sh-flags.mk revision 1.3
1 # $NetBSD: sh-flags.mk,v 1.3 2020/12/12 12:13:12 rillig Exp $ 2 # 3 # Tests for the effective RunFlags of a shell command (run/skip, echo/silent, 4 # error check, trace), which are controlled by 12 different switches. These 5 # switches interact in various non-obvious ways. To analyze the interactions, 6 # this test runs each possible combination of these switches, for now. 7 # 8 # As soon as an interaction of switches is identified as obvious and expected, 9 # this particular interaction may be removed from the test, to focus on the 10 # remaining ones. 11 # 12 # See also: 13 # Compat_RunCommand 14 # JobPrintSpecials 15 16 all: .PHONY 17 18 opt-ignerr.yes= -i 19 opt-jobs.yes= -j1 20 opt-loud.no= -d0 # side effect: make stdout unbuffered 21 opt-loud.yes= -dl # side effect: make stdout unbuffered 22 opt-no-action.yes= -n 23 opt-silent.yes= -s 24 opt-xtrace.yes= -dx 25 tgt-always.yes= .MAKE 26 tgt-ignerr.yes= .IGNORE 27 tgt-silent.yes= .SILENT 28 cmd-always.yes= + 29 cmd-ignerr.yes= - 30 cmd-silent.yes= @ 31 32 letter.always.yes= a 33 letter.ignerr.yes= i 34 letter.jobs.yes= j 35 letter.loud.yes= l 36 letter.no-action.yes= n 37 letter.silent.yes= s 38 letter.xtrace.yes= x 39 40 .if !defined(OPT_TARGET) 41 .for opt-ignerr in no yes 42 .for opt-jobs in no yes 43 .for opt-loud in no yes 44 .for opt-no-action in no yes 45 .for opt-silent in no yes 46 # Only 'no', not 'yes', since that would add uncontrollable output from 47 # reading /etc/profile or similar files. 48 .for opt-xtrace in no 49 50 target= opt- 51 target+= ${letter.ignerr.${opt-ignerr}:U_} 52 target+= ${letter.jobs.${opt-jobs}:U_} 53 target+= ${letter.loud.${opt-loud}:U_} 54 target+= ${letter.no-action.${opt-no-action}:U_} 55 target+= ${letter.silent.${opt-silent}:U_} 56 target+= ${letter.xtrace.${opt-xtrace}:U_} 57 58 .for target in ${target:ts} 59 60 MAKE_CMD.${target}= ${MAKE} 61 MAKE_CMD.${target}+= ${opt-ignerr.${opt-ignerr}} 62 MAKE_CMD.${target}+= ${opt-jobs.${opt-jobs}} 63 MAKE_CMD.${target}+= ${opt-loud.${opt-loud}} 64 MAKE_CMD.${target}+= ${opt-no-action.${opt-no-action}} 65 MAKE_CMD.${target}+= ${opt-silent.${opt-silent}} 66 MAKE_CMD.${target}+= ${opt-xtrace.${opt-xtrace}} 67 MAKE_CMD.${target}+= -f ${MAKEFILE} 68 MAKE_CMD.${target}+= OPT_TARGET=${target} 69 MAKE_CMD.${target}+= ${target} 70 71 all: ${target} 72 ${target}: .PHONY 73 @${MAKE_CMD.${target}:M*} 74 75 .endfor 76 .endfor 77 .endfor 78 .endfor 79 .endfor 80 .endfor 81 .endfor 82 .endif 83 84 SILENT.yes= @ 85 ALWAYS.yes= + 86 IGNERR.yes= - 87 88 .if defined(OPT_TARGET) 89 .for tgt-always in no yes 90 .for tgt-ignerr in no yes 91 .for tgt-silent in no yes 92 .for cmd-always in no yes 93 .for cmd-ignerr in no yes 94 .for cmd-silent in no yes 95 96 target= ${OPT_TARGET}-tgt- 97 target+= ${letter.always.${tgt-always}:U_} 98 target+= ${letter.ignerr.${tgt-ignerr}:U_} 99 target+= ${letter.silent.${tgt-silent}:U_} 100 target+= -cmd- 101 target+= ${letter.always.${cmd-always}:U_} 102 target+= ${letter.ignerr.${cmd-ignerr}:U_} 103 target+= ${letter.silent.${cmd-silent}:U_} 104 105 .for target in ${target:ts} 106 107 ${OPT_TARGET}: .WAIT ${target} .WAIT 108 .if ${tgt-always} == yes 109 ${target}: .MAKE 110 .endif 111 .if ${tgt-ignerr} == yes 112 ${target}: .IGNORE 113 .endif 114 .if ${tgt-silent} == yes || ${OPT_TARGET:M*s*} 115 ${target}: .SILENT 116 .endif 117 118 RUNFLAGS.${target}= ${SILENT.${cmd-silent}}${ALWAYS.${cmd-always}}${IGNERR.${cmd-ignerr}} 119 .if ${OPT_TARGET:M*i*} || ${tgt-ignerr} == yes || ${cmd-ignerr} == yes 120 CMD.${target}= echo running; false 121 .else 122 CMD.${target}= echo running 123 .endif 124 125 ${target}: .PHONY 126 @+echo hide-from-output 127 @+echo hide-from-output ${target} 128 ${RUNFLAGS.${target}} ${CMD.${target}} 129 .endfor 130 131 .endfor 132 .endfor 133 .endfor 134 .endfor 135 .endfor 136 .endfor 137 .endif 138
