◆ dircache_test_ghost_trim_selection()
| int dircache_test_ghost_trim_selection |
( |
void |

|
|
extern |
Ghost-trim selection never yields the pinned entry.
Throwaway queues suffice: only the choice of node is under test.

A second entry may never be published under a key already in use.
A key may name only one entry. Adds over both keys — (vid, did) and (vid, pdid, uname) — with curdir on the entry being retired, the case that drives a recovery lookup back into dircache_add().
◆ test008_reindex_over_stale_key_expunges()
| int test008_reindex_over_stale_key_expunges |
( |
struct vol * |
vol | ) |
|
|
extern |
Re-keying onto a name a stale entry still holds retires the holder.
dir_modify(DCMOD_PATH) re-inserts under the destination key; a stale cache entry for that key must be expunged, or the key would name two entries.

curdir survives its entry being expunged by a file
A file colliding on the (vid, did) key retires the cached directory — a mid-session CNID reset can hand a file a directory's stale did. A file cannot stand in as curdir, so curdir must land on the volume root, never NULL.
- Returns
- 0, else the number of the step that disagreed

vol, |

unsigned int |
cache_size |
|
) |
| |
|
extern |
A full dircache keeps accepting inserts.
A cached entry and its ghost both occupy a hash slot, so once the working set exceeds the cache size the hash sits at its 2c capacity; every add past that point must release a slot before it inserts, or hash_insert()'s capacity assert aborts. Ghosts appear only where an eviction demotes a frequently-used entry, so each add is promoted at once: the entry moves to T2 and its eventual eviction lands in B2, filling the cache to 2c. The margin beyond that drives inserts against a cache pinned at capacity.
Promoted rather than looked up: the planted names do not exist on disk, so a lookup that validated would stat through the parent and expunge.

| [in] | vol | volume the entries are planted on |
| [in] | cache_size | the size dircache_init() was called with |
