April 6 2019 | Multisection: When You Need to Bisect More Than Once | Back Next |
We needed new tool which would:
Apply principle of bisectioning to reduce number of commits to be run
Focus on differences in entire test output rather than just test result (PASS/FAIL)
Has output of lib/locale.t at commit N changed from commit N - 1?
Identifying "First FAIL" not sufficient
We know lib/locale.t failed in at least 2 different ways
Need to identify each commit at which test output changed
After we identify first change in test output, must repeatedly bisect
