tab of the properties window. If that's the case with you try reverting to the original name and see if the exception disappears.
Perhaps the reason for this was that the new name did not match the AssemblyTitle in AssemblyInfo.cs.

Occasionally the UnhandledException handler in my app is raised due to an unhandled XAML exception.
The UnhandledExceptionEventArgs contains the message
E_RUNTIME_SETVALUE
and an inner-exception of type ArgumentException
Value does not fall within the expected range.
There is nothing in the call stack other than InitialiseComponent() which I can step into/ over without any exception being thrown.
Any ideas on how to debug further or any experience with E_RUNTIME_SETVALUE issues?
I do remember I had to once add basically no-op value converters to some XAML so I could see what was going on and trace the error. That might help in this case as well.
Also try to turn on mixed-mode debugging to see if more data comes from the native stack.
I had this in UWP and it was because I was using OnIdiom
<OnIdiom x:Key="MyFontSize" x:TypeArguments="x:Double" Tablet="28" Phone="16">
</OnIdiom>
I didn't have desktop included in one of the values and I was running my app on my desktop.
WHen I start VS2012 I always get an exception tellng me to look at ActivityLog.xml. Here is what I see- useless to me. Hoping someone else has seen this before.
Also - VS2012 eats 100% of the CPU on the machine at time. Hoping the two are related and fixable.

Is your VSCommands extension up to date?
There was a compatibility issue which could produce similar stack trace, and it was fixed in latest release.
