# Test Case: Repeated Negative Lookup Behavior
|
|
|
|
**Test ID**: TC052-namecache-miss
|
|
**Category**: VFS Integration
|
|
**Priority**: High
|
|
|
|
## Objective
|
|
|
|
Verify repeated missing-name lookups consistently return ENOENT and do not
|
|
poison a later positive lookup. This is behavior-level negative-namecache
|
|
coverage, not proof of an internal cache hit.
|
|
|
|
## Procedure
|
|
|
|
Mount vfs/vfs-plain.erofs and run:
|
|
|
|
./g3_vfs_probe expect-error stat \
|
|
/tmp/repo22-g3/mnt/testdir/cache-missing 2
|
|
./g3_vfs_probe expect-error stat \
|
|
/tmp/repo22-g3/mnt/testdir/cache-missing 2
|
|
./g3_vfs_probe expect-success stat \
|
|
/tmp/repo22-g3/mnt/testdir/file.txt
|
|
|
|
## Expected Results
|
|
|
|
Both negative syscalls report errno 2 and the positive control succeeds.
|
|
Record the stable behavior honestly, with no latency-based cache assertion,
|
|
then clean the mount and md.
