-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
MIMEDefang 2.57-BETA-1 is available from the download page: http://www.mimedefang.org/node.php?id=1 This release contains a few bug fixes plus two new features. The new features are: 1) A new "md-mx-ctrl hload" command that is analogous to md-mx-ctrl load, but shows load averaged over the last 1, 4, 12 and 24 hours. 2) And controversially: A change to the slave-scheduling algorithm. In previous versions, when the multiplexor went to pick a slave to do work, it picked the oldest available slave, where "age" is measured by how long ago the slave process was started. The new algorithm works as follows: For a given command (relayok, senderok, recipok and scan), pick the oldest slave that previously ran that same command. If there is no such slave, pick the oldest slave. What this means is that all your "filter_recipient" functions will tend to run on one slave (or one group of slaves), and the content-filtering functions (filter_begin, etc.) will tend to run on another slave or group of slaves. This change is experimental; the theory is that if we can lazily load modules, then slaves that spend their entire lifetime doing "filter_recipient" calls won't need to load big Perl modules like SpamAssassin at all. (Currently, the sample filter does NOT do lazy module loading, so the scheduling change makes no difference yet, but we may rework the filter to take advantage of it.) The reason I said the change is controversial is this: If you have a working filter that "accidentally" relies on state being preserved across filter_relay/filter_sender/filter_recipient/filter_begin, that filter will almost certainly STOP WORKING. Whereas with older versions of MIMEDefang, such filters would fail only occasionally, with the new version, they will fail almost all the time. In my opinion, this is a Good Thing, because it exposes buggy filters quickly. Nevertheless, do not upgrade to 2.57 unless you're quite sure your filter is correct. Full changelog follows. Regards, David. 2006-05-04 David F. Skoll <[EMAIL PROTECTED]> * VERSION 2.57-BETA-1 RELEASED * Minor fixes to man pages. Some cleanups courtesy of Brandon Hutchinson * mimedefang-multiplexor.c: New "md-mx-ctrl hload" command keeps track of load for past 1, 4, 12 and 24 hours. Gives long-term data to complement the short-term "md-mx-ctrl load" data. * mimedefang-multiplexor: New scheduling algorithm tries to keep commands "sticky". For example, when looking for a slave to run "recipok", we prefer to use a slave that recently ran "recipok". NOTE!!! If your filter incorrectly retains state from earlier callbacks into filter_begin, this scheduling change WILL expose the bugs in your filter. * mimedefang.c: Bug fix for NULL pointer dereference when running "sendmail -bs". Problem noted by Leena Heino. * mimedefang.pl.in: Fix for FPROTD integration courtesy of Jonathan Hankins. * mimedefang.pl.in: Fix for H+BEDV integration courtesy of Thorsten Schlichting. * mimedefang.pl.in: Pass LOCAL_STATE_DIR => '/var/lib' to Mail::SpamAssassin constructor. If your LOCAL_STATE_DIR is elsewhere, you'll have to hack the Perl code, I'm afraid. 2006-02-13 David F.
