Subject: [PATCH 2/2] t9402-git-cvsserver-refs: don't check the stderr of a subshell
Date: Thu,  8 Mar 2018 13:38:44 +0100
Message-ID: <20180308123844.15163-3-szeder.dev@gmail.com> (raw)
In-Reply-To: <20180308123844.15163-1-szeder.dev@gmail.com>

Four 'cvs diff' related tests in 't9402-git-cvsserver-refs.sh' fail
when the test script is run with '-x' tracing (and using a shell other
than a Bash version supporting BASH_XTRACEFD).  The reason for those
failures is that the tests check the emptiness of a subshell's stderr,
which includes the trace of commands executed in that subshell as
well, throwing off the emptiness check.

Save the stdout and stderr of the invoked 'cvs' command instead of the
whole subshell, so the latter remains free from tracing output.  (Note
that changing how stdout is saved is only done for the sake of
consistency, it's not necessary for correctness.)

After this change t9402 passes with '-x', even when running with
/bin/sh.
