Thorsten Schöning resolved LOGCXX-306.
--------------------------------------
Resolution: Won't Fix
This seems to be a problem of APR, I don't see how one get provide a share mode
like that for CreateFile under Win32 to apr_file_open. But looking at the
source of the function the following share mode is already applied and should
be good enough for practical use:
DWORD sharemode = FILE_SHARE_READ | FILE_SHARE_WRITE;

> FileAppender --- very aggressive default file locking on Windows since moving
> to APR

> Key: LOGCXX-306
> URL: https://issues.apache.org/jira/browse/LOGCXX-306
> Project: Log4cxx
> Issue Type: Improvement
> Components: Appender
> Affects Versions: 0.10.0
> Environment: Windows XP SP2 on Intel Xeon
> Reporter: Allan Erskine
> Assignee: Curt Arnold
> Priority: Minor
>
> Since moving to APR, the file locking (or sharing attributes perhaps?) of
> FileAppender have become very aggressive.
> The end result is that when my application is logging intensively, I am
> unable to tail, copy, or grep the log file (it generates a permissions
> error!).
> In production environments, this can be a clear no-no --- perhaps this could
> be made configurable (eg if there were performance reasons behind the current
> way of doing things)
