We could rewrite it, yes, but lower effort for me today was to _reread_ it, and in doing so I realized that we disabled branch reporting seven years ago while we waited for a new GCC version; that fixed GCC version being now ancient history, I have reenabled branch coverage. One totally not funny thing is that with that enabled, lcov fails in even more interesting ways; now you need to give "inconsistent,mismatch" in LCOVFLAGS. So the whole thing is make coverage-html LCOVFLAGS="-q -j0 --ignore-errors usage,negative,inconsistent,mismatch" GENHTML_FLAGS="-q -j0 --legend --ignore-errors unmapped,corrupt,inconsistent,range" I added -j0 to both so that they run parallel processes, which should be a few second faster. In practice it may make no difference, because the real time eater is the xid_wraparound test, which lasts for 10 minutes after all the other tests have completed: # +++ tap check in src/test/modules/xid_wraparound +++ t/002_limits.pl ............ ok t/004_notify_freeze.pl ..... ok t/001_emergency_vacuum.pl .. ok t/003_wraparounds.pl ....... ok All tests successful.
