Test Case: FLAT_INLINE Zero-Length File

Test ID: TC032-flat-inline-zero

Objective

Verify an explicitly layout-2 zero-length compact inode returns clean EOF and zero allocation.

Fixture

Use images/inline-zero.erofs and source/inline/empty.txt. The transformer asserts compact FLAT_INLINE, size 0, valid CRC, and records the image/source hashes.

Procedure

stat -f 'size=%z blocks=%b mode=%p' "$mnt/empty.txt"
cmp /tmp/repo22-g1/source/inline/empty.txt "$mnt/empty.txt"
test "$(wc -c < "$mnt/empty.txt")" -eq 0
sha256 /tmp/repo22-g1/source/inline/empty.txt "$mnt/empty.txt"

Expected Results

• Size and byte count are zero, st_blocks=0, hashes match the empty source, and no read error occurs.
• Mount and cleanup succeed.
