Feature Idea: MailScanner process name

[Steve Freegard]

Hi Julian,

I was looking at a live system recently when I came up with the idea of
changing the MailScanner process name according to what it is doing
(similar to sendmail - where you can see exactly what it is doing by
running 'ps').

For example - in the current version a 'ps -o pid,state,command -xf' on
a Linux-based MailScanner system will give you something like:

 6089 S sendmail: accepting connections
 6098 S sendmail: Queue runner at 00:15:00 for /var/spool/mqueue
 6116 S /usr/bin/perl -I/usr/lib/MailScanner /usr/sbin/MailScanner /etc
 4402 S \_ /usr/bin/perl -I/usr/lib/MailScanner /usr/sbin/MailScanner
10084 S \_ /usr/bin/perl -I/usr/lib/MailScanner /usr/sbin/MailScanner
14729 S \_ /usr/bin/perl -I/usr/lib/MailScanner /usr/sbin/MailScanner
21996 S \_ /usr/bin/perl -I/usr/lib/MailScanner /usr/sbin/MailScanner
28135 S \_ /usr/bin/perl -I/usr/lib/MailScanner /usr/sbin/MailScanner

So I modified several files to set the process name according to the
action being taken - which then gives:

 3353 S sendmail: accepting connections
 3362 S sendmail: Queue runner at 00:15:00 for /var/spool/mqueue
 3413 S MailScanner
 3486 S  \_ MailScanner: Waiting for messages
 3497 S  \_ MailScanner: Waiting for messages
 3509 S  \_ MailScanner: Waiting for messages
 3518 S  \_ MailScanner: Waiting for messages
 3528 S  \_ MailScanner: Waiting for messages

and when a batch is being processed:

 3413 S MailScanner
 3486 S  \_ MailScanner: Waiting for messages
 3497 S  \_ MailScanner: Waiting for messages
 3509 S  \_ MailScanner: Waiting for messages
 3518 S  \_ MailScanner: Virus Scanning
 3547 Ss |   \_ /bin/sh /usr/lib/MailScanner/clamav-wrapper / 
 3552 R  |     \_ /usr/bin/clamscan --unzip --jar --tar --t
 3528 S  \_ MailScanner: Waiting for messages

I'm not sure how portable this is across systems or if anyone other than
me might find this useful (plus a lot of testing would be needed as
check_MailScanner needed modification), but I've attached the diffs each
of the modified files again the current stable release.

What do you think??

Cheers,
Steve.
