Michel Emond updated LOG4NET-465:
---------------------------------
Attachment: config.xml
RollingFileAppender.diff
> Rolling log files get overwritten when IIS is restarted
> -------------------------------------------------------
>
> Key: LOG4NET-465
> URL: https://issues.apache.org/jira/browse/LOG4NET-465
> Project: Log4net
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 1.2.13
> Environment: asp.net 4.0
> Reporter: Michel Emond
> Attachments: RollingFileAppender.diff, config.xml
>
>
> Reproduction steps
> - Setup a web application using the settings from the attached config.xml file
> - Notice the rolling style set to Composite
> - Start and use the application
> - The log files pile up in the folder
> - Restart IIS
> - Keep using the application
> Expected result
> - The rolling continues on or after the last file
> Actual result
> - The rolling restarts at index 1 and overwrites the existing files
> Solution
> See the attached files:
> - config.xml
> - patch with a fix proposal
> The original bug fix addresses the issue in the InitializeFromOneFile()
> method.
> However, the GetWildcardPatternForFile() method also needs the baseFileName
> to be adjusted with the datePattern so the proper files are searched.
> I placed a file path fix in the DetermineCurSizeRollBackups() method, so it's
> then passed down to the two other methods and everyone gets happy.
> Here's a calling stack sample:
> DetermineCurSizeRollBackups()
> |
> +--GetExistingFiles()
> | +--GetWildcardPatternForFile()
> |
> +--InitializeRollBackups()
> +--InitializeFromOneFile()
