# 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
|
|
|
|
```sh
|
|
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.
