Subject: [PATCH v4 2/8] test-lib: extract Bash version check for '-x' tracing
Date: Sat, 5 Jan 2019 02:08:53 +0100 [thread overview]
Message-ID: <20190105010859.11031-3-szeder.dev@gmail.com> (raw)
In-Reply-To: <20190105010859.11031-1-szeder.dev@gmail.com>
One of our test scripts, 't1510-repo-setup.sh' [1], still can't be
reliably run with '-x' tracing enabled, unless it's executed with a
Bash version supporting BASH_XTRACEFD (since v4.1). We have a lengthy
condition to check the version of the shell running the test script,
and disable tracing if it's not executed with a suitable Bash version
[2].
Move this check out from the option parsing loop, so other options can
imply '-x' by setting 'trace=t', without missing this Bash version
check.
[1] 5827506928 (t1510-repo-setup: mark as untraceable with '-x',
2018-02-24)
[2] 5fc98e79fc (t: add means to disable '-x' tracing for individual
test scripts, 2018-02-24)
