What
This pull request improves error handling for Ethon instrumentation by ensuring that spans are properly closed and marked as errors when an exception occurs during the HTTP request execution, before the
completemethod is called.Why
Today, we've observed that some
ethon.clienthttp POST spans from this otel library continue unexpectedly for a long time (up to 13 hours). This has led us to believe that there are occasions where theperformmethod ran into an unhandled exception and never properly made it to thecompletemethod to close the span.
