I've incorporated changes from #1575 into this PR, so it should have both changes. The only thing missing is gemfile updates, which I'm doing now. |
lib/ddtrace/metrics.rb

Note: In #1575 we had discussed and decided to remove this, and instead just make ddtrace treat 5.0.0, 5.0.1 and 5.1.0 as "incompatible" versions and outright not use them. See the discussion in the PR for details.

I thought it wasn't a good idea to make it incompatible, but I now agree with metrics being missing for safety. Changes applied.

This PR uses the new
single_threadmode fordogstatsd-rubyclients instantiated byddtrace.This allows us to have the benefits of batch metric submission of
dogstatsd-ruby, without memory issues we've seen with the5.xreleases.This PR adds a new test combination for the affected
5.xversionsdogstatsd-ruby, to ensure we are informing users that they should use a different version of the library in order to have a more stable environment.
