Title: Re: [Firebird-devel] Proposal of new feature: Event triggers
Jim, as I said before, I'm not proposing a substitute for the currently Firebird events. It is a new feature. Of course, if current events implementation is weak and/or bugged, it would be nice to have it improved or fixed, but this is independent of what I'm proposing.

Firebird events needs a listening client. The new feature would not need a client at all.

Carlos, again, why not figure out why events aren't working at your site.  It is a mechanism designed from the beginning to do what you want, e.g. notify other connections of a database state change.

What you are suggesting will introduce far more problems than it purports to solve.

If there is is a Firebird bug, isolate it so somebody can fix it.  If it is your bug, fix it yourself.

If it's a firewall problem (the original code was written long before firewalls were invented), change re secondary connection mechanism to use the primary port.

Exactly. I have no idea about how context variables was implemented
internally, but do you think there is a chance to make them respect
the isolation of its transaction when retrieving the values?
