Add a button to Zone page to force immediate slave notify

We should have a button on the zone records list page that would call PUT /servers/{server_id}/zones/{zone_id}/notify forcing an immediate manual notify to all name servers.

This would be useful in situations where for whatever reason the first notify failed, or if a new slave is brought online. Currently, you would need to make a dummy change to force a renotify.

I’d also like to see a NOTIFY sent whenever a zone is edited, as soon as the changes are saved. Currently there’s a bit of a delay with notifying the secondaries receiving the update as it relies on PowerDNS noticing that the zone has changed, and it only polls for that every slave-cycle-interval interval.

Hello,

While this could be an option, we have to figure out if it does what you would like first. Reading the conversation, none of you does.

@sshipway if you still would like to reduce notification delay, you could start by running a simple test:

• live display detailed logs of PDNS or run a tcpdump on slaves
• Do a simple change directly via PDNS API (like changing a tll or a record content)
• Monitor how long it takes to the master to send notification
• Do multiple iterations to confirm the behaviour
• Then do the change followed by de notify api call and check on logs/tcpdump if it does really notify on API request.

Then tell us if it does what you think it should.

Regards
