Test Case: FLAT_PLAIN Medium File

Test ID: TC029-flat-plain-medium

Objective

Verify complete and nonzero-offset reads of a multi-block FLAT_PLAIN file.

Fixture

Use images/flat.erofs, source/flat/medium.dat, and expected/medium-10-5.bin. Evidence asserts layout 0 and size 102417.

Procedure

stat -f 'size=%z blocks=%b' "$mnt/medium.dat"
cmp /tmp/repo22-g1/source/flat/medium.dat "$mnt/medium.dat"
./read_probe pread "$mnt/medium.dat" 40960 20480 /tmp/tc029-range
cmp /tmp/repo22-g1/expected/medium-10-5.bin /tmp/tc029-range
sha256 /tmp/repo22-g1/source/flat/medium.dat "$mnt/medium.dat" \
  /tmp/repo22-g1/expected/medium-10-5.bin /tmp/tc029-range

Remove the range output, unmount, and detach.

Expected Results

• Full file and the five-block range match their deterministic sources.
• No block-boundary truncation or cleanup failure occurs.
