The 🐳 Workspace (ubuntu:latest) job on main (run 38879556215, 1b36ef6120)
failed test-unit-python in the hook's second make test:
AssertionError: Regex didn't match: '^ localhost=ok/\d+ms$'
not found in ' localhost=ok/-1612931482679767779ms'
ubuntu:latest is Ubuntu 26.04, whose date is uutils coreutils. uutils
0.7.0 ignores the field width in %3N and prints all nine nanosecond
digits, so `date +%s%3N` yields a 19-digit value instead of epoch
milliseconds. Against main's sampler, uutils 0.7.0 date reports
localhost=ok/7081859ms, and an unpadded nanosecond value turns the
difference negative.
answer_once now takes both timestamps from /proc/uptime, which the
kernel prints with two decimals whatever date the image ships. The
sampler already reads /proc/net/udp, so it was Linux-only before. The
resolution is 10 ms; the same probe reports 10 to 20 ms with uutils
date on PATH.
The new test puts a date on PATH that does not understand %3N; main's
sampler dies on it, the fixed one does not call date for the latency.
