It's expected that this will lead to unwanted behavior, and needs widespread testing. It's desirable to commit this for a few reasons: - there's no reason we can't do our own error checking for code that we write. - it avoids the need for ||true hacks scattered about in the code. - it makes us immune to upstream changes in exit codes (FS#28248) Signed-off-by: Dave Reisner <dreisner@archlinux.org> --- Allan, just making sure we're on the same page -- this _will_ cause breakage, and the next patch in this series addresses one specific case. I figure getting this patch in now gives us "ample time" to uncover and fix all these before the next release. scripts/makepkg.sh.in | 47 +++++++++++++++++++++++------------------------ 1 files changed, 23 insertions(+), 24 deletions(-) diff --git a/scripts/makepkg.sh.in b/scripts/makepkg.sh.in index f0a2252..61c95af 100644 --- a/scripts/makepkg.sh.in +++ b/scripts/makepkg.sh.in @@ -1,4 +1,4 @@ -#!/bin/bash -e +#!/bin/bash # # makepkg - make packages compatible for use with pacman # @configure_input@ @@ -430,13 +430,10 @@ run_pacman() { check_deps() { (( $# > 0 )) || return 0 - # Disable error trap in pacman subshell call as this breaks bash-3.2 compatibility - # Also, a non-zero return value is not unexpected and we are manually dealing them - set +E local ret=0 local pmout - pmout=$(run_pacman -T "$@") || ret=$? - set -E + pmout=$(run_pacman -T "$@") + ret=$? if (( ret == 127 )); then #unresolved deps echo "$pmout" @@ -469,13 +466,7 @@ handle_deps() { fi # we might need the new system environment - # avoid triggering the ERR trap and exiting - set +e - local restoretrap=$(trap -p ERR) - trap - ERR source /etc/profile &>/dev/null - eval $restoretrap - set -e return $R_DEPS_SATISFIED } @@ -867,6 +858,23 @@ error_function() { exit 2 # $E_BUILD_FAILED } +run_function_safe() { + local restoretrap + + set -e + set -E + + restoretrap=$(trap -p ERR) + trap 'error_function $pkgfunc' ERR + + run_function "$1" + + eval $restoretrap + + set +E + set +e +} + run_function() { if [[ -z $1 ]]; then return 1 @@ -892,7 +900,6 @@ run_function() { local shellopts=$(shopt -p) local ret=0 - local restoretrap if (( LOGGING )); then local fullver=$(get_full_version) local BUILDLOG="${startdir}/${pkgbase}-${fullver}-${CARCH}-$pkgfunc.log" @@ -914,18 +921,12 @@ run_function() { tee "$BUILDLOG" < "$logpipe" & local teepid=$! - restoretrap=$(trap -p ERR) - trap 'error_function $pkgfunc' ERR $pkgfunc &>"$logpipe" - eval $restoretrap wait $teepid rm "$logpipe" else - restoretrap=$(trap -p ERR) - trap 'error_function $pkgfunc' ERR $pkgfunc 2>&1 - eval $restoretrap fi # reset our shell options eval "$shellopts" @@ -943,11 +944,11 @@ run_build() { [[ -d /usr/lib/ccache/bin ]] && export PATH="/usr/lib/ccache/bin:$PATH" fi - run_function "build" + run_function_safe "build" } run_check() { - run_function "check" + run_function_safe "check" } run_package() { @@ -958,7 +959,7 @@ run_package() { pkgfunc="package_$1" fi - run_function "$pkgfunc" + run_function_safe "$pkgfunc" } tidy_install() { @@ -1973,8 +1974,6 @@ for signal in TERM HUP QUIT; do trap "trap_exit \"$(gettext "%s signal caught.
