WorldRobertProject opened a new issue, #163:
URL: https://github.com/apache/logging-log4net/issues/163
When RollingStyle is Composite, it seems RollingFileAppender ignores
AppendToFile flag except for the first log on that day.
The following code makes log files as 2024-08-02.0.log, 2024-08-02.1.log, ...
### log4net.config.xml
```xml
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<log4net>
<appender name="LogFileAppender"
type="log4net.Appender.RollingFileAppender">
<param name="File" value=".\Log\" />
<param name="AppendToFile" value="true" />
<param name="RollingStyle" value="Composite" />
<param name="DatePattern" value='yyyy-MM-dd".log"' />
<param name="MaximumFileSize" value="5MB" />
<param name="MaxSizeRollBackups" value="10" />
<param name="StaticLogFileName" value="false" />
<param name="CountDirection" value="1" />
<param name="PreserveLogFileNameExtension" value="true"/>
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy/MM/dd HH:mm:ss.fff}
[%-5p] %m (%M)%n"/>
</layout>
</appender>
<logger name="log">
<level value="debug" />
<appender-ref ref="LogFileAppender" />
</logger>
</log4net>
</configuration>
```
### Program.cs
```c#
using log4net;
using log4net.Config;
using System.Reflection;
var pathConfig = Path.Combine(AppDomain.CurrentDomain.BaseDirectory,
"log4net.config.xml");
XmlConfigurator.Configure(new FileInfo(pathConfig));
var assembly = Assembly.GetEntryAssembly();
var logger = LogManager.GetLogger(assembly, "log");
logger.Info("Hello, log4net!");
```
When only 2024-08-02.0.log exists, it appends a new log to 2024-08-02.0.log
as expected.
When both 2024-08-02.0.log and 2024-08-02.1.log exist and 2024-08-02.0.log
is greater than 5MB, this code overwrites 2024-08-02.1.log and outputs the
following error message:
> log4net:ERROR RollingFileAppender: INTERNAL ERROR. Append is False but
OutputFile [...\Log\2024-08-02.1.log] already exists.
It seems AppendToFile flag is ignored.
All log4net versions from 2.0.10 to 2.0.17 reproduce this issue.
