uninitialized constant ActiveRecord::ConnectionAdapters::ClosedTransaction #189

ShogunPanda · 2015-01-31T00:03:19Z

Hi. I just upgraded to em-synchrony 1.0.4.
Whenever I try to make any operation with ActiveRecord I get this error using ActiveRecord 4.2.0:

Failure/Error: Unable to find matching line from backtrace
   NameError:

Can you please fix it? :)

I would also like to see this issue solved.

This pins the Gemfile to 1.0.3 which seems to work.

est · 2015-02-28T05:03:25Z

+1 same error here. Rollback to 1.0.3 fixed the problem.

To work around igrigorik#178 and igrigorik#189.

Rollback to 1.0.3 can solve this problem.
Hope this issue to be solved soon.

vkill · 2015-05-15T05:08:31Z

rollback activerecord to 4.1.9

4.1.10 is okay too.
Eager to see this issue being fixed so that we can leverage rails 4.2's active job.

coxoc · 2015-12-25T09:20:02Z

Fixed with the following patch.(not tested in production environment)

if ::ActiveRecord::VERSION::STRING >= "4.2.0"
  module EM::Synchrony
    module ActiveRecord
      module Adapter
        def reset_transaction
          @transaction_manager = ::ActiveRecord::ConnectionAdapters::TransactionManager.new(self)
        end

        delegate :open_transactions, :current_transaction, :begin_transaction, :commit_transaction, :rollback_transaction, to: :transaction_manager
      end
    end
  end
end

igrigorik/em-synchrony#189 * em-synchrony 1.0.3 is required for ActiveRecord 3.x * em-syncrhony 1.0.4 is happy for ActiveRecord 4.x (although in some cases it is still fine with 1.0.3)

ShogunPanda · 2016-04-01T06:24:03Z

Any update on this?

dgutov · 2016-04-01T08:58:53Z

Should be fixed now with 6c88bbf (although no new release yet).

ShogunPanda · 2016-04-04T07:58:53Z

Ok, any ETA for the new release?

igrigorik · 2016-04-04T21:52:13Z

@dgutov @ShogunPanda we're overdue for a release; I can push one out. That said, I'd love to see if we can get #190 in first.

dgutov · 2016-04-04T21:59:23Z

@igrigorik From what I understand of #190, it would require a major version bump. I think it would be better to push out a backward-compatible release first.

igrigorik · 2016-04-04T22:15:00Z

@dgutov sounds reasonable. Side topic: can you please ping me on [email protected]? :)

dgutov · 2016-05-09T10:13:31Z

The new version has been released.
