# $NetBSD: opt-keep-going-indirect.mk,v 1.3 2024/04/02 15:05:15 rillig Exp $
#
# Tests for the -k command line option, which stops building a target as soon
# as an error is detected, but continues building the other, independent
# targets, as far as possible.
#
# History:
# In 1993, the exit status for the option '-k' was always 0, even if a
# direct or an indirect target failed.
#
# Since 2000.12.30.02.05.21, the word '(continuing)' is missing in jobs
# mode, both for direct as well as indirect targets.
#
# Since 2001.10.16.18.50.12, the exit status for a direct failure in
# compat mode is the correct 1, while jobs mode and indirect failures
# still return the wrong exit status 0. The number of empty lines
# between the various error messages differs between the modes, for no
# reason.
#
# At 2006.11.17.22.07.39, the exit status for direct failures in both
# modes and for indirect failures in jobs mode was fixed to the correct
# 1. The exit status for indirect failures in compat mode is still the
# wrong 0. On the downside, a failed indirect target in jobs mode is no
# longer listed as "not remade because of errors".
#
# At 2016.08.26.23.28.39, the additional empty line for a direct failure
# in compat mode was removed, making it consistent with a direct failure
# in jobs mode. This left only one inconsistency, in that indirect
# failures in jobs mode (by far the most common when building large
# projects) did not produce any empty line.
#
# Since 2020.12.07.00.53.30, the exit status is consistently 1 for
# failures in all 4 modes.
#
# Bugs:
# The output in case of a failure needlessly differs between compat and
# jobs mode. As of 2022-02-12, compat mode outputs '(continuing)' while
# jobs mode doesn't. In compat mode, the output does not mention which
# target failed.
#

# The 'set +e' was necessary in 2003, when the shell was run with '-e' by
# default.
