# Test Case: Long-prefix backing selection
|
|
|
|
**Test ID**: TC135-prefix-metabox-and-primary-fallback
|
|
**Fixtures**: `metabox-plain.erofs`, `basic.erofs`, `prefix-primary.erofs`
|
|
|
|
## Objective
|
|
|
|
Verify prefix table selection in order: metabox, packed inode, then primary
|
|
metadata. The manifest must prove each backing and record all changed super
|
|
fields and image hashes.
|
|
|
|
## Manual steps
|
|
|
|
Use a separate attach/mount/cleanup cycle for each image:
|
|
|
|
```sh
|
|
# metabox-plain.erofs
|
|
lsextattr user /mnt/repo22-g4/metabox-a
|
|
getextattr -qq -x user repo22.application.component.setting \
|
|
/mnt/repo22-g4/metabox-a
|
|
|
|
# basic.erofs (packed backing)
|
|
lsextattr user /mnt/repo22-g4/prefix-user-0
|
|
getextattr -qq -x user repo22.application.component.setting \
|
|
/mnt/repo22-g4/prefix-user-0
|
|
|
|
# prefix-primary.erofs (PLAIN_XATTR_PFX)
|
|
lsextattr user /mnt/repo22-g4/prefix-user-0
|
|
getextattr -qq -x user repo22.application.component.setting \
|
|
/mnt/repo22-g4/prefix-user-0
|
|
```
|
|
|
|
## Expected results
|
|
|
|
Values are `long-prefix-value`, `prefix-value-0`, and `prefix-value-0`.
|
|
Every cycle cleans its mount and md provider.
