Node.js agent v4.2.0

June 19, 2018Download

Added an option for using the finally method on promises for instrumentation.
The promise instrumentation would use Promise#finally if available. This change is in response to Node v10 promises calling then inside their finally method, which caused infinite recursion in the agent's promise instrumentation.
Added seen/sent/dropped supportability metrics for all event collections.

Refactored harvest cycle into separate class.
This refactoring eases managing harvested data and re-merging unharvested values on failure.
No longer download gcc on test suites that do not require it.

Updated WebFrameworkShim to handle arrays of routes when wrapping middleware mounters.
Previously, a transaction that hit a shared middleware (eg, app.use(['/one', '/two'], ...)) would always be tagged with <unknown> in its name, due to the agent not interpreting arrays of paths. Now transaction names will include all paths for a shared middleware, comma-delimited, followed by the current route ('WebTransaction/Expressjs/GET//one,/two/one').
