runtornado: Swap deferred reload events to the default.
...
This makes no immediate reloads the default for runtornado, matching
the production configuration, and changes the development incantation
to be the one to specify the departure from the norm, with
--immediate-reloads.

tornado: Perform rolling client restarts after servers are restarted.
...
Decouple the sending of client restart events from the restarting of
the servers. Restarts use the new Tornado restart-clients endpoint to
inject "restart" events into queues of clients which were loaded from
the previous Tornado process. The rate is controlled by the
`application_server.client_restart_rate`, in clients per minute, or a
flag to `restart-clients` which overrides it. Note that a web client
will also spread its restart over 5 minutes, so artificially-slow
client restarts are generally not very necessary.
Restarts of clients are deferred to until after post-deploy hooks are
run, such that the pre- and post- deploy hooks are around the actual
server restarts, even if pushing restart events to clients takes
significant time.

2024-02-06 11:34:09 -08:00
aaf3eb514d
puppet: Allow controlling known_hosts.
...
Note that this uses `ssh-keyscan` to write in the currently-observed
host fingerprint; if DNS or network is untrusted during initial puppet
apply, this can allow attackers to write their own host key, obviating
the utility of known_hosts.
We do not view this as a likely attack mechanism, since in our
deployment the network and DNS is almost certainly trusted, and if
not, the timing attack to catch only initial configuration is likely
impossible.

puppet: Increase minimum memory for multiprocess queue workers.
...
This should give some more room for systems that are still below 4GB
of RAM to use the lower-memory multithreaded mode, which is less
likely to have OOM kills (a very bad experience).
There should be little cost, as few systems are likely allocated with
memory in this range.
