Reviewed-by: Amir Goldstein Signed-off-by: Chengguang Xu --- v1->v2: - Call _get_block_size to get fs block size. - Add comment for test space requirement. - Print meaningful error message when copy-up fail. - Adjust random hole range to 1M~5M. - Fix typo. v2->v3: - Fix space requiremnt for test. - Add more descriptions for test files and hole patterns. - Define well named variables to replace unexplained numbers. - Fix random hole algorithm to what Amir suggested. - Adjust iosize to start from 1K. - Remove from quick test group. tests/overlay/066 | 130 ++++++++++++++++++++++++++++++++++++++++++ tests/overlay/066.out | 2 + tests/overlay/group | 1 + 3 files changed, 133 insertions(+) create mode 100755 tests/overlay/066 create mode 100644 tests/overlay/066.out diff --git a/tests/overlay/066 b/tests/overlay/066 new file mode 100755 index 00000000..285a5aff --- /dev/null +++ b/tests/overlay/066 @@ -0,0 +1,130 @@ +#! /bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (c) 2019 Chengguang Xu +# All Rights Reserved. +# +# FS QA Test 066 +# +# Test overlayfs copy-up function for variant sparse files. +# +seq=`basename $0` +seqres=$RESULT_DIR/$seq +echo "QA output created by $seq" + +here=`pwd` +tmp=/tmp/$$ +status=1 # failure is the default! +trap "_cleanup; exit \$status" 0 1 2 3 15 + +_cleanup() +{ + cd / + rm -f $tmp.* +} + +# get standard environment, filters and checks. +. ./common/rc +. ./common/filter + +# remove previous $seqres.full before test. +rm -f $seqres.full + +# real QA test starts here. + +# Modify as appropriate. +_supported_fs generic +_supported_os Linux +_require_test +_require_scratch + +# Remove all files from previous tests +_scratch_mkfs + +# We have totally 14 test files in this test. +# The detail as below: +# 1 empty file(10M) + 2^0(K)..2^11(K) hole size files(each 10M) + 1 random hole size file(100M). +# +# Considering both upper and lower fs will fill zero when copy-up +# hole area in the file, this test at least requires double disk +# space of the sum of above test files' size. + +_require_fs_space $OVL_BASE_SCRATCH_MNT $(((10*1024*13 + 100*1024*1) * 2)) + +lowerdir=$OVL_BASE_SCRATCH_MNT/$OVL_LOWER +upperdir=$OVL_BASE_SCRATCH_MNT/$OVL_UPPER +testfile="copyup_sparse_test" + +# Create a completely empty hole file(10M). +file_size=10240 +$XFS_IO_PROG -fc "truncate ${file_size}K" "${lowerdir}/${testfile}_empty_holefile" \ + >>$seqres.full + +# Create 2^0(K)..2^11(K) hole size test files(each 10M). +# +# The pattern is like below, both hole and data are equal to +# iosize except last hole. +# +# |-- hole --|-- data --| ... |-- data --|-- hole --| + +iosize=1 +max_iosize=2048 +file_size=10240 +max_pos=`expr $file_size - $max_iosize` + +while [ $iosize -le $max_iosize ]; do + pos=$iosize + $XFS_IO_PROG -fc "truncate ${file_size}K" \ + "${lowerdir}/${testfile}_iosize${iosize}K_holefile" >>$seqres.full + while [ $pos -lt $max_pos ]; do + $XFS_IO_PROG -fc "pwrite ${pos}K ${iosize}K" \ + "${lowerdir}/${testfile}_iosize${iosize}K_holefile" >>$seqres.full + pos=`expr $pos + $iosize + $iosize` + done + iosize=`expr $iosize + $iosize` +done + +# Create test file with many random holes(hole size is between 1M and 5M), +# total file size is 100M. + +pos=2048 +max_pos=81920 +file_size=102400 +min_hole=1024 +max_hole=5120 + +$XFS_IO_PROG -fc "truncate ${file_size}K" "${lowerdir}/${testfile}_random_holefile" \ + >>$seqres.full + +while [ $pos -le $max_pos ]; do + iosize=$(($RANDOM % ($max_hole - $min_hole) + $min_hole)) + $XFS_IO_PROG -fc "pwrite ${pos}K ${iosize}K" \ + "${lowerdir}/${testfile}_random_holefile" >>$seqres.full + pos=`expr $pos + $iosize + $iosize` +done + +_scratch_mount + +# Open the test files, no errors are expected. +for f in $SCRATCH_MNT/*; do + $XFS_IO_PROG -c "open" $f >>$seqres.full +done + +echo "Silence is golden" + +# Check all copy-up files in upper layer. +iosize=1 +while [ $iosize -le 2048 ]; do + diff "${lowerdir}/${testfile}_iosize${iosize}K_holefile" \ + "${upperdir}/${testfile}_iosize${iosize}K_holefile" >>$seqres.full ||\ + echo "${upperdir}/${testfile}_iosize${iosize}K_holefile" copy up failed! + iosize=`expr $iosize + $iosize` +done + +diff "${lowerdir}/${testfile}_empty_holefile" "${upperdir}/${testfile}_empty_holefile" \ + >>$seqres.full || echo "${upperdir}/${testfile}_empty_holefile" copy up failed! +diff "${lowerdir}/${testfile}_random_holefile" "${upperdir}/${testfile}_random_holefile" \ + >>$seqres.full || echo "${upperdir}/${testfile}_random_holefile" copy up failed! + +# success, all done +status=0 +exit diff --git a/tests/overlay/066.out b/tests/overlay/066.out new file mode 100644 index 00000000..b60cc24c --- /dev/null +++ b/tests/overlay/066.out @@ -0,0 +1,2 @@ +QA output created by 066 +Silence is golden diff --git a/tests/overlay/group b/tests/overlay/group index ef8517a1..e22134df 100644 --- a/tests/overlay/group +++ b/tests/overlay/group @@ -68,3 +68,4 @@ 063 auto quick whiteout 064 auto quick copyup 065 auto quick mount +066 auto copyup
