The branch stable/13 has been updated by arichardson: URL: https://cgit.FreeBSD.org/src/commit/?id=6a68c094ed1be74fd5556ac716c8bb12f3564f82 commit 6a68c094ed1be74fd5556ac716c8bb12f3564f82 Author: Alex Richardson <arichardson@FreeBSD.org> AuthorDate: 2021-03-01 18:49:31 +0000 Commit: Alex Richardson <arichardson@FreeBSD.org> CommitDate: 2021-03-17 12:23:57 +0000 ptrace_test: Add more debug output on test failures Mostly automatic, using `CHILD_REQUIRE\(([^|&\n]*) ==` -> `CHILD_REQUIRE_EQ_INT($1,` `ATF_REQUIRE\(([^|&\n]*) ==` -> `REQUIRE_EQ_INT($1,` followed by git-clang-format -f and then manually checking ones that contain ||/&&. Test Plan: Still getting the same failure but now it prints `psr.sr_error (0) == EBADF (9) not met` instead of just failing without printing the values.
