Function Documentation

cnid_comp_fn()

int cnid_comp_fn ( const void * p1, const void * p2 )

static

sl_cnid_close()

void sl_cnid_close ( AFPObj * obj )

static

sl_cnid_close_query()

void sl_cnid_close_query ( slq_t * slq )

static

sl_cnid_extract_term()

char * sl_cnid_extract_term ( TALLOC_CTX * mem_ctx, const char * qstring )

static

Extract a filename search term from a Spotlight query string.

Handles the common macOS patterns: kMDItemFSName = "foo*"cd → "foo" kMDItemDisplayName = "*foo*"cd → "foo" _kMDItemFileName = "foo*"cd → "foo"

Returns a talloc-allocated copy of the extracted term, or NULL if the query does not contain a supported filename predicate.

sl_cnid_fetch_results()

int sl_cnid_fetch_results ( slq_t * slq )

static

sl_cnid_fill_results()

int sl_cnid_fill_results ( slq_t * slq )

static

Emit up to SL_CNID_PAGE_SIZE results from the private CNID buffer.

Iterates over the remaining entries in csq->cnids[csq->pos..csq->count-1], resolving each CNID to a filesystem path and adding it to query_results. Stops after SL_CNID_PAGE_SIZE accepted results or when the buffer is exhausted, whichever comes first.

Sets slq_state to: SLQ_STATE_FULL — page is full, more results remain; client must poll SLQ_STATE_DONE — all results have been delivered SLQ_STATE_ERROR — add_filemeta() failed

Returns

0 on success, -1 on error

sl_cnid_init()

int sl_cnid_init ( AFPObj * obj )

static

sl_cnid_open_query()

int sl_cnid_open_query ( slq_t * slq )

static

sl_cnid_to_path()

char * sl_cnid_to_path ( TALLOC_CTX * mem_ctx, const struct vol * vol, cnid_t cnid )

static

Reconstruct the full filesystem path for a CNID.

Walks the DID chain upward via repeated cnid_resolve() calls, prepending path components, until reaching DIRDID_ROOT (the volume root).

Parameters

mem_ctx	talloc context for the returned string
vol	volume whose CNID database to query
cnid	network-byte-order CNID (as returned by cnid_find)

Returns

talloc-allocated full path, or NULL on error
