Motivation
The W3C Trace Context mutation rules require unmodified
tracestatemembers to retain their order.Thanks to @zacharycmontoya for identifing this coverage gap here.
Changes
Add an end-to-end regression using
dd=s:1,foo=bar,ot=rv:6e6d1a75832a2f,something=elseand assert the raw downstream suffix remainsfoo=bar,ot=rv:6e6d1a75832a2f,something=else.Existing tests verify parsed
dd,ot, and vendor values. This raw comparisonis complementary because parsed key/value checks cannot detect reordering.
