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.

0, else the number of the case that disagreed

test001_add_x_dirs()

extern

test007_add_over_existing_key_leaves_one()

int test007_add_over_existing_key_leaves_one ( struct vol * vol )

extern

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.

Returns

0, else the number of the step that disagreed

test009_file_add_over_curdir_did()

int test009_file_add_over_curdir_did ( struct vol * vol )

extern

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

test010_full_cache_accepts_adds()

int test010_full_cache_accepts_adds ( struct vol * 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.

Parameters

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

Returns

0, else the number of the step that disagreed
