[LU-4824] lfs find should continue after errors

Related — Mon, 18 Aug 2014 15:56:36 +0000

A user has noticed that 'lfs find' stops as soon as it encounters an error, such as EACCES. The regular find command just notes the failure but continues on, returning a non-zero exit code at the end.

# mkdir -p $LUSTREDIR/{dirb,dirc}
# touch $LUSTREDIR/{dirb,dirc}/file1
# sudo chown root:root $LUSTREDIR/dirb
# sudo chmod 700 $LUSTREDIR/dirb
# find $LUSTREDIR -name file1
find: `/lustre/f1/Matthew.Ezell/testdir/dirb': Permission denied
/lustre/f1/Matthew.Ezell/testdir/dirc/file1
# echo $?
1
# lfs find $LUSTREDIR -name file1
llapi_semantic_traverse: Failed to open '/lustre/f1/Matthew.Ezell/testdir/dirb': Permission denied (13)
error: find failed for file1.
# echo $?
22

I created a patch that changes the behavior to the following:

# /tmp/usr/bin/lfs find $LUSTREDIR -name file1
llapi_semantic_traverse: Failed to open '/lustre/f1/Matthew.Ezell/testdir/dirb': Permission denied (13)
/lustre/f1/Matthew.Ezell/testdir/dirc/file1
error: find failed for file1.
# echo $?
1

If you would like, I could change my patch to return EINVAL as it previously did.
