commit cb3acb5f6a878e9b34f60b6d9bb2bacb5194a3b8 Author: Rusty Bird <rustybird@openmailbox.org> Date: Thu Dec 8 17:18:12 2016 +0000 Bug 20147: (re-)dzip.sh: various improvements - Don't ignore errors (except unzip exit status 1 or 2) - Quote $@ and $1 - Work with absolute filenames and filenames starting with a dash - Pass many files per chmod invocation (much faster) - Pass $UNZIPOPTS, like $ZIPOPTS - Reuse dzip.sh in re-dzip.sh The (re)generated zip files are identical. --- gitian/build-helpers/dzip.sh | 17 ++++++++--------- gitian/build-helpers/re-dzip.sh | 23 ++++++++++------------- 2 files changed, 18 insertions(+), 22 deletions(-) diff --git a/gitian/build-helpers/dzip.sh b/gitian/build-helpers/dzip.sh index 5772c8b..64fcdca 100755 --- a/gitian/build-helpers/dzip.sh +++ b/gitian/build-helpers/dzip.sh @@ -1,14 +1,13 @@ -#!/bin/sh +#!/bin/sh -e # Crappy deterministic zip wrapper export LC_ALL=C -ZIPFILE=$1 +ZIPFILE=${1:?} shift -[ -n "$REFERENCE_DATETIME" ] && \ - find $@ -exec touch --date="$REFERENCE_DATETIME" {} \; - -find $@ -executable -exec chmod 700 {} \; -find $@ ! -executable -exec chmod 600 {} \; - -find $@ | sort | zip $ZIPOPTS -X -@ "$ZIPFILE" +if [ -n "$REFERENCE_DATETIME" ]; then + find "$@" -exec touch --date="$REFERENCE_DATETIME" -- {} + +fi +find "$@" -executable -exec chmod 700 {} + +find "$@" ! -executable -exec chmod 600 {} + +find "$@" | sort | zip $ZIPOPTS -X -@ "$ZIPFILE" diff --git a/gitian/build-helpers/re-dzip.sh b/gitian/build-helpers/re-dzip.sh index 27828e9..8e8abbf 100755 --- a/gitian/build-helpers/re-dzip.sh +++ b/gitian/build-helpers/re-dzip.sh @@ -1,17 +1,14 @@ -#!/bin/sh +#!/bin/sh -e # Crappy deterministic zip repackager export LC_ALL=C -ZIPFILE=`basename $1` +ZIPFILE_BASENAME=$(basename -- "${1:?}") +TEMPDIR=tmp-re-dzip-$$ +RE_DZIP=$(readlink -f -- "$(which -- "$0")") +PATH=$PATH:$(dirname "$RE_DZIP") -mkdir tmp_dzip -cd tmp_dzip -unzip ../$1 -[ -n "$REFERENCE_DATETIME" ] && \ - find . -exec touch --date="$REFERENCE_DATETIME" {} \; -find . -executable -exec chmod 700 {} \; -find . ! -executable -exec chmod 600 {} \; -find . | sort | zip $ZIPOPTS -X -@ $ZIPFILE -mv $ZIPFILE ../$1 -cd .. -rm -rf tmp_dzip +mkdir "$TEMPDIR" +unzip $UNZIPOPTS -d "$TEMPDIR" -- "$1" || [ $? -lt 3 ] +(cd "$TEMPDIR"; dzip.sh ./"$ZIPFILE_BASENAME" .) +mv -- "$TEMPDIR"/"$ZIPFILE_BASENAME" "$1" +rm -rf "$TEMPDIR"
