Hi Michael, thanks for the report. I can indeed confirm this is a bug. For the moment, I have added a test case exposing it (see patch below). I hope to be able to fix it for Automake 1.12.5. Thanks, Stefano ---- 8< ---- 8< ---- 8< ---- 8< ---- 8< ---- 8< ---- 8< ---- 8< ---- >From a8eac4978d3ba21da0e1ee3ce643788383997de0 Mon Sep 17 00:00:00 2001 Message-Id: <a8eac4978d3ba21da0e1ee3ce643788383997de0.1349252144.git.stefano.lattar...@gmail.com> From: Stefano Lattarini <stefano.lattar...@gmail.com> Date: Tue, 2 Oct 2012 21:27:28 +0200 Subject: [PATCH] subdirs: don't return false positives for the '-k' option's presence This change is related to automake bug#12554. The current implementation of the code descending into $(SUBDIRS) entries uses the following snippet to decide whether make is running with the '-k' a.k.a. '--keep-going' option, and thus whether a failure in a subdirectory should prevent the descent in the following ones: fail= failcom='exit 1'; \ for f in x $$MAKEFLAGS; do \ case $$f in \ *=* | --[!k]*);; \ *k*) failcom='fail=yes';; \ esac; \ done It's clear that the second pattern in the 'case' construct can possibly match false positives, for examples in these two cases: make check TESTS="x.test k.test" make -I /usr/local/kool-fragments which are somewhat unusual, but not invalid. So we need a more resilient implementation, as we did for the detection of the '-n' flag. But alas, such an implementation seems quite tricky to obtain in portable make. So for the moment we content ourselves with exposing the bug, with the hope of being able to fix it at a later date. If not in mainline Automake, at least in Automake-NG. * t/subdir-keep-going-pr12554.sh: New test. * t/list-of-tests.mk (handwritten_TESTS, XFAIL_TESTS): Add it. * THANKS: Update Reported-by: Michael Daniels <mdani...@rim.com> Signed-off-by: Stefano Lattarini <stefano.lattar...@gmail.com> --- THANKS | 1 + t/list-of-tests.mk | 2 ++ t/subdir-keep-going-pr12554.sh | 58 ++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 61 insertions(+) create mode 100755 t/subdir-keep-going-pr12554.sh diff --git a/THANKS b/THANKS index 88f539c..15a3d8e 100644 --- a/THANKS +++ b/THANKS @@ -252,6 +252,7 @@ Maxim Sinev g...@goods.ru Maynard Johnson mayna...@us.ibm.com Merijn de Jonge m.de.jo...@cwi.nl Michael Brantley michael-brant...@deshaw.com +Michael Daniels mdani...@rim.com Michael Hofmann mho...@googlemail.com Michael Ploujnikov plo...@gmail.com Michel de Ruiter mdrui...@cs.vu.nl diff --git a/t/list-of-tests.mk b/t/list-of-tests.mk index b3ff6b2..1bfd056 100644 --- a/t/list-of-tests.mk +++ b/t/list-of-tests.mk @@ -41,6 +41,7 @@ t/pr8365-remake-timing.sh \ t/lex-subobj-nodep.sh \ t/remake-am-pr10111.sh \ t/remake-m4-pr10111.sh \ +t/subdir-keep-going-pr12554.sh \ t/tags-pr12372.sh \ t/txinfo5.sh \ $(perl_fake_XFAIL_TESTS) @@ -1023,6 +1024,7 @@ t/subdir-with-slash.sh \ t/subdir-subsub.sh \ t/subdir10.sh \ t/subdir-distclean.sh \ +t/subdir-keep-going-pr12554.sh \ t/subdirbuiltsources.sh \ t/subobj.sh \ t/subobj2.sh \ diff --git a/t/subdir-keep-going-pr12554.sh b/t/subdir-keep-going-pr12554.sh new file mode 100755 index 0000000..59bd7d0 --- /dev/null +++ b/t/subdir-keep-going-pr12554.sh @@ -0,0 +1,58 @@ +#! /bin/sh +# Copyright (C) 2012 Free Software Foundation, Inc. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
