Wire NCP 0x23/0x05 AFP Get File Information to a conservative read-only reply
for SYS:-style paths.
The WebSDK documents NCP 0x2222/35/05 as taking a Volume Number, AFP Entry ID,
request bit map, and AFP path modifier string, and returning an AFP file
information record with entry id, parent id, attributes, data and resource fork
lengths, offspring count, NetWare dates, Finder Info, long and short names,
owner id, access privileges, and ProDOS information. The SDK headers expose the
same call as AFPGetFileInformation() and NWAFPGetFileInformation(), with the
wire reply matching RECPKT_AFPFILEINFO.
Resolve the supplied path through the existing mars_nwe path machinery, require
the optional Netatalk/libatalk backend as for the entry-id probe, and fill the
fields that can be derived safely from Unix stat data and the existing libatalk
helpers. Finder Info and resource fork length are read through nwatalk when
present; entry ids fall back to the existing stat-derived AFP id until
persistent CNID/AppleDouble ids are implemented. Parent id and ProDOS-specific
data remain zero for now.
Add a Linux afp_file_info_smoke test using ncpfs/libncp so the new call can be
exercised without an AppleTalk client. The test sends raw SYS:-style paths with
directory handle 0, matching the verified AFP Entry ID smoke-test path.
This implements only the read-only AFP file information query for path-based
requests; entry-id-only lookup, persistent CNID mapping, and write-side AFP
semantics remain future work.
Add an optional Linux-side smoke test for the first implemented NetWare AFP endpoint.
The WebSDK documents NCP 0x2222/35/12 AFP Get Entry ID From Path Name as taking a NetWare directory handle and path string and returning a 32-bit AFP entry id. MARS-NWE now has a guarded implementation of that probe when the optional Netatalk/libatalk backend is compiled in, but exercising it does not require a real AppleTalk workstation.
Use the ncpfs/libncp client library as the test transport. ncpfs is commonly available on Linux mars_nwe test hosts and its NWRequestSimple() helper builds the same length-prefixed subfunction request format used by normal libncp callers. The test accepts standard ncpfs connection options such as -S, -U, -P, and -n, sends NCP 0x23/0x0c, and prints the returned entry id.
Keep the test out of normal builds behind MARS_NWE_BUILD_LINUX_TESTS because it depends on host ncpfs development headers/library and on a running server. Add an --allow-invalid-namespace mode so builds without the Netatalk backend can still run a negative smoke test and verify that AFP remains unavailable.
This adds test infrastructure only and does not change server protocol behavior.
