NetAddr::IP's use of $& and $`

Post #1 of 5 (4061 views)

Hi Luis and Michael,

Would you be able to consider reworking NetAddr::IP to avoid the use of,
or loading of anything that uses, $& or $` so that the huge speed
penalty imposed by Perl when doing so can be avoided?

NetAddr::IP is used by Mail::SPF which is used by Mail::SpamAssassin.
Apache SpamAssassin needs to avoid the speed penalty imposed by $& and
$` at all costs.

Please see SpamAssassin bug 5312 for some background on this:
http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5312

Thanks!

Regards,

I will install it and run a make test for both Mail::SPF and
Mail::SpamAssassin (it does some more SPF testing).

I'll also forward a copy to Mark Martinec (amavisd-new maintainer) who
spotted the issue and Julian Mehnle (Mail::SPF maintainer).

No problem. Thank you for the super fast response!

Please let me know too so I can get Ubuntu updated.

NetAddr::IP v4.007 removes everything that would cause PL_sawampersand
to be set to true.

The next Mail::SPF release will explicitly _recommend_ NetAddr::IP v4.007,
but will (obviously) still _strictly_require_ only v4.000.

Present Mail::SPF releases should work fine as-is with NetAddr::IP v4.007.
