[Mono-dev] Profiler and coverage problem?

[Csaba Balazs]

Hi,

I try to check the monocov (0.2) tool for testing the code coverage.

I have found something unclear.

A small sample:

using System;
using System.Xml;

public class MinProba {
	public static void Main(String[] args) {
		XmlTextReader reader = new XmlTextReader("test.xml");
		reader.Read();
		reader.Close();
	}
}

The test.xml is just a sample.

Compiling:
gmcs -debug MinProba.cs    or    mcs -debug MinProba.cs

Running with monocov:
mono --debug --profile=monocov MinProba.exe

Result:
Dumping coverage data to MinProba.exe.cov ...
Done.


At the point of "reader.Read()" we call the System.Xml.XmlTextReader Read
method.

Its source (from XmlTextReader.cs):

public override bool Read ()
{
    ...
    if (Binary != null)
       Binary.Reset ();
    ...
}

This Binary property is from the parent class (XmlReader).
There is no "XmlReader.get_Binary" method tag in the generated COV file, but it
obviously called. Only the XmlReader .ctor call tag is there.

If I use the "mono --debug --trace MinProba.exe", the problem is the same.

I have disassembled the System.Xml.dll, and this function call is there!

What is wrong? Is it a monocov or mono profiler interface problem?

Thank you in advance,

Csaba
