fix: Test failures on Bash 5.3 macOS (nix-shell) by tricktron · Pull Request #913 · TypedDevs/bashunit

tricktron · 2026-07-28T18:49:57Z

Background

Closes#912.

I first stumbled on this issue in NixOS/nixpkgs#543029.

If merged we can update and simplify the bashunit derivation in nixpkgs and all tests will pass even in the sandbox on darwin.

Changes

render_diff didn't bypass external diff tools. Anyone with e.g. difftastic got broken output (2 failures)
shell_time() and one acceptance test used LC_ALL=C inside $(), which segfaults on Bash 5.3 macOS. I removed since it was unnecessary in both places (5 failures).

Checklist

I updated the CHANGELOG.md to reflect the new feature or fix
I updated the documentation to reflect the changes

Users with diff.external configured (e.g. difftastic) get broken diff output because git delegates to the external tool, which ignores --word-diff and produces a different format.

Bash 5.3 on macOS segfaults (exit 139) when LC_ALL is set inside a command substitution that reads the magic EPOCHREALTIME variable. Besides, force the console_results_test to use the perl clock path on Bash 5+.

Bash 5.3 on macOS segfaults when LC_ALL=C is used as a temporary env prefix inside $() command substitutions. The LC_ALL=C LANG=C was unnecessary here: the asserted strings ('failed', 'Error') come from bashunit's own output, not locale-dependent messages.

/tmp is not writable inside the nix sandbox on darwin, causing all init tests to fail with 'Permission denied'.

The JUnit time reads still used a bare LC_ALL=C awk prefix, the same form that segfaults inside $() on Bash 5.3.9 macOS. C is required here (it keeps awk's radix a dot in the XML), so pass it through env instead of removing it.

Nothing guarded either fix: no CI job runs Bash 5.3 macOS or sets diff.external, so both regressions could return unnoticed.

Chemaclass

Nice catch, and thanks for the clear reproducer in #912. That made both bugs easy to confirm. You got here first, so I'm merging yours and closing my #914.

I pushed a few small things on top so you don't have to round-trip:

src/reports.sh had the same LC_ALL=C prefix in its two JUnit time reads, so --report-junit would still crash on Bash 5.3. There the C locale is actually doing something (it keeps awk printing 1.234 and not 1,234), so I used env LC_ALL=C awk instead of removing it.
A test for each fix. CI can't catch these on its own: no runner has diff.external set, and none runs Bash 5.3 on macOS. Both tests fail without your changes.
A short comment next to each removal so nobody puts the prefix back, plus the CHANGELOG entries moved to the top of Fixed with the (#912) link.

Dropping LC_ALL=C LANG=C from the acceptance test was the right call. Those assertions only look at bashunit's own output, and the Spanish/Brazilian/Japanese jobs run the acceptance tests too, so they'd have told us otherwise.

All green here on macOS Bash 3.2 (make test, --parallel, make sa, make lint). Thanks again!

test(compat): cover the external differ and the locale prefix
4bc1d31
Nothing guarded either fix: no CI job runs Bash 5.3 macOS or sets diff.external, so both regressions could return unnoticed.

fix(runner): bypass external diff tools in word-diff rendering
b87d349
Users with diff.external configured (e.g. difftastic) get broken diff output because git delegates to the external tool, which ignores --word-diff and produces a different format.

fix(runner): avoid SIGSEGV in shell_time on Bash 5.3 macOS
b7c92c2
Bash 5.3 on macOS segfaults (exit 139) when LC_ALL is set inside a command substitution that reads the magic EPOCHREALTIME variable. Besides, force the console_results_test to use the perl clock path on Bash 5+.

docs: add changelog entries for diff and LC_ALL fixes
4d9e272

fix(test): use $TMP_DIR for init test log instead of /tmp
01b62b5
/tmp is not writable inside the nix sandbox on darwin, causing all init tests to fail with 'Permission denied'.
