# Test Case: Many Small Files
|
|
|
|
**Test ID**: TC124-many-small-files
|
|
**Category**: Boundary & Stress
|
|
**Priority**: High
|
|
**Regression**: None
|
|
|
|
## Objective
|
|
|
|
Verify exact names, count, sizes, and hashes for 12,000 one-KiB files spread
|
|
over 12 directories.
|
|
|
|
## Preconditions
|
|
|
|
- Complete `G7-MANUAL-SETUP.md` and verify the source inventory.
|
|
|
|
## Manual Steps
|
|
|
|
```sh
|
|
G7=/root/repo22-g7
|
|
FIX=$G7/fixtures
|
|
SRCROOT=$FIX/sources/boundaries
|
|
IMAGE=$FIX/images/boundaries.erofs
|
|
MNT=/mnt/repo22-g7-tc124
|
|
E=$G7/evidence/TC124
|
|
mkdir -p "$MNT" "$E"
|
|
unit=$(mdconfig -a -t vnode -f "$IMAGE")
|
|
mount -t erofs -o ro "/dev/$unit" "$MNT"
|
|
(cd "$SRCROOT" && find many-small -type f -print | sort) > "$E/source.names"
|
|
(cd "$MNT" && find many-small -type f -print | sort) > "$E/target.names"
|
|
source_count=$(wc -l < "$E/source.names" | tr -d ' ')
|
|
target_count=$(wc -l < "$E/target.names" | tr -d ' ')
|
|
printf 'source_count=%s\ntarget_count=%s\n' "$source_count" "$target_count" \
|
|
| tee "$E/counts.txt"
|
|
test "$source_count" -eq 12000
|
|
test "$target_count" -eq 12000
|
|
cmp "$E/source.names" "$E/target.names"
|
|
(cd "$SRCROOT" && find many-small -type f -exec sha256sum {} + | sort) \
|
|
> "$E/source.hashes"
|
|
(cd "$MNT" && find many-small -type f -exec sha256sum {} + | sort) \
|
|
> "$E/target.hashes"
|
|
cmp "$E/source.hashes" "$E/target.hashes"
|
|
test "$(awk '$3 ~ /^sources\/boundaries\/many-small\// && $2 != 1024 \
|
|
{ bad++ } END { print bad + 0 }' \
|
|
"$FIX/SOURCE-INVENTORY.tsv")" -eq 0 || \
|
|
awk '$3 ~ /^sources\/boundaries\/many-small\// && $2 != 1024' \
|
|
"$FIX/SOURCE-INVENTORY.tsv"
|
|
umount "$MNT"
|
|
mdconfig -d -u "${unit#md}"
|
|
test -z "$(mount -p | awk -v m="$MNT" '$2 == m { print }')"
|
|
test -z "$(mdconfig -l | tr ' ' '\n' | grep -x "$unit")"
|
|
```
|
|
|
|
## PASS Gate
|
|
|
|
- Source and mounted name lists are identical and contain exactly 12,000
|
|
files.
|
|
- Every mounted SHA256 row equals the corresponding source row.
|
|
- Every many-small source file is exactly 1024 bytes.
|
|
- No missing inode, panic, hang, or cleanup leak occurs.
