1# $NetBSD: opt-keep-going-indirect.mk,v 1.2 2022/02/12 20:05:36 rillig Exp $ 2# 3# Tests for the -k command line option, which stops building a target as soon 4# as an error is detected, but continues building the other, independent 5# targets, as far as possible. 6# 7# History: 8# In 1993, the exit status for the option '-k' was always 0, even if a 9# direct or an indirect target failed. 10# 11# Since 2000.12.30.02.05.21, the word '(continuing)' is missing in jobs 12# mode, both for direct as well as indirect targets. 13# 14# Since 2001.10.16.18.50.12, the exit status for a direct failure in 15# compat mode is the correct 1, while jobs mode and indirect failures 16# still return the wrong exit status 0. The number of empty lines 17# between the various error messages differs between the modes, for no 18# reason. 19# 20# At 2006.11.17.22.07.39, the exit status for direct failures in both 21# modes and for indirect failures in jobs mode was fixed to the correct 22# 1. The exit status for indirect failures in compat mode is still the 23# wrong 0. On the downside, a failed indirect target in jobs mode is no 24# longer listed as "not remade because of errors". 25# 26# At 2016.08.26.23.28.39, the additional empty line for a direct failure 27# in compat mode was removed, making it consistent with a direct failure 28# in jobs mode. This left only one inconsistency, in that indirect 29# failures in jobs mode (by far the most common when building large 30# projects) did not produce any empty line. 31# 32# Since 2020.12.07.00.53.30, the exit status is consistently 1 for 33# failures in all 4 modes. 34# 35# Bugs: 36# The output in case of a failure needlessly differs between compat and 37# jobs mode. As of 2022-02-12, compat mode outputs '(continuing)' while 38# jobs mode doesn't. In compat mode, the output does not mention which 39# target failed. 40# 41# See also: 42# https://gnats.netbsd.org/49720 43 44.PHONY: all direct indirect 45 46# The 'set +e' was necessary in 2003, when the shell was run with '-e' by 47# default. 48# The 'env -i' prevents that the environment variable MAKEFLAGS is passed down 49# to the child processes. 50all: 51 @echo 'direct compat' 52 @set +e; env -i ${MAKE} -r -f ${MAKEFILE} -k direct; echo "exited $$?" 53 @echo 54 55 @echo 'direct jobs' 56 @set +e; env -i ${MAKE} -r -f ${MAKEFILE} -k direct -j1; echo "exited $$?" 57 @echo 58 59 @echo 'indirect compat' 60 @set +e; env -i ${MAKE} -r -f ${MAKEFILE} -k indirect; echo "exited $$?" 61 @echo 62 63 @echo 'indirect jobs' 64 @set +e; env -i ${MAKE} -r -f ${MAKEFILE} -k indirect -j1; echo "exited $$?" 65 @echo 66 67indirect: direct 68direct: 69 false 70 71# TODO: Mention the target that failed, maybe even the chain of targets. 72# expect: direct compat 73# expect: *** Error code 1 (continuing) 74# expect: exited 1 75 76# TODO: Add '(continuing)'. 77# expect: direct jobs 78# expect: *** [direct] Error code 1 79# expect: exited 1 80 81# TODO: Mention the target that failed, maybe even the chain of targets. 82# expect: indirect compat 83# expect: *** Error code 1 (continuing) 84# expect: exited 1 85 86# TODO: Add '(continuing)'. 87# TODO: Add 'not remade because of errors'. 88# expect: indirect jobs 89# expect: *** [direct] Error code 1 90# expect: exited 1 91
