SEA Technical Memorandum #0204, SEAdog 4.50; External Event Triggers
Last updated: December 8, 1988

SEAdog 4.50
External Event Triggers
Earlier versions of SEAdog introduced the concept of the "external event
trigger" by allowing the CRASH modifier on an external event and using it
in that fashion. In version 4.50 we have expanded the concept to include
several sorts of triggers, and have added "trigger thresholds".
The complete list of possible event triggers is as follows:
Modifier Triggered by
======== ============
CRASH Receipt of crash priority mail
MAIL Receipt of normal priority mail
FILES Receipt of attached file
REQS Receipt of file request or update request
For example, an external event triggered by receipt of one or more attached
files would be defined thus:
Event X5 all 03:00 09:00 files
Any of these modifiers can be specified at a given threshold by appending a
dash and the threshold value. For example, an external event triggered by
the receipt of five or more files would be defined thus:
Event X5 all 03:00 09:00 files-5
Multiple triggers may be placed on a given event, in which case they
operate in parallel. In other words, consider the following event:
Event X5 all 03:00 09:00 files-5 mail-3 crash
This event would be triggered by the receipt of five or more files, or
three or more normal priority messages, or one or more crash priority
messages.
External event triggers, in conjunction with interruptable mail events,
allow a SEAdog system to perform "instant processing" of received mail.
For example, consider the following:
Event X all 06:00 18:00 mail do group in
Event D all 06:00 18:00
This causes the SEAdog mailer to execute an event D from 06:00 to 18:00,
interrupting it to execute a "group in" command any time mail is received.
