+NAME
+ Mail::SpamAssassin::AsyncLoop - scanner asynchronous event loop
+
+DESCRIPTION
+ An asynchronous event loop used for long-running operations, performed
+ "in the background" during the Mail::SpamAssassin::check() scan
+ operation, such as DNS blocklist lookups.
+
+METHODS
+ $obj = $async->start_lookup($obj)
+ Register the start of a long-running asynchronous lookup operation.
+ $obj is a hash reference containing the following items:
+
+ key (required)
+ A key string, unique to this lookup. This is what is reported in
+ debug messages, used as the key for "get_lookup()", etc.
+
+ id (required)
+ An ID string, also unique to this lookup. Typically, this is the
+ DNS packet ID as returned by DnsResolver's "bgsend" method.
+ Sadly, the Net::DNS architecture forces us to keep a separate ID
+ string for this task instead of reusing "key" -- if you are not
+ using DNS lookups through DnsResolver, it should be OK to just
+ reuse "key".
+
+ type (required)
+ A string, typically one word, used to describe the type of
+ lookup in log messages, such as "DNSBL", "MX", "TXT".
+
+ poll_callback (optional)
+ A code reference, which will be called periodically during the
+ background-processing period. If you will be performing an async
+ lookup on a non-DNS-based service, you will need to implement
+ this so that it checks for new responses and calls
+ "set_response_packet()" or "report_id_complete()" as
+ appropriate. DNS-based lookups can leave it undefined, since
+ DnsResolver::poll_responses() will be called automatically
+ anyway.
+
+ The code reference will be called with one argument, the $ent
+ object.
+
+ completed_callback (optional)
+ A code reference, which will be called when the lookup has been
+ reported as complete via "set_response_packet()" or
+ "report_id_complete()".
+
+ The code reference will be called with one argument, the $ent
+ object.
+
+ $obj is returned by this method.
+
+ $obj = $async->get_lookup($key)
+ Retrieve the pending-lookup object for the given key $key.
+
+ If the lookup is complete, this will return "undef".
+
+ Note that a lookup is still considered "pending" until
+ "complete_lookups()" is called, even if it has been reported as
+ complete via "set_response_packet()" or "report_id_complete()".
+
+ @objs = $async->get_pending_lookups()
+ Retrieve the lookup objects for all pending lookups.
+
+ Note that a lookup is still considered "pending" until
+ "complete_lookups()" is called, even if it has been reported as
+ complete via "set_response_packet()" or "report_id_complete()".
+
+ $alldone = $async->complete_lookups()
+ Perform a poll of the pending lookups, to see if any are completed;
+ if they are, their <completed_callback> is called with the entry
+ object for that lookup.
+
+ If there are no lookups remaining, or if too long has elapsed since
+ any results were returned, 1 is returned, otherwise 0.
+
+ $async->abort_remaining_lookups()
+ Abort any remaining lookups.
+
+ $async->set_response_packet($id, $pkt)
+ Register a "response packet" for a given query. $id is the ID for
+ the query, and must match the "id" supplied in "start_lookup()".
+ $pkt is the packet object for the response.
+
+ If this was called, $pkt will be available in the
+ "completed_callback" function as "$ent-<gt"{response_packet}>.
+
+ One or the other of "set_response_packet()" or
+ "report_id_complete()" should be called, but not both.
+
+ $async->report_id_complete($id)
+ Register that a query has completed, and is no longer "pending". $id
+ is the ID for the query, and must match the "id" supplied in
+ "start_lookup()".
+
+ One or the other of "set_response_packet()" or
+ "report_id_complete()" should be called, but not both.
+
+ $time = $async->get_last_start_lookup_time()
+ Get the time of the last call to "start_lookup()". If
+ "start_lookup()" was never called or "abort_remaining_lookups()" has
+ been called "get_last_start_lookup_time()" will return undef.

+
+SYNOPSIS
+DESCRIPTION
+ This module implementes a PostgresSQL specific bayesian storage module.
+
+ It subclasses Mail::SpamAssassin::BayesStore::SQL and overrides any
+ methods which makes SQL calls involving the token column. Since
+ PostgreSQL uses BYTEA for the token column type you must make sure that
+ the DBD driver does the proper quoting. You can accomplish this by
+ binding the token column to a specific type.
