Can you elaborate with an example? My understanding was that
test_must_fail is only for running git. If a test is running perl and
wants to check its exit code, the test is supposed to use !, not
test_must_fail.
t/README backs me up:
- use '! git cmd' when you want to make sure the git command exits
with failure in a controlled way by calling "die()". Instead,
use 'test_must_fail git cmd'. This will signal a failure if git
dies in an unexpected way (e.g. segfault).
On the other hand, don't use test_must_fail for running regular
platform commands; just use '! cmd'. We are not in the business
of verifying that the world given to us sanely works.
So I don't consider the initial issue you raised a test issue at all!
It's a bug in the git commands, and a fix for it should not be
specific to the test suite.
And now it sounds like there is a second issue: the test suite is
overusing test_must_fail in some context and that needs to be fixed as
well.
Thanks,
Jonathan
