Thread: https://gitlist.dev/t/66104 ## Kenneth Lorber, 2026-08-03 00:41 Subject: [PATCH 0/1] t7528: fix failure under csh Message-ID: <20260803004105.36913-1-keni@his.com> ``` The test suite fails at t7528 when run in an account with tcsh as the login shell due to $SHELL being "/bin/tcsh"; similar behaviour is expected under other csh-like shells. From ssh-agent(1): -s Generate Bourne shell commands on stdout. This is the default if SHELL does not look like it's a csh style of shell. This patch explicitly tells ssh-agent to use Bourne shell syntax, thus removing a spurious test failure for users with csh style shells. An alternative change would be to have test-lib.sh clear $SHELL; this was rejected as potentially hiding additional similar errors. There are no such additional errors evident currently. No additional tests are added as the error is in the setup for testing, not an error in git itself.

SHELL is defined by POSIX as "a pathname of the user's preferred command language interpreter." When we're running the testsuite, we don't care what that is and always want a POSIX sh-compatible output, so using `-s` is the right thing. I also don't see any other instances of `ssh-agent` in the codebase, so this looks like the only place we need to fix. -- brian m. carlson (they/them) Toronto, Ontario, CA ``` ## Junio C Hamano, 2026-08-03 14:42 Subject: Re: [PATCH 1/1] t7528: fix failure under csh Message-ID: In-Reply-To: ``` "brian m. carlson" writes: >> @@ -82,7 +82,7 @@ test_expect_success GPGSSH 'create signed commits' ' >> test_expect_success GPGSSH 'sign commits using literal public keys with ssh-agent' ' >> test_when_finished "test_unconfig commit.gpgsign" && >> test_config gpg.format ssh && >> - eval $(ssh-agent -T || ssh-agent) && >> + eval $(ssh-agent -T -s || ssh-agent -s) && >> test_when_finished "kill ${SSH_AGENT_PID}" && >> test_when_finished "test_unconfig user.signingkey" && >> mkdir tmpdir && > > This seems reasonable.

Thanks for being careful. Will queue. ```
