The tests that used the "try_repo" helper wanted to check whether git commands invoked therein would emit anything on stderr. To do this they invoked the function and redirected the stderr to a "message" file. In 58275069288 (t1510-repo-setup: mark as untraceable with '-x', 2018-02-24) these were made to use "test_untraceable" introduced in 5fc98e79fc0 (t: add means to disable '-x' tracing for individual test scripts, 2018-02-24). It is better to have the "try_repo" function itself start with a "test_when_finished 'rm stderr'", and then redirect the stderr output from git commands it invokes via its helpers to a "stderr" file. This means that if we have a failure it'll be closer to the source of the problem, and most importantly isn't incompatible with "-x" on shells that aren't "bash". We also need to split those tests that had two "try_repo" invocations into different tests, which'll further help to narrow down any potential failures. This wasn't strictly necessary (an artifact of the use of "test_when_finished"), but the pattern enforces better test hygiene. The functions it calls might change directories, so we pass an absolute "$stderr_log_path" around. We also need to change a "$(pwd)" to "$PWD" in test_repo(), on e.g. "dash" that interpolation will be traced and part of the "2>>" redirection. 1. https://lore.kernel.org/git/YbMiK1wHzBfYvK2a@coredump.intra.peff.net/ Signed-off-by: Ævar Arnfjörð Bjarmason --- t/t1510-repo-setup.sh | 85 +++++++++++++++++++++---------------------- 1 file changed, 42 insertions(+), 43 deletions(-) diff --git a/t/t1510-repo-setup.sh b/t/t1510-repo-setup.sh index 591505a39c0..fc94d8b49be 100755 --- a/t/t1510-repo-setup.sh +++ b/t/t1510-repo-setup.sh @@ -40,9 +40,6 @@ A few rules for repo setup: prefix is NULL.
