Installed mono 1.9.1 package on MacOSX 10.4.11 (macbook pro).
Code :
using System;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
FileSystemWatcher f = new FileSystemWatcher(args[0]);
f.IncludeSubdirectories = true;
f.InternalBufferSize = 5000000;
f.EnableRaisingEvents = true;
f.Created += new FileSystemEventHandler(f_Created);
f.Changed += new FileSystemEventHandler(f_Created);
f.Deleted += new FileSystemEventHandler(f_Created);
while (true)
{
f.WaitForChanged(WatcherChangeTypes.All);
}
}
static void f_Created(object sender, FileSystemEventArgs e)
{
Console.WriteLine(e.ChangeType + &quot; : &quot; + e.FullPath);
}
}
}
Test script :
#!/bin/bash
TESTDIR=/tmp/fswatcher.dir
function watch() {
install -d $1
(
mono fswatcher.exe $1 | while read LINE
do
echo &quot;[`date`] $LINE&quot;
done
) &amp;
}
function at() {
sleep $1
echo &quot;[`date`] $2&quot;
eval $2
}
watch $TESTDIR
at 1 &quot;touch $TESTDIR/bla.txt&quot;
at 1 &quot;echo a &gt;&gt; $TESTDIR/bla.txt&quot;
at 5 &quot;touch $TESTDIR/bla2.txt&quot;
sleep 1
killall mono
rm -rf $TESTDIR
Output :

[Mon Sep 22 09:48:46 CEST 2008] Changed : /tmp/fswatcher.dir/bla.txt

Expected result : the changed() event for 'echo a &gt;&gt; ...' should have fired
after the call, not after the creation of a second file. In other words, the
output should look like :

[Mon Sep 22 09:48:41 CEST 2008] Changed : /tmp/fswatcher.dir/bla.txt
