Hi, I''ve just got a quick question.
How come
ActiveRecord::ConnectionAdapters::ConnectionHandler#verify_active_connections!
is marked with :nodoc: ?
I understand that this is used internally (depending upon an
application''s
configuration?) on every request (?) to clear out old, stale database
connections. All this to prevent the old, classic "MySQL server has gone
away..." types of exceptions with applications that sometimes see very
little usage.
However, from my searching in this (and the Ruby on Rails: Talk) list(s),
I''m also under the impression that someone using ActiveRecord without
rails
might have to call this manually. In my case, I''m setting up a resque
(https://github.com/defunkt/resque) system and might have my worker(s) use
ActiveRecord but _not_ the full rails environment. I might have a worker go
long stretches without any action, giving me stale connections in my
connection pool. To avoid any problems, I found a gem,
resque-ensure-connected
(https://github.com/wireframe/resque-ensure-connected) that apparently just
calls #verify_active_connections! in order to solve this problem.
So, why do I care? Because while reading the source of the
resque-ensure-connected gem I realized it''s solution literally just
comes
down to simply calling #verify_active_connections!. I was curious about this
method and tried to look it up in the docs. It wasn''t there. I
don''t like
using stuff that relies on unpublished "internals" in case said
internal
method/API changes on me down the line.
So, is this a stable, public API method? If so, may we allow it to be
documented please?
If not, what should someone in my situation use?
Thanks for your time!
