Add the older WebSDK/NWAFP AFP Scan File Information subfunction 0x0a to the AFP dispatcher and route it through the existing conservative directory-scan implementation used by AFP 2.0 Scan File Information 0x11.
The Micro Focus NCP documentation describes both scan variants as read-only directory/file information scans with a Mac base Entry ID, Mac last-seen ID, DesiredResponseCount, SearchBitMap, RequestBitMap, and path modifier. The mars_nwe compatibility subset still requires a raw path-backed VOL:-style request because persistent CNID/base-ID lookup is not available yet, but accepting 0x0a lets older AFP callers probe the same read-only semantics instead of receiving Invalid Namespace for an otherwise implemented scan shape.
Teach the scan parser to accept the documented DesiredResponseCount word while keeping compatibility with the earlier compact smoke-test layout that omitted it. For now DesiredResponseCount is logged and constrained by the smoke helper, while the server still returns one conservative file-info record plus the next-last-seen entry id per request. This avoids pretending to implement full multi-response AFP directory scans before CNID-backed ordering, response-count batching, and AppleDouble metadata are available.
Extend afp_scan_info_smoke with --afp10/--afp20 selection and a documented --desired-count argument. The helper now sends the WebSDK-style request layout by default, uses 0x11 unless --afp10 is requested, and keeps the existing next_last_seen output used for iterative Linux smoke tests.
Tests:
- git diff --check
- gcc -fsyntax-only tests/linux/afp_scan_info_smoke.c with local ncpfs header stubs
- cmake --build build-off --target nwconn with ENABLE_NETATALK_LIBATALK=OFF
- cmake --build build-on --target nwconn with ENABLE_NETATALK_LIBATALK=ON against Netatalk 4.4.3 headers and local link stubs
TODO:
- Implement persistent CNID/base-ID lookup so entry-id-only scans can work without a raw path.
- Replace the one-record smoke response with true DesiredResponseCount batching once stable CNID ordering and full AFP scan filtering are available.
- Fill richer AppleDouble/Finder/ProDOS/resource-fork metadata when the libatalk backend grows write-safe metadata support.
Wire NCP 0x23/0x11 AFP 2.0 Scan File Information to a conservative read-only directory scan.
The WebSDK documents NWAFPScanFileInformation as taking a volume number, AFP base entry id, last-seen AFP id, search mask, request mask, path string, and file-info buffer. The call scans a directory relative to the AFP base and returns AFP file information for the next matching entry, updating the last-seen id for the caller's next iteration.
Reuse the existing AFP file information formatter and libatalk/stat-derived entry-id path. For now, support path-backed scans only: resolve the supplied SYS:-style path through the mars_nwe path machinery, enumerate one child directory entry after the supplied last-seen id, and return a last-seen id plus an AFP file-info record. Entry-id-only scans, persistent CNID lookup, and full AFP search-mask semantics remain future work.
Add a Linux afp_scan_info_smoke helper using ncpfs/libncp so the new endpoint can be exercised without an AppleTalk client.
This implements the documented read-only scan path needed for directory browsing smoke tests, while keeping write-side AFP and persistent Mac namespace semantics unchanged.
