There's been past attempts to add a "set -o pipefail" test mode. I suspect it can't be done in any sane way the way it works in bash now. See 6/6 for details. This series makes it work because I patched it to work sanely in bash itself when it comes to SIGPIPE. I'm partially submitting this so I can prod the bash maintainer with a link to this thread. But also because even though you need to patch your bash to benefit from this new test mode, it doesn't break anything for anyone who doesn't have the patch (we guard it with a detection for the sane behavior), and at the very least 4/6 (or maybe just to 2/6) are generally sane fixes even without the rest. 1. https://lore.kernel.org/git/cover.1573779465.git.liu.denton@xxxxxxxxx/ Ævar Arnfjörð Bjarmason (6): test-lib: add tests for test_might_fail test-lib: add ok=* support to test_might_fail test_lib: allow test_{must,might}_fail to accept non-git on "sigpipe" tests: use "test_might_fail ok=sigpipe grep" when appropriate tests: split up bash detection library tests: add a "set -o pipefail" for a patched bash t/README | 6 +++++ t/lib-bash-detection.sh | 8 +++++++ t/lib-bash.sh | 4 +++- t/t0000-basic.sh | 38 ++++++++++++++++++++++++++++++ t/t0005-signals.sh | 4 ++-- t/t0090-cache-tree.sh | 2 +- t/t5000-tar-tree.sh | 2 +- t/t5703-upload-pack-ref-in-want.sh | 2 +- t/t9151-svn-mergeinfo.sh | 6 ++--- t/t9902-completion.sh | 5 ++++ t/test-lib-functions.sh | 24 ++++++++++++++++++- t/test-lib.sh | 29 +++++++++++++++++++++++ 12 files changed, 120 insertions(+), 10 deletions(-) create mode 100644 t/lib-bash-detection.sh -- 2.29.2.222.g5d2a92d10f8
