eimhof opened a new issue, #244:
URL: https://github.com/apache/logging-log4net/issues/244
I just updated from v3.0.4 to 3.1.0 and suddenly logging fails with an
ArgumentException ("The path is not of a legal form.")
Stack:
```
at System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32
maxPathLength, Boolean expandShortPaths)
at System.IO.Path.InternalGetDirectoryName(String path)
at log4net.Appender.RollingFileAppender.InitializeFromOneFile(String
baseFile, String curFileName)

baseFile, IList`1 arrayFiles)

```
It turns out that when there's already a file present in the target
directory, above mentioned error is thrown.
Below a repro - first time you run it, it will work because no file is
present. The second time it fails:
```
static void Main(string[] args)
{
PatternLayout patternLayout = new PatternLayout
{
ConversionPattern = @"%date [%thread] %-5level %logger
[%property{NDC}] - %message%newline"
};
patternLayout.ActivateOptions();
RollingFileAppender rollingFileAppender = new RollingFileAppender
{
AppendToFile = true,
File = @"C:\TempLog\",
Layout = patternLayout,
DatePattern = "yyyy-MM-dd'.log'",
MaxSizeRollBackups = 10,
MaximumFileSize = "5MB",
RollingStyle = RollingFileAppender.RollingMode.Composite,
StaticLogFileName = false,
};
rollingFileAppender.ActivateOptions();
}
```
