Subject: [PATCH] config: Make sure profile.sh succeeds with set -e and set -o pipefail
Date: Tue, 26 Mar 2024 21:49:48 +0100 [thread overview]
Message-ID: <20240326204948.794765-1-mark@klomp.org> (raw)
profile.sh might fail with set -o pipefail because:
cat /dev/null "${prefix}/etc/debuginfod"/*.urls 2>/dev/null | tr '\n' ' '
might fail when there isn't an *.urls file the first command in the
pipe fails (the 2>/dev/null is there to hide that failure).
This can be fixed by adding || echo -n "" at the end.
This works because echo -n "" produces the empty string which is what
the script expects when the command would fail.
Also add a new testcase that runs profile.sh with bout set -e
and set -o pipefail.
* config/profile.sh.in: Add || echo -n "" at end of pipe.
* tests/run-debuginfod-client-profile.sh: New test.
* tests/Makefile.am (TESTS): Add run-debuginfod-client-profile.sh.
(EXTRA_DIST): Likewise.
