> http://www.roaringpenguin.com/mimedefang/mimedefang-2.20-BETA-1.tar.gz
>
> This is a performance-improving release.  Previously, mimedefang.c
> forked and exec'd "/bin/rm" to clean up the work directory.  I have
> re-implemented this in C so that no forking/execing is required.  This
> can improve performance on systems where it's expensive to fork a
> multithreaded process.  With this implementation, and the right filter
> rules, MIMEDefang can operate without forking and execing at all
(except
> when starting new slaves.)
>
> It should help a lot on busy servers.  I'm looking for people with
> busy servers to test this.  Also, if you read C code, please
> take a look at "rm_r.c" which implements the recursive deletion and
check
> it for sanity.  It looks good to me, but it's easy to make subtle
mistakes...

> Complete changelog since 2.19 follows.

> * mimedefang.c (cleanup): Use an internal C implementation of
> "rm -r" rather than forking and execing /bin/rm.  This should
> improve performance on heavily-loaded systems.

> * configure.in: Added --with-user=LOGIN configure-time option.
> We do not check for existence of this user at configure-time,
> because it would complicate building of RPM.
>
> * RPM creates "defang" user when installed.
>
> * Cleaned up configure script to use AC_MSG_xxx instead of echo
> in a lot of places.
