# Test Case: Metabox-backed shared xattrs
|
|
|
|
**Test ID**: TC081-metabox-backed-xattr
|
|
**Fixture**: `metabox-plain.erofs`, `/metabox-a`, `/metabox-b`
|
|
|
|
## Objective
|
|
|
|
Verify shared entries, inline entries, and long-prefix shared entries from a
|
|
metabox logical stream. Require `SHARED_EA_IN_METABOX`, `xattr_blkaddr=1`,
|
|
carrier size/bounds, shared IDs, and prefix fields in the generator manifest.
|
|
|
|
## Manual steps
|
|
|
|
```sh
|
|
lsextattr user /mnt/repo22-g4/metabox-a
|
|
getextattr -qq -x user metaboxshared /mnt/repo22-g4/metabox-a
|
|
getextattr -qq -x user metaboxshared /mnt/repo22-g4/metabox-b
|
|
getextattr -qq -x user shared-prefix-key /mnt/repo22-g4/metabox-a
|
|
getextattr -qq -x user repo22.application.component.setting \
|
|
/mnt/repo22-g4/metabox-a
|
|
```
|
|
|
|
## Expected results
|
|
|
|
Values are `nonzero-base`, `nonzero-base`, `shared-value`, and
|
|
`long-prefix-value`; all names list once. Clean up.
