It can accelerate this long step by 5 in my tests. xargs reports a global error if one of the process has an error. Running a shell function with xargs requires to export it with -f, and that is a specific capability of bash. Signed-off-by: Thomas Monjalon Tested-by: Ferruh Yigit --- v2: - find dump2 inside the function - force bash because of export -f v3: - revert to POSIX sh - use POSIX eval instead of export -f (issues on Ubuntu) --- devtools/check-abi.sh | 21 +++++++++++++-------- devtools/gen-abi.sh | 5 +++-- 2 files changed, 16 insertions(+), 10 deletions(-) diff --git a/devtools/check-abi.sh b/devtools/check-abi.sh index c583eae2fd..d58c867c60 100755 --- a/devtools/check-abi.sh +++ b/devtools/check-abi.sh @@ -34,19 +34,18 @@ else ABIDIFF_OPTIONS="$ABIDIFF_OPTIONS --headers-dir2 $incdir2" fi -error= -for dump in $(find $refdir -name "*.dump"); do +export diff_func='run_diff() { + dump=$1 + newdir=$2 name=$(basename $dump) dump2=$(find $newdir -name $name) if [ -z "$dump2" ] || [ ! -e "$dump2" ]; then echo "Error: cannot find $name in $newdir" >&2 - error=1 - continue - fi + return 1 + fi; abidiff $ABIDIFF_OPTIONS $dump $dump2 || { abiret=$? - echo "Error: ABI issue reported for 'abidiff $ABIDIFF_OPTIONS $dump $dump2'" >&2 - error=1 + echo "Error: ABI issue reported for abidiff $ABIDIFF_OPTIONS $dump $dump2" >&2 echo if [ $(($abiret & 3)) -ne 0 ]; then echo "ABIDIFF_ERROR|ABIDIFF_USAGE_ERROR, this could be a script or environment issue." >&2 @@ -58,7 +57,13 @@ for dump in $(find $refdir -name "*.dump"); do echo "ABIDIFF_ABI_INCOMPATIBLE_CHANGE, this change breaks the ABI." >&2 fi echo + return 1 } -done +}' + +error= +find $refdir -name "*.dump" | +xargs -n1 -P0 sh -c 'eval "$diff_func"; run_diff $0 '$newdir || +error=1 [ -z "$error" ] || [ -n "$warnonly" ] diff --git a/devtools/gen-abi.sh b/devtools/gen-abi.sh index f15a3b9aaf..61f7510ea1 100755 --- a/devtools/gen-abi.sh +++ b/devtools/gen-abi.sh @@ -22,5 +22,6 @@ for f in $(find $installdir -name "*.so.*"); do fi libname=$(basename $f) - abidw --out-file $dumpdir/${libname%.so*}.dump $f -done + echo $dumpdir/${libname%.so*}.dump $f +done | +xargs -n2 -P0 abidw --out-file -- 2.39.0
