this is a crazy-complex solution for a very simple problem: removing certain lines from the output without chaning the exit-status normally I'd not do this, but it has been lots of fun and a great learning experience :)
-
sed does not support | without -r
-
grep changes 0 exitstatus to 1 if nothing matches
-
sed changes 1 exitstatus to 0
-
pipefail makes pipe fail with exitstatus of first failed command
-
pipefail is not supported in (zsh)
-
defining a new rake task like silence_schema would force users to load parallel_tests in test env
-
do not use ' since
run_in_parallel
uses them to quote stuff -
simple system “set -o pipefail” returns nil even though set -o pipefail exists with 0
# File lib/parallel_tests/tasks.rb, line 30 def suppress_output(command, ignore_regex) activate_pipefail = "set -o pipefail" remove_ignored_lines = %Q{(grep -v "#{ignore_regex}" || test 1)} if system("#{activate_pipefail} && test 1") "#{activate_pipefail} && (#{command}) | #{remove_ignored_lines}" else command end end
