Subject: [PATCH 11/11] t9811-git-p4-label-import: fix pipeline negation
Date: Wed, 13 Mar 2019 13:24:19 +0100 [thread overview]
Message-ID: <20190313122419.2210-12-szeder.dev@gmail.com> (raw)
In-Reply-To: <20190313122419.2210-1-szeder.dev@gmail.com>
In 't9811-git-p4-label-import.sh' the test 'tag that cannot be
exported' runs
!(p4 labels | grep GIT_TAG_ON_A_BRANCH)
to check that the given string is not printed by 'p4 labels'. This is
problematic, because according to POSIX [1]:
"If the pipeline begins with the reserved word ! and command1 is a
subshell command, the application shall ensure that the ( operator
at the beginning of command1 is separated from the ! by one or more
<blank> characters. The behavior of the reserved word ! immediately
followed by the ( operator is unspecified."
While most common shells still interpret this '!' as "negate the exit
code of the last command in the pipeline", 'mksh/lksh' don't and
interpret it as a negative file name pattern instead. As a result
they attempt to run a command made up of the pathnames in the current
directory (it contains a single directory called 'main'), which, of
course, fails the test.
We could fix it simply by adding a space between the '!' and '(', but
instead let's fix it by removing the unnecessary subshell.
